What’s the difference between bag packing machine and bag packaging machine?
The bag-type packaging machine means that the customer has a designed and shaped bag, and the machine is only responsible for filling and sealing, while the bag-making packaging machine means that there is a roll film on the equipment, and the machine automatically forms a bag (the size is adjustable), filling and sealing.
Compared with the bag-type packaging machine, the bag can be made a little richer, but it is more troublesome than the bag-type packaging machine.
Types of rapid prototyping equipment
Type of equipment:
3D scanner, rapid prototyping machine, CMM / instrument reverse engineering soft / point cloud processing / 3D detection software, FreeForm tactile design system has a lot of related information to take a look!
The principle, technological process and technical characteristics of rapid prototyping technology:
Rapid prototyping belongs to discrete / stacking prototyping. It puts forward a brand-new thinking mode dimensional model based on the forming principle, that is, the three-dimensional model of the part made on the computer is gridded and stored, and the two-dimensional profile information of each layer is obtained by layering. According to these profile information, the processing path is automatically generated, and the forming head selectively solidifies or cuts layers of forming materials under the control of the control system to form each profile sheet. And gradually and sequentially superimposed into three-dimensional blank. Then the blank is post-processed to form the part.
The process of rapid prototyping is as follows:
L) the construction of product 3D model. Because the RP system is directly driven by the 3D CAD model, it is necessary to build the 3D CAD model of the machined workpiece. The three-dimensional CAD model can be directly constructed by computer-aided design software (such as Pro/E, I-DEAS, Solid Works, UG, etc.), or the two-dimensional drawings of the existing products can be transformed to form a three-dimensional model, or the product entity can be scanned by laser and CT to obtain point cloud data, and then the reverse engineering method can be used to construct the three-dimensional model.
2) approximate treatment of 3D model. Because the products often have some irregular free-form surfaces, the model should be approximately processed before machining to facilitate the follow-up data processing work. Because the STL format is simple and practical, it has become a quasi-standard interface file in the field of rapid prototyping. It uses a series of small triangle planes to approach the original model, each small triangle is described by three vertex coordinates and a normal vector, and the size of the triangle can be selected according to the accuracy requirements. STL files have two output forms: binary code and ASCll code. The output space of binary code is much smaller than that of ASCII code, but the output form of ASCII code can be read and checked. Typical CAD software has the function of converting and outputting STL format files.
3) slicing of 3D model. The appropriate machining direction is selected according to the characteristics of the machined model, and the approximate model is cut by a series of planes with certain intervals in the forming height direction, so as to extract the profile information of the section. The interval is usually 0.05mm~0.5mm, and 0.1mm is commonly used. The smaller the interval is, the higher the forming precision is, but the longer the forming time is, the lower the efficiency is. On the contrary, the precision is low, but the efficiency is high.
4) forming and processing. According to the profile of the slice, under the control of the computer, the corresponding molding head (laser head or sprinkler) scans according to the profile information of each section, accumulates the material layer by layer on the worktable, and then binds each layer to get the prototype product.
5) the post-processing of the molded parts. The molded parts are taken out from the forming system, polished, coated, or sintered in a high-temperature furnace to further improve their strength.
Rapid prototyping has the following important features:
L) it can make any complex 3D geometric solid. Due to the principle of discrete / stacking molding, it simplifies a very complex three-dimensional manufacturing process to the superposition of two-dimensional processes, and can realize the machining of parts with arbitrary complex shapes. The more complex parts are, the more they can show the superiority of RP technology. In addition, RP technology is especially suitable for parts that are difficult or even impossible to be manufactured by traditional methods, such as complex cavities and complex surfaces.
2) rapidity. The design and machining information of a new part can be obtained by modifying or reorganizing a CAD model. Parts can be made from a few hours to dozens of hours, with the outstanding characteristics of rapid manufacturing.
3) highly flexible. Complex manufacturing processes can be completed without any special fixtures or tools, and tooling, prototypes or parts can be manufactured quickly.
4) Rapid prototyping technology has realized the two advanced goals pursued by mechanical engineering for many years, that is, the integration of material extraction (gas, liquid-solid phase) process and manufacturing process and the integration of design (CAD) and manufacturing (CAM).
5) combined with reverse engineering (Reverse Engineering), CAD technology, network technology, virtual reality and so on, it has become a powerful tool for product speed development.
Therefore, rapid prototyping technology plays a more and more important role in the manufacturing field, and will have an important impact on the manufacturing industry.
Classification of rapid prototyping technology:
According to the prototyping methods, rapid prototyping can be divided into two categories: laser and other light source based prototyping (Laser Technology), such as light curing molding (SLA), layered solid manufacturing (LOM), selective laser powder sintering (SLS), shape deposition molding (SDM), etc.; spray based prototyping (Jetting Technoloy), such as melt deposition molding (FDM), three-dimensional printing (3DP), multiphase spray deposition (MJD). The following is a brief introduction to the more mature processes.
1. SLA (Stereolithogrphy Apparatus) process SLA process, also known as light modeling or stereolithography, was patented by Charles Hul in 1984. In 1988, the American 3D System Company launched the commercial prototype SLA-I, which is the first rapid prototyping machine in the world. Various types of SLA molding machines occupy a large share of the RP equipment market.
SLA technology is based on the photopolymerization principle of liquid photosensitive resin. This kind of liquid material can undergo photopolymerization rapidly under the irradiation of ultraviolet light of certain wavelength and intensity, and the molecular weight increases sharply, and the material changes from liquid to solid.
SLA working principle: the liquid tank is filled with liquid light-cured resin laser beam. Under the action of the deflection mirror, the laser beam can scan on the liquid meter. The scanning trajectory and the existence of light are all controlled by the computer. Where the light spot hits, the liquid will solidify. At the beginning of molding, the working platform is at a certain depth under the liquid surface. the focused light spot is scanned point by point on the liquid surface according to the instructions of the computer, that is, solidified point by point. When the first layer of scanning is completed. the unirradiated area is still liquid resin. Then the lifting platform drives the platform down one layer of height, and the formed layer is covered with a layer of resin, and the scraper scrapes the viscous resin liquid surface, and then scans the next layer, and the new weekly layer is glued to the previous layer, which is repeated until the whole part is manufactured to get a three-dimensional solid model.
SLA method is the most widely studied method in the field of rapid prototyping technology at present, and it is also the most mature method in technology. The precision of the parts molded by SLA process is high, the machining precision can generally reach 0.1mm, and the utilization rate of raw materials is nearly 100%. However, this method also has some limitations, such as the need for support, the decrease of accuracy caused by resin shrinkage, the toxicity of light-cured resin and so on.
2. LOM (Laminated Object Manufacturing,LOM) process LOM process is called laminated solid manufacturing or layered solid manufacturing, which was successfully developed by Michael Feygin of Helisys Company in 1986. LOM process uses thin sheet materials, such as paper, plastic film and so on. The surface of the sheet is coated with a layer of hot melt adhesive in advance. During processing, the hot pressing roller hot-pressed the sheet to make it bonded with the formed workpiece below. The CO2 laser is used to cut the part profile and the outer frame of the workpiece on the newly bonded layer, and the mesh aligned up and down is cut in the redundant area between the profile and the outer frame. After the laser cutting is completed, the worktable drives the formed workpiece to drop and separate from the ribbon sheet. The feeding mechanism rotates the receiving shaft and the feeding shaft to drive the movement of the material belt and move the new layer to the processing area. The working joint rises to the processing plane, the hot pressing roller is hot pressed, the number of layers of the workpiece is increased by one layer, and the height is increased by one material thickness. Then cut the profile on the new layer. This is repeated until all sections of the parts are bonded and cut. Finally, the shredded superfluous parts are removed and the layered solid parts are obtained.
The LOM process only needs to cut the profile of the section of the part on the sheet, instead of scanning the whole section. Therefore, the speed of forming thick-walled parts is fast, and it is easy to manufacture large parts. There is no material phase transformation in the process, so it is not easy to cause warping deformation. The excess material between the outer frame of the workpiece and the profile plays a supporting role in the machining, so the LOM process does not need to be supported. The disadvantage is that the material is wasted seriously and the surface quality is poor.
3. SLS (Selective Laser Sintering) process SLS process is called selective laser sintering, which was successfully developed by C.R.Dechard of the University of Texas at Austin in 1989. The SLS process is made of powdery materials. The material powder is spread on the upper surface of the formed part and scraped flat, and the cross section of the part is scanned on the newly laid new layer with a high intensity CO2 laser. The material powder is sintered together under high intensity laser irradiation, and the cross section of the part is obtained and connected with the formed part below. When the first layer of cross-section is sintered, a new layer of material powder is laid and the lower cross-section is selectively sintered.
After the sintering is completed, the excess powder is removed, and the parts are obtained by grinding, drying and other treatment.
The SLS process is characterized by a wide range of material adaptations, which can make not only plastic parts, but also ceramic, wax and other material parts, especially metal parts. This makes the SLS process attractive. The SLS process does not need to be supported because the unsintered powder plays a supporting role.
4. 3DP (Three Dimension Printing) 3D printing process was developed by E-manual Sachs, Massachusetts Institute of Technology, USA. It has been commercialized by Soligen Company of the United States in the name of DSPC (Direct Shell Production Casting) to manufacture ceramic shells and cores for casting.
The 3DP process is similar to the SLS process, which is formed by powder materials, such as ceramic powder and metal powder. The difference is that the material powder is not connected by sintering, but the cross section of the part is “printed” on the material powder with a binder (such as silica gel) through the nozzle.
The strength of the parts bonded with binder is low and needs post-treatment. First burn the binder, and then infiltrate the metal at high temperature to densify the parts and improve the strength.
5. FDM (Fused Depostion Modeling) fused deposition manufacturing (FDM) process was successfully developed by American scholar Scott Crump in 1988. The materials of FDM are generally thermoplastic materials, such as wax, ABS, nylon and so on. Feed in the form of silk. The material is heated and melted in the sprinkler. The nozzle moves along the profile and filling track of the part, while extruding the melted material, which solidifies quickly and condenses with the surrounding material.
The application fields of rapid prototyping technology:
At present, in terms of the development level of RP technology, it is mainly applied to the design verification of the development of new products (including product upgrading) and the trial production of simulation samples, that is, to complete the development process of product conceptual design (or modification design)– modeling design– structural design– basic function evaluation– simulation sample trial production. Some products based on plastic structure can also be trial-produced in small batches, or some physical functional tests, assembly verification, actual appearance effect examination, and even small batch assembly of products can be put on the market in advance to achieve the purpose of throwing stones and asking the way.
The application of rapid prototyping is mainly reflected in the following aspects:
(1) Design verification and function verification in the process of new product development. RP technology can quickly transform the CAD model of product design into a physical model, which can easily verify the designer’s design idea and the rationality, assemblability and aesthetics of the product structure, and find that the problems in the design can be modified in time. If the traditional method is used, it is necessary to complete many links, such as drawing, process design, tooling and mold manufacturing, which has a long cycle and high cost. If it is put into production without design verification, once there is a design error, it will cause great losses.
(2) the inspection of manufacturability and assemblability, inquiry of supply and market promotion, testing and design of manufacturability and assemblability of complex systems with limited space, such as automobiles, satellites and missiles by RP method, will greatly reduce the difficulty of design and manufacture of such systems. For complex parts that are difficult to determine, RP technology can be used for trial production to determine the best and reasonable process. In addition, RP prototype is also an effective means of communication in all aspects of product design and commercialization. For example, to provide customers with product samples, market promotion and so on, rapid prototyping technology has become a technical approach of concurrent engineering and agile manufacturing.
(3) Direct production of single pieces, small batches and special complex parts. For the parts of polymer materials, high-strength engineering plastics can be used for direct rapid prototyping to meet the requirements; for complex metal parts, they can be obtained by rapid casting or direct metal parts molding. This application is of special significance to the aviation, aerospace and defense industries.
(4) Rapid mold manufacturing. Through various conversion technologies, the RP prototype is converted into a variety of rapid moulds, such as low melting point alloy mold, silica gel mold, metal cold spray mold, ceramic mold, etc., to produce small and medium batches of parts to meet the development trend of rapid product upgrading and smaller and smaller batches. The application field of rapid prototyping includes almost every industry in the field of manufacturing, and it has been more and more widely used in medical treatment, ergonomics, cultural relic protection and other industries.
The main applications of rapid prototyping technology the applications of various industries are as follows:
◆ automobile, motorcycle: design, modification, assembly test of shape and interior parts, trial production of engine and cylinder head.
◆ home appliances: all kinds of home appliances shape and structure design, assembly test and function verification, market promotion, mold manufacturing.
◆ communication products: product shape and structure design, assembly test, function verification, mold manufacturing.
◆ Aeronautics and Aerospace: direct manufacture of special parts, trial production of impeller, turbine and blade, trial production and assembly test of engine.
◆ light industry: all kinds of product design, verification, assembly, market promotion, rapid manufacturing of toys, footwear moulds.
◆ Medical: design, trial production and trial of medical devices, materialization of CT scanning information, surgical simulation, preparation of human bones and joints.
◆ national defense: design, assembly and trial production of various weapon parts, direct production of special parts, model production of remote sensing information.
In a word, the development of rapid prototyping technology is a breakthrough in the manufacturing field in the past 20 years. It is not only different from traditional methods in manufacturing principle, but also RP technology can shorten the product development cycle, reduce development costs and improve the competitiveness of enterprises when the current industrial strategy takes market response speed as the first. Here are some examples to illustrate the role of this technology in the product development process.
1. Design verification: used for new product appearance design certificate and structural design verification, find out design defects and improve product design. In modern product design, the design means are becoming more and more advanced, and computer-aided design makes product design fast and intuitive, but due to the limitations of software and hardware, designers are still unable to directly evaluate the effectiveness and structure of the designed products as well as the feasibility of the production process. Rapid prototyping technology provides advanced technical means for designers to get product samples quickly and evaluate products intuitively. Our company made a sample panel for the new 250 motorcycle in a motorcycle factory, including 13 pieces of fuel tank, front and rear bezel, seat and side cover. Using AFS molding technology, all the production was completed in 12 days. The designer installed the sample on the car body, and after careful evaluation and repeated comparison, the appearance of the product was re-modified and reached the ideal state. This verification process makes the design more perfect and avoids the waste caused by blind production.
2. Assembly verification: make the sample and carry on the assembly experiment. A company in Tianjin commissioned us to process the shell of the fax machine and the telephone. Users should not only evaluate the appearance, but also put the internal parts of the fax machine into the sample for assembly experiment and structure evaluation. The company first chose the traditional processing method, block processing, manual bonding, processing only a set of telephone handset costs thousands of yuan, takes 20 days. It is estimated that it will take 2 months to make the fax machine sample, and the cost is 25,000 yuan. Our company uses rapid prototyping technology to deliver a total of six pieces of the product to the consignor in only 15 days. In the assembly experiment, the user found 7 assembly interference and unreasonable structure. Compared with the two methods, the traditional processing methods of BABS plastic assembly samples of fax machine are numerous, manual splicing is time-consuming and laborious, and the material is wasted and the processing cycle is long. For complex structures and surfaces, the machining is rough, the dimensional precision is low, and the one-to-one corresponding relationship between the physical model and the design model can not be established, so it is difficult to detect design errors in assembly experiments. The automatic forming method has the advantages of high automation, one-time forming, short cycle and high precision, and has an one-to-one corresponding relationship with the design model, so it is more suitable for the production and manufacture of sample assemblies.
3. Function verification: our company makes the cylinder head of 250 double-cylinder motorcycle for a motorcycle factory. This is a newly designed engine, users need 10 samples for engine simulation experiments. The part has a complex internal structure, traditional machining can not be processed, can only be used casting molding. The whole process needs to go through mold opening, core making, mold assembly, casting, sandblasting and machining, which is the same as the actual production process. Among them, it takes three months to open the mold alone. This is unacceptable for small batch sample production both in terms of time and wood. Using selective laser sintering technology, using precision casting investment mold material as molding material, 10 pieces of casting mold of this part were processed in only 5 days on the rapid prototyping machine, and then the casting blank was obtained 10 days later. After the necessary machining, the trial production of this engine was completed in 30 days.
4. rapid casting: in the manufacturing industry, especially in key industries such as aviation, aerospace, national defense, automobile and other key industries, the core components of the common foundation are generally metal parts. and a considerable number of metal parts are asymmetrical, irregular curved surfaces or parts with complex structure and fine structure inside. These parts are often produced by casting or disassembly processing. In foundry production, the manufacture of templates, core boxes, wax pressing moulds and die-casting moulds is often completed by machining, and sometimes fitters are needed for trimming, which is not only a long cycle and high cost, but also a multi-link and complex process from mold design to manufacturing, and mistakes will lead to full rework. Especially for some castings with complex shapes, such as blades, impellers, engine cylinder blocks, cylinder heads, etc., the manufacture of moulds is a more difficult problem, even if expensive equipment such as CNC machining centers are used. There are still great difficulties in processing technology and process feasibility. It can be imagined that if we encounter the trial production or small batch production of such parts, the manufacturing cycle, cost and risk are quite large.
Laser rapid prototyping technology has been proved to be a very effective means to solve the manufacturing of small batches of complex parts. So far, we have successfully produced more than a thousand sweep drills, including leaf bell, blade, engine rotor, pump block, engine cylinder block, cylinder head and so on. We call the combination of rapid prototyping and casting technology rapid casting technology. Figure 5 shows the comparison between the rapid casting process and the traditional casting process. Because there is no need to open the mold in the rapid casting process, the manufacturing cycle and cost are greatly saved. Figure 6 shows the gas two-motor S section produced by rapid casting method. The parts are 80Omm in diameter and 410m high. They are manufactured according to the traditional metal casting method. The mold manufacturing cycle is about half a year and the cost is hundreds of thousands. Using rapid casting method, rapid prototyping casting mold for 7 days (divided into 6 stages), assembly, combination, casting for 10 days, the cost of each piece is not more than 20,000 (a total of 6 pieces). For the casting mold of the new tank supercharger produced by the rapid prototyping method, we completed the production of 37 wax moulds in 5 days, making the whole trial production task 3 months ahead of schedule.
5. Turn-over molding: in practical application, many products can only be processed through the mold. It is a time-saving and cost-saving method to use the molding machine to make the product sample first and then turn the mold. The prototype of engine pump shell is difficult to be machined by traditional machining method and must be molded. It is estimated that the opening time of the mold will take 8 months and the cost is at least 300000. If the product design is wrong, the whole set of molds will be scrapped. We use the rapid prototyping method to make a plastic sample for the product, which is used as the master mold for remaking the silicone mold. The master mold is fixed in the aluminum standard mold frame, poured into the prepared silicone rubber, placed for 12.20 hours, the silicone rubber is completely solidified, the mold frame is opened, the silicone rubber is cut along the predetermined parting line with a knife, and the master mold is taken out. the silicone mold used to cast the wax mold of the pump shell is successfully reproduced. Through this mold, the wax mold is produced, and after shell coating, roasting, wax loss, pressure casting and sandblasting, a qualified pump shell casting is manufactured in a short period of two months and can be installed and run after necessary machining. The whole trial production cycle is 2/3 shorter than that of the traditional method, and the cost is saved by 3/4.
6. Sample production: manufacture product substitutes for displaying new products and marketing, such as communications, home appliances and building model production.
7. process and material verification: rapid production of various wax molds for the exploration and verification of new precision casting processes and new materials, as well as the testing of auxiliary tools and components needed for new product manufacturing. The experiment of nearly no spare precision casting blade. First of all, several blade wax moulds are made by molding machine according to different shrinkage, and then shell, numbering and wax loss casting. The obtained blade castings are measured and repeated several times to determine the shrinkage of investment casting of different materials, which lays a foundation for batch production. If the test is carried out by opening the mold, the cost and cycle will be greatly increased. The engine high-speed turbine requires high quality and compact castings. Four wax moulds for precision casting were made by using laser rapid automatic molding machine, numbered coating shell and special alloys with different proportions. The four samples were tested and compared to determine the best formula of the material. It takes only a month from modeling to getting the result.
8. Reverse engineering and rapid prototyping: a prototype of the front panel of a motorcycle molded by a molding machine, which contains a cover of headlights and two side lights, which form a complete curved surface with the panel. This is a typical example of detailed design of parts by reverse engineering. In the whole process, the model worker first makes the conceptual model with sludge according to the requirements of the overall image of the motorcycle, and then digitalizes it with a three-coordinate measuring instrument after evaluation. The measured data are sorted out and converted into a curved surface model by the Scantools module of the Pro/E software, and then converted into a solid model and calculated in “details”. Finally, the sample model is made by the forming mechanism, and then it is installed on the motorcycle for appearance and assembly inspection after polishing and painting. The whole process takes only one week from the completion of the three-coordinate measurement to the sample. The sample model obtained at this time is different from the original clay model, and becomes a part model with the same wall thickness and size as the actual part, with complete structures such as tendons and holes, which is undoubtedly a great progress compared with the sludge model. If the model needs to be modified at this time, it can be done on the CAD system. When the appearance and detail structure of the model are determined correctly, the final model data can be used for mold design and processing.
What is the third generation sanding machine? What’s the difference between a sand maker and an ordinary sand maker?
The development of society is obvious to all. The demand for sand and gravel aggregate in China, which is known as infrastructure madness, is increasing. Natural sand can no longer meet the needs of people. Artificial sand produced by sand making machine has become a substitute for natural sand. Widely used in a variety of infrastructure projects. At present, the sand-making machine for the production of artificial sand is also being upgraded, and now a new type of third-generation sand-making machine is very popular. This paper introduces the working principle and superior performance of this equipment.
Operation principle of new third generation sand making machine equipment
The discharge particle size of the new third-generation sand making machine is relatively fine, so it is also called fine crusher. The operation principle of the new third generation sand making machine: it is a kind of continuous operation equipment. During operation, the material enters the crushing chamber from the feed port and meets the hammerhead of the high-speed rotating rotor driven by the motor. The material is initially broken by the action between the hammering and the reaction plate. After repeated hammering many times with high frequency, the material forms a pile on the middle diaphragm and falls on the throwing plate of the high-speed rotating lower rotor. It is also thrown at a high speed to hit and fall on the reaction board, and the rotating plate hammer is forced to counterattack, crush, grind, and then discharge through the material outlet.
In the process of crushing, it not only completes the impact and crushing between the material and the plate hammer and counterattack liner, but also completes the stone shaping operation between each plate hammer and in the crushing chamber, so the quality of the sand produced by it is very high.
The advantages of the new third generation sand making machine equipment

3. It changes from three-stage crushing to two-stage crushing, the process is simplified, the structure is simple, the installation and maintenance are convenient, and the operation cost is low.
4. It is less affected by the water content of the material, and it can accept the material with less than 8% water content without blockage.
5. The new third-generation sand making machine meets the theme of modern environmental protection, with working noise less than 70 decibels, good sealing performance and less dust pollution.
6. The counterweight wheel is equipped on the basis of the old sand-making machine, the electric energy is saved, the kinetic energy is increased, and the production efficiency is improved.
7. Price is one of the most important factors for users. Compared with HVI sand-making machine, the new third-generation sand-making machine is cheaper and saves investment costs for users.
8. The supporting power it uses is small, and the production cost is lower than 35% 50% of other equipment of the same scale, but the output efficiency is higher than 35% of other equipment of the same scale.
To sum up, the new third-generation sand-making machine is a sand-making equipment designed and produced with reference to the advantages of existing sand-making machines and according to the real needs of users. it has the advantages of convenient particle size adjustment, uniform particle size, small grain size, large production capacity and long hammerhead life. low investment cost and other advantages.
What are the classifications of packaging machinery
The commonly used classification methods are classified according to the packaging process, which can be divided into main packaging machinery and auxiliary packaging machinery.
