What problems should be paid attention to in the production process of wooden packing box?

Wooden case packing is to avoid the loss caused by collision and shock in the course of transportation. for the purpose of safe transportation, it is very convenient to use and is liked by many people. It is widely used in international trade. There are many kinds of wooden packing boxes, which can be roughly divided into full blockade, semi-blockade and checkered boxes, and their sizes and weights are also different, so in many cases, when packing wooden cases, we need to pay attention to many problems: if the center of gravity of the wooden box is low, the large wooden packing box can only be packed on one floor and can not make full use of the bottom area of the box, it should be placed in the center of the container.

The bottom must be fixed horizontally with square strips of wood If you encounter a small wooden box during a loading, the seam loading method can be used to press the upper wooden box on the joint of the lower two wooden cases, and the top layer must be fixed or fastened; if it is a small wooden packing box, if there is a large gap at the end of the door, it must be fixed or fastened by wooden boards and strips. In most cases, the center of gravity of wooden cases is relatively high, and it is not enough to rely on the bottom, and wooden strips must be used to support them; when loading large wooden cases with extra heavy weight, concentrated or eccentric loads are often formed, so there must be special fixed facilities to prevent the goods from coming into contact with the front and rear walls of the container. If a frame wooden box is used for a device, steel straps are usually used to tighten, or elastic nylon belts or cloth belts are used instead of steel belts.

Main classification of packaging machinery

There are many ways to classify packaging machinery. According to the function, it can be divided into single-function packaging machine and multi-function packaging machine; according to the purpose of use, it can be divided into inner packaging machine and outer packaging machine; according to the packaging variety, it can be divided into special packaging machine and general packaging machine; according to the level of automation, it can be divided into semi-automata and full automata. The table shows the classification of packaging machinery.

There are many kinds of packaging machinery and there are many methods of classification. There are many kinds of packaging machines from different points of view, such as liquid, bulk, bulk, paste, laminating, electronic combination scale packaging and pillow packaging machine, inner packaging and outsourcing packaging machine according to packaging function, food, daily chemical and textile packaging machines according to packaging industry, and single-station and multi-station packaging machines according to packaging station. According to the degree of automation, there are semi-automatic, fully automatic packaging machines and so on.

There are many classification methods of packaging machinery, each of which has its own characteristics and scope of application, but all have their limitations. From the general situation of packaging machinery in the world, the more scientific classification method is to classify according to its main functions, which can grasp the essence of things. The basic categories are as follows:

(1) filling machine

A filling machine is a packaging machine that loads a precise number of packages into various containers. Its main types are: ① volumetric filling machine. Including measuring cup type, intubation type, plunger type, material level type, screw type, timing filling machine.

② weighing filling machine. Including intermittent weighing type, continuous weighing type, weighing-centrifugal and other fractional filling machines.

③ counter filling machine. Including single-piece counting type, multi-piece counting type filling machine.

(2) sealing machine

Sealing machine is a machine that seals containers filled with packages. its main types are: ① sealing machine without sealing material. Including hot pressure type, cold pressure type, fusion welding type, plug-in type, folding type and other sealing machines.

② has a sealing material sealing machine. Including rotary type, rolling type, crimping type, pressing type and other sealing machines.

③ has an auxiliary sealing material sealing machine. Including adhesive tape type, bonding type, binding type, binding type, sewing type and other sealing machines.

(3) wrapping machine

A wrapping machine is a packaging machine that wraps all or part of the packaging materials with flexible packaging materials. The main types are as follows:

① full-wrapped wrapping machine. Including kink type, covering type, fitting type, seam type and other wrapping machines.

② semi-wrapped wrapping machine. Including folding type, shrinkage type, stretching type, winding type and other wrapping machines.

(4) Multi-function packaging machine

This kind of packaging machine has two or more functions. The main types are: ① filling and sealing machine. It has two functions of filling and sealing.

② molding, filling and sealing machine. It has three functions of molding, filling and sealing. The types of molding include bag molding, bottle molding, box molding, blister forming, melting molding and so on.

③ type filling and sealing machine. It has the functions of shaping, filling and sealing. Stereotyped mode

④ double-sided sealing machine. It can seal both the cover and the bottom at the same time. When sealing the box, the box can be placed on the side or standing.

(3) classified according to the position and number of strips sealed by adhesive tape

① I box sealing machine. It is sealed with a piece of tape at the joint between the upper cover and the bottom of the box. This kind of sealing is easy to operate, but the sealing performance is poor.

② H box sealing machine. It is based on type I sealing, that is, two tapes are sealed at both ends of type I sealing tape, which is shaped like H, so it is called H type. It can increase the box strength and sealing performance, but the cost is high.

(4) classified according to the degree of specialization

① universal box sealing machine. It can adjust some mechanisms to change the relevant dimensions of the sealing machine to adapt to the sealing of boxes of various sizes. It has a wide range of adaptation and is a widely used sealing machine.

② special box sealing machine. It can only seal boxes of a certain size, the sealing speed is fast, and it is suitable for mass sealing operation. ③ random sealing machine. Within the prescribed size range, the relevant mechanisms can be changed automatically to meet the sealing needs of boxes of different sizes. it is a kind of sealing machine with a high degree of automation. According to the filling principle, the filling machine is divided into atmospheric filling machine, pressure filling machine and vacuum filling machine.

① atmospheric pressure filling machine: it is filled by liquid self-weight under atmospheric pressure. This kind of filling machine is divided into timing filling and constant volume filling, which is only suitable for filling low viscosity gasless liquids such as milk, wine and so on.

② pressure filling machine: it can be divided into two kinds: one is that the pressure in the storage tank is equal to the pressure in the bottle, and the filling depends on the self-weight of the liquid into the bottle, which is called isobaric filling; the other is that the pressure in the storage tank is higher than that in the bottle, and the liquid flows into the bottle by pressure difference, and this method is adopted in the high-speed production line. The pressure filling machine is suitable for filling gaseous liquids, such as beer, soda, champagne and so on.

③ vacuum filling machine: filling when the pressure in the bottle is lower than the atmospheric pressure. This kind of filling machine has the advantages of simple structure, high efficiency and wide adaptability to the viscosity of materials, such as oil, syrup, fruit wine and so on. The semi-automatic multi-function packaging machine integrates vacuum, nitrogen filling and heat sealing, and the working procedure is automatically controlled by the PLC programming system. The time of each working link can be adjusted separately according to different packaging materials and volumes, or one of them can be used alone. The whole machine is composed of oil and water removal air filtration system, air separation nitrogen production system, vacuum system, gas storage and supply system, heat seal system, PLC programming control system, lifting studio, frame and housing. This machine can be used with other equipment and production machines. Vacuum nitrogen-filled packaging will put the food into the bag, extract the air from the bag to a predetermined vacuum, and then fill it with nitrogen, carbon dioxide, oxygen and other gases, and then complete the sealing process.

It is suitable for all kinds of packaging of all kinds of plastic composite film and plastic aluminum foil composite film, vacuum packaging or vacuum nitrogen packaging for liquid, semi-fluid, solid granular, powder, paste food, fresh fruits, vegetables, rice, flowers, chemicals, precious medicinal materials, famous calligraphy and paintings, electronic original devices and all kinds of moth-proof, anticorrosive, moistureproof, mildew-proof and oxidation-proof articles. The main contents are as follows: 1. The appearance is beautiful and generous, which can be directly seen to its real form. Vacuum packaging shape is broken, it is not easy to check the true shape of its packaging products, the packaging grade is not high. 2, vacuum nitrogen-filled packaging, internal and external pressure balance (- 600~-700mmHg) air will not be able to gradually seep into the bag through the micropores of the bag to prevent premature corruption and deterioration of the fresh-keeping products. 3, vacuum nitrogen-filled packaging, the most suitable for fragile, afraid of extruded material packaging (such as flowers, chips, snack food, etc.), vacuum packaging can not be realized. 4. For some food or materials containing moisture, due to the differential pressure in the bag after vacuum packaging, the oil and water of the food or materials will seep out, which will affect the internal quality and appearance of the food or materials. 5. Some fried foods or fruit and vegetable chips are packed with vacuum nitrogen, which can effectively prevent food rancidity or extrusion and prolong the storage time.
