There are many kinds of packaging machinery and many classification methods. From different angles, there are many kinds, according to the product state, there are liquid, block and granular packaging machines; According to the function of packaging, there are inner packaging and outer packaging machine; According to the packaging industry, there are food, daily chemical, textile and other packaging machinery; According to the packaging station, there are single-station and multi-station packaging machines; According to the degree of automation, there are semi-automatic and fully automatic packaging machines.
There are many classification methods of packaging machinery, each method has its own characteristics and scope of application, but it has its limitations. From the general situation of the world packaging machinery, a more scientific classification method is to classify according to its main functions, so as to grasp the essence of things. Its basic classification is as follows:
1, filler
Filling machine is a kind of packaging machine that packs 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 and timing filling machine.
② Weigh the filler. Including intermittent weighing, continuous weighing, weighing-centrifugal sub-loader, etc.
③ Counting filling machine. Including single-piece counting type and multi-piece counting type filling machines.
2, sealing machine
Sealing machine is a machine for sealing containers filled with packaging materials. Its main types are:
① Sealing machine without sealing material. Include hot pressing, cold pressing, welding, inserting and folding sealing machines.
② Sealing material sealing machine. Comprises a rotary sealing machine, a rolling sealing machine, a pressure sealing machine and a pressing sealing machine.
③ Sealing machine with auxiliary sealing material. Comprises a tape sealing machine, an adhesive sealing machine, a stapling sealing machine, a ligating sealing machine and a sewing sealing machine.
3, wrapping machine
Wrapping machine is a kind of packaging machinery that wraps all or part of packaging materials with flexible packaging materials. Its main types are:
① All-inclusive packaging machine. Including kinking, wrapping, body-fitting, sewing and other wrapping machines.
② Semi-package packaging machine. Include folding, shrink, stretching and winding packaging machine.
4. Multifunctional
This packaging machine has two or more functions. Its main types are:
① Filling and sealing machine. It has two functions: filling and sealing.
② Molding, filling and sealing machine. It has three functions: molding, filling and sealing. The types of molding include bag molding, bottle molding, box molding, plastic suction molding, melt molding and so on.
③ Setting, filling and sealing machine. It has the functions of setting, filling and sealing.
④ Double-sided sealing machine. It can seal the upper cover and the lower bottom. When sealing the box, the box can be placed horizontally or vertically.
5, according to the tape sealing position and quantity classification.
① Type I sealing machine. The outer folding seam of the upper cover and the lower bottom of the box are sealed with adhesive tape. This kind of sealing operation is simple, but the sealing performance is poor.
②H-type sealing machine. On the basis of I-type sealing, it is called H-type, that is, sealing two tapes at both ends of I-type sealing tape, which are similar in shape to H, can increase the strength and sealing performance of the box, but the cost is higher.
6, according to the degree of specialization.
① General sealing machine. Some mechanisms can be adjusted to change the relevant dimensions of the box sealing machine to adapt to the sealing of boxes with various sizes and specifications. Widely used, it is a widely used box sealing machine.
② Special sealing machine. Only boxes of a certain size can be sealed, and the sealing speed is fast, which is suitable for large-scale sealing operation.
③ Random sealing machine. Within the specified size range, the relevant mechanism can change automatically to meet the needs of sealing boxes with different sizes, and it is a highly automated box sealing machine.
