There are many types of packaging machinery, many classification methods. From different points of view there can be a variety of, according to the product state, there are liquid, block, bulk packaging machine; according to the role of packaging, there are inner packaging, outsourcing packaging machine; according to the packaging industry, there are food, daily chemical, textiles and other packaging machine; according to the packaging station, there is a single-station, multi-station packaging machine; according to the degree of automation, there is a semiautomatic, automatic packaging machine, etc..
There are many ways to categorize packaging machinery, a variety of classification methods have their own characteristics and scope of application, but have their limitations. From the point of view of the international packaging machinery in general, the more scientific classification method is to classify its main function, it can capture the essence of things. Its basic classification is as follows:
1, filling machine
Filling machine is the precise number of packaged goods into a variety of containers within the packaging machine. Its main categories are:
1) volumetric filling machine. Including measuring cup type, tube type, plunger type, material level type, screw type, timing type filling machine.
② weighing filling machine. Including intermittent weighing, continuous weighing, weighing - centrifugal centrifugal filling machine.
3 counting filling machine. Including single-piece counting type, multi-piece counting type filling machine.
2, sealing machine
Sealing machine is filled with packaging containers for the sealing of machinery, its main categories are:
① no sealing material sealing machine. Including hot-pressing type, cold-pressing type, welding type, insertion type, folding type sealing machine.
② sealing material sealing machine. Including spinning type, rolling type, crimping type, press type sealing machine.
3 auxiliary sealing material sealing machine. Including tape type, bonding type, pinning type, ligature type, sewing type sealing machine.
3, wrapping machine
Wrapping machine is a flexible packaging materials, all or part of the package will be wrapped up packaging machine. Its main types are:
①Whole wrapping type wrapping machine. Including twisting type, covering type, sticking type, seam type and other wrapping machines.
② half-wrapped wrapping machine. Including folding, shrinkage, stretching, winding and other wrapping machines.
4, multi-functional
This type of packaging machine has two or more functions. Its main categories are:
①Filling and sealing machine. It has two functions of filling and sealing.
② molding filling and sealing machine. It has a molding, filling, sealing three functions. The types of molding are bag molding, bottle molding, box molding, blister molding, melt molding and so on.
③Shaping filling and sealing machine. It has the function of molding, filling and sealing.
4 double-sided sealing machine. It can seal the top cover and bottom at the same time. When sealing the box, the box can be placed sideways or upright.
5, according to the tape sealing position and the number of classification
①I-type sealing machine. It is in the case of the top cover and the bottom of the outer folding seams with a tape sealing. This kind of sealing, operation is simple, but the sealing is poor.
② H-type sealing machine. It is based on the I-type sealing, that is, in the I-type sealing tape at both ends of the sealing two tapes, shaped like H, so called H-type. It can increase the box strength and sealing performance, but the cost is higher.
6, according to the degree of specialization classification
① General sealing machine. It can adjust certain institutions to change the size of the sealing machine to adapt to a variety of sizes and specifications of the box sealing. It has a wide range of adaptability, is a commonly used sealing machine.
②Specialized sealing machine. It can only seal a certain size of the box, sealing speed, suitable for high-volume sealing operations.
3 random sealing machine. It is in the specified size range, the relevant agencies can automatically change to adapt to different sizes of box sealing needs, is a high degree of automation sealing machine.
