Classification of packaging
There are many types of packaging machinery and many classification methods. There are many types from different viewpoints. According to the product status, there are liquid, block, and bulk packaging machines; according to the packaging function, there are inner packaging and outsourcing packaging machines; according to the packaging industry, there are food and daily use Packaging machines for chemicals and textiles; according to packaging stations, 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 for packaging machinery. Each classification method has its own characteristics and scope of application, but all have their limitations. From the general situation of international packaging machinery, the more scientific classification method is to classify according to its main function, which can grasp the essence of things. The basic classification is as follows:
(1) Filling machine
The filling machine is a packaging machine that loads precise quantities of packaged products into various containers. The main types are: ① volumetric filling machine. Including measuring cup type, intubation type, plunger type, material level type, screw type, timing type filling machine. ②Weighing filling machine. Including intermittent weighing type, continuous weighing type, weighing-centrifugal equal fraction filling machines. ③Counting type filling machine. Including single-piece counting type and multi-piece counting type filling machines.
(2) Sealing machine
The sealing machine is a machine that seals the container filled with packaging. Its main types are: ①sealing machine without sealing material. Including hot pressing, cold pressing, fusion welding, plug-in, folding and other sealing machines. ②There is a sealing material sealing machine. Including rotary type, rolling type, crimping type, pressing type and other sealing machines. ③There is a sealing machine with auxiliary sealing material. Including tape type, adhesive type, nail type, ligation type, suture type and other sealing machines.
(3) Wrapping machine
Wrapping machine is a packaging machine that wraps all or part of the packaging with flexible packaging materials. The main types are: ①Full-wrap wrapping machine. Including twisting type, covering type, body type, seam type and other wrapping machines. ②Semi-wrapped wrapping machine. Including folding, shrinking, stretching, winding and other wrapping machines.
(4) Multifunctional packaging machine
This type of packaging machine has two or more functions. The main types are: ①filling and sealing machine. It has two functions of filling and sealing. ②Forming, filling and sealing machine. It has three functions: forming, filling and sealing. The types of molding include bag molding, bottle molding, box molding, blister molding, and melt molding. ③Shaped filling and sealing machine. It has the functions of shaping, filling and sealing. Forming method ④Double-sided carton sealing machine. It can seal both the upper cover and the lower bottom at the same time. When sealing, the box can be placed on its side or upright.
(3) Classified according to the location and number of tapes sealed
①Type I carton sealing machine. It is sealed with a piece of tape at the seam of the outer flap of the upper cover and the lower bottom of the box. This kind of sealing is simple to operate, but the sealing performance is poor. ②H-type sealing machine. It is based on the I-type sealing tape, that is, two tapes are sealed at both ends of the I-type sealing tape, and the shape is H, so it is called H-type. It can increase the strength and sealing performance of the box, but the cost is higher.
(4) Classified by degree of specialization
①Universal sealing machine. It can adjust certain mechanisms to change the relevant size of the sealing machine to adapt to the sealing of boxes of various sizes. It has a wide range of applications and is a universally used box sealing machine. ②Special sealing machine. It can only seal boxes of a certain size, and the sealing speed is fast, suitable for mass sealing operations. ③Random type sealing machine. It is within the specified size range, and various related organizations can automatically change to meet the needs of sealing boxes of different sizes. It is a highly automated box sealing machine.
