A kind of plastic film cutting device and cutting processing method

Abstract

The invention relates to a plastic film cutting device, comprising a workbench, a clamping device and a cutting device. The clamping device is installed on the workbench, and a cutting device is installed equidistantly from left to right on the upper end of the workbench. Device, a plastic film cutting device and a cutting processing method provided by the present invention adopt the design concept of multiple clamping to cut the plastic film, improve the overall stability of the plastic film and make the plastic film as a whole in a non-relaxed state, Furthermore, the precision and efficiency of plastic film cutting are improved, and at the same time, the combination of pre-cutting and cutting structures is used to cut the plastic film, so as to improve the quality of plastic film cutting.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a plastic film cutting device and a cutting processing method. Background technique [0002] Plastic film refers to a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging, and used as a coating layer, which is durable, waterproof, light, easy to shape, Insulation and other advantages, but can not be naturally decomposed is one of the major disadvantages, plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, has been widely used in food, medicine, chemical industry, etc. Among them, food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging, etc. Commonly used plastic films include polyethylene (PE), polyvinyl chloride (PVC), ...

AI Technical Summary

Problems solved by technology

[0003] (1) The plastic film in a relatively loose state tends to cause the cutting tool to get stuck. The plastic film cannot be cut in one step, and the cutting incision is prone to wrinkles and shrinkage, which causes the cut plastic film to fail to meet the forming requirements. Processing requirements, at the same time, the degree of tension at the middle and outer ends of the plastic film is different, which leads to different states of the cutting fracture;

[0004] (2) During the cutting process of the plastic film, it is easy to shift on the workbench, and the plastic film is prone to move with the cutting tool, that is, the two ends of the plastic film shrink inward to form a wrinkled state, which in turn leads to cutting Tool intermittently cuts plastic film and degrades cut quality
