[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 leads to cutting Tool intermittently cuts plastic film and degrades cut quality

Embodiment Construction
[0033] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following combination Figure 1 to Figure 7 , to further elaborate the present invention.
[0034] A plastic film cutting device, including a workbench 1, a clamping device 2 and a cutting device 3, the clamping device 2 is installed on the workbench 1, and the upper end surface of the workbench 1 is installed equidistantly from left to right Cutting device 3 is arranged.
[0035] The clamping device 2 includes an L-shaped vertical plate 21, a rotating shaft 22, a plastic film roll 23, a U-shaped clamping plate 24, and a clamping column 25. The L-shaped vertical plate 21 is symmetrically installed on the left end surface of the workbench 1. A rotating shaft 22 is installed between the vertical plates 21 through a sliding fit, and a plastic film roll 23 is installed on the rotating shaft 22. The front and rear ends of the U-shaped clamping...

Abstract
The invention relates to a plastic film cutting device. The plastic film cutting device comprises a working table, a clamping device and cutting devices, wherein the clamping device is arranged on theworking table; and the cutting devices are equidistantly arranged on the upper end surface of the working table from left to right. According to the plastic film cutting device and a cutting processing method, a plastic film is cut by adopting the design concept of multiple clamping, so that the stability of the entire plastic film is improved, the entire plastic film is in a non-relaxed state, and furthermore, the precision and efficiency of plastic film cutting are improved; and meanwhile, a pre-cutting structure and a cutting structure are combined for cutting 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), ...
