Plastic film production and manufacturing slitting machine and processing process

Abstract

The invention relates to a plastic film production and manufacturing slitting machine and a processing process. The film production and manufacturing slitting machine comprises a bottom frame, a placing mechanism and a clamping and cutting mechanism. The film production and manufacturing slitting machine and the processing process can solve the following problems existing in the slitting process of plastic films that a, during conventional cutting, a plastic film is typically cut by a common cutting tool, incomplete notches may exist, and the using effect is therefore poor; b, after slitting,because the cut plastic film retracts due to inertia, the effect of clamping the plastic film on two sides of a cutter is poor, the film may be torn, and the process flow is affected; and c, the lengths of plastic film rollers differ due to different width specifications of the plastic films, plastic films of one specification correspond to one supporting rack with regard to traditional equipment,and supporting racks of different specifications need to be switched when the plastic films of different specifications need to be placed, and the process flow is complicated.

Description

technical field [0001] The invention relates to the field of plastic film processing, in particular to a plastic film production and cutting machine and processing technology. Background technique [0002] Plastic film is produced by polyvinyl chloride, polyethylene and other resins through thermal melting and other processes. It is widely used in food, medicine, chemical industry and other fields. With the emergence of various new materials, new equipment and new processes, the promotion of This plastic film is developing in the direction of diversified and specialized composite films. These products have brought great convenience to people's production and life. The effect is the best. [0003] At present, the following problems exist in the slitting process of plastic films: a. In the traditional cutting process, ordinary cutting tools are usually used to cut plastic films, which may cause incomplete cuts, resulting in poor use effects; b. After slitting, since the plas...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a plastic film production and manufacturing slitting machine, which can solve the following problems in the plastic film slitting process: a. In the traditional cutting process, ordinary cutting tools are usually used to cut the plastic film, and there may be The problem of incomplete incision leads to poor use effect. After slitting, the plastic film will pull back due to inertia after cutting. The clamping effect of the plastic film on both sides of the cutting tool is not good, causing the film to appear The conditions such as tearing will affect the process flow. c Because the plastic film width specifications are different, the corresponding plastic film roll lengths are also different. In traditional equipment, one specification of plastic film corresponds to one support frame. When placing, frequent support frames of different specifications are required, and the process is more complicated
