A film unwinding automatic cutting device and film automatic unwinding equipment

Abstract

The invention discloses an automatic cutting device for film unwinding, which includes a cutter mechanism and a first power device that drives the cutter mechanism to move up and down along the Z-axis direction and translates along the Y-axis direction. The cutter mechanism includes a support plate and is arranged on The upper sprocket on the upper part of the support plate, the lower sprocket arranged on the lower part of the support plate, and the chain saws arranged on the upper and lower sprockets, the support plate can be driven by the first power device along the Z-axis direction and along the Y-axis Direction translation. The invention also discloses an automatic film unloading device, which includes an automatic unwinding machine and the above-mentioned automatic cutting device. The invention can realize automatic cutting, automatic winding and automatic storage of the film, has a high degree of intelligence, saves manpower, and reduces labor costs.

Description

technical field [0001] The invention belongs to the technical field of film manufacturing, and in particular relates to an automatic cutting device for film unloading and automatic film unloading equipment. Background technique [0002] An important link in the unloading of the film is that the film needs to be cut manually when the station is changed. This method is labor-intensive and unsafe, and restricts the realization of complete automation of the unloading. [0003] At present, some rudimentary automatic cutting systems have appeared on the market. For example, the patent application with the application number 201410625799.3 discloses a plastic film forming and processing equipment, which includes a cutting frame, a transmission device and a flattening device. The inner side of the block is provided with a slide rail, on which a slide block is slidably arranged, the slide block is connected through a connecting rod, a heating device is provided at the lower end of t...

AI Technical Summary

Problems solved by technology

This kind of cutting device has the following disadvantages in the actual application process: when the generated film is thick, its cutting effect is greatly reduced, and it is even difficult to cut off in time

[0004] In addition, there is also a device on the market that is equipped with dynamic and static cutters that cooperate with each other to realize film cutting. With the extension of use time, due to the mechanical deformation of the cutter, adjustment errors and film belt Static electricity often causes quality problems such as continuous cutting, wire drawing and tailing of the cutting section, which greatly reduces the cutting efficiency and seriously affects the quality of the finished product

[0005] Existing film production, especially in the unwinding part of the film, has the problem of low automation. Manual participation in most of the unloading process, the size of the film roll diameter, the movement of the roll station, film cutting and the movement of the roll Most of them are done manually, which not only increases the labor intensity, reduces the production efficiency, but also greatly increases the manufacturing cost of the enterprise.
