PET film winding and slitting equipment

Abstract

The invention relates to the technical field of film cutting equipment, and discloses PET film winding and slitting equipment. The PET film winding and slitting equipment comprises a rolling shaft. Asupporting frame is movably connected to the bottom side wall of the rolling shaft. A rotating plate is movably connected to the bottom end of the supporting frame. A pull rod is connected to the bottom side of the rotating plate in a sliding mode, and a telescopic rod is fixedly connected to the side wall position of the pull rod. A telescopic plate penetrates through the side wall position of the telescopic rod. A movable shaft penetrates through the side end of the rolling shaft. In the rotating process of the rolling shaft, the side wall of the supporting frame can be driven to rotate, thebottom end of the supporting frame can sweep back and forth at the top end of the rotating plate, the bottom side of the rotating plate can sweep at the top end of the pull rod, the side wall of thetelescopic rod can be tilted outwards, and the side wall of the rotating plate can be conveniently supported to obliquely scrape when facing the side wall of a film; and enough supporting force is provided for the film, and the situation that the cutting speed is decreased due to the tension influence of the film in the cutting process can be avoided.

Description

technical field [0001] The invention relates to the technical field of film cutting equipment, in particular to a PET film winding and cutting equipment. Background technique [0002] PET film is a relatively comprehensive packaging film with excellent physical and mechanical properties, such as good transparency, gloss, good air tightness and fragrance retention. In addition, PET film also has excellent optical properties. Such as good transparency, low haze, high gloss, etc., so it is widely used in signage with reflective requirements and high-end aluminum plating and other products. [0003] In order to facilitate storage and transportation, PET film is generally manufactured into a roll-shaped finished product. During the production and processing process, the PET film needs to be wound and cut. The traditional PET film winding and cutting device has a relatively simple structure. During the process, the side walls of the PET film tend to be folded closer together, res...

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate storage and transportation, PET film is generally manufactured into a roll-shaped finished product. During the production and processing process, the PET film needs to be wound and cut. The traditional PET film winding and cutting device has a relatively simple structure. During the process, the side wall of the PET film is easy to fold, resulting in fold lines. During the cutting process, the tension of the side wall of the film is insufficient, which cannot guarantee smooth cutting, and will also affect the cutting effect.
