AI Technical Summary

Technical Problem

Existing plastic film winding devices are difficult to effectively level, resulting in wrinkles, skewing, or undulations in the film during the winding process, which affects the winding quality.

Method used

A plastic film winding end-face flattening and trimming device is designed. Through the cooperation of a bidirectional motor, a flattening arc plate and an adapting arc plate in the trimming mechanism, the flattening arc plate is moved by a threaded rod and a limiting rod. Combined with the coating roller and coating box in the anti-adhesion mechanism, the film is flattened and anti-adhesion treatment is achieved.

Benefits of technology

It achieves uniform flattening of the film, reduces wrinkles, ensures good winding effect, and prevents impurities from adhering to the film surface during the winding process, thus improving film quality.

Abstract

This utility model discloses a plastic film winding end face flattening and trimming device, relating to the field of plastic film winding technology. The utility model includes a base plate, a conveyor frame fixedly connected to the top of the base plate, a winding frame disposed on the top of the base plate, a winding roller disposed inside the winding frame, and a trimming mechanism disposed on the top of the base plate. Through the cooperation of components such as the bidirectional motor, the leveling arc plate, and the adapting arc plate of the trimming mechanism, when the film is conveyed from the conveyor frame to the winding frame, the bidirectional motor is activated to drive the threaded rod to rotate, which in turn drives the leveling arc plate to move through the limiting rod and the threaded sleeve, leveling the film. As the winding amount increases, the adapting arc plate contracts through an adjusting spring to ensure that the leveling arc plate is in contact with the film surface. This design achieves the effect of leveling and trimming the plastic film during winding, ensuring uniform flattening of the film, improving the winding effect, and reducing film wrinkles.
