AI Technical Summary

Technical Problem

Existing winding devices are prone to deviation when winding cast films of different widths and cannot effectively clamp and limit their movement, resulting in limited stability and applicability.

Method used

An adjustment structure and an auxiliary structure were designed. The adjustment structure can be adjusted by adjusting the distance between the adjustment ring and the baffle to accommodate membrane rolls of different widths. The auxiliary structure can achieve automatic clamping and locking through a servo motor and gear system to ensure the stability of the membrane roll.

Benefits of technology

This improves the applicability of the winding device to film rolls of different widths, prevents film rolls from falling off, and enhances the stability and safety after winding.

Abstract

This utility model relates to the field of winding devices, and more particularly to a winding device for high-speed production of cast film. It includes a support frame, a support base fixedly connected to the upper surface of the support frame, a drive motor fixedly connected to one side of the support base, a drive shaft fixedly connected to the output end of the drive motor, a baffle fixedly connected to one end of the drive shaft, and a winding roller fixedly connected to the side of the baffle away from the drive shaft. The arc surface of the winding roller is provided with an adjustment structure, which includes an adjustment ring. The inner wall of the adjustment ring is threadedly connected to the arc surface of the winding roller. The high-speed production casting film winding device provided by this utility model allows for adjustment of the distance between the adjustment ring and the baffle, enabling the winding roller to wind plastic films of different widths, thus improving the applicability of the winding device. Furthermore, after the plastic film is wound, it can be clamped and limited to prevent the plastic film from falling off after winding.
