AI Technical Summary

Technical Problem

In the existing film stretching process, the pressure rollers that are thick in the middle and thin at both ends cause longitudinal indentations or textures on the film surface, affecting the appearance quality and optical performance.

Method used

Connecting rings are set at both ends of the pressure roller, and non-woven fabric is sleeved on the pressure roller surface to soften the pressure roller surface. The non-woven fabric is connected to the pressure roller by a locking mechanism, which facilitates replacement and avoids marks on the film during the stretching process.

Benefits of technology

It effectively avoids marks caused by the characteristics of the pressure roller during the stretching process of the film, improves the appearance quality and optical performance of the film, and facilitates the replacement and maintenance of nonwoven fabric.

Abstract

本实用新型公开了一种薄膜卷料装置，包括：框架以及滚动设置在框架内侧的压辊，压辊两端通过锁紧机构连接有连接环，两个连接环之间固定设置有无纺布，锁紧机构包括与连接环和压辊一侧固定连接的锁紧座、转动设置在锁紧座内侧的小半盘以及用于两个锁紧座连接固定的大半盘，锁紧机构分为两组，两组锁紧机构分别位于压辊的两端和两个连接环一侧，且每两个锁紧座通过小半盘配合使用。压辊两端所设置的连接环，能将无纺布套设在压辊外侧与其贴合，无纺布可使压辊表面柔软，从而，可以避免在对薄膜进行拉宽时，薄膜会因压辊中间粗两端细的特性拉出痕迹，同时无纺布通过两个连接环与压辊进行连接，方便工作人员对连接环拆卸，然后对无纺布进行更换。
