Winding assembly for continuous foaming material

Abstract

The invention belongs to the technical field of foaming material production equipment, and particularly discloses a winding assembly for a continuous foaming material. The winding assembly comprises adeviation rectifying machine, a first tensioner, a traction machine, a second tensioner and a winding frame which are sequentially arranged. The first tensioner and / or the second tensioner comprise / comprises a floating roller and two guide rollers which are arranged on the two sides of the floating roller and further located above the floating roller. Drive parts are arranged at the two ends of the floating roller, and the floating roller can move up and down through the operation of the drive parts. By means of the winding assembly for the continuous foaming material, tension change and positional deviation caused by winding can be stably adjusted in time, winding can be completed without influencing shaping dimensional accuracy and the working efficiency is high.

Description

[0001] This application is a divisional application with application number 2020105716850, application date 2020.06.22, and invention name "a device for constant thickness of continuous foaming materials". technical field [0002] The invention belongs to the technical field of foaming material production equipment, and in particular relates to a continuous foaming material winding assembly. Background technique [0003] Sheet foaming refers to the process of heating a strip-shaped polymer material in a foaming furnace, and the foaming agent decomposes at high temperature to generate gas, fills the inside of the polymer material, and produces a foaming material with closed pores. In production, after the foaming is completed, the foaming material needs to be cooled and shaped by a cooling device, and then rolled directly or after some post-processing procedures (such as edge trimming, embossing, cutting, etc.) to obtain the finished product. In the above process, the cooling...

AI Technical Summary

Problems solved by technology

In the above process, the cooling and shaping process is particularly important, which determines the size deviation of the finished product, and there are many factors that affect the shaping effect, mainly in the following two aspects; one is the structural design of the cooling device itself, which directly reflects the precision level of the finished product size control. Cooling and shaping devices are mostly cooling rollers located outside the foaming furnace (such as CN105599210B, CN209111359U); the second is the effect of winding, because the sheet is relatively light and thin (usually only 2-3mm), the speed change during winding is easy to make it Changes in position and tension will affect the shaping effect and increase the size deviation of the finished product, especially in thickness. Foam materials usually need to be used on other boards. Once there is a large deviation in the thickness of different parts, it will directly affect other parts. The combination with the board will affect the quality and performance of the board

[0004] In order to improve the dimensional accuracy of the finished foam material, most of the existing methods start with the structural improvement of the cooling device, seldom considering the effect of winding, but even if the cooling device itself can control the dimensional accuracy of the material well, if the winding cannot be reduced or eliminated impact, it will cause the cooling device to fail to give full play to its precision control level; and once the winding stops (during roll change or affected by the follow-up process), it will not only have a great impact on the shaping effect, but also cause the entire production line to stop, seriously affecting work efficiency
