AI Technical Summary

Technical Problem

In existing wet wipe folding mechanisms, the hard contact between the fabric and the folding plate leads to uneven friction, which can easily cause the fabric to fray, get stuck, or tear, affecting folding accuracy and finished product quality.

Method used

Multiple folding units are used, and the included angle of the folding teeth in each unit decreases sequentially. The teeth are turned outward to reduce friction, and sharp edges are eliminated by rounded transitions, so as to achieve forward and oblique contact between the fabric and the teeth.

Benefits of technology

It achieves uniform stress on the fabric, reduces frictional resistance, improves folding accuracy and production efficiency, protects thin fabrics, and ensures the quality of finished products.

Abstract

本发明涉及湿巾生产用折叠成型机构,涉及湿巾生产设备技术领域。该机构包括机架、导轨及多个折叠单元,每个折叠单元由相对设置的两块折叠板组成,折叠板内侧设有折叠成型齿段并形成过料缝;沿布料输送方向,各折叠单元的折叠成型齿段齿夹角依次减小,布料折叠角度逐步增大;折叠成型齿段沿布料输送方向弯折外翻,且外翻程度沿输送方向递增,使齿段与布料的接触夹角递减、摩擦力递减,以此平衡因齿夹角减小带来的摩擦力递增。本发明解决了现有技术中布料易损伤、张力不均、折叠精度差的问题,实现低摩擦、均匀受力折叠,提升湿巾成品良率与生产效率。
