AI Technical Summary

Technical Problem

In existing rapier looms, the mechanical collision and motion positioning accuracy requirements between the rapier heads are high, resulting in complex equipment and high cost. In particular, it is difficult to achieve synchronous adjustment of the rapier belts on both sides in the production of three-dimensional multilayer fabrics.

Method used

The rapier belt head-end device that uses airflow to exchange weft yarns achieves non-contact exchange of weft yarns through high-pressure airflow and negative-pressure airflow via the yarn feeding head and yarn receiving head mechanism, reducing the requirements for the rapier belt movement accuracy and mechanical collision.

Benefits of technology

It achieves reliable and accurate weft yarn splicing, reduces equipment load and control difficulty, and is suitable for the production of wide-width fabrics and three-dimensional multilayer fabrics.

Abstract

本发明公开了一种气流交接纬纱的剑带头端装置,其包括一安装在送纱侧剑带头端随送纱侧一起运动的送纱头机构和一安装在接纱侧剑带头端随接纱侧剑带一起运动的接纱头机构。纬纱交接时:送纱侧,送纱头机构到达纬纱交接区后停止运动,并准备反向退剑,送纱侧电控夹纱器打开,送纱侧电磁阀脉冲式打开随即关闭,喷纱管中的纬纱在气流作用下向右喷出;接纱侧,接纱头机构到达纬纱交接区后停止运动,并准备反向退剑,接纱侧电控夹纱器打开,接纱侧电磁阀脉冲式打开随即关闭,在吸纱器前形成负压区,吸纳左侧送纱头机构喷出的纬纱,接纱侧电控夹纱器关闭夹持纬纱,完成纬纱交接。本发明的引纬过程中不会出现剑头之间的机械碰撞,且可降低运动定位精度。
