A textile polyester thread bobbin

Abstract

The utility model discloses a kind of textile polyester thread winding drum, belong to textile production technical field, including winding drum body, the opening at both ends of winding drum body is equipped with cylinder wall by connecting assembly, the connecting assembly includes the connecting groove being opened at the opening at both ends of winding drum body, the inner wall of the connecting groove is equipped with positive thread, the inside fixed connection of the connecting groove has helical spring;The utility model, by the thread connection structure of reverse thread and positive thread, it is convenient for staff to quickly dismount and replace connecting pipe and cylinder wall, by replacing the installation state of the cylinder wall of different specifications or adjusting, the winding space of winding drum body can be flexibly changed, and then the winding length of winding drum body is improved;Meanwhile, the supporting effect of helical spring cooperation support baffle ring to connecting pipe can effectively eliminate the gap between reverse thread and positive thread, improve the tightness of both connections, avoid cylinder wall loose in winding process, ensure winding stability.
