A method to solve the problem of stacked yarns in the production of polyester filaments

Abstract

The invention relates to a method for solving the problem of overlapping yarns in the production of polyester filaments. The core point of the method is to change the length of the threaded hole on the gland of the yarn grabber. The specific method is to change the threaded hole that plays a role in positioning on the gland of the wire grabber from a round hole whose position cannot be adjusted to a long hole whose position can be adjusted freely (the direction of the long hole is the same as the length direction of the wire grabber), and then through Adjust the position of the gripper cover on the forming plate of the winding machine, so as to change the length of the gripper sliding in the slideway and shorten the time from the unwinding action to the return of the gripper to its original position, and finally meet the requirements of the gripper on the winding machine. When returning to the original position, the technical requirement of not performing the wire grabbing action at the same time enables the wire grabber to coordinate with other head-up movements of the winding machine when each action is executed. The invention has the advantages of simple transformation means and remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a method for solving the problem of overlapping yarns in the production of polyester filaments. After the method is adopted, the number of overlapping yarns produced in the production process of polyester filaments is greatly reduced, so that the product is broken during the winding process. The sharp reduction in the number of ends finally ensured the smooth progress of polyester filament production, which belongs to the technical field of chemical fiber production. Background technique [0002] Lamination refers to the coiled end surface of the winding bobbin that is higher than other winding parts. It not only affects the unevenness of the dryness and the uniformity of dyeing, but also makes it difficult to unwind, and in severe cases, it will also cause the winding bobbin to be damaged. The edge collapses and becomes waste silk. Laminated wire is a serious phenomenon of lapping, and its formation has very complicated reaso...

AI Technical Summary

Problems solved by technology

When the diameter of the tow at the position where the stacked wires are generated increases to a certain extent, causing the winding pressure to reach a certain limit, the winding machine starts the automatic wire cutting program to cut off the wire head, resulting in the failure of the head raising operation

When the stacking phenomenon is serious, it will also cause the winding paper tube to burst or damage the expensive winding head

[0005] After observation, we found that the above-mentioned phenomenon of overlapping yarns during spinning head up and normal switching due to the limitation of the position of the yarn grabber slideway is the main reason for the unintentional increase in the number of broken ends in spinning production, accounting for the total number of broken ends. About 35% of it seriously affects the normal production of spinning and increases the product cost
