A tensioning device for spinning yarn transmission that automatically adjusts spinning yarn to prevent slack

Abstract

The invention relates to the technical field of needle textiles, and discloses a tensioning device for spun thread transmission that automatically adjusts the spun thread to prevent slack, including a pay-off machine. When the bobbin is outside, squeeze the block to make it rotate, and fix the bobbin to prevent the bobbin from being separated from the pay-off bobbin during the spinning of the bobbin. Spring, when the spun yarn is loose, the second turntable is moved down by the action of the outer spring, which is beneficial to the subsequent straightening of the spun yarn and increases the linkage between the structures. When the turntable moves up, the first turntable pulls the second turntable to move up through the spun thread, so that the spun thread is close to the outside of the second turntable, so that the spun thread is straightened again, avoiding the slack of the spun thread and the entanglement of the equipment. Prevents yarn slack and poor textile quality.

Description

technical field [0001] The invention relates to the technical field of needled textiles, in particular to a tensioning device for thread transmission that automatically adjusts the thread to prevent slack. Background technique [0002] Knitted textiles are processed and woven products, which are mainly divided into clothing textiles, decorative textiles and industrial products. Common knitted textiles include knitted garments, towels, gloves, blankets, etc., which permeate people's daily life. [0003] During the production process of knitted textiles, the yarn needs to be straightened and tightened so that the machine and equipment can weave. The loose yarn is easy to get off the pulley, entangled with each other or the machine equipment, causing the machine to malfunction and loosen. When the spun thread is spun, redundant coils will appear in the finished textile, which will affect the quality of the textile. Therefore, it is particularly important to keep the spun thread...

AI Technical Summary

Problems solved by technology

[0003] During the production process of knitted textiles, the yarn needs to be straightened and tightened so that the machine and equipment can weave. The loose yarn is easy to get off the pulley, entangled with each other or the machine equipment, causing the machine to malfunction and loosen. When the spun thread is spun, redundant coils will appear in the finished textile, which will affect the quality of the textile. Therefore, it is particularly important to keep the spun thread in a tight state during the weaving process. The existing tensioner is a kind of thread that makes the spun thread Tight maintenance equipment, but the commonly used tensioner cannot automatically tighten the spinning thread, and manual adjustment is required, which requires staff to watch on the sidelines, which is a waste of manpower, and when adjusting, in order to ensure the textile The quality needs to suspend the equipment, the operation is very inconvenient, and the work efficiency of the textile is greatly reduced

[0004] Aiming at the deficiencies of the prior art, the present invention provides a tensioning device for yarn transmission that automatically adjusts the yarn to prevent slack, which has the advantages of automatic stretching and straightening of the yarn and convenient operation, and solves the problems of inconvenient operation and manual adjustment , it can prevent the spinning of the bobbin from being separated from the pay-off cylinder during the spinning transmission, which will affect the progress of the spinning transmission, and automatically adjust the loose spinning yarn to straighten the spinning yarn again, avoiding the occurrence of loose spinning and equipment entanglement situation, it can also avoid the poor quality of textiles due to loose yarn, free your hands and make the operation more convenient
