[0002] Yarn is a textile product with a certain fineness processed from various textile fibers. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn and continuous filament yarn. The production of yarn generally includes impurity removal, opening, combing, drafting, twisting and winding operations. The winding operation is to wind the semi-finished product or finished product into a yarn tube for storage, transportation and processing of the next process. One of the steps in the yarn production process is to wind the semi-finished product or finished product into a yarn tube for storage, transportation and processing of the next process. A yarn processing wire release device is needed, but the existing yarn release device still has certain problems when used:

[0003] For example, a yarn processing wire releaser with the publication number CN114291652A has a technical solution as follows: it includes a box, a groove is provided on the top outer wall of the box, a vertically arranged guide seat is fixedly connected to the inner wall at the bottom of the groove, a slide is provided on the outer wall on one side of the guide seat, a winding assembly equidistantly distributed is slidably connected to the inner wall on one side of the slide, a rectangular hole is provided on the outer wall on one side of the guide seat, and a first gear is rotatably connected to the inner wall at the bottom of the rectangular hole. A yarn processing wire releaser provided by the present invention can be turned on by turning on the switch of the electromagnet, so that the electromagnet adsorbs the sleeve rod to descend, and the yarn is driven to descend through the guide wheel on the sleeve rod, so that the yarn passes through two adjacent connecting rings, and the rubber block on the fixing groove of the connecting ring is used to fix the yarn, so that the yarn and the yarn roller to be wound are fixed, but the existing yarn releaser will cause the yarn to break during the winding process according to the different strengths of the toughness of the line. If the broken line cannot be detected after the break, the production time is wasted to continue working, thereby reducing the production efficiency.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.
