[0002] A textile machine, also called a spinning machine, a loom, or a cotton spinning machine, is a loom driven by human power in ancient times. A textile machine is the full name for a tool that processes raw materials such as thread, silk, and hemp into threads and then weaves them into cloth.

[0003] In the existing textile machine detection and yarn feeding device, the yarn is released directly from the conveying shaft, so the yarn will swing left and right after being conveyed, making the yarn delivery unstable, and when the delivery is paused, the conveying motor will send out more yarn due to inertia. Under the combined effect of the two, when the yarn feeding is restarted, the yarn is prone to knotting, breaking, etc. due to insufficient yarn tension, making the yarn feeding device unstable.

At this time, the electric rod is started to push the upper fixed block and the lower fixed block downward, so that the yarn passing therethrough is also moved downward, and the yarn is re-tightened, so that the surface tension of the yarn is consistent with that before. When the yarn feeding is started again, all components are also returned to their positions, thereby improving the stability of the yarn feeding.
