When the broken thread position reaches the opening area in the middle of the guide tube, the electric telescopic rod drives the blade heated by the heater to cut the yarn in the guide tube. The broken ends of the yarn are heated and stick together to prevent the multiple strands of the broken ends from collapsing. When the blade returns upward, the spring rod pushes the protective block to close to the blade to scrape off the sticky thread ends, so that the thread ends continue to move to the right in the guide tube driven by the guide wheel. No manual operation is required, which protects the safety of personnel.

[0015] 2. The utility model allows the thread end to fall to the right after passing through the through hole of the slider, and the thread end is dropped between the two rods of the winding frame by means of the extension tube on the slider. After reaching a certain length, the motor 2 drives the winding frame to rotate through the engaging piece, and the winding frame winds up the yarn. After the winding is stable, the motor 1 drives the slider to move up and down in the guide rail through the lead screw, and the yarn is evenly wound onto the winding frame. After the next wire breakage, the side door is opened to take out the winding frame, and the empty winding frame is installed on the top of the motor 2 through the engaging piece, which is convenient and quick.
