Sleeve; the advantages of the present invention: the distance between the left baffle and the right baffle is adjusted by the screw, which can adapt to the winding problem caused by different production volumes, and reduces the work caused by the disassembly of the original winding device when it is fully loaded The strength and danger reduce the production cost caused by the original need for multiple winding devices for winding. The discharge of the rubber track is controlled by the guide roller on the pin shaft between the left baffle and the right baffle. When discharging, the rubber track can be controlled to discharge smoothly through the guide bushing and guide roller provided on the baffle, which reduces the vibration of the discharging tray during discharging.
