The rotating plate rotates under the action of the third drive motor connected to the reducer, and the limit post on the installation side plate rotates in the limit groove of the rotating plate to drive the entire rotating plate to rotate a certain angle. When the rotating plate is clockwise When rotating, the contact surface of the wire with the lower adjusting wheel when entering increases, and the contact surface with the wire wheel when going out increases, the wire is tightened at the entry position and the exit position, and the tightness of the wire is also adjusted. Under the action of the wire, it can ensure that the wire is kept in a tight state when it enters the winding machine, so as to prevent it from being wound loosely;

2. In this invention, a series of structures such as a fixed inner core, a buffer spring, a rubber pressure block, and a rubber layer are added to the inside of the upper adjusting wheel. The buffer spring is always kept in a compressed state under the action of the wire pressing the rubber layer, and the cylinder works. When the horizontal connecting rod and the lower adjusting wheel are driven downward as a whole, the entire wire is further tightened. At this time, if the speed of the equipment is slowed down to match the larger width of the stator, the wire will definitely loosen, even if the speed is adjusted.
