Rotation to realize the pay-off function; at the same time, the winding structure 5408 winds the rotor 1 5102 under the driving of the spool shaft to realize the winding function;

③ In the third step, after the winding is completed, the sensor transmits the signal to the stepper motor 1 5201. After the stepper motor 1 5201 receives the signal, it drives the rotor 1 5102 to rotate through the synchronous belt 2 5205, so that the rotor 1 5102 reaches a certain level. angle; repeat the second step;

④The fourth step, after the winding is completed, the proximity sensor at the positioning block 5208 transmits the signal to the up and down push cylinder 5301. When the up and down push cylinder 5301 receives the signal, the up and down push cylinder 5301 drives the sliding plate 5307 to move down. When the plate 5307 is moved to the thread trimming position, the fixing cylinder 5305 pushes the rotor fixing device 5303 to continue to move downward, thereby pressing the rotor; After the thread position is stopped, the thread trimming motor on the thread trimming device runs to realize the thread trimming function;

⑤The fifth step, after the thread trimming is completed, push the cylinder 5301 up and down to return, and the proximity sensor at the positioning block 5208 transmits the signal to the stepping motor 1 5101. After the stepping motor 1 5101 receives the signal, it drives the upper shelf 5112 to return to its position. then release the rotor;

⑥ In the sixth step, manually take out the rotor after the winding is completed, reset each mechanism, and complete the winding.
