Wheel assembly comprises wheel one 53, wheel two 54. The first wheel is a running wheel, and the second wheel is a bearing. The bearing is suspended next to the rotating wheel by a cross bar. The direction moves to squeeze the spring, and the spring drives the cross bar and the bearing to conflict with the rotating wheel to compress the binding wire to realize the pre-tensioning of the binding wire. The structure is simple and practical.

Working principle of the present invention:

Step 1: The fixing member 12 is in conflict with the edge of the stator without coils or/and the side wall of the stator, so as to fix the stator.

Step 2: Limit the bushing to the copper coil of the stator through the clamping piece 112 .

Step 3: The clamping part 23 fits the end wall of the barrel 21 to clamp the binding wire protruding from the outlet pipe 71 .

Step 4: The crochet needle 61 moves up and down, forward and backward and rotates to wind the binding wire between the thread clamping mechanism 2 and the wire outlet barrel on the copper coil. When the crochet needle 61 hooks the thread, the moving binding thread drives the sleeve 42 to move upwards, so that the position sensor senses, and then the thread-feeding motor 51 is released.

Step 5: When the wire hook mechanism 6 stops running, the binding wire accumulates at the sleeve 42, so that the sleeve 42 falls freely under the action of gravity, so that the position sensing component 4 quickly resets, and then the motor stops paying off the wire in time.

Step 6: When a coil binding is completed, the clamping part 23 is separated from the end of the barrel 21, and the thread end is released.

Step 7: The clamping body 22 and the cylinder body 21 are close to the outlet pipe 71, and the binding wire protruding from the outlet pipe 71 is re-clamped, and then the clamping body 22 and the cylinder body 21 move backward, so that the blade of the blade part 24 is aligned with the bottom The binding lines of the coils conflict with each other, cut off the tail line of the previous binding coil, and carry out the binding line of the next wheel.
