[0020] Example, refer to Figures 1-3 A drive device for a plastic circular loom includes a drive housing 1 and a drive shaft 3 disposed outside the drive housing 1. A rotating shaft 8 is rotatably connected inside the drive housing 1. A forward bevel gear 4 and a reverse bevel gear 7 are sleeved on the outer wall of the rotating shaft 8. A drive bevel gear 6 that meshes with the forward bevel gear 4 and the reverse bevel gear 7 is disposed inside the drive housing 1. A motor 5 is disposed on the side wall of the drive housing 1. The output end of the motor 5 is connected to the drive bevel gear 6. The device also includes a moving mechanism 2 disposed inside the drive housing 1. The moving mechanism 2 can adjust the position of the forward bevel gear 4 and the reverse bevel gear 7 to achieve dynamic meshing with the drive bevel gear 6 and can change the direction of power transmission.

A sleeve 202 is mounted on the other side wall of the drive disc 200. A support plate 201 is fitted onto the outer wall of the sleeve 202. The bottom of the support plate 201 is connected to the bottom of the drive housing 1. Under the action of the support plate 201, the sleeve 202 can be supported, thereby ensuring the stability of rotation. A movable rod 203 is slidably mounted inside the sleeve 202. One end of the movable rod 203 is equipped with a connecting plate 204. One end of the rotating shaft 8 is connected to the connecting plate 204. The four side walls are connected. A movable plate 208 is sleeved on the outer wall of the rotating shaft 8. A sliding rod 207 is movably inserted through the side wall of the movable plate 208.
