[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , a winding device for producing PVC film, comprising a workbench 1, a rotating assembly and a supporting assembly, the rotating assembly comprising a supporting plate 2, a motor 3, a turntable 4, an elastic member, a baffle 5, a spline 6 and a bearing assembly, the supporting plate 2 is provided with two groups symmetrically arranged on the workbench 1, the supporting plate 2 is provided with a turntable 4 at one end near the center of the workbench 1, the two ends of the elastic member are respectively connected to the center of the turntable 4 and the baffle 5, the baffle 5 is provided with a spline 6 at one end away from the support plate 2, a group of output ends of the motor 3 passes through the support plate 2 and is connected to the turntable 4, the bearing assembly comprises a winding roller 7, a connecting pipe 8 and a supporting ring 9, the winding roller 7 is symmetrically provided with a connecting pipe 8 on the left and right sides, the connecting pipe 8 is further provided with a keyway connected to the spline 6 at one end away from the winding roller 7, the winding roller 7 is symmetrically sleeved with the supporting ring 9 on the left and right sides, and the workbench 1 is also provided with a supporting assembly for supporting the connecting pipe 8.

[0024] The workbench 1 serves as the basic supporting structure of the entire winding device. The support assembly can stably support the load-bearing assembly. The staff squeezes the elastic part and rotates to adjust the load-bearing assembly. When the spline 6 is aligned with the keyway, the baffle 5 is released, and the elastic part pushes the baffle 5. The spline 6 of the baffle 5 is inserted into the keyway. The turntable 4 is rotatably connected to the support plate 2. The motor 3 adopts a servo motor 3 with stable control. The motor 3 drives the turntable 4 to rotate, and the elastic part drives the baffle 5 to rotate. The spline 6 is inserted into the connecting pipe 8 and then rotates the winding roller 7. The winding roller 7 is also provided with a support ring 9 for limiting the material.

[0025] During actual use, since the spline 6 cooperates with the elastic member to be plugged into the connecting pipe 8, it is easy to cause the load-bearing component to swing left and right during this transmission process. For this reason, the support component includes a skeleton 10, a roller seat 11 and a support roller 12. Two groups of symmetrically arranged skeletons 10 are provided on the workbench 1. The roller seats 11 are symmetrically provided at the front and rear ends of the two groups of skeletons 10. The support roller 12 is rotatably provided on the roller seat 11. The front and rear sides of the lower side of the connecting pipe 8 are in contact with the support roller 12. The connecting pipe 8 is also provided with two groups of guide rings 13 symmetrically arranged on the left and right sides of the support roller 12. The skeleton 10 drives the roller seat 11 to support the support roller 12, and the support roller 12 supports the connecting pipe 8. The guide ring 13 is in contact with the support roller 12 to prevent the load-bearing component from swinging left and right.

[0026] In this embodiment, the elastic member includes a spring 14 and a telescopic rod 15. The spring 14 is sleeved on the telescopic rod 15. Both ends of the spring 14 and the telescopic rod 15 are respectively connected to the turntable 4 and the baffle 5. The spring 14 facilitates the reciprocating movement of the baffle 5, and the telescopic rod 15 ensures that the baffle 5 with the spline 6 moves stably.

[0027] In actual use, if manual extrusion of the elastic member is used to assemble the load-bearing component, the operation is inconvenient. An unlocking member is further provided at one end of the skeleton 10 near the support plate 2. The unlocking member includes a propeller 16 and a U-shaped plate 17. The propeller 16 is embedded in the skeleton 10, and the output end of the propeller 16 is connected to the U-shaped plate 17. The groove of the U-shaped plate 17 is adapted to the connecting pipe 8. The propeller 16 adopts a corresponding rapid cylinder. When the load-bearing component is transferred, the propeller 16 drives the U-shaped plate 17 to squeeze the baffle 5, and the elastic member contracts. At this time, the guide ring 13 of the connecting pipe 8 is prevented from being on both sides of the corresponding support roller 12, and then the propeller 16 is reset. At this time, the elastic member naturally stretches, and the spline 6 presses against the connecting pipe 8. As the motor 3 rotates, the spline 6 is aligned with the keyway, and the load-bearing component can rotate accordingly.
