First, the servo motor 13 drives the bidirectional threaded screw 14 to rotate inside the track seat 12, so that the bidirectional threaded screw 14 drives the two mounting racks 1 to move toward each other through the moving block 11, so that the two TPU film tube placement trays 15 loosen the supported TPU film tube. During this process, the winding motor 16 drives the TPU film tube placement tray 15 to rotate slowly. When the opening on the TPU film tube placement tray 15 is downward, the supported TPU film tube will automatically fall from the inside of the TPU film tube placement tray 15, thereby realizing automatic unloading of the rolled TPU film tube;

[0023] Then the output end of the first electric push rod 21 is retracted, and the TPU film tube stored in the TPU film tube storage rack 2 will fall onto the TPU film tube placement plate 15, and then the output end of the first electric push rod 21 is extended to limit the position of the TPU film tube in the TPU film tube storage rack 2. When the opening of the TPU film tube placement plate 15 coincides with the TPU film tube, the TPU film tube will automatically fall into the opening of the TPU film tube placement plate 15, and then the servo motor 13 drives the bidirectional threaded screw 14 to rotate inside the track seat 12, so that the bidirectional threaded screw 14 drives the two mounting frames 1 to move relative to each other through the moving block 11, so that the two TPU film tube placement plates 15 support the TPU film tube, so that the TPU film tube on the winding device can be automatically loaded, which reduces the labor intensity of the operator when loading and unloading the TPU film tube, and improves the convenience of the winding device when loading and unloading the TPU film tube.
