Support shafts are symmetrically arranged on the frames at both sides below the turntable, and support wheels are arranged on the support shafts, one of which is driven to rotate by the winding motor. A limit rod connected to the frame for sliding connection is also arranged on the frame, a limit block is fixed on the end of the limit rod, a limit wheel is also arranged on the limit block, a spring is also arranged between the limit block and the frame, a synchronous belt is also arranged on one side of the frame, and the synchronous belt passes around the two supporting wheels and the limit wheel in sequence.

The support wheel is driven to rotate by the winding motor, and the synchronous belt rotates with the support wheel, and the turntable is driven to rotate by the rotating motor. The synchronous wheel of a winding shaft on the turntable reaches the synchronous belt position and meshes with the synchronous belt. When the synchronous belt rotates, the winding shaft rotates, and the starting end of the formed plastic film is transported to the winding shaft at the synchronous belt position. The plastic film is wound by the rotation of the winding shaft. After a certain amount of plastic film is wound on the winding shaft, the turntable is driven to rotate a certain angle by the rotating motor. The next synchronous wheel on the turntable reaches the synchronous belt position, and the electric telescopic rod is started, the electric telescopic rod is extended, the cutter rises, and the cutter The plastic film is cut off and the cut plastic film is covered on the reel at the synchronous belt position again, and the plastic film is reeled up by the reel at the synchronous belt position again, and the film roll with a certain amount of plastic film reeled up is taken down, and the cycle operation is carried out, and the synchronous belt is driven to rotate by the reeling motor to drive the corresponding reeling shaft to rotate, and the plastic film is reeled up. Only one reeling motor is required to drive the reeling shaft to rotate and continuously reel the plastic film. The device has low cost and is suitable for promotion. The synchronous belt is tightened by pushing the limit block downward by the spring, so that the synchronous belt can stably drive the synchronous wheel to rotate.

[0007] Preferably, two guide shafts are fixed on the frame, and guide rollers are arranged on the guide shafts. A positioning shaft is fixed on the frame between the two guide shafts, and positioning plates rotatably connected to the positioning shafts are symmetrically arranged on both sides of the positioning shaft. A limiting shaft is fixed between the two positioning plates, and limiting rollers are arranged on the limiting shaft. After the formed plastic film passes over the two guide rollers, the limiting rollers press the plastic film downward to tighten the plastic film, and the plastic film is rolled up after being tightened, so as to ensure the quality of the rolled plastic film.

[0008] Preferably, the positioning shaft is also provided with a torsion spring, one end of which is fixed to the positioning shaft, and the other end of which is fixed to one of the positioning plates. The positioning plate is driven to rotate by the torsion spring to increase the downward pressure of the limiting roller position, thereby ensuring that the plastic film is tightened.

[0009] Preferably, a positioning motor is fixed on the frame below the positioning shaft, and a positioning rod is fixed on the output end of the positioning motor. When the plastic film is cut, the positioning rod is driven to rotate by the positioning motor, and the end of the positioning rod contacts the positioning plate and pushes the positioning plate to rotate around the positioning shaft, so as to prevent the limiting roller from pressing down and pulling the plastic film after the plastic film is cut, so that the plastic film cannot cover the winding shaft at the synchronous belt position.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] The winding motor drives the synchronous belt to rotate, thereby driving the corresponding winding shaft to rotate and winding the plastic film. Only one winding motor is required to drive the winding shaft to rotate and continuously wind the plastic film. The device has low cost and is suitable for promotion. The spring pushes the limit block downward to tighten the synchronous belt, so that the synchronous belt can stably drive the synchronous wheel to rotate. BRIEF DESCRIPTION OF THE DRAWINGS
