When the spare winding roller 30 moves to the top of the lifting plate 52 with the belt 27, the belt 27 stops rotating, and the cylinder 32 is started to drive the lifting plate 52 to move upward, so that the support grooves 34 at both ends of the lifting plate 52 support the winding roller 30, and then the winding roller 30 is lifted to the winding station for winding the film;

[0038] The clamping structure includes a driving rod 37 that movably passes through the axial through hole of the fixed plate 36, and a plurality of limit strips 38 are connected to the driving rod 37 along its length direction.

When the lifting plate 52 moves up to lift the winding roller 30, it drives the penetration frame 49 to slide upward in the guide groove 50. The guiding effect of the guide groove 50 on the penetration frame 49 can drive the two penetration plates 46 to move toward each other on the lifting plate 52, thereby pushing the driving rod 37 to move on the lifting plate 52, and then automatically tightening and fixing the winding roller 30;

The second gear 56 is meshed and connected with the first gear 55. When the winding roller 30, which is tightly fixed, moves up to the winding station, the second motor 54 can be started, and the winding roller 30 is automatically driven to rotate through the first gear 55 and the second gear 56 to perform the winding work.

[0041] The implementation principle of a film forming and winding device according to an embodiment of the present invention is as follows: first, one end of the film to be wound is passed through between the two clamping strips 13, and the electric telescopic rod 7 is started to drive the moving plate 8 and the moving block 10 to move as a whole toward the side away from the supporting roller 4, and the two clamping strips 13 can be driven to move toward the side close to each other by sliding one end of the insertion rod 15 at the right end of the driving groove 16 to clamp one end of the film, so that when the moving block 10 moves, one end of the film can be automatically pulled to move, and when the moving block 10 moves to the extrusion plate 23, the extrusion block 12 on the first slider 11 pushes the extrusion plate 23, thereby pushing open the two groups of extrusion rollers 22, and automatically driving the film from the two groups of extrusion rollers. When the moving block 10 moves out from the squeezing plate 23, the elastic force of the first spring 19 is used to drive the two groups of squeezing rollers 22 to move in opposite directions and press against the upper and lower sides of the film, so that when the film is rolled up, the rolling is smoother and the rolling quality is improved. When the moving block 10 moves to the left end position close to the driving groove 16, the first motor 26 is started to drive the rotating rod 25 and the belt 27 to rotate as a whole on the fixed frame 24, and then the spare winding rollers 30 placed on the two adjacent support seats 29 are sent to the position just above the lifting plate 52, and the belt 27 stops rotating. Then the cylinder 32 on the U-shaped seat 31 can be started to drive the lifting plate 52 to move upward, and the lifting plate 52 at both ends can be used. The support groove 34 supports and lifts the winding roller 30. At the same time, the upward movement of the lifting plate 52 drives the penetration frame 49 to slide upward in the guide groove 50, and drives the two penetration plates 46 on the lifting plate 52 to move toward the side close to each other, thereby pushing the two driving rods 37 to move toward the side close to each other on the fixed plate 36, to push the clamping block 45 at one end of the moving handle 44 to be inserted into the winding roller 30, and use the rolling of the roller 42 on the fixed bar 43 to push the clamping block 45 to move and press against the inner wall of the winding roller 30, and fix the lifted winding roller 30 on the lifting plate 52. When the lifting plate 52 moves up to the bottom of the film, the winding roller 30 continues to move up, so that the film sticks tightly to the winding roller 3 0, and then start the second motor 54, and drive the winding roller 30 to rotate through the first gear 55 and the second gear 56. At the same time, the electric telescopic rod 7 continues to drive the moving block 10 to move, and utilizes the sliding of one end of the insertion rod 15 in the inclined section at the left end of the driving groove 16 to drive the two clamping strips 13 to move in the direction away from each other, so that when the winding roller 30 rotates, the clamping strip 13 automatically loosens the film, so that the rotating winding roller 30 can smoothly wind up the film. When the film is wound, the winding roller 30 stops rotating, and the cylinder 32 drives the winding roller 30 to move down and re-place it on the support seat 29. Finally, the belt 27 continues to rotate to transport the winding roller 30 after the wound film, and the film winding work can be completed.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
