[0032] In this embodiment, rotating the threaded ring 17 causes the upper top plate 18 to move. The upper top plate 18 rotates and pushes the receiving top plate 19. The receiving top plate 19 causes the outer moving ring 20 to move longitudinally.

Adjustment holes 26 are symmetrically opened on the film-coating platform 24, and multiple sets of adjustment holes 26 are provided. One end of the snapping tube 9 is installed at the bottom of the adjustment hole 26. Pressing block 11... A pressing spring 27 is installed at the bottom, and one end of the pressing spring 27 is connected to the limiting plate 25. The pressing rod 10 slides longitudinally on the limiting plate 25. The limiting plate 25 can help limit the extension length of the film body.

An outer retaining ring 28 is installed on the side wall of the clamping tube 9, and a return spring 29 is installed at the bottom of the outer retaining ring 28. The other end of the return spring 29 is connected to the outer moving ring 20. A mating ring 30 is installed on the mating rod 12, and one end of the top plate can be embedded in the rubber ring to fix the mating rod 12 and the pressing rod 10 inside the clamping tube 9.

[0034] More specifically, the membrane body is installed on the coating shaft 22. The membrane body passes through the tension adjustment shaft 23 to ensure appropriate tension. The position of the clamping tube 9 is adjusted through the adjustment hole 26, and the position of the limiting plate 25 is adjusted to control the extension length of the membrane body. The pressing rod 10 is quickly clamped to the clamping tube 9 through the limiting plate 25 and the coating platform 24.

The mating ring 30 and the rubber ring cooperate to fix the mating rod 12 and the pressing rod 10 inside the clamping tube 9.

[0035] In summary, when the overall equipment is in use or running: when the clamping and cutting mechanism needs to be operated, firstly, the clamping cylinder 2 drives the clamping plate 3 to move downward to clamp the membrane body, the drive motor 4 starts, drives the lead screw 5 to rotate, the rotation of the lead screw 5 drives the threaded block 6 to move horizontally, the cutting blade 8 at the top of the threaded block 6 slides in the cutting groove 7, and the cutting blade 8 cuts the clamped membrane body.

[0036] When the limiting snap-fit ​​mechanism is in operation, the limiting plate 25 can be quickly installed, disassembled and adjusted on the film-coating platform 24. The user uses the pressing block 11 to drive the pressing rod 10 and the cooperating rod 12 to move. When the pressing block 11 is pressed down, the snap-fit ​​auxiliary mechanism is used at the same time to make the inclined push block 14 on the slope block 13 slide in a direction. The tightening spring 15 provides a lateral tightening force between the nail plate 16 and the inclined push block 14 to fix the cooperating rod 12 and the snap-fit ​​tube 9. By different cooperation between the pressing rod 10 and the adjustment groove, the limiting plate 25 can be fixed in different positions.

[0037] When the auxiliary locking mechanism is in operation, rotating the threaded ring 17 moves the upper top plate 18. The upper top plate 18 rotates and pushes the receiving top plate 19. The receiving top plate 19 drives the outer moving ring 20 to move longitudinally. The outer moving ring 20 is linked with the inner moving ring 21, causing the inner moving ring 21 to slide on the inner wall of the locking pipe 9. The inner moving ring 21 cooperates with the inclined push block 14 to slide, causing the inclined push block 14 to move directionally on the slope block 13, further enhancing the locking effect.

[0038] The membrane body is installed on the coating shaft 22. The membrane body passes through the tension adjustment shaft 23 to ensure appropriate tension. The position of the clamping tube 9 is adjusted through the adjustment hole 26. The position of the limiting plate 25 is adjusted to control the extension length of the membrane body. The pressing rod 10 is quickly clamped to the clamping tube 9 through the limiting plate 25 and the coating platform 24. The clamping cylinder 2 is activated, and the clamping plate 3 clamps the membrane body. The drive motor 4 drives the cutting blade 8 to perform the cutting operation.
