[0055] Further referring to Figure 7 , the pressure roller structure 17-1 further comprises two groups of pressure roller mounting seats 17-1-4 slidably connected to the pressure roller shaft arm 17-1-5, and the two groups of pressure rollers 17-1-3 are rotatably connected to the two groups of pressure roller mounting seats 17-1-4, respectively. A through hole is formed in each pressure roller mounting seat 17-1-4, and a pressure roller adjusting rod 17-1-2 is arranged in the through hole. A rectangular locking groove 17-1-6 is formed on the pressure roller adjusting rod 17-1-2, and a right-angle locking groove 17-1-7 is formed on the pressure roller shaft arm 17-1-5 and can be clamped and matched with the rectangular locking groove 17-1-6. A pressure roller spring 17-1-1 is sleeved on the pressure roller adjusting rod 17-1-2, and a locking nut is screwed on the top of the pressure roller adjusting rod 17-1-2.

[0056] Before work, the spacing between the pressure wheels 17-1-3 is adjusted to match the width of the film, which facilitates the guiding and positioning of the processed film during winding, avoids deviation during film conveying, and improves the film collection of the winding structure, thereby improving the film conveying efficiency and cutting efficiency.

[0057] As shown in Figure 6 In this embodiment, the material pulling pressure plate structure 17-2 includes a position-adjustable rear adjusting rod 17-2-1 connected to the drum mounting frame 17-5, a position-adjustable rear pressure plate rod 17-2-2 connected to the rear adjusting rod 17-2-1, and a material pulling pressure plate 17-2-3 with elasticity mounted on the rear pressure plate rod 17-2-2. A strip-shaped hole extending along the length of the rear adjusting rod 17-2-1 is formed in the rear adjusting rod 17-2-1, and the rear adjusting rod 17-2-1 is connected to the drum mounting frame 17-5 by a bolt inserted into the strip-shaped hole. It should be noted that the material pulling pressure plate 17-2-3 can limit the position of the film product during conveying to prevent the film from bulging during conveying.

[0058] Working process:

[0059] During work, the film is conveyed by the feeding adjusting assembly 2. Before conveying, the material blocking sleeve structure 2-3 and the front material passing limiting structure 2-9 in the feeding adjusting assembly 2 are adjusted according to the width of the film, the rear material passing limiting structure 16-2 in the discharging limiting assembly 16 is adjusted, and the pressure wheel structure 17-1 in the material pulling assembly 17 is adjusted, so that the film product can be conveyed in a protective manner during conveying, avoiding the product from deviating and affecting the die cutting operation of the film. During the conveying of the film, the film can be limited and pressed by the feeding pressure plate structure 2-2 and the material pulling pressure plate structure 17-2 to prevent the film from bulging during conveying. During the conveying of the film, the lifting reduction motor 6-8 in the lifting driving assembly 6 can drive the driving eccentric wheel 6-5 to rotate, thereby driving the upper cutter 10 mounted on the adjusting mounting seat 14 to reciprocatingly move up and down, and cooperating with the lower cutter 12 mounted on the material collecting assembly 15, the film being conveyed can be die cut.

[0060] The cut film falls into the material collecting box 15-4 from the material falling opening formed in the lower cutter seat 11. When the film collected in the material collecting box 15-4 reaches a certain amount, the material collecting box 15-4 is taken out and replaced with an empty material collecting box 15-4. When the lower cutter seat 11 needs to be replaced, the horizontal moving motor 19-2 in the cutter seat horizontal moving assembly 19 is started to drive the horizontal moving screw 19-4 to rotate, thereby driving the moving base 15-1 to move along the horizontal moving guide rail 19-3 to the outside of the cutting position of the upper cutter 10, thereby facilitating the operator to replace the lower cutter seat 11 outside the film cutting position of the upper cutter 10, and improving the convenience and safety of the operation process.

[0061] The die-cut adhesive film is transmitted forward under the action of the rotating pulling roller 17-4 and the pressure roller structure 17-1, and then the die-cut adhesive film is transmitted to the winding device to complete the winding operation.
