The top of the sliding rod 605 is fixedly connected with a limit plate 608, and the top of the spring 606 is fixedly connected to the bottom of the limit plate 608, and the bottom of the spring 606 is fixedly connected to the top of the fixing plate 604. The bottoms of the two sliding rods 605 on the same side are fixedly connected with a pressing plate 607. The stabilizing component includes a slide groove 7, which is symmetrically opened inside the support frame 5, and a lifting rod 8 is fixedly connected inside the slide groove 7, and a slider 9 is slidably connected to the outer side of the lifting rod 8, and the two sliders 9 are fixedly connected to the mounting frame 602.

[0023] In the above technical solution, considering the lack of a pressing mechanism for the composite film, during the film cutting process, the film may be offset due to its own elasticity, and the composite film cannot be accurately cut, resulting in a waste of the composite film. In order to solve this problem, the specific operations are as follows:

[0024] Reference Figure 1 - Figure 4 In a preferred embodiment, when it is necessary to intercept the composite film, the staff starts the cylinder 601, and the output end of the cylinder 601 drives the film cutting knife 603 to move downward. During the movement, the pressing plate 607 presses the composite film on the top of the supporting seat 10, and the sliding rod 605 slides upward inside the fixed plate 604, and the spring 606 is stretched. As the film cutting knife 603 continues to move downward, the composite film is cut off. Through the provided film cutting mechanism 6, when intercepting the composite film, the composite film located on both sides of the film cutting knife 603 can be pressed on the top of the supporting seat 10 first, ensuring that the film cutting knife 603 will not cause the film cutting to deviate due to the elasticity of the film itself when cutting the composite film, and the composite film can be accurately intercepted, avoiding the waste of the composite film. The structure is simple and the practicability is strong.

[0025] Reference Figure 1 - Figure 4In a preferred embodiment, a support seat 10 is fixedly connected to the top of the operating table 1 and below the film cutting knife 603, and an avoidance groove 11 is provided on the top of the support seat 10. Rubber pads 12 are fixedly connected to the bottoms of the two pressing plates 607. The avoidance groove 11 is set in a V shape. A controller 13 is fixedly connected to the outside of the support frame 5, and the cylinder 601 is electrically connected to the controller 13. The support seat 10 and the avoidance groove 11 are provided to facilitate the cutting of the composite film and make the cutting of the composite film more accurate. The rubber pad 12 can increase the friction force and make the composite film pressed more stably. The controller 13 is provided to facilitate the staff to control the opening and closing of the cylinder 601, and the operation is easier.

[0026] Working principle: In actual use, the composite film is wound by the conveying roller 3 and the winding roller 4. When the composite film passes between the supporting seat 10 and the film cutting mechanism 6, when it is necessary to cut the composite film, the staff starts the cylinder 601, and the output end of the cylinder 601 drives the film cutting knife 603 to move downward. During the movement, the pressing plate 607 presses the composite film on the top of the supporting seat 10, and the sliding rod 605 slides upward inside the fixed plate 604, and the spring 606 is stretched. As the film cutting knife 603 continues to move downward, the film cutting knife 603 enters the inside of the avoidance groove 11 and performs a cutting operation on the composite film. At this point, the staff has completed the cutting work of the composite film.

[0027] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution.
