The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-4 As shown, the utility model proposes a limiting mechanism of a film cutting machine, including a base 1, a cutting knife 2 and a limiting assembly 3, the top wall of the base 1 is provided with a workbench 6, the bracket 4 is arranged on the workbench 6, the base 1 is provided with a bracket 4, the bracket 4 is provided with a slide 5, the cutting knife 2 is detachably arranged on the slide 5, and the limiting assembly 3 is arranged on the side wall of the slide 5; the limiting assembly 3 includes a pressure rod 24 and an elastic member 25, the elastic member 25 is arranged on the side wall of the slide 5, the pressure rod 24 is arranged on the elastic member 25, the bracket 4 is provided with an electric telescopic rod 23, the movable end of the electric telescopic rod 23 slides through the bracket 4 and is connected to the slide 5, by driving the slide 5 to move downward, the elastic member 25 and the pressure rod 24 on the slide 5 are driven to move downward, and when the pressure rod 24 gradually presses the film, the cutting knife 2 cuts the film.

[0020] The elastic member 25 includes a support plate 7, a slide bar 8, a spring 9 and a connecting rod 10. The support plate 7 is arranged on the side wall of the slide seat 5. Both ends of the slide bar 8 are arranged on the support plate 7. A slider 11 is slidably sleeved on the slide bar 8. The slider 11 is slidably arranged on the side wall of the slide seat 5. The spring 9 is sleeved on the slide bar 8 and arranged between the slider 11 and the support plate 7. Both ends of the connecting rod 10 are rotatably hinged on the pressure rod 24 and the slider 11 respectively. When the slide seat 5 moves downward, the pressure rod 24 can be driven to move downward. When the pressure rod 24 is pressed on the workbench 6, the pressure rod 24 drives the angle between the connecting rod 10 and the slider 11 to become smaller. At the same time, the slider 11 slides on the slide bar 8, and the elasticity is elastically deformed, and the pressure rod 24 is driven by the connecting rod 10 to press the film.
