[0026] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a film pressing device for a laminating machine of the utility model in conjunction with the accompanying drawings.

[0027] like Figure 1-4As shown, a film pressing device for a laminating machine of the utility model comprises a support frame 1, on which a support plate 2 is installed, the support frame 1 comprises two parallel vertical plates 12 and a horizontal plate 14 located between the top ends of the two vertical plates 12, the top side walls of the vertical plates 12 are provided with a card slot 15 that matches the width of the horizontal plate 14, the two ends of the horizontal plate 14 are fixedly connected to the vertical plates 12 by bolts, and the bottom of the vertical plates 12 is provided with a fixing seat 13, by setting the support frame 1 to be composed of the vertical plates 12 and the horizontal plate 14, it is convenient to disassemble and install the support frame 1, so as to facilitate its handling and transportation, when in use, the two vertical plates 12 are installed on both sides of the laminating machine through the fixing seat 13, and when laminating, the film and the product are moved forward under the pressure roller 10 under the action of the laminating machine. The support plate 2 is installed on the side wall of the horizontal plate 14, and the two ends of the support plate 2 are fixedly connected to the horizontal plate 14 by bolts.

[0028] A movable plate 19 parallel to the support plate 2 is provided above the support plate 2, and a cylinder 3 is installed in the middle part of the upper surface of the support plate 2. The top end of the piston rod 4 of the cylinder 3 penetrates the movable plate 19 and is fixedly connected with a pull block 5, and a spring 6 is sleeved on the piston rod 4, the top end of the spring 6 is connected to the bottom of the pull block 5, and the bottom of the spring 6 is connected to the upper surface of the movable plate 19. Slide rods 7 are provided at the bottom of both ends of the movable plate 19, and the bottom of the slide rod 7 penetrates the support plate 2 and is provided with a side plate 9. A pressure roller 10 is rotatably connected between the two side plates 9 through a bearing. Mounting holes 16 are provided on the upper surfaces of both ends of the support plate 2, and slide tubes 8 are installed in the mounting holes 16. A fixed plate 17 is provided at the bottom of the slide tube 8, and the fixed plate 17 is fixedly connected to the support plate 2 by bolts, and the slide rod 7 is slidably connected to the slide tube 8 up and down. The setting of the slide tube 8 plays a limiting role on the slide rod 7.

[0029] A guide plate 11 is arranged between the front side walls of the two side plates 9. The guide plate 11 is composed of a horizontal plate and an arc plate, and the bottom of the horizontal plate is flush with the bottom of the pressure roller 10. Through the cooperation between the arc plate and the horizontal plate on the guide plate 11, the film can be guided first to achieve a step-by-step effect, thereby avoiding the phenomenon that the film directly contacts the pressure roller 10 and affects it.

[0030] A sliding hole 18 is provided in the middle part of the surface of the movable plate 19, and the piston rod 4 is connected to the sliding hole 18 by sliding up and down. Through the setting of the sliding hole 18, the piston rod 4 can slide up and down with the movable plate 19. When film pressing is required, the cylinder 3 is started to make the piston rod 4 pull the pulling block 5. At this time, the pulling block 5 will move downward to squeeze the spring 6, and the spring 6 will push the two sliding rods 7 to move downward, so that the pressing roller 10 can press the film. When the compression amount of the spring 6 is reached, the sliding rod 7 stops moving downward, so that the products pressed each time are at the same height, and the pressing force is stable and uniform. In this way, the force of the cylinder 3 can be effectively avoided from acting directly on the movable plate 19. Since the compression amount of the spring 6 is constant, the force is always uniform, thereby ensuring product quality. The pressing force can be adjusted by adjusting the compression amount of the spring 6, and it is highly flexible.
