The four fixing frames 14 are all arranged on the outside of the extrusion roller 11. The inner side of the fixing frames 14 is fixedly connected with the second electric push rod 15. When not in use, the groove plate 16 is driven to be retracted by the second electric push rod 15 without affecting the operation of the extrusion roller 11. The output end of the second electric push rod 15 is fixedly connected with the groove plate 16, and the brush plate 18 is slidably connected in the groove plate 16. The top of the support plate 7 is fixedly connected with a material box 19, and an electric heating plate 20 is arranged inside the material box 19.

[0033] Reference Figure 2 The adjustment component includes a linear guide rail 2, and the four linear guide rails 2 are fixedly connected to the base 1. The four linear guide rails 2 are slidably connected to the outside with a moving seat 3. The movement of the moving seat 3 can drive the upper limiting roller 6 to move. The top of the moving seat 3 is fixedly connected with a first electric push rod 4, and the limiting roller 6 can be driven to rise and fall through the first electric push rod 4.

The first gear 10 and the second gear 13 are both arranged on the outside of the support plate 7. The first gear 10 is meshed and connected with the second gear 13 to play a transmission role. The second gear 13 can be driven to move in opposite directions through the first gear 10.

[0035] Working principle: When using this device, firstly, the liquid raw material is passed through the discharge barrel 21 into the discharge box 19. After entering the discharge box 19, the electric heating plate 20 is started to generate heat, so as to achieve the effect of heat preservation and heating inside the discharge box 19, so as to keep the temperature of the liquid material flowing. The raw material is discharged from the discharge barrel 22 by controlling the valve. When the liquid raw material falls between the extrusion rollers 11, the motor 8 is started to drive the first rotating shaft 9 to rotate, and the second gear 13 and the second rotating shaft 12 are driven to rotate through the meshing connection, so as to realize the opposite rotation of the extrusion rollers 11. When extruding inward, the material is moved to both sides through the guide plate 24, and the extrusion of the film is completed through the extrusion roller 11. The extruded film moves upward from the bottom of the limiting roller 6. , the film provides a lifting force for the limiting roller 6. When the film becomes loose, the linear guide 2 drives the moving seat 3 to move, and at the same time cooperates with the first electric push rod 4 to drive the connecting block 5 and the limiting roller 6 to rise and fall, so as to adjust the position and height of the limiting roller 6, and ensure that the film is always transmitted in a tight state to avoid damage caused by too loose. When the film is not processed, the motor 8 is started to drive the extrusion roller 11 to rotate, and the second electric push rod 15 drives the groove plate 16 and the brush plate 18 to approach the extrusion roller 11. When the brush plate 18 contacts the rotating extrusion roller 11, the debris on the surface of the extrusion roller 11 can be cleaned, and the brush plate 18 can be extended and retracted in the groove plate 16 through the spring 17, so that the brush plate 18 has stronger adaptability and better cleaning effect.
