A platform 4 is fixedly connected to a position near the center of the surface of the bottom plate 1. A support frame 5 is fixedly connected to the top surface of the platform 4. A hydraulic rod 6 is fixedly connected to the inside of the support frame 5. The bottom end of the hydraulic rod 6 is fixedly connected to a mounting frame 7. A cutting die 8 is snap-fitted inside the mounting frame 7. A bolt 9 is threadedly installed on one side of the mounting frame 7. A support plate 13 is fixedly connected to the surface of the bottom plate 1. A pressure roller 14 is rotatably connected to the inside of the support plate 13. A motor 15 is fixedly connected to the outer wall of the support plate 13;

[0023] Further, a baffle 10 is slidably sleeved on the surface of the bolt 9. A pressing block 11 is fixedly connected to one side of the baffle 10. The baffle 10 is fixedly connected to one side of the cutting die 8 through the bolt 9;

[0024] During operation, due to the structural design that the baffle 10 is fixedly connected to one side of the cutting die 8 through the bolt 9, the stability of the cutting die 8 during installation is improved by installing the baffle 10.

[0025] Further, a conveyor 12 is fixedly connected to the surface of the bottom plate 1. The conveyor 12 is attached to the front side of the platform 4;

[0026] During operation, due to the structural design that the conveyor 12 is attached to the front side of the platform 4, it is convenient for the conveyor 12 to transport raw materials in a timely manner.

[0027] Further, two support plates 13 are taken as a group. A group of support plates 13 are fixedly connected to both the front and rear sides of the bottom plate 1 above the platform 4;

[0028] During operation, due to the structural design that a group of support plates 13 are fixedly connected to both the front and rear sides of the bottom plate 1 above the platform 4, the stability of the movement of the protective film raw material 3 is improved.

[0029] Further, two pressure rollers 14 are connected to the inside of a single support plate 13. One ends of the two pressure rollers 14 both pass through the inside of the support plate 13 and are fixedly connected to gears 16. The two gears 16 are meshed with each other;

[0030] During operation, due to the structural design of the meshing connection between the two gears 16, when the motor 15 drives one pressure roller 14 to rotate, the two pressure rollers 14 rotate simultaneously and in opposite directions.

[0031] Furthermore, the pressing block 11 is arranged directly above the conveyor 12, and the bottom end of the pressing block 11 is lower than the bottom surface of the pressing knife die 8.

[0032] During operation, due to the structural design that the pressing block 11 is arranged directly above the conveyor 12 and the bottom end of the pressing block 11 is lower than the bottom surface of the pressing knife die 8, it is convenient for the pressing block 11 to extrude the processed and cut protective film, so that the finished protective film falls off the surface of the conveyor 12.

[0033] Working principle: First, the protective film raw material 3 is fixedly installed inside the turntable 2, and one end of the protective film raw material 3 passes through the inside of the support plate 13 and the surface of the platform 4. The hydraulic rod 6 is started by an external power supply. The hydraulic rod 6 drives the mounting frame 7 to lower the pressing knife die 8 to perform die cutting on the protective film raw material 3. At the same time, the motor 15 is started by an external power supply. The motor 15 drives the protective film raw material 3 to move continuously through the connection method of meshing of the pressure roller 14 and the two gears 16. When the pressing knife die 8 descends, the pressing block 11 outside the baffle 10 descends synchronously to extrude the raw material after die cutting. The finished protective film is separated from the protective film raw material 3 and falls onto the surface of the conveyor 12. By removing the bolts 9 to disassemble the mounting frame 7 and the baffle 10, and then sliding to disassemble the pressing knife die 8, it is convenient to replace the pressing knife die 8 of different sizes, improving the adaptability of the device.
