[0021] Please see Figure 1-5 This utility model provides a technical solution: a fully automatic blade adjustment system for a film slitting machine, including a first support frame 1. A dust collection box 22 is fixedly connected to the lower surface of the first support frame 1. The first support frame 1 serves to limit the position of the dust collection box 22. Multiple filter screens 4 are installed inside the dust collection box 22 to collect and filter the absorbed dust. A protective net 3 is fixedly connected to one side of the dust collection box 22 to protect the internal components. A fan is fixedly connected to the lower surface of the first support frame 1. 5. The output end of the fan 5 is fixedly connected to one side of the dust collection box 22. The fan 5 works in conjunction with the dust collection box 12 to extract and remove dust from the surface of the membrane body 7. The input end of the fan 5 is fixedly connected to a rubber hose 6. The first support frame 1 has two first sliding grooves 11 inside, and the dust collection box 12 is slidably connected inside each of the two first sliding grooves 11. The dust collection box 12 consists of two parts. The middle of the dust collection box 12 has a slot to facilitate the passage of the membrane body 7, and both sides of the dust collection box 12 are hollow. The upper part of the dust collection box 12... A dustproof net 14 is fixedly connected to the surface of the dust collection box 12 to prevent dust from entering the device. Two pressure sensors 13 are fixedly connected to the upper surface of the dust collection box 12, and compression springs 15 are fixedly connected to the upper surface of each pressure sensor 13. When the film body 7 pulls the dust collection box 12 upward, it compresses the compression springs 15, keeping the pressure sensors 13 at a certain pressure value, ensuring that the film body 7 is always in a taut state. When the film is fed too fast and not cut completely, the compression springs 15 extend, and the pressure value of the pressure sensors 13 decreases. The controller in the control box 21 controls the first conveying device 2 to slow down the conveying speed and the second conveying device 23 to speed up the conveying speed, so that the film body 7 drives the dust collection box 12 to move upward, compressing the compression spring 15, so that the pressure sensor 13 always maintains a certain value, keeping the film body 7 taut and flat. The tops of the two compression springs 15 are respectively fixedly connected to the inner top wall of the first slide groove 11. One end of the dust collection box 12 is fixedly connected to the end of the rubber hose 6 away from the fan 5. The rubber hose 6 is used to connect the dust collection box 12 to the fan 5.

[0022] Two support blocks 8 are fixedly connected to one side of the first support frame 1. Limiting posts 20 are set inside the two support blocks 8, which serve to limit the limiting wheel 9.

[0023] The outer surface of the limiting post 20 is provided with a limiting wheel 9, and both ends of the limiting wheel 9 are provided with a limiting spring 10. The limiting wheel 9 serves to place the film body 7.

[0024] The outer surface of the limiting wheel 9 is provided with a thin film body 7. The surface of the thin film body 7 is in contact with the inside of the dust collection box 12. The dust collection box 12 is used to absorb the dust on the surface of the thin film body 7.

[0025] The first support frame 1 is provided with a first conveying device 2 on one side and a second conveying device 23 on the other side. The first conveying device 2 and the second conveying device 23 are used to convey the film body 7. The first conveying device 2 and the second conveying device 23 are both driven by a motor to rotate rollers. The rollers rotate through a gear on one roller and a gear on the other roller, so that the two rollers squeeze the film body 7 and convey the film body 7.

[0026] The first support frame 1 has a second sliding groove 17 inside, and a cutter 19 is slidably connected inside the second sliding groove 17. The cutter 19 is used to cut the film body 7.

[0027] The lower surface of the first support frame 1 is fixedly connected to a control box 21, and the upper surface of the first support frame 1 is fixedly connected to a second support frame 16. The control box 21 is used to control the movement of the electric telescopic rod 18, the first conveying device 2, and the second conveying device 23.

[0028] Among them, the lower surface of the second support frame 16 is fixedly connected to an electric telescopic rod 18, and the output end of the electric telescopic rod 18 is fixedly connected to the upper surface of the cutter 19. The electric telescopic rod 18 is used to drive the cutter 19 to move.

[0029] Among them, the motor and electric telescopic pole are existing technologies and will not be described in detail here. Matching the motor and electric telescopic pole are connecting wires, power supply, microcontroller, etc., which are existing structures and will not be described in detail here.

[0030] Working principle: In use, the limiting wheel 9 is inserted into the surface of the limiting post 20, and limiting springs 10 are placed at both ends of the limiting wheel 9. The two limiting springs 10 push the limiting wheel 9 to the middle position of the limiting post 20, and apply a certain squeezing force to the limiting wheel 9 to prevent it from rotating randomly. Then, the film is sequentially passed through the inside of the first conveying device 2, the middle position of the dust collection box 12, and the middle position of the second conveying device 23. The controller in the control box 21 drives the second conveying device 23 and the first conveying device 2 to move, so that the second conveying device... The second conveyor 23, when pressed against the first conveyor 2, causes the film body 7 to move. This tauts the film body 7 between the second conveyor 23 and the first conveyor 2, causing the dust collection box 12 to move upwards. The compression spring 15 compresses the pressure sensor 13, stabilizing it at the specified value. When the first conveyor 2 moves too fast, the dust collection box 12 moves downwards, the compression spring 15 resets, and the pressure sensor 13 detects a smaller value. At this point, the controller in the control box 21 slows down the conveying speed of the first conveyor 2 and increases the conveying speed of the second conveyor 23, causing the film body 7 to move. Once the membrane body 7 becomes taut and flat again to prevent it from stacking, the blower 5 is activated, allowing outside air to enter the dust collection box 12 through the dust filter 14. The dust filter 14 filters the air entering the dust collection box 12 and makes the air contact the upper and lower surfaces of the membrane body 7, blowing away the dust on the surface of the membrane body 7 and moving it to the other end to clean the surface of the membrane body 7. The dust-laden air enters the dust collection box 22 through the rubber hose 6 and the blower 5, and is filtered through the filter 4. The filtered dust remains inside the dust collection box 22. The air is discharged through the protective net 3 to clean the dust on the surface of the film body 7, preventing dust from adhering to the surface of the film body 7 and affecting subsequent processing. Then, the dust-removed film body 7 is conveyed into the right side of the device by the second conveying device 23. When the controller in the control box 21 uses the second conveying device 23 to convey the film body 7 to a certain distance, the electric telescopic rod 18 is activated. The electric telescopic rod 18 drives the cutter 19 to slide inside the second slide groove 17, so that the cutter 19 contacts the step on the upper surface of the first support frame 1 to realize the cutting operation of the film.
