DETAILED DESCRIPTION

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] Example: A mechanism for adjusting the unfolding of printed film; please refer to [link / reference]. Figures 1-4 This utility model provides a technical solution: a winding and unwinding adjustment mechanism for printed film, including a frame 1, on which a magnetic powder brake 2 is fixedly installed. The magnetic powder brake 2 can provide a constant resistance torque to ensure that the printed film maintains stable tension during the unwinding process. The output end of the magnetic powder brake 2 is fixedly connected to an unwinding roller 3, which is rotatably connected to the frame 1. A winding motor 11 is fixedly installed on the frame 1. The rotational speed of the winding motor 11 directly affects the winding speed of the printed film, and thus affects the tension. The output end of the winding motor 11 is fixedly connected to a winding roller 12, which is rotatably connected to the frame 1.

[0025] A support frame 4 is fixedly connected to the frame 1. A connecting shaft 5 is fixedly connected to the support frame 4. A guide roller 6 is rotatably connected to the connecting shaft 5. Five guide rollers 6 are provided. A push rod motor 7 is fixedly installed on the support frame 4. A slider 8 is fixedly connected to the push rod end of the push rod motor 7. The slider 8 is slidably connected to the support frame 4. A fixed shaft 9 is fixedly connected to one side of the slider 8. A tension roller 10 is rotatably connected to the fixed shaft 9. When the tension of the printing film changes, the tension roller 10 will automatically adjust its position under the action of the push rod motor 7 to keep the printing film in an appropriate tension state.

[0026] A motor 13 is fixedly installed on the support frame 4. A drive gear 14 is fixedly connected to the output end of the motor 13. Two driven gears 15 are meshed on the drive gear 14. A brush roller 16 is fixedly connected to the driven gear 15. The two brush rollers 16 rotate in the same direction and brush the impurities on the printing film to one side. A vacuum cleaner 17 is fixedly connected to the support frame 4 on this side to suck away the impurities.

[0027] In use, the unwinding roller 3 begins to unwind the printing film under the resistance of the magnetic powder brake 2. The printing film is released from the unwinding roller 3, passes under the first guide roller 6, passes over the tension roller 10, and the push rod motor 7 controls the slider 8 to move up and down, thereby driving the tension roller 10 to move up and down and adjusting the tension of the printing film. The printing film then passes under the second guide roller 6, passes over the third guide roller 6, passes horizontally over the fourth guide roller 6, passes under the fifth guide roller 6, and then over the take-up roller 12. The take-up motor 11 drives the take-up roller 12 to take up the printing film. When passing the third and fourth guide rollers 6, the motor 13 above drives the brush roller 16 through gears. The two brush rollers 16 rotate in the same direction, brushing the impurities on the printing film towards the vacuum cleaner 17, which then sucks up the impurities.

[0028] The principle of this invention is as follows: In use, the unwinding roller 3 begins to unwind the printing film under the resistance of the magnetic powder brake 2. The printing film is released from the unwinding roller 3, passes under the first guide roller 6, passes over the tension roller 10, and the push rod motor 7 controls the slider 8 to move up and down, thereby driving the tension roller 10 to move up and down to adjust the tension of the printing film. The printing film then passes under the second guide roller 6, passes over the third guide roller 6, passes horizontally over the fourth guide roller 6, passes under the fifth guide roller 6, and then over the take-up roller 12. The take-up motor 1... 1. The take-up roller 12 drives the printing film to take up the film. When it passes the third and fourth guide rollers 6, the motor 13 above drives the brush roller 16 through gears. The two brush rollers 16 rotate in the same direction, brushing the impurities on the printing film toward the vacuum cleaner 17. The vacuum cleaner 17 picks up the impurities, thus cleaning the surface of the printing film and preventing dust and other impurities from affecting the printing quality. The take-up motor 11, magnetic powder brake 2 and tension roller 10 work together to adjust the tension of the printing film, ensuring that the printing film can maintain appropriate tension and stable transmission under different working conditions, thereby improving the quality and efficiency of printing.
