[0022] Please see Figure 1-4 As shown, the system includes a base plate 14, a support leg 5 fixedly connected to the lower surface of the base plate 14, a rotating shaft 6 rotatably connected to the lower surface of the support leg 5, a connecting frame 7 fixedly connected to the side surface of the rotating shaft 6, a rotating wheel 8 rotatably connected to the inner surface of the connecting frame 7, two placement frames 13 fixedly connected to the upper surface of the base plate 14, each of the two placement frames 13 being provided with a sliding groove 10, a slider 11 slidably connected to the inner surface of each of the two sliding grooves 10, a take-up roller 9 rotatably connected between the two sliders 11, and a motor 12 fixedly connected to the side surface of the slider 11, the take-up roller 9 being driven by the motor 12.

[0023] Specifically: In the initial state, cotton towel material is wound on one of the take-up rollers 9. A motor 12 drives the take-up roller 9 to rotate, and the cotton towel is gradually unwound. The unwound cotton towel passes between the two pad rollers 16 and the lower pressure roller 21, and finally wraps around the other take-up roller 9. The other take-up roller 9 starts to rotate under the drive of another motor 12. As the take-up roller 9 rotates, the unwound cotton towel is gradually wrapped around the take-up roller 9.

[0024] A through hole 25 is provided on the base plate 14. Two slide rails 17 are fixedly connected to the inner wall of the through hole 25. Slider 20 is slidably connected to the inner surface of each slide rail 17. A lower pressure roller 21 is rotatably connected between the two sliders 20. Springs 18 are fixedly connected to the upper surface of each slider 20. Dampers 19 are fixedly connected to the upper surface of each slider 20. A connecting plate 4 is fixedly connected to the upper end of the springs 18 and the dampers 19. A support plate is fixedly connected to the upper surface of each slide rail 17. An electric push rod 3 is fixedly connected to the lower surface of the support plate. The lower end of the electric push rod 3 is fixedly connected to the upper surface of the connecting plate 4. Two brackets 15 are fixedly connected to the upper surface of the base plate 14. A pad roller 16 is rotatably connected to the inner surface of each bracket 15. The slide rail 17 is located between the two brackets 15.

[0025] Specifically: Two pad rollers 16 are distributed on both sides of the lower pressure roller 21 to provide support when the lower pressure roller 21 presses down on the cotton soft towel, ensuring stable transmission of the cotton soft towel. The electric push rod 3 is started, pushing the connecting plate 4 to move downward. The connecting plate 4 presses down on the spring 18 and the damper 19, causing the slider 20 to drive the lower pressure roller 21 to descend. The lower pressure roller 21 presses down on the cotton soft towel, increasing its tension and keeping the cotton soft towel flat during the winding process, preventing wrinkles or loosening.

[0026] A cutting assembly is provided on the base plate 14. The through hole 25, the slide rail 17, and the cutting assembly are located between two placement racks 13. The cutting assembly includes: a support frame 2 and a cutting plate 23. The support frame 2 is fixedly connected to the upper surface of the base plate 14, and the cutting plate 23 is fixedly connected to the inner surface of the support frame 2. The cutting assembly also includes: an electric push rod 1 and a blade 22. The electric push rod 1 is fixedly connected to the inner surface of the support frame 2, and the blade 22 is fixedly connected to the lower end of the electric push rod 1. The cutting assembly also includes: a lower cutting slit 24. The lower cutting slit 24 is set on the cutting plate 23, and the blade 22 is movably connected to the lower cutting slit 24.

[0027] Specifically: When the cotton towel is rolled to a predetermined length or a roll is completed, a cutting operation is required. The electric push rod 21 pushes the blade 22 downward. The blade 22 passes through the lower cut slit 24 on the cutting plate 23 and cuts the cotton towel located on the cutting plate 23, thus completing one rolling and cutting cycle.

[0028] In use, initially, cotton tissue material is wound on one take-up roller 9. A motor 12 drives the take-up roller 9 to rotate, gradually unwinding the cotton tissue. The unwound cotton tissue passes between the two pad rollers 16 and the lower pressure roller 21, eventually winding onto the other take-up roller 9. The other take-up roller 9, driven by another motor 12, begins to rotate. As it rotates, the unwound cotton tissue gradually winds onto it. The two pad rollers 16 are distributed on both sides of the lower pressure roller 21, providing support when the lower pressure roller 21 presses down on the cotton tissue, ensuring stable transport of the cotton tissue. An electric push rod... 3. Start the circuit and push the connecting plate 4 downward. The connecting plate 4 presses down the spring 18 and the damper 19, causing the slider 20 to drive the lower pressure roller 21 to descend. The lower pressure roller 21 presses down on the cotton towel, increasing its tension and keeping the cotton towel flat during the winding process to prevent wrinkles or loosening. When the cotton towel is wound to a predetermined length or a roll is completed, a cutting operation is required. The electric push rod 21 pushes the blade 22 downward. The blade 22 passes through the lower cut slit 24 on the cutting plate 23 and cuts the cotton towel located on the cutting plate 23, thus completing one winding and cutting cycle.
