[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, as shown in Figures 1-7, provides an online fully automatic slitting device for hard cotton, including two boxes 1. A drive roller 5 and a driven roller 6 are arranged between the two boxes 1 and near both sides. Both ends of the drive roller 5 penetrate the box 1 and are rotatably connected to its bearings, which can achieve the effect of positioning both ends of the drive roller 5. Sliding holes 14 are opened through one side wall of the box 1 above the drive roller 5. Both ends of the driven roller 6 penetrate the sliding holes 14 and are slidably connected to them, which can achieve the effect of positioning both ends of the driven roller 6. The lifting effect inside hole 14 is achieved by lifting blocks 7, which are rotatably connected to the surface of the driven roller 6 near both ends and mounted on bearings. Electric push rods 8 are fixedly connected to the inner wall of one side of the housing 1 above the sliding hole 14. The output ends of the electric push rods 8 are fixedly connected to the top of the lifting blocks 7, allowing the electric push rods 8 to push the lifting blocks 7 up and down. The lifting of the lifting blocks 7, in turn, drives the driven roller 6 up and down. A hexagonal rod 16 is provided between the housings 1, with both ends of the hexagonal rod 16 penetrating the housing 1 and rotatably connected to its bearings. A first bearing sleeve 22 is slidably fitted onto the surface of the hexagonal rod 16 at equal intervals. A second bearing sleeve 24 is slidably fitted onto the surface of the hexagonal rod 16 on one side of the first bearing sleeve 22. The first bearing sleeve 22 and the second bearing sleeve 24 are fixedly connected. An L-shaped plate 23 is rotatably fitted onto the surface of the first bearing sleeve 22. A belt cover 25 is rotatably fitted onto the surface of the second bearing sleeve 24. A turntable 26 is rotatably fitted onto the surface of the second bearing sleeve 24 and fixedly connected inside the belt cover 25. The belt cover 25 is further... A rotating component 27 is rotatably connected to a bearing at one end. A third transmission belt 28 is connected between the turntable 26 and the rotating component 27. A cutting disc 29 is installed at one end of the rotating component 27. This allows the hexagonal rod 16 to rotate, which in turn drives the first bearing sleeve 22 and the second bearing sleeve 24 to rotate. The rotation of the second bearing sleeve 24 drives the turntable 26 to rotate. The rotation of the turntable 26 drives the third transmission belt 28 to rotate. The third transmission belt 28 drives the rotating component 27 to rotate. The rotation of the rotating component 27 drives the cutting disc 29 to rotate.

[0029] Example 2, as shown in Figures 1-7, involves two fixed plates 3 and three connecting plates 4 fixedly connected between two housings 1. Support legs 2 are fixedly connected to one side wall of each housing 1 near the bottom corners, providing support for the bottom of the housing 1. Ring plates 9 are fixedly connected to the inner wall of one side of each housing 1, located on both sides of the lifting block 7. Limiting blocks 10 are embedded and slidably connected inside the ring plates 9, and are fixedly connected to the lifting block 7, limiting its movement. A first pulley 11 is fixedly connected to one end of each drive roller 5. A second pulley 12 is rotatably connected to the inner wall of one side of each housing 1 near the bottom bearing. A third pulley 13 is located below the second pulley 12 and near the center. 11. A first transmission belt 15 is connected between the second pulley 12 and the third pulley 13, which enables the third pulley 13 to rotate and drive the first transmission belt 15. The first transmission belt 15 can drive the drive roller 5 to rotate through the second pulley 12 and the first pulley 11. A fourth pulley 17 is fixedly connected to one end of a hexagonal rod 16. A fifth pulley 18 is rotatably connected to the inner wall of the housing 1 and above the third pulley 13 via a bearing. A second transmission belt 19 is connected between the fourth pulley 17 and the fifth pulley 18, which enables the fifth pulley 18 to drive the second transmission belt 19. The second transmission belt 19 drives the fourth pulley 17 to rotate, and the rotation of the fourth pulley 17 drives the sixth pulley 16 to rotate. The effect of rotating the side rod 16; a motor base 20 is fixedly connected to the inner wall of one side wall of the housing 1 and below the third pulley 13 and the fifth pulley 18. A drive motor 21 is fixedly connected to the top of the motor base 20. The output end of the drive motor 21 is fixedly connected to the third pulley 13 and the fifth pulley 18, which can enable the drive motor 21 to drive the third pulley 13 and the fifth pulley 18 to rotate; a controller 30 is slidably installed at equal intervals on the top of the connecting plate 4. The controller 30 is electrically connected to the hydraulic rod 31, which can enable the controller 30 to control the hydraulic rod 31; hydraulic rods 31 are fixedly connected to the surface of the L-shaped plate 23. The output end of the hydraulic rod 31 is pin-connected to the connecting piece 34. An arc plate 32 is fixedly connected to the surface arc edge of L-shaped plate 23. A connecting rod 33 slides inside the arc plate 32. One end of the connecting rod 33 is rotatably connected to the bearing of belt cover 25, and the other end of the connecting piece 34 is connected to the pin of the connecting rod 33. This allows the hydraulic rod 31 to push the connecting piece 34 down, which in turn causes the connecting rod 33 to down, and the down movement of the connecting rod 33 causes one end of the belt cover 25 to down. Because the arc plate 32 is concentric with the hexagonal rod 16, the connecting rod 33 can slide inside the arc plate 32. A sliding rod 35 passes through and slides above the hexagonal rod 16 on the surface of L-shaped plate 23. Both ends of the sliding rod 35 pass through the housing 1 and are rotatably connected to its bearing, which limits the movement of L-shaped plate 23.

[0030] Working principle: The plastic strip to be cut is passed between the drive roller 5 and the driven roller 6. Then, the electric push rod 8 pushes the lifting block 7 to descend. The lifting block 7 moves up and down, which drives the driven roller 6 to descend, causing the driven roller 6 to squeeze the plastic strip. One of the drive motors 21 drives the third pulley 13 to rotate. The rotation of the third pulley 13 drives the first transmission belt 15. The first transmission belt 15 drives the drive roller 5 to rotate through the second pulley 12 and the first pulley 11. At this time, the controller 30 controls the hydraulic rod 31 to push the connecting piece 34 to descend. The descent of the connecting piece 34 drives the connecting rod 33 to descend. The descent of the connecting rod 33 drives the belt cover. When one end of 25 descends, the cutting disc 29 is pressed against the surface of the plastic belt. Then, the drive motor 21 drives the fifth pulley 18 to rotate. The rotation of the fifth pulley 18 drives the second transmission belt 19, which in turn drives the fourth pulley 17. The rotation of the fourth pulley 17 drives the hexagonal rod 16, which in turn drives the first bearing sleeve 22 and the second bearing sleeve 24. The rotation of the second bearing sleeve 24 drives the turntable 26, which in turn drives the third transmission belt 28. The third transmission belt 28 drives the rotating component 27, which in turn drives the cutting disc 29 to rotate.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the electric push rod 8, drive motor 21, controller 30, and hydraulic rod 31 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
