A filter plate 4 is installed inside the collection groove 2. A negative pressure motor 5 is installed on the bottom inner wall of the collection groove 2. The output end of the negative pressure motor 5 is provided with a rotating shaft 6. Three fan blades 7 are installed on the outer wall of the bottom end of the rotating shaft 6. One end of the rotating shaft 6 rotates through the upper side of the filter plate 4 and is fixedly connected with a cleaning brush 8. A connecting cavity 9 is formed inside the cleaning brush 8. A spring 10 is fixedly connected to one side of the connecting cavity 9. A brush 11 is fixedly connected to one side of the spring 10. One side of the collection groove 2 is connected with an exhaust pipe 12. One end of the exhaust pipe 12 is communicated with the outside.

A control panel 35 is installed on one side of the workbench 1. During operation, in practical applications, the debris generated during the slitting process will be centrally collected. More and more debris will accumulate on the filter plate 4, blocking the filter holes, resulting in a weakened suction force of the dust suction hood 3 and reducing the collection efficiency of the debris. The negative pressure motor 5 is started, driving the rotating shaft 6 to rotate, and the fan blades 7 rotate accordingly, so that the debris generated during the slitting of the paper bag is sucked into the dust suction hood 3 under negative pressure and then enters the collection groove 2. After that, the debris is blocked by the filter plate 4 and remains in the collection groove 2, and the filtered air is discharged to the outside through the exhaust pipe 12. While the rotating shaft 6 rotates, the cleaning brush 8 and the brush 11 also rotate. Under the action of the spring 10, the brush 11 can adapt to the space in the collection groove 2. The cleaning brush 8 and the brush 11 comprehensively clean the filter plate 4, preventing the debris from accumulating and blocking the filter holes of the filter plate 4, ensuring the filtering effect of the filter plate 4 and the air circulation, thus realizing the continuous collection of the debris and the automatic cleaning function of the filter plate 4. Finally, the activity door 13 can be opened through the handle 14 to handle the debris.

[0024] Please refer to Figures 1-4As shown, a fixed plate 19 is installed on the top side of the workbench 1. A driving motor 20 is installed on one side of the fixed plate 19. The output end of the driving motor 20 is installed with a rotating shaft 21. A number of positioning holes 22 are equidistantly installed inside the rotating shaft 21. Three mounting rings 23 are slidably installed on the outer wall of the rotating shaft 21. A cutting knife 24 is assembled on one side of the mounting ring 23. Limiting holes 25 are respectively opened inside the mounting rings 23. A locking screw 26 is rotatably installed through the positioning holes 22 inside the limiting holes 25. During operation, in the process of paper bag production, it is necessary to cut a large sheet of base paper into paper sizes suitable for making shopping bags of specific sizes through slitting operation. When it is necessary to adjust the distance between the cutting knives 24, first loosen the locking screw 26 to make the mounting ring 23 slide on the outer wall of the rotating shaft 21. According to the size requirements of the paper bags to be produced, slide the mounting ring 23 to a suitable position and tighten the locking screw 26. Then start the driving motor 20, and the rotating shaft 21 at its output end rotates, driving the cutting knives 24 to rotate accordingly, and slit the passing paper, so as to meet the slitting requirements of paper bags of different sizes.

[0025] Please refer to Figures 1-5 As shown, support plates 15 are installed at both ends of the top side of the workbench 1. A paper unwinding roller 16 and a paper winding roller 17 are respectively installed inside the support plates 15. A winding motor 18 is installed on one side of the support plates 15. Two vertical plates 27 are symmetrically installed at one end of the top side of the workbench 1. Through grooves 28 are respectively opened inside the vertical plates 27. A support rod 29 is fixedly connected between both sides of the through groove 28. A limiting ring 30 is slidably installed on the outer wall of the support rod 29. A fastening screw 31 is rotatably installed inside one of the limiting rings 30. An installation frame 32 is fixedly connected between the two limiting rings 30. A tension roller 33 is rotatably installed between the installation frames 32. A handle 34 is installed on the top side of the installation frame 32. During operation, when the tension of the paper is unstable during the conveying process, the paper will become loose or taut. Loosen the fastening screw 31 to release the fixation of the limiting ring 30, and then pull the handle 34, which can drive the installation frame 32 to move, and the limiting ring 30 slides along the support rod 29, so as to adjust the position of the tension roller 33. Then tighten the fastening screw 31 to prevent the paper from wrinkling during the slitting process. The paper unwinding roller 16 is wound with the paper to be slit. The paper is output from the paper unwinding roller 16, the stretched paper passes through the top side of the tension roller 33, and then passes through the bottom side of the cutting knife 24 for slitting. Then the winding motor 18 is started to drive the paper winding roller 17 to rotate. Under the rotation of the paper winding roller 17, the slit paper is wound up, realizing the automatic winding of the paper and improving the degree of production automation.

[0026] Working principle: When it is necessary to adjust the spacing of the cutting knives 24, first loosen the locking screw 26 to make the mounting ring 23 slide on the outer wall of the rotating shaft 21. According to the size requirements of the paper bags to be produced, slide the mounting ring 23 to the appropriate position and tighten the locking screw 26, so as to meet the slitting requirements for paper bags of different sizes;

[0027] Release the fixation of the limit ring 30 by loosening the fastening screw 31. Then, pull the handle 34, which can drive the mounting bracket 32 to move. The limit ring 30 slides along the support rod 29, thereby adjusting the position of the tension roller 33. Then, the fastening screw 31 can be tightened to prevent the paper from wrinkling during the slitting process;

[0028] The unwind roller 16 is wound with the paper to be slit. The paper is output from the unwind roller 16. The stretched paper passes through the top side of the tension roller 33 and then passes through the bottom side of the cutting knives 24. Start the drive motor 20, and the rotating shaft 21 at its output end rotates, driving the cutting knives 24 to rotate accordingly to slit the passing paper. Then, the winding motor 18 is started to drive the winding roller 17 to rotate. Under the rotation of the winding roller 17, the slit paper is wound, realizing the automatic winding of the paper and improving the degree of production automation;

[0029] The negative pressure motor 5 is started to drive the rotating shaft 6 to rotate, and the fan blades 7 rotate accordingly, so that the debris generated during the slitting of the paper bags is sucked into the dust suction hood 3 under the negative pressure and then enters the collection tank 2. After that, the debris is blocked by the filter plate 4 and remains in the collection tank 2, and the filtered air is discharged to the outside through the exhaust pipe 12. While the rotating shaft 6 is rotating, the cleaning brush 8 and the brush 11 also rotate accordingly. Under the action of the spring 10, the brush 11 can adapt to the space in the collection tank 2. The cleaning brush 8 and the brush 11 comprehensively clean the filter plate 4 to prevent the debris from accumulating and blocking the filter holes of the filter plate 4, ensuring the filtering effect of the filter plate 4 and the air circulation. Thus, the continuous collection of debris and the automatic cleaning function of the filter plate 4 are realized. Finally, the movable door 13 can be opened through the handle 14 to handle the debris.
