Technical Field
[0001] This application relates to the field of diaper processing equipment technology, specifically a wood pulp crushing device for diaper processing. Background Technology
[0002] Disposable diapers have become ubiquitous in people's lives. They can be divided into adult diapers and baby diapers depending on the user group. Since diapers come into full contact with the human skin during use, people pay great attention to the quality of diapers and the comfort they bring to the human body. The core technology of diapers is the core, and wood pulp is an important component of the diaper core.
[0003] In the existing technology, wood pulp needs to be crushed and then screened as needed during processing. However, the crushed wood pulp may clog the filter holes on the filter plate during screening, which will lead to low screening efficiency or even failure to screen after a period of use. Therefore, there is a need for a wood pulp crushing device for diaper processing. Utility Model Content

There are two crushing rollers 3 in total, one of which is fixedly installed with a first gear 5 through the side wall of the top box 1. The first gear 5 meshes with a second gear 6. When the first motor 2 is started, one crushing roller 3 is driven to rotate, which in turn drives the first gear 5 to rotate, which in turn drives the second gear 6 meshing with it to rotate, which in turn drives the other crushing roller 3 to rotate, thereby crushing the wood pulp. The bottom box 4 is also provided with a discharge port (not shown in the figure).
[0032] In the technical solution of this application, such as Figure 2 As shown, a first pulley 7 is fixedly installed on the second gear 6, a belt 8 is fitted on the first pulley 7, and a second pulley 9 is fitted on the belt 8. The second pulley 9 is rotatably connected to the outer wall of the base box 4. When the second gear 6 rotates, it will drive the first pulley 7 to rotate, thereby driving the belt 8 to move, which in turn drives the second pulley 9 to rotate.
[0033] In the technical solution of this application, such as Figure 3 and 4 As shown, a reciprocating screw 13 is fixedly installed on the second pulley 9. The other end of the reciprocating screw 13 is rotatably installed on the inner wall of the base box 4. A moving block 23 is threadedly installed on the reciprocating screw 13. A connecting plate 12 is fixedly installed on the inner wall of the base box 4 below the reciprocating screw 13. The moving block 23 abuts against the connecting plate 12. When the second pulley 9 rotates, it will drive the reciprocating screw 13 to rotate, thereby driving the moving block 23 to move. The connecting plate 12 can guide the moving block 23 to prevent the moving block 23 from rotating when the reciprocating screw 13 moves.
[0034] In the technical solution of this application, such as Figure 6 As shown, a rotating shaft 21 is fixedly installed on the movable block 23, and a winding wheel 20 is fixedly installed on the rotating shaft 21. A torsion spring 22 is sleeved on the rotating shaft 21. One end of the torsion spring 22 is fixedly connected to the movable block 23, and the other end of the torsion spring 22 is fixedly connected to the winding wheel 20. A pull rope 19 is wound on the winding wheel 20. When the winding wheel 20 rotates, it drives the torsion spring 22 to rotate. When the external force is removed, the winding wheel 20 will be driven to reset under the action of the torsion spring 22.
[0035] In the technical solution of this application, such as Figure 2 and 3As shown, a fixed frame 14 is fixedly installed on the side wall of the movable block 23. A striking plate 17 is slidably installed inside the fixed frame 14. The lower end of the striking plate 17 is fixedly connected to the pull rope 19. A spring is also provided at the lower end of the striking plate 17, and the other end of the spring is fixedly connected to the inner wall of the fixed frame 14. When the pull rope 19 pulls the striking plate 17 down, after the force of the pull rope 19 is removed, the striking plate 17 will be pushed up by the spring, so that it will strike the filter plate 10 above, so that the blocked wood pulp can fall down.
[0036] In the technical solution of this application, such as Figure 6 As shown, a rotating gear 16 is fixedly installed on the winding wheel 20. When the rotating gear 16 rotates, it will drive the structure on it to rotate.
[0037] In the technical solution of this application, such as Figure 2 As shown, multiple racks 15 are fixedly installed on the connecting plate 12. The racks 15 can mesh with the rotating gear 16, and the rotating gear 16 can be driven to rotate through the cooperation of the racks 15 and the rotating gear 16.
[0038] In the technical solution of this application, such as Figure 2 and 3 As shown, a filter plate 10 is fixedly installed on the side wall of the bottom box 4. A guide block 11 is fixedly installed on the top surface of the filter plate 10. A protective pad 18 is fixedly installed on the bottom surface of the filter plate 10. The guide block 11 can guide the crushed wood pulp to the filter plates 10 on both sides. The protective pad 18 can prevent the striking plate 17 from damaging the filter plate 10 when striking.
[0039] In operation, the first motor 2 is started, which drives one crushing roller 3 to rotate, thereby driving the first gear 5 to rotate, which in turn drives the second gear 6 meshing with it to rotate, thus driving the other crushing roller 3 to rotate, thereby crushing the wood pulp. When the second gear 6 rotates, it drives the first pulley 7 to rotate, which in turn drives the belt 8 to move, which in turn drives the second pulley 9 to rotate. When the second pulley 9 rotates, it drives the reciprocating screw 13 to rotate, which in turn drives the moving block 23 to move. The connecting plate 12 can guide the moving block 23 to prevent the moving block 23 from rotating when the reciprocating screw 13 moves. When in operation, the rotating gear 16 and the rack 15 mesh, which drives the rotating gear 16 to rotate. When the rotating gear 16 rotates, it drives the take-up wheel 20 to rotate. When the take-up wheel 20 rotates, it drives the torsion spring 22 to rotate. When the external force is removed, the torsion spring 22 will drive the take-up wheel 20 to reset. The lower end of the striking plate 17 is also provided with a spring, and the other end of the spring is fixedly connected to the inner wall of the fixed frame 14. When the pull rope 19 pulls the striking plate 17 down, after the force of the pull rope 19 is removed, the spring will push the striking plate 17 up, so that it strikes the filter plate 10 above, allowing the blocked wood pulp to fall down.
