Description

Technical Field

[0001] The present invention relates to the technical field of waste paper recycling, and in particular to a pulping device for recycling and reusing waste paper to produce paper products. Background Art

[0002] With growing global environmental awareness and the increasing demand for sustainable resource utilization, waste paper recycling and reuse to produce paper products has become a key development direction for the papermaking industry. Pulping is a key step in the waste paper recycling process, breaking up the waste paper and dispersing it into a fiber suspension, providing qualified raw materials for subsequent papermaking processes. Pulping equipment for waste paper recycling and reuse to produce paper products is a specialized equipment designed to achieve this goal.

[0003] However, most existing pulping devices used to recycle waste paper into paper products employ a relatively simple shredding method, typically shredding the waste paper in only one direction. This results in inadequate shredding, making it difficult to fully disperse some waste paper fibers, and thus impacting the quality of the subsequent pulp. Furthermore, existing devices often employ a fixed agitation method, with the agitator shaft and stirring rod moving in a single pattern. This makes it difficult to fully mix the water and shredded waste paper, resulting in suboptimal pulping and prone to uneven fiber concentrations, which in turn impacts the quality of paper products. Summary of the Invention

[0027] The box body 1 is provided with a stirring mechanism connected to the reciprocating mechanism, and the stirring mechanism includes two round rods 16 that are arranged on the fixed plate 17. One end of the two round rods 16 is fixedly connected to the bottom of the first movable plate 14. The other end of the two round rods 16 is fixedly installed with the same second movable plate 19 located below the first bevel gear 18. The second movable plate 19 is provided with a stirring shaft 21 that is rotatably connected to it. The stirring shaft 21 can rotate on the second movable plate 19 and stir the pulp in the box body 1 at the same time through the stirring rod 22. The top of the stirring shaft 21 is provided with a groove 23. The bottom of the reciprocating screw rod 15 is fixedly provided with a rotating block 20. The block 20 rotates driven by the reciprocating screw 15, and at the same time cooperates with the groove 23 at the top of the stirring shaft 21 to drive the stirring shaft 21 to rotate. A plurality of stirring rods 22 located below the mounting tube 9 are fixedly mounted on the outer wall of the stirring shaft 21, and an auxiliary gear 33 located in the box body 1 is fixedly mounted on the outer wall of the mounting tube 9. A rack 36 meshing with the auxiliary gear 33 is fixedly mounted on the bottom of the second movable plate 19. The cross-section of the rotating block 20 is square and the groove 23 is adapted, so that the rotating block 20 can fit closely with the groove 23, and drive the stirring shaft 21 to rotate synchronously when the reciprocating screw 15 rotates, without affecting the up and down movement of the second movable plate 19.

[0028] When the present invention is used, waste paper is put into the housing 13 through the input port 12, and then the first motor 2 and the second motor 11 are started and water is transported into the box body 1 through the water pipe 7. After the second motor 11 is started, the second rotating shaft 30 and the spiral blade 29 rotate. The rotation of the spiral blade 29 enables the waste paper to be continuously transported into the box body 1. After the first motor 2 is started, the reciprocating screw 15, the first bevel gear 18 and the rotating block 20 rotate accordingly. When the reciprocating screw 15 rotates, the first movable plate 14 will reciprocate up and down, and the first movable plate 14 will reciprocate up and down through the first movable plate 14. The movable plate 14 drives the moving block 3, the pressure rod 4 and the pressure plug 31 to move accordingly, thereby causing the pressure plug 31 to slide up and down in the pressure cylinder 5. By providing a connecting pipe 6, the incompressible liquid in the pressure cylinder 5 and the fixed box 25 can be circulated, thereby enabling the piston 34 to slide back and forth in the fixed box 25. By providing a linkage rod 35, the mounting rod 32 and the crushing saw teeth 28 can be reciprocated. Since the two sets of crushing saw teeth 28 are arranged perpendicular to each other, the waste paper conveyed into the box body 1 can be crushed in different directions.

[0029] When the first bevel gear 18 rotates, the first bevel gear 18 and the second bevel gear 24 are meshed with each other, thereby enabling the first rotating shaft 26 to rotate, and then enabling the crushing knife 27 to rotate, so that the waste paper conveyed into the box body 1 can be rotationally crushed. When the first movable plate 14 moves back and forth, the round rod 16 is provided, so that the second movable plate 19 can move back and forth. When the second movable plate 19 moves back and forth, the rack 36 moves back and forth accordingly. The rack 36 is meshed with the auxiliary gear 33, so that the auxiliary gear 33 can rotate back and forth clockwise and counterclockwise, and then the mounting pipe 9 can swing left and right, so that water can fully contact the crushed waste paper, thereby improving the pulping effect.

[0030] When the rotating block 20 rotates, because the cross section of the rotating block 20 is square and matches the groove 23, the stirring shaft 21 can rotate accordingly, and when the second movable plate 19 moves back and forth, the stirring shaft 21 moves back and forth accordingly. When the stirring shaft 21 moves back and forth, the rotating block 20 always cooperates with the groove 23, so that the stirring shaft 21 can rotate and move back and forth at the same time, and finally the stirring rod 22 on the stirring shaft 21 can rotate and move back and forth at the same time, so that the water in the box body 1 and the crushed waste paper can be fully stirred, so that the waste paper can be fully pulped.

[0031] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
