Description

Technical Field

[0001] The utility model relates to the field of pulp processing, in particular to a paper shredding device for pulp processing. Background Art

[0002] At present, when paper is processed, the shredder is usually used to shred the shredded paper, and the shredded paper is collected and transported to the next stage to be mixed into pulp, and then the pulp is processed and bleached for subsequent processing. During the shredding process, the shredder will generate a lot of dust and debris, which will float in the air. This dust will eventually fall near the shredder, and the operator must clean it up after the processing is completed. In addition, since the two processes of shredding and pulping are separate, the staff must also transport the shredded paper. Utility Model Content

[0003] The utility model aims to provide a paper shredding device for pulp processing to reduce the falling of shredded paper during the shredding process, reduce the transfer actions of operators, and reduce their work intensity.

[0004] In order to solve the above technical problems, the specific solution adopted by the utility model is:

[0005] A paper shredding device for pulp processing comprises a lower box body with an open top, an upper box body is arranged on the top of the lower box body, a mixing device for mixing paper pulp is arranged inside the lower box body, a shredding device for shredding paper is arranged inside the upper box body, the shredding device comprises a second rotating rod symmetrically mounted on the inner wall of the upper box body and connected to rotate by a motor, a shredding roller for shredding paper is arranged on the second rotating rod, and second gears meshing with each other are arranged on the two second rotating rods, and the bottom of the upper box body is open to discharge the shredded paper into the lower box body for mixing.

[0006] The mixing device includes a first rotating rod symmetrically arranged on the inner wall of the lower box body and rotatably connected, the first rotating rod is provided with stirring blades at intervals, the two first rotating rods are provided with first gears meshing with each other, a motor for driving the first rotating rod to rotate is provided on the side of the lower box body, the other end of the first rotating rod extends to the outside of the lower box body, a first driving wheel is provided on the extended end of the first rotating rod, one end of the second rotating rod extends to the outside of the upper box body and corresponds to the first rotating rod, a second driving wheel is provided on the extended end of the second rotating rod, and a slot is provided on the second driving wheel and the first driving wheel, and a transmission belt is installed inside the slot.

[0007] The top of the upper box body is symmetrically provided with material guide plates, which are inclined toward between the two crushing rollers to form a material discharge chute.

[0008] A drainage pipe is arranged at the bottom of the lower box body, and a sealing cover connected by threads is arranged on the drainage pipe.

[0009] The top width of the lower box body is greater than the bottom width of the lower box body to form a material taking trough.

[0010] The tops of the material taking trough and the upper box body are both equipped with cover plates.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0012] By arranging a mixing device in the lower box body to mix the pulp, and by arranging a crushing device in the upper box body to crush the shredded paper, the shredded paper is directly discharged into the mixing device for pulp mixing after the shredding work is completed. Since the width of the lower box body is larger than that of the upper box body, the falling of the shredded paper is effectively reduced, and through the cooperation of the first driving wheel, the second driving wheel and the transmission belt, the mixing and crushing work can be completed by one motor. The utility model has a simple and reasonable structure, effectively reduces the carrying work of the operator, and reduces the falling of the shredded paper caused by the shredder during the shredding process.
