Description

Technical Field

[0001] The utility model relates to the technical field of base paper processing, in particular to a refiner with good refining effect for base paper. Background Art

[0002] In the papermaking industry, the production of base paper is a crucial link. The quality of base paper directly determines the quality of the final paper products. In order to improve the quality of base paper, it is usually subjected to pulping treatment. Pulping treatment can improve the surface roughness of base paper, enhance its strength, and improve its ink absorption, thereby improving the overall quality of paper products. Pulping treatment generally uses a pulper to refine the original base paper. Usually, the base paper is sent to a refining chamber and then refined by a rotating grinding disc or grinding roller. During the refining process, the surface of the grinding disc or grinding roller will produce friction and shear force on the base paper, making the base paper fibers loose and broomed, thereby improving the performance of the base paper.

[0003] However, existing refiners often have some problems, such as poor refining effect and low efficiency, which limit the further improvement of base paper quality and increase production costs. For this reason, we propose a refiner with good refining effect for base paper. Utility Model Content

[0022] Furthermore, a rotating block 13 is fixedly connected to the bottom of the refining cylinder 4, and a rotating groove 14 is opened at the bottom of the inner wall of the supporting base 3. The rotating block 13 is movably inserted in the rotating groove 14. The rotation of the rotating block 13 in the rotating groove 14 can better allow the refining cylinder 4 to be separated from the refining cylinder cover 11. By rotating the threaded rod 6 to drive the sliding block 7 to move upward, the sliding block 7 drives the refining cylinder cover 11 to move upward through the connecting block 8, so that raw materials can be easily put into the refining cylinder cover 11.

[0023] Furthermore, the driving device 20 includes a driving motor 9, a bevel gear 10 and a stirring rotating shaft 17. The driving motor 9 is fixedly connected to one end of the connecting block 8 close to the pulping cylinder cover 11, and the bevel gear 10 is fixedly connected to the rotating shaft of the driving motor 9. The upper surface of the pulping cylinder cover 11 is rotatably connected to the stirring rotating shaft 17, and the top of the stirring rotating shaft 17 is fixedly connected to a second bevel gear 10, and the two bevel gears 10 are meshed.

[0024] Furthermore, the refining device 12 includes a threaded connection ring 15 and a refining plate 16. The lower end of the refining cylinder cover 11 is fixedly connected with the threaded connection ring 15 corresponding to the inner cavity of the refining cylinder 4.

The two refining plates of the refining plate 16 extend downward in a spirally staggered rotation state, and the surface of the refining plate in the refining plate 16 is a rough surface.

[0025] Furthermore, the refining device 12 also includes a support frame 18 and a friction spring 19. The support frame 18 is fixedly connected to the inner wall of the refining cylinder 4.

[0026] Working principle: When the device is needed to refine the base paper, first rotate the refining cylinder 4, and the refining cylinder cover 11 and the refining cylinder 4 are separated by rotating the refining cylinder 4. The rotating block 13 at the bottom is clamped in the rotating groove 14 and rotated, so that the refining cylinder 4 will not move in the horizontal position when it is separated from the refining cylinder cover 11. Then rotate the threaded rod 6, and drive the sliding block 7 to move upward by rotating the threaded rod 6. The sliding block 7 drives the refining cylinder cover 11 to move upward through the connecting block 8, and put the base paper into the refining cylinder 4. Rotate the threaded rod 6 again, and make the refining cylinder cover 11 cover the refining cylinder 4 tightly through the upper operation; turn on the drive motor 9, and drive the first bevel gear to rotate by the drive motor 9 10 rotates, the first bevel gear 10 rotates to drive the second bevel gear 10 on the stirring rotating shaft 17 to rotate, and the second bevel gear 10 drives the pulping sheet 16 at the lower end of the stirring rotating shaft 17 to rotate through the stirring rotating shaft 17, and starts to refine the base paper. The special shape of the pulping sheet 16 can increase the friction between the raw material and the raw material with the cooperation of the friction spring 19 on the support frame 18 when refining the base paper, ensuring that the raw material is evenly ground over a larger area during the grinding process, which helps to improve the comminution efficiency and production performance of the equipment, making the base paper fibers looser, thereby improving the performance of the base paper and enhancing the quality of the final paper product.
