Technical Field

[0001] The utility model relates to the technical field of papermaking, in particular to a pulp supply mechanism for a papermaking machine. Background Art

[0002] Pulp is one of the important raw materials in the papermaking industry. It is used to produce various types of paper and paper products. It is a fibrous substance made by chemical or mechanical processing of plant materials with high cellulose content such as wood, waste paper, bamboo, etc. In the papermaking process, pulp is mixed, processed, formed, pressed and dried to finally be made into various types of paper, such as newsprint, manuscript paper, wrapping paper, toilet paper, specialty paper, etc. Different types of paper require different types and proportions of pulp to produce to meet market demand.

[0003] After searching, the patent number "CN219450254U" mentioned in the text that "the utility model discloses a pulp supply mechanism for a papermaking machine, including a pulp supply box, the lower end of which is provided with four supporting legs symmetrically arranged in pairs, and also includes a shredding mechanism arranged in the pulp supply box for shredding the clumping pulp, the shredding mechanism includes a shredding rod rotatably connected to the pulp supply box, the shredding rod is provided with a plurality of shredding blades, and the outer wall of the pulp supply box is provided with a driving shaft. The utility model realizes the shredding of the clumping pulp by setting the shredding mechanism, and under the filtering action of the filtering mechanism, the shredded clumping pulp flows from the discharge pipe to the papermaking machine, thereby avoiding the clumping pulp. The problem of blockage of the discharge pipe is avoided, which ensures the normal transportation of the pulp and further ensures the working efficiency of the papermaking machine. When it is used, the clumping pulp is chopped up by the setting of the shredding mechanism, and the shredded clumping pulp flows from the discharge pipe to the papermaking machine under the filtering action of the filtering mechanism, thereby avoiding the problem of blockage of the discharge pipe caused by the clumping pulp, ensuring the normal transportation of the pulp and further ensuring the working efficiency of the papermaking machine. However, the device cannot effectively handle the pulp debris attached to the inner wall, and a layer of pulp wall with uneven thickness will be formed, which hinders the normal operation of the device, which will cause the device to be unable to effectively mix and homogenize the pulp, thereby reducing the working efficiency of the papermaking machine.

[0004] To this end, we provide a paper machine pulp supply mechanism to solve the above problems. Utility Model Content

[0014] It can be seen from the above technical scheme that the present application provides a pulp supply mechanism for a papermaking machine. First, pulp is poured into the main body through the feed port, and the control motor is started to drive the control rod to rotate. The blade follows the rotation to cut the clumped pulp in the pulp. Then the screw is fixed to fix the blade on the mounting frame, which is convenient for disassembly and assembly, and also convenient for adjusting the blade cutting angle or replacing blades of different models.

Then the drive motor is started to drive the drive shaft to rotate, and the drive gear is controlled to follow the rotation to rotate the meshing transmission gear, so that the C-frame rotates, and the cover and the C-frame provide a certain limit support for the rotating connection. Finally, the scraper scrapes off the sticky pulp on the inner wall to effectively prevent the formation of a pulp wall. The evenly mixed pulp is input into the papermaking machine through the valve control at the bottom of the main body, completing the use process of a papermaking machine pulp supply mechanism.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The pulp debris attached to the inner wall is removed by the cleaning mechanism to prevent the formation of pulp wall, which hinders the normal operation of the device, so that the device can effectively mix and homogenize the pulp.
