Description

Technical Field

[0001] The invention relates to the technical field of papermaking grinding discs, and more specifically to a plug-in grinding disc for pulping in pulp and papermaking processing. Background Art

[0002] The grinding discs in the wood-based panel and pulp and paper industries are components that directly separate cellulose fibers. While separating the fibers, they also wear out. Whether the mill can give full play to its technical performance and economic indicators depends largely on the wear state of the grinding discs. In the process of separating cellulose fibers, the grinding discs will experience friction wear, fatigue wear, abrasive wear and corrosive wear. After the grinding discs are worn, the cutting edge becomes blunt and the gap becomes larger, causing the grinding discs to fail and be removed from the machine.

[0003] The shortcomings of the existing technology: However, most of the existing grinding discs are of integral structure. During the grinding operation, if the grinding area of ​​the grinding disc is damaged, the grinding disc needs to be replaced frequently, otherwise it will affect the papermaking quality. The existing grinding disc fixing method is to position it with bolts. The multiple bolt mounting holes opened on the grinding disc will occupy part of the grinding area on the grinding disc, and it is also inconvenient to disassemble and install the grinding disc. For this reason, we propose a plug-in grinding disc for pulping in pulp and papermaking processing. Summary of the invention

The inner wall of the female groove is provided with a plurality of second grooves, and the second balls are arranged in the second grooves.

[0012] Technical effects and advantages of the present invention:

[0013] 1. The present invention controls the slider to slide forward in the slide groove, thereby driving the positioning block to move forward, so that the positioning block is inserted into the positioning hole provided on the surface of the grinding plate body, thereby completing the installation and positioning effect of the grinding plate body. At the same time, when the grinding plate body is positioned and inserted, the adjacent male connector of the grinding plate body will be inserted into the female groove. After the grinding plate body is fixed, the male connector will be completely inserted into the female groove, so that the connectivity between adjacent grinding plate bodies is improved, and it is more stable during processing and use.

[0014] 2. The present invention uses a spring to drive the push block to apply thrust to the guide block, and then the thrust is transmitted to the grinding plate body, and then the threaded rod is thrusted by transmission, so that the spring indirectly squeezes the threaded rod. When vibration occurs during the operation of the equipment, the threaded rod can be effectively prevented from loosening, so that the stability of the grinding plate body when it is fixed is improved. At the same time, after the positioning assembly releases the positioning of the grinding plate body, the grinding plate body can be pushed out to the surroundings of the fixed carrier under the action of the spring, so that the grinding plate body is more convenient to disassemble and replace.

[0015] 3. In the present invention, the friction between the three surfaces of the male connector and the female groove that cooperate with each other is reduced through the action of the first ball and the second ball, thereby avoiding the grinding plate bodies from getting stuck when plugged in and connected, and ensuring that the pushing force of the spring on the grinding plate body will not fail and can be maintained all the time, so that the spring can indirectly squeeze the threaded rod all the time, which not only improves the stability of the grinding plate body when it is fixed, but also makes it smoother and more convenient to disassemble and assemble the grinding plate body.
