Description

Technical Field

[0001] This utility model belongs to the field of papermaking grinding disc technology, and particularly relates to a disc grinding disc. Background Technology

[0002] The grinding discs in papermaking are the core components of the pulp refiner in the pulping section of the papermaking industry. They are considered consumable parts, and their service life directly affects the quality of pulp, paper, and production efficiency. The grinding discs are the heart of the refiner, directly exerting shearing, crushing, stretching, and frictional forces on the pulp fibers to change the fiber morphology and meet the requirements for papermaking adaptability. The grinding discs mechanically process the pulp fibers suspended in water, giving them the characteristics required for production on the papermaking machine, thereby ensuring that the produced paper achieves the expected quality. However, in the existing technology, the grinding disc material is not good enough. Therefore, a disc grinding disc is proposed.

[0003] For example, Chinese patent CN202766900U discloses a papermaking disc grinding plate, which has multiple grinding zones, each with multiple raised grinding teeth arranged in parallel, and the gap between the grinding teeth is 0.1mm.

[0004] The aforementioned patent has the following problems:

[0005] Compared to existing grinding discs, the materials used are not of sufficient quality, failing to guarantee extended lifespan and thus reducing working time while increasing manufacturing costs. Furthermore, existing grinding discs are inconvenient to assemble and replace; if one part is damaged, the entire disc must be replaced, wasting resources and significantly reducing the usability of other parts, thus impacting grinding efficiency. Therefore, we propose a disc grinding disc. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a disc grinding wheel that achieves the effect of high-quality grinding wheel material and convenient splicing of grinding wheels.

[0007] In view of this, the present invention provides a disc grinding disc, including a first grinding disc, and further comprising: a second grinding disc movably mounted on one side of the first grinding disc; a polyethylene layer fixedly disposed inside the first grinding disc and the second grinding disc; a silicon carbide layer fixedly disposed at the bottom of the polyethylene layer; a high-speed steel layer fixedly disposed at the bottom of the silicon carbide layer; a hook and loop fastener face movably mounted between the first grinding disc and the second grinding disc; a hook and loop fastener face movably mounted on one side of the hook and loop fastener face; fixing plates movably mounted at both ends of the hook and loop fastener face; connecting plates fixedly mounted on both sides of the fixing plates; and a connecting bolt penetrating through the interior of the connecting plates.

[0008] Based on the above structure, the first grinding disc can be spliced ​​with the second grinding disc. The polyethylene layer, renowned for its excellent wear resistance, impact resistance, chemical stability, and low coefficient of friction, makes it an ideal grinding disc material for papermaking machinery. Next, the silicon carbide layer, with its high hardness, excellent wear resistance, high temperature resistance, and corrosion resistance, and the high-speed steel layer, further enhances the strength of the first and second grinding discs. This combination of high-quality grinding disc materials increases their service life and working time while reducing manufacturing costs. The first and second grinding discs are then fixed by attaching the hook and loop sides of the Velcro. A fixing plate and connecting plate further limit the position of the hook and loop sides, and connecting bolts secure them to prevent movement. This combination allows for easy splicing and replacement of the grinding discs. When a portion of the grinding disc is damaged, it can be removed via the hook and loop sides for easy replacement, reducing workload and not affecting the grinding disc's working efficiency.

[0009] Preferably, the second grinding disc has a through-hole for ventilation, and a protective layer is fixedly installed inside the ventilation hole to facilitate ventilation of the device.

[0010] Preferably, a grinding block is fixedly installed on the surface of the first grinding disc. The grinding block is made of polyurethane material and enhances the grinding process.

[0011] Preferably, protective layers are movably installed on both sides of the connecting plate, and the protective layers are made of rubber material, which facilitates the cracking of the first grinding disc.

[0012] Preferably, a mounting plate is movably mounted on one side of the grinding block, and mounting holes are opened through the surface of the mounting plate. Mounting bolts are fixedly installed on the other side of the mounting holes, so that the mounting plate can easily fix the device to the machine.

[0013] Preferably, the mounting plate is made of stainless steel, and the stainless steel material is used to reinforce the mounting plate material.

[0014] The beneficial effects of this utility model are:

[0015] 1. This grinding disc can be spliced ​​with a first grinding disc and a second grinding disc. The polyethylene layer is known for its excellent wear resistance, impact resistance, chemical stability and low coefficient of friction, making it an ideal grinding disc material in papermaking machinery. Then, the silicon carbide layer is used for its high hardness, excellent wear resistance, high temperature resistance and corrosion resistance. Finally, the high hardness of the high-speed steel layer is used to strengthen the strength of the first and second grinding discs. When used together, the grinding disc materials are of high quality, which can increase the service life of the grinding disc, increase the working time of the grinding disc, and reduce the manufacturing cost of the grinding disc.

[0016] 2. This grinding disc can be fixed by attaching the hook and loop sides of the hook and loop fasteners. Then, a fixing plate and a connecting plate are used to limit the position of the hook and loop sides. Finally, a connecting bolt can be used to fix it in place to prevent the hook and loop sides from shaking. When used together, the grinding discs are easy to splice and replace. When a part of the grinding disc is damaged, it can be removed through the hook and loop sides for easy replacement, reducing workload and not affecting the working efficiency of the grinding disc.
