Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, to a pulping cutter disc structure for a pulper. Background Technology

[0002] Pulping discs are an important component of papermaking equipment and accessories, mainly used in the pulping process of papermaking equipment to break down pulp boards, waste paper, damaged paper, and deink and purify pulp. Through a specific structural design, they effectively improve pulping efficiency and quality.

[0003] The existing publicly available technology, application number CN202120588643.8, describes a mixing cutter disc for a hydraulic pulper. This disc, without damaging the blade structure of the cutter disc body, incorporates wear-resistant parts at the wear areas of the blades, thereby reducing wear on the cutter disc body. A fixing strip is welded to the blades, and the wear-resistant strip is fixed to the fixing strip by a fixing component. The wear-resistant strip is replaced according to its actual wear condition, thus extending the service life of the cutter disc body. Replacement is convenient and quick, and maintenance costs are low.

[0004] However, the above-mentioned patent still has certain drawbacks in use: although it extends the service life of the cutter head body by setting wear-resistant strips, when the blades, guide blades or even the cutter head structure on the cutter head body are damaged, the entire structure needs to be replaced, which not only increases the difficulty of maintenance, but also increases the maintenance costs and reduces the effectiveness of the device.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a pulping cutter disc structure for a pulper is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a pulping cutter head structure for a pulper according to an embodiment of the present utility model includes a cutter head body 1 and a limiting plate 11. A plurality of sets of snap-fit ​​grooves 6 are provided around the outer surface of the cutter head body 1. A plurality of sets of blades 2 are snapped into the inside of the snap-fit ​​grooves 6. A flying knife 3 is connected to one side surface of the blade 2 by bolts. A docking groove 12 is provided in the middle of the top surface of the blade 2. A guide knife 4 is snapped into the inside of the docking groove 12.

[0031] In one embodiment, a limiting plate 11 is bolted to the top of the cutter head body 1. The limiting plate 11 is provided to shield the blade 2 and the snap-fit ​​groove 6, thereby improving the fixing effect of the blade 2.

[0032] In one embodiment, a mounting groove 7 is provided at the middle position of the surface of the cutter disc body 1 and the middle position of the surface of the limiting disc 11. Several sets of mounting holes 9 are evenly provided on the surface of the mounting groove 7. The mounting groove 7 and the mounting holes 9 are provided to facilitate the connection between the cutter disc body 1 and the pulper, thereby facilitating the subsequent use of the cutter disc and achieving the purpose of pulping.

[0033] In one embodiment, a number of sets of second fastening holes 8 are provided on the outer surface of the cutter head body 1 and the outer surface of the limiting plate 11.

[0034] In one embodiment, a plurality of third fastening holes 10 are uniformly provided at the top position of one side surface of the wing 2 and the top position of one side surface of the flying knife 3.

[0035] In one embodiment, several sets of first fastening holes 5 are provided inside the docking groove 12 and on the surface of the guide knife 4.

They are all used to facilitate the connection and fastening between structures, and will not be described in detail here.

[0036] In one embodiment, the surface of the guide knife 4 is provided with an L-shaped groove. The L-shaped groove is provided so that the guide knife 4 can abut against the surface of the limiting disk 11 after the limiting disk 11 is installed. This prevents the guide knife 4 from being unable to be positioned above the wing 2 after the limiting disk 11 limits and fixes one end of the wing 2, thereby affecting the subsequent guiding effect on the pulp.

[0037] In one embodiment, a T-shaped structure is provided at one end of the blade 2 for snap-fitting. The T-shaped structure is provided to snap the blade 2 into the snap-fit ​​groove 6, thereby realizing the connection operation between the blade 2 and the cutter head body 1.

[0038] Working principle: In actual use, personnel can install the cutter head body 1 through the mounting holes 9 and mounting slots 7 for convenient subsequent pulping. When the cutter head body 1 is damaged after prolonged use or requires maintenance, the limiting plate 11 can be disassembled through the second fastening hole 8 on its surface. At this time, multiple snap-fit ​​slots 6 on the surface of the cutter head body 1 can be exposed, making it convenient for personnel to disassemble and replace the multiple snap-fit ​​blades 2. Moreover, the flying knife 3 and the guide knife 4 on the surface of the blade 2 are also detachable structures. Therefore, when damage occurs, only the damaged parts need to be replaced, and the intact parts can still be used normally. This effectively reduces maintenance losses and improves maintenance convenience. The device as a whole has the advantages of convenient maintenance, low maintenance losses, and targeted maintenance.
