Description

A grinding device for pulping blades Technical Field

[0001] This utility model relates to the technical field of blade grinding equipment, and in particular to a pulping blade grinding device. Background Technology

[0002] Pulping, also known as beating, involves mechanically shearing the pulp fibers in water to change their shape and impart certain properties to the pulp, ensuring that the final paper meets the expected quality requirements. During the pulping process, the blades cut the fibers for an extended period, causing wear and affecting the shearing effect. However, blade polishing is still often done manually, which cannot guarantee polishing quality and precision. Furthermore, manual operation carries risks, increasing the risk of processing accidents and endangering personnel safety. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a grinding blade grinding device in response to the above-mentioned technical deficiencies. The device uses a longitudinal adjustment component to drive the blade to move back and forth to achieve the grinding operation. At the same time, the transverse adjustment component can quantitatively drive the blade to move towards the grinding workpiece, adjust the contact force, and ensure the grinding quality and grinding accuracy, thus replacing manual operation.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific Implementation Method 1: As shown in Figures 1-7, a pulping blade grinding device includes: a support 1, a grinding component 101 on the left side of the support 1, a longitudinal adjustment component 2 on one side of the grinding component 101 on the support 1, and a transverse adjustment component 3 on the right side of the support 1; a blade holder 4, which is slidably connected to the longitudinal adjustment component 2, and an extension plate 401 slidably connected to the transverse adjustment component 3 is provided below the blade holder 4; wherein, the grinding component 101 includes a power motor and a grinding wheel, the power motor drives the grinding wheel to rotate, and the grinding operation of the blade is completed, and the working surface of the grinding wheel can be an inclined surface, thereby satisfying the grinding operation of the blade edge;

[0028] The blade is installed on the tool holder 4, and then the longitudinal adjustment component 2 is activated to drive the tool holder 4 to move back and forth in the front and back directions. During the displacement, it contacts the grinding part 101 to achieve the grinding operation of the blade. At the same time, depending on the situation, the transverse adjustment component 3 can be made to connect with the longitudinal adjustment component 2 to drive the tool holder 4 closer to the grinding part 101 in a quantitative manner, thereby ensuring the grinding depth of the blade. Compared with manual operation, the grinding accuracy is higher, and the tool holder speed is stable during the back and forth movement, which can effectively ensure the grinding quality.

[0029] In a preferred embodiment, as shown in Figures 2 and 3, the longitudinal adjustment component 2 includes a first threaded rod 201 and a sliding platform 202. Both ends of the first threaded rod 201 are connected to the bracket 1 via rotating shafts, and first guide rods 203 are installed above and below the first threaded rod 201, respectively. The sliding platform 202 is threadedly connected to the first threaded rod 201 and slidably connected to the first guide rods 203. A track 204 slidably connected to the tool holder 4 is provided above the sliding platform 202, and a rack 205 is provided on the right side. By adding a motor to the end of the first threaded rod 201, the forward and reverse rotation of the motor controls the reciprocating movement of the sliding platform 202. The rack 205 is partially connected to the transverse adjustment component 3.

[0030] In a preferred embodiment, as shown in Figures 3-5, the lateral adjustment assembly 3 includes a combined shaft 5 and a folding plate 6. The combined shaft 5 is mounted on a bracket 1, and one end is provided with a gear 7 that meshes with a rack 205. A hydraulic cylinder 8 is provided on the bracket 1 on one side of the combined shaft 5. The folding plate 6 is threadedly connected to the combined shaft 5 and slidably connected to the extension plate 401 above. Under normal conditions, the combined shaft 5 is in a separated state. During the reciprocating motion of the rack 205, the shaft at the gear 7 rotates accordingly, while the right half of the combined shaft 5 remains stationary. When it is necessary to quantitatively push the tool holder 4 to move towards the grinding piece 101, the hydraulic cylinder 8 drives the right half of the combined shaft 5 to engage with the left half, thereby realizing the transmission of power.

[0031] In a preferred embodiment, as shown in Figures 4-6, the combined shaft 5 includes a first shaft body 501 and a second threaded rod 502. The middle part of the first shaft body 501 is connected to the bracket 1 by a rotating shaft, the left side is connected to the gear 7 by a key, and the right side is provided with a contact plate 503. The left end of the second threaded rod 502 is provided with a displaceable pressing plate 504, which is connected to a hydraulic cylinder 8. When power transmission docking is required, the hydraulic cylinder 8 drives the pressing plate 504 to move and make contact with the contact plate 503. Then, after the rack 205 meshes with the gear 7, it drives the first shaft body 501 to rotate, thereby realizing the power transmission. The threaded connection between the folding plate 6 and the second threaded rod 502 can push the folding plate 6 to move towards the grinding part 101 during rotation, thereby completing the position adjustment.

[0032] In a preferred embodiment, as shown in Figure 6, the hydraulic cylinder 8 is provided with a clamping plate 801, and the clamping plate 801 has a groove in the middle. The width of the groove is equal to the edge of the pressing plate 504, so that the rotation of the pressing plate 504 is not affected when the pressing plate 504 is pushed to move.

[0033] In a preferred embodiment, as shown in Figures 6 and 7, the left end of the second threaded rod 502 is provided with a guide strip 505, and the inner circle of the pressing plate 504 is provided with a corresponding guide groove. By connecting the two, the displacement of the pressing plate 504 can be realized, while satisfying the transmission of torque.

[0034] In a preferred embodiment, as shown in Figures 4 and 5, a second guide rod 601 is provided on the folding plate 6, and both ends of the second guide rod 601 are connected to the bracket 1. When the second threaded rod 502 drives the folding plate 6 to move, the second guide rod 601 can play a guiding and positioning role, thereby improving the stability of the displacement of the folding plate 6.

[0035] In a preferred embodiment, as shown in Figure 5, a sliding groove 602 is provided above the folding plate 6. The sliding groove 602 is slidably connected to the extension plate 401. While ensuring the connection, it will not affect the forward and backward movement of the knife table 4.
