Description

Technical Field

[0001] This utility model belongs to the field of abrasive processing technology, specifically relating to a conical abrasive processing device for a paper mill. Background Technology

[0002] Conical refiners are a common type of refining equipment in the paper industry. Their core components are a pair of conical refining discs, the upper and lower discs mounted opposite each other. The disc surfaces are typically engraved with specific teeth, grooves, or other types of abrasive patterns to increase friction, shearing, and kneading effects on the fibers. Due to the numerous abrasive patterns on the discs, casting is often used in their manufacturing process. During casting, after pouring and cooling, the formed discs need to be cleaned of sand. However, cleaning the discs with abrasive patterns on the inner side is more complicated due to the smaller space and closer spacing between the patterns, making the cleaning process more prone to omissions and affecting the precision of the refining die.

[0019] Please see Figures 1-5This utility model provides the following technical solution: It includes a supporting side plate 1, an electric telescopic rod 3, a first rotating motor 31, and a second rotating motor 42. A positioning platform 2 is provided on one side of the supporting side plate 1, and a top plate 12 is provided on the top of one side of the supporting side plate 1. The electric telescopic rod 3 is fixedly connected to the bottom of the top plate 12, and the first rotating motor 31 is fixedly connected to the bottom of the electric telescopic rod 3. A conical block 4 is provided at the bottom of the first rotating motor 31, and a sand-cleaning assembly 5 is slidably connected to one side of the conical block 4. The sand-cleaning assembly 5 includes a connecting housing 51 and a movable... Block 52 and wire brush 521 are connected to the connecting housing 51 by several springs 511. The wire brush 521 is located on the side of the movable block 52 away from the connecting housing 51. The rotating motor 42 is located at the top of the conical block 4. The top of the conical block 4 is provided with a threaded rod 43. The top of the connecting housing 51 is provided with a connecting rod 53. The end of the connecting rod 53 away from the connecting housing 51 is provided with a connecting plate 531. The connecting plate 531 is provided with a threaded hole 532. The threaded rod 43 is located inside the threaded hole 532.

[0020] This implementation plan includes a supporting side plate 1, an electric telescopic rod 3, a first rotating motor 31, and a second rotating motor 42. A positioning platform 2 is provided on one side of the supporting side plate 1. The positioning platform 2 is fixed in position to the supporting side plate 1, and both the top and bottom of the positioning platform 2 are open, allowing the conical grinding disc to be directly placed on top of the positioning platform 2. A top plate 12 is provided on the top of one side of the supporting side plate 1, and the top plate 12 is fixedly connected to the supporting side plate 1 and perpendicular to it. The electric telescopic rod 3 is fixedly connected to the bottom of the top plate 12, with one end fixedly connected to the top plate 12. The electric telescopic rod 3 extends and retracts at the bottom of the top plate 12. The first rotating motor 31 is fixedly connected to the bottom of the electric telescopic rod 3. When the electric telescopic rod 3 extends or retracts, the first rotating motor 42... The position of motor 31 will rise or fall. A conical block 4 is located at the bottom of motor 31. As the electric telescopic rod 3 extends and retracts, the conical block 4 rises and falls accordingly, thus adjusting its height. When the grinding disc with the grinding pattern on the inner side is located at the top of the positioning platform 2, the extension of the electric telescopic rod 3 allows the conical block 4 to descend to the inner side of the grinding disc. Motor 31 can then rotate the conical block 4 within the grinding disc. A sand-cleaning component 5 is slidably connected to one side of the conical block 4. When the conical block 4 rotates, the sand-cleaning component 5 also rotates. The sand-cleaning component 5 includes a connecting housing 51, a movable block 52, and a wire brush 521. The wire brush 521 cleans the grinding disc through contact with it. The movable block 52 is connected to the connecting housing 51 by several springs 511. The elastic deformation of the springs 511 allows the distance between the movable block 52 and the connecting housing 51 to increase or decrease. The wire brush 521 is located on the side of the movable block 52 away from the connecting housing 51. When the sand-cleaning assembly 5 rotates with the conical block 4 inside the grinding disc, the wire brush 521 contacts the inner side of the grinding disc. The second rotating motor 42 is located at the top of the conical block 4 and is in an inclined state. A threaded rod 43 is provided at the top of the conical block 4, and the threaded rod 43 is also in an inclined state and perpendicular to the second rotating motor 42. The rotation of the threaded rod 43 can be controlled by the second rotating motor 42, and the inclination angle of the threaded rod 43 is the same as the inclination angle of the side of the conical block 4. A connecting rod 53 is provided on the top of the connecting housing 51. The connecting rod 53 is fixedly connected to the connecting housing 51 and is parallel to the side of the threaded rod 43 and the conical block 4. There is a gap between the connecting rod 53 and the conical block 4. A connecting plate 531 is provided at the end of the connecting rod 53 away from the connecting housing 51. The connecting plate 531 is fixedly connected to the connecting rod 53. Therefore, the connecting plate 531, the connecting rod 53, and the sand-cleaning assembly 5 will move synchronously. A threaded hole 532 is provided on the connecting plate 531. The threaded rod 43 is located inside the threaded hole 532. When the threaded rod 43 rotates, the connecting plate 531 will translate along the threaded rod 43 through the connection between the threaded rod 43 and the threaded hole 532, thereby driving the sand-cleaning assembly 5 to slide up and down along the side of the conical block 4.When the conical block 4 is located inside the grinding disc, the rotation of the conical block 4 and the threaded rod 43 causes the sand-cleaning component 5 to rotate and slide up and down in the gap between the conical block 4 and the grinding disc. This helps to ensure the contact area between the sand-cleaning component 5 and the grinding disc, reducing the number of dead corners that affect sand cleaning due to the small space inside the grinding disc and the small distance between the grinding grooves, thus improving the sand-cleaning efficiency of the sand-cleaning component 5 on the grinding disc.

[0021] A connecting frame 11 is provided at the bottom of one side of the supporting side plate 1, and the positioning platform 2 is fixedly connected to the connecting frame 11; the connecting frame 11 is fixedly connected to the supporting side plate 1, and the distance between the positioning platform 2 and the supporting side plate 1 is fixed through the connection of the connecting frame 11.

[0022] The top plate 12 and the connecting frame 11 are located on the same side, and the electric telescopic rod 3 corresponds to the position of the positioning platform 2; the cone block 4 is located above the positioning platform 2, and the distance between the cone block 4 and the positioning platform 2 will increase or decrease as the electric telescopic rod 3 extends or retracts.

[0023] A groove 41 is provided on the outer side of the conical block 4, and the connecting housing 51 is slidably connected to the groove 41. The groove 41 allows the sand cleaning component 5 and the conical block 4 to be slidably connected, and the sliding direction of the sand cleaning component 5 matches the side tilt angle of the conical block 4.

[0024] The threaded rod 43 and the connecting rod 53 are parallel to each other and do not contact each other; the threaded rod 43 and the connecting rod 53 will not interfere with each other. During the sliding process of the connecting rod 53 and the sand cleaning component 5, the connecting rod 53 is always parallel to the side of the threaded rod 43 and the conical block 4.

[0025] A limiting block 431 is provided at the end of the threaded rod 43 away from the rotating motor 42. The size of the limiting block 431 is larger than the threaded hole 532. The limiting block 431 is fixedly connected to the threaded rod 43. By limiting the connection of the limiting block 431, the separation of the connecting plate 531 and the threaded rod 43 can be avoided.

[0026] The movable block 52 is slidably connected to the inner side of the connecting housing 51, and several springs 511 are located on the inner side of the connecting housing 51. Because the inner side of the grinding disc is uneven, the sliding of the movable block 52 and the connecting housing 51 allows the wire brush 521 to pass through the convex part of the grinding groove, while the springs 511 allow the wire brush 521 to enter the concave part of the grinding groove.

[0027] The working principle and usage process of this utility model are as follows: In use, firstly, the grinding disc with the grinding pattern located on the inner side needs to be placed on the top of the positioning platform 2. Then, by extending the electric telescopic rod 3, the conical block 4 can be lowered to the inner side of the grinding disc, and the sand cleaning component 5 will be located in the gap between the conical block 4 and the grinding disc. Then, by rotating the first motor 31 and the second motor 42, the conical block 4 and the threaded rod 43 can be rotated, and the threaded rod 43 will rotate clockwise and counterclockwise in sequence, thereby making the sand cleaning component 5 move in the gap between the conical block 4 and the grinding disc. The spring 511 allows the wire brush 521 to enter the concave part of the grinding pattern, and by sliding the movable block 52 and the connecting housing 51, the wire brush 521 can pass through the convex part of the grinding pattern. Through the contact between the wire brush 521 and the grinding pattern, the grinding pattern can be cleaned.
