Description

Technical Field

[0001] This invention relates to the field of ceramic ball sorting technology, specifically to a ceramic grinding ball sorting device. Background Technology

[0002] The production of ceramic grinding balls generally includes the following steps: First, after determining the core and raw materials, the core is poured into a ball rolling machine; second, the feeding and slurry addition speeds are controlled to ensure close contact between the raw materials and the core, allowing the balls to grow into a spherical shape; third, when the balls have grown to the required size uniformly, feeding and slurry addition are stopped, and finally, the balls are smoothed and shaped. In the production process of existing ceramic balls, some ceramic balls made from materials such as silicon carbide, silicon nitride, alumina, and zirconium oxide are smaller than the standard ceramic ball volume. Therefore, the subsequent ceramic ball sorting operation is particularly important.

Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0028] The present invention provides the following embodiments.

[0029] Example 1

[0030] This invention provides a ceramic grinding ball sorting device, such as... Figures 1-2As shown, the system includes a base 1, a support frame 2 fixedly connected to the upper surface of the base 1, a feed cylinder 3 fixedly connected to the support frame 2, a sorting box 4 fixedly connected to the upper surface of the base 1, the feed end of the sorting box 4 being located below the discharge port of the feed cylinder 3, sliding grooves 5 being provided on the inner walls of the front and rear sides of the sorting box 4, a pusher plate 6 being slidably connected in the sliding grooves 5 along the left and right direction, a number of screening holes 7 of different sizes being provided on the bottom surface of the sorting box 4, the diameter of the screening holes 7 increasing sequentially along the flow direction of the grinding balls in the sorting box 4, and a collection box 8 fixedly connected to the lower surface of the base 1, the collection box 8 being connected to the sorting box 4.

[0031] Preferably, the collection box 8 is provided with a number of collection slots 9, and a cushioning soft bag 10 is provided above each collection slot 9. The cushioning soft bag 10 is fixedly connected to the lower surface of the sorting box 4. The inlet of each cushioning soft bag 10 is connected to a screening hole 7 of a certain size, and the outlet of each cushioning soft bag 10 is connected to a different collection slot 9.

[0032] Preferably, the discharge port of the feed cylinder 3 is hinged to a control cover 11 on the right side, and an installation plate 12 is fixedly connected to the outer wall of the feed cylinder 3. An installation plate 2 13 is fixedly connected to the outer wall of the control cover 11. The installation plate 12 and the installation plate 2 13 are correspondingly arranged, and a spring 14 is fixedly connected between the installation plate 12 and the installation plate 2 13.

[0033] Preferably, a second spring 15 is fixedly connected to the upper part of the inner wall on the right side of the sorting box 4, and a trigger plate 16 is fixedly connected to the left end of the second spring 15. The trigger plate 16 is slidably connected to the inner wall of the sorting box 4. A connecting seat 17 is fixedly connected to the lower surface of the control cover 11, and a connecting rope 18 is attached to the connecting seat 17. The other end of the connecting rope 18 is fixedly connected to the left side wall of the trigger plate 16.

[0034] The beneficial effects of the above technical solution are as follows:

[0035] When sorting ceramic grinding balls, all ceramic grinding balls are first poured into the feed cylinder 3. The control cover 11 blocks the outlet of the feed cylinder 3 under the action of spring 14. When the pusher plate 6 moves to the rightmost side of the sorting box 4, the upper part of the pusher plate 6 pushes the trigger plate 16. The trigger plate 16 pulls the control cover 11 through the connecting rope 18, causing the control cover 11 to open and allowing the ceramic grinding balls in the feed cylinder 3 to fall into the sorting box 4. After the pusher plate 6 leaves the rightmost side of the sorting box 4, the trigger plate 16 resets under the action of spring 2 15. The control cover 11, which loses the tension of the connecting rope 18, closes under the action of spring 14. The ceramic grinding balls that fall into the sorting box 4 are pushed by the pusher plate 6 and pass through the screening holes 7 of different sizes in sequence. The ceramic grinding balls that meet the size requirements fall from the screening holes 7 into the buffer bag 10. After being buffered, the ceramic grinding balls fall from the outlet of the buffer bag 10 into the collection tank 9.

[0036] The automatic feeding of ceramic grinding balls is achieved by controlling the opening and closing of the control cover 11 through the pusher plate 6. This eliminates the need for operators to frequently add ceramic grinding balls, saving a significant amount of labor. Only a small number of ceramic grinding balls participate in the sorting at a time, ensuring accurate sorting results. The pusher plate 6 moves the ceramic grinding balls, controlling their movement speed within the sorting box. This prevents the ceramic grinding balls from moving too fast and missing the appropriate screening holes 7, thus avoiding screening errors. It also prevents the ceramic grinding balls from colliding with each other and causing damage. The cushioning bag 10 cushions the sorted ceramic grinding balls, preventing them from colliding and being damaged during their fall.

[0037] This invention solves the following problems mentioned in the background art: such as the directional sorting equipment and implementation method for composite ceramic spherical particles disclosed in CN115283239A, which has the following problems: 1. During the sorting process of ceramic grinding balls, the movement speed of the grinding balls on the sieve plate cannot be controlled; 2. The inlet of the collection chamber lacks a buffer structure, and the ceramic grinding balls falling from the sieve plate will hit the ceramic grinding balls in the collection chamber, which may damage some qualified products.

[0038] Example 2

[0039] Based on Example 1, such as Figures 3-6 As shown, it also includes multiple polishing devices 50, each polishing device 50 being connected to the discharge port of a collection tank 9, and the polishing device 50 being fixedly connected to the lower surface of the collection box 8.

[0040] Preferably, the polishing device 50 includes a polishing seat 19, which is fixedly connected to the lower surface of the collection box 8. A feed pipe 20 is provided inside the polishing seat 19. The feed pipe 20 is vertically arranged. The upper end of the feed pipe 20 is connected to the outlet of the collection tank 9. The lower end of the feed pipe 20 is connected to a conveying pipe 21. An electric telescopic rod 22 is provided at the rear end of the conveying pipe 21. Two mounting slots 23 are symmetrically arranged on the left and right sides of the conveying pipe 21 inside the polishing seat 19. The outlet of the conveying pipe 21 is connected to the polishing chamber 51. Two sets of polishing components are symmetrically arranged on the left and right sides inside the polishing chamber 51.

[0041] Preferably, the polishing assembly includes a mounting frame 24, which is fixedly connected to the bottom surface of the polishing cavity 51. A clamping box 25 is slidably connected inside the mounting frame 24. A motor 26 is installed inside the clamping box 25. A clamping claw 27 is fixedly connected to the output end of the motor 26. A spring 28 is fixedly connected between the end of the clamping box 25 near the mounting frame 24 and the inner wall of the mounting frame 24.

[0042] Preferably, a mounting bracket 29 is fixedly connected to the top surface of the polishing chamber 51. The polishing assembly also includes a second sliding groove 30, which is disposed on the front side wall of the mounting bracket 29. A sliding block 31 is slidably connected in the sliding groove 30 along the vertical direction. A spring 32 is fixedly connected between the top surface of the sliding block 31 and the top surface of the sliding groove 30. A connecting post 33 is fixedly connected to the front side of the sliding block 31. An inclined plate 34 is fixedly connected to the top surface of the clamping box 25. The lower surface of the inclined plate 34 contacts the side of the connecting post 33. A connecting rod 35 is fixedly connected to the upper surface of the sliding block 31. The upper end of the connecting rod 35 is hinged to the upper end of the connecting rod 36. A third sliding groove 37 is provided on the connecting rod 36. A third connecting post 38 is fixedly connected to the mounting bracket 29 and is slidably connected in the third sliding groove 37.

[0043] Preferably, the material conveying assembly includes a baffle plate 39, which is L-shaped. The turning point of the baffle plate 39 is rotatably connected to the bottom surface of the mounting groove 23. One end of the baffle plate 39 extends into the material conveying pipe 21, and the other end of the baffle plate 39 is fixedly connected to a connecting post 40. A connecting rod 41 is hinged to one end of the clamping box 25 near the mounting frame 24. A sliding groove 42 is provided on the connecting rod 41, and the connecting post 40 is slidably connected in the sliding groove 42.

[0044] Preferably, a lifting plate 43 is fixedly connected to the lower surface of the mounting bracket 29, a spring 44 is fixedly connected to the lower surface of the lifting plate 43, a polishing plate 45 is fixedly connected to the lower end of the spring 44, a receiving groove 46 is provided on the lower surface of the polishing cavity 51, a spring 47 is fixedly connected to the bottom surface of the receiving groove 46, a support plate 48 is fixedly connected to the upper end of the spring 47, and a conical surface 49 is provided at both ends of the support plate 48, with the two conical surfaces 49 contacting the two clamping boxes 25 respectively.

[0045] The beneficial effects of the above technical solution are as follows:

[0046] 1. In the initial state, the ceramic grinding balls in the collection tank 9 fall into the feed pipe 20 through the discharge port of the collection tank 9. Since there is an electric telescopic rod 22 on one side of the lower end of the feed pipe 20 and a baffle plate 39 on the other side, only a single ceramic grinding ball enters the conveying pipe 21, and the rest of the ceramic grinding balls are arranged in the feed pipe 20.

[0047] 2. As the electric telescopic rod 22 extends, the ceramic grinding ball is pushed out after squeezing the baffle plate 39, causing the baffle plate 39 to rotate. This rotates the connecting rod 41 via the connecting column 2 40, causing the two clamping boxes 25 to move away from each other. This causes the support plate 48 to rise under the action of the spring 6 47, allowing the ceramic grinding ball to move on the support plate 48 between the two clamping claws 27. As the electric telescopic rod 22 retracts, the clamping boxes 25 move closer to each other under the action of the spring 3 28, clamping the ceramic grinding ball. At the same time, the baffle plate 39 returns to its initial position, preventing subsequent ceramic grinding balls from rolling into the polishing chamber 51. As the clamping boxes 25 move closer to each other, the support plate 48 is pressed into the receiving groove 46, causing the ceramic grinding ball to suspend in the air.

[0048] 3. When the clamping box 25 moves toward the corresponding mounting frame 24 (the two clamping boxes 25 move away from each other), the inclined plate 34 contacts the side of the connecting column 33, causing the sliding block 31 to move downward, and causing the end of the connecting rod 36 near the polishing plate 45 to move upward. The polishing plate 45 moves upward under the action of the spring 44, making it easier for the ceramic grinding ball to reach the designated position. When the clamping box 25 moves away from the corresponding mounting frame 24 (the two clamping boxes 25 move closer to each other), the sliding block 31, which is no longer pressed by the inclined plate 34, moves upward under the action of the spring 32, causing the end of the connecting rod 36 near the polishing plate 45 to move downward and press down the polishing plate 45, so that the polishing surface of the polishing plate 45 contacts the ceramic grinding ball.

[0049] 4. After the ceramic grinding ball is clamped, start the motor 26 to drive the ceramic grinding ball to rotate. The ceramic grinding ball contacts the polishing plate 45 to polish the surface of the ceramic grinding ball. After polishing is completed, stop the motor 26. When the next ceramic grinding ball moves to the working position, the previous ceramic grinding ball is pushed away from the working position and falls from the discharge port of the polishing seat 19.

[0050] 5. By setting up the polishing device 50, the ceramic grinding balls can be automatically polished after sorting, saving a lot of manpower. Through the cooperation of the electric telescopic rod 22 and the baffle plate 39, only one ceramic grinding ball enters the polishing chamber 51 each time, avoiding damage to the device caused by multiple balls entering at the same time. After the ceramic grinding ball is clamped, the support plate 48 is pressed into the receiving groove 46, preventing the support plate 48 from contacting the ceramic grinding ball and affecting its rotation. When replacing the ceramic grinding ball, the polishing plate 45 is moved upward to facilitate the movement of the ceramic grinding ball.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
