Description

Technical Field

[0001] This invention relates to the field of automatic feeding equipment technology, specifically to an integrated automatic feeding and sorting equipment for ceramic grinding balls. Background Technology

[0002] Ceramic grinding balls are key grinding media in equipment such as ball mills and stirred mills. They are widely used in the material grinding process in industries such as ceramics, coatings, and pigments. When producing or using ceramic grinding balls, it is often necessary to classify them according to their diameter to meet the needs of different grinding processes.

[0003] A ceramic grinding ball sorting device is disclosed in publication number CN117000596A, relating to the field of ceramic ball sorting technology. The device includes a base, a support frame fixedly connected to the upper surface of the base, a feed cylinder fixedly connected to the support frame, and a sorting box fixedly connected to the upper surface of the base. The feed end of the sorting box is located below the discharge port of the feed cylinder. Sliding grooves are provided on the inner walls of the front and rear sides of the sorting box, and push plates are slidably connected to the sliding grooves in the left-right direction. The bottom surface of the sorting box has several screening holes of different sizes, with the hole diameter increasing sequentially along the flow direction of the grinding balls in the sorting box. A collection box is fixedly connected to the lower surface of the base and communicates with the sorting box. This invention can control the moving speed of the ceramic grinding balls within the sorting box and uses cushioning bags to buffer the sorted ceramic grinding balls, preventing them from being damaged by collision during their fall.

[0004] The inventors of this application discovered in their research that the core defect of the prior art is that, although the sorting device can sort according to the particle size of the ceramic grinding balls when in use, it cannot sort ceramic grinding balls of appropriate particle size for feeding according to actual production needs. Summary of the Invention

[0005] This invention provides an integrated automatic feeding and sorting device for ceramic grinding balls, which solves the problem that after the ceramic grinding balls are sorted, it is impossible to feed compliant ceramic grinding balls according to the grinding requirements, and achieves the effect of integrated sorting and feeding.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated automatic feeding and sorting device for ceramic grinding balls, comprising a housing, a feeding hopper fixedly connected to the top of the housing, a material plate fixedly connected inside the housing, a sorting cylinder rotatably connected inside the housing, a first linkage gear fixedly connected to one end of the sorting cylinder penetrating inside the housing, a motor frame fixedly connected to one side of the housing, a servo motor fixedly connected to the output end of the motor frame, a motor pulley fixedly connected to the output end of the servo motor, a power roller rotatably connected inside the housing, a first pulley fixedly connected to one end of the power roller, a first belt connected to the outside of the first pulley via the external transmission of the motor pulley, a first power bevel gear fixedly connected to the outside of the power roller, one side of the first power bevel gear meshing with one side of the first linkage gear, a solid rod rotatably connected inside the housing, a second hollow rod rotatably connected to the outside of the solid rod, a first hollow rod rotatably connected to the outside of the second hollow rod, and a sorting plate fixedly connected to the top of each of the solid rod, the second hollow rod, and the first hollow rod.

[0007] By adopting the above technical solution, after the ceramic grinding balls are poured into the equipment along the feed hopper, they are divided into three sizes: large, medium, and small. They are sorted on the top of the sorting plate. By rotating the sorting plate as needed, the compliant ceramic grinding balls can be controlled to be fed, achieving the effect of automatic feeding and sorting in one.

[0008] Preferably, a locking block is fixedly connected to one end of the solid rod, the second hollow rod, and the first hollow rod; a second power bevel gear is fixedly connected to the outside of the first linkage gear; a linkage rod is rotatably connected inside the housing; one end of the linkage rod passes through the inside of the housing and is fixedly connected to the second linkage bevel gear; one side of the second linkage bevel gear meshes with one side of the second power bevel gear; and a ratchet is fixedly connected to the outside of the linkage rod.

[0009] Preferably, a telescopic rod is fixedly connected inside the housing, a locking block is fixedly connected to the bottom of the telescopic rod, and a tension spring is fixedly connected to the top of the locking block through the inside of the housing.

[0010] Preferably, a pressing rod is fixedly connected to the top of the card block, the top of the pressing rod penetrates the interior of the housing, and a top block is fixedly connected to the top of the pressing rod.

[0011] Preferably, the top block is fixedly connected to a spring through the inside of the housing, and an abutment block is fixedly connected to the top of the top block.

[0012] By adopting the above technical solution, it is possible to conveniently change the discharge and feeding status of the sorting plate. After the equipment is started, the sorting plate is mechanically locked, which effectively prevents the sorting plate from changing its status during operation. It is also more stable than traditional electronic locking and solves the problem of locking failure after power failure.

[0013] Preferably, a discharge hopper is fixedly connected to the bottom of the casing, and a transmission roller is rotatably connected inside the discharge hopper. A second pulley is fixedly connected to one end of the transmission roller.

[0014] Preferably, the second belt is externally connected to the second pulley via a pressing rod, and a transmission bevel gear is fixedly connected to the other end of the transmission roller.

[0015] Preferably, an anti-blocking pipe is fixedly connected to the bottom of the discharge hopper, and a shaft is rotatably connected inside the discharge hopper.

[0016] Preferably, a rotating bevel gear is fixedly connected to the top of the shaft, the bottom of the rotating bevel gear meshes with one side of the transmission bevel gear, and an anti-blocking rod is fixedly connected to the outside of the shaft.

[0017] Preferably, a valve is installed at the bottom of the anti-blocking pipe, and the output end of the valve is connected to a negative pressure pipe.

[0018] By adopting the above technical solution, the transmission structure enables one motor to drive multiple devices, allowing the anti-blocking rod to rotate synchronously during the sorting process of the servo motor-driven equipment. This keeps the accumulated ceramic grinding balls in motion, effectively preventing them from clogging the feeding pipe structure.

[0019] This invention provides an integrated automatic feeding and sorting device for ceramic grinding balls. It has the following advantages:

[0020] 1. This invention uses a servo motor to rotate a power roller via a transmission structure, which, in conjunction with bevel gear transmission, moves ceramic grinding balls at the top of a sorting cylinder. Based on the diameter of the holes in the sorting cylinder, smaller grinding balls fall onto the sorting plate first, and then grinding balls of different sizes fall onto their respective sorting plates. By rotating the sorting plate, the sorting of grinding balls and subsequent feeding are controlled, thereby achieving the effect of selecting ceramic grinding balls of appropriate sizes for feeding according to feeding requirements. This solves the problem that traditional automatic feeding equipment cannot sort grinding balls for feeding.

[0021] 2. In this invention, during the sorting process, the ratchet is continuously rotated by the linkage rod driven by a servo motor. The contact block is lowered by force and guided by the telescopic rod, causing the locking block to insert between the locking blocks, thereby locking the sorting plate. This allows the sorting state of the sorting plate to be easily changed before the equipment starts, and the sorting plate to be stably locked after the equipment starts. This solves the problem that the sorting plate is easily affected by the impact of ceramic grinding balls during equipment operation, which changes its sorting state.

[0022] 3. By setting up a transmission structure, the present invention enables the servo motor to start and the transmission roller to rotate in conjunction with it. The rotating bevel gear and the transmission bevel gear simultaneously cause the shaft to rotate. After the anti-blocking rod rotates inside the anti-blocking tube, it plays the role of moving the grinding balls. This solves the problem that after the valve of the feeding equipment is closed, a large number of grinding balls accumulate inside the pipe, and even after the valve is opened later, the ceramic grinding balls inside the equipment remain stationary and block the pipe.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see the appendix Figure 1 - Appendix Figure 10 This invention provides an integrated automatic feeding and sorting device for ceramic grinding balls, comprising a housing 1, a feeding hopper 2 fixedly connected to the top of the housing 1, a material plate 15 fixedly connected inside the housing 1, a sorting cylinder 11 rotatably connected inside the housing 1, one end of the sorting cylinder 11 penetrating the inside of the housing 1 and fixedly connected to a first linkage gear 14, a motor frame 8 fixedly connected to one side of the housing 1, a servo motor 9 fixedly connected to the output end of the motor frame 8, a motor pulley 21 fixedly connected to the output end of the servo motor 9, and a power roller 12 rotatably connected inside the housing 1. One end is fixedly connected to a first pulley 10. The outside of the first pulley 10 is connected to a first belt 22 through the external transmission of the motor pulley 21. The outside of the power roller 12 is fixedly connected to a first power bevel gear 13. One side of the first power bevel gear 13 meshes with one side of the first linkage gear 14. A solid rod 20 is rotatably connected inside the housing 1. A second hollow rod 19 is rotatably connected outside the solid rod 20. A first hollow rod 18 is rotatably connected outside the second hollow rod 19. A sorting plate 7 is fixedly connected to the top of the solid rod 20, the second hollow rod 19 and the first hollow rod 18 respectively.

[0036] Specifically, the servo motor 9 is started by external power supply, and the motor pulley 21 is driven to rotate. The first belt 22 drives the first pulley 10 to rotate. After the power roller 12 rotates as a whole, it drives the second power bevel gear 24 to rotate, which in turn drives the second linkage bevel gear 25 and the sorting cylinder 11 to rotate. The holes on the sorting cylinder 11 gradually increase in size starting from the material plate 15. The ceramic grinding balls are poured into the inside of the feed hopper 2 and roll along the material plate 15 to the top of the sorting cylinder 11. They are then moved as a whole by the sorting cylinder 11. The ceramic grinding balls with smaller particle sizes fall to the top of the sorting plate 7, while the ceramic grinding balls with larger particle sizes gradually move to the sorting cylinder 11 with larger hole diameters and fall. According to the particle diameter, the ceramic grinding balls are divided into large, medium, and small and fall onto the sorting plate 7. According to the subsequent grinding requirements, one end of the exposed part of the sorting plate 7 is rotated to rise, so that the ceramic grinding balls fall into the discharge hopper 3 for subsequent grinding machine feeding. The remaining ceramic grinding balls are discharged along the sorting plate 7.

[0037] Please see the appendix Figure 6 Appendix Figure 7 Appendix Figure 8 and attached Figure 9 A locking block 35 is fixedly connected to one end of the solid rod 20, the second hollow rod 19, and the first hollow rod 18. A second power bevel gear 24 is fixedly connected to the outside of the first linkage gear 14. A linkage rod 26 is rotatably connected inside the housing 1. One end of the linkage rod 26 passes through the inside of the housing 1 and is fixedly connected to the second linkage bevel gear 25. One side of the second linkage bevel gear 25 meshes with one side of the second power bevel gear 24. A ratchet 27 is fixedly connected to the outside of the linkage rod 26. A pressing rod 31 is fixedly connected to the top of the locking block 32. The top of the pressing rod 31 passes through the inside of the housing 1. A top block 28 is fixedly connected to the top of the pressing rod 31. A spring 29 is fixedly connected to the top block 28 through the inside of the housing 1. An abutment block 30 is fixedly connected to the top of the top block 28.

[0038] Specifically, after the servo motor 9 starts, the power roller 12 rotates, the second power bevel gear 24 drives the second linkage bevel gear 25 to rotate, the linkage rod 26 drives the ratchet 27 to rotate continuously, the ratchet 27 pushes the abutment block 30 down, the pressing rod 31 slides down and the locking block 32 is locked between the locking blocks 35, thereby locking the rotation of the sorting plate 7. During this process, the spring 29 is compressed, the tension spring 34 is stretched, and the telescopic rod 33 is extended. After the ratchet 27 stops rotating, the spring 29 and the tension spring 34 drive the abutment block 30 to insert into the gap of the ratchet 27, and the locking block 32 rises, so that the sorting plate 7 can rotate using the first hollow rod 18, the second hollow rod 19 and the solid rod 20.

[0039] Please see the appendix Figure 6 Appendix Figure 7 and attached Figure 10The bottom of the casing 1 is fixedly connected to the discharge hopper 3. The discharge hopper 3 is rotatably connected to the transmission roller 16. One end of the transmission roller 16 is fixedly connected to the second pulley 17. The outside of the second pulley 17 is connected to the second belt 23 through the external transmission of the pressing rod 31. The other end of the transmission roller 16 is fixedly connected to the transmission bevel gear 37. The bottom of the discharge hopper 3 is fixedly connected to the anti-blocking pipe 4. The discharge hopper 3 is rotatably connected to the shaft 38. The top of the shaft 38 is fixedly connected to the rotating bevel gear 36. The bottom of the rotating bevel gear 36 meshes with one side of the transmission bevel gear 37. The outside of the shaft 38 is fixedly connected to the anti-blocking rod 39. The bottom of the anti-blocking pipe 4 is equipped with a valve 5. The output end of the valve 5 is connected to the negative pressure pipe 6.

[0040] Specifically, after the servo motor 9 starts, the second belt 23 drives the second pulley 17 to rotate, the transmission roller 16 drives the transmission bevel gear 37 to rotate, and after the rotating bevel gear 36 rotates, the shaft 38 rotates inside the discharge hopper 3, and the anti-blocking rod 39 pushes the ceramic grinding ball to always be in an active state, effectively preventing the ceramic grinding ball from blocking the pipeline structure after it stops.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
