[0014] The present invention provides a grinding device for processing precision ceramic materials. It has the following beneficial effects: (1) In this invention, when the movable end of the elastic telescopic rod rotates continuously and disengages from the fixed block, then the feeding door quickly resets under the action of the first spring. By intermittently opening and resetting, the feeding can be reasonably controlled to reduce the wear between the mold and the workpiece, make the processed surface smoother, improve the quality of the finished product, and prevent the machine from being damaged due to excessive material entering. At the same time, when the shaped pull rod slides upward, it pulls the flap to start rotating. The rotating flap dumps the materials behind the feeding port to ensure that the materials can enter the machine body through the feeding port without manual operation by the staff, improving the working efficiency. At the same time, when the push rod slides, it pushes the materials that may be blocked at the feeding port to maintain a smooth working state, improving the overall working efficiency and enhancing the operation safety, enabling the operator to produce with more confidence and preventing the machine from being damaged due to material blockage.

[0015] (2) In this invention, when the feeding door closes, the cover plate starts to slide to enclose the crushing dish, ensuring that the first crushing hammer and the second crushing hammer can more effectively concentrate the impact force, improving the crushing efficiency, ensuring that the ceramic materials are fully crushed, and preventing the ceramic materials from scattering everywhere due to the impact force during crushing and damaging the inside of the machine body. At the same time, when the blocking rod rotates, it pushes the larger ceramic materials that fall to the bottom of the crushing dish and cannot enter the grinding pipe through continuous rotation to continue to contact the first crushing hammer and the second crushing hammer for crushing, ensuring that the ceramic materials can be crushed to a certain size and will not block the grinding pipe, making the grinding effect more stable, helping to improve the consistency and precision of the ceramic products, and improving the working efficiency.

[0016] (3) In this invention, when the pressing column rotates, it rolls the falling ceramic materials again to ensure that the ceramic materials are ground to a certain precision, helping to improve the shape and size distribution of the ceramic particles and making them more uniform, preventing some ceramic materials from not reaching the required size after grinding and resulting in a reduction in the yield rate. At the same time, when the movable door moves, it opens the channel at the bottom of the collection dish, enabling the ceramic materials to enter the inside of the collection box through the channel. The movable door will only open when the collection box is located at the bottom of the collection dish, ensuring that the ceramic materials can be completely collected, simplifying the operation process, reducing the risk of operation errors, and preventing the ceramic materials from leaking without being collected, thus keeping the working environment clean and safe. When the push plate rotates, it drives the scraping rod to start rotating through the connecting rod. When the movable door opens, the rotating scraping rod scrapes the ceramic materials at the bottom of the collection dish to ensure that the materials can flow smoothly when the movable door opens, reducing the risk of blockage caused by the accumulation of ceramic materials at the bottom of the collection dish.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The elastic telescopic rod 401 is fixedly installed on the circumferential surface of the rotating shaft 301. The feeding door 402 is slidably installed at one end of the feeding port 4 close to the machine body 1. The fixed block 403 is fixedly installed on the back of the feeding door 402. The flap 404 is rotatably installed at the bottom of the inner wall of the feeding port 4. The first chute 405 is opened at the front of the feeding door 402. One end of the U-shaped pull rod 406 close to the feeding door 402 is slidably installed inside the first chute 405. One end of the U-shaped pull rod 406 close to the flap 404 is rotatably installed at the top of the flap 404. When the movable end of the elastic telescopic rod 401 continuously rotates and disengages from the fixed block 403, then the feeding door 402 quickly resets under the action of the first spring. By intermittently opening and resetting, the feeding can be reasonably controlled, which can reduce the wear between the mold and the workpiece, make the processing surface smoother, improve the quality of the finished product, and prevent the machine from being damaged due to excessive material entering.

[0021] The feeding limiting device further includes a first slider 407, a second slider 408, a rotating rod 409 and a push rod 410. The first slider 407 is slidably installed on the inner wall of the feeding port 4. The second slider 408 is slidably installed on the inner wall of the feeding port 4. The first slider 407 and the second slider 408 are connected by the rotating rod 409. The push rod 410 is fixedly installed at the bottom of the second slider 408. By sliding the push rod 410, the material that may block the feeding port 4 can be pushed, maintaining a smooth working state, improving the overall working efficiency and enhancing the operation safety at the same time, enabling the operator to produce more reassuringly and preventing the machine from being damaged due to material blockage.

[0022] The surface of the movable end of the elastic telescopic rod 401 in contact with the fixed block 403 is set as an inclined surface. The first chute 405 is an inclined upward chute. The bottom of the first slider 407 is set as an inclined surface. A first spring is arranged between the feeding door 402 and the machine body 1. A second spring is arranged between the first slider 407 and the feeding port 4. By setting the inclined surface, it is ensured that the movable end of the elastic telescopic rod 401 can smoothly pass through the fixed block 403. By opening the inclined upward chute, it is ensured that the U-shaped pull rod 406 can move upward along the track when sliding in the chute. By setting the inclined surface, it is ensured that the first slider 407 can be more easily pushed. By setting the first spring, it is ensured that the feeding door 402 can achieve self-resetting. By setting the second spring, it is ensured that the first slider 407 can achieve self-resetting.

[0023] During the operation of this embodiment: First, place the ceramic material to be ground into the feed inlet 4. Then, start the motor 3 so that the rotating shaft 301 starts to rotate driven by the motor 3. The rotation of the rotating shaft 301 drives the elastic telescopic rod 401 to start rotating. Under the action of centrifugal force during the rotation of the elastic telescopic rod 401, the movable end of the elastic telescopic rod 401 extends. The extension of the movable end of the elastic telescopic rod 401 pushes the fixed block 403 during continuous rotation. The fixed block 403 drives the feed door 402 to start moving under the push. When the feed door 402 opens to the specified position, it stops moving. Since the movable end of the elastic telescopic rod 401 is disengaged from the fixed block 403 during continuous rotation, then the feed door 402 quickly resets under the action of the first spring. By intermittently opening and resetting, the feeding can be reasonably controlled, which can reduce the wear between the grinding tool and the workpiece, make the processed surface smoother, improve the quality of the finished product, and prevent the machine from being damaged due to excessive material entering; while the feed door 402 is opening, the U-shaped pull rod 406 slides inside the first chute 405. When the U-shaped pull rod 406 slides, it moves upward to pull the flap 404 to start rotating. The rotation of the flap 404 dumps the material behind the feed inlet 4 to ensure that the material can enter the machine body 1 through the feed inlet 4 without manual operation by the staff, improving the work efficiency. At the same time, the rotation of the flap 404 pushes the first slider 407 to start sliding. The sliding of the first slider 407 drives the second slider 408 to start sliding through the rotating rod 409. The sliding of the second slider 408 drives the push rod 410 to start sliding. The sliding of the push rod 410 pushes the material that may be blocked at the feed inlet 4, maintaining a smooth working state, improving the overall work efficiency and enhancing the operation safety, enabling the operator to produce more confidently and preventing the machine from being damaged due to material blockage.

[0024] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a crushing and grinding device is provided inside the machine body 1, and a collecting device is provided at the bottom of the machine body 1.

The grinding knife 509 is fixedly installed at the bottom of the rotating shaft 301. When the feeding door 402 is closed, the cover plate 501 starts to slide to seal the crushing dish 506, ensuring that the crushing hammer one 504 and the crushing hammer two 505 can more effectively concentrate the impact force, improving the crushing efficiency, ensuring that the ceramic material is fully crushed, and preventing the ceramic material from scattering everywhere due to the impact force and damaging the inside of the machine body 1 during crushing.

[0025] The cover plate 501 is fixedly installed on the back of the slider three 503. The chute two 502 is opened as a chute inclined upward. By fixedly installing, it is ensured that the slider three 503 can drive the cover plate 501 to move together when moving. By opening the chute inclined upward, it is ensured that the slider three 503 can move upward along the track when sliding in the chute.

[0026] The collecting device includes a collecting dish 601, a fixed door 602, a fixed column 603, a material distribution plate 604, a pressing column 605, a scraping plate 606, and a fixed rod 607. The collecting dish 601 is fixedly installed at the bottom of the machine body 1. The fixed door 602 is fixedly installed at the bottom of the collecting dish 601. The fixed column 603 is fixedly installed on the top of the fixed door 602. The material distribution plate 604 is fixedly installed on the top of the fixed column 603.

The fixed rod 607 is fixedly installed at the bottom of the grinding knife 509. By rotating the pressing column 605, the falling ceramic material is rolled again, ensuring that the ceramic material is ground to a certain precision, helping to improve the shape and size distribution of the ceramic particles and making them more uniform, and preventing some ceramic materials from not reaching the required size after grinding and resulting in a reduction in the yield rate.

[0027] The collecting device further includes a sliding column 608, a movable door 609, a long rod 610, a cross bar 611, a push plate 612, a scraping rod 613 and a connecting rod 614. The sliding column 608 is slidably mounted on the circumferential surface of the fixed column 603. The movable door 609 is rotatably mounted at the bottom of the sliding column 608. The long rod 610 is fixedly mounted at the bottom of the movable door 609. The cross bar 611 is fixedly mounted at the bottom of the long rod 610. The push plate 612 is fixedly mounted on the circumferential surface of the sliding column 608. The scraping rod 613 is slidably mounted on the inner wall of the collecting dish 601. The push plate 612 is connected to the scraping rod 613 through the connecting rod 614. When the push plate 612 rotates, it drives the scraping rod 613 to start rotating through the connecting rod 614. When the movable door 609 is opened, the scraping rod 613 rotates to scrape the ceramic material located at the bottom of the collecting dish 601, ensuring that the material can flow smoothly when the movable door 609 is opened, and reducing the risk of blockage caused by the accumulation of ceramic material at the bottom of the collecting dish 601.

[0028] The bottom of the cross bar 611 is provided with an inclined surface, and the surface of the material distribution plate 604 in contact with the scraping plate 606 is provided with an inclined surface. By setting the inclined surface, it is ensured that the collecting box 7 can push the cross bar 611 more easily when moving, and by setting the inclined surface, it is ensured that the ceramic material can slide down smoothly.

[0029] When this embodiment works: while the feeding door 402 is opened, the slider three 503 slides inside the chute two 502. The sliding of the slider three 503 drives the cover plate 501 to start sliding. The sliding of the cover plate 501 opens the crushing dish 506 so that the material can enter the crushing dish 506 for crushing. When the feeding door 402 is closed, the cover plate 501 starts to slide to close the crushing dish 506, ensuring that the first crushing hammer 504 and the second crushing hammer 505 can more effectively concentrate the impact force, improving the crushing efficiency, ensuring that the ceramic material is fully crushed, and preventing the ceramic material from scattering everywhere due to the impact force during crushing and damaging the inside of the machine body 1; while the rotating shaft 301 drives the first crushing hammer 504 and the second crushing hammer 505 to crush, it drives the blocking rod 507 to start rotating. The rotating of the blocking rod 507 pushes the larger ceramic material that has fallen to the bottom of the crushing dish 506 and cannot enter the grinding tube 508 through continuous rotation to continue to contact the first crushing hammer 504 and the second crushing hammer 505 for crushing, ensuring that the ceramic material can be crushed to a certain size and will not block the grinding tube 508, making the grinding effect more stable, helping to improve the consistency and precision of the ceramic products, improving the work efficiency, and preventing the ceramic material from being too large to enter the grinding tube 508 and causing blockage.

[0030] When the ceramic material passes through the grinding tube 508, the grinding knife 509 rotates to drive the fixed rod 607 to start rotating. The rotation of the fixed rod 607 pushes the pressing column 605 and the scraping plate 606 to rotate together. The rotation of the pressing column 605 re-rolls the falling ceramic material to ensure that the ceramic material is ground to a certain precision, which helps to improve the shape and size distribution of the ceramic particles, making them more uniform, and preventing some ceramic materials from failing to reach the required size after grinding, resulting in a reduction in the yield rate. Subsequently, the scraping plate 606 scrapes the ceramic material, causing the ceramic material to fall into the collection dish 601 through the material distribution plate 604. When there is a collection box 7 at the bottom of the collection dish 601, the collection box 7 will push the cross bar 611 to start moving. The movement of the cross bar 611 pushes the long rod 610 to start moving. The movement of the long rod 610 pushes the movable door 609 to start moving. The movement of the movable door 609 opens the channel at the bottom of the collection dish 601, allowing the ceramic material to enter the interior of the collection box 7 through the channel. The movable door 609 will only open when the collection box 7 is located at the bottom of the collection dish 601, ensuring that the ceramic material can be completely collected, simplifying the operation process, reducing the risk of operation errors, and preventing the leakage of ceramic materials without being collected, thereby maintaining the cleanliness and safety of the working environment. The movement of the movable door 609 pushes the sliding column 608 to start moving. The movement of the sliding column 608 drives the push plate 612 to start moving. The push plate 612 moves into contact with the continuously rotating scraping plate 606. The continuous rotation of the scraping plate 606 pushes the push plate 612 to start rotating. The rotation of the push plate 612 drives the scraping rod 613 to start rotating through the connecting rod 614. When the movable door 609 is opened, the scraping rod 613 will scrape the ceramic material located at the bottom of the collection dish 601 to ensure that the material can flow smoothly when the movable door 609 is opened, reducing the risk of blockage caused by the accumulation of ceramic materials at the bottom of the collection dish 601.
