A feeding port 3 is opened in the middle position of the top of the box cover 2. A feeding box 4 is provided on the top of the box cover 2. A feeding pipe 5 extending to the inside of the feeding port 3 is provided at the bottom end of the feeding box 4. A mobile feeding mechanism connected to the feeding box 4 is provided on the top of the box cover 2. A guide seat 6 is symmetrically installed on the inner wall of the box cover 2. A feeding channel 18 is formed between the two guide seats 6 and the box cover 2. Both guide seats 6 are trapezoidal structures.

[0021] The crushing mechanism includes rotating shafts 13 rotatably mounted inside the housing 1 and symmetrically arranged. Crushing rollers 14 are fixedly mounted on the two rotating shafts 13. One end of each rotating shaft 13 is connected to a gear 15 located outside the housing 1. The two gears 15 are meshed and connected. A motor 16 connected to one of the rotating shafts 13 is installed on the other side of the housing 1.

[0022] By starting the motor three 16, the motor three 16 will drive one of the rotating shafts 13 to rotate, and the rotating shaft 13 will cause the crushing roller 14 and the gear 15 on it to rotate synchronously. Through the meshing connection relationship between the two gears 15, the other gear 15 will rotate in the opposite direction, and then the gear 15 will cause the other rotating shaft 13 to drive the crushing roller 14 to rotate in the opposite direction, so that the two crushing rollers 14 can crush the kaolin falling through the blanking channel 18.

[0023] The mobile feeding mechanism includes a fixed plate 24 fixed to one side of the top of the box cover 2, a second motor 26 is installed on one side of the fixed plate 24, the output shaft of the second motor 26 is connected to the second screw rod 27, the outer sleeve of the second screw rod 27 is provided with a connecting seat 25 connected to the side wall of the feeding box 4, the connecting seat 25 is threadedly connected to the second screw rod 27, the feeding pipe 5 is in sliding contact with the inner wall of the feeding port 3, and the bottom end of the feeding box 4 is symmetrically embedded with balls in contact with the top of the box cover 2. The design of the ball effectively reduces friction;

[0024] Start motor 26, which drives screw rod 27 to rotate. Through the threaded connection between screw rod 27 and connecting seat 25 and the sliding relationship between feeding tube 5 and the inner wall of feeding port 3, feeding box 4 drives feeding tube 5 to move horizontally at the top of box cover 2, so that feeding tube 5 can move back and forth between two crushing rollers 14 to feed kaolin, effectively increasing the feeding area of ​​kaolin and realizing dispersed feeding of kaolin, solving the problem that kaolin feeding position is fixed and it is easy to accumulate in one place, thereby reducing its crushing efficiency. Thus, this design effectively improves the crushing efficiency of kaolin.

[0025] The pushing mechanism includes a guide plate 19 fixed to the inner wall of the box body 1. The guide plate 19 is a triangular structure. A groove 20 is formed at the bottom end of the guide plate 19. A motor 17 is installed on the outer wall of the box body 1. The output shaft of the motor 17 is connected to a screw rod 21 located inside the groove 20. The outer portion of the screw rod 21 is provided with a slide 22 slidably connected to the inner wall of the groove 20. The slide 22 is threadedly connected to the screw rod 21. The bottom end of the slide 22 is fixed to a scraper plate 23 slidably connected to the filter plate 9.

[0026] After the two crushing rollers 14 crush the kaolin, it will fall on the filter plate 9, and then it can be screened through the through holes on the filter plate 9, so that the kaolin that passes through the through holes falls into the collection box 8 for collection. The design of the guide plate 19 can achieve the diversion of the kaolin, and can protect the screw rod 21, so as to prevent the kaolin from falling on the screw rod 21 and affecting the movement of the slide 22. Then start the motor 3 16, the motor 3 16 drives the screw rod 21 to rotate, and the screw rod 21 is connected to the slide 22 through the threaded connection relationship and The sliding connection between the slide 22 and the groove 20 will cause the slide 22 to drive the scraper plate 23 to slide on the filter plate 9, so that the scraper plate 23 pushes the kaolin to change its position, effectively improving the screening efficiency of the kaolin. At the same time, the reciprocating movement of the scraper plate 23 facilitates the scraper plate 23 to push the kaolin that has not passed through the through hole to move, so that it falls into the collection box 2 11 through the discharge chute 10, and then it is convenient for the staff to put the kaolin in the collection box 2 11 into the feeding box 4 again, and crush and screen it again.

[0027] The implementation principle of a screening device for kaolin processing in the embodiment of the present application is as follows:

[0028] Start the second motor 26, which drives the second screw rod 27 to rotate. Through the threaded connection relationship between the second screw rod 27 and the connecting seat 25 and the sliding relationship between the feeding pipe 5 and the inner wall of the feeding port 3, the feeding box 4 drives the feeding pipe 5 to move horizontally on the top of the box cover 2, so that the feeding pipe 5 can move back and forth between the two crushing rollers 14 to feed the kaolin, effectively increasing the feeding area of ​​the kaolin and realizing the dispersed feeding of the kaolin. This solves the problem that the kaolin feeding position is fixed, causing it to easily accumulate in one place and reduce its crushing efficiency. Therefore, this design effectively improves the crushing efficiency of the kaolin.

[0029] The motor 3 16 is started, and the motor 3 16 drives one of the rotating shafts 13 to rotate. The rotating shaft 13 causes the crushing roller 14 and the gear 15 on it to rotate synchronously. Through the meshing connection relationship between the two gears 15, the other gear 15 is caused to rotate in the opposite direction. Then, the gear 15 causes the other rotating shaft 13 to drive the crushing roller 14 to rotate in the opposite direction, so that the two crushing rollers 14 can crush the kaolin falling through the drop channel 18.

[0030] After the two crushing rollers 14 crush the kaolin, it will fall on the filter plate 9, and then it can be screened through the through holes on the filter plate 9, so that the kaolin that passes through the through holes falls into the collection box 8 for collection. The design of the guide plate 19 can achieve the diversion of the kaolin, and can protect the screw rod 21, so as to prevent the kaolin from falling on the screw rod 21 and affecting the movement of the slide 22. Then start the motor 3 16, the motor 3 16 drives the screw rod 21 to rotate, and the screw rod 21 is connected to the slide 22 through the threaded connection relationship and The sliding connection between the slide 22 and the groove 20 will cause the slide 22 to drive the scraper plate 23 to slide on the filter plate 9, so that the scraper plate 23 pushes the kaolin to change its position, effectively improving the screening efficiency of the kaolin. At the same time, the reciprocating movement of the scraper plate 23 facilitates the scraper plate 23 to push the kaolin that has not passed through the through hole to move, so that it falls into the collection box 2 11 through the discharge chute 10, and then it is convenient for the staff to put the kaolin in the collection box 2 11 into the feeding box 4 again, and crush and screen it again.

[0031] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
