[0002] Polishing powders are typically composed of components such as cerium oxide, aluminum oxide, silicon oxide, iron oxide, zirconium oxide, and chromium oxide. Different materials have different hardnesses and chemical properties in water, thus their applications vary. Generally, cerium oxide polishing powder is used for polishing glass and silicon-containing materials, aluminum oxide polishing powder is used for polishing stainless steel, and iron oxide can also be used for glass, but at a slower speed and is often used for polishing softer materials. Tin oxide is commonly used for polishing stone, and chromium oxide is commonly used for polishing ceramic tiles.
[0003] Polishing often requires the use of screening devices for processing. However, most existing screening devices use a single screen plate, which is not suitable for classifying and screening polishing powder. Furthermore, there may be clumps of raw material accumulating on the surface of the screen plate, resulting in incomplete screening of polishing powder and reducing the screening efficiency.

[0022] Reference Figure 1-4 A grading and screening device for polishing powder processing includes a screening box 1. The feeding and discharging are existing technologies and will not be described in detail here. Two symmetrically arranged uprights 2 are installed at the bottom of the screening box 1. The two uprights 2 are connected to a screening mechanism. The screening mechanism includes a first screening frame 6, a second screening frame 7, and a third screening frame 8. The first screening frame 6, the second screening frame 7, and the third screening frame 8 are stacked sequentially from bottom to top. An annular seat 9 is welded to the top edge of the first screening frame 6, the second screening frame 7, and the third screening frame 8. The annular seats 9 on the first screening frame 6 and the third screening frame 8 are connected to the uprights 2 through the uprights. The annular seat 9 on the second screening frame 7 is provided with a sliding opening. The inner side wall of the sliding opening is slidably sleeved with the outer side wall of the upright 2. A return spring 10 is sleeved on the outer side wall of the upright 2. The two ends of the return spring 10 are fixedly connected to the outer side wall of the upright 2 and the outer side wall of the annular seat 9 on the second screening frame 7, respectively, to play the role of shock absorption and reset.
[0023] The bottom of the first screening frame 6 is connected to the top of the docking plate 4 by multiple support rods 5. The bottom of the first screening frame 6, the second screening frame 7 and the third screening frame 8 are all provided with screening holes. The diameter of the screening holes on the first screening frame 6, the second screening frame 7 and the third screening frame 8 increases sequentially from bottom to top to ensure that polishing powder of different particle sizes can be separated step by step. Two symmetrically arranged first vibrating plates 11 are fixedly connected to the inner side wall of the second screening frame 7, and two symmetrically arranged second vibrating plates 12 are fixedly connected to the inner side wall of the first screening frame 6. These vibrating plates help disperse the material during vibration and reduce the probability of clogging of the screening holes.
[0024] A vibrator 3 is fixedly connected to the bottom of the screening box 1. A docking plate 4 is provided on the top of the vibrator 3. The docking plate 4 is connected to the screening mechanism and is used to transmit vibration. A drive motor 13 is fixedly connected to the outer wall of the screening box 1. The drive motor 13 is connected to a crushing mechanism. The crushing mechanism includes an output shaft 14 fixedly connected to the output end of the drive motor 13. The output shaft 14 passes through the side wall of the screening box 1 and the side wall of the third screening frame 8. A crushing blade 15 is fixedly sleeved on the outer wall of the output shaft 14 located in the third screening frame 8 to ensure that the material entering the screening frame is of appropriate size.
[0025] The crushing mechanism is connected to a driving mechanism via a transmission mechanism. The transmission mechanism includes a first pulley fixedly sleeved on the outer wall of the output shaft 14. Two sets of symmetrically arranged fixed plates 17 are fixedly connected to the top of the screening box 1. Rotating rods 16 are rotatably connected to the side walls of the two fixed plates 17. A second pulley is fixedly sleeved on the outer wall of the rotating rod 16. The first pulley and the second pulley are connected by a transmission belt 20 to realize the transmission of power.
[0026] The driving mechanism includes a cam 18 fixedly sleeved on the outer wall of the rotating rod 16. Two symmetrically arranged lifting rings 23 are fixedly connected to the outer wall of the annular seat 9 on the second screening frame 7. The side wall of the screening box 1 is provided with a lead wire port 21. A guide roller 22 is fixedly connected to the outer wall of the screening box 1. The lifting rings 23 are connected to a traction line 19. The traction line 19 passes through the lead wire port 21 and the guide roller 22 and rests on the surface of the cam 18. A retaining ring is provided at the edge of the cam 18 to ensure that the traction line 19 will not detach from the surface of the cam 18. When the cam 18 rotates, the traction line 19 will pull the second screening frame 7, and under the action of the return spring 10, it will make it reciprocate in the vertical direction, thereby enhancing the screening effect.
[0027] The specific working principle of this utility model is as follows:
[0028] In actual operation, when this device is used, the output shaft 14 is first started to rotate by the drive motor 13. The output shaft 14 is not only fixedly connected to the crushing blades 15 in the crushing mechanism, but also fixedly sleeved on the outside of it. As the output shaft 14 rotates, the crushing blades 15 will rotate at high speed inside the top layer of the grading and screening equipment for polishing powder processing, effectively crushing large particles that enter this layer and preventing large pieces of material from entering subsequent screening steps. At the same time, the second pulley, which is connected to the first pulley by the transmission belt 20, also rotates, thereby causing the rotating rod 16 fixedly connected to the pulley to move. This movement will drive the cam 18 fixedly sleeved on it to make periodic eccentric movements.
[0029] Meanwhile, a vibrator 3 installed inside the screening box 1 drives the screening mechanism to vibrate up and down via a connecting plate 4. This screening mechanism consists of a first screening frame 6, a second screening frame 7, and a third screening frame 8, arranged from bottom to top in ascending order of aperture size, thereby achieving the sorting of polishing powder from large to small. The bottom of the first screening frame 6 is fixed to the connecting plate 4 by a support rod 5, while the second screening frame 7 and the third screening frame 8 are connected to each other by a vertical rod 2 and an annular seat 9 welded to its top. Under the action of vibration, each screen will sort the material in sequence, and the smaller particle size material will pass through the larger screen holes and continue to be conveyed to the next level until the grading is completed. The two lifting rings 23 located on the outside of the second screening frame 7 are connected to the guide rollers 22 located on the outside of the screening box 1 via the traction line 19, and move vertically guided by the cam 18. With the help of the return spring 10, they provide continuous elastic restoring force. When the second screening frame 7 moves up and down, the first vibrating plate 11 hits the bottom of the third screening frame 8. When the second screening frame 7 moves down, the bottom of the second screening frame 7 hits the second vibrating plate 12 on the inner wall of the first screening frame 6. This causes the first screening frame 6, the second screening frame 7 and the third screening frame 8 to vibrate, which avoids the accumulation of polishing powder on the screening holes and the phenomenon of clogging the screening holes. This enhances the screening effect and stability of the first screening frame 6, the second screening frame 7 and the third screening frame 8.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
