[0027] Please see the appendix Figures 1 to 6 As shown, this utility model provides a grinding and processing device for manufacturing ultrafine talc powder, including a grinding box 10. A feed hopper 11 is provided at the upper end of the grinding box 10. A guide plate 12 is fixed inside the grinding box 10. A first load-bearing plate 13 is fixed to one end of the outer side of the grinding box 10. A first motor 14 is fixed to the upper end of the first load-bearing plate 13. The output end of the first motor 14 extends into the interior of the grinding box 10. A grinding roller 15 is fixed inside the grinding box 10 at the output end of the first motor 14, located above the guide plate 12. A first support plate 16 is fixed to one side inside the grinding box 10. A second support plate 17 is fixed to the side of the grinding box 10 away from the first support plate 16, and the second support plate 17 is located below the first support plate 16. At the end, a filter plate 18 is provided between the first support plate 16 and the second support plate 17. Both sides of the grinding box 10 near the first load-bearing plate 13 are fixed with outer shells 19. Sliding rods 20 are slidably connected inside the two outer shells 19. The end of the sliding rod 20 away from the outer shell 19 extends into the interior of the grinding box 10. A clamping plate 21 is fixed at one end of the sliding rod 20 and inside the grinding box 10. A baffle 22 is fixed on the outside of the sliding rod 20 and inside the outer shell 19. A spring 23 is provided inside the outer shell 19 and at the end of the baffle 22 away from the clamping plate 21. A square groove 24 is opened at the end of the grinding box 10 away from the outer shell 19. A fixing plate 25 is fixed inside the square groove 24. A limit plate 26 is slidably connected inside the fixing plate 25.

[0028] In this embodiment, the material is fed into the grinding box 10 via the feed hopper 11 at the top and evenly dispersed to the grinding roller 15 by the guide plate 12. The first motor 14 on the first load-bearing plate 13 drives the grinding roller 15 to rotate, fully grinding and crushing the talc powder raw material. The ground material falls onto the filter plate 18, which is supported and fixed by the first support plate 16 and the second support plate 17. The ultrafine talc powder that meets the particle size requirements passes through the filter plate 18 and enters the collection hopper 27. When it is necessary to replace the filter plate 18 with a different pore size, the limiting plate 26 is moved upward. At this time, under the action of the spring 23, the baffle 22 is pushed towards one end of the filter plate 18. Because the baffle 22 is fixed on the outside of the sliding rod 20, the sliding... A locking plate 21 is fixed to the end of rod 20 away from baffle 22. When spring 23 pushes baffle 22 towards one end of filter plate 18, sliding rod 20 and locking plate 21 can move towards filter plate 18. Because the two locking plates 21 are engaged with filter plate 18, when the two locking plates 21 move, they can push filter plate 18 towards the outside of grinding box 10. At this time, filter plate 18 can be pulled out, making it easy to replace filter plates 18 with different pore sizes. When filter plate 18 needs to be installed, filter plate 18 is positioned above the first support plate 16 and the second support plate 17 through square groove 24, and is engaged by the two locking plates 21. At this time, the limiting plate 26 moves downward to limit the filter plate 18. It should be noted that the two outer shells 19 have different heights, and the two locking plates 21 have slots inside, which are inclined downward to facilitate engaging filter plate 18.

[0029] Secondly, please refer to it again. Figure 3 A hopper 27 is provided inside the grinding box 10 and at the lower end of the filter plate 18, and a first handle 28 is provided at one end of the hopper 27.

[0030] In this embodiment, the qualified ultrafine talc powder screened by the filter plate 18 falls directly into the collection hopper 27 below for centralized collection. When the collection hopper 27 is full of material, the operator can hold the first handle 28 and easily pull the collection hopper 27 out of the grinding box 10.

[0031] Secondly, please refer to the following as well. Figure 1 and Figure 3 A sliding plate 29 is slidably connected inside the grinding box 10 and above the first support plate 16. Multiple magnet blocks 30 are evenly arranged inside the upper part of the sliding plate 29 and inside the grinding box 10. A second handle 31 is fixed on the side of the sliding plate 29 away from the magnet blocks 30.

[0032] In this embodiment, during the grinding process, the operator can flexibly push or pull the sliding plate 29 to slide on the upper end of the first support plate 16 by holding the second handle 31. Multiple magnet blocks 30 evenly distributed inside the sliding plate 29 can effectively adsorb magnetic impurities such as iron filings generated during the grinding process due to mechanical friction or component wear, preventing these impurities from mixing into the finished talc powder. When the magnet blocks 30 are full of impurities, the operator can pull the sliding plate 29 out of the grinding chamber 10 to easily clean the impurities on the magnet blocks 30. It should be noted that the talc powder falls onto the inclined surface at the upper end of the sliding plate 29 after passing through the guide plate 12, and then falls onto the filter plate 18 for sieving.

[0033] To further understand and explain, Figure 3 For example, a second load-bearing plate 32 is fixed at one end of the grinding box 10 near the outer shell 19, and a second motor 33 is fixed at the upper end of the second load-bearing plate 32. A discharge hole 34 is opened on one side of the grinding box 10 near the second support plate 17. A rotating rod 35 is rotatably connected inside the discharge hole 34, and the output end of the second motor 33 is fixedly connected to the rotating rod 35. A feeding plate 36 is fixed on the outside of the rotating rod 35 and inside the discharge hole 34.

[0034] In this embodiment, the second motor 33 is started, and the output end of the second motor 33 drives the rotating rod 35 to rotate. The rotating rod 35 rotates within the discharge hole 34, and the material-pushing plate 36 on the outside of the rotating rod 35 rotates synchronously. When the ultrafine talc powder that has been ground and screened in the grinding box 10 is discharged through the discharge hole 34, the material-pushing plate 36 continuously rotates to promptly push and move the talc powder accumulated near the discharge hole 34, preventing material from clogging the discharge hole 34 and ensuring that the talc powder can be discharged evenly and continuously.

[0035] In a preferred embodiment, please refer to Figures 1 to 3 The grinding box 10 has a discharge port 40 and a feed port 41 fixed from top to bottom on the side near the second support plate 17. A housing 42 is fixed between the discharge port 40 and the feed port 41. A third motor 43 is mounted on the upper end of the housing 42. A rotating shaft 44 is fixed at the output end of the third motor 43. The lower end of the rotating shaft 44 extends into the interior of the housing 42. A spiral blade 45 is fixed on the outer side of the rotating shaft 44.

[0036] In this embodiment, after the third motor 43 starts, it drives the rotating shaft 44 to rotate, causing the outer spiral blades 45 to rotate synchronously inside the housing 42. The ultrafine talc powder that has passed the grinding in the grinding box 10 will directly pass through the filter plate 18 and enter the collection hopper 27. Unqualified talc powder will be conveyed through the feed inlet 41 to the inside of the housing 42 via the feeding plate 36. The spiral blades 45, through the pushing force generated by their rotation, will convey the talc powder along the inside of the housing 42 to the upper part of the grinding box 10 for secondary grinding, thereby improving the grinding quality of the talc powder and facilitating the promotion of the equipment. It should be noted that the discharge port 40 and the feed inlet 41 are all connected to the grinding box 10.

[0037] Secondly, please refer to it again. Figure 3 Figure 4 A first positioning plate 46 is fixed on the inner wall of the grinding box 10 and between the two clamping plates 21, and a second positioning plate 47 is fixed on the inner wall of the grinding box 10 on the side of the two clamping plates 21 that are far apart from each other.

[0038] In this embodiment, the first positioning plate 46 and the second positioning plate 47 cooperate with the clamping plate 21 to form a stable limit on the filter plate 18, preventing displacement due to material impact.

[0039] The working principle of this utility is as follows:

[0040] During operation, the material is fed into the feed hopper 11 at the top of the grinding chamber 10, dispersed to the grinding roller 15 by the guide plate 12, and driven to rotate by the first motor 14 on the first support plate 13 for grinding and crushing. The ground material falls onto the filter plate 18 supported by the first support plate 16 and the second support plate 17. Qualified ultrafine talc powder passes through the filter plate 18 and enters the collection hopper 27 for collection, while unqualified coarse particles are intercepted and fed into the housing 42 through the feed inlet 41 via the feeding plate 36. The third motor 43 drives the rotating shaft 44 and the spiral blades 45 to transport it back to the top of the grinding chamber 10 for secondary grinding. The magnet 30 on the sliding plate 29 can adsorb magnetic impurities such as iron filings generated during the grinding process, ensuring product purity. When replacing filter plate 18, the limiting plate 26 is moved upwards, and the spring 23 pushes the baffle 22, sliding rod 20, and clamping plate 21 to move, pushing the filter plate 18 out. During installation, the filter plate 18 is placed on the first support plate 16 and the second support plate 17 through the square groove 24, and is engaged by the clamping plate 21 and limited by the limiting plate 26. At the same time, the first positioning plate 46, the second positioning plate 47 cooperate with the clamping plate 21 to ensure the filter plate 18 is stable. In addition, the second motor 33 drives the rotating rod 35 and the material feeding plate 36 to rotate, preventing the discharge hole 34 from being blocked and ensuring that the material is discharged evenly.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
