Detailed implementation manners
[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application belong to the scope of protection of the present application.
[0034] The abrasive member described in this embodiment, such as Figures 1 - 8 shown, includes a fixed abrasive member 10, a moving abrasive member 20, and a feed plate 30. Among them, the fixed abrasive member 10 is fixedly arranged in an external barrel in the working state, and the fixed abrasive member 10 is arranged in a cylindrical shape. A first abrasive groove 11 is arranged on the inner wall of the fixed abrasive member 10; among them, the moving abrasive member 20 is arranged corresponding to the fixed abrasive member 10. A second abrasive groove 21 is arranged on the outer wall of the moving abrasive member 20. In the working state, the moving abrasive member 20 is rotationally arranged in the cylindrical fixed abrasive member 10, and the material enters between the fixed abrasive member 10 and the moving abrasive member 20 to grind the material through the first abrasive groove 11 and the second abrasive groove 21; the feed plate 30 is arranged on one side of the moving abrasive member 20, and the side of the feed plate 30 away from the moving abrasive member 20 includes a plurality of feed blades 31; in the working state, the feed plate 30 rotates with the moving abrasive member 20 and is arranged in the fixed abrasive member 10, and the feed blade 31 and the inner wall of the fixed abrasive member form a feed channel 32.
[0035] That is to say, in the above technical solution, the fixed abrasive member 10 uses its inner wall and the first abrasive groove 11 arranged on the inner wall as the abrasive surface, and the moving abrasive member 20 uses its outer wall and the second abrasive groove 21 arranged on the outer wall as the abrasive surface. In the working state, when the moving abrasive member 20 is driven to rotate relative to the fixed abrasive member 10, the two abrasive surfaces rotate relative to each other, and the material enters between the two abrasive surfaces through the feed channel 32 for grinding or coating. The arrangement of the feed plate 30 and the feed blades 31 enables the material to enter between the two abrasive surfaces successively through the feed channel 32 to participate in abrasion, avoiding blockage of the material in the barrel.
[0036] In addition, in the above technical solution, when the two abrasive surfaces are worn to different degrees after working for a period of time and the abrasive effect is difficult to meet the requirements, the moving abrasive member 20 is pushed a certain distance towards the cylindrical inner side of the fixed abrasive member 10, so that the worn abrasive surfaces are staggered, and the unused inner wall part of the fixed abrasive member 10 and the outer wall part of the moving abrasive member 20 cooperate for abrasion, reducing the downtime and ensuring the orderly progress of the abrasive work.
[0037] It should be noted that, in the above technical solution, preferably, the first abrasive groove 11 is one of an inclined straight groove, a threaded groove, an arc groove, and a straight groove; correspondingly, the second abrasive groove 21 is also one of an inclined straight groove, a threaded groove, an arc groove, and a straight groove, and the shape of the second abrasive groove 21 is the same as the shape of the first abrasive groove 11.
[0038] A more optimal situation is that, in order to prevent the material between the first abrasive groove 11 and the second abrasive groove 21 from directly escaping along the channel formed by the first abrasive groove 11 and the second abrasive groove 21 without participating in or with little participation in abrasion, both the first abrasive groove 11 and the second abrasive groove 21 are one of an inclined straight groove, a threaded groove, and an arc groove, and the second abrasive groove 21 has the same shape as the first abrasive groove 11. In this technical solution, it is difficult to form a channel for the material to directly escape in the corresponding groove bodies of the abrasive surfaces formed by the inclined straight groove, the threaded groove, and the arc groove, and the material can only be discharged from one side of the abrasive surface after sufficient abrasion.
[0039] In another technical solution, the quantity ratio of the first abrasive groove 11 to the second abrasive groove 21 is 1:(0.7 - 1.2). In a specific solution, the width of the first abrasive groove 11 / second abrasive groove 21 is less than the spacing between two adjacent first abrasive grooves 11 / second abrasive grooves 21. The spacing between the first abrasive grooves 11 / second abrasive grooves 21 generally depends on the abrasion requirements of the material to be abraded. However, a smaller spacing often affects the feeding speed and thus the abrasion efficiency.
[0040] Preferably, the top end of the feeding knife 31 is inclined; in the working state, the top wall of the feeding knife 31 is higher as it gets closer to the inner wall of the fixed abrasive part. In this technical solution, after the material falls on the top end of the feeding disk 30, it can gather in the middle of the feeding disk 30, facilitating the material to enter the two abrasive surfaces through the feeding channel 32 on one side of the feeding knife 31 for abrasion.
[0041] It should be noted that in some technical solutions, the abrasive part further includes a chassis 40. Among them, the chassis is detachably arranged at the end of the moving abrasive part 20 away from the feeding disk 30, and a connection hole 41 connected to an external drive shaft is provided at the center of the chassis 40. During the assembly process, the external drive shaft can be directly passed through the connection hole 41 to drive the moving abrasive part 20 through the chassis 40; when the moving abrasive part 20 and / or the fixed abrasive part 10 are worn after a period of use, the feeding of the moving abrasive part 20 towards the fixed abrasive part 10 can be achieved by adjusting the position of the chassis on the corresponding drive shaft, ensuring the continuation of the abrasion process.
[0042] In a specific solution, in order to ensure the concentricity between the chassis 40 and the moving abrasive part 20, a positioning table 42 is provided on one side of the chassis 40 facing the moving abrasive part 20, and a positioning groove 22 is correspondingly provided on one side of the moving abrasive part 20. The positioning table 42 is adapted to the positioning groove 22. During the actual assembly process, the chassis 40 and the moving abrasive part 20 are detachably arranged. During the actual assembly process, considering the assembly of the feed tray 30, the moving abrasive part 20 is connected to one end of the chassis 40 by a countersunk bolt. In this process, the positioning table 42 and the positioning groove 22 are used to make the chassis 40 and the moving abrasive part 20 coaxially arranged. Of course, the positioning groove 22 can also be provided on the side of the chassis 40 facing the moving abrasive part 20. In this case, a positioning table 42 is correspondingly provided on the side of the moving abrasive part 20 facing the chassis 40. In either of the above ways, the coaxiality during the assembly of the chassis 40 and the moving abrasive part 20 can be ensured.
[0043] During the actual working process, in order to ensure the overall stability of the abrasive part to ensure the smooth progress of the abrasive process, a plurality of reinforcing ribs 43 are provided on the side of the chassis 40 away from the moving abrasive part.
[0044] Based on the foregoing explanation, the chassis 40 is detachably assembled on one side of the moving abrasive part 20. After the assembly is completed, when the moving abrasive part 20 extends into the fixed abrasive part 10 for abrasive, the outer diameter of the chassis 40 is adapted to the outer diameter of the fixed abrasive part 10 on the side facing the chassis 40; so that in the working state, a discharge channel 12 is formed by the gap between the fixed abrasive part 10 and the chassis 40.
[0045] After working for a period of time, when the fixed abrasive part 10 and / or the moving abrasive part 20 are worn, the moving abrasive part 20 moves towards the fixed abrasive part 10 again. In this process, the outer wall of the fixed abrasive part 10 never contacts the outer wall of the chassis 40, so that the discharge channel 12 can be maintained to discharge materials smoothly.
[0046] Preferably, a groove 44 is provided on the outer side of the chassis 40. The materials after the abrasives escaping from the discharge channel 12 are driven by the groove 44 and discharged from the discharge channel 12 in time. It can be understood that in order to make the groove 44 better assist in discharging, a plurality of grooves 44 are provided, and the plurality of grooves 44 are evenly distributed on the outer side of the chassis 40.
[0047] In still another technical solution, the inner wall of the fixed abrasive part 10 is provided with a conical structure. The inner diameter of the end cooperating with the moving abrasive part 20 in the working state is larger than the inner diameter of the end away from the moving abrasive part 20; the outer wall of the moving abrasive part 20 is correspondingly provided with a conical structure corresponding to the inner wall of the fixed abrasive part 10, and the taper of the outer wall of the moving abrasive part 20 is adapted to the taper of the inner wall of the fixed abrasive part 10. Correspondingly, the outer walls of the feed tray 30 and the feed knife 31 are provided with a conical structure, and the taper of the feed tray 30 and the feed knife 31 is the same as the taper of the moving abrasive part 20.
[0048] The inner wall of the fixed grinding member 10 and the outer walls of the moving grinding member 20 and the feeding knife 31 are provided with a conical structure, so that the materials under the centrifugal force can smoothly enter the grinding surface formed by the moving grinding member 20 and the fixed grinding member 10 from the feeding channel 32 during the working process. In addition, in the above solution, the structures of the feeding disk 30 and the outer wall of the moving grinding member 20 are adapted to the inner wall structure of the fixed grinding member 10. When the grinding surface is worn after working for a period of time, after the moving grinding member 20 feeds a certain distance towards the inside of the fixed grinding member 10, the new grinding surface has the same working condition as the previous grinding surface, ensuring that the materials of the same specification can be continuously ground, and the consistency of the powder quality during the whole grinding process can be maintained.
[0049] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present application.
