Description

Technical Field

[0001] This utility model relates to the field of crushing technology, and in particular to a device for crushing agglomerated resin grinding wheel abrasive. Background Technology

[0002] The abrasive used to make resin grinding wheels needs to be mixed before it is formed into a grinding wheel. This involves mixing white fused alumina and resin to coat the surface of the white fused alumina with a layer of resin. After mixing, the abrasive needs to be dried in an environment with specific temperature and humidity. After drying, a small amount of abrasive will clump together.

[0003] Comparing with the published patent number CN223404994U, a resin grinding wheel abrasive agglomeration crushing device is disclosed, comprising: a crushing box, the interior of which is configured as a cavity; a feed hopper, disposed on the crushing box; a drawer, disposed inside the crushing box; a working plate, disposed above the drawer; a crushing mechanism, disposed above the working plate; and a spreading mechanism, disposed between the working plate and the drawer; wherein, the spreading mechanism comprises: a collection box, disposed below the working plate, and the bottom plate of the collection box has multiple drainage holes; and a spreading pipe, inclined downwardly connecting to both sides of the collection box, and the other side of the spreading pipe extending to the side wall of the drawer, and the spreading pipe having a vertically penetrating distributing port.

[0004] Although the above solution solves the problem that the material will concentrate in the middle of the collection box after crushing and cannot fall evenly into the collection box, the above solution still has problems such as poor crushing effect and low crushing efficiency when crushing agglomerated materials, because some agglomerated materials are large in size and number. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a resin grinding wheel abrasive agglomeration crushing device, comprising a crushing barrel, a collecting basket provided on the inner side of the crushing barrel, a guide cylinder welded to the surface of the crushing barrel, a motor body fixedly mounted on the surface of the crushing barrel, a stirring shaft fixedly mounted on the output end of the motor body, a first crushing blade, a second crushing blade and a third crushing blade welded to the surface of the stirring shaft, a first filter screen, a second filter screen and a third filter screen welded to the inner side of the crushing barrel, a collecting cover plate welded to the inner side of the crushing barrel, and a distributing guide pipe welded to the surface of the collecting cover plate.

[0007] Preferably, the first, second, and third filter screens are evenly distributed from top to bottom inside the crushing hopper, and the material collection cover is funnel-shaped.

[0008] Preferably, the first crushing blade is located above the first filter screen, the second crushing blade is located on the opposite side of the first and second filter screens, and the third crushing blade is located below the second filter screen.

[0009] Preferably, the surface of the material distribution conduit is provided with a discharge groove, and the material distribution conduit is bifurcated in four directions.

[0010] Preferably, a material discharge support rod is welded and installed on the surface of the stirring shaft, and the material discharge support rod is located inside the material distribution guide.

[0011] Preferably, a reinforcing base is welded and installed on the lower side of the crushing hopper, an external groove is opened on the surface of the crushing hopper, the collecting basket is slidably installed on the inner wall of the external groove on the crushing hopper, and an auxiliary handle is welded and installed on the surface of the collecting basket.

[0012] Preferably, the surface of the crushing hopper is provided with an auxiliary groove, and a positioning plate is slidably installed on the inner wall of the auxiliary groove on the crushing hopper, with the surface of the positioning plate abutting and sliding on the surface of the collecting basket.

[0013] Preferably, the collecting basket is located below the distributing conduit, and the collecting cover is located below the third filter screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) In this resin grinding wheel abrasive agglomeration crushing device, the resin grinding wheel agglomerate that passes through the second filter screen to the third filter screen is crushed by the third crushing blade. The resin grinding wheel agglomerate that does not pass through the first, second and third filter screens will continue to be crushed until the crushed resin grinding wheel agglomerate passes through the third filter screen to the collection hood for collection. It is also discharged into the collection bin in five directions with the distribution guide. This method not only ensures the convenience of multi-stage synchronous crushing of agglomerated resin grinding wheel agglomerate, but also improves the disadvantage of poor crushing efficiency caused by material congestion when using single crushing of traditional resin grinding wheel agglomerate. Thus, this device ensures that resin grinding wheel agglomerate has multiple effects such as multi-stage synchronous crushing, graded filtration crushing, and five-directional material distribution and discharge. This improves the ease of high-efficiency crushing and uniform material distribution and discharge of the device, and greatly improves the operating efficiency of resin grinding wheel agglomerate processing.

[0015] (2) In this resin abrasive agglomeration crushing device, small pieces of resin abrasive that fall from the first filter screen to the second filter screen will be crushed by the second crushing blade. The resin abrasive that passes through the second filter screen to the third filter screen will be crushed more finely by the third crushing blade. In this way, the resin abrasive can form a predetermined material and be crushed in a multi-stage manner, thereby greatly improving the efficiency of agglomeration resin abrasive crushing.

[0016] (3) The resin grinding wheel abrasive agglomeration crushing device can discharge the collected resin grinding wheel agglomerate in multiple directions through the four-way branching of the material distribution guide. In addition, it can achieve five-way synchronous material discharge by cooperating with the material discharge groove on the material distribution guide. The material discharge groove, in cooperation with the material discharge support rod, ensures that the resin grinding wheel agglomerate at the material distribution guide has a dynamic driving effect. In this way, the uniformity of material collection at the collection bin is ensured. Attached Figure Description

[0023] Please see Figure 1-4 This utility model provides a technical solution: a resin grinding wheel abrasive agglomeration crushing device, including a crushing barrel 1, a reinforcing base 2 welded to the lower side of the crushing barrel 1, an external groove 3 on the surface of the crushing barrel 1, and a collecting basket 4 slidably installed on the inner wall of the external groove 3 on the crushing barrel 1. The function of the collecting basket 4 is to collect the crushed resin grinding wheel abrasive inside the crushing barrel 1.

[0024] Furthermore, an auxiliary handle 5 is welded and installed on the surface of the material collection basket 4. The function of the auxiliary handle 5 is to assist the material collection basket 4 in being pulled outward or assembled at the crushing bucket 1.

[0025] Furthermore, a guide cylinder 6 is welded and installed on the surface of the crushing barrel 1. The function of the guide cylinder 6 is to guide the resin grinding wheel abrasive that needs to be processed.

[0026] Furthermore, an auxiliary groove 7 is provided on the surface of the crushing bucket 1. A positioning plate 8 is slidably installed on the inner wall of the auxiliary groove 7 on the crushing bucket 1. The surface of the positioning plate 8 slides against the surface of the collecting basket 4. The function of the positioning plate 8 is to limit the collecting basket 4 after it aligns with the external groove 3 on the crushing bucket 1, so as to achieve the stability of the collecting basket 4 inside the crushing bucket 1. When the collecting basket 4 is separated from the crushing bucket 1, the positioning plate 8 only needs to slide up at the auxiliary groove 7 without obstructing the collecting basket 4.

[0027] Furthermore, a motor body 9 is fixedly installed on the surface of the crushing barrel 1, and a stirring shaft 10 is fixedly installed at the output end of the motor body 9. A first crushing blade 11, a second crushing blade 12, and a third crushing blade 13 are welded and installed on the surface of the stirring shaft 10. The stirring shaft 10 is rotated by the operation of the motor body 9, and the stirring shaft 10 will simultaneously drive the first crushing blade 11, the second crushing blade 12, and the third crushing blade 13 to crush the resin grinding wheel abrasive inside the crushing barrel 1. The motor body 9 is existing publicly disclosed technology, and the related power structure is also existing publicly disclosed technology.

[0028] Furthermore, a first filter screen 14, a second filter screen 15, and a third filter screen 16 are welded and installed on the inner side of the crushing barrel 1. The first filter screen 14, the second filter screen 15, and the third filter screen 16 are evenly distributed from top to bottom on the inner side of the crushing barrel 1. The first crushing blade 11 is located above the first filter screen 14, the second crushing blade 12 is located on the opposite side of the first filter screen 14 and the second filter screen 15, and the third crushing blade 13 is located below the second filter screen 15. The first crushing blade 11, the second crushing blade 12, and the third crushing blade 13 are driven by the motor body 9 to crush the agglomerated resin grinding wheel abrasive. During crushing, the first crusher 11 crushes large pieces of resin abrasive into powder or small pieces at the first filter screen 14. The small pieces of resin abrasive that fall through the first filter screen 14 to the second filter screen 15 are crushed by the second crusher 12. The resin abrasive that passes through the second filter screen 15 and reaches the third filter screen 16 is then crushed more finely by the third crusher 13. In this way, the resin abrasive can form a predetermined material and be crushed in a multi-stage manner, which greatly improves the efficiency of crushing agglomerated resin abrasive.

[0029] Furthermore, a collecting cover plate 17 is welded and installed on the inner side of the crushing barrel 1. The collecting cover plate 17 is located below the third filter screen 16. The collecting cover plate 17 is funnel-shaped. The function of the collecting cover plate 17 is to centrally discharge the crushed resin grinding wheel abrasive.

[0030] Furthermore, a material distribution guide 18 is welded and installed on the surface of the material collection cover plate 17.

The four-way bifurcation of the material distribution guide 18 allows for multi-directional discharge of the collected resin grinding wheel abrasive. In conjunction with the discharge groove 19 on the material distribution guide 18, five-way synchronous discharge can be achieved. The discharge groove 19, in conjunction with the material discharge support rod 20, ensures that the resin grinding wheel abrasive at the material distribution guide 18 has a dynamic pushing effect. In this way, the uniformity of material collection at the material collection basket 4 is ensured.

[0031] Working principle: A resin grinding wheel abrasive agglomeration crushing device. After the agglomerated resin grinding wheel agglomerates are guided at the guide cylinder 6, the motor body 9 drives the first crushing blade 11, the second crushing blade 12, and the third crushing blade 13 to rotate. At this time, the resin grinding wheel agglomerates that reach the second filter screen 15 are crushed. The resin grinding wheel agglomerates that can pass through the first filter screen 14 will fall to the second filter screen 15 and be crushed by the second crushing blade 12. The resin grinding wheel agglomerates that pass through the second filter screen 15 and reach the third filter screen 16 are crushed by the third crushing blade 13. The resin grinding wheel agglomerates that do not pass through the first filter screen 14, the second filter screen 15, and the third filter screen 16 will continue to be crushed until the crushed resin grinding wheel agglomerates pass through the third filter screen 16 and reach the collection cover plate 17 for collection.
