Description

Technical Field

[0001] The invention relates to the technical field of pulverizing equipment, in particular to high-precision aluminum powder pulverizing equipment. Background Art

[0002] Aluminum powder is a silvery-white metallic pigment that is light in weight, has high floating power, strong hiding power, and good light and heat reflection properties. Aluminum powder crushing equipment is used to process aluminum powder into the required particle size and shape.

[0003] Chinese patent CN118253387A discloses a high-efficiency crushing equipment and crushing method for construction aluminum powder processing, which relates to the field of crushing equipment. The present invention provides a high-efficiency crushing equipment for construction aluminum powder processing capable of screening large fragments, comprising a crusher body, the crusher body is slidably connected to a filter screen, and also comprises a fixing member, the fixing member is fixed to the crusher body, a bidirectional screw is rotatably connected to the fixing member, the bidirectional screw is threadedly connected to a first extrusion member, the first extrusion member is slidably connected to the crusher body, the bidirectional screw is threadedly connected to a second extrusion member, and the second extrusion member is slidably connected to the crusher body. The invention preliminarily crushes the aluminum material through the first extrusion member and the second extrusion member, so that the aluminum material can be crushed more fully, and the number of large aluminum fragments generated can be reduced. The aluminum fragments are screened through the filter screen, and large aluminum fragments can be automatically screened out, replacing additional screening, so that it is more convenient to use.

[0004] As shown in the above patent, in order to ensure the crushing accuracy, the existing aluminum powder processing crushing equipment needs to screen the aluminum powder through a filter screen, so that the aluminum materials that meet the standard particle size pass through the filter screen for discharge, while the aluminum materials with larger particles remain on the filter screen. The commonly used aluminum powder screening methods include inclined and horizontally arranged filter screens. However, both methods have certain limitations. For the inclined filter screen, when the crushing speed is high, the accumulation of aluminum powder on the filter screen may cause the aluminum powder that meets the particle size standard to roll out together with the large-particle aluminum material, thereby affecting the screening accuracy. This phenomenon is mainly due to the rapid accumulation of aluminum powder changing the effective filtering area on the surface of the filter screen, so that some aluminum powders with qualified particle sizes cannot be fully screened. On the other hand, although the horizontally arranged filter screen can avoid the above problems to a certain extent, due to the fixed discharge position of the crushing mechanism, the aluminum materials are mainly concentrated on the filter screen surface below the discharge position, while the filtration efficiency at other positions is relatively low. This uneven distribution not only reduces the overall screening efficiency, but also may cause the filter screen in some areas to be blocked prematurely, requiring frequent cleaning.

[0005] Therefore, it is necessary to provide a high-precision aluminum powder crushing equipment to solve the above technical problems. Summary of the invention

During the rotation process, only one driving plate 19 contacts the adjusting plate 16, so that the adjusting disk 15 drives the filter assembly to swing back and forth through the connecting shaft 14, so that the aluminum material dropped on the filter assembly is evenly distributed on the filter assembly for filtering, thereby improving the filtration efficiency and preventing the filter assembly from being blocked prematurely.

Through the special structure of the arc-shaped baffle 4, the tapered portion 502 and the arc portion 501, the aluminum material in the crushing space can slide smoothly onto the filter assembly, and the different directions of downward sliding make the landing points of the aluminum material different, thereby improving the uniformity of the distribution of the aluminum material falling on the filter assembly.

The arc-shaped slide groove 701 is connected to the arc-shaped insertion groove 702, and the groove width of the arc-shaped slide groove 701 is greater than the groove width of the arc-shaped insertion groove 702. The axis line of the arc line where the arc-shaped slide groove 701 and the arc-shaped insertion groove 702 are located coincides with the axis line of the connecting shaft 14. A sliding column 25 is fixedly installed on one side of the sealing door 23, and a sliding plate 24 is fixedly installed on the end of the sliding column 25 away from the sealing door 23.

[0038] At the same time, when the first rotating shaft 2 rotates, it can drive the driving wheel 21 to rotate. When the driving wheel 21 rotates, it drives the driven wheel 20 to rotate through the transmission belt 22, thereby driving the second rotating shaft 17 to rotate. The rotation of the second rotating shaft 17 is driven by the first rotating shaft 2, so that the two driving disks 18 can rotate synchronously in the opposite direction. When the driving disk 18 rotates, it drives the driving plate 19 to rotate. After the driving plate 19 rotates to contact with the adjusting plate 16, it drives the adjusting plate 16 to rotate, thereby driving the adjusting disk 15 to rotate until the driving plate 19 is separated from the adjusting plate 16, so that the connecting shaft 14 drives the filter assembly to rotate. The two driving disks 18 rotate in the opposite direction, and during the rotation process, only one driving plate 19 contacts with the adjusting plate 16, so that the adjusting disk 15 drives the filter assembly to swing back and forth through the connecting shaft 14, so that the aluminum material dropped on the filter assembly is evenly distributed on the filter assembly for filtration, and the filtered aluminum material is discharged through the discharge hopper 102.
