[0030] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0031] Please refer to the drawings, which is a schematic structural diagram of a preferred embodiment of a magnetic powder fine powder vibration sieving device and a magnetic fine powder production line provided by the present utility model.

[0032] A magnetic powder fine powder vibration sieving device includes:

[0033] A box body 1 is provided with a feed inlet 2 and a discharge outlet 3. A vibration sieve mechanism 4 is arranged inside the box body 1. The vibration sieve mechanism 4 includes an arc sieve 5 and a vibration component. The arc sieve 5 is arranged below the feed inlet 2 and is connected to the vibration component. The vibration component is used to drive the arc sieve 5 to perform vibration sieving.

[0034] A mesh plate assembly includes a plurality of mesh plates 13. The plurality of mesh plates 13 are arranged on one side of the feed inlet 2 and are arranged above the arc sieve 5 in a row. The top end of the mesh plate 13 is connected to the box body 1.

[0035] The magnetic powder fine powder vibration sieving device of the present utility model drives the arc sieve 5 to perform vibration sieving through the vibration component, and utilizes the arc surface structure of the arc sieve 5 to improve the screening and discharging rate of the material. At the same time, a mesh plate assembly is arranged above the arc sieve 5. There is a distance between the bottom of each mesh plate 13 of the mesh plate assembly and the surface of the arc sieve 5. When the arc sieve 5 vibrates, the material on the surface is shaken off. At this time, the mesh plate 13 can be used to disperse the shaken-off material. At the same time, the plurality of mesh plates 13 are arranged at intervals above the arc sieve 5. When there is more material in the arc sieve 5, it can play a role in separating the material and prevent the material on the arc sieve 5 from piling up and affecting the discharging speed of the material.

[0036] Preferably, please refer to Figure 2 、 3 As shown, the feed inlet 2 is located at the top wall of the first end of the box body 1 along the length direction, the discharge outlet 3 is located at the bottom of the side wall of the second end of the box body 1 along the length direction, the first end of the arc sieve 5 in the circumferential direction is located below the feed inlet 2, and the second end of the arc sieve 5 in the circumferential direction is arranged close to the discharge outlet 3.

[0037] It can be understood that the feed inlet 2 can realize the feeding of the material to the first end of the arc sieve 5. Since the upper surface of the arc sieve 5 is an arc surface structure, the material at the first end of the arc sieve 5 can be more easily shaken off and splashed towards the center position of the arc sieve 5 when the arc sieve 5 vibrates. At this time, the mesh plate 13 on the arc sieve 5 plays a role in dispersing the material, which can effectively reduce the phenomenon of material caking, ensure that the caked material is broken up and screened out faster, and at the same time, the mesh plate 13 can also prevent the material from splashing too high and falling out of the arc sieve 5.

[0038] Preferably, please refer toFigure 2 , 3 As shown in FIGS. 3 and 4, the vibration assembly includes a vibration motor 8 and a support plate 9. The support plate 9 is connected to the output shaft of the vibration motor 8. The support plate 9 is inclined downward in the direction towards the discharge port 3. The support plate 9 is used to support the arc-shaped sieve 5, and the vibration motor 8 is used to drive the support plate 9 and the arc-shaped sieve 5 to vibrate.

[0039] It can be understood that the materials in the arc-shaped sieve 5 fall onto the support plate 9 through the screening action of the arc-shaped sieve 5. The inclined support plate 9 vibrates synchronously with the arc-shaped sieve 5, which can also realize the rapid feeding of the materials from the first end of the support plate 9 to the discharge port 3. At the same time, when the materials at various parts of the arc-shaped sieve 5 are fed synchronously, it is not easy to accumulate on the inclined support plate 9, which is beneficial to the continuous screening and discharging of the materials in the arc-shaped sieve 5.

[0040] It should be noted that an installation groove 7 is provided below the bottom plate 10 of the box body 1. The installation groove 7 is used to install and limit the vibration motor 8, and at the same time, it can play a role in shielding and protecting the vibration motor 8.

[0041] Preferably, as shown in FIGS. Figure 2 , 3 3 and 4, both opposite sides of the arc-shaped sieve 5 are connected to the support plate 9 through compression springs 12. The compression springs 12 are used to elastically support the arc-shaped sieve 5 above the support plate 9.

[0042] It can be understood that the compression springs 12 can realize the elastic connection between the support plate 9 and the arc-shaped sieve 5, effectively reducing the excessive impact on the arc-shaped sieve 5 caused by the vibration of the support plate 9, realizing the buffer protection of both the support plate 9 and the arc-shaped sieve 5, and being beneficial to improving the service life of the arc-shaped sieve 5.

[0043] Preferably, as shown in FIGS. Figure 2 , 3 3 and 4, a limiting roller 6 is provided below the arc-shaped sieve 5. Both ends of the limiting roller 6 are connected to the side wall of the box body 1. The limiting roller 6 is used to support the bottom of the arc-shaped sieve 5.

[0044] It can be understood that the limiting roller 6 can play an auxiliary supporting role for the bottom of the arc-shaped sieve 5, and at the same time, it can also play a limiting role for the bottom of the arc-shaped sieve 5. In addition, the limiting roller 6 and the compression springs 12 cooperate to enable the arc-shaped sieve 5 to swing around the limiting roller 6, and the compression springs 12 play a limiting and buffering role for both ends of the arc-shaped sieve 5, effectively ensuring the stable operation of the arc-shaped sieve 5.

[0045] Preferably, as shown in FIG. Figure 3 3, two limiting plates 14 are provided on the upper surface of the arc-shaped sieve 5. The two limiting plates 14 are respectively arranged at opposite ends in the axial direction of the arc-shaped sieve 5. The vertical projection of the mesh plate 13 on the arc-shaped sieve 5 is located between the two limiting plates 14.

[0046] It can be understood that the limiting plate 14 can limit the materials on the upper surface of the arc sieve 5, preventing the materials from being splashed out of the arc sieve 5 due to vibration. At the same time, the mesh plate 13 is located between the limiting plates 14 on both sides, which can avoid interference between the mesh plate 13 and the limiting plates 14 and prevent interference with the movement of the arc sieve 5.

[0047] Preferably, the top of the mesh plate 13 is connected to the box body 1 through a limiting spring, and the mesh plate 13 is used to elastically move relative to the box body 1 through the limiting spring under the impact of the materials.

[0048] It can be understood that the limiting spring can play a buffering and protective role for the mesh plate 13, preventing the vibrating screen 5 from colliding and damaging the mesh plate 13 when the vibration amplitude is too large, which is beneficial to improving the service life of the mesh plate 13.

[0049] Preferably, as shown in Figure 2 the distances from the bottoms of the multiple mesh plates 13 to the surface of the arc sieve 5 are the same.

[0050] It can be understood that there is a spacing between the mesh plate 13 and the arc sieve 5, which ensures that the arc sieve 5 avoids frequent collisions with the mesh plate 13 during general arc vibration, preventing damage to the mesh plate 13 and the arc sieve 5, and is beneficial to improving the service life of the components.

[0051] Preferably, as shown in Figure 1 a guide frame is provided at the feed inlet 2, and the guide frame is used to guide the materials to one side of the arc sieve 5. A blanking plate 11 is provided at the discharge outlet 3, and the upper surface of the blanking plate 11 is an inclined structure.

[0052] It can be understood that the guide frame can smoothly guide the materials above the arc sieve 5, reducing the phenomenon that the materials directly fall from a high place into the arc sieve 5 and are shaken off by the arc sieve 5. The blanking plate 11 can play an auxiliary discharging role, enabling the screened materials to be discharged more smoothly from the discharge outlet 3 and improving the production efficiency.

[0053] According to another aspect of the present invention, a magnetic fine powder production line is further provided, which includes the above-mentioned magnetic powder fine powder vibrating sieving device.

[0054] The magnetic fine powder production line of the present invention also has the above-mentioned beneficial effects. It includes reducing the phenomenon that materials are likely to accumulate on the sieve mesh, resulting in unsmooth discharge of the sieve mesh, and improving the production efficiency.

The description of the above examples is only used to help understand the method and its core idea of the present utility model. The above is only the preferred implementation manner of the present utility model. It should be noted that due to the limitation of literal expression and objectively there are infinite specific structures, for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements, refinements or changes can be made, or the above technical features can be combined in an appropriate manner; these improvements, refinements, changes or combinations, or directly applying the concept and technical solution of the utility model to other occasions without improvement, should all be regarded as the protection scope of the present utility model.
