Technical Field

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are permanent magnet materials with super strong magnetism. Neodymium magnets have a wide range of applications in modern industry and technology. In electronic devices such as mobile phones, computers, and speakers, they can provide a strong magnetic field to achieve miniaturized and high-performance electromagnetic conversion functions. In the production process of neodymium magnets, the particle size of the raw materials has a great influence on the performance of the final product.

[0005] Therefore, there is an urgent need for a raw material crushing device for neodymium magnet production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a raw material crushing device for neodymium magnet production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] like Figure 1-8 As shown, the raw material crushing device for neodymium magnet production proposed in this embodiment includes a support base 1, an mounting plate B8 fixedly connected to the outer wall of the support base 1, and a rotating seat 2 fixedly connected to the top wall of the support base 1. It also includes:

[0032] The tilting filter assembly includes a guide ring 19 rotatably connected to the inner wall of the rotating seat 2. A crushing box 5 is fixedly connected to the outer wall of the guide ring 19. Symmetrically distributed hoppers 11 are fixedly connected to the outer wall of the crushing box 5. Symmetrically distributed filter plates 12 are rotatably connected to the inner wall of the hoppers 11. Uniformly distributed telescopic rods 20 are rotatably connected to the outer wall of the filter plates 12, and the end of the telescopic rods 20 away from the filter plates 12 is rotatably connected to the hoppers 11. A strong spring 21 is sleeved on the outer wall of the telescopic rods 20, and the strong spring 21 is fixedly connected to the filter plates 12. The end of the strong spring 21 away from the filter plates 12 is fixedly connected to the hoppers 11. If the crushed raw material meets the specified size standard, it will pass through the filter plates 12 and fall into the inclined plate 4 in the collection bin 3, and slide out through the inclined plate 4. Raw materials that do not meet the standard will remain on the filter plates 12. At this time, the drive motor B9 is started, and the output of the drive motor B9 is activated. The drive plate 17 rotates, which in turn drives the crushing box 5 to rotate 180°, thus flipping the position of the hopper 11. When the hopper 11 is facing upwards, because the raw material is large and its weight is greater than the elastic force of the strong spring 21, the raw material will press the filter plate 12 to rotate inside the hopper 11, thus discharging the material. At this time, the hopper 11 is the feeding hopper. When the hopper 11 is facing downwards, the filter plate 12 cannot rotate because it is limited by the hopper 11 and the limiting plate 13. This allows the raw material that does not meet the standard to be retained, thus filtering the raw material. At this time, the hopper 11 is the discharging hopper. After the crushing box 5 rotates, the retained raw material falls back onto the crushing blade 23. At this time, the output end of the drive motor A7 reverses, that is, the crushing blade 23 reverses, thus realizing secondary crushing of the raw material. The crushing box 5 can be flipped multiple times as needed to crush the raw material.

[0033] Limiting plate 13 is fixedly connected to the inner wall of hopper 11.

[0034] The drive component is fixedly connected to the outer wall of the support base 1.

[0035] like Figure 5As shown, in a preferred embodiment, based on the above method, the drive assembly further includes a mounting plate B8 fixedly connected to the outer wall of the support base 1, a drive motor B9 fixedly connected to the top wall of the mounting plate B8, a drive plate 17 fixedly connected to the output end of the drive motor B9, and the drive plate 17 fixedly connected to the crushing box 5. The drive plate 17 is driven to rotate by the output end of the drive motor B9, thereby driving the crushing box 5 to rotate.

[0036] like Figure 7-8 As shown, in a preferred embodiment, based on the above method, the outer wall of the crushing box 5 is further provided with symmetrically distributed rotating rollers 10, the outer wall of the rotating rollers 10 is fixedly connected with uniformly distributed crushing blades 23, and the outer wall of the rotating rollers 10 is also fixedly connected with gears 18, and the symmetrical gears 18 are meshed together. The inner wall of the crushing box 5 is fixedly connected with uniformly distributed rotor plates 22, and the rotor plates 22 and crushing blades 23 are staggered. The gears 18 mesh with the gears 18 to drive the gears 18 on the other side to rotate, thereby driving the rotating rollers 10 on the other side to rotate, and thus driving the crushing blades 23 to rotate, thereby realizing the crushing of raw materials.

[0037] like Figure 4 As shown, in a preferred embodiment, based on the above method, the top wall of the support base 1 is further fixedly connected to a collection bin 3, and the inner wall of the collection bin 3 is fixedly connected to an inclined plate 4. The crushed raw material falls into the collection bin 3 and slides out through the inclined plate 4.

[0038] like Figure 2-3 As shown, in a preferred embodiment, based on the above method, the outer wall of the support base 1 is further provided with uniformly distributed buffer columns 14 fixedly connected, the outer wall of the buffer columns 14 is slidably connected with a base box 15, the outer wall of the base box 15 is rotatably connected with symmetrically distributed dampers 16, and the top wall of the dampers 16 is rotatably connected with the support base 1.

[0039] like Figure 8 As shown, in a preferred embodiment, based on the above method, a mounting plate A6 is fixedly connected to the outer wall of the crushing box 5, a drive motor A7 is fixedly connected to the top wall of the mounting plate A6, and the output end of the drive motor A7 is fixedly connected to the rotating roller 10, and the output end of the drive motor A7 drives the rotating roller 10 to rotate.

[0040] Specifically, in use, the raw material crushing device for neodymium magnet production works as follows: the output of drive motor A7 drives the rotating roller 10 to rotate, which in turn drives the other side of gear 18 to rotate, thereby driving the other side of rotating roller 10 to rotate, which in turn drives the crushing blade 23 to rotate, thus crushing the raw material. If the crushed raw material meets the specified size standard, it will pass through the filter plate 12 and fall into the inclined plate 4 in the collection bin 3, and slide out through the inclined plate 4. Raw material that does not meet the standard will remain on the filter plate 12. At this time, drive motor B9 is started, and the output of drive motor B9 drives the drive plate 17 to rotate, which in turn drives the crushing box 5 to rotate, that is, the crushing box 5 rotates 180°, thereby flipping the position of the hopper 11. When the hopper 11 faces upward, the raw material is large and its weight exceeds the elastic force of the strong spring 21. As a result, when the raw material is put in, it will press the filter plate 12 to rotate inside the hopper 11, thus achieving material discharge. At this time, the hopper 11 is the feeding hopper. When the hopper 11 faces downward, the filter plate 12 cannot rotate due to the limiting effect of the hopper 11 and the limiting plate 13. This allows the raw material that does not meet the standard to be retained, thus achieving material filtration. At this time, the hopper 11 is the discharging hopper. When the crushing box 5 rotates, the retained raw material falls back onto the crushing blade 23. At this time, the output end of the drive motor A7 reverses, that is, the crushing blade 23 reverses, thus achieving secondary crushing of the raw material. The crushing box 5 can be flipped multiple times as needed to achieve crushing of the raw material.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
