[0002] Magnetic powder is a hard magnetic single-domain particle. It is the core component of magnetic coatings and mainly determines the magnetic properties of magnetic recording media. Magnetic powder plays an important role in industrial applications. Its main components are iron and cobalt, so a special crushing device is required to perform primary crushing of the raw materials when producing magnetic powder.
[0003] Existing magnetic powder crushing devices still have some problems in use. First, the magnetic powder crushing device requires a screening process when crushing the raw material to prevent insufficient crushing. However, most existing screens are directly fixed and require a long time to crush the remaining material through the crushing wheel. Not only is the material processing still insufficient, but the power consumption is also high. Second, a lot of dust is easily generated during the crushing process. Existing methods mainly involve adding a sealing cover or a special fume extraction mechanism for dust removal, which is inconvenient to operate and has high operating costs, thus reducing the effectiveness of use.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0033] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.
[0034] The following describes, with reference to the accompanying drawings, some embodiments of a low-loss magnetic powder pulverizing device provided by this utility model.
[0035] Example 1:
[0036] Combination Figures 1-5 As shown, this utility model provides a low-loss magnetic powder pulverizing device.
[0037] Specifically, the system includes a body 1, a drive mechanism 6, and two sets of meshing crushing rollers 9. Two sets of screen plates 10 are symmetrically arranged at the bottom of the two sets of crushing rollers 9 on the inner side of the body 1. Sealing connecting spring gaskets 15 are connected to the outer surfaces of the two sets of screen plates 10 and the raised edges of the two sets of crushing rollers 9. A partition mounting plate 12 is installed on the inner bottom of the body 1. The partition mounting plate 12 mainly facilitates the installation and assembly of the mounting sleeve 20 and its components. The mounting sleeve 20 is installed at the top center of the partition mounting plate 12, and the mounting sleeve 20 is installed at the middle of its inner bottom. A spring 18 is provided, and a movable push-pull locking post 19 connected to one side bottom end of two sets of screen plates 10 is slidably sleeved on the top outer side of the mounting sleeve 20. Two sets of elastic pads 14 are symmetrically embedded on the left and right sides of the machine body 1, near the other side of the two sets of screen plates 10. The elastic pads 14 and the sealing connection elastic pads 15 provide elastic protection, not only achieving a sealing and protective effect but also facilitating the elastic movement of the screen plates 10. Two sets of mounting rods 16 are symmetrically installed on the front and rear end faces of the machine body 1 at the bottom end of the other side of the two sets of screen plates 10. The top of the machine body 1 extends through... A feeding funnel 2 is installed through the screen. The sealing connecting spring gasket 15 connected to the raised edge of the two sets of crushing rollers 9 can be close to the top of the two sets of screen plates 10. The inner middle extension end face of the movable push-pull locking post 19 is in contact with the top face of the spring 18. The two sets of screen plates 10 are elastically connected at one end face close to each other by the sealing connecting spring gasket 15. The bottom extension end of the other side of the two sets of screen plates 10 is rotatably sleeved on the outside of the two sets of mounting rods 16. The sealing connecting spring gasket 15 connected to the other side of the two sets of screen plates 10 is elastically embedded and locked with the two sets of elastic locking gaskets 14. With the use of the above-mentioned components, the two sets of crushing rollers 9 rotate and mesh with each other to crush the material. The sealing connecting spring pads 15 at the outer protruding edges are pressed and adhered to the surface of the screen plate 10. Through the elastic action of the spring 18 installed in the mounting sleeve 20 and the rotational connection between the two sets of mounting rods 16 and one end of the two sets of screen plates 10, the movable push-pull clamp 19 drives the one end of the two sets of screen plates 10 to bounce up and down, continuously throwing the material upward, making the material crushed more thoroughly, improving the screening effect and crushing efficiency, and reducing losses.
[0038] Example 2:
[0039] Combination Figure 2 , Figure 3 and Figure 5 As shown, based on Example 1,
[0040] Specifically, the middle rear ends of the two sets of crushing rollers 9 are connected to drive shafts 17 on the outer side of the machine body 1. The output end of the drive mechanism 6 is connected to the rear end of the drive shaft 17 on the left side of the machine body 1. A mounting guide box 4 is installed at the top left side of the machine body 1. A connecting rod 24 is installed on the middle left end face of the mounting guide box 4. A dust guide pipe 5 is installed at the bottom end of the mounting guide box 4. A second conical tooth 22 is sleeved on the outer side of the connecting rod 24. A first conical tooth 21 is meshed and connected to the rear side of the second conical tooth 22. Dust guide holes 11 are opened through the connection points of the mounting guide box 4 with the machine body 1 and the dust guide pipe 5. A dust extraction fan 23 is connected to one end of the connecting rod 24 near the dust guide hole 11. The rear end of the first conical tooth 21 is located on the outside of the mounting guide box 4 and is connected to the driven shaft 8. A transmission belt 7 is connected between the driven shaft 8 and the outside of the transmission shaft 17. The bottom side extension of the dust guide pipe 5 extends through the left side of the body 1. With the use of the above components and the components in Embodiment 1, the transmission shaft 17 rotates while also driving the transmission belt 7, and the driven shaft 8 rotates to drive the first conical tooth 21 to rotate, and meshes with the second conical tooth 22 to make the connecting rod 24 drive the dust extraction fan 23 to rotate, so that the magnetic powder dust generated at the top of the body 1 is drawn into the dust guide pipe 5 through the dust guide hole 11 and reintroduced into the body 1 to prevent waste, improve the dust removal effect and reduce operating costs.
[0041] Combination Figure 1 and Figure 2 As shown, in the above embodiments,
[0042] Specifically, two sets of material guiding holes 13 are symmetrically opened on both sides of the partition mounting plate 12. The material guiding holes 13 are mainly used to guide the processed magnetic powder and some magnetic powder dust drawn into the interior of the pull-out storage box 3. The pull-out storage box 3 is slidably embedded in the bottom of the inner bottom of the machine body 1 at the bottom of the partition mounting plate 12. The pull-out storage box 3 collects magnetic powder and is also easy to pull out to remove the magnetic powder from the outside.
[0043] The working principle and usage process of this utility model are as follows: First, during use, magnetic powder raw material is placed into the inner top of the machine body 1 through the feeding funnel 2. By controlling the operation of the drive mechanism 6, the transmission shaft 17 is driven to rotate the two sets of crushing rollers 9, which interlock and crush the material. The sealing connecting spring pads 15 at the raised edges of the crushing rollers 9 are pressed and adhered to the surface of the screen plate 10. Through the elastic action of the spring 18 installed in the mounting sleeve 20 and the rotational connection between the two sets of mounting rods 16 and one end of the two sets of screen plates 10, the movable push-pull clamp 19 causes the connecting end of the two sets of screen plates 10 to bounce up and down, continuously throwing the material upward, making the material crushed more thoroughly and improving the screening effect. The crushing efficiency is improved and the overall power consumption is reduced. Secondly, when the above-mentioned components are in operation, especially the operation of the drive mechanism 6, the crushing roller 9 rotates to crush the material. At the same time, the rotation of the transmission shaft 17 also drives the transmission belt 7 to rotate the driven shaft 8, and causes the first conical tooth 21 inside the mounting guide box 4 to rotate and mesh with the second conical tooth 22, so that the connecting rod 24 drives the dust extraction fan 23 to rotate. The magnetic powder dust generated at the top of the machine body 1 is drawn into the dust guide pipe 5 through the dust guide hole 11, and then reintroduced into the bottom of the screen plate 10 inside the machine body 1 through the material guide hole 13 opened on the partition mounting plate 12 and discharged into the pull-out storage box 3. This not only improves the dust removal effect, but also reduces the operating cost and improves the overall use effect.
