[0002] Permanent magnet materials are widely used in many fields such as modern industry, electronic equipment and new energy, and the performance of the permanent magnet materials is largely dependent on the mixing quality of the magnetic powder. In the production process of the permanent magnet material, the stirring mechanism of the magnetic powder mixer is a key component for ensuring uniform mixing of the magnetic powder. However, the conventional stirring mechanism usually adopts a simple paddle stirrer. During stirring, the magnetic powder is prone to accumulate around the container wall and the stirrer, resulting in uneven mixing, and the magnetic powder in some areas cannot be fully contacted and mixed, which affects the consistency and performance stability of the permanent magnet material.

A fixed connection is provided on the side wall of the driving mixing roller 19. Multiple active stirring rods 21 are connected to the drive stirring roller 20, and multiple driven stirring rods 22 are fixedly connected to the side wall of the driven stirring roller 20. A bracket 6 is fixedly connected to the upper surface of the sealing cover 5, and a drive motor 7 is fixedly installed on the top side inside the bracket 6. The output end of the drive motor 7 is fixedly connected to the top end of the active stirring roller 19. The active stirring roller 19 is connected to the driven stirring roller 20 through a drive assembly. The drive assembly includes an active gear 8 and two driven gears 9. The active gear 8 is sleeved on the side wall of the top end of the active stirring roller 19, and the driven gears that mesh with the active gear 8 are sleeved on the side wall of the top end of the driven stirring roller 20. 9. A feed pipe 23 is fixedly connected to the upper surface of the sealing cover 5, and a discharge pipe 15 is fixedly connected to the lower surface of the conical mixing tank 3. The conical mixing tank 3 is connected to the sealing cover 5 through multiple sets of fixing components. The fixing components include fixing bolts 16, which are threaded on the side wall of the conical mixing tank 3 and used to fix the sealing cover 5 inside the conical mixing tank 3. A drive mechanism for driving the right connecting shaft 4 to rotate is provided on the right support plate 2. The drive mechanism includes an electric telescopic rod 13, a toothed plate 12, and a full gear 10. A mounting plate 11 is fixedly connected to one side of the right support plate 2. An electric telescopic rod 13 is fixedly installed on the upper surface of the container. A toothed plate 12 is fixedly connected to the output end of the electric telescopic rod 13. One end of the right connecting shaft 4 passes through the side wall of the right support plate 2 and is fixedly connected to a full gear 10 that meshes with the toothed plate 12. A controller 14 is fixedly installed on one side of the right support plate 2. The drive motor 7 and the electric telescopic rod 13 are both electrically connected to the controller 14. A fixing plate 17 is fixedly connected to the inner side wall of the conical mixing tank 3. Multiple limiting holes 18 are opened on the upper surface of the fixing plate 17. The bottom ends of the active stirring roller 19 and the driven stirring roller 20 can both extend into the limiting holes 18.

[0019] The implementation principle of the mixing mechanism of a permanent magnet material powder mixer according to an embodiment of this application is as follows: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. The permanent magnet material powder to be mixed is poured into the conical mixing tank 3 through the feed pipe 23. The drive motor 7 is started, and its operation drives the active stirring roller 19 to rotate. The active stirring rod 21 on the side wall of the active stirring roller 19 rotates accordingly, stirring the magnetic powder. When the active stirring roller 19 rotates, the active gear 8 drives the driven gear 9, thereby causing the driven stirring roller 20 to rotate synchronously. The driven stirring rod 22 on the driven stirring roller 20 also begins to stir the magnetic powder. The active stirring rod 21 and the driven stirring rod 22 cooperate with each other to stir the magnetic powder from different angles, ensuring the magnetic powder is fully agitated within the conical mixing tank 3, promoting mixing. During the stirring process, if it is necessary to adjust the angle of the conical mixing tank 3 to optimize the stirring effect, the drive mechanism can be started through the controller 14. When the electric telescopic rod 13 extends or retracts, it drives the toothed plate 12 to move. The toothed plate 12 interacts with the full gear 10, causing the connecting shaft 4 to rotate. This, in turn, causes the conical mixing tank 3 to rotate around the connecting shaft 4 by a certain angle, changing the distribution of magnetic powder in the mixing tank and improving the mixing uniformity. The fixed plate 17 fixed on the inner wall of the conical mixing tank 3 has a limiting hole 18. The bottom ends of the active stirring roller 19 and the driven stirring roller 20 can extend into the limiting hole 18. The limiting hole 18 limits and supports the stirring roller, ensuring the stability of the stirring roller during rotation and preventing the stirring roller from shaking and affecting the mixing effect. After mixing is completed, the discharge pipe 15 is opened, and the mixed magnetic powder can be discharged. Since the conical mixing tank 3 is connected to the sealing cover 5 through the fixed component, the fixing bolt 16 of the fixed component is threaded on the side wall of the conical mixing tank 3. Loosening the fixing bolt 16 can easily remove the sealing cover 5, which is convenient for cleaning and maintenance of the inside of the conical mixing tank 3. During this process, the active stirring roller 19 and the driven stirring roller 20 work together, while the active stirring rod 21 and the driven stirring rod 22 stir the magnetic powder from different directions, allowing the magnetic powder to be fully agitated within the conical mixing tank 3. This effectively prevents the magnetic powder from accumulating on the container walls and around the stirrer, improving the mixing uniformity of the magnetic powder and thus enhancing the consistency and performance stability of the permanent magnet material. The angle of the conical mixing tank 3 can be adjusted via the electric telescopic rod 13. During the stirring process, the distribution of the magnetic powder within the mixing tank can be flexibly changed according to the characteristics and mixing conditions of the magnetic powder, optimizing the stirring effect.
