Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-4 A rare earth NdFeB permanent magnet system spare mixing processing device includes a support frame 1, a mixing barrel 2 is arranged on the support frame 1, a feed hopper 22 is arranged on the top of the mixing barrel 2, and a plurality of discharge ports 23 are arranged at the bottom of the mixing barrel 2, and a sealing plate 24 is sealed and clamped in each discharge port 23.

[0026] The rare earth NdFeB permanent magnet system standby mixing processing device also includes a driving component 1 and a driving component 2. The driving component 1 is used to drive the material in the mixing barrel 2 to be stirred, and the driving component 2 is used to drive the mixing barrel 2 to rotate.

[0027] Specifically, the driving component 1 includes a driving motor 44, a driving gear 45 and multiple driven gears 46. The driving motor 44 is arranged on the top of the support seat 43. The output shaft of the driving motor 44 is axially fixedly connected to the support shaft 4. The top ends of the multiple rotating shafts 41 are fixedly sleeved with driven gears 46. The support shaft 4 is located above the support frame 1 and is fixedly sleeved with a driving gear 45. The multiple driven gears 46 are all meshed with the driving gear 45. When the driving motor 44 is started, it can drive the support shaft 4 and the multiple rotating shafts 41 to rotate, and at the same time can control the support shaft 4 and the rotating shaft 41 to keep rotating in the opposite direction. The rotating shaft 41 and the support shaft 4 are fixedly sleeved with spiral blades 1 42 arranged in the same direction. The spiral blades 1 42 stir the materials in the mixing barrel 2 in different directions as the support shaft 4 and the rotating shaft 41 rotate, thereby achieving efficient mixing of the materials in a shorter time.

[0028] Driving component 2 includes a servo motor 3, a driving gear 31 and a toothed disc 32. The toothed disc 32 is fixedly mounted on the outer wall of the mixing barrel 2, and the servo motor 3 is fixedly mounted on the support frame 1. The output shaft of the servo motor 3 is fixedly sleeved with a driving gear 31 meshing with the toothed disc 32. When the servo motor 3 is started, it can drive the mixing barrel 2 to rotate, thereby further improving the material mixing effect.

[0029] In this embodiment, a spiral blade 2 5 is fixedly installed on the inner wall of the mixing barrel 2. The spiral blade 2 5 can stir the material in the mixing barrel 2 upward or downward as the mixing barrel 2 rotates. At the same time, when the device is placed horizontally, the spiral blade 2 5 can also achieve a material conveying effect.

[0030] In this embodiment, the feed port of the feed hopper 22 extends to the top of the support frame 1 and is inclined in a direction away from the drive motor 44. This design enables the feed hopper 22 to better adapt to the feeding needs when placed vertically or horizontally.

[0031] In this embodiment, an arc plate 25 is fixed on the side of the sealing plate 24 away from the support shaft 4, the arc plate 25 abuts against the outer wall of the mixing barrel 2, and a handle is fixedly installed on the side of the arc plate 25 away from the sealing plate 24, so as to facilitate the operator to disassemble and assemble the sealing plate 24.

[0032] In this embodiment, a limit block 26 is fixedly installed on one side of the arc plate 25 close to the sealing plate 24, and the limit block 26 is clamped and installed on the outer wall of the mixing barrel 2, which can prevent the sealing plate 24 from slipping out of the discharge port 23 when the device is used in a horizontal position.

[0033] A plurality of legs for providing support for the support frame 1 are fixedly installed on the left side and the bottom side of the support frame 1, so as to facilitate adjusting the mixing barrel 2 to a vertical placement state or a horizontal placement state according to the actual use scenario requirements.

[0034] Working principle: When in use, first turn on the power supply and add the materials required for the preparation of rare earth neodymium iron boron permanent magnets into the mixing barrel 2 through the feed hopper 22, and then start the drive motor 44 and the servo motor 3. The drive motor 44 drives the support shaft 4 to rotate and controls the multiple rotating shafts 41 to rotate in the opposite direction of the support shaft 4 with the cooperation of the driving gear 45 and multiple driven gears 46, so that the spiral blade 42 can be controlled to efficiently stir the material. At the same time, the servo motor 3 drives the mixing barrel 2 to rotate, so that the material can be stirred upward or downward with the cooperation of the spiral blade 25, and the efficient mixing of the material can be achieved with the cooperation of the spiral blade 42 on the rotating shaft 41. When the mixing is completed, turn off the drive motor 44 and the servo motor 3, and then pull the sealing plate 24 through the handle to open the discharge port 23, so that the mixed material can be discharged through the discharge port 23.

[0035] The design of the device takes into account both vertical and horizontal usage scenarios, making it more applicable and able to meet the needs of different production scenarios. At the same time, it can meet the requirements of efficient, uniform and rapid material mixing in the preparation process of rare earth NdFeB permanent magnets, providing strong support for corporate production.
