The output end of the first motor 5 passes through the cover body 4 and is provided with a transmission shaft 6. The transmission shaft 6 extends into the interior of the material guiding box 2 and is provided with a spiral conveying blade 7. Feeding devices are arranged on both sides of the upper end face of the cover body 4. The feeding device includes a feeding pipe 8. The lower end of the feeding pipe 8 is communicated with the housing 1.

[0029] In this embodiment, a control box 9 is fixedly arranged on the upper end face of the feeding pipe 8. A feeding hopper 10 is fixedly arranged on the upper end face of the control box 9. A rotating shaft 11 is rotatably arranged inside the control box 9. Guide plates 12 are fixedly arranged on the outer wall of the rotating shaft 11 and inside the control box 9. There are multiple guide plates 12 and they are arranged in a circular shape. A second motor 13 is arranged on the outer wall of the control box 9. The output end of the second motor 13 is fixedly connected to the rotating shaft 11.

[0030] More specifically, the user can control the first motor 5 to drive the transmission shaft 6 to drive the spiral conveying blade 7 to rotate, so as to suck the soft magnetic powder at the bottom of the housing 1 into the material guiding box 2 and gradually drop it through the heating plate 3 on the circulation channel. Through this step of circulation, the soft magnetic powder is conveyed to heat and dry it, increasing the drying effect. When feeding, the soft magnetic powder can be added into the control box 9 through the feeding hopper 10, and then control the second motor 13 to drive the rotating shaft 11 and the guide plate 12 to rotate, so that the soft magnetic powder slowly enters the housing 1 through the feeding pipe 8, thereby preventing accumulation and affecting the subsequent drying process.

Then the soft magnetic powder will fall to the bottom of the housing 1 through the heating plate 3. At this time, control the first motor 5 to make the transmission shaft 6 drive the spiral conveying blade 7 to rotate, so as to suck the soft magnetic powder at the bottom of the housing 1 into the guide box 2 and fall again through the heating plate 3 on the circulation channel. Through this step, the soft magnetic powder is circulated and conveyed to heat and dry it, and the drying effect is better. Later, the user can disassemble it by rotating the fastening nut 19 to take out the threaded column 16 from the inside of the avoidance hole 18, so as to facilitate the disassembly of the cover body 4 and the housing 1 to clean the inside of the housing 1 and the spiral conveying blade 7.

[0036] When drying, the first motor 5 can be controlled to make the transmission shaft 6 drive the spiral conveying blade 7 to rotate, so as to suck the soft magnetic powder at the bottom of the housing 1 into the guide box 2 and fall through the heating plate 3 on the circulation channel. Through this step, the soft magnetic powder is circulated and conveyed to heat and dry it, and the drying effect is better.

[0037] When feeding, the user can add the soft magnetic powder into the control box 9 through the feeding funnel 10, and then control the second motor 13 to drive the rotating shaft 11 and the feeding plate 12 to rotate, so that the soft magnetic powder slowly enters the housing 1 through the feeding pipe 8 to prevent accumulation.

[0038] After the drying is completed, the user can disassemble it by rotating the fastening nut 19 to take out the threaded column 16 from the inside of the avoidance hole 18, so as to facilitate the disassembly of the cover body 4 and the housing 1 to clean the inside of the housing 1 and the spiral conveying blade 7.
