[0013] A method for using a traditional Chinese medicine raw material grinding device includes the following steps: S1: The Chinese medicine is first put into the inclined surface of the top of the grinding block through the feeding pipe on the top cover. The inclined surface of the top of the grinding block forms a grinding structure. The electric cylinder pushes the top column and the grinding block to move upward through the extrusion cylinder and the extrusion spring. At this time, the grinding block will press the Chinese medicine raw material into the inner wall of the upper inclined grinding ring and the lower inclined grinding ring to form another grinding structure. The second motor drives the inner rotating cylinder and the insertion rod to rotate through the connecting toothed ring. The insertion rod will drive the grinding block to rotate synchronously. S2: The upper gear on the first motor rotates counterclockwise, and the upper gear drives the outer ring frame to rotate clockwise through the outer gear ring. At this time, the limit rod on the outer ring frame can drive the control plate and the upper inclined grinding ring to rotate clockwise synchronously through the limit groove. The upper inclined grinding ring will drive the lower inclined grinding ring at the bottom to rotate clockwise, while the grinding block rotates counterclockwise, thus starting the first-stage grinding of Chinese medicine. S3: Then the first motor rotates clockwise. At this time, the limiting rod on the outer ring frame will enter the side with the wider limiting groove, so that the limiting rod no longer positions the upper inclined grinding ring. This allows the upper inclined grinding ring to move up and down along the vertical rod while rotating itself. The upper inclined grinding ring rotates counterclockwise, and at the same time, the electric cylinder will continue to push the grinding block upward, so that the top inclined surface of the grinding block and the inner inclined surface of the lower inclined grinding ring are in contact, thereby accelerating the entry of the Chinese medicine raw materials between the upper and lower inclined grinding rings. Meanwhile, the first motor will drive the upper gear and the transmission rod to rotate, and the transmission rod will... The lifting cylinder drives the bottom one-way tooth to rotate clockwise, which in turn drives the lower gear to rotate. The lower gear drives the lower inclined grinding ring to rotate clockwise through the internal gear ring and the connecting ring. The upper and lower inclined grinding rings rotate in opposite directions. The inclined teeth at the bottom of the upper inclined grinding ring will move up and down along the inclined teeth at the top of the lower inclined grinding ring. The upper and lower inclined grinding rings will continuously split and move. The continuous and staggered movement of the inclined teeth on the upper and lower inclined grinding rings can effectively cut through the fiber structure of Chinese medicine, thereby improving the grinding efficiency and realizing the secondary fiber cutting and grinding of Chinese medicine. S4: The Chinese medicine powder is discharged into the discharge port at the bottom of the shell through the outer edges of the upper and lower inclined grinding rings.

The primary grinding of Chinese herbal medicine raw materials is achieved by the rotation of the grinding block 27.

[0022] A method for using a traditional Chinese medicine raw material grinding device includes the following steps: S1: The Chinese medicine is first put into the inclined surface of the top of the grinding block 27 through the feeding pipe on the upper cover 1. The inclined surface of the top of the grinding block 27 forms a grinding structure. The electric cylinder 23 pushes the top column 25 and the grinding block 27 upward through the extrusion cylinder 24 and the extrusion spring 26. At this time, the grinding block 27 will press the Chinese medicine raw material into the inner wall of the upper inclined grinding ring 7 and the lower inclined grinding ring 17 to form another grinding structure. The second motor 22 drives the inner rotating cylinder 20 and the insertion rod 28 to rotate through the connecting toothed ring 21. The insertion rod 28 will drive the grinding block 27 to rotate synchronously. S2: The upper gear 12 on the first motor 13 rotates counterclockwise. The upper gear 12 drives the outer ring frame 10 to rotate clockwise through the outer gear ring 11. At this time, the limit rod 9 on the outer ring frame 10 can drive the control disk 3 and the upper inclined grinding ring 7 to rotate clockwise synchronously through the limiting groove 8. The upper inclined grinding ring 7 will drive the lower inclined grinding ring 17 at the bottom to rotate clockwise, while the grinding block 27 rotates counterclockwise, thus starting the first-stage grinding of Chinese medicine. S3: Then, the first motor 13 rotates clockwise. At this time, the limiting rod 9 on the outer ring frame 10 will enter the side with the larger width of the limiting groove 8, so that the limiting rod 9 no longer positions the upper inclined grinding ring 7. This allows the upper inclined grinding ring 7 to move up and down along the vertical rod 5 while rotating itself. The upper inclined grinding ring 7 rotates counterclockwise, and at the same time, the electric cylinder 23 will continue to push the grinding block 27 upward, so that the top inclined surface of the grinding block 27 and the inner inclined surface of the lower inclined grinding ring 17 fit together, thereby accelerating the entry of the Chinese medicine raw materials between the upper inclined grinding ring 7 and the lower inclined grinding ring 17. Meanwhile, the first motor 13 will drive the upper gear 12 and the transmission rod 1401 to rotate, and the transmission rod 1401 will pass through The lifting cylinder 1402 drives the bottom one-way tooth 1405 to rotate clockwise, which in turn drives the lower gear 1406 to rotate. The lower gear 1406 drives the lower inclined grinding ring 17 to rotate clockwise through the internal gear ring 15 and the connecting ring 16. The upper inclined grinding ring 7 and the lower inclined grinding ring 17 rotate in opposite directions. The inclined teeth at the bottom of the upper inclined grinding ring 7 will move up and down along the inclined teeth at the top of the lower inclined grinding ring 17. The upper inclined grinding ring 7 and the lower inclined grinding ring 17 will continuously split and move. The continuous and interlaced movement of the inclined teeth on the upper inclined grinding ring 7 and the lower inclined grinding ring 17 can effectively cut through the fiber structure of Chinese medicine, thereby improving the grinding efficiency and realizing the secondary fiber cutting and grinding of Chinese medicine. S4: The Chinese medicine powder is discharged into the discharge port at the bottom of the shell 2 through the outer edges of the upper inclined grinding ring 7 and the lower inclined grinding ring 17.
