[0032] Reference Figure 3 and Figure 4 The material feeding and discharging mechanism includes a cover plate 210. One side of the mixing box 200 is open. The cover plate 210 is rotatably connected to the mixing box 200 in a direction of covering or moving away from the opening. The shape of the cover plate 210 completely covers the opening. The mixing box 200 is also provided with a second driving mechanism 500 for driving the cover plate 210 to rotate.
[0033] The second driving mechanism 500 includes a first gear 510, a second gear 520 and a first motor 530. The first gear 510 is rotatably connected to the mixing box 200.

When all the medicine powders in the mixing box 200 have entered the storage box 300, the mixing box 200 is driven back to the position where the cover plate 210 faces upward. The materials are discharged through the discharge port 320 on the storage box 300 to complete the next process.
[0043] The medicine powder is divided into multiple parts, each part is mixed, and then all the powders are stored together, so that the medicine powder is better mixed, uneven mixing is less likely to occur, and the quality of the medicine powder is improved.
