Then, turn on the first cylinder 13. The output end of the first cylinder 13 drives the first pressing block 14 to move upward, and the tablets can be pushed up. Then, turn on the first servo motor 6. The output end of the first servo motor 6 rotates to drive the worm 9 to rotate, thereby driving the worm gear 38 and the second rotating rod 39 to rotate, and then driving the first turntable 10 and the second turntable 15 to rotate. Under the action of the baffle 29, the tablets can be discharged from the storage channel 27. A collection container can be placed below the storage channel 27 to collect the tablets. After collecting the tablets, keep the second turntable 15 rotating, and turn on the air pump 23. The residual medicinal powder on the second turntable 15 can be sucked into the filter screen 36 through the third pipeline 20. To avoid blockage, turn on the third servo motor 21.
