At this time, the forward and reverse motor 601 is started by the external controller. The operation of the forward and reverse motor 601 can drive the threaded rod 602 to rotate forward and reverse. At this time, the moving block 604 on the surface of the threaded rod 602 can move back and forth. Since the sliding rod 603 and the threaded rod 602 are connected by the L-shaped scraper 606, at the same time, the L-shaped scraper 606 connected to the two moving plates 605 is pushed, thereby pushing and scraping the medicine powder retained at the tableting position below the multiple extrusion columns 302. Since the discharge plate 402 is located on one side above the discharge port 102, the medicine powder can be pushed to the inside of the discharge port 102. At this time, the medicine powder enters the interior of the collecting tank 8 and can be filtered and collected through the multiple filter holes 901 opened on the surface of the filter plate 9. When the medicine is tableted, the handle 801 can be used to drive the collecting tank 8 to be drawn out. Since the medicine and part of the medicine powder are located on the surface of the filter plate 9, the collecting tank 8 can be shaken to make the medicine powder pass through the multiple filter holes 901 for filtering. The filter plate 9 can be taken out using two handles 903, so that the medicine powder located at the bottom of the inner cavity of the collecting tank 8 can be collected in a centralized manner, which is convenient for subsequent continued use. By setting up a scraping device 6, the medicine powder remaining after tableting can be scraped and collected, so that the medicine powder can be reused to avoid waste of resources.
