The pipe 22 transfers the internal water to the box body 1 through the feed port 24, and is flushed through the pressure wheel 1 3, the pressure wheel 2 4, the screen 7 and the collection cover 11 respectively, and then transmitted to the motor 2 16 to raise the water through the cage 18, and then is put into the box body 1 again through the transmission port 17 to complete the circulation flushing. After flushing, start the valve 2 25 to let the water flow out through the outlet pipe 13.

[0036] Working principle: Pour the powdered medicine into the box body 1 through the feed port 24, start the motor 12 to drive the pressing wheel 13 to rotate, and at the same time, the gear 15 drives the gear 26 to mesh and rotate, so that the pressing wheel 24 rotates, and the powder is pressed into a sheet through the tablet pressing holes on the outer wall of the pressing wheel 13 and the pressing wheel 24, and then rotates and falls onto the screen tray 7 to complete the screening of the sheet medicine and some unpressed powder. The sheet medicine remains on the screen tray 7, and the powder falls into the collection cover 11, and then flows into the conveying pipe 15. When a certain amount is accumulated, the motor 2 16 is started to pass through the screw The cage 18 lifts the powder up, and then puts it into the feed port 24 through the transmission port 17 to complete the cycle tableting and avoid waste. The water pump 20 is started to extract the water source in the water tank 19, and the water is transmitted to the feed port 24 through the pipeline 22 to flow into the box body 1, and is rinsed by the pressing wheel 1 3, the pressing wheel 2 4, the screen 7 and the collecting cover 11 respectively, and then flows into the conveying pipe 15 and brings the water up through the cage 18, and then flows into the feed port 24 through the transmission port 17 to complete the cycle flushing. After flushing, open the valve 2 25 to let the water flow out through the outlet pipe 13.
