The conveying assembly 2 includes a material adding tank 201 and a motor 217. A first vertical pipe 203 is centrally mounted on the upper end of the material adding tank 201, and a feeding pipe 202 is mounted near the edge of the upper end of the material adding tank 201. A tubular filter screen 205 is mounted on the outer side of the bottom end of the material adding tank 201, and the cleaning assembly 3 is mounted on the outer side of the tubular filter screen 205. A second vertical pipe 206 is mounted on the bottom end of the tubular filter screen 205, and a bent pipe 207 is mounted on the side wall of the second vertical pipe 206. The bottom end of the bent pipe 207 is connected to the second vertical pipe 206. A common collection pipe 208 is installed between them. A conveying pipe 209 is installed at the other end of the bend 207. A connecting rope 210 is provided on the inner side of the conveying pipe 209, the first vertical pipe 203, the tubular filter screen 205, the second vertical pipe 206 and the bend 207. Several equally spaced installation pipes 214 are installed on the outer side of the connecting rope 210. Several ring-arranged connecting rods 213 are installed on the outer side of the installation pipes 214. An installation ring 211 is installed at the end of the connecting rod 213. A filter screen 215 is installed at the upper end of the installation ring 211. A motor 217 is installed between the conveying pipe 209 and the first vertical pipe 203 through the mounting frame 1. A gear 218 is installed at the output end of the motor 217.

[0022] Motor 217 drives gear 218 to rotate, gear 218 drives mounting ring 211 and its connected components to move downward. Mounting ring 211 drives connecting rope 210 to move through connecting rod 213 and mounting tube 214, thereby driving multiple mounting rings 211 and their connected components to move synchronously. Tablets are added into material addition tank 201 through feeding tube 202. The tablets are received by filter screen 215 at the outlet of material addition tank 201 and then enter tubular filter screen 205 to be cleaned by cleaning component 3. The cleaned tablets fall as they pass through second vertical tube 206, bend tube 207 and collection tube 208 and are collected by container.

[0023] like Figure 3As shown, the bottom end of the first vertical pipe 203 extends into the material adding tank 201. A flow regulating block 204 is installed on the lower part of the outer side of the first vertical pipe 203. The flow regulating block 204 is designed in the shape of a frustum. By setting the flow regulating block 204, the amount of tablets entering the tubular filter screen 205 can be controlled.

[0024] like Figure 4 As shown, an annular rubber block 212 is installed on the outer side of the mounting ring 211. The annular rubber block 212 is hollow. A frustum-shaped position correction block 216 is installed at the bottom of the mounting ring 211. Several through holes are opened on the side wall of the position correction block 216. The frustum-shaped position correction block 216 facilitates the mounting ring 211 to enter the first vertical tube 203. The annular rubber block 212 can fill the gap between the mounting ring 211 and the tubular filter screen 205 to prevent the pills from falling out.

[0025] like Figure 1 As shown, the upper part of the conveying pipe 209 and the lower part of the bend 207 are both arc-shaped. The arc design facilitates the connection rope 210 to drive the installation ring 211, the annular rubber block 212, the connecting rod 213, the installation pipe 214, the filter screen 215 and the position correction block 216 through.

[0026] like Figure 5 As shown, the cleaning component 3 includes a hollow housing 301. A pipe 303 is installed on one side of the housing 301, and a blower 302 is installed on the other side of the housing 301. The blower 302 generates a high-speed airflow to blow off the powder on the tablet. The blown-off powder is mixed with the air and discharged through the pipe 303, and collected through a container.
