[0030] Example 2: Figures 1-7 As shown, the quantitative feeding component 2 includes a feeding port 201 and a rotating shaft 204, the bottom of the feeding port 201 is connected to a conveying pipe 202, a plurality of partitions 205 are distributed on the outside of the rotating shaft 204, a motor 203 is installed at one end of the rotating shaft 204, and the cleaning component 3 includes two dust hoods 304, the sides of the two dust hoods 304 are both installed with connecting blocks 303, a threaded rod 302 is passed through the interior of a single connecting block 303, and a lifting and lowering device is installed on the top of the threaded rod 302. The motor 301 and the single connecting block 303 are penetrated by a guide rod 305, the bottom of the dust cover 304 is connected to a connecting pipe, one end of the connecting pipe is installed with a dust box 306, the bottom of the dust box 306 is installed with a suction fan 307, the outer side of the suction fan 307 is installed with a protective frame 308, the inside of the dust box 306 is installed with a filter element 309, the side of the dust box 306 is symmetrically installed with a slide groove 310, and the inside of the slide groove 310 is movably installed with a sealing plate 311.

[0031] In this embodiment, the powder inlet 201 facilitates the entry of the powder into the device. The motor 203 drives the rotation of the rotating shaft 204 electrically, so that the rotating shaft 204 drives the partition plate 205 to rotate. The partition plates 205 are evenly distributed outside the rotating shaft 204, which is conducive to realizing quantitative feeding, facilitating the accurate control of the amount of powder entering the lower punch die 404, thus ensuring the quality of tablet production, avoiding situations such as excessive overflow of redundant powder due to excessive feeding, reducing the waste of powder, and saving the raw material cost. After the production is completed, the suction fan 307 operates to generate suction force on the dust suction hood 304 to suck up the powder scattered during the processing. At the same time, the lifting motor 301 drives the rotation of the threaded rod 302 electrically, and then drives the dust suction hood 304 to lift. The guide rod 305 is conducive to providing a guiding function and improving the cleaning range, so that the sucked powder raw materials are stored inside the dust suction box 306. The filter element 309 prevents the powder raw materials from entering the inside of the suction fan 307. The movable sealing plate 311 moves inside the chute 310, which is conducive to cleaning the collected powder raw materials.

[0032] The working principle of this embodiment is as follows: when in use, first, the powder enters the device through the feed port 201, and the motor 203 electrically drives the rotating shaft 204 to rotate, so that the rotating shaft 204 drives the partition 205 to rotate, and the partition 205 is evenly distributed on the outside of the rotating shaft 204, which is conducive to quantitative unloading. Then the cylinder 104 extends to push the upper punch plate 409 down, and then the hydraulic telescopic column 410 is extended to push the punch head 413 down, and the inside of the single lower punch die 404 is punched and tableted. After the punching is completed, the electric telescopic column 405 rises, pushing the pad 406 so that the tabletted tablets are separated from the inside of the lower punch die 404. At the same time, the first motor 407 electrically drives the push plate 408 to rotate, so that the push plate 408 passes above the pad 406 to push out the tabletted tablets, and finally the tablets are unloaded through the unloading plate 105, and the transmission shaft 403 is rotated by the rotating motor 402. This is conducive to driving the turntable 401 to rotate, which is conducive to continuous tableting. When the production is completed, the suction fan 307 is operated to make the dust hood 304 generate suction to absorb the scattered medicine powder during the processing. At the same time, the threaded rod 302 is electrically driven to rotate by the lifting motor 301, thereby driving the dust hood 304 to rise and fall, which is conducive to increasing the cleaning range, so that the sucked medicine powder raw materials are stored in the dust box 306, and finally the sealing plate 311 is moved to move in the slide groove 310, which is conducive to cleaning the collected medicine powder raw materials. By pulling out the limit rod 417, the limit rod 417 releases the limit on the fixed rod 416, and then the fixed rod 416 is pulled outward so that the fixed rod 416 is separated from the inside of the mounting groove 411, and then the limit plate 415 is moved so that the limit plate 415 is separated from the inside of the fixed frame 414, and finally the mounting block 412 is moved to the side, which is convenient for disassembly and replacement of the punch head 413.
