When the tablet is being pressed, the motor 401 drives the outer shell 402 and the inner frame 404 to rotate synchronously. During rotation, the powder enters the mold 403 and is leveled by the feeding component 2, and then the pressing rod 304 is pressed down by the second hydraulic rod 303. The third hydraulic rod 405 forms a support at the lower part of the mold 403. The powder is pressed into tablets between the pressing rod 304 and the third hydraulic rod 405. Then the pressing rod 304 moves up to its original position, and the tablet moves to the upper end of the mold 403 under the drive of the third hydraulic rod 405. As the outer shell 402 and the inner frame 404 rotate, it falls onto the guide plate 5.

After filling the mold 403, the first telescopic cylinder 202 drives the scraping sleeve 201, and the second telescopic cylinder 205 drives the push plate 204 to move backward simultaneously, so as to scrape the excess powder above the mold 403 backward. Repeating the above operations can complete the feeding before tablet pressing. The first hydraulic rod 301 is connected to the mounting plate 302 and the frame 1 by bolts. The second hydraulic rod 303 is connected to the mounting plate 302 by bolts. The telescopic rod of the second hydraulic rod 303 is connected to the pressing rod 304 by bolts.

The third hydraulic rod 405 forms a support at the lower part of the mold 403. The powder is pressed into tablets between the pressing rod 304 and the third hydraulic rod 405. Then, the pressing rod 304 moves up to its original position. The tablets are driven by the third hydraulic rod 405 to move to the upper end of the mold 403. As the outer shell 402 and the inner frame 404 rotate, they fall onto the guide plate 5. The guide plate 5 can be set as a hollow structure, so that the powder carried by the tablets can automatically fall into the powder collection tray 6 during the falling process. Moreover, the powder collection tray 6 can collect the powder that falls during feeding, which is convenient for the recovery of the powder and reduces losses. The tablets can fall into the tablet collection tray 7, making the collection more convenient.
