[0022] Please see Figure 1-4 A rotary tablet press includes a tablet press body 1, a support plate 2, and a pressing component 3. The support plate 2 is disposed inside the tablet press body 1 and can rotate outside the tablet press body 1. When the support plate 2 rotates, it can drive the anti-hazing tablet to move. A transmission mechanism is provided inside the tablet press body 1, and a scraper mechanism is provided outside the support plate 2.

[0023] Specifically, the transmission mechanism includes a fixed plate 111, a drive motor 112, a reducer 113, a connecting rod 114, a gear 115, a connecting ring 116, and a fixed ring 117. The fixed plate 111 is welded to the inner side of the tablet press body 1. The drive motor 112 is installed at the bottom of a set of fixed plates 111. The reducer 113 is installed at the top of the fixed plate 111. One end of the connecting rod 114 is fixedly connected to the output end of the drive motor 112. The rod of the drive motor 112 is connected to the input end of the reducer 113. The other end of the connecting rod 114 is rotatably connected to the inner top wall of the tablet press body 1.
