[0002] A rotary tablet press is a machine that uses a pressing wheel to press granular materials into tablets, with multiple punches and dies evenly distributed on a turntable moving up and down in a circular motion along a certain trajectory. The rotary tablet press is mainly composed of an upper punch, a middle die and a lower punch. Compared with a single-punch tablet press, a rotary tablet press can not only continuously press granular materials, but also press various shapes of special-shaped tablets. Therefore, it is widely used in the pharmaceutical field.

However, during the tableting process, part of the granular raw material may adhere to the lower punches 10 or the upper punches 11, thereby causing the loss of the raw material, and therefore it is not convenient to use;

[0005] 2. A Chinese medicinal material rotary tablet press forming device disclosed in the above document, when in use, the above document mentions that the outer side walls of multiple groups of upper punches 11 are slidably connected with multiple groups of guide holes on the upper die 9, multiple groups of lower punches 10 are respectively slidably connected with multiple groups of guide holes on the bottom die 7, multiple groups of first springs 12 are connected to the bottom end of the upper die 9, and multiple groups of first springs 12 are connected to the top end of the middle die 8. The upper punch 11 is subjected to external force by the pressing wheel 15, so that the upper punch 11 tablets the medicinal material. After the pressing is completed, the upper punch 11 returns to the initial position under the action of the first spring 12. Since the first spring 12 is connected to the middle die 8, it is not convenient for the staff to load and unload the upper punch 11, and it is not convenient to replace the upper punch 11, so it is not convenient to use;

[0060] Specifically, during use, when the cleaning brush 45 and the first fixed plate 44 are moving, the first fixed plate 44 drives the slide plate 48 to move synchronously. Friction is generated between the slide plate 48 and the slide rod 46 due to the relative movement, and the friction hinders the relative movement between the slide rod 46 and the slide plate 48, thereby making the movement of the first fixed plate 44 and the cleaning brush 45 more stable.

At the same time, the medicinal raw materials in the feeding box 61 enter the discharge pipe 67 through the connecting pipe 66, and are transported to the middle mold 24 through the discharge pipe 67. The connecting pipe 66 is made of a hose.

[0063] Based on the above-mentioned rotary tablet press used for medicinal material processing, when in use, first turn the knob 71, the knob 71 drives the second inner rod 73 to move through the second set rod 72, and drives the pressing wheel 76 to move through the second inner rod 73 and the third mounting plate 74. When the pressing wheel 76 moves to the specified position, then add medicinal raw materials to the feeding box 61, and start the first servo motor 21.
