The system comprises several first gears 17, each with a vertical shaft 18 movably connected to the center of its side wall. The vertical shafts 18 are inserted into the inner cavity of the vertical tube 2, and each vertical shaft 18 has a spiral blade 19 fixedly connected to its side wall. A second motor 20 is fixedly installed on the top surface of the feed shell 1, and a round shaft 21 is fixedly connected to the output end of the second motor 20. A second gear 22 is fixedly connected to the round shaft 21, and the second gear 22 meshes with the ring gear 16. A collection shell 4 is installed on the lower side of each vertical tube 2. In the technical scheme of the embodiment, the raw materials of the nafamostat dispersible tablets are added into the feeding shell 1 through the feeding pipe 38. Due to the conical bottom surface of the feeding shell 1, the raw materials of the nafamostat dispersible tablets can enter into each vertical pipe 2. The second motor 20 is started to drive the second gear 22 to rotate through the circular shaft 21. The second gear 22 meshes with the ring gear 16 to rotate. The ring gear 16 meshes with the first gear 17 to rotate. The first gear 17 drives the vertical shaft 18 to rotate. The vertical shaft 18 drives the spiral blade 19 to rotate. The raw materials in the vertical pipe 2 are quantitatively added into the inner cavity of the material collecting shell 4. The multi-station raw material adding operation can be realized. The raw material adding amount is good in controllability. The production quality and efficiency are improved. The lower side of the plurality of material collecting shells 4 is movably connected with the same circular shell 5. The side wall of the material collecting shell 4 is fixedly connected with the fixed plate 6. The movable rod 7 is movably connected with the fixed plate 6. The end of the movable rod 7 close to the circular shell 5 is fixedly connected with the pressing plate 8. The first spring 9 is sleeved on the movable rod 7. The two ends of the first spring 9 are fixedly connected with the outer wall of the movable rod 7 and the fixed plate 6, respectively. The outer side wall of the circular shell 5 is provided with the controllable adjusting assembly 10. The controllable adjusting assembly 10 comprises the annular plate 23. The annular plate 23 is arranged on the lower side of the circular shell 5. The top surface of the annular plate 23 is fixedly connected with the electric push rod 24. The other end of the electric push rod 24 is fixedly connected with the circular shell 5. The top surface of the annular plate 23 is movably connected with the plurality of connecting plates 26. The other side of each connecting plate 26 is movably connected with the movable plate 27. The movable plate 27 is fixedly connected with the two circular rods 28. The side wall of each circular rod 28 is movably connected with the side plate 29. The other end of each circular rod 28 is fixedly connected with the first push plate 25. The side plate 29 is fixedly connected with the circular shell 5. In the technical scheme of the embodiment, during use, the device is first adjusted according to the specifications of the nafamostat dispersible tablets. The electric push rod 24 is started to drive the annular plate 23 to move. The annular plate 23 drives the movable plate 27 to move through the connecting plate 26. The movable plate 27 drives the first push plate 25 to move through the circular rod 28. The first push plate 25 extends into the circular shell 5 to an appropriate length. When the material collecting shell 4 rotates, the movable rod 7 contacts the first push plate 25 at this time. The movable rod 7 is pushed by the first push plate 25 and the first spring 9 is compressed. The movable rod 7 drives the pressing plate 8 to insert into the inner cavity of the material collecting shell 4. The pressing plate 8 compresses the raw materials in the inner cavity of the material collecting shell 4.

The convenient tabletting operation of the nafamostat dispersible tablets can be completed. After tabletting is completed, the pressing plate 8 can move out of the inner cavity of the material collecting shell 4 under the elastic force of the first spring 9. The tabletting preparation operation is facilitated. Further, the inner wall of the circular shell 5 is fixedly connected with an annular slide rail 36, and the outer wall of each aggregate shell 4 is fixedly connected with a sliding block 37, which is movably connected with the annular slide rail 36, so that the aggregate shell 4 can stably rotate, and the production is facilitated.

A second spring 32 is sleeved on the outer side wall of the cross rod 30, and the two ends of the second spring 32 are fixedly connected with the outer wall of the cross rod 30 and the aggregate shell 4, respectively. An annular shell 33 is fixedly connected at the center of the circular shell 5, and a plurality of second push plates 34 are fixedly connected on the outer side wall of the annular shell 33. A through slot 39 is formed in the bottom surface of the circular shell 5 at the position of the aggregate shell 4. In the technical scheme of the embodiment, when the tabletting operation is completed, the second push plate 34 can push the cross rod 30 and the second spring 32 can be compressed under the continuous rotation of the aggregate shell 4. The cross rod 30 drives the top plate 31 to move in the inner cavity of the aggregate shell 4, and the top plate 31 pushes out the nafamostat dispersible tablets completed in the inner cavity of the aggregate shell 4. The pushed-out nafamostat dispersible tablets are discharged through the through slot 39, and the process of tabletting preparation of nafamostat dispersible tablets is completed, and the preparation efficiency is high. Further, the number of the first push plates 25, the second push plates 34 and the aggregate shells 4 is the same, and the side walls of the first push plates 25 and the second push plates 34 are arc-shaped. A roller 35 is fixedly connected to the end of the movable rod 7 away from the pressing plate 8, and another roller 35 is fixedly connected to the end of the cross rod 30 away from the top plate 31, so as to facilitate the pushing of the movable rod 7 by the first push plate 25, thereby completing the tabletting operation, and the pushing of the cross rod 30 by the second push plate 34, thereby completing the discharging operation. Further, the bottom surface of the circular shell 5 is provided with a rotary driving assembly 12, which comprises a first motor 13 fixedly installed at the center of the bottom surface of the circular shell 5.
