The outer surface of the ferrule 10 is rotatably connected with the connecting rod 11. One end of the telescopic rod of the second hydraulic cylinder 7 is fixedly connected with a lower forming column 12. The outer surface of the lower forming column 12 is slidably connected with the inner side wall of the forming tube 3. The upper surface of the lower forming column 12 is provided with an arc-shaped groove. The upper surface of the second hydraulic cylinder 7 is fixedly connected with a spring 13. The upper end of the spring 13 abuts against the lower surface of the ferrule 10. The powder storage box 2, the second hydraulic cylinder 7 and the sorting box 14 are all provided with a plurality of them and are evenly distributed in a rectangular array.

[0028] In order to facilitate the adjustment of the size of the pressed tablets of the medicine, as shown in the appendix Figures 1 to 6As shown in the figure, the present application adopts the following structure. Through the settings of the powder storage box 2, the forming tube 3, the first hydraulic cylinder 4, the upper forming column 6, the second hydraulic cylinder 7 and the lower forming column 12, the tablet pressing device for drug production has the effect of facilitating the adjustment of the size of the pressed tablets. During actual use, after pouring the powder into the interior of the powder storage box 2, by controlling the extension distance of the telescopic rod of the second hydraulic cylinder 7, the height of the lower forming column 12 is adjusted, thereby controlling the volume of the powder entering the interior of the forming tube 3. After the lower forming column 12 reaches the designated position, the first hydraulic cylinder 4 drives the upper forming column 6 to rise, so that the powder in the powder storage box 2 enters the interior of the forming tube 3. Then, through the extension of the telescopic rod of the first hydraulic cylinder 4, the lower pressing plate 5 is driven to move downward. Subsequently, the upper forming column 6 presses downward. A tablet mold is formed between the arc-shaped groove on the lower surface of the upper forming column 6, the arc-shaped groove on the upper surface of the lower forming column 12 and the inner side wall of the forming tube 3 to press the powder to form tablets. Then, the telescopic rod of the second hydraulic cylinder 7 retracts, and the upper forming column 6 continues to move downward. As the lower forming column 12 descends, it will abut against the upper surface of the collar 10 and press the collar 10 downward. At this time, through the connection between the connecting rod 11 and the blanking rod 8, the blanking rod 8 is driven to rotate along the hinge point with the second hydraulic cylinder 7, so that the pushing block 9 at the upper end of the blanking rod 8 moves inlayingly, pushing the tablets down and causing the tablets to fall, thus completing the pressing operation of the tablets. During this process, before the powder enters the interior of the forming tube 3, by adjusting the height of the lower forming column 12, the volume of the powder entering the interior of the forming tube 3 can be adjusted. And by adjusting the distance between the upper forming column 6 and the lower forming column 12 after pressing, the volume of the tablets after pressing can be adjusted. That is, through the coordinated settings of the powder storage box 2, the forming tube 3, the first hydraulic cylinder 4, the upper forming column 6, the second hydraulic cylinder 7 and the lower forming column 12, the distance between the lower forming column 12 and the upper forming column 6 can be adjusted during use, thereby controlling the amount of powder entering the interior of the forming tube 3, and by adjusting the distance after pressing, it is convenient to adjust the size of the tablets, thus achieving the purpose of facilitating the adjustment of the size of the pressed tablets of the drug;
