A plurality of punches 10 are provided on the lower end surface of the punch 9, and the plurality of punches 10 are respectively matched with the plurality of mold holes 6. A control component is provided between the base 1 and the punch 9, and the control component includes a supporting body 11 arranged on the base 1, and a support rod 12 is provided at one end of the supporting body 11 away from the base 1, and a rotating disk 13 is rotatably connected to the support rod 12. A connecting rod 14 is fixedly connected to one side wall of the punch 9, and a lifting rod 15 is rotatably connected to the connecting rod 14. The end of the lifting rod 15 away from the connecting rod 14 is rotatably connected to one side of the rotating disk 13, and a lower pressing plate 16 is fixedly connected to the other side of the rotating disk 13. A protective layer is provided on the lower end surface of the lower pressing plate 16. Through the protection of the protective layer, the damage to the lower pressing plate 16 is reduced when the workbench 5 is pressed downward, and the service life of the lower pressing plate 16 is greatly extended;

[0022] The lower pressing plate 16 matches the workbench 5. When the punch 9 completes tablet pressing and performs the rising work, the workbench 5 is pressed down to a suitable position through the connection between the above-mentioned control component and the punch 9 and the workbench 5, so that the tablet protrudes from the workbench 5, which greatly facilitates the tablet removal work. A plurality of reset mechanisms are fixedly connected to the upper end surface of the base 1, and the reset mechanism includes a fixed outer layer 17. A notch 27 is arranged on the upper end surface of the fixed outer layer 17. A spring 18 is fixedly connected in the notch 27. A push block 19 is fixedly connected on the upper end surface of the spring 18. The push block 19 is slidably connected in the notch 27. The push block 19 is fixedly connected to the workbench 5. Through the lifting action of the above-mentioned reset mechanism, the workbench 5 that has been pressed down returns to its original position, which is convenient for the next round of feeding and stamping work. A tablet collecting component is provided on the workbench 5. The tablet collecting component includes four symmetrically arranged fixed blocks 20, and the four fixed blocks 20 have a total of There are two rail rods 21 fixedly connected to the workbench 5, and the two rail rods 21 are slidably connected with a tablet pusher 22. A telescopic motor 23 is fixedly connected to the upper end surface of the workbench 5. The telescopic motor 23 is a prior art. By turning on the motor, the motor shaft is driven to be telescopic. The motor shaft of the telescopic motor 23 is fixedly connected to the tablet pusher 22. A tablet collecting hole 24 is provided on the workbench 5. A tablet producer 25 is fixedly connected to the lower end surface of the workbench 5. The tablet producer 25 is made of dust-proof glass material, so that the formed tablets will not be polluted by the environment when passing through the tablet producer 25, thereby causing the quality of the tablets to decrease. The tablet producer 25 is directly opposite to the tablet collecting hole 24. Through the above structure, the tablet pusher 22 automatically pushes the tablets into the tablet producer 25, reducing the environmental impact caused by manual operation, greatly improving the quality of the tablets, and at the same time enabling the tablets to be collected in time when they are protruding, thereby shortening the time for the next round of feeding and stamping, greatly improving the work efficiency.

[0023] During the use of the utility model, after the staff completes the medicine stamping and forming work, the top lifting device 2 pulls the punch 9 to the specified position. During the pulling process of the punch 9, the lifting rod 15 is driven to rise through the connecting rod 14, and the lifting rod 15 is eccentrically arranged relative to the rotating disk 13 to make the rotating disk 13 rotate, so that the other end of the rotating disk 13 drives the lower pressing plate 16 to press down. Since the lower pressing plate 16 matches the workbench 5, the lower pressing plate 16 can press the workbench 5 down to a suitable position, and at this time The formed tablets are supported stably by the tablet pressing column 8 and will protrude from the die hole 6, which greatly facilitates the subsequent tablet removal work. At this time, the staff turns on the telescopic motor 23 to push the tablet pusher 22 to move along the direction of the rail 21 toward the tablet collecting hole 24, thereby pushing the formed tablets into the tablet collecting hole 24, so that the tablets fall out of the tablet output device 25 and are collected, and then the tablet collection work is completed. Then the telescopic motor 23 is reset to pull the tablet pusher 22 back to the position before the tablet collection work. When the staff is performing the next round of tablet feeding and punching, the punch 9 will not be interfered by the pusher 22, so that the tablet pressing work cannot be completed. During the operation of collecting tablets, the tablets are always automatically collected by the pusher 22 driven by the telescopic motor 23. Compared with manual collection, this greatly speeds up the collection of formed tablets, so that the tablets will not stay on the workbench 5 for too long, prolonging the collection time, causing the next round of tablet production work to stop, thereby affecting the tablet forming efficiency, and reducing the impact of manual operation, making the formed tablets less susceptible to damage, and improving the quality of the tablets. Before the next round of feeding, the punch 9 is reset and descended to the initial position, the workbench 5 loses the pressure of the lower pressure plate 16, and the push block 19 pushes the workbench 5 up and resets to the initial position under the elastic force of the spring 18. At this time, the workbench 5 is higher than the tablet pressing column 8 to form a mold, which greatly facilitates the staff to carry out the next round of feeding work, improves the work efficiency of tablet production, and greatly meets the staff's use needs.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
