When the treatment box 4 vibrates, the first connecting rod presses down the vibration spring, reducing the influence of the vibration of the treatment box 4 on the medicine adding box 5.

[0034] Open the cover 6 of the treatment box 4, put the un-screened traditional Chinese medicine raw materials into the treatment box 4, then tighten the cover 6, start the controller 3. The controller 3 controls the vibration motor 20 to start working. The vibration motor 20 drives the treatment box 4 to vibrate, making the materials continuously roll and move on the screening mesh 7. The screening mesh 7 screens the materials. Coarse particles, lumps and impurities are intercepted above the screening mesh 7. The materials meeting the particle size requirements pass through the screening mesh 7 and fall to the bottom of the treatment box 4. The high-speed camera 8 installed inside the treatment box 4 conducts real-time shooting and monitoring on the working state of the screening mesh 7, and can timely capture whether the screening mesh 7 is blocked;

[0035] The controller 3 controls the servo motor 33 to start. The servo motor 33 drives the rotating rod 34 to drive the turntable 35 to rotate, thereby controlling the traditional Chinese medicine in the treatment box 4 to be transported to the medicine adding box 5 through the connecting pipe 9;

[0036] The materials in the medicine adding box 5 are transported to the pressing holes 19 of the mold 16 through the discharge pipes 10 and the electric control valves 11. The controller 3 controls the opening and closing time of the electric control valves 11 according to the requirements of tablet pressing to achieve quantitative transportation of the materials.

[0037] Specifically, the engaging component includes an installation ring 21, a moving member 22, a first return spring 23, a push rod 24, a second return spring 25, and an engaging plate 26. The engaging plate 26 is fixedly connected to both sides of the screening mesh 7. A connection groove 27 is formed on the installation ring 21. A through groove 28 is formed on one side of the connection groove 27. The first return spring 23 is installed in the connection groove 27, and the other end of the first return spring 23 is connected to the moving member 22. The second return spring 25 is sleeved on the push rod 24. A push handle 29 is provided on the push rod 24.

When installing the screening mesh 7, press down the screening mesh 7, and the engaging plates 26 on both sides of the screening mesh 7 penetrate the through groove 28. The engaging plates 26 are in contact connection with the inclined surface at the other end of the moving member 22, which can push the moving member 22 to move. The moving member 22 compresses the first return spring 23. When the engaging plate 26 is completely engaged in the through groove 28, the first return spring 23 releases elastic potential energy to push the moving member 22 to move, so that the moving member 22 is engaged with the engaging plate 26.

[0039] The first weighing sensor 32 can monitor the feeding amount per unit time in real time, and the second weighing sensor 36 can monitor the discharging amount per unit time in real time. By comparing the feeding amount and the discharging amount per unit time, the screening efficiency is calculated. The control system calculates the screening efficiency in real time according to the data fed back by the sensors and dynamically adjusts the screening parameters. The calculation formula: Screening efficiency (%) = (discharging amount / feeding amount) × 100%.

[0040] In the above embodiment, a controller 3 is installed on the support frame 2, and the controller 3 is electrically connected to the electric control valve 11, the high-speed camera 8, the servo electric cylinder 12, the electric push rod 17, the vibration motor 20, the first weighing sensor 32, the servo motor 33, and the second weighing sensor 36 respectively.
