[0027] The pressing mechanism includes a movable plate 61, six movable plates 61 are slidably connected to the turntable 53, two supporting springs 62 are connected between the turntable 53 and the six movable plates 61 through hooks, the supporting springs 62 are sleeved on the movable plate 61, weights 63 are welded on the six movable plates 61, four long rods 64 are welded on the six movable plates 61, two long rods 64 located on the same side of the same movable plate 61 are the same group, a pressing plate 65 is slidably connected between the two long rods 64 in the same group, two pressing plates 65 located on the same movable plate 61 are a group, the sides of the two pressing plates 65 in the same group away from each other are respectively in contact with the two adjacent crushing knives 54, and two reset springs 66 are connected between the movable plate 61 and the two pressing plates 65 in the same group through hooks.

[0028] Preferably, a knocking mechanism is also included, and the box body 2 is provided with a knocking mechanism, and the knocking mechanism includes an annular cam 71, one end of the rotating shaft 52 is fixedly connected to the annular cam 71, and the annular cam 71 is located outside the box body 2, and four fixed frames 72 are fixedly connected to the outer wall of the box body 2, and the four fixed frames 72 are slidably connected to movable frames 73, and two return springs 74 are connected between the fixed frames 72 and the movable frames 73, and the return springs 74 are sleeved on the movable frames 73, and the four movable frames 73 are fixedly connected to impact frames 75, and the box body 2 is located between the four impact frames 75, and the four movable frames 73 are fixedly connected with push rods 76, and the ends of the four push rods 76 close to each other are provided with extrusion arc surfaces.

[0029] Initially, two adjacent crushing knives 54 squeeze two pressure plates 65 of the same group, the return spring 74 is in a compressed state, the annular cam 71 squeezes one of the push rods 76, the fixing frame 72, and the impact frame 75, and one group of return springs 74 is in a stretched state. First, the staff starts the servo motor 51 and pours the drug raw materials into the box body 2 through the feed hopper 3. The drug raw materials will fall down onto the movable plate 61 and the pressure plate 65. The servo motor 51 will drive the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 will drive the rotating disk 53 to rotate. The rotation of the rotating disk 53 will drive the six crushing knives 54, the six movable plates 61, and the six weight plates 61. The six weight blocks 63 and the six groups of pressure plates 65 rotate, and the six weight blocks 63 will move away from each other under the action of centrifugal force.

[0032] When the servo motor 51 drives the rotating shaft 52 to rotate, the rotating shaft 52 will drive the ratchet 81 to rotate. The rotation of the ratchet 81 will push the push rod 85 to move downward. The downward movement of the push rod 85 will drive the connecting frame 82 and the screen frame 84 to move downward, and the return spring 83 will be compressed. As the ratchet 81 continues to rotate, the ratchet 81 will disengage from the push rod 85, and the return spring 83 will reset. The reset of the return spring 83 will drive the push rod 85, the connecting frame 82 and the screen frame 84 to move upward, and reciprocate in sequence, so that the screen frame 84 reciprocates up and down and vibrates, thereby increasing the screening speed of the screen frame 84 for pharmaceutical raw materials, and further improving the processing efficiency of the drugs.
