[0034] Initially, the pushing shaft 23 is against the inclined rod 21, and the baffle 17 is in the open state. The staff pours the drug powder into the granulator 15, and the granulator 15 presses the drug powder into flakes. The flakes fall into the granulator 16, and the granulator 16 crushes the flakes into small particles. The small particles fall into the feeding frame 20, and the telescopic rod of the electric push rod 19 is controlled to extend, driving the feeding frame 20 to move to the right. The feeding frame 20 drives the connecting block 22 and the pushing shaft 23 to move to the right. The pushing shaft 23 no longer presses against the inclined rod 21, and the baffle 17 moves downward under the action of its own gravity. The baffle 17 is closed, and the feeding frame 20 can push the small particles into the main static mold 4. The telescopic rod of the electric push rod 19 is controlled to shorten, driving the feeding frame 20 and the pushing shaft 23 to the left. The pushing shaft 23 contacts the inclined rod 21 in the process of moving to the left, and then the pushing shaft 23 pushes the inclined rod 21 to move upward, and the inclined rod 21 drives the baffle 17 to move upward, opens the baffle 17, and the small granule medicine in the granulator 16 falls into the feeding frame 20, controls the telescopic rod of the hydraulic cylinder 81 to extend, drives the first connecting plate 82 to move downward, and the first connecting plate 82 drives the lifting plate 7 to move downward, and the lifting plate 7 drives the active mold 8 to move downward, and the active mold 8 and the main static mold 4 are molded to make the small granule medicine into tablet medicine, and then controls the telescopic rod of the hydraulic cylinder 81 to shorten, drives the active mold 8 and the push plate 34 to move upward, and the push plate 34 pushes the push rack 31 to move upward, and the second spring 32 is compressed, and the push rack 31 presses the materials in the main static mold 4. The finished tablet medicines are pushed out, which is convenient for collecting the finished tablet medicines. The telescopic rod of the electric push rod 19 is controlled to extend again, driving the feeding frame 20 to move to the right. The feeding frame 20 pushes the finished tablet medicines on the main static mold 4 into the filter frame 37. The powder in the tablet medicines will pass through the filter frame 37 and fall into the collection box 36. The tablet medicines remain in the filter frame 37, separating the tablet medicines and the powder, which is convenient for collecting tablet medicines. At the same time, the feeding frame 20 will push the small particle medicines into the main static mold 4, control the telescopic rod of the hydraulic cylinder 81 to extend, drive the active mold 8 and the push plate 34 to move downward, and the push plate 34 no longer pushes the pusher frame 31. Under the action of the second spring 32, the pusher frame 31 moves downward. When the main static mold 4 and the active mold 8 need to be replaced, The telescopic rod of the control hydraulic cylinder 81 is shortened, driving the lifting plate 7 and the active mold 8 to move upward, so that the lifting plate 7 and the guide rail 10 are aligned. The lifting plate 7 can also drive the contact block 25 to move upward. When the inclined position on the contact block 25 contacts the contact rod 28, under the action of the contact rod 28, the contact block 25 moves to the right, the first spring 26 is compressed, and the contact block 25 drives the horizontal clamping rod 24 to move to the right. The horizontal clamping rod 24 moves out of the first clamping groove, releasing the active mold 8. The horizontal clamping rod 24 drives the L-shaped clamping rod 29 to move to the right. The L-shaped clamping rod 29 moves out of the second clamping groove, releasing the main static mold 4, and then pushes the auxiliary movable mold 11 backward. The auxiliary movable mold 11 is pushed between the two lifting plates 7. The auxiliary movable mold 11 pushes the active mold 8 backward and pushes the active mold 8 out.To facilitate the replacement of the active mold 8, the auxiliary static mold 13 is pushed backward and pushed between the first mounting frame 2 and the second mounting frame 3. The auxiliary static mold 13 pushes the main static mold 4 backward and pushes the main static mold 4 out, making it easier to replace the main static mold 4. After the main static mold 4 and the active mold 8 are replaced, the telescopic rod of the hydraulic cylinder 81 is controlled to extend, driving the contact block 25 to move downward. The contact block 25 and the contact rod 28 are disengaged. Under the action of the first spring 26, the contact block 25 moves to the left, and the contact block 25 drives the horizontal clamping rod 24 to move to the left. The horizontal clamping rod 24 is inserted into the first clamping groove on the auxiliary movable mold 11 to fix the auxiliary movable mold 11. The horizontal clamping rod 24 can also drive the L-shaped clamping rod 29 to move to the left. The L-shaped clamping rod 29 is inserted into the second clamping groove on the auxiliary static mold 13 to fix the auxiliary static mold 13.
