[0032] When it is necessary to process tablets with larger particles, the switching screw 14 is manually rotated to drive the switching frame 13 to move backward along the guide rail 12. During the movement, the switching frame 13 will simultaneously drive the synchronization rod A26 and the synchronization rod B38 to move backward under the cooperation of the force plate A28 and the force plate B40, so that the synchronization rod A26 and the synchronization rod B38 respectively drive the control groove 27 and the control plate 39 to move backward.

When the driving gear 8 rotates, the driving gear 8 will also use its own characteristics as an elliptical gear to reciprocately push the transmission gear 11 upward, so that the transmission gear 11 can drive the mounting frame 3 and the tablet pressing mother mold 16 to vibrate reciprocatingly under the action of the buffer spring 4, and the tablet pressing mother mold 16 The medicines extruded inside will fall into the collecting rack 15 by vibration, so that the extruded tablets are taken out from the inside of the device.
