The rotating shaft 139 is fixed to the second crank arm 133 and the upper arm 136 respectively, and one end of the upper arm 136 away from the rotating shaft 139 is arranged in the curved groove of the guide plate 137. When the cam 7 rotates, it can drive the two ends of the crank arm 131 to move up and down, and further drive the second crank arm 133 to swing left and right. The swing of the second crank arm 133 drives the upper arm 136 to swing up and down. When the upper arm 136 swings, one end of the upper arm 136 set in the curved groove of the guide plate 137 can reciprocate along the curved track of the guide plate 137. When the punching cutter 12 completes the punching of the medicine plate, the medicine plate will be pushed to the exit position of the die mounting seat 126.
