The upper limiting track 13 and the lower limiting track 22 are concavely undulating, and the inside is movably connected to the head of the punch 14, thereby controlling the undulation of the punch 14. When the punch 14 moves to the lowest position on the lower limiting track 22, the punch 14 is inserted into the middle die hole 23 and is in the powder filling stage. When the punch 14 moves to the tablet pressing wheel position, the upper eccentric wheel cooperates with the lower eccentric wheel to squeeze the powder in the middle die hole. After the powder is squeezed into tablets, as the punch 14 moves to the highest position of the lower limiting track 22, the tablets are pushed out of the middle die hole 23, and then enter the Z-shaped discharge tube 24 through the through hole 25. As the punch 14 continues to move, the tablets are intercepted by the tube wall.
