[0019] 1. The cleaning mechanism solves the problem of powder residue remaining on the surface of the tablet press after tableting. After tableting is completed, the control valve is adjusted so that the cylinder restores the connecting rod to the initial position. The hard piston is restored to the initial position under the action of spring 2, and the hard piston blocks the through hole of the shaped shell again to prevent the powder in the connecting pipe 2 from continuing to enter the shaped shell. The tablets and residue on the hard piston are blown into the discharge port under the blowing action of the connecting pipe 3, and fall into the receiving box through the discharge port. The tablets are left on the surface of the sieve plate under the screening of the sieve plate, and the powder residue flows out from the lower end opening of the receiving box.

[0020] 2. The pressurizing mechanism realizes the rapid tableting of the powder. Before tableting, the powder is poured into the storage box, and then the control valve is started. Under the pressurized action of the air pump, the compressed gas enters the cylinder through the connecting pipe 1. Under the action of the cylinder, the connecting rod descends. As the connecting rod descends, the feeding shell descends at the same time. After the lower end surface of the feeding shell contacts the upper end surface of the hard piston, as the feeding shell continues to descend, the hard piston descends in the shaping shell. When the through hole provided on one side of the feeding shell coincides with the through hole of the shaping shell, the powder in the storage box enters the connecting pipe 2 with the compressed gas, and then enters the feeding shell from the through hole of the shaping shell through the connecting pipe 2. When the hard piston reaches the surface of the bottom plate, the hard piston stops moving, and the feeding shell stops moving at the same time. The connecting rod in the feeding shell continues to descend, and the powder entering the feeding shell is tableted. This mechanism realizes rapid tableting and improves work efficiency.
