We first turn the hand wheel to raise the lower punch to a high position, and then observe whether the surface of the lower punch is aligned with the plane of the middle mold. The mouth surface is aligned with the plane of the middle mold, and then the pressure plate is still pressed and the thumb screw is tightened. At this time, shake the hand wheel by hand to drive the empty car more than ten laps. If the machine is operating normally, you can add a stress test and make the next adjustment.

Loosen the connecting rod lock nut and turn the upper mandrel to the left to move the upper mandrel downwards, increase the pressure, and increase the hardness of the extruded tablet; otherwise, the pressure will decrease and the hardness of the tablet will decrease. After adjustment, clamp the lower six sides of the upper mandrel with a wrench, and still lock the connecting rod lock nut. At this point, the adjustment of the mold is basically completed, and then the motor is started to test more than ten pressures. If the quality of unit weight, hardness and surface finish is checked, it can be put into production. During the tableting production process, the quality of the tablets must be checked at any time and adjusted in time.
