The main motor of tablet press machine drives the turntable to rotate through AC variable frequency stepless speed regulator and slowed down by a worm. The rotation of turntable drives upper and lower punch to do up and down relative movement under the action of guide rail. The granules or powders are pressed into tablets by filling, prepressing, pressing and discharging. During the whole pressing process, the control system implements automatic control of tablet weight, automatic defective tablet removal, automatic sampling and fault display through detection, transmission, calculation and processing of the pressure signal.

GZPK Series Rotary Tablet Press Machine - Principe

The upper and lower punch heads are driven by punching plate to move clockwise along the upper and lower guide rails. When punch moves to the filling section, the upper punch moves upward to bypass the forced feeder. Meanwhile, the lower punch moves downward under the action of downward cam. At this point, lower punch surface forms a cavity in the gap of middle mold, and powder particles are stirred into the cavity by feeder impellers, and overfilling is achieved when lower punch pass the lowest point of downward cam. The punch plate continues to move, it moves upward when lower punch passes through the cam, push excess powder particles in the cavity out of the middle mold hole and into the quantitative section. The surface of filling cam is horizontal, and lower punch keeps horizontal motion state, excess powder particles on the surface of middle mold are scraped out by the quantitative scraper to ensure consistent filling quantity of the powder particles in each middle mold hole. In order to prevent powder from being thrown out of the middle mold hole, a cover plate is installed behind the quantitative scraper. When middle mold hole moves out of cover plate, the upper punch enters into middle mold hole. When the punch passes through the prepress wheel, achieve pre-pressing; then passes through main press wheel, finish compacting action. Finally, pass through the tablet discharging cam, with upper punch move upward and lower punch push upward to push the finished tablets, tablets enter into tablet discharging device, and the whole pressing process is finished.
