Working Analysis Of Tablet Press
Apr 11, 2022
The high-speed tablet press is still a normal tablet press, but the basic principles of the tablet press operation are similar. The working principles of the tablet press include filling, quantitative, pre-pressing, main pressing, and tableting. The upper and lower punches are driven by punching discs, and the upper and lower dies move from left to right along the guide respectively. When the punches move to the filling section, the upwardly moving punches move around the forced feeder. At the same time, the lower punches pass through the role of the cam. Adjust the downward movement to form a cavity on the surface and the die hole, the dust particles of the rotor fill the cavity, and after filling the cavity, pull the cam to form too many punching holes.
The punch of the tablet press continues to move while the lower punch moves upward gradually, particle filling of the cam, and overdispersion in the cavity is an average quantification of the extrusion die hole. Quantified partial filling, the upper surface of the filling cam is horizontal, as long as the punch keeps moving horizontally, the drug and excess powder particles are evenly scratched on the upper surface of the mold. . The protective cam pushes down on the handle, and the upper handle is moved down by the cam. When the die hole is moved from the cover, the upper handle enters the middle die hole.
The movement of the upper and lower punches makes the tablet quite complete, mainly through the pressure of the pressing wheel to carry out complete compaction. After that, through a cam, the tablet pressing of the die hole of the tablet press is averagely output to the device, and the pressure of the die Complete the entire process.
