The structure of the tablet press

The earliest tablet press is composed of a pair of stamping die, the punch moves up and down to press granular materials into sheets, this machine is called single stamping sheet machine, later developed into electric flower basket type tablet press. The working principle of the two kinds of tablet press is still based on the manual die one-way pressure, that is, the pressure plate is fixed down, only upward movement pressure. This way of pressing the tablets, due to the up and down force is not consistent, resulting in the internal density of the tablets is not uniform, easy to produce cracks and other problems.

In view of this shortcoming of unidirectional tablet press, a rotary multi-impact bidirectional tablet press was born. This kind of tablet press presses down at the same time evenly pressurizes, causes in the medicine particle air to have the abundant time to escape the mold hole, enhanced the tablet density uniformity, reduced the lobes phenomenon. In addition, rotary tablet press has the advantages of small vibration, low noise, less energy consumption, high efficiency and accurate weight.

Rotary tablet press is a machine in which granular materials are pressed into tablets by means of a certain track of circular lifting and lifting movements of several sets of stamping dies all distributed on the turntable. And punch with the turntable rotate speed of 60 m/min or called high-speed rotary tablet press machine, the high-speed rotary tableting machine has forced feeding machine, the machine is controlled by PLC, automatically adjust the pressure, control weight, eliminate waste pills, print data, display downtime, and other functions, in addition to can control weight difference in a certain range, quality problems such as lack of Angle, loose lobes can automatically identify and eliminate.

The shape of the piece that press piece machine place presses, it is oblate circle more at first, develop for the shallow circular arc of fluctuation two sides later and deep circular arc, this is for the need of coating. With the development of special-shaped tablet press, ellipse, triangle, oblong, square, diamond, circle and other tablets are produced. In addition, with the continuous development of the preparation, due to the requirements of compound preparation and timed release preparation, special tablets such as double layer, triple layer and core coating are made, which need to be completed on a special tablet press.
