Ingeniously, applicability is wider, without improving existing tablet press machine on a large scale, effectively saves improving cost, while can effectively improve tabletting
Success rate.
Preferably, the buffer is the lubricating oil of high viscosity；Highly viscous lubricating oil has larger in flowing
Viscosity, biggish pressure can be resisted；In biggish pressure range, the steady of tablet compression is effectively ensured；Make simultaneously
Obtaining has minimum frictional force between dashpot and pressure stabilizing bar, and then reduces error.
Pressure scale is equipped with preferably, carving on the axis of the pressure stabilizing bar；Variation and permanent magnetism due to magnetic repulsion
Spacing between material is not once linear relationship, therefore can more accurately recognize tablet institute by observing pressure scale
The pressure received.
It pressurizes preferably, mold is inverted, pressure stabilizing bar is contacted with loading plate, and bottom plate is contacted with pressured column；It can read
More accurate pressure value；The factor that buffer flows into buffering groove groove wall because gravity is spontaneous can be excluded by being inverted pressurization, to make to press
Power shows more acurrate.
