1. Dose control

 

Various tablets have different dosage requirements. Large dosage adjustment is achieved by choosing different punch diameters. After choosing the size of the die, the micro dosage adjustment is to adjust the depth of the punch into the middle die hole, thus changing the actual length of the middle die hole after sealing, so as to achieve the adjustment of the die hole.

 

The purpose of filling volume of Chinese medicines. Therefore, there should be a mechanism to adjust the original position of the punch in the die hole on the tablet press to meet the requirement of dose regulation.

 

2. Control of tablet thickness and compaction degree

 

The dosage of the drug is determined according to the prescription and pharmacopoeia and cannot be changed. In order to meet the requirement of storage, storage and disintegration time, the pressure of a certain dose is also required during tablet pressing, which will also affect the actual thickness and appearance of tablets. Pressure regulation during tableting is essential. This is achieved by adjusting the downward flow of the upstream punch in the die hole. Some tablet presses not only have upstream and downward motion, but also downward upward motion. The upstream and downward relative motion completes the tablet pressing process together. But the pressure regulation mostly realizes the pressure regulation and control by adjusting the upstream and downward flow mechanism.
