Tablet sugar is a kind of refined sugar powder as the main raw material, adding milk powder, spices and other fillers and starch syrup, dextrin, gelatin and other binders, and is formed by granulating and compressing through a candy tablet machine. It does not need to be heated or cooked, which is the so-called cold processing process. my country's candy tablet press industry needs to continue to develop in the direction of high speed, high output, high density, modularization, automation, and large-scale development. The tablet making principle of the tablet press is as follows:

The dosage requirements of different tablets are different, by selecting the dies of the rotary high-speed tablet press with different punch diameters. After the size of the die is selected, the actual length of the die hole can be changed by adjusting the depth of the lower punch extending into the die hole, and the filling volume of the drug in the drug hole can be adjusted.

Therefore, a mechanism for adjusting the initial position of the lower punching hole should be provided on the tablet press to meet the dosage adjustment requirements. Since there is always a difference in specific volume during the preparation of different batches of medicinal powder, this adjustment is very necessary.
