Operation principle of automatic pill tablet press machine

Various types of pills have differing dose requirements and large dose transfers can be accomplished by selecting a die with a different punch diameter. After selecting the die size, micro-dose adjustments are made by adjusting the depth of the lower punch into the middle die hole to alter the practical length of the middle die hole after the reverse seal, thus adjusting the die hole

The objective is to make up the amount of herbal drug. Thus, there should be a mechanism to adjust the original position of the punch in the upper die hole of the tablet press to meet the requirements of dose adjustment.

2. Tablet thickness and compaction control

The dose of the drug is determined by the prescription and the pharmacopoeia and cannot be changed. In order to meet the required storage, transport, storage and breakdown times, the pressure of the dose must also be applied during the tablet pressing process, which also affects the thickness and appearance of the tablets in practice. The pressure must be regulated during the tablet pressing process. This is done by adjusting the number of downwards-pointing punches in the die hole. Some tablet presses have not only an upward and downward movement during the pressing process, but also a downward movement. The compression process is completed by absolute upward and backward movement. However, the pressure regulation is mainly done by regulating the upward and downward low pressure mechanisms.

Installation of tablet press die

(1)To attach the upper punch: loosen the lower punches fixing screw, turn the handscrew to raise the lower punch lever to its maximum position, insert the lower punch lever into

the hole of the lower punch lever (take care to align the notch slope of the lower punch lever with the lower punch fixing screw and to insert it to the end) and finally tighten the lower punch fixing screw.

(2)To fit the upper punch: release the lower punch fixing screw, turn the hand wheel to raise the lower punch lever to its fullest position, insert the lower punch lever into the hole in the lower punch lever (take care to align the notch slope of the lower punch lever with the lower punch fixing screw and insert it to the end) and finally tighten the lower punch fixing screw.
