three-layer tablet pressThere are special requirements in some aspects, and the structure is also targeted. There are some precautions in use, which can be analyzed as follows.
The structure and application requirements of the three-layer tablet press, if the plate is pressed in a special-shaped mold, the mold has certain positioning requirements, such as square, triangular, oval and other shapes. The upper punch of the turntable of the three-layer tablet press has requirements for the structure of the tablet press. Because the upper punch needs to have direction keys and cooperate with the upper punch of the turntable during the installation process, the requirements for the mold are improved. The lower punch of the three-layer tablet press does not leave the middle die hole during the working process, and no other processing is required. The punch rod of the special-shaped molded tablet cannot rotate freely, but can only move up and down along the upper and lower guide rails. When the turntable is driven, the punch and the guide rail slide and rub, causing the punch and the guide rail to wear each other. Therefore, when we use the three-layer tablet press, we should pay attention to lubrication, remember to do a good job in daily work, and check regularly for looseness Or wear, when the punch and the middle die are affected, they cannot operate and produce.
The special-shaped die can only be installed after the punch and the middle die of the three-layer tablet press are accurately positioned, and then the punch is tightened in the middle die hole to avoid inaccurate positioning. After all the dies are installed, turn the disc by hand for a few times, and then operate after there are no special circumstances. If the tablets pressed by the three-layer tablet press will crack and the hardness will be uncoordinated, it is mainly due to the reasons of the materials, such as the density and humidity of the materials are not adjusted properly, and the materials will be pressed after adjustment.
When pressing tablets in a three-layer tablet press, the pressure must be adjusted well. If the pressure adjustment for the first filling is not appropriate, the hardness of the lower half will be different. The second filling is done by pressing again, so the pressure adjustment determines the formation of the tablet.
