Installation of die for core device of tablet press machine

Installation of die for core device of tablet press machine

The good or bad of the pharmaceutical tablet press is mainly determined by the die device. In short, the die device is the core device of the tablet press. Whether it is any form of tablet press, such as tablet press, high-speed tablet press, double-layer tablet press, double-layer tablet press, ring tablet press, candy tablet press, etc., all need it. Attention is paid to the installation of die device!

Before the die device of the rotary tablet press, first of all, the hopper, powder feeder, feeder rack and other parts should be removed, and the working face of the turntable, the die hole and the installed die wiped off one by one, and the preparation work should be done, and the installation should be carried out according to the following steps.

The punch device is not one, but is divided into upper, middle and lower parts.

Medium Die Device: The middle die fastening screw on the turntable is one by one flat with the outer circle area of the turntable, so that the middle die is not loaded to touch the head of the screw. The middle die device is very tight and flat when placed. The middle die punching rod (random tool) can be used to punch through the upper hole for the hammer to gently punch in and the middle die to enter the die. The plane of the hole must not be higher than that of the turntable to be qualified, and then the screw should be fastened.

Up-punching device: The tongue-inserting device should be pulled up at the notch of the upper guide disc, the tail of the middle rod should be coated with vegetable oil, and inserted into the hole one by one. The thumb and index finger should be used to rotate the punch rod to inspect the head's entry into the upper and lower dies and its flexible rotation. No hard rubbing is required to be qualified. The tongue-inserting device should be pulled down after all

Down punching device: Open the small door on the main body and install it on the round hole of the main body. The installation method is the same as the upstream punching device. After installation, the disc must be flattened.

Even after the die is fully assembled, the dismantled parts are assembled in situ, and the test handwheel is rotated by hand to rotate the turntable for 1-2 turns. To observe the ups and downs rushing into the middle die hole and moving on the curve guide, it is necessary to operate the motor flexibly without collision and hard rubbing, so that the empty car can run for 2-3 minutes and then be put into operation smoothly and normally. Production.

Installation steps are key, but adjustment is also necessary. Loosening the connecting rod lock nut, turning the upper punch rod, turning left to make the upper punch rod move downward, the pressure increases and the hardness of the pressed tablet increases; conversely, turning right reduces the pressure and the hardness of the tablet decreases. After adjusting the tablet press, the lower hexagonal part of the upstream core rod is clamped with a wrench, and the connecting rod locking nut is still tightened. Up to now, the adjustment of the die has been basically completed, and then the motor is started to test more than ten pieces, check the weight, hardness and surface finish of the sheet, if qualified, the tablet press can be put into production. In the production process, the weight of tablets must be checked at any time and adjusted in time.
