The Adjustment Of Sheet Output, Pressure And Filling Depth Of The Single Tablet Press Machine

2022-09-11

1. Adjustment of film output

Turn the hand wheel to make the lower punch rise to the highest position, and observe whether the lower punch surface is flush with the plane of the middle die (whether it is high or low will affect the chip output). If it is not flush, loosen the butterfly screw, loosen the gear pressing plate, and then move the upper adjusting gear to make the lower punch surface flush with the plane of the middle die, and then press the pressing plate still, and tighten the butterfly screw.

At this point, shake the hand wheel by hand, and run the car empty for more than ten revolutions. If the machine operates normally, you can add material for pressure test and carry out the next adjustment.

2. Adjustment of filling depth (i.e. adjustment of tablet weight)

Loosen the butterfly screw and loosen the gear pressing plate. Turn the lower adjusting gear to the left to raise the lower core punching rod, and the filling depth will be reduced (the weight of the tablet will be reduced). After adjustment, press the gear pressing plate and tighten the butterfly screw.

3. Adjustment of pressure (i.e. adjustment of tablet hardness)

Loosen the locking nut of the connecting rod, turn the upper core punch to the left to move the upper core punch downward, then the pressure increases and the hardness of the pressed tablets increases; On the contrary, turning to the right will reduce the pressure and the hardness of the tablets. After adjustment, use a wrench to clamp the hexagon at the lower part of the upper punch rod, and still lock the connecting rod locknut. At this point, the adjustment of the die is basically completed, and then start the motor to test more than ten pieces. Check the weight, hardness and surface finish of the pieces. If they are qualified, they can be put into production. During the production process, the quality of tablets must still be checked at any time and adjusted in time.
