How to adjust the tablet press machine


Tablet press is a kind of machine that puts particles or powder materials in the die hole and presses them into tablets by punch. It is especially suitable for small batch production. It is characterized by adjustable speed, filling depth of materials, tablet shape thickness and mechanical slowness installed on the machine, which can avoid dust generated during operation, prevent sticking and blocking, and recycle raw materials for reuse.

In addition to the traditional single tablet press, the rotary tablet press is favored by the market for its good tablet pressing effect, high uniformity of tablet density, automatic identification and elimination of quality problems such as missing angle and loose split, effective reduction of split phenomenon, low vibration, noise, less energy consumption, high efficiency and accurate weight of tablet. It is widely used in medicine, health care products, food and other industries It is widely used in the industry.

In order to meet the requirements of storage, transportation, preservation and disintegration time limit, there are corresponding requirements for a certain dose of pressure when pressing the tablet, otherwise it will affect the actual thickness and appearance of the tablet. Therefore, the pressure regulation during tablet pressing is essential. When the user is using the tablet press, it is generally necessary to debug the equipment.

Adjustment of tablet output of powder tablet press

This method is to first turn the hand wheel to raise the lower punch to the position, observe whether the lower punch face is flush with the middle die plane (or high or low will affect the chip). If not, loosen the butterfly screw, loosen the gear press plate to transfer the upper adjusting gear, so that the lower punch face is flush with the middle die plane, and then press the press plate up, and tighten the butterfly screw.

After completion, the user can shake the hand wheel by hand and run the idle car for more than ten revolutions. If the machine operates normally, it can be fed for pressure test and further adjustment.

Adjustment of filling depth of tablet press

The adjustment of filling depth is the adjustment of tablet weight. The method is: first loosen the butterfly screw, and then loosen the gear pressing plate. Turn the lower adjusting gear to the left to raise the lower punching core 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.

Pressure adjustment of tablet press

The adjustment of pressure refers to the adjustment of the hardness of the tablet. First, loosen the lock nut of the connecting rod, turn the upper punching core rod, turn left to make the upper punching core rod move downward, the pressure will increase, and the hardness of the extruded tablet will increase; otherwise, turn right to reduce the pressure, and the hardness of the tablet will decrease. After the adjustment, use a wrench to clamp the six sides of the lower part of the upper punching core rod, and then lock the connecting rod lock nut.

After the adjustment of the die is basically completed, start the motor to test more than ten pieces, check the weight, hardness and surface finish of the pieces, and then put them into production if they are qualified. In the process of production, the quality of tablets must be checked at any time and adjusted in time.

In addition, in order to make the tablet press operate better and stably, users also need to pay attention to the maintenance of the equipment at ordinary times. For example, pay attention to the lubrication of the friction surface of all moving parts. Before use, all oil cups, oil holes and friction surfaces must be lubricated, and the friction surfaces can be put into use only after the friction surfaces are covered with oil film when the car is running empty; regularly check whether the screws are loose, and pay attention to the inspection during the working process. If they are loose, tighten them immediately to avoid failure, etc.
