Tablet pressing is a machine that places granular or powdery materials in a die hole and presses them into tablets by a punch. It is especially suitable for small batch production. It is characterized by adjustable speed, material filling depth, tablet thickness, The machine is equipped with a mechanical buffer, which can avoid dust generated during operation, prevent adhesion and blockage, and can recycle raw materials for reuse.
It is understood that in addition to the traditional single-stage tablet presses currently on the market, the rotary tablet presses can automatically identify quality problems such as missing corners and loose tablets due to their good tableting effect and high tablet density uniformity. Elimination, effectively reduce the phenomenon of splinter, and the machine has low vibration, low noise, low energy consumption, high efficiency and accurate tablet weight, which is favored by the market and widely used in medicine, health care products, food and other industries.
The industry pointed out that in order to meet the requirements of storage, transportation, preservation and disintegration time limit, there are corresponding requirements for the pressure of a certain dose during tableting, otherwise the actual thickness and appearance of the tablet will be affected. Therefore, pressure regulation during tableting is required. When users use the tablet press, they generally need to debu.
Tablet production adjustment
This method is to first turn the handwheel to make the lower punch rise to the position, and observe whether the lower punch surface is in line with the plane of the middle die (high or low will affect the output). If it is not, loosen the thumb screw and loosen The gear pressing plate is transferred to the upper adjusting gear, so that the lower punch surface is flush with the plane of the middle die, and then the pressing plate is still pressed up, and the butterfly screw is tightened.
After the completion, the user can shake the hand wheel by hand, and run the empty car for more than ten revolutions.
Adjustment of filling depth
According to the industry, the adjustment of the filling depth is the adjustment of the weight of the tablet. Turn the lower adjusting gear to the left to raise the lower punch rod, and the filling depth is reduced (the weight of the tablet is reduced). After adjustment, press the gear tooth pressure plate and tighten the thumb screw.
Pressure adjustment
The adjustment of the pressure is the adjustment of the hardness of the tablet. First loosen the connecting rod lock nut, turn the upper punch rod, turn left to move the upper punch rod downward, the pressure will increase, and the hardness of the extruded tablet will increase; otherwise, Turning to the right will reduce the pressure and the hardness of the tablet. After adjusting, use a wrench to clamp the lower part of the upper punch rod, and then lock the connecting rod locking nut.
When the adjustment of the die is basically completed, start the motor to test more than ten pieces, check the quality of the piece weight, hardness and surface finish, if it is qualified, it can be put into production. During the production process, the quality of the tablets must be checked at any time and adjusted in time.
In addition, in order to make the pharmaceutical tablet press operate more stably, users also need to pay attention to the maintenance of the equipment in peacetime. For example, pay attention to the lubrication of the friction surfaces of various moving parts. Before use, all oil cups, oil holes and friction surfaces must be lubricated, and run empty to make each friction surface covered with oil film, and then put into use; check regularly; Whether the screws are loose should also be checked frequently during the work process. If they are loose, tighten them immediately to avoid malfunctions.
