The multi punch rotary tablet press is a miniaturized machine that automatically rotates and continuously presses tablets. It is equipped with an overload protection device, which can automatically shut down when the pressure is overloaded. This type of tablet press improves the uniformity of tablet density, reduces fragmentation and looseness. The machine has low vibration, low noise, low energy consumption, high efficiency, and accurate tablet weight, making it a popular tablet press in China at present.
Working principle of multi punch rotary tablet press:
The tablet pressing process of a tablet press includes processes such as over filling, quantitative adjustment, pre pressing, main pressing, and tablet dispensing. Install the upper punch rod in the upper mold hole of this machine, the middle mold in the middle layer, and the lower punch rod in the lower mold hole. The power brought by the transmission components rotates the turntable, and at the same time, the upper and lower punch rods move up and down along a fixed track in a regular manner, thus completing the pressing process. This machine is capable of continuous feeding and continuous discharging.
Precautions for multi punch rotary tablet press
Before the first use, carefully read the instruction manual by comparing it with the actual machine before use.
Do not touch the tablet pressing room with your hands or other tools during operation.
Materials must not contain metals or solid substances to avoid damaging the mold.
When replacing the mold, the power should be turned off.
When the machine sound is abnormal, the power should be turned off before checking.
When the machine is not operated for a long time, the mold should be removed and stored separately.
The granulation process of the ingredients before tablet pressing has a significant impact on tablet pressing. The formulation and granulation of auxiliary materials such as drug ingredients, lubricants, fillers, binders, etc. (including the condition of the powder, particle elasticity, powder particle ratio, moisture content, etc.) directly affect the tablet quantity. And often due to improper granulation of ingredients, it cannot be formed into tablets, and even damages the machine. Therefore, this machine cannot be used to compress semi-solid, moist, or particle free ultra-fine powders into tablets. If it is found during use that the pressure has been adjusted to a considerable level but still cannot be pressed into pieces, or if it is pressed into pieces but appears too loose, layered, fragmented, pitted, or powdery. We should identify the reasons and solve them from aspects such as ingredients. Do not blindly adjust and increase pressure, which may damage the machine. In addition, some medicinal materials may not produce tablets with high hardness, but they have a certain degree of toughness and are not prone to breakage when dropped from a height of 1-1.2 meters. Therefore, it is important to meet the requirements of transportation and storage, rather than solely focusing on hardness, in order to avoid excessive compression pressure and damage to the machine.
