The structural principle of rotary tablet press
Date: 2024-08-16Read: 4
In the pharmaceutical industry, a tablet press is a very important equipment that can compress powdered drugs into tablets, making it easy to carry and store. Rotary tablet press is a common type of tablet press that consists of multiple components, including feeding mechanism, tablet press mechanism, discharge mechanism, lubrication system, etc. The entire equipment is made of stainless steel and meets GMP standards.
The feeding mechanism mainly consists of a feeding port, a speed controller, a hopper, etc. The feeding port can adjust the feeding amount, and the speed controller can control the feeding speed. The capacity of the hopper can be adjusted according to production needs.
The tablet pressing mechanism is the core part of the entire equipment, consisting of a feeding wheel, a pressing wheel, a mold, a photoelectric switch, etc. The feeding wheel sends the powder that has passed through the feeding mechanism into the mold, while the pressing wheel compacts the powder into flakes. The mold determines the surface shape and thickness of the tablets. The photoelectric switch can monitor the quality of tablets and ensure their consistency.
The discharge mechanism consists of a tablet discharge switch, a tablet discharge baffle, etc., which can discharge the compressed tablets out of the equipment. The entire emission process is automated, which can greatly improve production efficiency.
The lubrication system mainly consists of lubrication oil tanks, lubrication pumps, etc., which can lubricate the pressure wheel and mold, reduce frictional resistance, and extend their service life.
The process principle of rotary tablet press can be mainly divided into three steps: feeding, pressing, and discharging.
First, the feeding mechanism sends the powder into the hopper through the feeding port, and adjusts the feeding amount and speed. Subsequently, the powder is fed into the mold through the feeding wheel, and the mold is responsible for compacting the powder into flakes. During the compression process, the pressure wheel applies pressure to compact the powder into shape, while the photoelectric switch checks the quality of the tablets to ensure they meet the specified standards. Finally, the compressed tablets are automatically discharged from the equipment through the discharge mechanism.
The process principle of rotary tablet press is relatively simple, but multiple settings are required in practical operation. For example, parameters such as hopper capacity, feed rate, and pressure of the pressing wheel need to be adjusted to achieve satisfactory production results. At the same time, it is also necessary to regularly maintain and upkeep the equipment to ensure its normal operation.
