1. This machine is an automatic rotary continuous tablet press, widely used in pharmaceutical, chemical, ceramic, food, electronics, plastic and powder metallurgy industries.
2. This machine is suitable for pressing various granular raw materials into tablets, but is not suitable for pressing semi-solid, moist molecules and non-granular ultra-fine powders.
Working principle and structural characteristics
1.The machine is driven by an electric motor (stepless speed regulation controlled by a frequency converter) → pulley drive → worm drive → the main shaft drives the turntable to rotate clockwise.
3. When the machine is working, the turntable drives 19 pairs of dies to rotate clockwise, and the upper and lower dies move up and down along the curved track, and the pressure action is completed by the pressure wheel.
4. The upper and lower pressure wheel devices adopt rolling friction, which is beneficial to reduce working resistance and power consumption.
5. The safety unloading device of the pressure wheel is on the lower pressure wheel shaft and is balanced by a spring. Its working pressure is adjusted by the spring sleeve. When the pressure is over, the spring sleeve automatically jumps to unload and also plays a role in protecting the punch rod.
6. The control and adjustment of each part such as filling, tablet thickness and speed are all centrally controlled, which is easy to operate.
7. This machine adopts closed oil-lubricated worm and worm gear transmission to reduce power loss and extend its service life.
8.The peripheral components of this machine adopt a fully enclosed structure, which completely separates the sealed tablet pressing chamber and the driving mechanism, prevents dust from flying and avoids cross contamination of oil.
9. Equipped with a dust collector, which can automatically remove dust.
