Transmission system of tablet press The main drive system is to provide power for the tablet press, which requires that the speed of the main drive system is adjustable, and at the same time it has enough torque, so that the speed is stable and reliable under large impact load. The main drive system mainly includes high-power AC motor, frequency converter, tensionwheel, large pulley, synchronous tooth belt, small pulley, hand wheel, worm gear reducer, main drive shaft and other components. The machine adopts frequency conversion technology to replace the mechanical speed regulation of stepless speed regulating motor. The advantages of frequency conversion speed regulation are energy saving and consumption reduction, reliable control, stable operation and low noise. Inverter itself has over voltage, low voltage and over current multiple protection functions, such as through the output parameters can be for real-time monitoring of actuators, once appear abnormal, protection functio
