Characteristics of printing and dyeing machinery

Tension control is an important control link in warping,sizing,manufacturing,printing and dyeing machinery and other equipment.With the development of control technology,new speed control technologies such as frequency converter and servo control have been widely used in printing and dyeing equipment.Now most of the printing and dyeing equipment tension control mode has three kinds,namely:inverter control.

The magnetic powder clutch is composed of a transmission unit(coupling input shaft)and a driven unit(coupling output shaft).Between the two groups of units,granular magnetic powder with a diameter of about 40um is filled.When the magnetic line is not electrified,the torque will not be transmitted from the transmission unit to the driven unit;Using the principle of linear relationship between synchronous speed of motor and frequency of input power supply,frequency conversion speed regulation converts 50 Hz power supply into AC power supply with adjustable frequency through rectification and counter current link to supply three-phase asynchronous motor.

The servo control has the characteristics of wide and smooth speed range,hard mechanical characteristics and good regulation characteristics,fast response characteristics,high reliability and strong pressure resistance.
