Abstract：The conveyor belt speed of extruder is the key factor affecting product quality, so it is very important to keep the output speed of conveyor belt. The speed pulse signal output by laser speedometer is used as pulse generator. Using the high- speed count pulse function of Siemens 200 PLC to count the pulse in the unit time, and then convert the pulse quantity within the unit time into the analog speed control signal of synchronous conveyor belt frequency converter. The application program of the extruder speed acquisition and export conveyor belt speed is designed, the advantage of this control method is good real-time and high precision.
