Research on the Detection and Control System of Rubber Extruder

针对国内橡胶挤出机自动化程度低、生产效率低的现状,选用热电偶温度传感器、超声波位移传感器和压力传感器,采用虚拟仪器、可编程控制器、工业以太网、计算机系统集成等技术构建了橡胶挤出机实时检测与控制系统.系统实现了挤出机橡胶挤出过程的温度控制、挤出量的测量与控制,同时实现了故障实时报警、生产数据自动生成、存储与报送功能.系统运行表明:橡胶挤出机的自动化程度和生产效率得到显著提高,运行可靠.

In view of the present low level automation and production efficiency of rubber extruder in China,a real-time detection and control system of rubber extruder was developed by using thermocouple temperature sensors,ultrasonic displacement sensors,pressure sensors,virtual instruments,programmable logic controllers(PLC),industrial Ethernet technology and computer system integration.The system can control not only the temperature of the rubber extrusion process,but also the measurement and quantity of the extrusion.At the same time,the system can realize the real-time alarm of fault,automatic generation,storage and delivery of production data.The application of the system shows that the automation degree and production efficiency of the rubber extruder is improved,and the system runs reliably.
