Research On Heat-Setting Machine Tensile Synchronous Control System

To polyester mesh crucial role for paper product quality, which heat setting machine is an important link in the production and processing of polyester net. Heat shaping tender stretching tension control accuracy and quality directly determines the forming process of the product after polyester mesh fabric quality. It is also the main direction of many control field of engineering and technical personnel at this stage of the study.This is in reference to domestic and foreign literatures and real, according to the actual requirement of polyester fabric shaping process, put forward the research method and control method of synchronous control system of tension control based on PLC. Taking PLC as the central control unit, with AC frequency converter on tensile motor and stretching device of motor speed control as the method, the Fuzzy-PID control method is adopted to complete to the heat setting machine tension control of trace and debug. This system adopts modularized structure circular scanning mode, and according to the actual needs of polyester fabric shaping process, research and development of a computer control system, convenient site operation personnel of the production process control, improves the effectiveness of on-site production of automatic control and timeliness.Tension in PLC as the core components of the synchronous control system, especially joined the strategy optimization of defects in the traditional polyester fabric shaping process for tensile rate inconsistent fuzzy PID control, to fill the domestic blank. A computer control system is designed in the control system, provides an interactive interface for it for the field staff, according to the screen display content, quick parameter setting, troubleshooting, and greatly improve the efficiency of polyester fabric shaped.
