To study the designing method for the automatic control system and HMI of corrugated single facer. Based on PLC and touch screen HMI technology, the overall design scheme of the control system for the single facer was made, and the main technological parameters such as paper temperature, corrugating pressure and the quantity of glue were controlled and displayed. The experiment verified that the control system could automatically control the production of the single facer, and the HMI operation was quite easy. Through automatic control of the main technological parameters of the single facer, the production costs could be effectively reduced and the product quality could be improved.
