Abstract In recent years, China has been promoting energy-saving emission reduction。 A new type of energy saving and environmental protection building material polyurethane thermal insulation board has been paid attention to by the construction industry。In this paper, according to the general composition and production process of the polyurethane thermal insulation board production line and the working principle and control requirements of the track cutting,a polyurethane insulation board track cutting control system flow chart has been designed。The ladder diagram of the control system of the polyurethane thermal insulation board was compiled by GX Developer。And use GX Simulator to simulate and debug。The control system can work in automatic, semi-automatic and manual operation state。The polyurethane thermal insulation board can be fixed length and cut off by the length encoder according to the requirement of the board length parameter。Under the non-stop of the production line,the continuous polyurethane products can be cut automatically。At the same time ,it can absorb the dust generated by cutting。The design of the control system can improve the efficiency of the fixed length quantitative cutting of the polyurethane insulation board。The automation degree of the control system is greatly improved and the production efficiency is improved。
