The mechanism mode of lifting roller of loop is proposed using SimMechaics module in MATLAB/Simulink. Based on the method of node analysis, Simulink is utilized to establish pneumatic system model of lifting roller of loop. The whole simulation model is established combining mechanism model and pneumatic model according to their parameter relationship , so that the full mechanism simulation loop model of lifting roller of loop is obtained. According to the results of simulation, pneumatic circuit of the looping lifting roller is improved effectively, which provides significant reference for the improvement of vertical loop of bar mill.
