摘要
Abstract
Aimed at the tension of the entry and exit of machine direction orienter produced by the two-way stretch polyester having important influence in the quality of the film ,a closed-loop roll tension control system was proposed .The feedback signal of the linear displacement sensor fluctuated with the moving roll ,then the difference between this signal and the standard signal was delivered to the fre-quency converter ,and the motor speed was controlled by the signal from the frequency converter .Fi-nally ,the purpose of closed-loop control was achieved .The sensitivity of the system increased by in-creasing the angle of diaphragm ,adopting the low friction cylinder ,the precision electric proportional valve and the high precision linear displacement sensor .Confirmed by the practical production applica-tion ,the tension closed-loop control system has more accurate precision and better dynamic perform-ance compared with the direct control system by the tension sensor and the indirect control system by the magnetic clutch ,which improves the quality of the two-way stretch polyester film .关键词
