摘要:
针对双向拉伸聚酯薄膜生产中，纵向拉伸机入口及出口张力对薄膜拉伸质量具有重要影响，提出了一种运用摆辊张力进行调节的闭环控制方式.当摆辊位移时，直线位移传感器反馈信号产生波动，经与标准电压信号比较后得出的偏差值传递给变频器，然后变频器输出控制信号改变电机转速，以实现闭环控制.该系统通过增大膜片包角、采用低摩擦气缸、精密电气比例阀和高精度直线位移传感器等措施灵敏度得以提高.经实际生产应用验证，该闭环张力控制系统较张力传感器直接控制和磁粉离合器控制转矩间接控制，系统的控制精度更高、动态性能更好，对双向拉伸聚酯薄膜的纵向拉伸质量有显著提升.
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 frequency converter, and the motor speed was controlled by the signal from the frequency converter. Finally, the purpose of closedloop control was achieved. The sensitivity of the system increased by increasing 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 application, the tension closedloop control system has more accurate precision and better dynamic performance 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.
