高速在线涂布机传动控制系统的优化从四个方面入手:为了减少涂布机引纸时张力的大幅波动,对机群的速度链作出相应优化;为了抑制上涂时背辊前后纸幅剧烈晃动,对涂布背辊传动电机进行预控力矩提升,同时对舒展辊、导纸辊及烘缸群传动电机进行速度提升;为了防止纸幅断头时引起的张力波动,对烘缸群传动电机的预控力矩作出提升;为了便于引纸,对舒展辊、导纸辊传动电机的滑差补偿(软特性)模式作出优化。综上优化措施的实施,提高了传动系统的稳定性和控制精度。
The optimization of transmission control system of high-speed on-line coater starts from four aspects: In order to reduce the large fluctuation of tension when coiling machine leads, optimize the speed chain of the machine cluster; , The coating back roller drive motor pre-control torque to improve, at the same time on the roll, paper guide roller and dryer group drive motor speed increase; in order to prevent tension caused when the web breaks, on the dryer group drive motor Of the pre-control torque to improve; in order to facilitate the introduction of paper, the roll roll, paper guide roller slip motor compensation (soft features) mode to optimize. To sum up the implementation of optimization measures to improve the transmission system stability and control accuracy.
