摘要:通过对纸巾纸机设备中的卷纸机、退纸机、复卷机等收放卷过程进行建模和运动学分析,导出了纸巾纸机各收放卷过程的数学公式和曲线图,讨论了收放卷过程纸卷卷径变化对上述设备相应结构的运动控制要求,指出应根据各生产设备功能的不同对收放卷辅助设备进行差异化控制,从而保证纸卷收放卷过程可靠稳定地进行,实现纸幅的恒张力控制。

Abstract:By modeling and kinematic analyzing the winding and unwinding process of the paper roll in the winder, unwinder and rewinder of tissue paper machine, their mathematical formulas and graphs were derived, and the effect of the variation of the roll diameter in winding and unwinding processes on the kinematic control of winder, unwinder and rewinder was discussed. It was concluded that it is necessary to differently control the winder or unwinder device according to its individual function so as to keep a steady winding or unwinding process and to ensure a constant web tension．
