The paper analyzes the procreant cause of the web tension and sets up the dynamic torque equation of the unloading scroll according to the research of the rewinder's scroll tension control.
本文通过对复卷机退纸卷张力控制进行探讨分析了张力产生的原因,建立退纸卷的动态转矩平衡方程,根据卷径和线速度大小的变化,调速装置通过组态完成卷径计算和电枢电流给定计算,并对其动态过程进行电流补偿,保持纸幅张力大小不变。
During the rewind machine's work,the rotate speed of paper roll which reel out paper has been accelerated.
复卷机工作时,放纸卷做加速旋转运动,文中以系统运动方程为依据,并以A级瓦楞纸的相关指标为例,通过计算,讨论了放纸辊转动惯量对张力控制的影响。
At the same time ,the effect of state-of-the-art reeler on upgrading reeling quality,optimizing reel structure,removing defects of paper,decreasing paper loss and increasing whole production efficiency of paper machine and after finishing is dis-cussed in detail.
同时,详细地阐述了现代卷纸机对提高卷取质量、优化纸卷结构、消除卷纸纸病、减少纸张损失以及提高纸机和后加工整体生产效率等的影响。
