凹印机印刷过程中的张力计算与张力控制

The Tension Control and Caculation of The Tension on Gravure Press

张力控制是凹印机整机控制的核心。印刷过程中,张力变化范围小,套印精度就容易控制。为了对凹印机张力控制的主要影响因素进行正确分析,在考虑料卷轴芯结构形式和重量分布的情况下,推导出凹印机放卷过程中的新的张力计算公式。在对我国凹印机几种张力控制的类型进行介绍的基础上,对张力传感器检测、浮动辊检测、浮动辊/反馈复合式检测等几种张力控制方式作了介绍。

Tension control is cave print, the whole machine control of core. Printing process in tension variety the scope may be small, the set print accuracy easily controlled. For the sake of rightness cave print machine tension control of main impact factor carry on exactitude analysis, at consideration anticipate under the circumstance that the roller for scrolls structure form and weight distribute, deduce one cave print machine to input a process of new of tension calculation formula. At cave to our country, the foundation printed a few tension of machine, the type of control to carry on introduction up, spread a feeling machine examination, float roller examination and float roller/feedback compound type examination etc. to the tension several medium tension control the way made introduction.
