摘　要:
張力控制是凹印機(jī)整機(jī)控制的核心。印刷過程中，張力變化范圍小，套印精度就容易控制。為了對凹印機(jī)張力控制的主要影響因素進(jìn)行正確分析，在考慮料卷軸芯結(jié)構(gòu)形式和重量分布的情況下，推導(dǎo)出凹印機(jī)放卷過程中的新的張力計算公式。在對我國凹印機(jī)幾種張力控制的類型進(jìn)行介紹的基礎(chǔ)上，對張力傳感器檢測、浮動輥檢測、浮動輥／反饋復(fù)合式檢測等幾種張力控制方式作了介紹。[著者文摘]
The Tension Control and Caculation of The Tension on Gravure PressLIU Fei Foshan Feiyou Automation Technology Co. Ltd, Foshan 528311, ChinaAbstract:
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.[著者文摘]
