張力控制是造紙、塑料、紡織工業(yè)等卷繞自動(dòng)化生產(chǎn)線中的關(guān)鍵技術(shù)。本文從墻紙生產(chǎn)過(guò)程的實(shí)際出發(fā)，研制了一套基于PC 張力控制系統(tǒng)。經(jīng)過(guò)實(shí)際生產(chǎn)運(yùn)行證明，該系統(tǒng)張力控制穩(wěn)定，實(shí)時(shí)性好，運(yùn)行可靠，實(shí)現(xiàn)了墻紙生產(chǎn)過(guò)程的最優(yōu)控制。
關(guān)鍵詞：PC ，線速度，張力控制，穩(wěn)定性
Abstract: The control system of tension has been a key technology for automatic assembly line of the wallpaper products , the plastics products and spinning. This paper discussed the control system of tension through the wallpaper-production regarding rea l i stic needs. The
design idea , schematic diagram design , major function and feature of the tension control system have been expounded in this paper. The control system of tension based on PC has been p r o v e d f a s t , r e l i a b l e a n d steady by realistic producing. This system has realistic signif icat ion to reconstructing tradi tional machining industrialism and it can realize the optimum control for t he p r o c e s s o f wal l p a p e r p r od u c t i o n p r e f e r a bl y.
Key words: PC , line-velocity , tension control，reliability
