張力控制(zhi)器在凹印設備(bei)制(zhi)造業的(de)運用

1.凹印(yin)機(ji)料(liao)卷(juan)(juan)在收、放卷(juan)(juan)過程中(zhong)，升陽興(xing)張(zhang)(zhang)力(li)(li)控制器報價，收卷(juan)(juan)和放卷(juan)(juan)直(zhi)(zhi)徑是(shi)(shi)不斷變(bian)化(hua)(hua)的(de)(de)，直(zhi)(zhi)徑的(de)(de)變(bian)化(hua)(hua)必須會引起料(liao)帶(dai)張(zhang)(zhang)力(li)(li)的(de)(de)變(bian)化(hua)(hua)。放卷(juan)(juan)在制動力(li)(li)矩不變(bian)的(de)(de)情況下，直(zhi)(zhi)徑減少(shao)(shao)，張(zhang)(zhang)力(li)(li)將(jiang)隨之(zhi)增(zeng)大。而(er)收卷(juan)(juan)則相反，如果收卷(juan)(juan)力(li)(li)矩不變(bian)時，隨著收卷(juan)(juan)直(zhi)(zhi)徑增(zeng)大，張(zhang)(zhang)力(li)(li)將(jiang)減少(shao)(shao)。這是(shi)(shi)凹印(yin)機(ji)的(de)(de)固有(you)特性所決定的(de)(de)，也是(shi)(shi)引起料(liao)帶(dai)張(zhang)(zhang)力(li)(li)變(bian)化(hua)(hua)的(de)(de)主要因素(su)之(zhi)一(yi)。

2.料帶內在(zai)材(cai)質的(de)不(bu)均勻性(xing)。如材(cai)料彈性(xing)模量的(de)波動，材(cai)料厚(hou)度沿寬度、長度方向(xiang)變化等，料卷的(de)質量偏心，以及生產環境(jing)溫度、濕(shi)度變化，都會對張力(li)控制器整機(ji)的(de)張力(li)波動帶來微妙的(de)影響(xiang)。

在工控(kong)行(xing)業，在一些(xie)帶狀和線狀類的(de)(de)(de)(de)產品，經常需要(yao)(yao)控(kong)制(zhi)(zhi)張力(li)(li)(li)來(lai)達到(dao)(dao)生產要(yao)(yao)求，張力(li)(li)(li)控(kong)制(zhi)(zhi)器(qi)(qi)就是控(kong)制(zhi)(zhi)這類張力(li)(li)(li)的(de)(de)(de)(de)一種儀表，寧(ning)化縣(xian)升(sheng)陽興張力(li)(li)(li)控(kong)制(zhi)(zhi)器(qi)(qi)，張力(li)(li)(li)控(kong)制(zhi)(zhi)器(qi)(qi)是一種由單片(pian)機(ji)或者一些(xie)嵌入(ru)(ru)式(shi)器(qi)(qi)件及外(wai)圍(wei)(wei)電路開發而(er)成(cheng)的(de)(de)(de)(de)系統，是一種控(kong)制(zhi)(zhi)儀表，它(ta)可以直(zhi)接(jie)設定要(yao)(yao)求控(kong)制(zhi)(zhi)的(de)(de)(de)(de)張力(li)(li)(li)值，然(ran)后直(zhi)接(jie)輸(shu)入(ru)(ru)張力(li)(li)(li)傳感器(qi)(qi)的(de)(de)(de)(de)信號（一般為毫伏(fu)級別(bie)）作為張力(li)(li)(li)反(fan)饋值，通(tong)過比較得出(chu)偏(pian)(pian)差后，輸(shu)入(ru)(ru)到(dao)(dao)PID等控(kong)制(zhi)(zhi)器(qi)(qi)進行(xing)處(chu)理，輸(shu)出(chu)給外(wai)圍(wei)(wei)執行(xing)機(ji)構去控(kong)制(zhi)(zhi)，終(zhong)達到(dao)(dao)偏(pian)(pian)差小，系統響應快的(de)(de)(de)(de)目的(de)(de)(de)(de)。
