青島(dao)(dao)某機械制(zhi)造(zao)有(you)限(xian)公(gong)司位于青島(dao)(dao)市膠州灣(wan)西岸，與青島(dao)(dao)經濟技術開發區毗鄰，是(shi)目前國內(nei)專業(ye)生產,,,,,等紡織機械的主(zhu)要生(sheng)產(chan)廠家。該公(gong)司給鹽(yan)城建湖亞華紡織廠改造的喂(wei)棉箱(xiang)傳動機構采用我們普傳PI9100A高性能電流矢量變頻器(qi)。
喂(wei)棉箱作用(yong)是將經過均勻開(kai)松(song)、混合后(hou)的纖維形成均勻的筵棉層喂(wei)入梳棉機，確保(bao)梳棉機的連續(xu)均勻供棉，實現清梳聯(lian)工(gong)序連續(xu)化。該喂(wei)棉箱主要特點就是喂(wei)棉羅拉采用(yong)變(bian)頻器(qi)調速(su)，有(you)效改善棉條(tiao)均勻度及重量不勻率(lv)。
該設備有錫(xi)林電(dian)機(ji)(ji)(ji)(ji)、開松棍電(dian)機(ji)(ji)(ji)(ji)、 梳棉(mian)(mian)機(ji)(ji)(ji)(ji)喂棉(mian)(mian)電(dian)機(ji)(ji)(ji)(ji)、棉(mian)(mian)箱風(feng)機(ji)(ji)(ji)(ji)和棉(mian)(mian)箱落棉(mian)(mian)電(dian)機(ji)(ji)(ji)(ji)等傳(chuan)動(dong)機(ji)(ji)(ji)(ji)構組成。錫(xi)林電(dian)機(ji)(ji)(ji)(ji)、開松棍電(dian)機(ji)(ji)(ji)(ji)和棉(mian)(mian)箱電(dian)機(ji)(ji)(ji)(ji)均為交(jiao)流異(yi)步(bu)電(dian)機(ji)(ji)(ji)(ji)傳(chuan)動(dong)，其中梳棉(mian)(mian)機(ji)(ji)(ji)(ji)喂棉(mian)(mian)電(dian)機(ji)(ji)(ji)(ji)0.75kW和棉(mian)(mian)箱落棉(mian)(mian)電(dian)機(ji)(ji)(ji)(ji)0.2kw交(jiao)流異(yi)步(bu)電(dian)機(ji)(ji)(ji)(ji)，用普傳(chuan)PI9100A變頻器調速。
全機(ji)采(cai)用PLC控制(zhi)(zhi)：控制(zhi)(zhi)道夫和給棉(mian)羅拉（刺(ci)輥）傳動(dong)(dong)電(dian)機(ji)的(de)速(su)度和比例(li)跟蹤運(yun)轉(zhuan)；控制(zhi)(zhi)圈條(tiao)(tiao)電(dian)機(ji)的(de)運(yun)轉(zhuan)并確保其與道夫同步運(yun)轉(zhuan)；控制(zhi)(zhi)滿(man)筒(tong)(tong)(tong)(tong)后自(zi)動(dong)(dong)換(huan)(huan)筒(tong)(tong)(tong)(tong)，換(huan)(huan)筒(tong)(tong)(tong)(tong)過程如下，當計長達到設定(ding)值時(shi)，PLC控制(zhi)(zhi)車速(su)降(jiang)低，并發出換(huan)(huan)筒(tong)(tong)(tong)(tong)信號，電(dian)磁(ci)閥控制(zhi)(zhi)機(ji)械機(ji)構(gou)切斷(duan)棉(mian)條(tiao)(tiao)并夾(jia)住上端棉(mian)條(tiao)(tiao)，伺(si)服(fu)電(dian)機(ji)轉(zhuan)動(dong)(dong)棉(mian)條(tiao)(tiao)筒(tong)(tong)(tong)(tong)底盤(pan)，把(ba)空筒(tong)(tong)(tong)(tong)放在(zai)棉(mian)條(tiao)(tiao)筒(tong)(tong)(tong)(tong)固定(ding)位(wei)置，并把(ba)滿(man)筒(tong)(tong)(tong)(tong)推出，夾(jia)住棉(mian)條(tiao)(tiao)機(ji)構(gou)放開棉(mian)條(tiao)(tiao)，升速(su)至(zhi)正(zheng)常生產(chan)速(su)度，換(huan)(huan)筒(tong)(tong)(tong)(tong)結束。
機上(shang)設有(you)觸摸屏設定并(bing)顯示落棉(mian)頻率、開松轉(zhuan)速(su)、棉(mian)箱實際(ji)壓(ya)力、基準壓(ya)力工藝參數，面板上(shang)還安裝有(you)反轉(zhuan)點動開關及故障(zhang)報警指示燈。
通過檢測喂入(ru)棉(mian)層厚度(du)(du)和(he)輸出棉(mian)條重量(liang)經數據計算處理(li)后控制給棉(mian)羅拉轉速(su)、實(shi)現棉(mian)條的(de)勻整，改善條干均勻度(du)(du)，棉(mian)條重量(liang)內不勻可(ke)達1.8%左右。
接(jie)線(xian)要求：
1、主(zhu)接線端子，RST接交流(liu)380V，UVW接電(dian)動機輸入(ru)線。
2、控(kong)制端子(zi)，DI1/DI2接(jie)啟(qi)停控(kong)制正(zheng)反轉信號，COM接(jie)控(kong)制信號公共點；TA1/TC1接(jie)故障報警電(dian)路(lu)；AI1/GND接(jie)頻率控(kong)制模擬量0-10V。
