一、大圓機是做什么的

在紡織機械中，大(da)圓(yuan)機是(shi)(shi)比較(jiao)常見的(de)，是(shi)(shi)工廠經(jing)常選擇的(de)工業紡織設備(bei)之一，那么你知道大(da)圓(yuan)機是(shi)(shi)用(yong)來做什么的(de)嗎？

大圓機是做針織布用的機械設備，就是用來生產平常穿的內衣或運動服、汗衫(shan)(shan)T恤衫(shan)(shan)等(deng)半成品布料(liao)用的，產品還需要染色后處(chu)理后才(cai)可以做衣服。

二、大圓針織機工作原理是什么

原理：馬(ma)達經皮(pi)帶(dai)(dai)(dai)和(he)皮(pi)帶(dai)(dai)(dai)輪(lun)(lun)(lun)傳(chuan)動(dong)(dong)(dong)小齒(chi)(chi)輪(lun)(lun)(lun)，后(hou)者驅(qu)動(dong)(dong)(dong)固(gu)裝(zhuang)有(you)針(zhen)筒的(de)大(da)盤齒(chi)(chi)輪(lun)(lun)(lun)。機架上方(fang)(fang)與(yu)大(da)盤齒(chi)(chi)輪(lun)(lun)(lun)固(gu)結，下方(fang)(fang)坐落在固(gu)定傘(san)(san)齒(chi)(chi)輪(lun)(lun)(lun)上。當大(da)盤齒(chi)(chi)輪(lun)(lun)(lun)轉(zhuan)動(dong)(dong)(dong)時，帶(dai)(dai)(dai)動(dong)(dong)(dong)整個牽(qian)拉卷(juan)取機構(gou)與(yu)針(zhen)筒同(tong)步(bu)回轉(zhuan)。此(ci)時，與(yu)傘(san)(san)齒(chi)(chi)輪(lun)(lun)(lun)8嚙合(he)的(de)傘(san)(san)齒(chi)(chi)輪(lun)(lun)(lun)轉(zhuan)動(dong)(dong)(dong)，經變速(su)齒(chi)(chi)輪(lun)(lun)(lun)箱變速(su)后(hou)，驅(qu)動(dong)(dong)(dong)橫(heng)(heng)軸(zhou)(zhou)(zhou)轉(zhuan)動(dong)(dong)(dong)。固(gu)結在橫(heng)(heng)軸(zhou)(zhou)(zhou)一(yi)側的(de)鏈(lian)輪(lun)(lun)(lun)經鏈(lian)條(tiao)(tiao)傳(chuan)動(dong)(dong)(dong)鏈(lian)輪(lun)(lun)(lun)，從(cong)(cong)(cong)而(er)使(shi)與(yu)鏈(lian)輪(lun)(lun)(lun)同(tong)軸(zhou)(zhou)(zhou)的(de)牽(qian)拉輥轉(zhuan)動(dong)(dong)(dong)進行(xing)(xing)牽(qian)拉。固(gu)結在橫(heng)(heng)軸(zhou)(zhou)(zhou)另一(yi)側的(de)鏈(lian)輪(lun)(lun)(lun)經鏈(lian)條(tiao)(tiao)傳(chuan)動(dong)(dong)(dong)鏈(lian)輪(lun)(lun)(lun)，從(cong)(cong)(cong)而(er)使(shi)與(yu)鏈(lian)輪(lun)(lun)(lun)同(tong)軸(zhou)(zhou)(zhou)的(de)主動(dong)(dong)(dong)皮(pi)帶(dai)(dai)(dai)輪(lun)(lun)(lun)轉(zhuan)動(dong)(dong)(dong)。皮(pi)帶(dai)(dai)(dai)輪(lun)(lun)(lun)經皮(pi)帶(dai)(dai)(dai)傳(chuan)動(dong)(dong)(dong)從(cong)(cong)(cong)動(dong)(dong)(dong)皮(pi)帶(dai)(dai)(dai)輪(lun)(lun)(lun)，從(cong)(cong)(cong)而(er)驅(qu)動(dong)(dong)(dong)與(yu)皮(pi)帶(dai)(dai)(dai)輪(lun)(lun)(lun)同(tong)軸(zhou)(zhou)(zhou)的(de)卷(juan)取輥進行(xing)(xing)卷(juan)布。

1、應用選針(zhen)機構(gou)使織(zhi)針(zhen)按預先(xian)安排的程(cheng)序投入工作，以編織(zhi)提花(hua)針(zhen)織(zhi)物。

2、應用梳毛機(ji)構把(ba)散纖維喂入織針，以(yi)編(bian)織長毛絨針織物。

3、應(ying)用襯(chen)經(jing)襯(chen)緯(wei)裝(zhuang)置(zhi)，以編(bian)織(zhi)襯(chen)經(jing)襯(chen)緯(wei)針織(zhi)物。

針織(zhi)機的(de)品(pin)種繁多，已(yi)超過350種。隨著化(hua)學(xue)纖維新(xin)品(pin)種和(he)后整(zheng)理工藝的(de)發(fa)展，提高(gao)了(le)針織(zhi)物挺刮、免燙(tang)和(he)耐磨(mo)等特性。拉絨(rong)、磨(mo)絨(rong)、剪毛(mao)、軋花和(he)褶(zhe)裥等整(zheng)理技術的(de)應用，使針織(zhi)品(pin)的(de)品(pin)種更為擴大(da)。

三、大圓機的工作過程

1、成(cheng)圈(quan)(quan)過(guo)(guo)程紗線(xian)構(gou)成(cheng)線(xian)圈(quan)(quan)，經過(guo)(guo)縱向串套(tao)和橫向連接便成(cheng)為針(zhen)(zhen)織物。所以成(cheng)圈(quan)(quan)是針(zhen)(zhen)織的基本(ben)工藝。成(cheng)圈(quan)(quan)過(guo)(guo)程可按順序(xu)分解成(cheng)下(xia)列幾(ji)個階段：退圈(quan)(quan)——把(ba)剛(gang)形成(cheng)的線(xian)圈(quan)(quan)（稱舊(jiu)線(xian)圈(quan)(quan)）從針(zhen)(zhen)鉤(gou)移至針(zhen)(zhen)桿(gan)；墊紗——把(ba)紗線(xian)喂到織針(zhen)(zhen)上；彎(wan)紗——把(ba)紗線(xian)彎(wan)曲成(cheng)線(xian)圈(quan)(quan)的形狀；帶紗——把(ba)新墊上的紗線(xian)或剛(gang)彎(wan)成(cheng)的線(xian)圈(quan)(quan)移至針(zhen)(zhen)鉤(gou)內；閉口——封閉織針(zhen)(zhen)針(zhen)(zhen)口；套(tao)圈(quan)(quan)——把(ba)舊(jiu)線(xian)圈(quan)(quan)套(tao)到針(zhen)(zhen)口閉合的針(zhen)(zhen)鉤(gou)上。

2、連圈(quan)(quan)(quan)(quan)——新紗(sha)(sha)線(xian)或新線(xian)圈(quan)(quan)(quan)(quan)與(yu)舊線(xian)圈(quan)(quan)(quan)(quan)在針鉤內外(wai)相(xiang)遇；脫圈(quan)(quan)(quan)(quan)——舊線(xian)圈(quan)(quan)(quan)(quan)從針鉤上(shang)脫下套在新線(xian)圈(quan)(quan)(quan)(quan)上(shang)；成(cheng)(cheng)圈(quan)(quan)(quan)(quan)——使紗(sha)(sha)線(xian)形成(cheng)(cheng)一(yi)只(zhi)封閉的和(he)規定(ding)大小的新線(xian)圈(quan)(quan)(quan)(quan)；牽拉——把新線(xian)圈(quan)(quan)(quan)(quan)拉離成(cheng)(cheng)圈(quan)(quan)(quan)(quan)區域。這只(zhi)新線(xian)圈(quan)(quan)(quan)(quan)在下一(yi)成(cheng)(cheng)圈(quan)(quan)(quan)(quan)周期中(zhong)即成(cheng)(cheng)為舊線(xian)圈(quan)(quan)(quan)(quan)。成(cheng)(cheng)圈(quan)(quan)(quan)(quan)過程(cheng)(cheng)(cheng)有(you)針織(zhi)(zhi)法和(he)編(bian)結法兩(liang)類。在針織(zhi)(zhi)法成(cheng)(cheng)圈(quan)(quan)(quan)(quan)過程(cheng)(cheng)(cheng)中(zhong)，成(cheng)(cheng)圈(quan)(quan)(quan)(quan)各(ge)階(jie)段(duan)按上(shang)述順序進行。在編(bian)結法成(cheng)(cheng)圈(quan)(quan)(quan)(quan)過程(cheng)(cheng)(cheng)中(zhong)，彎(wan)紗(sha)(sha)始于脫圈(quan)(quan)(quan)(quan)，并(bing)與(yu)成(cheng)(cheng)圈(quan)(quan)(quan)(quan)階(jie)段(duan)同時進行。在有(you)的針織(zhi)(zhi)機上(shang)各(ge)只(zhi)織(zhi)(zhi)針依次順序完成(cheng)(cheng)成(cheng)(cheng)圈(quan)(quan)(quan)(quan)過程(cheng)(cheng)(cheng)；也有(you)一(yi)些針織(zhi)(zhi)機的成(cheng)(cheng)圈(quan)(quan)(quan)(quan)過程(cheng)(cheng)(cheng)各(ge)只(zhi)織(zhi)(zhi)針整列地同時進行。
