捻線(xian)機是(shi)將多股細紗(sha)捻成一(yi)股的紡(fang)織機械設備(bei)。作用是(shi)將紗(sha)或并(bing)合后(hou)股紗(sha)制(zhi)品加工成線(xian)型制(zhi)品、供(gong)織造和針織用線(xian)。

捻線機的分類

       1）環錠捻線機

        從(cong)筒子上引出(chu)的合(he)股紗，經導紗桿(gan)和橫動(dong)導紗器從(cong)導紗羅拉輸出(chu)，通過(guo)導紗鉤和鋼絲(si)圈繞(rao)于筒管上。

        當錠子帶動筒管一起回轉(zhuan)時，紗(sha)線拖動鋼(gang)絲圈在環狀(zhuang)鋼(gang)領(ling)上回轉(zhuan)，對紗(sha)線進行(xing)加捻。

        筒(tong)(tong)子(zi)(zi)紗(sha)架上的(de)(de)筒(tong)(tong)子(zi)(zi)大(da)(da)都是(shi)以橫臥形式活(huo)套(tao)在(zai)插錠(ding)上，合(he)股紗(sha)自側面(mian)拖(tuo)動筒(tong)(tong)子(zi)(zi)回轉而(er)退繞。并捻(nian)聯合(he)機是(shi)用(yong)單(dan)(dan)紗(sha)筒(tong)(tong)子(zi)(zi)喂入，為減少單(dan)(dan)紗(sha)退繞時張力過大(da)(da)而(er)引起斷頭，采用(yong)錐形筒(tong)(tong)子(zi)(zi)緊(jin)套(tao)在(zai)插錠(ding)上，單(dan)(dan)紗(sha)由各自的(de)(de)筒(tong)(tong)子(zi)(zi)端軸向引出，在(zai)喂給紗(sha)架部分(fen)實現并合(he)。并捻(nian)聯合(he)機可(ke)省除并紗(sha)工序，一般只適于紡品(pin)質要(yao)求不高的(de)(de)雙(shuang)股線。

      2）翼錠捻線機

       以(yi)錠(ding)(ding)翼(yi)為(wei)主要加捻(nian)機(ji)件(jian)。 除喂紗(sha)部分(fen)外，其余機(ji)構(gou)都和吊錠(ding)(ding)式翼(yi)錠(ding)(ding)細紗(sha)機(ji)相似，常用(yong)于黃麻的捻(nian)線。

      3）倍捻捻線機

       以倍捻(nian)錠(ding)子為主要加捻(nian)機件(jian)，每一回(hui)轉(zhuan)能對合股紗線加兩個捻(nian)回(hui)。

       倍捻錠子(zi)有(you)立式(shi)、臥(wo)式(shi)和(he)斜式(shi)三種，以立式(shi)為多。它由錠桿、錠盤(pan)(pan)和(he)儲紗盤(pan)(pan)等回轉部(bu)分(fen)和(he)盛紗罐、空心錠管(guan)等不動(dong)部(bu)分(fen)組(zu)成。

       不(bu)動(dong)(dong)(dong)(dong)(dong)部(bu)分套在回轉(zhuan)(zhuan)部(bu)分外面，其間(jian)用滾動(dong)(dong)(dong)(dong)(dong)軸承聯系。錠(ding)盤(pan)由龍(long)帶(dai)或錠(ding)帶(dai)傳動(dong)(dong)(dong)(dong)(dong)，帶(dai)動(dong)(dong)(dong)(dong)(dong)儲紗(sha)(sha)盤(pan)一(yi)起回轉(zhuan)(zhuan)。為確保不(bu)動(dong)(dong)(dong)(dong)(dong)部(bu)分不(bu)受(shou)回轉(zhuan)(zhuan)部(bu)分影響，一(yi)般都裝有盛紗(sha)(sha)罐的制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)裝置。制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)方式(shi)有磁力(li)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)、重(zhong)力(li)制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)和(he)機械制(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)三種。
