捻(nian)線機(ji)(ji)是將(jiang)(jiang)多股細紗捻(nian)成一股的紡織(zhi)(zhi)機(ji)(ji)械設(she)備。作用是將(jiang)(jiang)紗或并合后股紗制品(pin)(pin)加工成線型(xing)制品(pin)(pin)、供織(zhi)(zhi)造(zao)和針織(zhi)(zhi)用線。

捻線機的分類

       1）環錠捻線機

        從(cong)筒子上引出的合股紗，經導(dao)紗桿和橫動導(dao)紗器從(cong)導(dao)紗羅拉輸(shu)出，通過導(dao)紗鉤和鋼(gang)絲圈(quan)繞于筒管上。

        當錠子帶動(dong)(dong)筒管一起回(hui)轉時，紗線拖動(dong)(dong)鋼絲圈在環狀鋼領上回(hui)轉，對紗線進行加捻。

        筒(tong)(tong)(tong)子(zi)(zi)(zi)(zi)紗(sha)(sha)架上的筒(tong)(tong)(tong)子(zi)(zi)(zi)(zi)大都(dou)是以橫(heng)臥(wo)形式(shi)活套在插錠上，合(he)股紗(sha)(sha)自側面拖(tuo)動(dong)筒(tong)(tong)(tong)子(zi)(zi)(zi)(zi)回轉而(er)退繞。并(bing)捻聯合(he)機(ji)是用單(dan)紗(sha)(sha)筒(tong)(tong)(tong)子(zi)(zi)(zi)(zi)喂(wei)入，為減(jian)少單(dan)紗(sha)(sha)退繞時張力過大而(er)引起斷頭，采用錐形筒(tong)(tong)(tong)子(zi)(zi)(zi)(zi)緊套在插錠上，單(dan)紗(sha)(sha)由各自的筒(tong)(tong)(tong)子(zi)(zi)(zi)(zi)端軸向(xiang)引出，在喂(wei)給紗(sha)(sha)架部分實現并(bing)合(he)。并(bing)捻聯合(he)機(ji)可省(sheng)除并(bing)紗(sha)(sha)工序(xu)，一般只適(shi)于紡品質要求不高的雙(shuang)股線。

      2）翼錠捻線機

       以錠(ding)(ding)翼(yi)為(wei)主要加捻(nian)機(ji)件。 除(chu)喂(wei)紗部分外(wai)，其余機(ji)構都和吊錠(ding)(ding)式翼(yi)錠(ding)(ding)細紗機(ji)相似，常(chang)用于黃麻的捻(nian)線(xian)。

      3）倍捻捻線機

       以倍捻(nian)(nian)錠子為主要(yao)加捻(nian)(nian)機(ji)件，每一回(hui)轉能(neng)對合股紗線加兩個捻(nian)(nian)回(hui)。

       倍捻(nian)錠子有立(li)式、臥式和斜式三種，以立(li)式為多。它由錠桿、錠盤(pan)和儲(chu)紗盤(pan)等回轉部(bu)分和盛紗罐、空心錠管等不動部(bu)分組成(cheng)。

       不動(dong)(dong)部分(fen)套在回轉(zhuan)部分(fen)外面(mian)，其間用(yong)滾動(dong)(dong)軸承聯系。錠盤(pan)由龍帶或錠帶傳(chuan)動(dong)(dong)，帶動(dong)(dong)儲紗盤(pan)一起回轉(zhuan)。為確保不動(dong)(dong)部分(fen)不受回轉(zhuan)部分(fen)影響，一般都裝有盛紗罐(guan)的制(zhi)(zhi)動(dong)(dong)裝置。制(zhi)(zhi)動(dong)(dong)方式有磁力制(zhi)(zhi)動(dong)(dong)、重力制(zhi)(zhi)動(dong)(dong)和機械制(zhi)(zhi)動(dong)(dong)三種。
