捻線機是(shi)將多股(gu)(gu)細紗(sha)(sha)捻成一股(gu)(gu)的(de)紡織(zhi)機械(xie)設(she)備。作用是(shi)將紗(sha)(sha)或并合后(hou)股(gu)(gu)紗(sha)(sha)制品加(jia)工成線型制品、供織(zhi)造和針織(zhi)用線。

捻線機的分類

       1）環錠捻線機

        從筒(tong)子上引(yin)出的合股紗(sha)，經導紗(sha)桿(gan)和(he)橫動導紗(sha)器從導紗(sha)羅(luo)拉輸出，通過導紗(sha)鉤和(he)鋼絲圈繞于筒(tong)管上。

        當錠子帶動筒管一起回轉時，紗(sha)線拖(tuo)動鋼絲圈在環狀(zhuang)鋼領(ling)上回轉，對紗(sha)線進行加捻。

        筒(tong)(tong)(tong)(tong)子(zi)(zi)紗(sha)架(jia)上(shang)的(de)筒(tong)(tong)(tong)(tong)子(zi)(zi)大都(dou)是(shi)以橫臥形式(shi)活套在插錠上(shang)，合(he)(he)股紗(sha)自側面拖動(dong)筒(tong)(tong)(tong)(tong)子(zi)(zi)回(hui)轉而(er)退繞。并(bing)捻(nian)聯(lian)合(he)(he)機(ji)是(shi)用單(dan)(dan)紗(sha)筒(tong)(tong)(tong)(tong)子(zi)(zi)喂入(ru)，為減(jian)少單(dan)(dan)紗(sha)退繞時張力過大而(er)引(yin)起(qi)斷頭，采(cai)用錐形筒(tong)(tong)(tong)(tong)子(zi)(zi)緊套在插錠上(shang)，單(dan)(dan)紗(sha)由各(ge)自的(de)筒(tong)(tong)(tong)(tong)子(zi)(zi)端(duan)軸向引(yin)出，在喂給(gei)紗(sha)架(jia)部分實現并(bing)合(he)(he)。并(bing)捻(nian)聯(lian)合(he)(he)機(ji)可省除并(bing)紗(sha)工序，一般只適于(yu)紡(fang)品質要求不(bu)高的(de)雙股線(xian)。

      2）翼錠捻線機

       以(yi)錠翼(yi)為主要加捻(nian)機件。 除喂紗(sha)部分外，其(qi)余機構都和吊錠式翼(yi)錠細(xi)紗(sha)機相(xiang)似，常用于黃(huang)麻的捻(nian)線(xian)。

      3）倍捻捻線機

       以倍捻(nian)錠子為主(zhu)要加捻(nian)機(ji)件，每一回轉能對合股紗線(xian)加兩個捻(nian)回。

       倍捻錠(ding)(ding)子有立式、臥式和斜式三種，以立式為多。它(ta)由(you)錠(ding)(ding)桿(gan)、錠(ding)(ding)盤和儲紗盤等回轉部(bu)分(fen)和盛紗罐、空心錠(ding)(ding)管等不(bu)動部(bu)分(fen)組成。

       不動(dong)(dong)部(bu)(bu)分套在(zai)回轉(zhuan)部(bu)(bu)分外面，其間用滾動(dong)(dong)軸承聯(lian)系。錠盤由龍(long)帶(dai)或錠帶(dai)傳動(dong)(dong)，帶(dai)動(dong)(dong)儲紗盤一起回轉(zhuan)。為確保不動(dong)(dong)部(bu)(bu)分不受回轉(zhuan)部(bu)(bu)分影響，一般(ban)都裝有盛紗罐(guan)的制(zhi)動(dong)(dong)裝置。制(zhi)動(dong)(dong)方式有磁力(li)制(zhi)動(dong)(dong)、重(zhong)力(li)制(zhi)動(dong)(dong)和機械制(zhi)動(dong)(dong)三種。
