縫紉機的縫合原理是什么

縫(feng)(feng)紉機(ji)的(de)核心是線(xian)(xian)圈(quan)(quan)(quan)縫(feng)(feng)合系(xi)統(tong)，其(qi)(qi)線(xian)(xian)圈(quan)(quan)(quan)縫(feng)(feng)合方法與普通手(shou)工(gong)縫(feng)(feng)紉差異很(hen)大，在機(ji)針(zhen)(zhen)(zhen)上，針(zhen)(zhen)(zhen)眼就在尖頭的(de)后(hou)面(mian)(mian)，而不是在針(zhen)(zhen)(zhen)的(de)尾端。縫(feng)(feng)紉機(ji)只需將針(zhen)(zhen)(zhen)部分穿(chuan)(chuan)過織(zhi)物，針(zhen)(zhen)(zhen)固定在針(zhen)(zhen)(zhen)桿上，針(zhen)(zhen)(zhen)桿由電機(ji)通過一(yi)(yi)系(xi)列的(de)齒輪和凸輪牽引(yin)做上下運動。當針(zhen)(zhen)(zhen)的(de)尖端穿(chuan)(chuan)過織(zhi)物時(shi)，它在一(yi)(yi)面(mian)(mian)向(xiang)另一(yi)(yi)面(mian)(mian)拉出一(yi)(yi)個(ge)(ge)(ge)小線(xian)(xian)圈(quan)(quan)(quan)。織(zhi)物下面(mian)(mian)的(de)一(yi)(yi)個(ge)(ge)(ge)裝置(zhi)會抓住(zhu)這個(ge)(ge)(ge)線(xian)(xian)圈(quan)(quan)(quan)，然后(hou)將其(qi)(qi)包住(zhu)另一(yi)(yi)根線(xian)(xian)或者同一(yi)(yi)根線(xian)(xian)的(de)另一(yi)(yi)個(ge)(ge)(ge)線(xian)(xian)圈(quan)(quan)(quan)。

最簡(jian)單的(de)(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)縫(feng)合是鏈(lian)式(shi)縫(feng)合，若要縫(feng)出鏈(lian)式(shi)縫(feng)合，縫(feng)紉機會(hui)在線(xian)(xian)(xian)的(de)(de)后面(mian)用相同長(chang)度(du)的(de)(de)線(xian)(xian)(xian)打環。織(zhi)物(wu)位(wei)于針(zhen)下面(mian)的(de)(de)一(yi)(yi)塊金(jin)屬板上(shang)，用壓腳固(gu)定。每次(ci)縫(feng)合開始時，針(zhen)穿過(guo)織(zhi)物(wu)拉出一(yi)(yi)個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)，而(er)一(yi)(yi)個做(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)裝(zhuang)置(zhi)(zhi)在針(zhen)拉出前抓住線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)，該裝(zhuang)置(zhi)(zhi)與(yu)針(zhen)同步運動。一(yi)(yi)旦針(zhen)拉出織(zhi)物(wu)，送布牙裝(zhuang)置(zhi)(zhi)就會(hui)將織(zhi)物(wu)往前拉。當針(zhen)再次(ci)穿過(guo)織(zhi)物(wu)時，新的(de)(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)將直(zhi)接穿過(guo)前一(yi)(yi)個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)中(zhong)間。做(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)裝(zhuang)置(zhi)(zhi)會(hui)再次(ci)抓住線(xian)(xian)(xian)，圍繞(rao)下一(yi)(yi)個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)做(zuo)線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)。這(zhe)樣(yang)，每個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)都會(hui)把下一(yi)(yi)個線(xian)(xian)(xian)圈(quan)(quan)(quan)(quan)固(gu)定到位(wei)。

鏈(lian)式縫(feng)合的主(zhu)要優點是可以(yi)縫(feng)得非常快，但是，它(ta)不是特別(bie)地結實(shi)，如果線的一端松開(kai)，可能整個縫(feng)紉(ren)會全(quan)部松脫。大多數縫(feng)紉(ren)機使用一種(zhong)更結實(shi)的縫(feng)線，叫做鎖縫(feng)。

鎖縫裝置最重(zhong)要(yao)的(de)元件是(shi)擺梭(suo)鉤和線(xian)(xian)(xian)軸(zhou)組件。線(xian)(xian)(xian)軸(zhou)就是(shi)放(fang)在(zai)(zai)織(zhi)物(wu)(wu)下面的(de)一(yi)(yi)卷線(xian)(xian)(xian)。它位于(yu)擺梭(suo)的(de)中(zhong)央，后(hou)者(zhe)在(zai)(zai)電機(ji)的(de)帶動(dong)下旋轉，與(yu)針(zhen)的(de)運動(dong)同(tong)步。與(yu)鏈式縫合(he)(he)相(xiang)同(tong)，針(zhen)穿(chuan)過織(zhi)物(wu)(wu)拉出(chu)一(yi)(yi)個線(xian)(xian)(xian)圈，在(zai)(zai)送布牙向前移(yi)動(dong)織(zhi)物(wu)(wu)的(de)同(tong)時(shi)它再次升起(qi)(qi)，然后(hou)將(jiang)(jiang)另(ling)外一(yi)(yi)個線(xian)(xian)(xian)圈套入(ru)。不(bu)(bu)過，這(zhe)種(zhong)縫合(he)(he)機(ji)制不(bu)(bu)是(shi)將(jiang)(jiang)不(bu)(bu)同(tong)的(de)線(xian)(xian)(xian)圈連接在(zai)(zai)一(yi)(yi)起(qi)(qi)，而(er)是(shi)將(jiang)(jiang)它們與(yu)從線(xian)(xian)(xian)軸(zhou)上松開的(de)另(ling)一(yi)(yi)段(duan)線(xian)(xian)(xian)連接起(qi)(qi)來。

縫紉機的組成部件有哪些

一(yi)般縫紉(ren)機(ji)都由機(ji)頭、機(ji)座(zuo)、傳(chuan)動和(he)附件(jian)四部分組成。機(ji)頭是(shi)縫紉(ren)機(ji)的主要部分。它由刺(ci)料、鉤(gou)線、挑線、送料四個機(ji)構和(he)繞線、壓料、落牙等輔助機(ji)構組成，各(ge)機(ji)構的運動合理地配合，循環工作(zuo)，把縫料縫合起(qi)來。

機(ji)(ji)(ji)(ji)座分為(wei)臺(tai)板和(he)(he)機(ji)(ji)(ji)(ji)箱(xiang)(xiang)兩種(zhong)形式。臺(tai)板式機(ji)(ji)(ji)(ji)座的(de)臺(tai)板起著(zhu)支承機(ji)(ji)(ji)(ji)頭(tou)的(de)作(zuo)用，縫紉(ren)操作(zuo)時當作(zuo)工作(zuo)臺(tai)用。臺(tai)板有多種(zhong)式樣(yang)，有一斗(dou)或多斗(dou)摺(zhe)藏(zang)(zang)式、柜(ju)式、寫(xie)字臺(tai)式等。機(ji)(ji)(ji)(ji)箱(xiang)(xiang)式機(ji)(ji)(ji)(ji)座的(de)機(ji)(ji)(ji)(ji)箱(xiang)(xiang)起著(zhu)支承和(he)(he)貯藏(zang)(zang)機(ji)(ji)(ji)(ji)頭(tou)的(de)作(zuo)用，使縫紉(ren)機(ji)(ji)(ji)(ji)便(bian)于攜帶和(he)(he)保管(guan)。

縫紉機的傳動(dong)(dong)部分由機(ji)(ji)架、手搖器(qi)或(huo)電動(dong)(dong)機(ji)(ji)等部件構成。機(ji)(ji)架是(shi)機(ji)(ji)器(qi)的支柱(zhu)，支承(cheng)著臺板和腳(jiao)踏(ta)板。使(shi)用時(shi)操作(zuo)者踩動(dong)(dong)腳(jiao)踏(ta)板，通(tong)過曲柄帶動(dong)(dong)皮帶輪的旋轉，又通(tong)過皮帶帶動(dong)(dong)機(ji)(ji)頭旋轉。手搖器(qi)或(huo)電動(dong)(dong)機(ji)(ji)多數直接裝在機(ji)(ji)頭上。

縫紉機的附件(jian)包括機針、梭心、螺(luo)絲刀、油壺等。
