一種縫紉機少鳥巢剪線機構及縫紉機的制作方法

本技(ji)術(shu)涉(she)及縫紉(ren)(ren)(ren)機(ji),特別是(shi)涉(she)及一(yi)種縫紉(ren)(ren)(ren)機(ji)少鳥巢剪(jian)線(xian)機(ji)構(gou)、以及包含有該(gai)縫紉(ren)(ren)(ren)機(ji)少鳥巢剪(jian)線(xian)機(ji)構(gou)的縫紉(ren)(ren)(ren)機(ji)。


背景技術:

1、在上次(ci)縫(feng)紉結束剪線(xian)后,機針的(de)(de)一(yi)側會殘留有一(yi)段一(yi)定長度(du)的(de)(de)面線(xian)線(xian)頭(tou),該(gai)面線(xian)線(xian)頭(tou)構(gou)成起(qi)針線(xian)頭(tou)。下次(ci)縫(feng)制起(qi)縫(feng)時,起(qi)針線(xian)頭(tou)極容易在縫(feng)制衣(yi)(yi)物(wu)(wu)(wu)上形(xing)成鳥(niao)巢(chao)(chao)狀線(xian)頭(tou),影響(xiang)整個衣(yi)(yi)物(wu)(wu)(wu)的(de)(de)質(zhi)量,也(ye)就影響(xiang)了(le)整個衣(yi)(yi)物(wu)(wu)(wu)的(de)(de)品質(zhi)。為了(le)保證衣(yi)(yi)物(wu)(wu)(wu)的(de)(de)品質(zhi),該(gai)鳥(niao)巢(chao)(chao)狀線(xian)頭(tou)必(bi)須(xu)得(de)人工二次(ci)修剪,從而增加了(le)工人的(de)(de)人工強度(du),并(bing)降低生產效率。

技術總結
本技術提供一種縫紉機少鳥巢剪線機構及縫紉機,縫紉機少鳥巢剪線機構包括都可運動地配置在旋梭外周側的起縫輔助動刀、縫后輔助動刀和主活動刀,主活動刀上設有第一落針槽、起縫切線刃和縫后切線刃,第一落針槽允許縫紉機中的機針通過,主活動刀能在起縫輔助動刀和縫后輔助動刀之間往復運動,使起縫切線刃與起縫輔助動刀咬合、或使縫后切線刃與縫后輔助動刀咬合。本申請在起縫時,通過起縫輔助動刀和主活動刀的運動,在起縫時先后使主活動刀上的第一落針槽運動至機針正下方、以及使起縫切線刃與起縫輔助動刀咬合,從而在起縫時捕捉到機針一側的面線線頭并將其切斷,避免起縫時形成鳥巢狀線頭,有效實現起縫防鳥巢,提高縫紉質量和效率。
