一、電子提花機是做什么的
電子(zi)提(ti)(ti)花(hua)(hua)機是(shi)(shi)一種紡(fang)織(zhi)設(she)備,給(gei)織(zhi)物(wu)提(ti)(ti)花(hua)(hua),相(xiang)當于電腦(nao)刺繡樣的。電子(zi)提(ti)(ti)花(hua)(hua)機是(shi)(shi)指提(ti)(ti)花(hua)(hua)機的選(xuan)針機構是(shi)(shi)電腦(nao)來控(kong)制的,一般來說電子(zi)提(ti)(ti)花(hua)(hua)機比機械提(ti)(ti)花(hua)(hua)機能(neng)做的花(hua)(hua)紋要多。
二、電子提花機工作原理
在(zai)提(ti)(ti)花機(ji)上(shang)(shang)(shang)(shang),紋(wen)(wen)板(ban)套在(zai)花筒上(shang)(shang)(shang)(shang),每織(zhi)一緯(wei)翻過一塊紋(wen)(wen)板(ban),花筒向(xiang)橫針(zhen)(zhen)(zhen)靠壓一次。當(dang)紋(wen)(wen)板(ban)上(shang)(shang)(shang)(shang)有(you)孔眼時(shi),橫針(zhen)(zhen)(zhen)的(de)頭端(duan)伸進紋(wen)(wen)版及花筒的(de)孔眼,使直針(zhen)(zhen)(zhen)的(de)鉤端(duan)仍掛在(zai)提(ti)(ti)刀上(shang)(shang)(shang)(shang)。當(dang)提(ti)(ti)刀上(shang)(shang)(shang)(shang)升(sheng),直針(zhen)(zhen)(zhen)跟著(zhu)上(shang)(shang)(shang)(shang)升(sheng),通(tong)過首線鉤子和通(tong)絲(si)(si)帶動(dong)(dong)綜(zong)(zong)(zong)絲(si)(si)提(ti)(ti)升(sheng),此(ci)時(shi)穿(chuan)入綜(zong)(zong)(zong)眼的(de)經(jing)絲(si)(si)也(ye)(ye)隨著(zhu)提(ti)(ti)升(sheng),形成(cheng)梭口(kou)的(de)上(shang)(shang)(shang)(shang)層(ceng)。在(zai)綜(zong)(zong)(zong)絲(si)(si)的(de)下綜(zong)(zong)(zong)環中吊(diao)有(you)綜(zong)(zong)(zong)錘(chui),在(zai)梭口(kou)閉合時(shi),依(yi)靠其重量起(qi)回綜(zong)(zong)(zong)作用。當(dang)紋(wen)(wen)板(ban)上(shang)(shang)(shang)(shang)無孔眼時(shi),橫針(zhen)(zhen)(zhen)后退通(tong)過凸(tu)頭,推動(dong)(dong)對應的(de)直針(zhen)(zhen)(zhen),使直針(zhen)(zhen)(zhen)鉤端(duan)脫離提(ti)(ti)刀,因此(ci)與直針(zhen)(zhen)(zhen)相連的(de)綜(zong)(zong)(zong)絲(si)(si)和經(jing)絲(si)(si)均不提(ti)(ti)升(sheng),經(jing)絲(si)(si)就(jiu)(jiu)沉在(zai)下面,形成(cheng)梭口(kou)的(de)下層(ceng)。所以每根(gen)經(jing)絲(si)(si)的(de)運(yun)動(dong)(dong)是根(gen)據紋(wen)(wen)板(ban)上(shang)(shang)(shang)(shang)有(you)孔或無空來決(jue)定的(de),紋(wen)(wen)板(ban)上(shang)(shang)(shang)(shang)的(de)孔則是根(gen)據花紋(wen)(wen)和組織(zhi)的(de)設計要求軋(ya)成(cheng)的(de),因此(ci)經(jing)絲(si)(si)的(de)運(yun)動(dong)(dong)也(ye)(ye)就(jiu)(jiu)符合紋(wen)(wen)樣(yang)和組織(zhi)的(de)要求。
三、提花的工藝來源
提花(hua)的工藝(yi)方法源自(zi)原(yuan)始腰機(ji)(ji)挑花(hua),漢代(dai)(dai)(dai)時這種工藝(yi)方法已經(jing)用于(yu)斜織機(ji)(ji)和水平織機(ji)(ji)。花(hua)本式提花(hua)機(ji)(ji)出現(xian)于(yu)東(dong)漢,又稱(cheng)花(hua)樓。是我國古代(dai)(dai)(dai)織造技(ji)術最高成就的代(dai)(dai)(dai)表。提花(hua)機(ji)(ji)后(hou)經(jing)絲綢之(zhi)路傳入西方,對現(xian)代(dai)(dai)(dai)電子(zi)計算機(ji)(ji)發展中程序控(kong)制與(yu)存儲技(ji)術的發明(ming)有啟示作(zuo)用。
