紙箱(xiang)機(ji)(ji)的(de)(de)(de)傳(chuan)(chuan)動(dong)(dong)鏈可分為外傳(chuan)(chuan)動(dong)(dong)鏈和內傳(chuan)(chuan)動(dong)(dong)鏈。外傳(chuan)(chuan)動(dong)(dong)鏈是從(cong)動(dong)(dong)力(li)源至(zhi)紙箱(xiang)機(ji)(ji)主軸或(huo)分配(pei)軸的(de)(de)(de)傳(chuan)(chuan)動(dong)(dong)，多采(cai)用皮帶傳(chuan)(chuan)動(dong)(dong)和摩(mo)擦傳(chuan)(chuan) 動(dong)(dong)等(deng)，不保證(zheng)嚴格(ge)的(de)(de)(de)傳(chuan)(chuan)動(dong)(dong)比。這種傳(chuan)(chuan)動(dong)(dong)鏈通常稱(cheng)為紙箱(xiang)機(ji)(ji)的(de)(de)(de)主傳(chuan)(chuan) 動(dong)(dong)，即電機(ji)(ji)至(zhi)滾筒(tong)的(de)(de)(de)傳(chuan)(chuan)動(dong)(dong)。它的(de)(de)(de)功能(neng)是:把動(dong)(dong)力(li)源的(de)(de)(de)功率傳(chuan)(chuan)遞給執(zhi) 行機(ji)(ji)構;保證(zheng)執(zhi)行機(ji)(ji)構具(ju)有(you)一定(ding)的(de)(de)(de)轉速(su)和一定(ding)的(de)(de)(de)調速(su)范圍;能(neng)方便(bian) 地(di)進行機(ji)(ji)器的(de)(de)(de)啟動(dong)(dong)和制動(dong)(dong)。
內傳動(dong)(dong)(dong)(dong)鏈是使執行機(ji)構(gou)按照要求的(de)規(gui)律運(yun)動(dong)(dong)(dong)(dong)，并(bing)能(neng)(neng)保證傳動(dong)(dong)(dong)(dong) 精(jing)度的(de)傳動(dong)(dong)(dong)(dong)鏈。它的(de)功(gong)能(neng)(neng)是:進行運(yun)動(dong)(dong)(dong)(dong)和功(gong)率的(de)傳遞;保證運(yun)動(dong)(dong)(dong)(dong)與 運(yun)動(dong)(dong)(dong)(dong)之間嚴(yan)格的(de)速比;完成運(yun)動(dong)(dong)(dong)(dong)之間的(de)協調配合。它一般(ban)由四桿 機(ji)構(gou)、凸輪機(ji)構(gou)、間歇機(ji)構(gou)及各種組合機(ji)構(gou)組成。
離合(he)器的離合(he)靠電(dian)(dian)磁鐵(tie)控(kong)制(zhi)。正常工(gong)(gong)作(zuo)(zuo)時電(dian)(dian)磁鐵(tie)不通(tong)(tong)電(dian)(dian)，在 彈(dan)贊的作(zuo)(zuo)用下，被動(dong)牙與主(zhu)動(dong)牙接(jie)通(tong)(tong)，將運動(dong)由(you)主(zhu)機(ji)傳給給紙(zhi)機(ji) (如圖示位(wei)置);當出現雙(shuang)張(zhang)、紙(zhi)張(zhang)歪斜、空張(zhang)等故(gu)障時，通(tong)(tong)過(guo)雙(shuang)張(zhang)控(kong) 制(zhi)器、自動(dong)離合(he)機(ji)構接(jie)通(tong)(tong)電(dian)(dian)磁鐵(tie)電(dian)(dian)源，電(dian)(dian)磁鐵(tie)吸合(he)，連桿向上移(yi)動(dong)， 再(zai)通(tong)(tong)過(guo)撥動(dong)被動(dong)牙克服彈(dan)簧(huang)的壓(ya)力使之向右移(yi)動(dong)，從而將主(zhu)動(dong)牙 與被動(dong)牙脫開，給紙(zhi)機(ji)立(li)即停止(zhi)工(gong)(gong)作(zuo)(zuo)。
