　　復(fu)卷機(ji)(ji)作為衛卷出(chu)產(chan)線設(she)備的第一站，復(fu)卷機(ji)(ji)運轉狀況良(liang)好(hao)與否直接影響后加工衛卷紙(zhi)(zhi)的質量及(ji)出(chu)產(chan)效率。復(fu)卷機(ji)(ji)要能正常運轉，而(er)且處于良(liang)好(hao)的出(chu)產(chan)狀況，除了各(ge)部(bu)件良(liang)好(hao)無損(sun)壞之外，整(zheng)機(ji)(ji)傳(chuan)動速(su)比(bi)的合理(li)調整(zheng)及(ji)操控非常重要。復(fu)卷機(ji)(ji)出(chu)產(chan)時原紙(zhi)(zhi)紙(zhi)(zhi)幅通(tong)過五道傳(chuan)動壓(ya)輥(gun)及(ji)皮帶(dai)傳(chuan)送(song)，即送(song)紙(zhi)(zhi)皮帶(dai)、弧(hu)形輥(gun)、后壓(ya)紙(zhi)(zhi)輥(gun)、前壓(ya)紙(zhi)(zhi)輥(gun)、收(shou)卷輥(gun)等(deng)。每一幅原紙(zhi)(zhi)都較(jiao)薄，伸(shen)長率有限，傳(chuan)動速(su)比(bi)不(bu)安穩的情況下，紙(zhi)(zhi)幅在復(fu)卷機(ji)(ji)不(bu)斷的加減(jian)(jian)速(su)運轉中易起(qi)皺及(ji)被拉斷。合理(li)的調整(zheng)和(he)操控各(ge)傳(chuan)動輥(gun)及(ji)送(song)紙(zhi)(zhi)皮帶(dai)線速(su)度能夠大大的削(xue)減(jian)(jian)紙(zhi)(zhi)幅被拉斷的現象。江門南天機(ji)(ji)械總結出(chu)以下幾點關鍵的調整(zheng)方法(fa)。

　　一(yi)、復卷(juan)機(ji)(ji)安(an)(an)穩送(song)紙(zhi)(zhi)皮(pi)帶(dai)傳(chuan)(chuan)(chuan)送(song)原紙(zhi)(zhi)紙(zhi)(zhi)幅的線速(su)度(du)(du)。現復卷(juan)機(ji)(ji)送(song)紙(zhi)(zhi)皮(pi)帶(dai)是由三(san)角皮(pi)帶(dai)通(tong)過(guo)無級調速(su)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)的，該(gai)種調速(su)輪(lun)在輸(shu)出(chu)轉矩較(jiao)大時(shi)，傳(chuan)(chuan)(chuan)動(dong)(dong)的三(san)角皮(pi)帶(dai)處(chu)于靠(kao)近調速(su)輪(lun)外沿方(fang)位，傳(chuan)(chuan)(chuan)動(dong)(dong)速(su)度(du)(du)才會愈加安(an)(an)穩。為了到達這(zhe)樣安(an)(an)穩的傳(chuan)(chuan)(chuan)動(dong)(dong)效果，能夠通(tong)過(guo)逐步調整主(zhu)機(ji)(ji)變速(su)箱的速(su)比，使(shi)收(shou)卷(juan)輥線速(su)度(du)(du)變慢一(yi)些，同時(shi)調節原紙(zhi)(zhi)架送(song)紙(zhi)(zhi)皮(pi)帶(dai)各個(ge)調速(su)手輪(lun)，使(shi)得(de)三(san)組傳(chuan)(chuan)(chuan)動(dong)(dong)三(san)角皮(pi)帶(dai)都處(chu)于無級調速(su)輪(lun)的外沿合理方(fang)位，直(zhi)至收(shou)卷(juan)輥與送(song)紙(zhi)(zhi)皮(pi)帶(dai)線速(su)度(du)(du)一(yi)致。

　　二(er)、復卷機調(diao)整(zheng)后(hou)壓(ya)紙(zhi)(zhi)(zhi)(zhi)(zhi)輥壓(ya)紙(zhi)(zhi)(zhi)(zhi)(zhi)空(kong)隙(xi)，讓紙(zhi)(zhi)(zhi)(zhi)(zhi)幅天然的在送(song)紙(zhi)(zhi)(zhi)(zhi)(zhi)皮(pi)帶與收卷輥之間滑潤傳(chuan)(chuan)送(song)。后(hou)壓(ya)紙(zhi)(zhi)(zhi)(zhi)(zhi)輥是紙(zhi)(zhi)(zhi)(zhi)(zhi)幅傳(chuan)(chuan)送(song)進程(cheng)的中(zhong)間環節，若(ruo)調(diao)整(zheng)的空(kong)隙(xi)過小(xiao)紙(zhi)(zhi)(zhi)(zhi)(zhi)幅易起(qi)皺而且下垂，空(kong)隙(xi)過大(da)(da)時(shi)三層紙(zhi)(zhi)(zhi)(zhi)(zhi)幅不(bu)合在一起(qi)易分層及斷層，影響送(song)紙(zhi)(zhi)(zhi)(zhi)(zhi)幅速度及復卷質量。調(diao)整(zheng)后(hou)壓(ya)紙(zhi)(zhi)(zhi)(zhi)(zhi)輥時(shi)應從(cong)小(xiao)到(dao)大(da)(da)漸(jian)漸(jian)增(zeng)大(da)(da)壓(ya)紙(zhi)(zhi)(zhi)(zhi)(zhi)空(kong)隙(xi)，使(shi)紙(zhi)(zhi)(zhi)(zhi)(zhi)幅剛好(hao)不(bu)起(qi)皺不(bu)下垂即(ji)可鎖緊定位螺釘。

　　三(san)、調(diao)整(zheng)(zheng)打(da)孔(kong)(kong)刀后方(fang)的(de)弧(hu)形(xing)軸(zhou)。該(gai)弧(hu)形(xing)軸(zhou)作(zuo)(zuo)為紙(zhi)(zhi)(zhi)幅(fu)收卷前，整(zheng)(zheng)幅(fu)紙(zhi)(zhi)(zhi)終究(jiu)舒展滑潤的(de)過(guo)渡(du)軸(zhou)。其方(fang)位(wei)的(de)高低及作(zuo)(zuo)業(ye)弧(hu)度(du)大小(xiao)不(bu)僅影響紙(zhi)(zhi)(zhi)幅(fu)的(de)滑潤度(du)，而且影響紙(zhi)(zhi)(zhi)幅(fu)傳送的(de)安(an)穩性。弧(hu)形(xing)軸(zhou)過(guo)高時，紙(zhi)(zhi)(zhi)幅(fu)遭到打(da)孔(kong)(kong)面刀的(de)刮碰，抖動(dong)大易斷(duan)紙(zhi)(zhi)(zhi)，方(fang)位(wei)過(guo)低時，紙(zhi)(zhi)(zhi)幅(fu)刮到打(da)孔(kong)(kong)低刀易斷(duan)層。一般(ban)調(diao)整(zheng)(zheng)弧(hu)形(xing)軸(zhou)方(fang)位(wei)高度(du)為讓紙(zhi)(zhi)(zhi)幅(fu)通過(guo)打(da)孔(kong)(kong)刀時，底層高于打(da)孔(kong)(kong)底刀5~8毫米(mi)為宜(yi)，弧(hu)形(xing)軸(zhou)的(de)作(zuo)(zuo)業(ye)弧(hu)度(du)越小(xiao)越好，紙(zhi)(zhi)(zhi)不(bu)起皺即可。

　　四(si)、復卷(juan)(juan)機(ji)調整(zheng)主機(ji)變(bian)速箱的(de)(de)內(nei)(nei)部(bu)齒(chi)(chi)鏈(lian)(lian)(lian)和外部(bu)鏈(lian)(lian)(lian)條，使得整(zheng)機(ji)的(de)(de)傳動(dong)(dong)愈加(jia)安(an)穩(wen)(wen)。衛卷(juan)(juan)紙(zhi)復卷(juan)(juan)機(ji)運(yun)轉(zhuan)時(shi)是通過(guo)自(zi)動(dong)(dong)加(jia)減(jian)速程序(xu)來操(cao)控頻頻的(de)(de)啟停(ting)，而且完結(jie)自(zi)動(dong)(dong)修邊封尾及換卷(juan)(juan)動(dong)(dong)作，因而對變(bian)速箱傳動(dong)(dong)速比的(de)(de)安(an)穩(wen)(wen)性要求較高。通過(guo)張(zhang)(zhang)緊(jin)(jin)其內(nei)(nei)部(bu)齒(chi)(chi)鏈(lian)(lian)(lian)和外部(bu)鏈(lian)(lian)(lian)條能夠避免鏈(lian)(lian)(lian)條的(de)(de)打滑及跳齒(chi)(chi)，使得速比在頻頻的(de)(de)加(jia)減(jian)速時(shi)愈加(jia)安(an)穩(wen)(wen)。張(zhang)(zhang)緊(jin)(jin)后的(de)(de)齒(chi)(chi)鏈(lian)(lian)(lian)上邊線(xian)用東西(xi)能夠上下撥動(dong)(dong)的(de)(de)起(qi)伏約5~8毫米為宜。
