也可以減少膠輥膠圈的損壞和損傷,這也是棉紗質(zhì)量保持穩(wěn)定、減少棉紗疵點(diǎn)的重點(diǎn)。牽伸和卷繞部件隨著每天清潔次數(shù)的增加,飛花附入牽伸和卷繞部件的幾率降低,膠輥膠圈纏繞幾率下降,膠輥膠圈損傷、損壞的程度明顯下降;隨著紡紗號(hào)數(shù)的增加和棉紗質(zhì)量要求提高,膠輥膠圈纏繞、損傷、損壞的程度更加明顯,增加牽伸和卷繞部件的清潔頻次是行之有效的。在生產(chǎn)普通號(hào)數(shù)棉紗時(shí),牽伸和卷繞部件每班清潔兩次膠輥膠圈的損傷、損壞只有牽伸和卷繞部件每天清潔一次的10%~20%。實(shí)踐證明,牽伸和卷繞部件合理的清潔頻次和適當(dāng)增加清潔頻次,是保證膠輥膠紡紗完整的重要環(huán)節(jié)。

mm，可分三次走刀，進(jìn)刀量分別可為0.4 mm、0.3 mm、0.3 mm，這樣有利于降低膠輥表面溫度。由于粗磨對(duì)膠輥表面粗糙度無(wú)嚴(yán)格要求，主要是保證膠輥表面圓柱度。粗磨后不應(yīng)立即進(jìn)行精磨，要將并條膠輥放置48 h，使其經(jīng)時(shí)效處理后進(jìn)行。精磨膠輥時(shí)可選用粒度為60、70、80號(hào)，寬度為30 mm的大氣孔砂輪，磨削總量一般為0.5 mm，棉紡企業(yè)一般*需進(jìn)行復(fù)磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進(jìn)行，進(jìn)刀量分別可為0.2 mm、0.1 mm、0.1 mm，采用小負(fù)荷磨削可使膠輥表面熱量受到控制，磨削粉塵也較少，更有利于砂輪的清潔與鋒利。在砂輪安全線速度的前提下，為保證磨礪質(zhì)量，一般砂輪主軸轉(zhuǎn)速為1800 r/min，相應(yīng)車(chē)頭轉(zhuǎn)速約為200 r/min。磨削前需要調(diào)整好磨床尾座，保證磨削后膠輥兩端錐度不大于0.03 mm，磨削行程要設(shè)置為自動(dòng)走刀以保證磨削速度均勻，之后一次走刀速度要慢，以3 m/min～4 m/min為宜。精磨后膠輥膠層應(yīng)細(xì)膩、光滑，目測(cè)其表面無(wú)螺旋線，無(wú)機(jī)械波紋，表面粗糙度Ra值達(dá)到0.4 μm～0.6 μm為好。上海擠干輥生產(chǎn)線</p></p><br /><p>文章來(lái)源地址:
