印刷公司滾筒軸承磨損產生墨杠

印刷公司滾筒軸承磨損嚴重,產生墨杠。其原因是:膠印機使用一段時間後,滾筒軸端的軸套、偏心套或者軸承不可避免地磨損,特別是在油槽中進入污垢或斷油以後,磨損會更快,甚至很嚴重。

當合壓時,叼口部位受壓後產生離讓現象,引起滾筒錶面的滑動摩擦,從而在印刷品的叼口處產生幾條寬墨杠,有時還呈現等距離墨杠,特別是印版滾筒的軸頸和軸套嚴重磨損時,更容易產生這種墨杠,嚴重時會發展到叼口重影現象。

排除的方法:
有的機器磨損太嚴重時,可以在橡皮滾筒上墊襯紙時,把襯紙墊成梯形斜口,以便減少合壓時叼口所產生的撞擊力而引起的網點變形。但一定要調緊橡皮布壓住襯紙。如果機器軸套和軸頸磨損嚴重,只能更換新的軸頸和軸套,以徹底解決問題,使機器完成高檔印品的印刷。
