印刷工藝覆膜機上膠輥與塗膠輥間的間除

要根據復合工藝的要求來調節兩輥之間的工作間隙。調間隙時,把塞尺插入兩輥之間,旋動間隙調節螺釘,當塞尺在兩輥之間有接觸感,能抽動並稍有阻力時,間隙則合適;如果抽動輕松表示間隙過大;可逆時針方向慢慢地轉動手輪,直至獲得滿意的間隙。


反之
,阻力過大或抽不動,表示間隙過小,可轉動手輪調至手感正
常即可。還須調節兩輥左右兩端的間隙,使兩端間隙相等,兩輥平行,才可保證塗膠均勻。否則,可松動齒輪箱上的蝶形螺母,旋動調節螺釘,使間隙相等,然後緊固蝶形螺母保持正常位置。


手輪端部裝有刻度盤和指針
,每小格讀數為0.01mm,每周讀
數1.5mm。當手輪轉動1小格時,塗膠輥移動0.01mm,其餘類推實際間隙的大小必須與刻度盤上指針所指的讀數一致,否則,可調動指針的位置,機器壁上裝有刻度尺,供兩輥間隙粗調之用。


值得註意的是
,禁止兩輥互相接觸和碰撞。工作時,等上膠輥底
部泡浸在膠液里後,方能使兩輥正常運轉,以免損傷兩輥錶面。然後用手小心地操動刮膠刀方軸手柄,讓刮膠刀慢慢地與塗膠輥貼合,時可適當施加小壓力,使其貼合效果更好,然後擰緊方軸固定螺釘以緊固方軸。刮膠刀片與塗膠輥的貼合要平整,否則,可調整方軸調節螺釘,使其貼合平整。最後緊固手輪軸上的壓緊螺釘。停止工作時,上膠輥、刮膠刀及刀架必須與塗膠輥分開。
