深圳印刷公司印刷機壓印滾筒的調節

印刷公司印刷機壓印滾筒的調節是指壓印滾筒整排叼紙牙的叼紙力一致及每個叼紙牙的調節。

在壓印滾筒的叼牙軸上安裝有15個叼牙(對開機),卡箍用緊固螺釘緊固在叼牙軸上,牙體騎在卡箍兩側並活套在叼牙軸上,在牙體上裝有牙片,依靠彈簧使牙片與牙墊始終接觸,其接觸力的大小,可通過調節螺釘來調節。當叼牙軸逆時針方向轉動時,卡箍也隨逆時針方向轉動,卡箍的凸輪頂動調節螺釘使牙體抬起,使牙片開牙。

(1)壓印滾筒整排牙叼紙力的調節。
調整時,在叼牙軸上的靠塞定位塊與靠塞螺釘之間墊0.25mm厚的紙,將卡箍的螺釘松開在牙片和牙墊之間墊上一條與叼牙同寬的牛皮紙,用手擰動牙體和卡箍,使牙片壓住牛皮紙並鎖緊緊固螺釘,註意牙體與卡箍應平行,然後抽出牛皮紙,使各個叼牙松緊一致。即叼紙力大小一致即可。
最後撤出叼牙定位螺釘與靠塞定位塊之間的墊紙,壓印滾筒的叼牙即可工作。

(2)壓印滾筒單個牙的叼紙力調節。
在印刷過程中,有時出現叼紙牙叼紙力不一致,此時對於叼紙力小者需要進行調節。這可以通過調節螺釘來實現。擰動調節螺釘壓縮小彈簧來增加叼紙牙片的叼紙力,同時還要求控制叼牙叼紙和開牙放紙的時間,使各叼牙開閉時間一致,此時可通過調節螺釘來完成。
