印刷公司印刷機出現印品甩角的原因如下
關於印刷公司印刷機印品甩角

印刷公司印刷機出現印品甩角的原因如下

(1)遞紙牙在遞紙牙台叼紙時,由於遞紙牙的牙片閉牙時間不一致在加速遞送中紙張有錯動,壓印滾筒叼牙接過不夠平整的紙張,造成印刷後甩角現象。

(2)遞紙牙機構長期使用,使靠塞彈簧疲勞過度損壞或靠塞螺釘未能固定好,使遞紙牙閉牙時碰撞紙邊,使其向後拖,交給第色壓印滾筒叼紙牙排時,各叼牙叼口不一致,進入後面印刷造成甩角。

(3)遞紙牙閉牙時間調得太晚在遞紙牙開始加速運動時,還未完全閉合,造成與第一色壓印滾筒交接時,紙張不穩定,印刷後造成甩角。

(4)遞紙牙排上有個別牙閉牙失靈,似閉非閉,到叼紙時未打開的牙碰紙張邊口或有的叼口叼紙力太大,叼紙太緊,使整個叼紙力不一致,碰紙邊口的牙使紙邊向後拖,印刷中造成甩角。

(5)遞紙牙開牙滾子有嚴重磨損,或者遞紙牙開閉牙凸輪磨損部調節不當,使遞紙牙交接紙張的時間不準確,造成交接中紙張的錯動,印刷後造成甩角。

(6)遞紙牙閉牙大彈簧疲勞過度(或折斷),彈簧桿軸或軸承磨損,驅動遞紙牙擺的凸輪和滾子磨損,所有這些原因之一,均可造成遞紙牙運動的不準確,而破壞了遞紙牙交接紙張的準確性,而印刷後均會造成甩角現象。

(7)遞紙牙機構的保養和潤滑不好造成配合零件的磨損,使遞紙牙軸運動不靈活,造成交接時間不準確,或是遞紙牙叼紙力不足,使叼牙部位紙邊後拖,形成印刷後的甩角現象。
