不干胶防伪标签印刷,胶印过程中掉纸的原因有哪些?

来源:http://www.shengfengyinshua.com/ 日期:2021-02-11 发布人:shengfeng 1.纸张不平服,呈波浪形。
1. The paper is uneven and wavy.
纸张不平服,造成输纸困难。特别是白板纸,极易产生前规走纸不到位,以致叼纸牙叼纸太少,甚至叼不住纸张,造成接纸牙排与递纸牙排无法正常交接而掉纸。
The paper is not flat, which makes it difficult to feed. Especially for whiteboard, it is very easy to cause that the front gauge paper is not in place, so that the paper teeth hold too little paper, or even can not hold the paper, resulting in the paper receiving teeth row and the paper delivery teeth row can not normally hand over and drop the paper.
2.纸张纸角上翘。
2. The corner of the paper is up.
纸张走至前规定位时,由于纸张叼口处纸角上翘,递纸牙在叼纸时牙片的高度低于纸角上翘高度,使递纸牙不能完全叼住,甚至在叼牙关闭的瞬间因碰到纸角,使纸张往回弹出,造成叼牙叼纸太少而掉纸。
When the paper is positioned by the front gauge, because the paper corner at the paper mouth is upwarped, the height of the paper delivery teeth is lower than the upwarped height of the paper corner when holding the paper, so that the paper delivery teeth can not hold the paper completely. Even when the paper corner is closed, the paper will pop back, causing the paper to drop because the paper is too little.
3.输纸出现双张。
3. There are two sheets in the paper feed.
当输纸出现双张故障时,重叠的两张纸就会出现一张稍快、一张稍慢的状况。在进入前规时,慢的一张就可能不能被叼牙完全叼住,从而掉到机器下面。

When there is a double sheet of paper failure, the overlapping two sheets of paper will appear a slightly faster, a slightly slower situation. When entering the front gauge, the slow one may not be fully held by the teeth in its mouth and fall under the machine.
4.输纸不正常。
4. Abnormal paper feeding.
由于机器调节不当,出现输纸歪斜、过快或过慢,造成递纸叼牙叼纸不稳而掉纸。
Due to the improper adjustment of the machine, the paper feeding is skewed, too fast or too slow, resulting in the instability of paper feeding and paper dropping.
5.前规定位距离不正确。
5. The positioning distance of the front gauge is incorrect.
纸张到达前规定位后,叼纸牙叼住纸张4~6毫米,太多则易撕破纸张,太少则因叼纸不充分而掉纸。
When the paper reaches the front gauge position, the paper teeth hold the paper for 4-6 mm. If the paper is too much, it is easy to tear the paper. If the paper is too little, it will fall off due to insufficient paper holding.
6.接纸牙排与压印滚筒大牙接触时间不对。
6. The contact time between the paper receiving teeth and the big teeth of the impression cylinder is not right.0
接纸牙排叼纸过早,则会把纸张叼破;太迟则会因叼不住纸张而产生掉纸。
If the pick-up teeth pick up the paper too early, it will break the paper; if it is too late, it will drop the paper because it can't hold the paper.
7.接纸牙排的叼力不够。
7. The holding force of the paper receiving teeth is not enough.
接纸牙排接纸到一半掉纸或个别牙排只有一半叼住纸张,则说明牙排叼力太轻,应重新调节叼纸力。
hen the pick-up teeth pick up half of the paper or only half of the individual teeth hold the paper, it means that the pick-up force of the teeth is too light, and the pick-up force should be adjusted again.
8.定位、输纸衔接时间不正确。
8. Incorrect connection time of positioning and paper feeding.
在纸张到达前规时,由于轮纸快慢与接规衔接时间不一致,造成输纸定位紊乱、接纸不好而掉纸。
When the paper reaches the front gauge, due to the inconsistency between the speed of the paper wheel and the connection time of the gauge, the paper feeding position is disordered, and the paper is dropped due to poor connection.
