Offset printing machine is a high speed and high quality printing machine imported from abroad in recent years. It has many outstanding advantages, such as printing speed, printing layout, quality stability, effectiveness, etc., but also prone to some failures, which is a kind of boring car is a headache. The stuffy vehicle is due to lost paper, front gauge, pulling gauge, feeding system and gauge detection system failure, between a few or even a dozen sheets of paper into the embossing drum and rubber roller, caused by the sudden stop phenomenon.

The reason the stuffy car generally has the following kinds of paper printing machine:

1, the paper plate height adjustment inappropriate pressure front disc. Generally should be 3 printing paper thickness.

2, transport between paper and paper board, the gap between the feed roller and feed roller adjustment. General printing paper width is less than 5.5mm of paper over three but two, more than 5.5mm of paper over three but four. In addition, the photoelectric dual controller is not adjusted in place will also cause double Zhang into the roller.

3, printing machine in the normal work, if the paper arrives at the front of the front, late, skew, lack of angle, roll edge, photoelectric detection immediately ordered to stop swinging, in order to prevent paper and then into the roller. At the same time the swing gripper teeth do not out of paper machine, reducer, roller, pressure from a version of roller lift water roller and roller swing stop. At this time, if the electrical control line failure is very easy to put a stack of paper rolling embossing drum and rubber roller, resulting in the stuffy vehicle.

4, the paper operating personnel from work, when the paper is abnormal without timely treatment, which is the most common cause of feed in the mirror.

5, because of the paper stack is uneven, a stack of paper plug wood, stack with the pad below around the demolition note object are not handled in a timely manner, may also transfer to the paper with the former syndiospecific, rolling into the drum, resulting in the stuffy vehicle.

6, lost paper and related parts is not adjusted, the paper also prone to abnormal, stuffy car.

7, if it is printed with coated paper, due to the large amount of printing ink, easy to cause adhesion, while the operator in the paper on paper is not done through loose paper processing, it may cause a stack of paper rolling drum machine into adhesion, occurrence of stuffy car.
