How to Deal with Printing Machine Failure?

Aug. 17, 2019

What should I do if the High Precision Printing Machine fails? Automatic Creaser Machine Supplier tells you that there are four main faults in the High Precision Printing Machine: paper break, water supply, inking, and stamping troubleshooting, overprinting failure and folding partial failure. Today we mainly talk about how to deal with the paper break of the Carton Box Printing Machine.

Broken paper is a very difficult thing, mainly for the following reasons:

(1) Edge cracking, tight edges, side bumps or glue on the sides. When the glue is stuck on the tight side or the side of the paper, the paper tape is easy to break, which affects the normal paper feeding. It has been found that such a phenomenon can be wetted by a water brush or glued to the side of the glue, and the fault is eliminated.

(2) The core of the paper roll itself is not round. The operator can judge whether the eccentricity of the core is too large by experience, and change the paper in time or notify the machine administrator to slow down the operation to avoid it.

(3) The lifting speed is too fast or the tension is too large. The paper has a tension limit. When tightening the tension, try to stay away from the ultimate tension. At high speeds, a very small change can also cause very large stresses that can cause paper breaks.

(4) The guide roller core shaft is loose, the level and parallelism are not accurate, and the mandrel or bearing is worn. For the use of the High Precision Printing Machine, which has been in use for a certain period of time, sufficient attention should be paid to it. Maintenance personnel and operators should check the working condition of the paper guide roller in time.

(5) Excessive deposit of ink on the paper guide roller. After a long period of time, the deposition of smog increases the radius of each roller, which in turn increases the tension. When the tension reaches the limit, the machine cutter will cut the paper protection. Therefore, the dirt deposited on the paper guide roller should be removed in time.
