1. The phenomenon of ink stick caused by uncomfortable printing pressure: The culprit for this kind of failure is the sliding friction phenomenon in the printing process of the carton printer. Sliding friction comes from: First, the bearing of the blanket cylinder is seriously worn. Second, the use of hard lining, embossing process due to the roller gear wear is serious, and the distance between the center of the drum is too large, resulting in the gear side gap gradually becomes larger, after the drum is pressed together after the gear can not be due to fluctuate and then friction. Both of these situations can be solved by replacing the cylinder bearing of the carton printer and reducing the distance between the center points of the rollers.

2. Overprinting failure caused by inaccurate cylinder teeth: When the tooth surface of the roller bite is worn and deformed, the pressure of the teeth is uneven and insufficient. When the printed sheet enters the teeth, it is prone to slip phenomenon, resulting in inaccurate overprinting. Quality of products. The method to solve such problems is to remove the severely worn teeth and replace them with new ones, and adjust and correct the uneven pressure and insufficient teeth. In addition, a method of appropriately reducing the printing pressure of the carton printer may also be adopted.
3, carton printing machine board paper surface strength is too bad to cause powder off, hair loss, peeling and other phenomena: the surface of the paper in the printing process, due to external forces such as printing peel force and ink viscosity, resulting in paper coating and surface layer Tissue fragmentation and peeling, the appearance of silty substances on the surface of the paper. The simplest solution to this type of problem is to use paperboard presses with strong surface and good quality paper.
