Printer for printing packaging paperboard

Abstract

The invention provides a printer for printing a packaging paperboard. The printer for printing the packaging paperboard comprises a paper inlet platform, a rack, a hairbrush arranged at the paper inlet of the rack, an air blowing pipe connected with an air compressor, a driving motor installed on the rack, an upper paper inlet pressure roller, a lower paper inlet pressure roller, a bottom pressure roller, a printing roller, an ink roller, an ink distribution roller, an upper paper outlet shaft and a lower paper outlet shaft, wherein the air blowing pipe is arranged at the paper inlet of the rack and is arranged on the inner side surface of the hairbrush; the two end portions of the upper paper outlet shaft and the lower paper outlet shaft are correspondingly provided with an upper paper outlet pressure roller and a lower paper outlet pressure roller; one end of the upper paper outlet pressure roller corresponding to one end of the upper paper outlet shaft and one end of the lower paper outlet pressure roller corresponding to one end of the lower paper outlet shaft are correspondingly provided with a trimming knife. The printer for printing the packaging paperboard has the beneficial effects that the phenomenon of white points exposed on the surface of a printed pattern is solved, the working efficiency is high and the qualification rate is high; the printed paperboard is cut off by 10mm from one end when the paperboard is output from the printer, and thus die-cut standard sides are guaranteed to be accurate and consistent.

[0002] Packaging cardboard needs to be printed during the processing and production process. There is only a cleaning brush at the paper inlet of the printing machine. This brush can only clean some large paper wool and confetti, and the brush has no obvious effect on some small confetti particles. , causing the paper scraps to cover the cardboard and enter the printing department, there will be white spots on the printed pattern, and there will be traces of paper scraps in the printing after the paper scraps stick to the printing plate. The printing machine has brushes that cannot be adjusted up and down. , the fine paper dust particles can not be completely removed and other problems

[0003] There is also the fact that packaging cardboard generally requires three steps of packaging cardboard production-printing-die-cutting in the processing process. For a packaging cardboard that needs to be printed with two small boxes, the edge of the printed pattern coincides with the folding line; The packaging cardboard is cut by a cutting knife during production. Since the packaging cardboard cutting knife is scissors-style and has a certain bevel, the edges of the packaging cardboard are not neat, which directly affects the alignment of the die-cutting and folding lines after printing. The problem of color position, so after the printing of the packaging cardboard, it is necessary to arrange personnel to measure the edge positions one by one with a box ruler, and then put the same position together and then die-cut.
