[0001] The present invention relates to the technical field of cardboard processing equipment, in particular to the technical field of jet printers. Background Art

[0002] Corrugated cardboard has good ductility and mechanical strength and is often used as packaging for transportation and promotional purposes. During the production process, corrugated cardboard requires printing, applying QR codes and other information codes to the surface of the cardboard to facilitate identification of the specifications of the corrugated box. However, existing corrugated cardboard printing equipment feeds the cardboard under the printer's nozzle for printing. After printing, the cardboard is directly discharged and stacked. This prevents the ink on the cardboard from drying in time, causing the ink to smudge and making the corresponding information unrecognizable. Summary of the Invention
