Embodiment 1

[0024] like figure 2 , image 3 As shown, a carton printing machine 100 of the present invention includes wallboards 101 on both sides and at least one set of printing units 102, and a printing press for entering cardboards with long sides and short sides is provided between the wallboards 101 on both sides. Inlet 103 , the printing inlet 103 leads to the printing unit 102 . In actual use, the number of groups of printing units 102 depends on the specific pattern to be printed. Each group of printing units 102 prints one color, and various exquisite patterns are formed by overlapping colors of multiple groups of printing units.

[0025] Similar to the prior art, each printing unit 102 includes an ink form roller 104 , a printing roller 105 , a printing plate 106 (such as a resin printing plate) and a vacuum box 107 . The vacuum box 107 is provided with a transmission wheel 108 (usually a ceramic wheel with a rough surface) and an embossing roller 109 . The printing plate ...

Abstract

The invention relates to the technical field of printing equipment and provides a carton printing machine which is more stable in conveying so as to improve the printing color register precision and the printing color register stability. The carton printing machine comprises wall plates at the two sides and at least one group of printing unit, wherein a printing entrance allowing paperboards to enter is arranged between the wall plates at the two sides and is communicated to the printing units, each group of printing unit comprises a printing roller, a printing plate and a vacuum box, each printing plate is arranged on the corresponding printing roller and is positioned between the corresponding printing roller and the corresponding vacuum box, each vacuum box is internally provided with an impressing roller and a conveying roller, the radial perimeter of each printing roller is matched with the length of the long sides of the printed paperboard, and the axial length of each printing roller is matched with the length of the short sides of the printed paperboard. The short sides of the paperboard are aligned with the printing entrance of the printing machine to enter the carton printing machine, and the paperboard and the vacuum boxes have the contact length of the long sides in the forwarding direction, so that the adsorption force is enhanced, the conveying is more stable, and the printing color register precision and the printing color register stability are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of printing equipment, and more specifically, to a carton printing machine and a printing method. Background technique [0002] The carton printing machine is a printing device that can print the required text, pattern and other information on the surface of the carton box. In the prior art, a carton printing machine usually includes multiple sets of printing units. The working principle of each group of printing units is: the printing plate hangs on the printing roller, the ink form roller inks the printing plate, and the cardboard is transported by the suction of the vacuum box and the transfer wheel with a rough surface to ensure that the transfer wheel, embossing roller, printing The line speed of the roller is consistent, and the process of "replicating" the pattern on the printing plate to the surface of the cardboard by the embossing roller. Each group of printing units prints one color, and...
