High-speed wide full-color water-based ink-jet printing mechanism for reel base material

Abstract

The invention belongs to the technical field of printing equipment, and particularly relates to a high-speed wide full-color water-based ink-jet printing mechanism for a reel base material. The high-speed wide full-color water-based ink-jet printing mechanism comprises a rack, a jet printing cylinder and a compression roller are rotationally mounted on the rack, a jet printing assembly is arranged on the rack and located above the jet printing cylinder, and a drying device is arranged on the rack. According to the high-speed wide full-color water-based ink-jet printing mechanism for the reel base material, the jet printing cylinder is adopted for conveying the base material, stability is improved, the width of the base material can exceed 1 m, the conveying speed of the base material is high and exceeds 100 m/min, a cooling structure is arranged in the jet printing cylinder and is used in cooperation with the drying device, the temperature of the surface of the jet printing cylinder and the temperature of the base material of the jet printing cylinder are kept constant, the elongation of the base material is stable, and four-color or multi-color unbiased registration based on the water-based ink is achieved.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a high-speed and wide-width full-color water-based inkjet printing mechanism for a roll base material. Background technique [0002] There are a variety of printing methods in the printing and packaging industry, including flexo printing, gravure printing, offset printing, digital printing, etc. Among them, digital printing is an emerging printing method in recent years. It has the characteristics of high efficiency, low cost in small batches, and simple operation. trend in recent years. [0003] At present, in high-speed inkjet digital printing technology, two kinds of ink materials, UV and water-based, are usually used. However, due to the strong pollution of UV ink and the good environmental protection of water-based ink, water-based ink is used more and more recognized. [0004] In the watermark and inkjet industry, the substrate is dragged and convey...

AI Technical Summary

Problems solved by technology

[0004] In the watermark and inkjet industry, the substrate is dragged and conveyed in a horizontal way, usually with a belt structure. This method can be realized for black and white printing, but for color equipment, due to the long path, the substrate is easily caused during the conveying process. The swing of the material cannot achieve the registration of the four colors (CMYK)
