Rolling digital printing device

Abstract

The invention provides a rolling digital printing device which primarily comprises a roller. The rolling digital printing device is successively provided with a cleaning device, a first coating device, a drying device, a second coating device, a spray printing device, a gluing unit and a compounding unit around the roller according to steps. The rolling digital printing device also comprises a printed material and an unreeling mechanism thereof. The compounding unit combines the printed material with a transfer layer formed by a plurality of stations through the roller. The transfer layer is combined with the printed material to form a comprehensive layer which is pulled by a guide roller to leave the compounding unit and the roller. The comprehensive layer leaves the compounding unit andthe roller and is rolled by a rolling mechanism through the first drying device, a polishing device and a second drying device. By means of characteristics of section, smoothness, cyclic rotation andthe like of the roller, a set of digital printing mode combined with the transfer layer to transfer the printed material is formed, so that the product quality is stable, the failure rate is low and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a rolling digital printing device. Background technique [0002] With the development of big data and the advancement of mobile terminals, variable two-dimensional codes have become an important means of commodity information storage and anti-counterfeiting, especially under the intelligent network, it is necessary to achieve one code per item, and variable two-dimensional codes are currently It has been used in large quantities on cigarette packs and medicine boxes, providing a basis for intelligent logistics and sales control, so digital printing has become a new printing method and has gradually appeared in printing companies. [0003] At present, with the development of society, there are more and more personalized printing, or small-batch and multi-variety printing. Traditional printing methods such as offset printing and gravure printing have long time to change pr...

AI Technical Summary

Problems solved by technology

However, there are certain problems in the digital printing method, which is mainly reflected in the relatively high demand for the substrate, because the inkjet printing ink cannot adapt to all substrate surfaces, and at the same time, the nozzles for printing are very precise, and the distance from the substrate during printing is very long. When moving near and at high speed, it is easy to make the dust on the substrate or the substrate itself often contact with the nozzle, resulting in abnormal printing. Whether it is electronic ink or other ink printing methods, there are certain defects, so it can only be used in a small range. , which is the main reason why the printing method of digital jet printing has not been promoted for so many years. There is an urgent need for a technical solution to the adaptability of digital printing methods in the industry.
