UV ink printing layer drying device

Abstract

The invention discloses an UV ink printing layer drying device. The UV ink printing layer drying device comprises a base, a left support rod and a right support rod; the left support rod is arranged on the upper side of the base; and the right support rod is arranged on the side, far from the left support rod, of the base. The UV ink printing layer drying device has the following beneficial effects: through arrangement of an oxygen absorbing machine, oxygen can be effectively removed, so that the drying quality of an ink layer is guaranteed, and the printing cost is reduced; through arrangement of a heating roller, the drying effect of the ink layer on papers is further improved; and through arrangement of an ink bonding prevention layer, the ink layer can be prevented from bonding on an output roller to guarantee the printing quality of the papers.

Description

technical field [0001] The invention relates to the printing field, in particular to a UV ink printing layer drying device. Background technique [0002] UV printing is a printing process that dries and cures ink by ultraviolet light. It needs to match the ink containing photosensitizer with UV curing lamp. The application of UV printing is one of the most important contents in the printing industry. UV printing is a highly reliable process. For example, some fractions of traditional sheet-fed inks in the United States are classified as volatile organic components (VOCs), which are controlled by law and are within limits--in these areas, UV is usually classified as "best available process" list. In the European Union, ink fractions for sheet-fed printing are not classified as a VOC hazard either. The drying process of the printing layer of UV printing plays a very important role, but the existing drying device needs to use nitrogen to isolate the oxygen in the air when d...

AI Technical Summary

Problems solved by technology

The drying process of the printing layer of UV printing plays a very important role, but the existing drying device needs to use nitrogen to isolate the oxygen in the air when drying the ink, because oxygen will reduce the drying ability of the ultraviolet lamp and the utilization rate of the photoinitiator. However, the cost of nitrogen gas is high, which greatly increases the printing cost. At the same time, the paper can only be dried by a simple ultraviolet lamp when drying, which reduces the drying efficiency. Moreover, the ink layer is often stuck by the output roller when it is conveyed after drying. connection, so that the printing quality cannot be guaranteed, so a new type of device is needed to solve the existing problems
