Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing and reeling mechanisms, in particular to a packaging printing and reeling mechanism. Background Art
[0002] UV curing means that under the irradiation of ultraviolet light, the photoinitiator absorbs the radiation energy of ultraviolet light and splits into free radicals, which triggers the polymerization, cross-linking and grafting reactions of prepolymers, and solidifies into a network polymer in a very short time. As a result, UV coatings, inks, adhesives, etc. are converted from liquid to solid within a few seconds to form a pattern.
[0003] In the process of large-area solid printing, due to the large amount of ink applied and the thick ink layer, the ink layer on the surface of the printed product will appear to be completely dry on the surface but not completely dry on the bottom layer during the drying process, which is called the false drying phenomenon. In addition to the thick ink layer, insufficient paper feed speed and UV light exposure time can also cause the UV ink to be falsely dry. Once the ink false drying phenomenon occurs, it is easy to cause the ink layer on the surface of the printed product to fall off during the post-processing process. This is because the bonding strength between the incompletely dried ink bottom layer and the surface of the substrate is poor, so that the ink layer is scratched and falls off under the action of friction. In the prior art, the UV light exposure time and the power of the UV lamp can be adjusted according to the paper feed speed of the printing press, but the UV lamp may be opened or closed during use. When the UV lamp is forgotten to be turned on, the ink will not dry. When the UV lamp is forgotten to be turned off, the UV lamp will be used for a longer time than the usable time, resulting in a decrease in the power of the UV lamp. When the UV lamp irradiates the printing ink, the ink still has the problem of false drying. Utility Model Content
