Satellite type gravure press

Abstract

The invention discloses a satellite typed gravure press, which comprises sequentially distributed unreeling rollers, a printing mechanism, a drying mechanism and a reeling roller; wherein, the printing mechanism comprises a press roller; the circumference of the press roll is distributed with two or more printing rollers, which is equivalent to the working efficiency of a plurality of traditionalprinting presses, thus enhancing the printing efficiency; an inlet of the drying mechanism is provided with an air knife used for sweeping the surface of a printing stock and carrying out oxygen cleaning treatment; an outlet is provided with an air-stop device used for preventing external air from entering; in the entire drying process, the printing ink can not contact with the oxygen in the air thus avoiding chemical reaction. The satellite typed gravure press has the advantages of avoiding the addition of antioxidant in the printing ink, reducing the cost of the printing ink, being beneficial to the performance stability of the printing ink, reducing the production cost of printed materials and causing no pollution to the environment, and is characterized by simple structure, small volume, low power consumption and high printing efficiency. Therefore, the satellite typed gravure press is applicable to the occasions having relatively low requirement to printing quality.

Description

technical field [0001] The invention relates to a printing device, in particular to an ultraviolet drying satellite type gravure printing machine. Background technique [0002] Ultraviolet (UV) ink printing has the advantages of no solvent, fast drying, less energy consumption, good gloss, bright colors, water resistance, and good wear resistance. Ultraviolet (UV) ink printing machines have become a very It is an important printing equipment, which is to apply ultraviolet light curing (UV) ink on the printing material, and make the ink film-forming and drying under ultraviolet light. The drying oven of the current ultraviolet curing (UV) ink printer is open, and the printing material directly enters the drying oven after coating or printing ink, and the light curing agent in the ink will chemically react with oxygen in the air at high temperature , affect the quality of printing, and will produce a strong smell, causing environmental pollution, which is not conducive to env...

AI Technical Summary

Problems solved by technology

The drying oven of the current ultraviolet curing (UV) ink printer is open, and the printing material directly enters the drying oven after coating or printing ink, and the light curing agent in the ink will chemically react with oxygen in the air at high temperature , affect the quality of printing, and will produce a strong smell, causing environmental pollution, not conducive to environmental protection

[0003] In order to prevent the curing agent in the ultraviolet curing (UV) ink from reacting with oxygen in the air during the drying process and affect the printing quality, NH is added to the current ultraviolet curing (UV) ink 2 or OH and other antioxidants, the oxygen in the air reacts chemically with the antioxidants during drying to prevent oxidation by consuming oxygen, and in the printing process, due to the different thickness and density of the ink, the ink manufacturer is in the In the production process, it is difficult to grasp the proportion of antioxidants, often incomplete oxygen consumption or excess antioxidants

However, if the amount of photocuring in the ink is increased, its cost will also increase, and the power of ultraviolet drying must also increase accordingly, and the energy consumption will increase, resulting in a lot of increase in the production cost of printed matter.
