Description

TECHNICAL FIELD

[0001] The utility model belongs to the intaglio printing technical field, concretely relates to a printing machine drying air pipe subassembly. BACKGROUND

[0002] Intaglio printing is one of four printing methods. When printing, ink is filled into the pits, and the ink in the pits is transferred to the printing material to complete printing. As a printing process, intaglio printing has the advantages of thick ink layer, bright color, high saturation, high printing plate resistance, stable printing quality, and fast printing speed, and occupies an extremely important position in the field of printing packaging and graphic publishing.

[0003] Current intaglio printing has high pollution and high energy consumption. The state has been strictly supervising and managing the dilution of intaglio printing ink, and has formulated detailed emission standards for VOCs gas emitted during printing and drying of solvent ink and alcohol-water ink diluent. When treating the emitted VOCs gas, more energy consumption is consumed. With the increasing awareness of low-carbon environmental protection among the public, pure water-based ink, as an environmentally friendly ink, will become the future trend of the printing industry due to its environmental protection characteristics of no solvent volatilization and residue. With the application of the environmental protection characteristics of pure water-based ink, solvent ink will be replaced, and low-carbon environmental protection printing will become the mainstream of the development of the printing industry in the future.

[0004] Because the diluent solvent of solvent ink can be quickly volatilized by heating the air, the water content in pure water-based ink is not as easy to volatilize as traditional diluent solvent. It is difficult to dry the water content in the ink by simply heating the air in the traditional way, which reduces the printing speed and reduces the production capacity. UTILITARY MODEL CONTENT
