Description

Technical Field

[0001] The present invention relates to the technical field of printing processing, in particular to a low-temperature drying method and device for water-based UV curing ink. Background Art

[0002] Water-based UV curing ink is an environmentally friendly printing material that combines a water-based formula with ultraviolet curing technology. It is mainly used in the field of packaging and printing with high hygiene standards. It is suitable for packaging and printing of tobacco, alcohol, food, beverages, medicines and children's toys with strict hygiene requirements. It is also compatible with screen printing processes to overcome the limitations of gravure printing.

[0003] After the water-based UV curing ink is printed on the substrate, it needs to be dried by a low-temperature drying device so that the water-based UV curing ink can be quickly solidified on the surface of the substrate.

[0004] However, the existing low-temperature drying device still has the following technical problems when in use:

[0005] (1) The current low-temperature drying method mainly heats the air flow and dries the water-based UV curing ink through the air flow at a certain temperature. However, the current air flow does not have a filtering step during the blowing process, resulting in a small amount of dust mixed in the air flow. When the air flow comes into contact with the water-based UV curing ink, the dust will adhere to the surface of the water-based UV curing ink, thereby affecting the processing quality;

[0006] (2) After drying, the water-based UV curing ink will be further irradiated by a UV lamp to increase its drying effect. However, with long-term use, a large amount of dust will adhere to the surface of the UV lamp. This dust affects the irradiation of light and thus affects the drying effect.

[0007] Therefore, a low-temperature drying method and device for water-based UV curing ink are proposed to solve the above-mentioned problems. Summary of the Invention

[0008] The object of the present invention is to provide a low-temperature drying method and device for water-based UV curing ink to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned object, the present invention provides the following technical solution: a low-temperature drying method for water-based UV curing ink, the specific steps of the low-temperature drying method are as follows;

When the carrier platform is completely moved into the interior of the drying box, the right side of the carrier platform blocks the right end cavity of the drying box to ensure that the hot air inside the drying box does not leak as much as possible. Start the exhaust device and the electric heating device. The exhaust device has an exhaust fan inside to discharge the external air flow into the interior of the electric heating box, and heat the air flow through the internal electric heating device. Finally, it is discharged through the drying air outlet plate to perform the initial drying of the water-based UV curing ink on the upper surface of the printing carrier;
