A uv primer roller coating device

Abstract

The invention discloses a UV (Ultra Violet) prime paint roll coating device. A clamping device is adopted to downwards compress a box cover or a box body transmitted on a conveyer belt, then UV prime paint coating is carried out on the two relative edges of the box cover or the box body in the opening direction through PU rollers on single-side roller-coating devices relatively arranged on the two sides of the conveyer belt, paint is supplied by the prime paint on the PU rollers through spraying pipes arranged on oil storage tanks, paint is sprayed onto metal rollers, the paint is transmitted from the metal rollers to the PU rollers, the paint on the PU rollers is scraped into a thin layer of paint film through scrapers, and finally the paint is coated on the box cover or the box body through the PU rollers. The automatic and simultaneous coating to the two relative edges of the square box cover or box body in the opening direction is realized; the production efficiency is greatly improved; the man-power is saved; the product varnishing is uniform; the consistency is good; and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of roll coating equipment for packaging boxes, and in particular relates to a UV primer roll coating device. Background technique [0002] With the rapid development of modern industry and the continuous improvement of people's living standards, people's demand for packaging boxes is increasing, especially for high-end goods. Packaging boxes have been widely used in electronics, food, beverages, alcohol, tea, cigarettes, etc. , medicine, health products, cosmetics, small household appliances, clothing, toys, sporting goods and other industries and fields. [0003] The existing high-grade solid wood square packaging boxes generally include a box cover and a box body. In order to improve the appearance of the packaging box, prolong the life of the packaging box, and make it better in corrosion resistance, a primer is also applied on the outside of the box cover and the box body. However, the coating of the pr...

[0003] The existing high-grade solid wood square packaging boxes generally include a box cover and a box body. In order to improve the appearance of the packaging box, prolong the life of the packaging box, and make it better in corrosion resistance, a primer is also applied on the outside of the box cover and the box body. However, the coating of the primer on the existing packaging box is generally done manually or semi-automatically, especially on the four sides of the box body of the square wooden packaging box and the opening direction of the lid, which can only be coated on one side at a time. Low efficiency and automation, waste of labor, and poor consistency and quality of manual coating
