Cold-ironing type gold stamping mechanism

Abstract

A cold-ironing type gold stamping technology comprises the steps as follows: printing material with a layer of glue coated on pictures and texts and aluminum foil material are processed through rotary rolling combination, ultraviolet light box irradiation and rotary rolling stripping; an aluminum foil is imprinted on the corresponding pictures and the texts on the printing material due to the rolling combination and the sticking action of glue; and then room temperature cold-ironing operation is carried out under the ultraviolet light irradiation, and the printing material with the pictures and the texts achieving gold stamping effect is obtained finally. A cold-ironing type gold stamping mechanism of the cold-ironing type gold stamping technology adopts the structure as follows: an aluminum foil unreeling device and a scrap material winding are arranged at the upper part between a front wallboard and a rear wallboard, and a rotary rolling combination device and a rotary rolling stripping device are respectively arranged at the lower part between the front wallboard and the rear wallboard through a combination stripping wallboard; an ultraviolet light box is arranged between the rotary rolling combination device and the rotary rolling stripping device; and the combination stripping wallboard is connected with a simultaneous movable transmission device through a lower guide rail sliding block. The cold-ironing type gold stamping technology and the cold-ironing type gold stamping mechanism can accurately achieve the matching of cold stamping pressure time and cold stamping temperature, and improve the stamping fastness and the definition of a graphic profile, as well as the printing effect and the printing quality.

Description

technical field [0001] The invention relates to the field of printing and packaging, in particular to a bronzing mechanism applied to printing and packaging. Background technique [0002] With the improvement of the national economy and the development of the printing and packaging industry, the requirements for product packaging are: high-end, exquisite, environmentally friendly, and full of personalization. In the post-press processing of packaging products, hot stamping technology is loved by people because of its unique surface finishing effect, and it is used in high-end packaging such as cigarette labels, medicines, and cosmetics. Hot stamping process refers to the hot stamping production method of hot stamping, hot silver or other hot stamping materials (usually embodied on aluminum foil), which can be collectively referred to as hot stamping process. At present, the bronzing process is generally hot stamping, which heats the template to print the aluminum foil on th...

AI Technical Summary

Problems solved by technology

At present, the bronzing process is generally hot stamping, which heats the template to print the aluminum foil on the corresponding printing material. For different printing graphics, different templates need to be replaced. The input cost of the template is high, and it is difficult to accurately grasp. Hot stamping equipment and the matching between hot stamping time and hot stamping temperature, and many printing materials will shrink and deform when heated, which affects the hot stamping fastness and the clarity of graphic outlines, and affects the printing effect and printing quality of printed matter. quality
