Overprinting method for performing secondary printing on cold-ironing film

Abstract

The invention discloses an overprinting method for performing secondary printing on a cold-ironing film. According to the overprinting method for performing secondary printing on the cold-ironing film, an equipment shell, a first gluing device, a first printing device, a first drying device, a first separation device, a second gluing device, a second printing device, a second drying device, a second separation device, a material receiving device and an emptying device are provided; the emptying device is arranged on one side of the internal part of the equipment shell; the emptying device is fixedly connected with the equipment shell; the first gluing device is arranged on one side of the emptying device; and the first gluing device is fixedly connected with the equipment shell. Accordingto the overprinting method for performing secondary printing on the cold-ironing film, overprinting of secondary printing is directly connected with one side printing to form an automatic production line; after positioning of the secondary printing is adjusted simply, products can be directly produced, the carrying time of materials after primary printing is saved, the positioning adjusting time of the secondary printing after primary printing is saved, the labor force is greatly reduced and the production efficiency of the products is improved.

Description

Technical field [0001] The invention relates to the technical field of cold foil printing, in particular to an overprinting method for secondary printing on a cold foil film. Background technique [0002] Cold stamping is a kind of printing technology. Special glue (ink) is used to adhere cold stamping anodized aluminum to the surface of the substrate except the base layer to achieve the effect of hot stamping. The essence of hot stamping is transfer printing. The process of transferring the pattern on aluminum to the substrate through the action of heat and pressure. When the printing plate heats up to a certain extent with the attached electric heating plate, it is embossed through the anodized aluminum film and paper, using the temperature and pressure. Function to transfer the adhesive layer, metal aluminum layer and color layer attached to the polyester film to the paper. [0003] The existing cold foil printing has to perform a second printing after one printing, which means...

AI Technical Summary

Problems solved by technology

[0003] In the existing cold stamping printing, after the first printing, the second printing is performed, that is, the product of the first printing is placed in the discharge device again, and the process of printing on one side is repeated again, but the second printing requires new positioning, and the positioning is cumbersome , the printing method is too troublesome, and in the process of printing glue, the glue is in a static state, the glue is easy to condense and precipitate, which is not convenient for printing glue, and the scraper used when scraping the anilox roller, for different products It is necessary to adjust different glue thicknesses. The scraper is used for a long time, and a layer of glue is formed on the surface, which needs to be cleaned regularly. However, the existing disassembly methods are mostly nut disassembly, which is cumbersome and time-consuming. Therefore, we propose a cold perm film The overprinting method of the last two printings
