A production system and method for a seamless mold embossing roll

Abstract

The invention discloses a printing seam-free mold pressing printing roller manufacturing system and method. The printing seam-free mold pressing printing roller manufacturing system comprises a PET (polyethylene terephthalate) mold pressing printing reproducing device and a PET mold pressing printing transfer printing seam-free printing roller device. The PET mold pressing printing reproducing device comprises a rack, wherein a compression roller mechanism is arranged on the rack; a first PET leading film is arranged in the compression roller mechanism and is connected to a first feeding mechanism. The PET mold pressing printing transfer printing seam-free printing roller device comprises a UV (Ultraviolet) lamp, wherein a printing roller to be machined is rotatably arranged in front of the UV lamp; a mold pressing device is arranged on the printing roller to be machined; a second PET leading film is arranged between the printing roller to be machined and the mold pressing device and is connected to a second feeding mechanism; the PET film pressure plate transfer printing seam-free printing roller device is additionally provided with a matting film, so that the UV gloss oil of a shading area cannot be cured, thereby preventing the veins of overlapping lines from occurring on the printing roller through mold pressing and achieving the effect of hiding printing seams; and the printing seam-free printing roller manufactured by using a single roller can reduce generation of interference veins and improves the quality of printing roller patterns.

Description

technical field [0001] The invention relates to the technical field of mold embossing, in particular to a system and method for making a mold embossing roll without a plate gap. Background technique [0002] The current laser holography uses a flat sheet plate to be pasted on the plate roll for molding. The nickel plate is at the place where the plate roll turns around and the head and tail are handed over. Because of the thickness of the nickel plate, the diameter of the plate roll, the nickel plate cutting and human operation and other errors , will cause the molded product to have an obviously ugly seam. Although there is already a device that uses two sets of plate rollers to repeatedly mold to make a hidden plate gap, but the two embossings have shadows formed by the temperature difference at the position of the plate gap, and the brightness is reduced due to the two embossings, and some layouts will have double embossing.

[0002] The current laser holography uses a flat sheet plate to be pasted on the plate roll for molding. The nickel plate is at the place where the plate roll rotates around the head and tail, because of the thickness of the nickel plate, the diameter of the plate roll, the nickel plate cutting and human operation. , will cause molded products to have a very unsightly version seam

Although there is already a device that uses two sets of plate rollers to repeatedly mold to make a hidden plate gap, but the two embossings have shadows formed at the position of the plate seam due to temperature differences, and the brightness is reduced due to the two embossings, and some layouts will appear double embossed. Moiré interference patterns formed by printing, or the pattern discontinuity caused by the error of the two embossings, and the double embossing also doubles the heating mechanism, which wastes power resources. In addition, because the two sets of molded plate rollers have heating areas and In the cold zone, the effect of thermocouple will make the wide-width plate roll easy to bend and deform, resulting in shortened life of the plate roll and the inability to produce ultra-wide seamless plate pressing, so a single-roll seamless plate roll is needed to solve these problems
