Problems solved by technology

Using this type of plate roller, although the effect of seamless plate seam can be achieved, the product quality is not satisfactory, which is specifically reflected in: (1) Due to the existence of a low temperature area, there is a gradual change from low temperature to high temperature on the surface of the molded working plate In the transition area, due to the temperature difference in the transition area, the overall effect of the molded material layout must have color difference and quality defects, and this transition area has a great impact on the brightness and hue of the product, and cannot meet the needs of products with high surface requirements; (2 ) There is a large temperature difference on the surface of the plate roller. During the molding process, the surface of the molded material is heated unevenly, resulting in inconsistent deformation, so that the molded material is deformed, which seriously affects the stability of product quality and the adaptability of post-processing; (3) It is necessary to configure two One molded plate roller and two sets of heaters will inevitably increase the consumption of energy and accessories, and increase the production cost of the product.

Embodiment Construction

[0032] The manufacturing method of the seamless mold embossing roller of the present embodiment comprises the following steps:

[0033] (1) Make a molded working plate 1 of a parallelogram;

[0034] In this step (1), the method for making the parallelogram-shaped molded working plate 1 is: reproduce the laser hologram text on the master plate through a laser engraving machine, and the master plate is copied into a molded working plate blank (usually Nickel plate); then use a plate cutter (the plate cutter should have a sharp knife edge and a neat incision) to cut the molded working plate blank to obtain a parallelogram molded working plate 1. Avoid burrs, nicks, etc. on the edges of the molded work when cutting. refer to figure 1 , in the parallelogram molded working version 1, the length of the first pair of opposite sides 11,12 is 1-2mm smaller than the outer circumference of the version roller body 2, and the second pair of opposite sides 13,14 is the same as the first pa...

Abstract

The invention relates to a production method of a plate-seam-free molding plate roller. The method comprises the following steps of (1) making a parallelogram molding work plate; (2) cleanly cleaningthe surface of the plate roller body; pasting the molding work plate onto the outer surface of the plate roller body; after the pasting of the molding work plate, the first pairs of opposite edges arepositioned in the peripheral direction of the plate roller body; in addition, a connecting seam is formed between the second pair of opposite edges; (3) the inside of the connecting seam is cleanly cleaned; the edge parts of the second pair of opposite edges of the molding work plate are downwards pressed to reach the downwards recessed state; (4) the connecting seam is filled with UV curing filling materials; a mother film is used, is pasted onto the UV curing filling material and is pressed; (5) the UV curing filling material is cured; after the curing is completed, the mother film is peeled away to obtain the plate-seam-free molding plate roller. The plate-seam-free molding product can be obtained by using the manufactured plate-seam-free molding plate roller through once molding; in addition, the plate roller can be integrally heated; the plate roller surface temperature difference is small; after the molding material is heated, the deformation is small; the product surface is smooth; the color difference is small; the brightness is stable.

Description

technical field [0001] The invention relates to laser holographic image-text embossing equipment, in particular to a method for manufacturing an embossing roll of a seamless mold. Background technique [0002] With the continuous improvement of domestic cigarette packaging materials refinement and efficiency, more and more cigarette packaging cardboards are constantly being revised, from single-page molded products to seamless molded products, and offset sheet-fed products are replaced by gravure rolls Tube products, product appearance requirements are constantly improving, and product profits are constantly being compressed, which has brought significant manufacturing pressure to cigarette packaging material manufacturers. [0003] At present, the packaging materials used on cigarette packs basically have laser graphics (laser holograms), and these laser graphics are formed by molding with a laser hologram molding device. The laser holographic text molding device generally...
