Gluing device and gluing method for large-size flower type reflective patterns

Abstract

The invention discloses a gluing device and gluing method for large-size flower type reflective patterns. The device comprises an upper pressure roller, a gravure upper rubber roller, a glue scraper and a glue supply mechanism for storing and providing glue. The glue scraper is located on one side of the gravure upper rubber roller, the edge of the scraping knife is in contact with the surface ofthe gravure upper rubber roller, the surface of the gravure upper rubber roller is provided with a flower-type pattern, and the gravure upper rubber roller is placed in the glue supply mechanism and is in contact with the glue in the glue supply mechanism The pattern is divided into a plurality of micro polygonal structure grooves or a combination of a number of micro polygonal structure grooves.The micro polygonal structure grooves are separated by micro thin walls, and the micro thin walls are connected with each other. The pattern fills the gap formed by the micro thin wall thickness through the leveling effect of the glue in the micro polygonal structure groove to realize the pattern. The pattern is transferred with glue. The method of gluing is also disclosed. The micro polygonal grooves are used and filled with micro thin walls to realize the leveling of glue and make the design pattern present completely.

Description

technical field [0001] The invention relates to the technical field of reflective material production, and more specifically relates to a gluing device and a gluing method for a large pattern fancy reflective pattern. Background technique [0002] The gravure topping roller used in the production process of reflective materials in the prior art is to make gluing pits by etching, because the patterns on the same roller surface are large and small, and when the roller is corroded, the pattern with a large area The etching depth is deep, and the etching depth of the pattern with a small area is shallow. The amount of glue applied to the deeply corroded place is large, and the amount of glue applied to the shallow place is small, which is reflected in the uneven thickness of the glue layer in the product, resulting in product quality problems. In order to ensure product quality, it is required to use the depth of the small pattern as a benchmark when making. The depth of such a...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem of uneven depth of the original gravure upper rubber roller in the production process; to solve the problem of glue overflow in the production process; to solve the problem of glue breaking in production; to solve the problem of design style change; and to solve the problem of pattern Design problem; to provide a large pattern with the same small pattern design, so that the deformation of the rubber roller in the gluing pit is negligible, so that the deformation of the blade of the squeegee in the gluing pit is very small , will not take away the glue in the gluing pit, fill the microstructure inside the design pattern to ensure that the design style remains unchanged, and the design pattern can be completely presented. The large-scale fancy reflective pattern gluing device and gluing method

[0009] In this large-scale fancy reflective pattern gluing device, there is a problem that the transferred fancy pattern is visually a pattern composed of N small dots by applying glue to the applicant's existing large-scale fancy reflective pattern. , the existing unconnected individual grooves are used as gluing grooves to form flower patterns, and the gluing flower patterns are divided or combined. The flower pattern can be divided. Design, that is, the flower pattern is designed to be divided into a number of micro-polygonal structural grooves through the segmentation method, or it can be designed through combination, that is, the flower pattern is designed to be formed by a combination of several micro-polygonal structural grooves, and The micro-polygonal structure grooves are blocked from each other by the micro-thin walls, and the micro-thin walls are connected to each other. During the glue transfer process, the flower pattern fills the thickness of the micro-thin walls through the leveling effect of the glue inside the micro-polygonal structure grooves. The gap formed to realize the full pattern glue transfer of flower patterns
