Description

Embossing device for embossing round and round, paper printed matter and manufacturing method thereof

Technical Field

The invention relates to the technical field of embossing by rounding, and particularly discloses a embossing device by rounding embossing, a paper printed matter and a manufacturing method thereof.

Background

The convex-hitting technology, also called as concave-convex, relief, embossed pattern, etc., uses a group of concave-convex templates and convex templates with corresponding image-text in the form of yin and yang, places the printing stock between them, and presses out the relief-shaped concave-convex image-text by applying larger pressure. The embossing process is a very common process in post-printing processes and can emphasize the appearance of the local design.

Embossing is a common decorative packaging material processing technology, and is a technology for performing artistic processing on the surface of a decorative packaging material by deforming a pressure-bearing material (PVC, aluminum, wood, paper and the like) under the action of certain pressure and temperature by using a die with concave-convex grains.

In recent years, with the improvement of the requirements of people on appearance style and quality of commodity packaging, printing technology and packaging technology are greatly improved, and post-printing processing technology is developed vigorously.

However, the current printed matter basically adopts a single embossing or embossing technology during printing, and cannot meet the requirement of high-quality three-dimensional embossing and embossing products.

In this embodiment, the embossing texture unit and the embossing texture unit are both wavy lines.

As shown in fig. 2, the present application discloses a embossing device for embossing the paper printed matter. The round-pressing embossing device comprises a first roller 100 and a second roller 200 which are oppositely arranged, wherein a male die 110 is arranged on the first roller 100, a female die 210 is arranged on the second roller 200, and the female die 210 is in clearance fit with the male die 110 and used for printing paper 300 to pass through. In this embodiment, the gap between the female mold 210 and the male mold 110 is 0.05-0.1mm, which is smaller than the thickness of the printing paper 300.

The setting of roller among this circle of pressing circle embossing is hit protruding device is the same basically with prior art, and the difference lies in the design of terrace die and die, and is specific: the male mold 110 has a smooth mold surface, and the female mold 210 has a plurality of first texture units 211 which are arranged at intervals and are concave. The concave first texture unit 211 is arranged on the female die, the smooth die surface is arranged on the male die, no texture exists, the gap between the female die and the male die is smaller than the thickness of the printing paper 300, the printing paper 300 is extruded to be integrally thinned, and the concave first texture unit 211 on the female die is filled, so that the front surface (the surface facing to the female die) of the printing paper 300 generates convex texture, and the back surface (the surface facing to the male die) is kept to be a plane.

Further, at least one second protruding texture unit is arranged on the die surface of the male die 110, the width of one second texture unit is larger than that of at least one first texture unit 211, so that the area of the second texture unit, which acts on the paper printed matter, can cover the area of at least one first texture unit 211, which acts on the paper printed matter, and the texture of the embossed texture area 312 has the effects of embossing and embossing.
