The present invention relates to a system and a method for dry-coating hanji, which is a type of traditional Korean paper handmade from mulberry trees. The system includes: a hanji input unit which inputs a hanji sheet to be used in a vacuum coating process using a UV coating material; a hanji preprocessing unit which removes moisture and foreign matter on both surfaces of the input hanji; a UV coating material spraying unit which sprays the UV coating material onto the surface of the cut hanji by using a spraying method; an air bubble removing unit which puts the hanji into a vacuum chamber and removes air bubbles on the surface of the hanji; and a UV lamp unit which emits UV rays onto the surface of the hanji to cure the UV coating material in the vacuum chamber. The present invention can remove the foreign matter and moisture in advance by using the preprocessing unit and use the spraying method to additionally execute a process to remove the bubbles on the hanji having the entire part of both surfaces evenly soaked in the UV coating material, thereby preparing the hanji while significantly improving the quality by completely removing the foreign matter and air bubbles.

Description

TECHNICAL FIELD [0001] The present invention relates to a dry coating system and a method thereof,

More particularly, the present invention relates to a dry coating system and a method of the same, and more particularly, to a method and apparatus for coating a UV coating The present invention relates to a dry coating system and a method for the functionalized paper, which is capable of producing a functional paper capable of being used in various products by removing air bubbles from a sufficiently wet curable liquid (UV curable liquid).

    Our unique hanjang is made of mulberry tree, and it has the advantage that it has a hard fiber, a good quality and a smooth surface. It also has a soft touch, excellent breathability and warmth, and unlike other paper, it has a unique and soft effect. Therefore, Hanja, which has the characteristics as described above, has traditionally been used to make fan, flower paper, paper, paper, ornaments.

However, in order to make a variety of products using Korean paper, it is necessary to increase the durability of Korean paper while taking advantage of the advantages of Korean paper. When coated with Korean paper, it is possible to obtain coated paper that can be used for such purposes. In other words, it is necessary to improve the durability of Korean paper by curing the paper so that it can be utilized as a product while maintaining the material and shape of Korean paper as much as possible.

However, despite the many advantages described above, there is a fatal disadvantage that foreign matter adheres to the surface and is weak to the water. Therefore, even in the vacuum coating process, foreign matter existing on the surface of Korean paper can not be effectively removed, or when the coating process is carried out in the state of water, there is a problem that the advantages of Korean paper can not be fully utilized.

In addition, even when foreign matter and moisture are removed from the surface of Korean paper, a problem arises in that a certain solution is sprayed on Korean paper and caking of the solution causes bubbles to form on the surface of Korean paper, thereby failing to function as a functional paper. If the problem of bubbling can not be solved, the value of the product as a product such as a bag or a wrapping paper is lowered even if the product is subjected to a separate coating process.

Therefore, it is necessary to develop a technique to solve the problems occurring in the coating process of the Korean paper.

First, a desired one-side coated fabric is applied to the vacuum coating system 100 (S110).

Thereafter, foreign substances and moisture are removed from the one or both sides of the paper through the pre-processing unit (S120).

Thereafter, the UV paint is uniformly sprayed onto the surface of the paper through the UV paint spraying unit using the spraying method (S130).

Thereafter, the paper coated with the UV paint is introduced into a vacuum chamber (S140).

Then, the air bubbles on the surface of the paper are removed in the vacuum chamber (S150).

Then, the ultraviolet light source is irradiated on the surface of the paper in the vacuum chamber to cure the UV coating (S160).

Finally, coated paper is taken out from the vacuum chamber (S170).

For reference, the step of cutting the Korean paper into a desired length may be performed at any stage before the paper is inserted into the vacuum chamber 50.

According to such a dry paper coating method, it is possible to make a flawless functional paper which can be applied to a real product while maintaining the texture of the paper paper.
