Description

Square wood painting device {SQUARE WOODEN CLUB PAINTING APPARATUS}

The present invention relates to a lumber coating device, and more particularly, to prevent agglomeration of the water-based paint on the groove portion formed on the surface of the lumber, such as knots or rings, so that the water-based paint is evenly applied to the entire surface of the lumber. The present invention relates to a lumber coating device capable of improving quality.

In general, each timber is used for various purposes in various fields, for example, when building a concrete building, such as a building or a building including a building, it is used to build a formwork or support the formwork. It is also used for pillars, beams, legs, and the like of furniture including dressers, dressers, dressing tables, beds, dining tables, desks, chairs, and sofas. If a pattern is formed on each piece of furniture, it can increase the quality of the furniture. In addition, by forming a pattern on the lumber used for interiors or walls in addition to the above-described furniture lumber, it is possible to variously change the atmosphere of the interior space in which the lumber is installed.

As a method of forming a pattern on a lumber, there are a method of engraving an engraved or embossed pattern directly on the surface of the lumber, and then applying a transparent paint, and attaching a film on which various patterns are printed to the surface of the lumber. In the former case, the engraved or embossed pattern is directly engraved on the surface of the lumber, which gives a natural, elegant and beautiful feeling. On the other hand, in the latter case, various patterns and colors can be expressed because the printed film is pasted and has the advantage of easy operation.

However, the method of carving a pattern has a limitation of the pattern that can be expressed, the production is difficult and takes a lot of time to produce a disadvantage that the price is expensive. In addition, the method of pasting the film not only degrades the quality and value of the furniture, but also has the disadvantage that the film falls or is damaged when used for a long time.

In order to solve the above-mentioned problems, recently, knot horn wood with knots or rings formed on the surface of the lumber is widely used. These knotted wood can give a variety of feelings only by knots or rings that are formed on the surface of each wood without processing a separate pattern, which can enhance the dignity and value of furniture and express natural fashion and antique style.

However, knotted lumber is not smooth because the grooves are formed in the knot or ring part. In particular, deep grooves do not disappear even if the surface of the lumber is processed. Therefore, when the coating (including transparent paint) is applied to each knotted wood, the paint penetrates into the groove portion, and the paint aggregates due to the surface tension of the groove portion into which the paint penetrates. Therefore, the coating is not evenly applied to the entire surface of the knotty wood, there is a disadvantage that the quality is reduced.

The present invention is to solve the problems of the prior art described above to prevent the paint from agglomerating in the groove portion formed on the surface of the lumber, such as knots or rings, so that the water-based paint is evenly applied to the entire surface of the lumber The purpose is to provide a lumber coating device that can improve the quality.
