Abstract

The present invention relates to a mirror shaping device for the surface of the wood grain plate material, while applying a UV-paint (ultra-violet painting unit) on the surface of the wood grain pattern plate, spreading the transparent release film on top of it, and then irradiated with UV light to remove the release film Effort to minimize the cost burden by mass production of high-grade plate to form the mirror surface on the surface of wood grain pattern plate by simply performing the task of obtaining the mirror surface.

Description

Surface shaping apparatus for the surface of wood grain plated {Surface of a mirror formed wheel equipment}

The present invention applies UV-curing paint (UV paint) to the surface of wood chips (MDF) on which wood chips are formed of medium-density molding, and spreads a transparent release film on it, and applies ultraviolet light (Ultra-Violetray). It is related with the mirror surface shaping | molding apparatus of the surface of a grain-patterned board material for peeling a release film after irradiating and hardening and obtaining a mirror surface.

The above-mentioned wood grain pattern plate is used as a high-grade plate by shaping the surface into a mirror surface. Conventionally, the surface of the wood grain plate sheet is cured by irradiating UV light on the UV paint layer coated with the UV coating several times by a roller coating method. Although the coating layer was obtained, the surface of the coating layer was not a mirror surface due to the characteristics of the roller coating, but appeared as a rough surface (orange peeling surface shape). Since it was obtained by spraying the mirror surface, it was difficult to mass-produce due to high cost and time-consuming process as well as difficulty in the work process that goes through several processes, and there was a big problem of economic loss of high cost burden.

In addition, it is possible to apply Homica instead of UV paint and harden it for 5 to 6 hours to obtain a mirror surface. In this case, however, hardening takes a long time. The present invention has been devised to solve these various problems, because the economic loss of high cost burden is large.

UV coating is applied to the surface of the wood grain plate, and the transparent release film is laid on it, and the UV light is transmitted and cured. Then, the release film is peeled off to obtain a mirror surface. Minimization of high cost burden

On the vacuum table (1), a UV paint coating unit (8) consisting of a primary UV paint coating roller (5), a secondary UV paint coating roller (6), and a release film covering roller (7) and an ultraviolet light transmitting portion (9) When the UV paint application unit 8 and the UV light transmitting unit 9 move forward and backward together, the UV paint layer 12 is fixed on the surface of the wood grain plate 2 placed on the vacuum table 1. Apply the thickness and lay the release film 4 thereon and irradiate UV light thereon to cure it, and after the UV coating application unit 8 moves backward, the release film 4 is removed to form a mirror UV coating layer. It was.

And the primary UV paint amount buried on the surface of the primary UV paint film coating roller (5) is the primary UV paint supplied from the primary UV paint supply nozzle (5a) by the primary UV paint flow rate control roller (5b) The secondary UV paint applied to the secondary UV paint film application roller (6) is controlled by the secondary UV paint supplied from the secondary UV paint supply nozzle (6a). The amount of UV paint controlled by the release film guide roller (7a) and buried on the release film (4) surface moving toward the release film covering roller (7) through the release film guide roller (7a) is supplied by the UV paint supply roller (10) The thickness of the UV paint layer 12 is adjusted in the paint thickness adjusting knife 11, and the release film 4 is wound around the release film roll 13 to be unwinded and wound with the forward and backward movement of the UV paint application part 8. The small diameter guide roller in the release film guide roller 7a has a small amount of hardened paint residue on the surface of the release film. The release film, which is separated by bending while passing through the diameter roller surface, is separated through the intake pipe 7b according to the intake force and repeatedly used the transparent release film 4, is cut out from the release film roll 13, and used. The end 4a of the film 4 is fixed to one side of the vacuum table 1, and the first and second UV paint film coating rollers 5 and 6 and the first and second UV paint flow rate adjusting rollers 5b and 6b ) And release film covering rollers (7) and UV paint thickness adjusting knife (11) to move up and down by a hydraulic device (not shown) to control the distance and the amount of UV paint amount of the wood grain plate (2) surface Their organic operation is controlled by the central processing unit of the automatic program.

In addition, bubbles generated in the U-V paint film applied primarily by the surface of the primary U-V paint film coating roller 5 are removed by the surface of the secondary U-V paint film roller 6 to form a smooth U-V paint layer.

In the ultraviolet light transmitting unit 9, heat generated in the ultraviolet light 9a is exhausted from the heat sink 9b through the exhaust pipe 9c and exhausted by the fan 9d.

The present invention has a UV coating on the surface of the wood grain plate (2) when the UV paint coating unit (8) and the UV light transmitting unit (9) is advanced on the wood grain plate (2) placed on the vacuum table (1) 3) the release film 4 is laid thereon and ultraviolet rays are transmitted to cure the UV paint layer 12, and then the release film 4 is detached by the reverse of the UV paint application unit 8, and the mirror UV paint Since the layer 12 is formed, the fine grained wood plate 2 having a mirror surface can be mass produced in a simple manner.

Since the mirror surface U-V coating layer can be easily formed on the surface of the wood grain plate, it is possible to mass-produce high quality plate and reduce the economic cost of high cost.
