Description

[Detailed description of the invention] This invention relates to a rock wool board coating device for painting the surface of rock wool boards. To provide a rock wool board coating device capable of imparting a certain appearance to the surface of a rock wool board, and reducing the cost of painting by eliminating waste of paint.

Conventionally, rock wool boards have been painted in a single uniform color, which has caused problems such as a monotonous appearance with no depth and lack of decorative qualities as a building material.

The present invention has been devised in view of the above points, and will be described in detail below based on the embodiments shown in the figures. The main roller 1 is disposed over the entire width direction of the rock wool board 2 in contact with the upper surface of the rock wool board 2 that is conveyed in one direction, and the sub roller 3, which has approximately the same length as the main roller 1, runs around the periphery of the main roller 1. A paint mixing section 4 is formed between the main roller 1 and the main roller 1 by rolling thereon. A paint discharging port 5 is provided above the approximately central portion and both ends of the paint mixing section 4 in the longitudinal direction, respectively.
The central paint discharge port 5 is connected via a pipe 9 to a first tank 8 provided below the end of the paint mixing section 4, and the paint in the first tank 8 is supplied to a pump 10. The paint is supplied to the paint mixing section 4 from the paint discharging port 5, and the discharging ports 6 and 7 on both sides are formed at the lower ends of a second tank 11 and a third tank 12 provided above both ends of the paint mixing section 4. The second tank 11 is filled with dark paint that has the same hue as the paint in the first tank 8 but has a different degree of saturation, and the third tank 12 is filled with a dark paint that has the same hue as the paint in the first tank 8. The main roller 1 is filled with thin paints of different saturation levels, and the paint flowing out from each paint discharge port 5, 6, and 7 coats the surface of the rock wool board 2 with unevenness, such as a wood grain pattern with varying shading. This will be carried out at Here, the flow rate of the paint from the second tank 11 and the third tank 12 is adjusted so that when both are oriented, the paint has the same color as the paint in the first tank 8.
The paint that overflows from the end of the tank is transferred to the first tank 8.
It is now being collected.

In the present invention, with the above-mentioned configuration, dark and light colored paints having the same hue but different saturation levels are discharged from the paint discharging ports corresponding to both longitudinal ends of the paint mixing section, and the paint discharging ports at the center. Since the above-mentioned dark and light colored paint is discharged, each of the three paint discharges discharges paint of a different density, so the surface of the rock wool board has variations like a wood grain pattern with varying shading. Moreover, the paint discharged from the central paint discharge port is obtained by mixing the paint discharged from the paint discharge ports on both sides, and the mixed paint has a dark color. The color is intermediate between light and light colors, and it has the advantage that the above-mentioned change in color shading can be obtained, and that the paint left over from painting can be used effectively without wasting it, resulting in lower painting costs.

Claims (1)

[Scope of utility model registration request] A paint mixing section is formed between the main roller that rolls along the surface of the supplied rock wool board and the main roller that rolls in contact with the peripheral surface of the main roller at a position away from the rock wool board. It is composed of an auxiliary roller and paint discharging ports arranged approximately at the center in the longitudinal direction of the paint mixing section and above both ends, and the paint discharging ports corresponding to both longitudinal ends of the paint mixing section have the same hue. Dark and light color paints with different saturation levels are discharged, and the dark and light color paints are mixed into the central paint discharge port and the paint collected from the end of the paint mixing section is discharged.
