Equipment for coating wood board with oil paint

Abstract

The invention discloses equipment for coating a wood board with oil paint. The equipment comprises a lower roller and an upper roller, wherein the lower roller is used for conveying the wood board; the upper roller is positioned above the lower roller; a high-elasticity steel sheet tilting to the upper roller is arranged in front of the rotation direction of the upper roller; the upper surface of the steel sheet is a parabolic surface; the upper surface of the lower part of the steel sheet is close to the surface of the upper roller, and the closest distance is not smaller than the oil paint coating thickness of the wood board; the steel sheet is not shorter than the upper roller; a paint adding device for coating the oil paint is further arranged above the upper roller; the paint adding device is a spray pipe moving back and forth; the movement direction of the spray pipe is parallel to the direction of a roller shaft of the upper roller; a pipe orifice of the spray pipe is aligned with the surface of the upper roller. The equipment is simple in structure, and the thickness of the oil paint is uniform by virtue of the steel sheet used for uniformly scraping the oil paint; meanwhile, in order to prevent the surface of the upper roller from being probably scratched by the sharp edge of the steel sheet, the upper surface of the steel sheet is set as the parabolic surface, and the bulged surface of the steel sheet is close to the upper roller. The coating amount of the oil paint can be accurately controlled, knurls cannot be generated by reverse roll coating, and the phenomena of wrinkles and orange peels are avoided.

Description

technical field [0001] The invention relates to wood board processing machinery, in particular to wood board paint coating equipment. Background technique [0002] Wood floor processing usually requires painting, such as ordinary color paint and some protective paints. At present, most painting methods are sprayed manually, which is inefficient. Then there is a device that transfers the paint to the roller, and then rolls the paint from the surface of the board through the roller to coat the paint on the surface of the board. When the equipment applies the paint to the rollers, the coating amount of the paint on the rollers is uneven, so it is easy to cause the uneven paint surface of the plate. At the same time, due to the high viscosity of the paint itself, wrinkles and orange peels will occur after painting. For products that require high surface smoothness, it is necessary to use a sander to remove wrinkles, orange peels, etc. The next process can only be carried out a...

Problems solved by technology

When the equipment applies the paint to the roller, the coating amount of the paint on the roller is uneven, so it is easy to cause the paint surface of the board to be uneven

At the same time, due to the high viscosity of the paint itself, wrinkles and orange peels will occur after painting. For products that require high surface smoothness, it is necessary to use a sander to remove wrinkles, orange peels, etc. The next process can only be carried out after smoothing, which not only wastes man-hours, but also increases costs
