Description

TECHNICAL FIELD

[0002] MCM soft porcelain as a new type of environmental protection building material, its surface cover processing process has strict requirement to coating uniformity, gloss and weather resistance, traditional spraying process more uses single group of multiple spray head reciprocating spraying device, that is, while continuously moving the base plate along the conveying belt, spray gun frame reciprocates linearly perpendicular to the conveying direction, and the fan-shaped atomization track of spray head forms staggered coverage.

[0003] However, such traditional equipment has significant defects in practical application: when the spray gun group completes single reciprocating motion, due to the continuous movement of the base plate, adjacent spraying tracks form periodic overlapping "W" shaped coating distribution on the surface of the base plate, forming visible corrugated texture difference, especially in light color or high gloss surface treatment, such uneven thickness will cause obvious color difference and light reflection distortion, which seriously affects the appearance quality of the product.
