Angle steel multi-angle automatic spraying equipment and method thereof

The invention relates to the field of angle steel automatic spraying, in particular to angle steel multi-angle automatic spraying equipment and a method thereof. The angle steel multi-angle automatic spraying equipment comprises a supporting table, a linear conveying mechanism, a rotary spraying mechanism, an end supporting mechanism, a pressing mechanism, angle steel and two elastic supporting frames. According to the angle steel multi-angle automatic spraying equipment and the method thereof, the ends of the angle steel of various specifications can be pressed and fixed through the end supporting mechanism and the pressing mechanism, paint is sprayed to all positions of the angle steel through the rotary spraying mechanism and the linear conveying mechanism, and the angle steel does not need to be turned over by workers; the rotary spraying mechanism and the linear conveying mechanism work at the same time, a circle of paint is sprayed to the outer edge of the angle steel through a spray gun every time the
