[0037] As shown in the drawings, Figure 3As shown, the coating roller 13 is provided with a feeding mechanism 100, the feeding mechanism 100 comprises a feeding roller 2 and a transfer plate 3 installed on the surface of the feeding roller 2, the number of the transfer plate 3 is two and the transfer plate 3 is symmetrically arranged along the axis of the feeding roller 2, the corner aluminum plate 9 is inserted on the surface of the transfer plate 3, the axis of the arc surface 91 of the corner aluminum plate 9 coincides with the axis of the feeding roller 2, the feeding roller 2 can be intermittently rotated to drive the transfer plate 3 and the corner aluminum plate 9 on the surface of the transfer plate 3 to rotate, so that the arc surface 91 of the corner aluminum plate 9 can be in contact with the coating roller 13, wherein the rotation directions of the coating roller 13 and the feeding roller 2 are consistent, so that Figure 3 For example, they are all rotated in the same direction as the pointer, and the driver for driving the feeding roller 2 is a prior art, so it is not described in this specification;

[0038] During the rotation of the feeding roller 2 and the coating roller 13, when the arc surface 91 of the corner aluminum plate 9 is in contact with the coating roller 13, the paint on the surface of the coating roller 13 can be transferred to the surface of the arc surface 91, realizing the roller coating of the surface of the arc surface 91.

Therefore, in the embodiment, by the roller coating device 1, not only can the roller coating of the ultraviolet resistant coating on the surface of the arc surface 91 of the corner aluminum plate 9 be realized to achieve the chemical blocking of ultraviolet rays, but also the fine concave-convex structure on the surface of the arc surface 91 of the corner aluminum plate 9 can be molded, the physical blocking of ultraviolet rays can be achieved by changing the interaction mechanism of light and the concave-convex surface, the anti-ultraviolet effect is greatly improved, and after molding, the roller coating can also greatly improve the bonding effect of the paint and the surface of the arc surface 91, reduce the probability of paint falling off during long-term outdoor use, and even if the anti-ultraviolet paint falls off during long-term use, the concave-convex structure on the surface can also play an anti-ultraviolet effect, thereby greatly improving the use performance of the corner aluminum plate 9.
