[0002] Highway guardrails are an important part of road traffic safety facilities. By setting obstacles on the edge of the road, vehicles are prevented from running off the road, thereby reducing the occurrence of traffic accidents. Spray coating machine, also known as spray coating machine or electrostatic spray coating machine, is an industrial equipment that sprays powder coating onto the surface of the workpiece through electrostatic spraying technology. In the process of highway guardrail processing, the spray coating machine is mainly used to spray the surface material of the highway guardrail.

[0003] In the prior art, the authorization publication number "CN219664125U" discloses a "metal sheet spraying device"; it includes: a base, a workbench, a clamping mechanism and a spraying mechanism; a workbench that can rotate intermittently is fixedly arranged horizontally above the base, and a plurality of clamping mechanisms are arranged at equal intervals on the workbench, and a spraying mechanism for double-sided spraying of a workpiece rotated to the bottom and clamped in the clamping mechanism is vertically and liftably arranged above the base located next to the workbench, the spraying mechanism includes: a spraying pipe, a spray head and a spraying pump; spraying pipes that can move back and forth along the length direction of the workpiece are horizontally and liftably arranged on both sides of the workpiece, and a plurality of spray heads connected to their inner cavities are fixedly arranged at equal intervals on the facing surfaces of the two spraying pipes. The metal sheet spraying device overcomes the problem that the existing metal material surface can only be sprayed in a single manner, and the staff needs to turn the plate over to spray the other side, and the spraying operation cannot be performed continuously, which reduces the spraying efficiency.

[0004] The above-mentioned "metal plate spraying device" still has some disadvantages, for example: the existing highway guardrail plate has a wave-shaped shape, which is difficult to clamp during the spraying process. It is often placed flat on the surface of the sprayer for spraying, which will cause deviation and shaking during the spraying process. At the same time, the guardrail plate is long, and the position of the guardrail plate needs to be repeatedly adjusted during the spraying process, which is cumbersome;

[0005] For this reason, a highway guardrail plate spraying machine is proposed here to solve the above-mentioned problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a highway guardrail plate spraying machine to solve the problems mentioned in the background technology that deviation and shaking will occur during the spraying process, and at the same time, the guardrail plate is long and the position of the guardrail plate needs to be repeatedly adjusted during the spraying process.
