[0002] The steel bars used in some special working conditions need to be sprayed with coating to ensure the service life of the steel bar materials under special working conditions.

[0003] Existing steel bar surface layer spraying equipment generally includes two groups of spraying mechanisms. The first group of spraying mechanisms is used to spray the coating on the upper surface of the steel bar material, and then the steel bar material is turned over by manual turning, and then the second group of spraying mechanisms is used to spray the coating on the other side of the steel bar material. During the entire processing process, the steel bar needs to be turned over manually, and two-sided spraying is required to complete the coating spraying process, resulting in low overall processing efficiency. The most important thing is that after the coating is sprayed on the steel bar surface by combining upper and lower spraying, the uniformity of the coating thickness at the connection position is difficult to meet the design requirements, which can easily lead to waste of coating materials or cause the coating performance to fail to meet the design requirements.

[0004] Therefore, the research purpose of this invention is to design a steel bar surface layer spraying device that can complete the coating spraying operation on steel bar materials in one go, thereby effectively improving the processing efficiency; and can ensure the uniformity of coating spraying, thereby reducing the waste of coating materials and improving the coating performance.
