[0002] Steel structures are widely used in the construction field. In order to increase the corrosion resistance of steel structures in buildings, it is necessary to spray anti-corrosion coatings on steel structures to ensure that steel structures can resist the erosion of various harsh environments in the future. Anti-corrosion coatings can not only effectively prevent steel structures from reducing their load-bearing capacity and service life due to rust, but also improve the overall aesthetics of the structure.

[0003] Existing technology uses a conveyor roller to transport steel structure workpieces to be coated. When the workpiece passes through the spraying chamber arranged on the conveyor roller, the anti-corrosion coating is applied to the workpiece by the spraying mechanism inside the spraying chamber.

When there is dust or impurities on the surface of steel structures, it will affect the spraying effect and easily lead to problems such as coating peeling, blistering and falling off during the later use of steel structures. Therefore, a special spraying equipment for anti-corrosion coating of steel structures is proposed to solve the above problems. Utility Model Content

The setting of the fixing frame 307 and the electric heating wire 308 can heat the blown air, thereby further improving the curing efficiency of the coating.

[0025] Working principle: During the conveying of the steel structure by the roller conveyor 1, the first motor 202 is started to drive the first brush roller 203 to rotate. The first brush roller 203 drives the second brush roller 204 to rotate through the double-groove synchronous wheel 205, the first synchronous wheel 206 and the first synchronous belt 207. The first brush roller 203 and the second brush roller 204 perform roller cleaning on the surface of the steel structure that needs to be sprayed, which can perform double cleaning on the surface of the steel structure during the movement, removing the dust and impurities adhering to the surface of the steel structure. The position of the limit frame 15 can be adjusted by starting the cylinder 14, so that the limit rollers 16 on the two limit frames 15 can limit the conveying of the steel structure on both sides during the conveying process, so as to avoid the problem of conveying deviation of the steel structure. When the steel structure workpiece passes under the spray head 9, the paint tank 11 fills the spray head 9 with liquid through the connecting pipe 12 and the corrugated pipe 13, so that... The coating is sprayed onto the steel structure surface by the spray nozzle 9. Starting the second motor 5 drives the lead screw 6 to rotate, allowing the moving table 7 to move along the guide rod 8. When the contact plates 10 on both sides of the bottom of the moving table 7 touch the corresponding contact switches 18, the contact switches 18 transmit a sensing signal to the controller. The controller controls the second motor 5 to reverse, thereby realizing the automatic reciprocating motion of the moving table 7. When the steel structure workpiece is finished being sprayed and is conveyed out of the spray frame 4, the rotation of the first brush roller 203 drives the rotating shaft 302 to rotate through the double-groove synchronous wheel 205, the second synchronous wheel 304, and the second synchronous belt 305. This causes the fan blades 303 to fan the coating on the steel structure surface. With the help of the heating wire 308, the coating can be dried with hot air, improving the curing efficiency of the coating. This achieves the integration of cleaning, spraying, and drying of the steel structure workpiece, improving the efficiency of steel structure spraying processing.

[0026] It is worth noting that: In this embodiment, a controller (not shown in the figure) is also installed inside the spraying rack 4. The controller is specifically a programmable logic controller (PLC). The second motor 5 and the two contact switches 18 are all electrically connected to the controller. The electrical equipment in this embodiment are all commonly used equipment in the prior art. The models used can be customized according to actual usage requirements. In addition, the power supply interface of the electrical equipment in this embodiment is connected to the power supply system through a switch (not shown in the figure) and a wire (not shown in the figure) to realize its control. The circuits and controls involved are all prior art and are known in the current field. They will not be described in detail here.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
