Description

Technical Field

[0001] The utility model belongs to the technical field of metal product spraying, in particular to a spraying device for processing highly weather-resistant metal products. Background Art

[0002] High-weather-resistant structural steel is atmospheric corrosion-resistant steel. It's made by adding small amounts of alloying elements, such as Cu, P, Cr, and Ni, to steel to form a protective layer on the metal substrate, enhancing the steel's weather resistance. This type of steel offers superior weather resistance to welded structural steel and is therefore known as high-weather-resistant structural steel. Composed of ordinary carbon steel with small amounts of corrosion-resistant elements like copper and nickel, it possesses the same high-quality steel properties as high-strength steel, including strength, ductility, formability, welding, abrasion resistance, high temperatures, and fatigue resistance. Its weather resistance is 2-8 times that of ordinary carbon steel, and its paintability is 1.5-10 times that of ordinary carbon steel. After fabrication, steel structures require a spray coating system for external painting. Existing spraying systems typically employ manual handheld spray guns, but this approach can lead to uneven application of paint on the exterior surfaces of metal pipes, resulting in poor results.

[0003] Publication number CN215354143U is a coating spraying device for the outer side of a metal pipe with uniform spraying effect. The device is provided with a support frame, a rotating shaft, a rotating seat, a supporting plate, an electric push rod, an inner lining arc plate, a driven pulley, a drive box, a motor, a driving pulley and a belt. When using the device, the metal pipe is first put on the outside of the inner lining arc plate, and then the electric push rod is started. The two electric push rods drive the two inner lining arc plates to move in the upward and downward directions respectively during operation to complete the fixation of the metal pipe. Then the motor is started and the rotating seat on the rotating shaft is driven by the drive pulley, the belt and the driven pulley to rotate, that is, the fixed metal pipe is driven to rotate. Finally, the sprayer is started to complete the painting of the outer side of the metal pipe, avoiding the trouble of manual spraying and achieving the purpose of uniform spraying effect of the device. However, it still has defects, such as residual paint will be left on the outer periphery after spraying, which is more troublesome to handle and easily leads to waste. Utility Model Content

[0027] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0028] After spraying, existing spray devices will leave paint residue on the periphery of the metal product. If left untreated, it will cause paint waste. The different thicknesses of paint on the surface of the metal product will also affect the quality. Natural filtration requires a long wait, and the process will also cause waste such as natural volatilization.

[0029] In order to solve the above problems, a spraying device capable of recycling excess paint is designed, but the device is mainly suitable for non-large metal products and the metal products are easy to fix or have through-holes, bayonets, etc.

The side door 2 has a handle for easy grasping and a fixed lock portion. The inside of the side door 2 is a structure with a protruding inner slope to facilitate the flow of paint.

[0032] See also Figures 1 to 4 In order to achieve uniform spraying, a variable speed motor 12 is installed at the top center of the spraying room 1. The driving end of the variable speed motor 12 passes through the spraying room 1 and is connected to a driving rod 13. The bottom bolt of the driving rod 13 is fixed with an averaging turntable 9. The bottom edge of the averaging turntable 9 is rotatably connected to a plurality of support rods 10. The support rods 10 are rotatably connected to the averaging turntable 9 through ring bearings.

[0037] How it works

[0038] When the highly weather-resistant spray coating device for metal products is used, the side door 2 is opened, the metal product is fixed on the fixing component 11, the pump body 6 is started for spraying, and the variable speed motor 12 is started at a slow speed to drive the rotating disk 9 to rotate and the support rod 10 to rotate;

[0039] While the support rod 10 rotates, the meshing design of the driven gear 14 and the driving gear 15 further realizes the self-rotation of the support rod 10, which makes the metal product rotate, further improving the uniform spraying effect;

[0040] After the spraying is completed, the speed of the variable speed motor 12 is gradually increased to swing the metal product to achieve the effect of paint stripping. After the paint stripping is completed, the speed is gradually reduced to stop.
