Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fan auxiliary manufacturing, in particular to an axial flow fan air duct spraying device. Background Art

[0002] The duct of an axial flow fan is generally a hollow cylindrical structure. In order to ensure the aesthetics and corrosion resistance of the duct, it is generally necessary to spray paint or anti-corrosion coatings on the inner and outer walls of the duct during duct processing. The outer wall of the duct is less difficult to spray. After the duct is fixed, workers can evenly spray along the outer wall; when spraying the inner wall, workers need to enter the duct. Paint or anti-corrosion materials are difficult to disperse on the inner wall, which seriously affects the health of workers. When spraying in a duct with a smaller inner diameter, workers have certain inconveniences in operation, which increases the difficulty of duct spraying. The existing utility model patent for an axial flow fan duct spraying device (publication number: CN220027512U) is provided with an adjustment slot on the mounting seat, which not only realizes the secondary adjustment of the distance between the spray gun and the inner wall of the duct, but also facilitates the adjustment of the inclination angle of the spray gun, further ensuring the effect of duct spraying.
