[0004] To solve the above technical problems, the application provides a galvanizing flow line for steel caps of electric fittings, which comprises a ring-shaped track suspended from the top of a factory building for providing a galvanizing trajectory for the steel cap, a black piece loading ground track vehicle arranged at the starting position of the upper part of the track for transporting the steel cap to be galvanized, a white piece unloading ground track vehicle arranged at the end position of the upper part of the track for transporting the galvanized workpiece to the finished product area, a zinc pot arranged between the black piece loading ground track vehicle and the white piece unloading ground track vehicle on the upper part of the track for performing surface galvanizing operation on the steel cap, an electric hoist arranged on the upper part of the track and vertically movable along the track, and a hanger arranged at the end of the electric hoist for suspending a plurality of steel caps.

[0005] Since the flow line of the application is designed with a ring-shaped track, a black piece loading ground track vehicle, a white piece unloading ground track vehicle and a zinc pot, the flow line realizes full-automatic operation of the steel cap galvanizing by integrating multiple processes such as water washing, plating assisting, drying, galvanizing, zinc controlling, cooling and passivation, which not only improves the production efficiency and zinc layer quality, but also effectively reduces environmental pollution, meets the market demand for efficient and environmentally friendly galvanizing process, and solves the problems of low production efficiency, high labor intensity, inability to realize unmanned operation, and high-qualified automatic batch galvanizing operation of the existing manual galvanizing process.

[0006] Compared with the prior art, the technical scheme of the application has the following technical effects:

[0007] The flow line realizes full-automatic operation of the steel cap galvanizing, from loading to finished product unloading, without human intervention, greatly improving the production efficiency and safety.

[0008] By setting two water washing tanks and a plating assisting tank, the dirt on the surface of the steel cap can be effectively cleaned, and the surface of the steel cap is prevented from being oxidized, so as to make full preparation for forming a dense anticorrosive layer in the following step.

[0009] The zinc pot adopts natural gas as a heat source, so that the temperature of the zinc liquid can be accurately controlled, and the uniformity and density of the zinc-iron alloy anticorrosive layer are ensured; meanwhile, through the instantaneous reciprocating lifting operation of the electric hoist, the excess zinc liquid adhered to the surface of the steel cap can be effectively shaken off by means of the vibrating hook, so as to further control the thickness of the zinc layer.

[0010] The fixed cover is arranged above the plating assisting tank and the zinc pot, so that the toxic gas and zinc smoke generated in the process can be collected and treated, and the environmental pollution is reduced.

[0011] By setting the cooling tank and the passivation tank, the structural composition and gloss of the zinc-plated layer can be improved, and the wear resistance and service life thereof are improved. BRIEF DESCRIPTION OF DRAWINGS
