Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing processing, in particular to a marking and coating device for hot-dip galvanizing workpiece processing. Background Art

[0002] Hot-dip galvanizing is an effective metal corrosion protection method, primarily used for the surface treatment of steel products. It involves immersing the steel in molten zinc, allowing the zinc layer to adhere to the steel surface, forming a zinc-iron alloy layer that prevents rust. The advantages of hot-dip galvanizing are strong zinc adhesion, excellent corrosion resistance, and a long service life. The hot-dip galvanizing process includes degreasing, pickling, washing, fluxing, drying, hot-dip plating, and cooling. Before hot-dip galvanizing, the workpiece surface needs to be marked to help workers distinguish between different workpieces and avoid confusion and processing errors.

[0003] Existing hot-dip galvanized workpiece marking and coating is usually done manually. Manual marking and coating requires long periods of standing and bending, which is labor-intensive and prone to fatigue. As a result, the marking and coating quality fluctuates, resulting in unclear and loose markings, making it difficult to distinguish workpieces, which affects subsequent workpiece processing.

[0004] To this end, the utility model provides a marking and coating device for hot-dip galvanizing workpiece processing. Utility Model Content
