Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically, to an adjustable conveying mechanism for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is a highly effective corrosion protection technology for steel materials. Simply put, it involves immersing cleaned steel parts in molten zinc at approximately 500°C, causing a zinc layer to adhere to the surface, thus achieving corrosion protection. Zinc is chemically more reactive than iron. When the coating is damaged and the steel is exposed, micro-batteries form in a humid environment, consuming zinc to protect the steel. Pre-treated and dried workpieces are immersed in molten zinc at approximately 445-500°C. Iron and zinc react at high temperatures to form a firmly bonded zinc-iron alloy layer. The most common hot-dip galvanizing conveyor equipment currently available is the conveyor belt. However, existing conveyor belts have certain problems and defects that can affect the use of the equipment.

[0003] Firstly, when the equipment is being transported, it often uses a conveyor belt with hooks for transport, which results in a relatively fixed transport method, poor adjustability, and consequently, poor practicality.

[0004] Secondly, the equipment is highly integrated during transportation, which requires complete disassembly and reassembly for maintenance. This results in a low degree of modularity and consequently, lower work efficiency.

[0005] Furthermore, the manual operation of the equipment involves cumbersome steps, resulting in a low level of automation. Summary of the Invention
