Description

Technical Field

[0001] The utility model relates to the technical field of section steel galvanizing equipment, in particular to a new type of hot-dip galvanizing machine for section steel. Background Art

[0002] Hot-dip galvanized materials are widely used in many industries such as industry, agriculture, construction, and transportation. They are used all over the country. Various types of angle steel are hot-dip galvanized. In my country, the method of manual discharging is still used. At present, the steel sections on the market are generally galvanized by galvanizing machines during hot-dip galvanizing production. The galvanizing machine is generally composed of zinc pot, dial rotating mechanism, frame assembly and other components. The chain conveyor sends the steel section to the dial of the dial rotating mechanism. The dial is fixed to the frame assembly on the upper part of the zinc pot through the rotating shaft. The motor drives the dial to rotate and drive the steel section to rotate in the zinc pot and complete the galvanizing. After the galvanizing of the steel section is completed, the steel section is manually pulled out of the zinc pot with a clamp and placed on the magnetic conveyor roller to complete the transportation of the galvanized steel section.

[0003] For example, the patent with application number 202322420852.3 discloses a fully automatic galvanizing machine for hot-dip galvanized angle steel and channel steel, including a zinc pot, a frame, multiple pressing assemblies, multiple picking and placing assemblies, four material hooks and a discharge assembly, wherein the zinc pot is arranged below the frame, the discharge assembly and multiple picking and placing assemblies are arranged on the frame, multiple pressing assemblies are respectively arranged on corresponding picking and placing assemblies, a feeding chain is arranged on the front side of the frame, the picking and placing assemblies include four driving modules, two material hooks and multiple guide rails, and multiple guide rails are fixedly mounted on the frame.

[0004] Although the above patent solves the problem of being able to realize automatic material taking and automatic pot unloading, thereby making production smoother, during the galvanizing process, before galvanizing, it is necessary to scrape the zinc ash on the surface of the zinc liquid to the end of the zinc pot, expose the mirror surface of the zinc liquid in the zinc pot, lower the hanger above the zinc pot, and immerse the steel section in the zinc pot until it is submerged; if the ash removal is not thorough, zinc ash will float on the surface of the zinc pot, which may easily cause quality defects such as missing plating, zinc thorns, and interlayers. The quality of galvanizing is uneven, it is difficult to guarantee the galvanizing effect, and the production efficiency is low and the zinc consumption is large. Utility Model Content
