[0031] When using, please refer to Figure 2 ; Adjust the spacing of the material forks 5 according to the crossbar specifications to ensure that the spacing of the material forks 5 meets the crossbar balance requirements; set the running speed of the chain 4 according to the product galvanizing process requirements to ensure that the galvanizing time of the crossbar meets the process requirements;

[0032] According to the zinc layer thickness requirement, adjust the required speed of the flywheel 14 and start it;

[0033] After the horizontal zinc throwing mechanism reaches the set speed, it starts and is placed into the jaws 6 of the material fork 5 through the cross bar of the feeding mechanism;

After the galvanizing reaction is completed and the crossbar is about to reach the zinc liquid, the scraping mechanism completes the scraping operation to ensure that there is no zinc ash and other impurities on the zinc liquid surface when the crossbar leaves the zinc liquid surface, thereby ensuring the surface quality of the crossbar;

[0035] After the cross bar leaves the liquid surface, it reaches the feed port of the shell 15, and after the end of the material lever 7 on the material fork 5 contacts the material guide and turning rack 16 and rotates, the cross bar is pried out from the tiger's mouth 6, and then the cross bar rolls to between the two flywheels 14 through the material guide and turning rack 16, and the external rotation driver drives the flywheel 14 to rotate, and the flywheel 14 drives the cross bar to rotate with the center of the cross bar as the center. After the cross bar rotates at a preset speed for a set time, the external rotation driver drives the material guide and turning rack 16 to rotate, so that the horizontal bar 23 rotates from a horizontal state to an inclined state, and the high-speed rotating cross bar rolls along the horizontal bar 23 to the discharge conveyor chain 22, and the discharge conveyor chain 22 transports the cross bar to the cooling and passivation station.
