A connecting frame 13 is installed at the lower end of the moving platform 11. The connecting frame 13 can grab the adjusting plate 7 at the notch 10. A galvanizing channel 14 is provided at the lower end of the galvanizing box 1. The lower end of the galvanizing channel 14 is installed in the galvanizing box 1 through a plurality of fixing rods 15. A fixing plate 16 is installed on the side of the galvanizing channel 14 away from the rotating cylinder 4. A circular opening 17 is opened on the fixing plate 16. The steel bar wire rod can pass through the circular opening 17. The adjusting plate 7 can move in the galvanizing channel 14 through the moving platform 11 and the connecting frame 13. The moving platform 11 can drive the rotating cylinder 4 to rotate in one direction through the transmission frame 18 when reciprocating. A circulating pump 19 is installed in the galvanizing box 1. A liquid inlet pipe 20 is installed at the inlet end of the circulating pump 19. The inlet end of the liquid inlet pipe 20 extends to the lower end of the galvanizing box 1. A liquid outlet pipe 21 is installed at the outlet end of the circulating pump 19. The outlet end of the liquid outlet pipe 21 extends to the upper end of the galvanizing channel 14 near the fixed plate 16. The process of galvanizing steel wire rods by this device is as follows: zinc blocks are added into the galvanizing box 1, and the inside of the galvanizing box 1 is heated by the heater 2 to melt it into zinc liquid. Under normal conditions, the moving platform 11 is driven to move by the driving frame 12, and the connecting frame 13 is moved to the notch 10. At this time, an adjusting plate 7 is located between the connecting frames 13. The moving platform 11 is driven to move back and forth by the driving frame 12, so that the moving platform 11 can drive the rotating cylinder 4 to rotate through the transmission frame 18. The annular limit plate 9 can limit the adjusting plate 7 to prevent the adjusting plate 7 from falling. When the adjusting plate 7 corresponding to the diameter of the steel bar rotates to the notch 10, the adjusting plate 7 is grabbed by the connecting frame 13, and then the moving platform 11, the connecting frame 13, and the adjusting plate 7 are driven by the driving frame 12 to move to the galvanizing channel 14, and the adjusting plate 7 is moved to the specified position according to the required galvanizing thickness, and the circulating pump 19 is started to pump the lower part of the galvanizing box 1 through the liquid inlet pipe 20. The zinc liquid is extracted from the end and then discharged into the galvanizing channel 14 through the liquid outlet pipe 21. As the zinc liquid level in the galvanizing channel 14 rises, the zinc liquid will gradually be discharged from the round mouth 17 and the circular through hole 8. After the zinc liquid is discharged from the circular through hole 8, since there is no obstruction at the rear side of the adjusting plate 7 in the galvanizing channel 14, the zinc liquid can quickly flow into the galvanizing box 1, thereby making the zinc liquid level between the fixed plate 16 and the adjusting plate 7 higher, and the zinc liquid level at the rear side of the adjusting plate 7 in the galvanizing channel 14 lower, which can facilitate the galvanizing of the steel bars. When it is necessary to adjust the thickness of the zinc layer, it is only necessary to change the position of the adjusting plate 7, and then straighten the steel bar wire rod so that it passes through the inlet and outlet 3, the round mouth 17, and the circular through hole 8, thereby facilitating the galvanizing of the steel bars. When galvanizing steel bars of different diameters, different adjusting plates 7 can be replaced, and the discharge speed of the zinc liquid can be conveniently controlled by the circular through holes 8 of different sizes on different adjusting plates 7.
