[0034] In this embodiment, a galvanizing conveying assembly 3 is provided, and two telescopic cylinders 3-1 are provided on both sides of the outside of the galvanizing trough 1, and the output end of the telescopic cylinder 3-1 is connected to a side frame 3-2 installed in the side opening 2, and a main conveying roller 3-3, a clamping roller 3-4 and a lower pressure roller 3-5 are connected between the side frames 3-2, wherein the main conveying roller 3-3 is controlled to rotate by a motor to convey the strip steel in the galvanizing trough 1, and two cleaning rollers 3-6 are also provided, and the surface of the cleaning roller 3-6 is provided with a scraper bar 3-7 and a side scraper 3-8, and a driving motor 3-9 is provided on the outside of the side frame 3-2 and connected to one of the cleaning rollers 3-6, and transmission gears 3-10 are provided at the outer ends of the two cleaning rollers 3-6 and meshed with each other, and the two cleaning rollers 3-6 can rotate synchronously, and the scraper bar 3-7 and the side scraper 3-8 can scrape off the excess material on the surface of the strip steel during rotation. When cleaning is required, the telescopic cylinder 3-1 can be started to raise all the structures inside the side frame 3-2, which is more convenient for cleaning operations.

[0035] Furthermore, the drying processing component 4 includes an outer plate 4-1, which is fixed to the outer surface of the galvanizing tank 1, and an air hood 4-2 is installed on the outer plate 4-1, a drying fan 4-3 is installed on one side of the air hood 4-2, and a connecting pipe 4-4 is provided on one side of the air hood 4-2, and a pair of side plates 4-5 are provided on the surface of the outer plate 4-1, and a pair of rotating shafts 4-6 are rotatably connected between the side plates 4-5, and a plurality of supporting wheels 4-7 are installed on the rotating shafts 4-6.

[0045] When the strip needs to be galvanized, the strip is passed between the main conveying roller 3-3 and the pinching roller 3-4, around the bottom of the lower pressure roller 3-5, and then passed upward between another set of main conveying rollers 3-3 and the pinching roller 3-4, and then passed through the air hood 4-2 to start conveying. Galvanizing is carried out during the conveying process. When the strip moves upward, the excess material on the surface of the strip is cleaned by two synchronously rotating cleaning rollers 3-6, the scraper 3-7 on the surface and the side scrapers 3-8 on both sides, and then dried by the air hood 4-2 and the drying fan 4-3 and discharged outward. When cleaning is required, start the telescopic cylinder 3-1 to lift the side frame 3-2 upward as a whole.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
