Description

Technical Field

[0001] This utility model relates to a coating equipment for a protective layer on the surface of galvanized aluminum-magnesium alloy steel wire, belonging to the field of galvanized aluminum-magnesium alloy steel wire processing technology. Background Technology

[0002] Galvanized aluminum-magnesium alloy steel wire is a new type of material with excellent performance, including strong corrosion resistance, high strength, and good toughness. It is widely used in bridge construction, automobile manufacturing, water conservancy projects, mine support, and other fields. Due to its unique coating composition, excellent corrosion resistance, and mechanical properties, it has been widely used in many fields and has promoted the technological progress and development of related industries. During the processing of galvanized aluminum-magnesium alloy steel wire, a protective layer is sprayed onto the surface of the galvanized aluminum-magnesium alloy steel wire to improve its performance.

[0003] Patent CN212418470U discloses a steel wire wear-resistant layer spraying device. This device starts a pressure pump, which feeds the coating material into the discharge pipe through the feed pipe, and finally sprays it evenly from the nozzle inside the annular pipe, thus coating the steel wire. A scraper can remove excess coating material from the steel wire, and the scraped coating material falls into the spraying box. Excess coating material sprayed from the nozzle also falls into the bottom of the spraying box, where the spraying box recycles and reuses the excess coating material. A heater can heat the coating material falling into the spraying box to prevent it from solidifying, thereby greatly saving materials and reducing production costs.

[0004] However, during the implementation of the above-mentioned patented technical solution, the protective layer on the surface of the galvanized aluminum-magnesium alloy steel wire is prone to uneven spraying. The existing galvanized aluminum-magnesium alloy steel wire uses a fixed nozzle to spray the protective layer onto the surface of the steel wire. When the nozzle is positioned at a fixed location, the angle of the nozzle to different positions on the surface of the steel wire is different, resulting in different spraying force and thickness of the coating on the surface of the steel wire, which leads to unevenness of the protective layer on the surface of the steel wire and affects the spraying quality.

[0005] Therefore, a protective coating spraying device for galvanized aluminum-magnesium alloy steel wire is proposed here. Utility Model Content

[0006] This invention proposes a spraying device for a protective layer on the surface of galvanized aluminum-magnesium alloy steel wire, in order to solve the problem that uneven spraying is easily caused when the protective layer on the surface of galvanized aluminum-magnesium alloy steel wire is sprayed using a nozzle at a fixed position in the prior art.

The heating plate heats the steel wire in the drying box, and at the same time, the hot air fan slowly blows hot air onto the surface of the steel wire, so that the coating on the surface of the steel wire dries quickly, which facilitates the subsequent winding of the steel wire.

[0026] Please refer to this carefully. Figure 1 A U-shaped frame 5 is fixed on the upper surface of the fixed plate 1. Four smoothing rollers 6 are rotatably connected to the inner wall of the U-shaped frame 5. The smoothing rollers 6 can assist in smoothing the galvanized aluminum-magnesium alloy steel wire 7 released from the winding roller 43.

[0027] In use, the following steps are taken: a take-up roller 43 with galvanized aluminum-magnesium alloy steel wire 7 wound on it is mounted on a rotating rod 42 near the smoothing roller 6. One end of the steel wire is then passed sequentially through the smoothing roller 6, positioning tube 214, spraying cylinder 22, and drying chamber 31, and fixed to the take-up roller 43 away from the smoothing roller 6. The four smoothing rollers 6 can compress and smooth the galvanized aluminum-magnesium alloy steel wire 7. Two second motors 41 operate, driving the steel wire conveying and controlling the operation of the first motor 211 and the pump 212. The pump 212 extracts the coating material from the fixed box 21 and delivers it to the spray nozzle 24 through the connecting hose 213 and the annular hollow frame 23. The spray nozzle 24 sprays the coating material onto the surface of the galvanized aluminum-magnesium alloy steel wire 7. Simultaneously, the first motor 211 operates, driving the rotating shaft 28 and guide roller 29 to rotate slowly. Under the sliding action of the guide roller 29 and the spherical sliding rod 210, the spherical sliding rod 210 and the rack 27 can move back and forth slowly. Under the meshing action of the rack 27 and the toothed ring 25, the spraying cylinder 22, the annular hollow frame 23 and the nozzle 24 can rotate back and forth. The rotation of the nozzle 24 allows the three nozzles 24 to completely cover the 360-degree surface of the galvanized aluminum-magnesium alloy steel wire 7, so that the protective layer is evenly sprayed on the surface of the steel wire. After spraying, the steel wire is conveyed to the drying box 31. Through the heating of the heating plate 33 and the slow blowing of hot air by the hot air blower 32, the coating on the surface of the steel wire is dried quickly. After drying, the steel wire is wound on the take-up roller 43 near the drying box 31. This device can make the coating thickness evenly adhere to the surface of the steel wire, ensuring the uniform spraying of the steel wire protective layer, thereby improving the quality of the galvanized aluminum-magnesium alloy steel wire protective layer.
