Description

Technical Field

[0001] This utility model relates to a spraying device, specifically an anti-corrosion spraying device for surface treatment of metal products. Background Technology

[0002] To prevent metal products from corroding prematurely, protect the metal substrate, and extend their service life, appropriate spraying equipment must be used to apply anti-corrosion coating to the surface of metal products during the processing.

[0003] Existing anti-corrosion spraying devices for metal products have complex structures and unreasonable designs. During the anti-corrosion spraying process, existing devices require an input device to transport the metal product to the spraying device for spraying, and an output device to output it after spraying. Because two different devices are needed for transport, the conveying efficiency is low. Furthermore, neither the input nor output device can adjust the transport speed, and they cannot be stopped to maintain transport efficiency. Therefore, they cannot meet the spraying requirements of different metal products. In addition, the spray guns on existing anti-corrosion spraying devices are mostly fixed in position, allowing spraying only within a designated area, which easily leads to uneven spraying and a low yield rate. Therefore, the inventor has improved the structure of the anti-corrosion spraying device. Utility Model Content
