Galvanising and epoxy-coating production line

A galvanising epoxy-coating production line, comprising a sandblasting machine (1), an assisting plating machine (2), a first air knife (3), a first pre-heater (4), a hot dip tank (5), a second air knife (6), a second pre-heater (7), an epoxy spray chamber (8), and a cooling chamber (9), arranged sequentially in order of workflow. The assisting plating machine (2), first air knife (3), first pre-heater (4), hot dip tank (5), second air knife (6), second pre-heater (7), and epoxy spray chamber (8) are provided with moving channels through which workpieces can pass; between the devices is arranged a rolling conveyer (10) on which the workpieces run. As the assisting plating machine (2), first air knife (3), first pre-heater (4), hot dip tank (5), second air knife (6), second pre-heater (7), and epoxy spray chamber (8) are provided with moving channels through which workpieces can pass, rebars can lie flat and pass one-by-one through the devices in the order of workflow; production efficiency is high, the electroplated rebars are long, and each device can be added or removed according to coating requirements; the production line is structurally compact, highly modular, and extension or improvement thereof is simple.
