Galvanized epoxy coating production line

The invention discloses a galvanized epoxy coating production line, comprising a sand-blasting machine, a plating assisting machine, a first air knife, a first pre-heater, a hot dipping pool, a second air knife, a second pre-heater, an epoxy spray chamber and a cooling chamber, which are orderly arranged according to the technologic process, wherein the plating assisting machine, the first air knife, the first pre-heater, the hot dipping pool, the second air knife, the second pre-heater and the epoxy spray chamber are provided with mobile channels through which a work-piece passes; a rolling roller way for running the work-piece is arranged between every two devices. The plating assisting machine, the first air knife, the first pre-heater, the hot dipping pool, the second air knife, the second pre-heater and the epoxy spray chamber are provided with the mobile channels through which the work-piece passes, so that a rebar can lie flat and pass through the different devices one by one according to the procedure, the galvanized epoxy coating production line is high in production efficiency, and the galvanized rebar is long; the devices can be added or reduced according to the coating requirements, and the production line is compact in structure, high in modular degree, and easy to expand and improve.
