Device for manufacturing rebar rod with anti-corrosion film

The invention relates to a device for manufacturing a rebar rod with an anti-corrosion film and provides a device for manufacturing a rebar rod with an anti-corrosion film capable of obtaining inorganic particles reliably adsorbed on the resin film and with a long-term reliability. The device comprises a slit (43) along the conveying direction of a rebar rod (1), a unloading funnel (12) maintaining high-temperature state therein and capable of storing inorganic particles (3), a recycling funnel (53) maintaining high-temperature state therein and capable of storing inorganic particles (3), a supplying pipe (54) for supplying inorganic particles (3) stored in the recycling funnel (53) to the unloading funnel (12), and a recycling pipe (55) for returning inorganic particles (3) dropped from the unloading funnel (12) to the recycling funnel (53). The rebar rod (1) is conveyed to right under the slit (43) of the unloading funnel (12) while being rotated such that the inorganic particles (3) naturally dropped from
