Coating device for anti-corrosion layer of anti-corrosion prestressed twisted steel wire

One kind of anti-corrosion coating of prestressing strand coating apparatus comprising: a pretreatment, strand open, the center wire length, tightness adjustable side worked loose tight adjustment, painting, and other twisted strand closed complex part of the strand opening device settings before spreading mold 8 and diverging holding mold 12 center wire length 1 between tightness and tension adjusting means 9 by the damping cylinder reservoir line adjustment 13 composed of spindle storage spool thin cylinder, tension damping adjustment device consists of a tube-shaped support cylinder 21, the coupling plate 22, the bolt 23, the guide block 24, spring 25, the compact 26, the guide tube 27 composed of the worked loose tight side of said adjustment means by a connecting rod 11 and from 2 to 10 power transfer device is mounted on the connecting rod 10 composed of two adjacent force transfer device is mounted opposite direction. The device avoids the center wire transfer process from the guide wire wheel drive caused chaos during spraying and various pieces of twisted wire touching or failure, and to avoid wasting strand, and the operation is simple and convenient.
