Storage tape on-spool device of concentric type steel tape armoring machine

The invention discloses a storage tape on-spool device of concentric type steel tape armoring machine. The device comprises a storage tape mechanism and an on-spool mechanism arranged at one end of the storage tape mechanism; the tape storage mechanism comprises a movable support plate and a storage tape frame; edge beams are fixedly arranged at the place, close to two sides of a middle end, of the top of the storage tape frame along the length directions; moving tanks are arranged at opposite sides of two edge beams along the length direction, a plurality of rollers are uniformly arranged attwo sides of the bottom of the movable support plate; rollers at two sides of the bottom of the movable support plate are clamped into the moving tanks at two sides. The on-spool mechanism in the workcan drive a tape spool to move vertically and horizontally, the tape spool filled with the steel tape can be fed into the armoring machine, and the empty tape spool in the armoring machine can be taken out. The work is conven
