The invention discloses a coiled-material feeding mechanism of an antenna terminal automatic laminating machine. The coiled-material feeding mechanism of the antenna terminal automatic laminating machine comprises a coiled-material feeding apparatus, a coiled-material correcting apparatus, a coiled-material cutting and bending apparatus, a coiled-material stamping apparatus and a waste material cutting and collecting apparatus, wherein the coiled-material feeding apparatus and the coiled-material correcting apparatus are arranged on a rack in sequence; the coiled-material cutting and bending apparatus is positioned on the rack above the coiled-material correcting apparatus; the coiled-material stamping apparatus is positioned on the rack below the coiled-material correcting apparatus; the coiled-material feeding apparatus comprises a material tray, a stepped shaft, a locking ring and a flange holder; the material tray passes through the stepped shaft to be fixed on the stepped shaft through the locking ring; and the two ends of the stepped shaft are fixed on the rack through the flange holder. By adoption of the mode, the coiled-material feeding mechanism is convenient to operate, long in service life, good in bending and stamping effect, low in workpiece abrasion, and capable of improving the production efficiency and lowering the production cost.
