Aluminium-wire feeder of cylindrical thin-film packing sealer

The utility model relates to a copper wire feed apparatus used for cylindrical film package capper. The technological problem that the utility model solves is to provide a copper feed apparatus used for cylindrical film package capper with simple structure and free of adjusting feed length. The technical proposal includes a feed pinion, an angular magnification gear, a feed driving gear, a driven gear and an overrunning clutch. The pinion meshes with the big gear which is fixed to a frame; the overrunning clutch is arranged between the pinion and the driving axis which is arranged on the pendulum bar; the feed driving wheel is fixed to the driving axis; the driven wheel is positioned on the driven axis which is arranged on the pendulum bar; the edge of the driven wheel contacts the edge of the feed driving wheel with thread-clamping slot on corresponding edge. The apparatus is an ideal copper feed matching components for cylindrical film package cappers.
