Strip feeding device

The utility model provides a strip feeding device, comprising a frame [10], a cam-rocker mechanism and a drag plate [8] driven by the cam-rocker mechanism. The drag plate is mounted on the frame via a slide rail mechanism. In addition, a press pillar [19] is pivoted on a press pillar rack via a horizontal pivot perpendicular to the drag plate dragging direction. The press pillar rack is fixedly connected to the drag plate. The bottom end face of the press pillar is an inclined surface relative to the upper surface of the drag plate. Furthermore, the strip feeding device also comprises another cam-rocker mechanism for driving the press pillar, with a cam being connected on a linear cam [6] on a ram [5] of a punching device. Compared with the prior art, the strip feeding device of the utility model enables the separation of the press pillar from strips on the drag plate surface when the drag plate returns, thereby realizing no scraping of strips, eliminating friction damage of strips, the press pillar and the d
