The utility model relates to an automatic material shelf which comprises a feeding frame, a discharging frame, a feeding box, an automatic
cut-off
assembly and an automatic lifting and dumping
assembly, the feeding frame and the discharging frame are the same in structure and are both arranged on a
machine frame in an inclined angle mode, the feeding frame comprises at least two
layers, a rolling
pulley is arranged in the middle of the feeding frame, and the discharging frame and the feeding frame are dumped in the reverse direction. A rolling
pulley is arranged in the middle of the feeding frame, an automatic
cut-off
assembly is arranged above the feeding frame and comprises a
cut-off air cylinder, a cut-off lever, a fulcrum shaft and a cut-off plate, and the automatic lifting and dumping assembly comprises a feeding table, a guide rod and guide sleeve assembly, a jacking air cylinder, a dumping frame and a telescopic air cylinder. The automatic feeding device stably slides downwards under the assistance of the rolling
pulley, slides to the feeding table from the feeding frame and slides to the discharging frame after the inclination angle of the dumping frame is adjusted, the process of one-time product feeding and empty discharging is completed, the automatic feeding device is matched with the jacking air cylinder, switching feeding between two
layers or even multiple
layers of feeding frames is achieved, and the automatic feeding device is practical and convenient to use.
