Chopping machine with paper separation and feeding mechanisms

The utility model relates to a chopping machine with paper separation and feeding mechanisms. The chopping machine is provided with a cutter element for destroying articles such as paper, and a separation mechanism for separating at least one piece of paper from an overlaid body in a tray, wherein the separation mechanism is started by rotation of the cutter element; in one embodiment, the separation mechanism is a screw mechanism, the screw mechanism which is formed by coils is inserted in a paper stack and is used for receiving separated paper from the paper stack among gaps of the screw mechanism along with the rotation of the screw mechanism, and the separated paper can fall into the chipping mechanism under the gravity action; optionally, a paper feeding mechanism can feed the separated paper into the cutter element; the tray can comprise an edge for guiding the separated paper to the cutter element; one or more staple picking and bearing mechanisms can be arranged for separating stapled paper.
