Secondly, after the waste is collected, it is usually necessary to recycle it. However, paper waste often needs to be crushed before recycling, which requires additional equipment to complete, which not only increases production costs, but also may prolong the entire recycling process, affecting production efficiency;

[0026] When the cutting of the printed matter is completed, since the flip plate 301 is located at the cutting knife 403, the flip plate 301 automatically rotates and opens under the action of the rotating motor 302, presenting a certain slope, so that the waste automatically slides into the waste box 101 through the slope. At the same time, since a vibration motor 303 is provided, the vibration motor 303 is started, and the waste can be caused to quickly slide into the inner cavity of the waste box 101 through the vibration effect.
