Leftover material compression device of die-cutting machine

The utility model relates to a die-cutting machine leftover material compression device which comprises a negative pressure funnel, the lower end of the negative pressure funnel is communicated with a pre-pressing cavity, a flashboard is transversely inserted into the bottom of the negative pressure funnel, the end of the flashboard is driven by a flashboard air cylinder to open and close a communication opening between the negative pressure funnel and the pre-pressing cavity, and a pre-pressing push plate is arranged in the pre-pressing cavity. One end of the pre-pressing push plate is driven by a pre-pressing air cylinder to transversely reciprocate in the pre-pressing cavity, the end, away from the pre-pressing air cylinder, of the pre-pressing cavity is communicated with a pressing cavity, a pressing plate is arranged in the pressing cavity, the top end of the pressing plate is driven by an electric cylinder to vertically reciprocate so as to compress leftover materials, and a discharging port is formed i
