[0004] Paper separation usually relies on two main methods: belt conveyors and suction cups. However, when using belt conveyors for paper separation, due to differences in paper material and friction coefficients, it often causes problems such as difficulty in separating paper smoothly or separating multiple sheets of paper at once. In contrast, the method of separating paper with suction cups can effectively avoid the problem of paper overlapping or missing, but its limitation is that it is difficult to adapt to paper of different sizes. Specifically, when paper is sucked by a suction cup, especially the corner parts of the paper, they often sag and bend due to gravity, which not only affects the flatness of the paper, but also may cause a series of problems in the subsequent conveying process, such as paper jamming, poor conveying, etc. SUMMARY
