When the paper is intermittently fed to the bottom of the leveling block 22 and the two sorting rollers 25, the feeding is stopped. At this time, by turning on the servo motor 28, the rotation of the turntable 21, and the sliding of the third plug 27 inside the lifting sleeve 7, the lifting sleeve 7 is made to slide back and forth on the top of the inner cavity of the second gantry 6, so that the connecting block 29 is used to push the lower pressure plate 9 and the sliding plate 12 to move synchronously. At this time, the sliding The plate 12 uses the U-shaped plate 16 to push the two sorting rollers 25 to contact the paper on the conveyor belt.
