The utility model discloses a paper leveling component of a paper blocking device of a printing
machine, which belongs to the technical field of printing machines and comprises a base, a
workbench is fixedly arranged at the top of the base, a winding drum is fixed in the middle of the
workbench, the bottom of the winding drum is attached to the base, the top end of the winding drum protrudes above the
workbench, and a feeding and discharging port is formed in the top of the winding drum. The bottom end of the feeding and discharging port is parallel to the plane of the workbench, the other end of the feeding and discharging port is located above the workbench, a rotating roller is rotationally installed between the two ends of the winding drum, and a driving motor is rotationally arranged on the rotating roller. According to the utility model, through the arrangement of the reverse winding mechanism consisting of the winding drum, the material inlet / outlet, the rotating roller, the guide roller, the conveying belt and the guide plate on the workbench, paper which is bent upwards passes through the interior of the reverse winding mechanism, reverse winding is directly carried out by adopting an
extrusion mode, heating is not needed, more energy is saved in use, continuous
extrusion can be carried out in the conveying process, and the production efficiency is improved. And the flattening effect is guaranteed, and the practicability is higher.
