The invention discloses a printing paper winding device which comprises a machine base (1). A workbench (2) is arranged on the machine base (1). Paper winding units (3) are arranged on the two sides of the workbench (2). One end of each paper winding unit (3) is connected with a cantilever (4). A drive motor (5), a driving wheel (6), a conveyor belt (7) and a driven wheel (8) are arranged on each cantilever (4). Each paper winding unit (3) comprises a rotary shaft (31), wherein one end of the rotary shaft (31) is connected with the corresponding driven wheel (8), and the other end of the rotary shaft (31) is connected with a fixed winding drum (32); and a movable winding drum (33) is connected to one end of the fixed winding drum (32), a fixed fastening shoe (34) is arranged on the outer surface of the fixed winding drum (32), and a movable fastening shoe (35) is arranged on the outer surface of the movable winding drum (33). The printing paper winding device not only can improve the clamping stability and prevent paper cores from deviating, but also has the advantages of being convenient to use and wide in application range.
