A paper winding machine, comprising:

• a frame body;
• a winding roller installed on the frame body in a horizontal direction, the winding roller defining opposing, first and second ends;
• wherein the winding roller defines a through groove in an outer wall thereof, the through groove extending in a length direction of the winding roller;
• first and second winding roller adjusting mechanisms installed at the first and second ends, respectively, and to an inside of, the winding roller;
• a first rotating shaft rotatably maintained relative to the frame body by a first bearing seat, the first rotating shaft defining first and second ends, wherein the first end of the first rotating shaft is connected with the first end of the winding roller;
• a crank handle connected to the second end of the first rotating shaft;
• and
• a second rotating shaft connected to the second end of the winding roller and rotatably maintained relative to the frame body by a second bearing seat;
• wherein the winding roller comprises three arc-shaped plates, the three arc-shaped plates are sequentially joined to form a cylindrical structure, the through groove is formed in at least one of the arc-shaped plates, and the first and second winding roller adjustment mechanisms are respectively arranged at two ends of the three arc-shaped plates.
