[0029] The interception plate 13 is a curved structure, one side of the interception plate 13 is on the same horizontal line as the disc blade 11, and the interception plate 13 is located on the side of the disc blade 11 close to the electric paper winding roller 2;

[0030] Specifically, Figure 1 , Figure 4 As shown, when in use, the special structure of the interception plate 13 is used to intercept and guide the paper waste, so that the accumulated paper waste is turned over and wound around the winding rod 14, and then the paper waste is individually wound;

[0031] A mounting plate 10 is installed on one side of the bottom end of the horizontal plate 5, and a rotating shaft 15 is installed on one side of the mounting plate 10. An isolation ring 16 is sleeved on the outside of the rotating shaft 15, and a disc blade 11 is installed on the side of the isolation ring 16 away from the mounting plate 10;

[0032] The bottom end of the disc blade 11 abuts against the top end of the cutting table 1. After the paper passes through the bottom end of the disc blade 11, it needs to go around the top end of the guide rod 3 and connect to the outside of the electric paper winding roller 2.

[0033] Specifically, Figure 1 As shown, when in use, the guide rod 3 is used to guide the printed paper to ensure that the printed paper is fully in contact with the bottom end of the disc blade 11 during the cutting process, so that the disc blade 11 rotates and cuts the printed paper;

[0034] Both sides of the disc blade 11 are provided with assembly mechanisms;
