[0035] Please refer to Figures 6 to 8 The moving mechanism 8 includes a vertical groove 801, which is opened on one side of the inner wall of the mounting frame 701, and a horizontal groove 802 is opened on the top of one side of the inner wall of the vertical groove 801. The inner wall of the vertical groove 801 is slidably connected with a slide plate 803, and the outer wall of the slide plate 803 is fixedly connected with a tooth plate 804. The interior of the mounting frame 701 is located at one side of the outer wall of the tooth plate 804 and is rotatably connected with a first straight gear 805. The top end of the mounting seat 3 is located at one end of the groove 710 and is rotatably connected with a rotating plate 806. The first straight gear 805 is fixedly connected to the rotating plate 806. The moving mechanism 8 also includes a rotating block 807, which is arranged at one end of the slide plate 803, and the outer wall of the rotating block 807 is fixedly connected with a fixed shaft 808, and the fixed shaft 808 is rotatably connected to the slide plate 803. A torsion spring 809 is connected to the outer wall of the fixed shaft 808 between the rotating block 807 and the skateboard 803, and a first bevel gear 810 is fixedly connected to the outer wall of the fixed shaft 808. The interior of the skateboard 803 is located at the outer wall of the first bevel gear 810 and is rotatably connected to the second bevel gear 811, one end of the second bevel gear 811 is fixedly connected to a connecting shaft 812, and one end of the connecting shaft 812 is fixedly connected to a third bevel gear 813. The interior of the skateboard 803 is located at the outer wall of the third bevel gear 813 and is rotatably connected to a fourth bevel gear 814, one end of the fourth bevel gear 814 is fixedly connected to a first threaded rod 815, and the interior of the skateboard 803 is slidably connected to a slider 816 extending to the outer wall of the skateboard 803, and the first threaded rod 815 extends to the interior of the slider 816.

[0036] In this embodiment: when the cutter 704 and the movable seat 703 move downward to cut the paper, the slide plate 803 is located at the bottom end of the vertical groove 801, and the slider 816 contacts the inner wall of the vertical groove 801, so that the slider 816 cannot move out of the slide plate 803; when the movable seat 703 moves downward, the movable seat 703 contacts the rotating block 807 and drives the rotating block 807 to rotate downward, the rotating block 807 rotates to drive the fixed shaft 808 to rotate, the fixed shaft 808 rotates to drive the first bevel gear 810 to rotate, the first bevel gear 810 rotates to drive the second bevel gear 811 to rotate, the second bevel gear 811 rotates to drive the connecting shaft 812 to rotate, the connecting shaft 812 rotates to drive the third bevel gear 813 to rotate, the third bevel gear 813 rotates to drive the fourth bevel gear 814 to rotate, the fourth bevel gear 814 rotates to drive the first threaded rod 815 to rotate, and the first threaded rod 815 rotates to drive the slider 816 to move. At this time, the sliding block 816 can only slide into the sliding plate 803 because it is blocked by the side wall of the vertical groove 801, so that the rotating block 807 can only rotate downward.

[0037] After the rotating block 807 is separated from the movable seat 703, the rotating block 807 is reset by the torsion force of the torsion spring 809; when the cutting is completed and the movable seat 703 moves upward, the movable seat 703 contacts the lower bottom surface of the rotating block 807, and the rotating block 807 cannot rotate. The movable seat 703 pushes the slide plate 803 to move upward in the vertical groove 801 through the rotating block 807, and the displacement of the slide plate 803 drives the tooth plate 804 to move, and the displacement of the tooth plate 804 drives the first spur gear 805 to rotate, and the rotation of the first spur gear 805 drives the rotating plate 806 to rotate, and the rotating plate 806 rotates in an inclined state, and the cutting is completed. The formed paper slides onto the first conveyor belt 4 through the inclined surface of the rotating plate 806 until the slider 816 contacts the transverse groove 802, so that the slider 816 can enter the transverse groove 802 and slide out of the slide plate 803, so that the rotating block 807 can rotate upward; at this time, the movable seat 703 that continues to move upward drives the rotating block 807 to rotate upward until the rotating block 807 is separated from the movable seat 703, and the rotating block 807 is reset by the torsion of the torsion spring 809, and the slider 816 moves out of the transverse groove 802. At this time, the rotating plate 806 is reset by gravity, thereby driving the slide plate 803 to move to the bottom of the vertical groove 801. This design facilitates the automatic movement of the cut paper to the first conveyor belt 4 for transportation after cutting, and prevents the paper from accumulating and remaining on the mounting seat 3, which affects the subsequent cutting operation.

[0038] Please refer to Fig. 9The mounting mechanism 9 includes a socket 901, which is provided on the outer wall of the cutter 704.

[0039] In this embodiment: when the cutter 704 is replaced, the rotating column 907 can be rotated, and the rotation of the rotating column 907 drives the second threaded rod 906 to rotate, and the rotation of the second threaded rod 906 drives the displacement plate 904 to slide in the displacement groove 905. The displacement of the displacement plate 904 drives the plug block 903 to move out of the socket 901, canceling the fixation of the cutter 704, so that the cutter 704 can be removed for replacement, and then the new cutter 704 is connected to the installation groove 902, and then the rotating column 907 is rotated to drive the plug block 903 to be inserted into the socket 901, and the cutter 704 is fixed. This design facilitates the rapid replacement of the cutter 704.
