[0025] Through the above technical scheme, when disassembling the shearing knife 707, the screw 704 is driven to rotate by rotating the fixed handle 705, so that the slider 706 moves, and the slider 706 moves back into the slide groove 702, and the fixation of the shearing knife 707 is released. The operator can disassemble the shearing knife 707 from the mounting frame 5, which is convenient for disassembly and replacement of the new shearing knife 707. The disassembly operation is simple and meets people's needs. By starting the reduction motor 302, the movable frame 305 can be moved left and right. The movement of the movable frame 305 drives the shearing knife 707 and the shearing seat 9 to move, and the shearing position can be adjusted, which is convenient for the operator to adjust the shearing position according to production needs. The structure is simple and easy to use.

[0026] Specifically, the inner wall of the movable frame 305 is fixedly connected with the connecting frame 8 , and the outer wall of the connecting frame 8 is detachably connected with the shearing seat 9 , and the inner wall of the base 2 is provided with a printing roller assembly 10 .

[0027] Through the above technical solution, the printing roller assembly 10 is a prior art and will not be described in detail here. A controller is provided on the support seat 1.

[0028] Specifically, the reduction motor 302 and the moving frame 305 form a moving structure through the screw rod 303 , and one end of the screw rod 303 is threadedly penetrated through the thread groove 306 .

[0029] Through the above technical solution, the connection effect between the reduction motor 302, the screw rod 303 and the movable frame 305 is strengthened. By starting the reduction motor 302, the screw rod 303 can be rotated. The screw rod 303 rotates more stably relying on the fixed bearing 304, and the threads in the thread groove 306 match the threads on the screw rod 303.

[0030] Specifically, the shape and size of the inner wall of the long slot 301 match the shape and size of the outer wall of the movable frame 305 , and the inner wall of the long slot 301 fits the outer wall of the movable frame 305 .

When the movable frame 305 moves, it moves more stably in the long groove 301. The movable frame 305 is provided with a groove. When the movable frame 305 moves, it moves more stably on the long rod 307 by relying on the groove.

[0032] Specifically, the mounting frame 5 forms a sliding structure with the shearing knife 707 through the mounting groove 701 , and the outer wall of the shearing knife 707 fits with the inner wall of the mounting groove 701 .

[0033] Through the above technical solution, the connection effect between the mounting frame 5 and the mounting groove 701 and the shearing knife 707 is strengthened, so that the shearing knife 707 can be well extended into the mounting groove 701 for installation.

[0034] Specifically, the mounting frame 5 forms a threaded structure through the nut 703 and the screw rod 704, and one end of the screw rod 704 extends into the nut 703 for connection.

[0035] Through the above technical solution, the connection effect between the mounting frame 5 and the nut 703 and the screw rod 704 is enhanced, and the threads in the nut 703 match the threads on the screw rod 704, so that the screw rod 704 can rotate well in the nut 703.

[0036] Specifically, the shape and size of the slider 706 match the shape and size of the limiting groove 708, and one end of the slider 706 extends into the limiting groove 708 for connection.

[0037] Through the above technical solution, the connection effect between the slider 706 and the limiting groove 708 is strengthened, so that the slider 706 can be well moved and extended into the limiting groove 708.

[0038] When the shearing knife 707 becomes blunt after long-term use and needs to be replaced with a new one, the operator can rotate the fixed handle 705, and the fixed handle 705 drives the screw rod 704 to rotate in the nut 703, so that the slider 706 moves, and the slider 706 moves out of the limiting groove 708 and moves back into the sliding groove 702, thereby releasing the limit on the shearing knife 707. The operator can then remove the shearing knife 707 from the mounting groove 701 of the mounting frame 5, and the operator inserts the new shearing knife 707 into the mounting groove 701 of the mounting frame 5, and rotates the fixed handle 705 to move the slider 706, and one end of the slider 706 moves from the sliding groove 702 to extend into the limiting groove 708, thereby releasing the limit on the shearing knife 707. The clamping and fixing, installation and disassembly operations are simple, which meets people's needs. When the shearing position of the shearing knife 707 needs to be adjusted, the reduction motor 302 is started to rotate the screw rod 303, thereby moving the movable frame 305, and the movement of the movable frame 305 drives the cylinder 4 to move, and the movement of the cylinder 4 drives the shearing knife 707 and the shearing seat 9 to move, so that the shearing position can be adjusted, which is convenient for the operator to adjust the shearing position according to production needs. The structure is simple and easy to use. When cutting, the cylinder 4 works to drive the shearing knife 707 to move down to cut the printed matter, which completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
