The threaded rod 11 is fixed to the top of the concave block 9 and extends to its outside and is fixedly connected to the rotating block 12. The surface of the rod 11 is threadedly connected to an adjusting block 13, and the bottom of the adjusting block 13 contacts the top of the fixed block 10. The left and right sides of the bottom of the adjusting block 13 are fixedly connected with connecting blocks 14. The bottom of the connecting block 14 passes through the fixed block 10 and extends to the outside thereof. The bottoms of the two connecting blocks 14 are fixedly connected by an adjusting plate 15, and the bottom of the adjusting plate 15 is fixedly connected to a limiting block 16. A limiting groove 17 adapted to the limiting block 16 is provided at the top of the mounting seat 6 and at the position corresponding to the limiting block 16. The limiting block 16 passes through the movable plate 3 and the limiting groove 17 from top to bottom and extends to the inside of the limiting groove 17 and contacts the inner wall of the limiting groove 17.

[0028] Specifically, rotate the rotating block 12, the rotating block 12 drives the threaded rod 11 to rotate, the threaded rod 11 drives the adjusting block 13 to move upward, the adjusting block 13 drives the adjusting plate 15 to move upward through the connecting block 14, so that the adjusting plate 15 drives the limiting block 16 to move upward, so that the limiting block 16 and the limiting slot 17 are separated, and then the mounting seat 6 is pulled backward, the mounting seat 6 drives the cutting knife 4 to move backward, the mounting seat 6 drives the slot 7 to move backward and separate from the insert block 8, and the cutting knife 4 can be disassembled for maintenance and repair.

[0029] Through the mutual cooperation of the movable plate 3, the limit frame 5, the mounting seat 6, the slot 7, the insert block 8, the recessed block 9, the fixed block 10, the threaded rod 11, the rotating block 12, the adjusting block 13, the connecting block 14, the adjusting plate 15, the limit block 16 and the limit slot 17, the cutting knife 4 can be conveniently disassembled for maintenance and overhaul, making the disassembly and assembly process simple and convenient, thereby improving practicality.

[0031] Through the mutual cooperation of the limit frame 5, the stabilizing block 18, the fixing rod 19, the movable block 20, the buffer spring 21 and the moving block 22, the cutting position of the lettering film can be limited and fixed, thereby avoiding the deviation of the lettering film during cutting, thereby avoiding affecting the cutting quality.

[0032] During use, the lettering film moves from front to back through the two guide rollers 24 to the top of the base 1, and then the electric push rod 23 is started. The electric push rod 23 drives the movable plate 3 to move downward, and the movable plate 3 drives the limit frame 5 and the cutting knife 4 to move downward, so that the limit frame 5 comes into contact with the lettering film first. At this time, the movable plate 3 is still driving the cutting knife 4 to move downward, so that the stable block 18 and the movable block 20 are close to each other to squeeze the buffer spring 21 to move. The elastic force of the buffer spring 21 ensures that the limit frame 5 has the effect of limiting and fixing the lettering film, so that the cutting knife 4 passes through the limit frame 5 to cut the lettering film.
