[0021] Two rollers 10 are arranged on the left and right sides of each slider 7, and the rollers 10 can rotate around the axis. The two rollers 10 on the corresponding sides are respectively located on the front and back sides of the lower side of the cutting blade 9. The rollers 10 are subjected to a downward force, and the downward movement of the rollers 10 can place the lower side of the rollers 10 on the lower side of the cutting blade 9.

[0022] A downward electric cylinder 11 is fixed on both sides of the upper end surface of the U-shaped frame 4, and the other end of the electric cylinder 11 is fixed on the corresponding side of the upper end surface of the U-shaped rod 5. The electric cylinder 11 drives the U-shaped rod 5 to move up and down.

[0023] The cross-section of the U-shaped rod 5 is rectangular, and a rectangular through hole 12 is provided on the upper side of the left end surface of the slider 7. The slider 7 is sleeved on the U-shaped rod 5 through the rectangular through hole 12. The slider 7 can move left and right along the U-shaped rod 5. A threaded hole is provided at the front end of each slider 7, and a bolt 13 is installed in each threaded hole. After the bolt 13 is rotated backward, the rear end of the bolt 13 contacts and is fixed to the U-shaped rod 5.

[0024] A coaxial ring 14 is fixed on the inner side of the cutting blade 9, and the outer edges of the ring 14 are rotatably connected to the slider 7 via bearings on both sides, and a bump 15 is fixed on the inner edge of the ring 14. The outer edge of the rotating shaft 6 is provided with grooves 16 arranged on the left and right sides, and the bump 15 is placed in the groove 16. The rotating shaft 6 drives the cutting blade 9 to rotate via the groove 16 and the bump 15.

[0025] Two fixing blocks 17 are fixed to the lower sides of the left and right sides of the slider 7, and the two fixing blocks 17 on the corresponding sides are arranged front and back. A through hole is opened at the upper end of the fixing block 17, and a vertical rod 18 is inserted in the through hole to move along the axial direction of the through hole. A spring is sleeved on the vertical rod 18, and the upper end of the spring is fixed on the vertical rod 18, and the lower end of the spring is fixed on the fixing block 17. The spring gives a downward force to the vertical rod 18;

[0026] The rotating wheel is mounted on the lower end of the vertical rod 18.

[0027] The right end of the rotating shaft 6 passes through the U-shaped rod 5 and is placed on the right side. A motor 19 is fixed to the right end of the U-shaped rod 5. The rotating shaft 6 is installed with the motor 19 via a coupling.

[0028] It is worth mentioning that: a suction cup is mounted on the upper end surface of the operating table 1 , and the upper end of the suction cup is flush with the upper end of the operating table 1 .

[0029] Before the utility model is used, the U-shaped frame 4 is located at one end of the electric slide rail, the electric cylinder 11 is retracted upward, the motor 19 is closed, and the lower side of the roller 10 is located at the lower side of the cutting blade 9;

[0030] Before use, the bolt 13 is rotated forward, and then the slider 7 is adjusted according to the position where the carton needs to be cut. After the adjustment is completed, the bolt 13 is rotated backward to fix it;

[0031] When the utility model is used, a carton is placed on the operating table 1, and the suction cup sucks the carton to fix it; then the motor 19 is started first, the motor 19 rotates the rotating shaft 6, and the rotating shaft 6 drives the cutting blade 9 to rotate through the protrusion 15, and then the electric cylinder 11 is started, and the electric cylinder 11 is started to move the cutting blade 9 downward to the carton board to slot the carton board, and finally the electric slide 3 is started to move it along the electric slide rail, so that the cutting blade 9 completes the overall slotting operation of the carton board;

[0032] After the electric cylinder 11 is started, the electric cylinder 11 will move the slider 7 downward. Since the lower sides of the rollers 10 on the left and right sides of the slider 7 are initially located at the lower side of the cutting blade 9, the rollers 10 will first contact the carton board, and under the action of the spring, the carton board around the cutting blade 9 will further contact the upper end surface of the operating table 1. This can prevent the cutting blade 9 from cutting too deep or penetrating the groove due to the upward tilting of the carton board, making the carton board difficult to use later.

[0033] 1. The utility model first presses the carton board onto the operating table 1 through a spring via a rotating wheel, and then performs the slotting operation, which can prevent the problem of excessive slotting or penetration caused by the upward tilting of part of the carton board due to deformation.

[0034] 2. The utility model drives the cutting blade 9 to move left and right and fix it by the slider 7, which can prevent the problem of difficult operation and injury caused by the operating position being close to the cutting blade 9.
