The cutting assembly includes a support frame 2, a lifter 3, a sliding frame 4, a first motor 5, a left-right threaded screw 6, a slider 7 and a cutting knife 8. The support frame 2 is in a U shape. The turntable 14 is embedded on the workbench 1. Two free ends of the support frame 2 are arranged on both sides of the turntable 14. The lifter 3 penetrates through the top wall of the support frame 2 and is connected to the sliding frame 4. The left-right threaded screw 6 and the slider 7 are arranged in the sliding frame 4. The output end of the first motor 5 penetrates through the sliding frame 4 and is connected to the left-right threaded screw 6. The left-right threaded screw 6 is threadedly connected to two symmetrically arranged sliders 7. A cutting knife 8 is further arranged below the slider 7. A clamping assembly for fixing the material is also arranged on the workbench 1.

[0021] A turntable 14 is arranged on the workbench 1, which facilitates the rotation and adjustment of the position of the material. When placing the material, the lifter 3 drives the sliding frame 4 to descend. The first motor 5 drives the left-right threaded screw 6 in the sliding frame 4 to rotate. The two sliders 7 drive the cutting knife 8 to move towards each other, which is convenient for centering and auxiliary limiting of the material. Then the lifter 3 resets. The first motor 5 drives the left-right threaded screw 6 to rotate, adjusts the position of the cutting knife 8 again. The lifter 3 drives the sliding frame 4 to descend, and the cutting knife 8 trims the material. It should be noted that the height of the output end of the clamping assembly and the turntable 14 is less than the stroke of the cutting knife 8, and there will be no movement interference.
