[0050] Working principle and use process of the utility model: After the utility model is installed, the packaging box cardboard to be polished and trimmed is placed on the placement plate 2 and the main base 1, and the polishing opening 14 on the upper polishing box 13 is aligned with the packaging box cardboard through the lifting component 2 9, and the side wall of the packaging box cardboard to be polished is extended into the polishing box 13 through the polishing opening 14;

[0051] The rotating control handle 37 drives the fixed rod 36 to rotate, and the screw rod 31 rotates through the transmission of the bevel gear set 35. Under the restriction of the limit rod 33, the lifting plate 32 drives the installation box 4 and the upper clamping wheel set 5 to move downward, and cooperates with the lower clamping wheel set 7 to clamp the packaging box cardboard;

[0052] First, the side wall of the packaging box cardboard is roughly polished by the rough polishing component 15. During this process, the operator controls the packaging box cardboard to move forward and backward. After polishing, the clamping of the packaging box cardboard is released, and the second control handle 93 is rotated to drive the threaded rod 91 to rotate, so that the threaded cylinder 92 drives the movable plate 10, the connecting plate 12 and the polishing box 13 to move in the vertical direction, so that the lower polishing box 13 is facing the packaging box cardboard, and then the packaging box cardboard is finely polished. The debris generated during the two polishing processes is confined in the polishing box 13, which can effectively prevent the packaging box debris from splashing in the working environment.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
