[0025] Working principle:

[0026] Preparation process:

[0027] The operator first places the corrugated paper box that needs to be creasing for the second time on the surface of the conveying roller 2.

[0028] Adjustment process:

[0029] Start the power supply of the first servo motor 402, the output shaft of the first servo motor 402 rotates to drive the worm 403 to rotate, thereby driving the worm wheel 404 to rotate, the rotation of the worm wheel 404 drives the rotating rod 405 to rotate, thereby driving the cylinder 406 to slide along the slide groove processed on the slide bar 407, and then drives the slide bar 407 to move, the movement of the slide bar 407 drives the second shell 501 to move, and at the same time drives the block 8 to slide along the slide groove processed on the bent plate 3, the movement of the second shell 501 drives the moving plate 6 and the positioning wheel 7 to move, when the positioning wheel 7 moves to the position directly above the position where the corrugated paper box needs to be secondary indented, turn off the power supply of the first servo motor 402, the positioning wheel 7 can be adjusted left and right, and the secondary indentation work can be performed on different positions of the corrugated paper box, thereby reducing the working limitations.

[0030] Positioning process;

[0031] The operator starts the second servo motor 502, and the output shaft of the second servo motor 502 rotates forward to drive the threaded rod 503 to rotate, thereby driving the slider 504 to slide along the slide groove processed on the second shell 501, and the movement of the slider 504 drives the first connecting rod 507 to drive the second connecting rod 506 to move, and at the same time drives the two slides 508 to move along the inner wall of the frame 509, thereby driving the vertical rod 510 to move downward, and the downward movement of the vertical rod 510 drives the movable plate 6 and the positioning wheel 7 to move downward. When the positioning wheel 7 moves downward to the depth of the indentation of the corrugated paper box, the second servo motor 502 is turned off. When the second servo motor 502 needs to be moved upward, the operator reverses the output shaft of the second servo motor 502 to drive the positioning wheel 7 to move upward.

[0032] Secondary creasing process of corrugated box:

[0033] After adjusting the position of the primary indentation, start the external power source of the conveying roller 2 to drive the conveying roller 2 to move, and place the corrugated paper box that needs to be indented for the second time on the surface of the conveying roller 2. The conveying roller 2 drives the corrugated paper box to move backward. Through the cooperation of the conveying roller 2 and the positioning wheel 7, the corrugated paper box is indented once. The conveying roller 2 drives the corrugated paper box after the primary indentation to move backward. When it is completely moved out, the operator reverses the output shaft of the second servo motor 502 to reset the positioning wheel 7, and then operates to start the power supply of the first servo motor 402 to control the positioning wheel 7 to move to the position of the secondary indentation of the corrugated paper box, and then starts the power supply of the second servo motor 502 again to drive the positioning wheel 7 to move downward. When the positioning wheel 7 moves downward to the depth of the secondary indentation, the operator controls the conveying roller 2 to make the conveying roller 2 drive the corrugated paper box to move forward. Through the cooperation of the conveying roller 2 and the positioning wheel 7, the corrugated paper box is indented for the second time. The operator collects the corrugated paper box after the secondary indentation at the front end of the conveying roller 2.
