The setting that one end of the guiding bar 5 is guiding can better convey and guide the cardboard box to be hemmed, so that the hemming operation can be better carried out. At the same time, the stability between the two sets of supporting legs 21 on the same side can be strengthened through the setting of the guiding bar 5.

[0022] In this embodiment, when an operator needs to perform a hemming operation on a cardboard box, the cardboard box is placed on the conveyor 1 for conveying. The operation of the conveyor 1 drives the cardboard box to move along. During the conveying process, the cardboard box first passes through the guiding end of the guiding bar 5 for guiding, so that the cardboard box follows the conveyor 1 and moves to the lower part of the hemming auxiliary bottom plate 4. At this time, the conveyor 1 pauses operation. Then, the first motor 23 is powered on for operation. The first motor 23 drives the mounting frame 27 to move up and down through the screw rod 24. When the mounting frame 27 moves up and down, it drives the adjusting outer ring 26 to slide up and down along the supporting leg 21 for adjustment. When the adjusting outer ring 26 moves, it drives the hemming assembly 3 to move along. After the height position of the hemming rod 34 is adjusted through the adjusting outer ring 26, the operator powers on the second motor 31 for operation. The operation of the second motor 31 drives the two hemming rods 34 to perform width adjustment operation through the bidirectional threaded rod 32 and the connecting block 33, so that the width of the two hemming rods 34 meets the requirements of the cardboard box width specification. Then, the adjusting outer ring 26 moves downward, so that the adjusting outer ring 26 drives the hemming rod 34 to perform a hemming operation on the cardboard box. At the same time, the conveyor 1 continues to operate, so as to complete the continuous conveying operation of the cardboard box after hemming, and further complete the hemming operation on the cardboard box.

[0023] The above specific embodiment is only a preferred embodiment of the present invention.
