When the box cover bending assembly bends the left box cover 75, the operation process is the same as the above process, except that the second driving member 63 drives the second bending member 66 to move in the direction opposite to the second direction.

In this embodiment, the first bending assembly and the second bending assembly are provided with two sets, namely, the first bending assembly is provided with a right-side bending assembly 6 and a left-side bending assembly 7, and the second bending assembly is provided with a right-side bending assembly and a left-side bending assembly, so as to respectively bend the left box cover 75 and the right box cover 76. That is, as shown in fig. 1, 10 and 14, it is preferable that the cover bending assemblies have two sets, and the two sets perform bending operations on the left cover 75 and the right cover 76, respectively. In addition, the first bending member may be a set which sequentially performs the bending operation of the left case lid 75 and the right case lid 76 by being movable on the second support member, and similarly, the second bending member may be a set which sequentially performs the bending operation of the left case lid 75 and the right case lid 76 by being movable on the first support member.

After the above bending operation of the left box cover 75 and the right box cover 76 is completed, the left box cover 75 and the right box cover 76 need to be folded to seal the box opening, and since the bent left box cover 75 or the bent right box cover 76 surrounds the rotating block 50, the rotating block 50 can be directly driven by the rotating driving member 52 to rotate, and then the left box cover 75 and/or the right box cover 76 are driven to rotate, so that the left box cover 75 and/or the right box cover 76 at the outward-turning position are close to the box opening position, and thus the aforementioned box cover which is driven by the rotation driving assembly 5 to be bent per se needs to be rotated to realize folding more conveniently. In this embodiment, the rotation block 50 preferably rotates the left cover 75 and/or the right cover 76 by 130 degrees from the everted position to a direction close to the opening of the carton under the detection of the sensor and the control of the controller of the carton folding device, as shown in fig. 16 and 17, so that the left cover 75 and/or the right cover 76 is close to the opening but not in the opening position, that is, the left cover 75 and/or the right cover 76 stays at the rotation stop position, and then the left and right driving assemblies drive the left cover 75 and/or the right cover 76 to move to the opening position.

In this embodiment, as shown in fig. 8, it is preferable that the rotation assembly (the rotation assembly is different from the rotation driving assembly by the mounting plate 45 without the lifting mechanism and the mounting plate for mounting the rotation driving member 52) composed of the rotation block 50, the rotation driving member 52 and the sensor has two sets to respectively drive the left case cover 75 and the right case cover 76 to rotate, or only one set of rotation assembly may be provided to sequentially realize the auxiliary bending and rotation driving of the left case cover 75 and the right case cover 76 by being able to move on the mounting plate 45.
