In order to make the objects and advantages of the present invention more clear, the present invention will be described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention, and does not strictly limit the protection scope of the specific claims of the present invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include reasonable and inconsistency tolerances for machining or human error; the specifics of the cardboard stacking device are detailed below. feature:

The raw cardboard of the packaging box is neatly stacked in the cardboard exporting device, and the cardboard raw material can be exported to the cardboard cutting device individually and intermittently through the cardboard exporting device. The specific structure of the cardboard exporting device is a common cardboard separator in the market. , which can export the cardboard raw materials intermittently and individually to each equipment in the subsequent production line;

The above-mentioned cardboard incision device implements the opening operation on the raw cardboard, and an opening for easy crease is opened at one end of the raw cardboard to facilitate subsequent crease operations, and a position that can facilitate the bottom sealing of the packaging box is reserved to ensure the packaging box. The reliability of the back cover; the cardboard incision device exports the cardboard to the crease device for crease operation, thereby forming all the creases of the packaging box, and the raw cardboard of the packaging box after the crease is exported to the cardboard stacking device 40, so that The raw cardboard is folded along the folds into a pressed cardboard for export, so as to avoid the problem of incomplete folds and rebound. To ensure the integrity of the packaging box, the folded cardboard opens a threading hole at the position of the folded fold of the cardboard through the opening device, that is, the above-mentioned opening, and then uses the threading device to thread the strapping in the threading hole. , The strapping belt can be a special polymer flexible cord, which can effectively achieve the binding effect on the packaging box;

With reference to Figures 3 to 13, the following describes in detail how the folded cardboard is folded:

Specifically, the cardboard stacking device 40 includes a rope disposed at the exit of the crease device 30 , the rope includes an upper climbing rope 41 and a lower climbing rope 42 , and the upper climbing rope 41 and the lower climbing rope 42 are mutually Approaching or moving away, a passage for the cardboard to pass through is provided between the upper climbing rope 41 and the lower climbing rope 42, and a clamping mechanism is provided on both sides of the passage for the cardboard to pass through, and the clamping mechanism is used to connect the two sides of the cardboard. Clamping, the clamping mechanism is connected with the pushing and folding mechanism, and the pushing and folding mechanism moves toward each other along the width direction of the passage through which the cardboard passes;

3 and 9, when the cardboard folding operation is completed, the cardboard is guided to the position of the cardboard stacking device 40, and the clamping mechanisms on both sides of the cardboard passage are activated to implement the clamping operation on both sides of the cardboard. , and then the upper climbing rope 41 and the lower climbing rope 42 are approached up and down, so as to realize the tightening operation on the crease. During the climbing operation of the upper climbing rope 41 and the lower climbing rope 42, the push-and-fold mechanism is activated, so as to realize the folding of the cardboard. Further folding operation at the crease ensures that the cardboard can be further clamped and clamped at the crease to avoid the problem of rebound of the cardboard;

The upper climbing rope 41 is provided with multiple groups, and the length direction of the upper climbing rope 41 is consistent with the traveling direction of the cardboard, that is, the width direction of the cardboard, and the upper climbing rope 41 can abut against the crease a and the crease b, thereby It is clamped in the crease a and crease b of the upper board surface of the cardboard. The lower climbing ropes 42 are arranged in multiple groups, and the length direction is parallel to the upper climbing ropes 41. The position of the lower climbing ropes 42 leads to the crease c. Corresponding to the position of the crease d, during the ascending process of the lower climbing rope 42, the lower climbing rope 42 can be clamped in the crease c and the crease d, so as to form a clear outline, which is convenient for the subsequent pushing and folding mechanism to carry out the adjustment. In the folding operation of the cardboard, the folding position can be ensured at the above four fold positions, so that the folds are clearer, and then in the process of folding the cardboard, it can be ensured that the cardboard is folded at the folds. further stabilization to prevent the cardboard from bouncing off the crease.
