[0074] The box conveying structure 520 is fixedly arranged on the boxing machine rack 001. The box conveying structure 520 includes a second box conveying end and a first box conveying end. The first box conveying end is arranged below the packaging box placing device 510, and the second box conveying end is connected with the second boxing conveying line 310 and the first boxing conveying line 210. The box conveying structure 520 can selectively convey the packaging boxes to the second boxing conveying line 310 or the first boxing conveying line 210, so as to realize the diversion of the packaging boxes. The box conveying structure 520 is used to convey the packaging boxes from the first box conveying end to the second box conveying end.

[0075] Specifically, in the embodiment, the box feeding conveying structure 520 comprises a box feeding main conveying line 521 and a box feeding lifting conveying device 522. The two sides of the box feeding main conveying line 521 and the box feeding lifting conveying device 522 are provided with baffle plates 611 for limiting the packaging boxes.

[0076] The box feeding main conveying line 521 is a conventional belt conveyor. In the embodiment, the conveying direction of the box feeding main conveying line 521 is opposite to the material conveying direction, and the first box feeding end is the starting end of the box feeding main conveying line 521.

[0077] Specifically, in the embodiment, the box feeding main conveying line 521 comprises two box feeding belts which are parallel and horizontally arranged. The box feeding belts are conventional belt conveyors, and the two box feeding belts move synchronously.

[0078] The box feeding lifting conveying device 522 comprises a belt conveyor and a lifting driving structure. The lifting driving structure drives the belt conveyor to move up and down, and the belt conveyor drives the packaging boxes to move in the same direction as the material conveying direction or in the opposite direction to the material conveying direction, so that the packaging boxes enter the first box loading conveying line 210 or the second box loading conveying line 310, thereby realizing the diversion of the packaging boxes and meeting the requirement of multi-station material loading.

[0081] When it is necessary to take the packaging boxes, the suction disc driving member 532 drives the suction disc structure 531 to approach the packaging box taking-out position. The suction disc structure 531 adsorbs the lowermost packaging box at the packaging box taking-out position. Then, the suction disc driving member 532 drives the suction disc structure 531 to move away from the packaging box taking-out position. When the height of the suction disc structure 531 is lower than the conveying plane of the box feeding belt, the packaging box is blocked by the box feeding belt and cannot continue to be transported downward, so that the suction disc structure 531 is separated from the packaging box, and then the box feeding belt can transport the packaging box.

[0082] The implementation process of the scheme is that the box taking device 530 first takes the packaging box from the packaging box placing device 510, and then the box conveying line 521 transports the packaging box to the box conveying and lifting device 522. After the packaging box moves to the box conveying and lifting device 522, the box conveying and lifting device 522 drives the packaging box to ascend, and then the box conveying and lifting device 522 drives the packaging box into the first box loading assembly 200 or the second box loading assembly 300.

[0083] The packaging box in the first box loading assembly 200 is transported by the first box loading conveying line 210 to move away from the box conveying line 400. During the transportation of the packaging box by the first box loading conveying line 210, the materials are carried into the packaging box by other components, so as to realize the loading of the materials. When the packaging box is transported to the first lifting conveying device 220, the first lifting conveying device 220 drives the packaging box to move upward. When the packaging box moves to the first high-position output 222, the first lifting conveying device 220 drives the packaging box into the box returning conveying line 230. The box returning conveying line 230 drives the packaging box to move close to the box conveying line 400. Finally, the box returning conveying line 230 transports the packaging box to the second lifting conveying device 240. Then, the packaging box is transported by the second lifting conveying device 240 to move from the second high-position input 242 to the second low-position output 241. When the packaging box is conveyed to the second low-position output 241, the second lifting conveying device 240 conveys the packaging box to the box conveying line 400.

[0084] The packaging box in the second box loading assembly 300 is transported by the second box loading conveying line 310 to move close to the box conveying line 400. During the transportation of the packaging box by the second box loading conveying line 310, the materials are carried into the packaging box by other components, so as to realize the loading of the materials. When the packaging box is transported to the third lifting conveying device 320, the third lifting conveying device 320 drives the packaging box to move upward. When the packaging box moves to the third high-position output 322, the third lifting conveying device 320 conveys the packaging box to the box conveying line 400.

[0085] By arranging the first box loading assembly 200 and the second box loading assembly 300, the working efficiency of the box loading machine can be improved.

[0086] By arranging the box returning conveying line 230, the first lifting conveying device 220, the second lifting conveying device 240, and other components, the box conveying line 400 and the material conveying line 110 can be arranged at the same end, so that the overall structure of the box loading machine is more compact, and the use of the previous arrangement of the box conveying line 400 and the material conveying line 110 at both ends of the box loading machine can be avoided, so that the factory space occupied by the box loading machine is reduced.

[0087] The preferred embodiments of the present application are specifically described above, but the present application is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. The equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
