[0002] With the rapid development of the Internet era, logistics and express delivery after online shopping has become an indispensable part of people's daily life. In the process of express delivery of goods, it is necessary to use packaging boxes to package online shopping goods, so as to effectively protect online shopping goods. Packing boxes are mainly for the convenience of transportation, loading and unloading and warehousing. They are generally made of corrugated paper. They are light in material and heavy in load-bearing. They can be customized according to the size and specifications of the goods. They are mainly used to replace wooden boxes for transportation. They are fast to assemble, save time and labor, have exquisite craftsmanship, good sealing performance, and can save a lot of wood resources. They are internationally recognized and promoted new environmentally friendly packaging products. They can be used in the packaging industry, stone industry, home appliance industry, furniture industry, electronic communications, electromechanical machinery, clothing and other industries. It is the development trend of international packaging material applications in the future. In the production process of packaging boxes, a box folding machine is needed to fold the corrugated cardboard to form a packaging box.

[0003] The existing patent (announcement number: CN216400706U) discloses a carton folding machine, which includes: a frame, a first conveying device, a second conveying device and a folding device. The first conveying device is installed on the frame through a bracket; the second conveying device is arranged above the first conveying device, and the carton can pass between the first conveying device and the second conveying device; the folding device is arranged on the frame and is located on one side of the second conveying device, and the folding device includes a first conveyor belt. The first conveying device and the second conveying device convey the carton board to the folding device, and the first conveyor belt fits the folds on both sides of the carton board and folds the carton board completely. The first conveying device, the second conveying device and the folding device have a compact structure, and the coordination and connection are smooth and fast. The carton board can be folded quickly, which can improve the production efficiency of the carton. At the same time, it can also ensure that the structure of the folded carton is symmetrical and the appearance is beautiful, thereby improving the product quality of the carton.

[0004] The above-mentioned comparative document points out that the size of the folding device of the corrugated box folding machine is fixed, and it can only fold cartons of one specification during use. When cartons of multiple specifications need to be folded, it is necessary to replace folding machines of different specifications for folding, and the scope of application is relatively low.

[0013] Through the above solution, by setting the linear module and the third motor, the suction cup can absorb corrugated boxes of different heights, and by setting the third push rod, the suction cup can absorb forwards.

[0014] Furthermore, a plurality of groups of pulley fixing plates distributed in a linear array are fixedly connected to the upper end of the base plate, wherein each group is composed of two pulley fixing plates distributed in a mirror image, and bearings are fixedly connected to the inner upper ends of the two pulley fixing plates, and the inner rings of the two bearings are fixedly connected to the same rotating shaft, and the surface of the rotating shaft is fixedly connected to a pulley.

[0015] According to the above scheme, the pulley can be provided to facilitate the folding of the corrugated box when it is moved.

[0016] Furthermore, two first electric push rod fixing plates are fixedly connected to the upper end of the base plate, one side corresponding to the two first electric push rod fixing plates is fixedly connected to the first electric push rod, and the output ends of the two first electric push rods are fixedly connected to the first push plates.
