It has the characteristics of lightness, firmness, environmental protection, low cost, etc., and is widely used in logistics, retail, food, electronics and other industries. The carton can be designed into different shapes and sizes according to the needs, and can be quickly formed through folding, sealing (such as adhesive tape or hot melt adhesive), etc., and the surface can be printed with patterns or words, combining functionality and aesthetics.

[0003] Carton packaging is a packaging method that places goods into a carton, fills it reasonably, folds it and seals it with adhesive tape to ensure the safety and stability of the goods during transportation and storage. In the automatic equipment processing process, the carton filled with goods is placed on the conveying roller, and the conveying roller can only realize the movement of the carton on the equipment. In the prior art, the work personnel sets conveying belts on both sides of the conveying roller, and when it is necessary to drive the carton to move forward on the conveying roller, the cylinder drives the conveying belts on both sides to move close to the carton. When the conveying belts abut against the carton, with the movement of the conveying belts, the carton is conveyed on the carton sealing machine.

[0004] According to the related technology in the above, the inventors believe that the conveying belts abut against the carton under the action of the cylinder, and with the continuous passing of the carton between the two conveying belts, the two conveying belts will move away from each other under the action of the carton, thereby affecting the conveying of the subsequent carton.
