[0002] A carton folding system typically consists of multiple components, including an automatic loading device, a folding die, a conveying system, and a control system. The folding die is the core component of the entire system and is typically customized to suit the size and shape of the carton. The conveying system can also be adjusted to meet production needs, enabling high-speed, continuous production. High-efficiency carton folding systems can significantly improve the efficiency and quality of carton processing lines. Their ease of operation, high precision, and excellent stability make them suitable for the production of various cartons.

[0003] In the prior art, Chinese patent document CN220280667U provides a high-efficiency carton folding device for carton processing. Its technical solution includes: a base and a press strip. The base has a placement slot in the middle of the upper surface, and a movable plate is movably installed in the placement slot. A top plate is fixedly installed above the base, and a second electric telescopic rod is fixedly installed in the middle of the lower surface of the top plate. The lower surface of the top plate has a slide fixedly installed in a rectangular array, and the slide has a first electric telescopic rod movably installed on it. This utility model solves the problem of low crease pressing efficiency in the prior art.

[0004] Although the above device can enhance the efficiency of crease pressing to a certain extent, in actual use, the above device has a poor folding effect on the bottom of the carton, and it is easy to affect the folding efficiency of the carton to a certain extent when used. In view of this, we propose an efficient carton folding device for carton processing. Utility Model Content

[0018] 2. In the present invention, the box-taking mechanism is used to suck the carton blanks placed in the placement box into the working area. The box-taking mechanism works in conjunction with the reset plate. In the process of the carton blanks moving to the working area of ​​the folding mechanism, the folded part of the carton that originally exceeded the working area will be gradually reset by the limiting influence of the reset plate, and the folded carton blanks will also gradually expand to form the shape of the box body. The box-taking mechanism picks up the carton through the suction cup of the vacuum pump, which can reduce the destructive force of conventional clamps on the carton, thereby achieving proper protection of the carton and further enhancing the quality of the finished carton.
