Description

Technical Field

[0001] The utility model relates to the technical field of folding mechanisms, in particular to a folding mechanism for carton processing. Background Art

[0002] As an important container widely used in commodity packaging and logistics transportation, carton has become particularly important for efficient and automated processing and production as its demand continues to grow. In traditional carton processing, the folding process usually relies on manual operation or traditional mechanical folding mechanism, both of which have certain limitations and low efficiency. Manual operation easily leads to poor consistency and unstable quality. With the development trend of automated production and intelligent manufacturing, the demand for increasing efficiency, ensuring product quality consistency and reducing labor costs has become more urgent. Therefore, it is particularly important to design a folding mechanism for carton processing.

[0003] Utility model publication number CN217495359U discloses a folding mechanism for carton processing, comprising a base, a support plate, and a die. A slot is horizontally defined on one side of the base, one end of which communicates with the interior of the base. An adjusting screw is inserted into the slot, and the threads on both sides of the adjusting screw have opposite patterns.

[0004] The above technical solution, through the coordinated use of the positioning groove, the positioning block, the upper limit groove, the lower limit groove and the I-shaped limit block, inserts the positioning block on the die into the positioning groove on the lower surface of the support plate, which can perform preliminary positioning and installation of the die to prevent the die from moving left and right. After the positioning block is inserted into the positioning groove, the lower limit groove on the die and the upper limit groove on the lower surface of the support plate are connected to form an I-shaped distribution, and then the I-shaped I-shaped limit block is inserted to limit and fix the die to the support plate. The structure is simple, the installation and disassembly of the die is convenient, and different dies can be replaced according to needs, which is suitable for wide promotion and use; however, in actual use, when the device processes cartons of different sizes, dies of different sizes need to be replaced, the operation is complicated, and the production cost is high. At the same time, after the carton is die-casted, the carton cannot be folded and needs to be folded manually. In addition, the machine has a large space occupancy rate and is not convenient for transportation and transfer. Utility Model Content
