Description

Technical Field

[0001] The utility model relates to a carton edge folding mechanism, in particular to an efficient edge folding mechanism for carton processing, belonging to the technical field of corrugated carton production and processing. Background Technique

[0002] With the continuous development of society and the continuous update of science and technology, mechanized production has gradually penetrated into enterprises. As the most widely used packaging product, cartons are also an indispensable part of modern logistics, bearing the important responsibilities of containing, protecting products, and being aesthetically pleasing. Therefore, the carton production industry occupies an important position in China's manufacturing industry. Generally, the cartons seen in daily life are manufactured by processing corrugated paper. In addition to protecting goods, facilitating warehousing and transportation, corrugated cartons also play the role of beautifying and promoting goods. Corrugated cartons are green environmental protection products, which are conducive to environmental protection and handling and transportation. During the carton production process, edge folding treatment needs to be carried out on them.

[0003] Chinese Patent Publication No. CN220031306U discloses a carton edge folding device, which relates to the technical field of carton production. Its technical solution is: including a bottom plate, a workbench is arranged on the top of the bottom plate, connecting rods are fixedly connected to the four corners of the bottom of the workbench, and the four connecting rods are fixedly connected to the top of the bottom plate. A moving plate is arranged at the bottom of the workbench, and two L-shaped clamping blocks distributed linearly front and back are fixedly connected to the top of the moving plate. The beneficial effect of the utility model is that by controlling the motor to reverse, the threaded block, the moving plate and the two L-shaped clamping blocks can move downward, so that the inner walls of the tops of the two L-shaped clamping blocks will contact the carton, thereby pulling the carton downward to make the carton firmly adhere to the surface of the workbench, so that the positioning of the carton can be completed. Compared with air positioning, the positioning effect of this device is better, so that even when folding the edge of a hard carton, the phenomenon of carton displacement will not occur, thus ensuring the quality of edge folding.

[0004] However, the inventor believes that the above device has certain defects.
