Description

Technical Field

[0001] The utility model relates to the field of carton processing equipment, in particular to a carton quick bottom-hooking device. Background Technique

[0002] In the packaging and printing industry, the application of carton gluing machines is the last process of carton processing, which folds and glues the printed and die-cut carton boards into shape. With the progress of technology, manual labor has gradually been replaced by mechanical processing. The carton gluing machines used for carton processing production have a complete carton production combination folding mechanism, which can directly and automatically fold and combine a whole cardboard into a complete box body. Machine carton gluing replaces the manual carton gluing method, reducing labor costs and improving efficiency.

[0003] Carton gluing machines are usually divided into a paper feeding part, a pre-folding part, a bottom-hooking part, a forming part and a box pressing part. The function of the bottom-hooking part is to hook up the bottom side wings of the carton board. The bottom-hooking mechanism uses a claw with an arc at the end to hook the folded carton bottom board. Then, with the conveyance of the cardboard, the hooked bottom board will fit with the inner surface of the carton, thus completing the bottom-hooking process of the carton. When the traditional bottom-hooking component of the carton gluing machine is in use, it is inconvenient to adjust the bottom-hooking component. When folding a single-specification carton on the carton gluing machine, it cannot well meet the folding of cartons with different heights, having certain limitations. Therefore, a carton quick bottom-hooking device is needed. Content of the Utility Model
