Description

Technical Field

[0001] The present invention relates to the field of carton processing, including the technical field of carton forming machines, and in particular to a knife group for processing cardboard into packaging cartons and a carton machine having the knife group. Background Art

[0002] In the existing technology, the CNC equipment for processing small batches of loose orders and carton processing that does not require molds currently mainly includes carton forming machines and proofing machines. Proofing machines can process cartons of any shape, but their processing efficiency is particularly low and the pressing line forming effect on thick cardboard is poor; carton forming machines have high processing efficiency and good pressing line forming effect, but they cannot process cartons with complex curves or oblique lines (processing simple curves or oblique lines requires a knife die to complete).

[0003] In the prior art, for example, patent documents CN 116638820 A and CN 220242538 U both involve carton processing and forming technology, but they do not have the function of processing curves and oblique lines, and cannot achieve efficient processing of carton forming with curves and oblique lines. Although patent documents CN 105291176 A and CN 205660840 U disclose a vibrating knife structure, they do not have a driving structure compatible with a carton forming machine. Summary of the invention

[0004] The present invention is based on a carton forming machine, and can process more complex box types such as oblique lines or curves while ensuring processing efficiency and processing quality. In addition, relying on the transmission system of the carton forming machine, it is not necessary to use negative pressure suction during the processing (in order to ensure the processing effect during the proofing machine processing, the cardboard needs to be adsorbed on the platform through negative pressure suction, the cardboard is stationary, and the cutter moves for cutting). The present invention cuts the cardboard during its movement, and the cardboard is flattened by the paper pressing structure of the carton forming machine and the paper pressing mechanism on the vibrating knife die set to ensure the cutting effect. Negative pressure suction is not used, the structure is simpler, and the cost is lower.
