Description

Technical Field

[0001] The utility model belongs to the field of carton processing, relates to a carton creasing technology, and specifically is a carton creasing device. Background Art

[0002] Carton creasing refers to the process of using steel wire to press marks or leave grooves for bending on paper or cardboard through embossing. This ensures that the carton can be folded smoothly during packaging and maintains the desired appearance. It also prevents the cardboard from breaking, cracking or excessive deformation during the folding and creasing process, thereby improving the processing accuracy and durability of the cardboard.

[0003] The reference patent name is: A carton creasing device (patent announcement number: CN221090114U). A creasing wheel and a creasing plate that can be moved downward are arranged above the carton placement seat. After the creasing wheel deepens the indentation on the carton surface, the creasing plate is moved downward to fold the carton, so as to avoid the crease spreading during folding, causing the crease to expand and affect the overall appearance of the cardboard, and make the crease more beautiful and precise.

[0004] However, when implementing the above technical solution, the following problems exist: the above device requires multiple operations to achieve complete folding, and the indentation wheel and the indentation plate are moved to the indentation position in batches to deepen the indentation and fold. However, it is difficult to ensure that the indentation plate completely overlaps with the indentation during the movement, and multiple debugging may be required. Moreover, a single groove on the surface of a single carton requires at least two operations to complete the folding. There are relatively many steps, which greatly prolongs the time for carton creasing.

[0005] Therefore, the utility model provides a carton creasing device. Utility Model Content
