Description

Technical Field

[0001] This utility model relates to the field of cardboard creasing technology, specifically to an automatic adjustment mechanism for a cardboard creasing machine. Background Technology

[0002] Cardboard creasing is a process that uses specialized creasing equipment to apply pressure to cardboard, creating indentations or raised lines on its surface. During the creasing process, the cardboard is subjected to two pairs of shear forces on both sides of the fold groove, and is also compressed under the pressure of the steel wire. In addition, the outer layer of the cardboard is subjected to tensile force, and the inner layer is subjected to compressive force. Under the combined action of these three forces, the molecular bonds between the contacting fiber surfaces in the internal structure of the cardboard are disrupted, and irreversible displacement occurs between the fiber surfaces, thus forming permanent indentations.

[0003] Traditional cardboard creasing equipment uses a fixed installation method for its pressure rollers, which makes it inconvenient to quickly move and adjust the position of the pressure rollers during use.

[0004] To address the aforementioned problems, we propose an automatic adjustment mechanism for a cardboard creasing machine. Utility Model Content
