Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cardboard cutting device used for paper box production. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body with high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself. In the production process, a cutting device is usually used to cut the corrugated cardboard.

[0003] A Chinese patent with publication number CN217801881U discloses a cutting device for processing corrugated cardboard, including a workbench, a cutting assembly is arranged on the workbench, a limiting assembly for fixing the corrugated cardboard is arranged inside the cutting assembly, and a dust removal device for collecting cut paper scraps is arranged at the bottom of the workbench. By starting the motor, the movable block and the roller move in a direction away from the motor, so that the roller gradually presses the movable plate downward during the movement, thereby driving the U-shaped pressing plate to move downward until the corrugated cardboard on both sides of the cutting groove is pressed tightly, which can avoid the displacement and warping of the corrugated cardboard during the cutting process, thereby reducing the cutting error. By arranging the dust removal device, the paper scraps generated during the cutting process can be collected into the dust removal device through the dust cover and the air duct, thereby avoiding the paper scraps flying in the workshop or accumulating on the workbench, which affects the subsequent cutting.

[0004] In the above technical solution, the limiting components are provided at both ends of the workbench. When the cardboard is small, the two ends of the cardboard cannot be fixed, which causes the cardboard to easily shift during the cutting process and the cutting effect is poor.

[0005] Based on this, the utility model proposes a cardboard cutting device for paper box production. Utility Model Content
