Description

Technical Field

[0001] The utility model relates to the technical field of corrugated carton processing, and specifically relates to a corrugated carton cutting mechanism. Background Art

[0002] Corrugated paper, also known as kraft paper and paperboard, is a common material for paper packaging boxes. It is lighter than wooden boxes and has hardness, and is easy to cut in size. It is used to protect other products being packaged from damage. When corrugated cartons are processed and produced, a complete large corrugated cardboard needs to be cut into multiple small corrugated cardboard pieces of appropriate size by a cutting device, and then further processed.

[0003] The patent with the publication number CN220332110U proposes a cutting device for carton production, including: a cutting workbench surface, one end above the cutting workbench surface is fixedly connected with a cutting machine cabinet, one end below the cutting machine cabinet is provided with a hydraulic telescopic rod, one end of the hydraulic telescopic rod is fixedly connected with a pressing and limiting groove plate, one end of the pressing and limiting groove plate is telescopically connected with a rubber pressing plate, one end of the rubber pressing plate is fixedly connected with a telescopic rod, a telescopic spring is sleeved outside the telescopic rod, and a cutting knife is arranged at the other end below the cutting machine cabinet; in the utility model, two groups of hydraulic telescopic rods are used to press down the pressing and limiting groove plate and the rubber pressing plate. When the rubber pressing plate fits the cardboard, the telescopic rod and the telescopic spring are stressed and contracted, which can play a certain limiting effect on the cardboard and can also play a good buffering effect to prevent the cardboard below from being crushed. At this time, starting the cutting knife to press down for cutting can realize the cutting work of the corrugated cardboard.

[0004] In the above case, when pushing the corrugated cardboard to adjust the cutting length of the cardboard, although the side of the cardboard can be limited by the cardboard guide groove, when the staff pushes multiple neatly stacked corrugated cardboards, it is easy to cause the problem that the front and back surfaces of the originally neatly stacked corrugated cardboards are uneven. After cutting, it is easy to cause the problem that the lengths of each corrugated cardboard are inconsistent, thereby reducing the cutting quality of the corrugated cardboard. For this reason, this application proposes a corrugated carton cutting mechanism. Content of the Utility Model
