Corrugated boxes are the most widely used packaging products, and the amount of use has always been the first among all kinds of packaging products. Corrugated boxes are green and environmentally friendly products, which are convenient for loading and unloading. In the existing technology, some corrugated cardboards need to be slotted before the bending process to facilitate folding into cartons.

[0003] A corrugated cardboard slotting device disclosed in the patent with publication number CN113771113A in the current technology relates to the field of corrugated paper processing technology, including a workbench, an elastic slotting device is arranged above the workbench, the elastic slotting device is connected by a connecting plate, the elastic slotting device drives the connecting plate to move up and down through the rotation of the cam, and then drives the elastic slotting device to reciprocate up and down to realize the slotting action.

[0004] When slotting the corrugated cardboard, there is a lack of a limiting and fixing device for the corrugated cardboard. During slotting, the corrugated cardboard is very likely to deflect, resulting in slotting failure. In addition, the chip collecting groove of the device is under the workbench. After the slotting is completed, the staff needs to manually clean the debris on the workbench and collect it in the chip collecting groove, which increases the workload of the staff. For this reason, we propose a corrugated cardboard slotting device. Utility Model Content
