[0002] A carton is a packaging container made of cardboard, usually used for storing and transporting items. They are lightweight, sturdy, recyclable, etc. During the production process of cartons, it is necessary to slot and die-cut the cardboard. Slotting refers to cutting predetermined slots at the edges or folding places of the carton, which facilitates the folding and assembly of the carton. Die-cutting means cutting the cardboard into specific shapes by using a die (usually a steel knife) to produce cartons in different forms to meet the packaging needs of different products.

[0003] After slotting and die-cutting, the cardboard needs to be neatly stacked by a stacking system for subsequent handling, storage or transportation. However, during the slotting and die-cutting process of carton cardboard, a large amount of waste is generated. These wastes do not have a unified collection and treatment channel. The wastes exist in various gaps of the equipment circulation and are also mixed between the stacked cardboard above and below, which not only affects the normal operation of the slotting and die-cutting equipment, but also affects the flat stacking of the cardboard after die-cutting and slotting.
