[0002] Corrugated box is a box made of corrugated cardboard after die-cutting, slotting, creasing, nailing or gluing. In addition to its functions of protecting goods, warehousing, storage and transportation, corrugated boxes also play the role of beautifying goods and promoting goods. Corrugated box is a green and environmentally friendly product that is beneficial to the environment and easy to load and unload. The processing of die-cutting and slotting usually produces a large amount of waste edges. There are two common ways to collect waste edges, one is manual collection and the other is mechanical collection. The problem with manual collection is that it is time-consuming and labor-intensive. Not only is the collection process inefficient, but it is also inconvenient to pack and organize. Mechanical collection has the problem of incomplete collection. Old corrugated cardboard has different shapes under the condition of waste and occupies a large space. If it is directly pulped, it is easy to damage the machine. Moreover, it is difficult to uniformly treat cardboard of different thicknesses and shapes. If the surface is hard due to the influence of the external environment, it will also damage the machine. Therefore, it is necessary to apply waste cardboard under various conditions to process it more perfectly.
