It is mainly used to cut the edges of the packaging box and recycle the generated waste. The trimming and recycling device for paper packaging box production usually includes two parts: the trimming mechanism and the waste recycling mechanism. The trimming mechanism is responsible for cutting off the excess edges of the packaging box, while the waste recycling mechanism is responsible for collecting and processing these wastes.
