[0002] As the name suggests, a packaging box is a box used to package products. Yellow corrugated paper is a common material for packaging boxes. In order to classify and package products and improve the appearance and grade of products, some beautiful patterns, introduction texts, trademarks, etc. are printed on the packaging boxes. When printing on the packaging boxes, the existing printing device places the cut packaging box cardboard neatly on the conveyor belt, and the conveyor belt conveys the packaging box cardboard to the bottom of the printing part, and the printing part prints the patterns, texts, etc. on the packaging box cardboard.
