[0002] A paper box is a three-dimensional shape. It is composed of a polyhedron formed by the movement, stacking, folding and surrounding of several surfaces. The surfaces in the three-dimensional structure play the role of dividing the space in space. Cutting, rotating and folding the surfaces in different parts will result in different emotional expressions. The composition relationship of the display surface of the paper box should pay attention to the connection between the display surface, side, top and bottom, as well as the setting of packaging information elements. In the processing of paper boxes, they need to be laminated, so a laminating machine is needed to process them. Laminating machines can be divided into two categories: instant laminating machines and pre-coating laminating machines. After being pressurized by rubber rollers and heating rollers, they are combined to form a paper-plastic integrated product. At present, during the operation of the laminating machine, the cardboard needs to be lifted to a position as high as the conveyor belt, so that it is convenient for external equipment to guide the cardboard onto the conveyor belt.
