[0002] Packaging boxes are widely used. In order to meet the application requirements of decoration, protection, etc., many packaging boxes need to be pasted with surface paper and other processes. For example, bottled wine packaging boxes need to be pasted with surface paper printed with pictures and texts on the basis of hardboard (usually cardboard), and adhesive is applied between the two. Or, the packaging box itself includes an inner box and an outer box bonded to each other. In order to avoid bubbles in the interlayer between the surface paper and the cardboard or between the cardboard and the cardboard, which may affect the bonding quality, the bubbles need to be pressed out by bubble pressing equipment.
