Description

Packaging box production equipment and production method based on edge milling avoidance Technical Field The invention relates to the technical field of packaging box production equipment, and particularly discloses packaging box production equipment and a packaging box production method based on edge milling and avoidance. Background The packing box, especially for high-end gift, electronic product and cosmetic, is usually made of a composite cardboard formed by pasting a gray board and facial tissues, and is made into a box body through die cutting, folding, bonding and other procedures. In order to improve the appearance quality of the packaging box, higher requirements are often put forward on the corner flatness, the lug plate attaching degree and the corner sharpness of the box body. In the existing packaging box production process, aiming at the problem of overlapping of corner thicknesses in the folding and forming process, a mode of cutting and avoiding treatment on a die-cut gray board layer and then laminating with a face paper layer is generally adopted to form a space compensation structure in a folding area. However, the process has higher requirements on the cutting precision and mounting alignment precision of the gray plate, once the cutting size or mounting position is deviated, the problems of bulge of the lug plate, uneven corners and the like are easily caused during subsequent folding and forming, and thus, the reject ratio of the finished product is higher. In addition, although the existing partial packaging box forming equipment is provided with a slotting mechanism for forming a slot structure at the folding position of the paperboard to guide folding, slotting treatment of this type is generally only used for realizing folding action, and is difficult to effectively solve the problem of appearance defects of laminated composite paperboards in the folding process due to superposition of material thicknesses, and corners of the folded box body still easily present arc shapes to influence the overall visual effect. Therefore, the prior art still lacks a packaging box production device and a packaging box production method which can be suitable for laminated composite paperboards and can still effectively improve the appearance quality of folding molding under the condition of independent cutting of high-precision gray boards, so as to realize the molding effect of the packaging box with flat ear plate areas and clear corner edges. Disclosure of Invention In order to overcome the defects and the shortcomings in the prior art, the invention aims to provide packaging box production equipment for realizing flat ear plate areas and clear corner angles. The packaging box production equipment comprises a feeding unit, a side milling unit, a glue melting unit and a forming unit, wherein the feeding unit is used for sequentially conveying an external paperboard to the side milling unit, the glue melting unit and the forming unit, the side milling unit is used for carrying out local milling treatment on the ear plate of the paperboard and/or a folding area of a side plate adjacent to the ear plate, the glue melting unit is used for carrying out glue application on the milling position of the side milling unit, and the forming unit is used for folding and bonding the glued paperboard to form a packaging box body of the packaging box. According to the invention, through arranging the feeding unit, the edge milling unit, the glue melting unit and the forming unit and arranging the feeding unit, the edge milling unit, the glue melting unit and the forming unit in a line mode sequentially according to the processing sequence of the paper board, the edge milling avoidance, glue applying and folding forming processes of the paper board are continuously completed under the same production path. Under the condition that the ash plate layer is not required to be cut independently with high precision, the problems that the laminated composite paperboard is easy to bulge in the ear plate and the corners are circular in the folding and forming process can be effectively solved, the ear plate area of the formed packaging box is smooth, the corners and the corners are clear, and the appearance quality and the forming consistency of the packaging box are obviously improved. Further, the edge milling unit comprises an edge milling platform, a displacement mechanism arranged on the edge milling platform, a positioning assembly and a main shaft assembly connected with the output end of the displacement mechanism, wherein the positioning assembly is used for limiting the paperboard carried by the edge milling platform to avoid displacement of the paperboard, the displacement mechanism drives the main shaft assembly to be close to the paperboard, and the main shaft assembly locally mills the lug plates and/or the side plates of the paperboard. The structure enables the milling position to be controllable and the p
