Description

Full-automatic boxing production line for bottom-hooking gift boxes and boxing method thereof Technical Field The invention relates to full-automatic packaging of high-end beverage gift boxes, in particular to a full-automatic boxing production line of a bottom-hooking gift box, and further relates to a full-automatic boxing method of the bottom-hooking gift box. Background For many years, the packaged products such as packaging boxes, packaging boxes and the like are directly sent to a client by a commercial truck, and then are stacked on a tray again for warehouse entry after being unloaded by the client. Along with the continuous upgrading and reconstruction of the intelligent workshops by using terminal clients, new requirements are also put forward on the delivery mode of suppliers, namely, the suppliers must pre-load products such as cartons, gift boxes and the like into special turnover boxes according to the workshop demands of users, and then send the products to the users together with the turnover boxes, and the users can directly send the turnover boxes sent by the suppliers to a full-automatic packaging assembly line through an intelligent production line for automatic packaging operation. At present, a manufacturer of gift boxes generally adopts a sequential stacking mode after folding 50 gift boxes, and manually loads the gift boxes into a turnover box for transportation. Because the turnover box is of a flat rectangular structure, the turnover box is flat and integral after stacking, and the robot operation is very convenient. The bottom-hooking gift box is the preferred packaging mode of high-end milk products or other drinks. The gift box adopts a forming mode of combining the bottom hooking and the adhesive, so that the load effect is good, and the gift box can be formed by pushing two ends of the gift box to the middle when in use, thereby being extremely convenient for the operation of a full-automatic packaging line. But the bottom-hooking gift box adopts an automatic forming mode of combining the bottom hooking and the adhesive, so that the bottom needs to be repeatedly folded positively and negatively, so that the number of the paperboards at the bottom of the gift box formed by folding is up to 6, the number of the paperboards at the upper opening is only 2, the structure of a single bottom-hooking gift box after folding is shown in fig. 7, the vertical thickness is greatly different, and the structure with a trapezoid vertical section is formed. Under normal conditions, 50 gift boxes are required to be assembled in one turnover box, if a conventional sequential stacking mode is adopted, the 50 gift boxes with hooked bottoms are folded and then are put together as shown in fig. 8, the bottoms of the gift boxes are tightly attached together to reach 400mm, gaps of four layers of paperboards are reserved between two adjacent gift boxes at the upper opening part, that is to say, 2/3 of the gaps are reserved, the 50 gift boxes with hooked bottoms cannot be normally clamped and put into the turnover box by a common mechanical arm, so that the turnover box can only be assembled by adopting manual operation for multiple times, the labor input cost is huge, the workload is large, the efficiency is low, and the timeliness of goods supply and the satisfaction rate of the quantity of the goods supply cannot be met. In order to realize the automatic operation of the bottom-hooking gift box, the development of a full-automatic bottom-hooking gift box boxing production line is very necessary for production enterprises. Disclosure of Invention The invention aims at providing a full-automatic boxing production line of the bottom-hooking gift box aiming at the structural form of the bottom-hooking gift box so as to realize the technical requirement of automatic boxing of the bottom-hooking gift box, and simultaneously provides a full-automatic boxing method of the bottom-hooking gift box. In order to achieve the above purpose, the present invention may adopt the following technical scheme: The full-automatic boxing production line for the bottom-hooking gift boxes comprises a gift box separation unit, a quality control unit, a counting unit, a folding unit, a boxing unit, a gathering unit and a stacking output unit which are sequentially connected through a conveying roller way; the gift boxes which are sequentially staggered and stacked and output from the outlet of the box gluing machine are separated into independent single gift boxes through a separation unit, the independent single gift boxes sequentially enter a quality inspection unit for quality inspection, the independent single gift boxes are counted through a counting unit and are arranged into standard stacks and then are conveyed to a stacking unit, the stacking unit is used for collecting and integrating a plurality of standard stacks according to the capacity of the turnover box and then conveying the standard stacks into a boxing uni
