[0002] Packing boxes are mainly designed to facilitate transportation, loading and unloading, and storage. Wooden boxes and corrugated solid wood pallets are generally used, and tin drums or galvanized iron drums are also used. Honeycomb paper boxes are made by punching, cutting, and pasting honeycomb paperboard. Paper corner guards are pasted on the paperboard interfaces for reinforcement. They can be designed into different configurations such as integral, modular (detachable), and integrated bottom support according to actual needs. They are more conducive to handling, loading and unloading. They are light in material and have a high load-bearing capacity. They can be customized according to the size and specifications of the items. They are mainly used to replace wooden boxes for transportation. Compared with wooden boxes, they have high cushioning performance, lighter weight, faster assembly, time-saving and labor-saving, exquisite workmanship, good sealing performance, and can save a lot of wood resources.

[0003] After the items are packed in the packaging box, the packaging box will be weighed to calculate the total weight of the items and the packaging box, and the items will be classified and stored according to the weight. For example, Chinese patent announcement No. CN213397324U discloses a "weighing and measuring device for plastic packaging box production", which is provided with a movable box on the front of the weighing platform, and the movable box is provided with a motor box, a rotating motor, a rotating bearing and a rotating screw, so that the rotating screw can rotate inside the movable box through the rotating motor and the rotating bearing, and a movable shaft is connected to the outer thread of the rotating screw so that the movable shaft can move left and right outside the movable box through the rotation of the rotating screw, thereby utilizing the extension rod and the connecting rod to drive the transverse plate to move left and right on the top of the weighing platform, and a brush is provided at the bottom of the transverse plate so that the movable transverse plate can clean the top of the weighing platform through the brush;
