Finished product of electrolytic copper foil is generally in roll shape, and the roll core is supported by paper tube, and the width of lithium battery copper foil finished product is about 100-700mm, and the weight is several kilograms to hundreds of kilograms. In the transportation process, the roll-shaped finished product copper foil is generally transported by a packaging wooden box that can place several rolls of roll-shaped copper foil.

[0003] The traditional packaging box for transporting roll-shaped copper foil is composed of a base and a cover clamped on the base, and recessed brackets for placing roll-shaped copper foil roll core paper tubes are formed on the corresponding two side walls of the base. For example, a wooden copper foil packaging box is disclosed in Chinese patent CN209667678U. The roll-shaped copper foil to be transported is placed in the recessed brackets of the base, and since there is no baffle on the outer side of the recessed brackets on the base and there is no structure to limit the longitudinal movement of the copper foil in the length direction of the inner side of the cover, the roll-shaped copper foil cannot be completely fixed longitudinally and transversely. The packaging box with this structure will cause the roll-shaped copper foil to collide with the box wall or the adjacent roll-shaped copper foil to collide with each other during transportation, resulting in deformation, wrinkling and copper foil roll of the roll-shaped copper foil during transportation, which affects the product quality. Since the copper foil roll is heavy, it will also pierce the wooden box during handling or transportation translation, causing damage to the box and the copper foil, and causing unnecessary losses to the copper foil production enterprises. SUMMARY
