Material rack suitable for placing lithium ion battery material rolls

The material rack comprises a supporting frame, a sliding rail is installed on the supporting frame, a plurality of material roll supporting assemblies are installed on the sliding rail in a sliding mode, placing positions used for placing material rolls are arranged on the material roll supporting assemblies, and the material roll supporting assemblies are connected with the sliding rail in a sliding mode. The material roll supporting assembly slides on the sliding rail and is used for adjusting the distance between every two adjacent containing positions. By the adoption of the technical scheme, the material roll placing device is ingenious in conception and reasonable in structure, produced material rolls can be placed through the material roll supporting assembly, the material roll supporting assembly can freely slide on the sliding rail so that the spacing distance between every two adjacent material rolls can be adjusted, the produced material rolls can be placed in sequence, and the production efficien
