Storage shelf structure

The invention relates to a storage shelf structure which comprises a rack. A guide roller fixing frame is arranged on the rack and provided with multiple fixed guide roller sets. Each fixed guide roller set comprises multiple fixed guide rollers. A movable frame is arranged on the rack, moves relative to the guide roller fixing frame and is provided with multiple movable guide roller sets opposite to the fixed guide roller sets. Movable guide rollers are arranged on the movable guide roller sets. Traction devices driving the movable frame to horizontally move back and forth are arranged between the guide roller fixing frame and the movable frame. According to the storage shelf structure, a three-layer guide roller structure is adopted, the number of layers of punctured films is larger, the structure is more compact, the storage length is increased, and more materials can be stored; a double-floating-roller structure is adopted, tension change can be better buffered in the material receiving process, and the out of register influences caused by sudden change of tension in the material receiving process on printing are reduced.
