The invention discloses a switching-type barrier-free energy-saving material storage device. The switching-type barrier-free energy-saving material storage device comprises a rack and further comprises an unwinding mechanism A, an unwinding mechanism B, a switching mechanism, a material storage device body A, a material storage device body B, an active traction device and a deviation correcting device which are arranged on the rack. A plurality of material transition rollers are arranged on the rack in the rolling paper conveying direction. According to the switching-type barrier-free energy-saving material storage device, the unwinding mechanisms are adjusted to keep the same linear speed with the active traction device through swinging arms of the material storage device body B, and thusthe problem that materials are excessively loosened or excessively tightened in the conveying process is avoided; and in a working state of no stored material, two material storage fixing frames of the material storage device body A are always in a closed state, rolling paper does not need to be driven to be conveyed by idler wheels on the material storage fixing frames, the materials only pass through the shortest distance, rotation of the idler wheels is reduced, the working time of bearings and the idler wheels is shortened, in this way, friction can be reduced in a large area mode, the maintenance time of components is shortened, the maintenance cost of the components is lowered, the service life is prolonged, deformation of the materials due to friction force in the conveying processis reduced by a large margin, and thus the purposes of high finished product rate and less resource waste are achieved.
