Loosened storage material feeder

The utility model relates to a loosened storage material feeder which comprises a frame, a storage case, a rear conveyer belt, a front conveyer belt and a driving mechanism, wherein the upper part of the front conveyer belt is provided with at least two loosened roller sets, and each loosened roller set provided with harrowing nails at the periphery is supportably connected to the frame. A motor is connected with the loosened roller sets through the driving mechanism, and material passing space is arranged among the loosened roller sets. When softened tobacco sheet packages or blocks are sent to a dampening machine for humidifying and heating, the loosened roller sets in the storage case of the material feeder, which are driven by the motor, separate the tobacco sheet packages or blocks continuously through the harrowing nails so as to completely loosen the tobacco sheet packages and blocks. The production efficiency is raised, and various production capacities are satisfied. The utility model has advantages of simple technology, reliability, and decreased broken rate of tobacco sheets.
