The invention discloses an emptying device of rolled packages, which pertains to the field of food packaging machinery and comprises an unwinding guiding device, a detection and wheel falling device, a prestretching and flattening device, a batch feeding wheel and a feeding motor, wherein, the unwinding guiding device is internally provided with roll materials which are transported to the prestretching and flattening device by the unwinding guiding device, the prestretching and flattening device, the detection and wheel falling device and the feeding motor are connected through a circuit, thedetection and wheel falling device is movably arranged under the prestretching and flattening device, the batch feeding wheel is arranged at the back part of the detection and wheel falling device and coaxially connected with the feeding motor, and the roll materials respectively pass through the unwinding guiding device, the prestretching and flattening device and the detection and wheel fallingdevice and then enter the batch feeding wheel. The emptying device can effectively lead the stretching force of the roll materials which enter the batch feeding wheel to be even and smooth, thus improving the cutting stability and the package sending speed of the complete machine.
