The utility model provides a firecracker winding drum machine which comprises a paper winding drum machine, a support is installed on the paper winding drum machine, a shaft rod is connected to the support, the shaft rod is rotationally sleeved with a retractable sleeve shaft mechanism, and damping rotation is achieved between the retractable sleeve shaft mechanism and the shaft rod. A buffering abutting mechanism is installed on the support. According to the firecracker winding drum machine, through the arrangement of the paper winding drum machine, the support, the shaft rod, the contraction type sleeve shaft mechanism and the buffering abutting mechanism, a paper roll can rotate around the same axis all the time in the feeding process, it is guaranteed that the tension of paper is stable in the feeding process of the paper roll, and therefore the quality of a paper winding drum is guaranteed; the paper conveying device can adapt to paper rolls with different inner diameters, and the tensioning force requir
