When in work: a coil material 8 is placed on the unreeling shaft 1, the transverse position is adjusted according to the position of an infrared alignment sensor 10, one side of the coil material 8 is aligned with infrared rays, and the coil material is locked after being aligned. The material roll 8 is unfolded according to the unfolding direction, passes through a relevant traction mechanism and a relevant guide roller according to a paper passing route, and finally, the paper head is attached to the winding shaft 2 by using an adhesive tape. Because the detection mechanism is at a certain physical distance from the winding shaft 2, if the unwinding end of the material roll 8 is directly attached to the winding shaft 2, the material roll 8 from the detection mechanism to the winding shaft 2 cannot be detected, so that when the device is just started, the waste material is firstly adopted to be in butt joint with the paper head at the initial end of the first material roll, and at least the waste paper is adopted to be in butt joint at the distance from the detection mechanism to the winding shaft 2, so that the camera 52 can start shooting.
