Therefore, in the application, since the lower roller 14 and the guide plate 15 are elastically slidably arranged, and the elastic sliding resistance of the guide plate 15 is smaller than the elastic sliding resistance of the movable plate 12, when the material is continuously loosened, the upper roller 13 can squeeze the lower roller 14 to move downwards so as to keep the finished product material 601 in a squeezed state all the time, when the upper roller 13 moves downwards to a limit state, the material is cut off, and the finished product material 601 is still pressed between the upper roller 13 and the lower roller 14, so that the material positioned at the upstream of the cutting position after the finished product material 601 is cut off can not be loosened, the material 201 to be processed can not be separated from the adhesive layer and the release paper layer, the working complexity can be greatly reduced, the operation time can be shortened, the working efficiency can be improved, and the technical problems can be effectively solved.
