The invention discloses back-
cutting rewinding equipment which comprises a nicking tool, a finished product winding shaft and a waste winding shaft, wherein the nicking tool is used for
cutting off back paper along the central symmetric line in the length direction without touching
adhesive paper, the finished product winding shaft is used for collecting
cut-off back paper and the
adhesive paper,and the waste winding shaft is used for collecting transparent films separated from the back paper and the
adhesive paper. The finished product winding shaft is composed of a shaft core and a baffle plate at one shaft end, the baffle plate is provided with an annular tapered surface capable of conveniently guiding the back paper and the adhesive paper to enter the finished product winding shaft, and one sides of the back paper and the adhesive paper abut against the baffle plate for rewinding; a
blind hole is formed in the center of the baffle plate, the shaft core is inserted into the
blind hole to be matched with the
blind hole, and the depth of the blind hole is half of the value obtained by subtracting the width of the back paper or the adhesive paper from the
axial length of the shaftcore; and the shaft core is provided with an openable limiting rod capable of applying elastic pressure to the shaft core, when the limiting rod is in a
closed state, the shaft core and the baffle plate are limited and fixed, and a separating path is provided for the shaft core when the limiting rod is opened and closed. By adopting the back-
cutting rewinding equipment, separation and collectionof coiled materials with different
layers can be facilitated, and meanwhile, specific coiled materials are
cut off, so that the efficiency and the quality of cutting and collecting are guaranteed.
