[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] As shown in the figure, the back-adhesive slitting machine of this embodiment includes a frame 1, on which are provided a sponge rubber belt unwinding shaft 2, a double-sided tape unwinding shaft 3, a back-adhesive unit, a guide shaft 4 for respectively guiding the sponge rubber belt and the double-sided tape into the back-adhesive unit, a slitting unit and a winding shaft 5.

[0018] The adhesive backing unit includes a pressure-bearing roller 6 whose two ends are rotatably connected to the frame, a pressure-applying roller 7 located above the pressure-bearing roller, a guide block 8 rotatably connected to the end of the pressure-applying roller, and a cylinder 9 arranged on the frame and whose piston rod end is connected to the slider. The guide block is slidably matched with the frame up and down.

[0019] The slitting unit includes a transverse guide rail 10 arranged on the frame and parallel to the axial direction of the pressure roller, a connecting seat arranged on the transverse guide rail and capable of adjusting its position along the transverse guide rail, a knife rod 11 arranged on the connecting seat and capable of adjusting its position up and down, a U-shaped head 12 arranged on the lower end of the knife rod, and a circular cutter 13 arranged on the U-shaped head.

[0020] In this embodiment, a rectangular guide groove is provided on the transverse guide rail, and the connecting seat includes a seat body 14 and a back plate 15 located at the front and rear sides of the transverse guide rail. The seat body is provided with a rectangular embedded portion 141 that slides with the rectangular guide groove and a waist-shaped guide hole 142 that slides up and down with the knife bar. The back plate and the seat body are connected by screws, and the seat body is also provided with screws for fixing the knife bar. In this embodiment, the installation position of the connecting seat can be adjusted along the transverse guide rail, and the position of the knife bar can be adjusted up and down along the waist-shaped guide hole, so that it can adapt to cutting sponge rubber sealing belts of different widths and thicknesses in actual work.
