[0058] Reference Figure 3A heating plate is fixed on the upper end of the limit plate 34, and the heating plate is suitable for abutting against the side wall of the cutter 33, and the heating plate is suitable for heating the cutter 33. The heating plate can transfer heat to the cutter 33. When the side wall of the cutting edge of the cutter 33 abuts against the inclined surface 45 of the horizontal plate 44, the heat on the cutter 33 is suitable for being transferred to the fracture of the aluminum-plastic film. The side wall of the cutting edge squeezes the aluminum-plastic film, and the temperature on the cutter 33 cooperates with each other, which can avoid the fracture of the aluminum-plastic film from being delaminated.
