Abstract

The utility model discloses a combined type adhesive film punching die, which relates to the field of adhesive film punching and comprises a punching base, a movable plate arranged above the punching base, two symmetrical fixed plates arranged above the movable plate, a plurality of second punching shear heads and a plurality of first punching shear heads arranged inside the movable plate, according to the punching and shearing device, by arranging the spray head, when the first punching and shearing head and the second punching and shearing head conduct alternative punching, the inner wall of the punching and shearing groove which does not work can be cleaned, the cleanliness of the inner wall of the punching and shearing groove is guaranteed in the punching process, and the punching and shearing efficiency is improved. The glue on the glue film is prevented from being adhered to the inner wall of the punching and shearing groove, and the punching and shearing groove and the punching and shearing cutter head can be damaged by long-time punching and shearing work, so that the glue adhered to the inner wall of the punching and shearing groove can be automatically cleaned during working, the function of self-cleaning while working is realized, regular shutdown for cleaning the die is not needed, and the working efficiency is improved. And the precision of the die under the long-time use condition is ensured.
