A plastic packaging bag die cutting device

Abstract

The utility model relates to packing bag processing equipment technical field especially, it is a kind of plastic packaging bag die cutting device, including upper die assembly, lower die assembly and die cutter, upper die assembly is sequentially provided with upper die seat, upper die base plate and upper die plate from top to bottom;Lower die assembly is sequentially provided with lower die seat, lower die base plate and lower die plate from bottom to top, and die cutting backing plate of PVC material is detachably connected on lower die plate, and its hardness is lower than die cutter;Die cutter is fixed in upper die plate by tool rest, and die cutter is composed of two special-shaped cutters symmetrically arranged on tool rest, and special-shaped cutter is matched with the shape of packing bag semi-finished product.The utility model improves die cutting backing plate material and improves die cutter structure by optimization, effectively reduces cutter wear, simultaneously avoids the problem that burr is generated on product edge, thereby significantly improves the service life and cutting quality of cutter, and further improves the die cutting efficiency of plastic packaging bag.
