Package film opening crack line opening blade module

摘要

An opening cutter assembly (2) forms an opening perforation line in a plastic packaging film by rolling the plastic packaging film between the opening cutter assembly (2) and an anvil roll (221) of a rolling mechanism for having an opening perforation line on a plastic packaging film (100) when the plastic packaging film is fed through the rolling mechanism (100). The opening cutter assembly (2) includes an opening cutter shaft (20), at least one opening cutter seat (21), and at least one opening cutter blade (211). The opening cutter shaft has at least one containing compartment (27) formed. The opening cutter seat (21) is installed in and engaged to the containing compartment (27) of the opening cutter shaft (20) by a cutter seat mounting mechanism (200). The opening cutter blade (211) is mounted to each opening cutter seat (21). When the opening cutter blade (211) gets worn out due to long term operation and must be replaced, simply dismounting the cutter seat mounting mechanism (200) allows the opening cutter seat (21) and the opening cutter blade (211) to be removed out of the containing compartment (27) of the opening cutter shaft (20).
