パッケージフィルム開口亀裂線のロール形成機構およびそのロール形成方法
Document Type and Number:
Japanese Patent JP5138659
Kind Code:
B2
Abstract:
A rolling mechanism for having an opening perforation line on a plastic packaging film is disclosed, including a carriage frame (6), a pressure bearing unit (22), an impact cushioning mechanism (10), and an opening cutter assembly (2). The pressure bearing unit (22) includes a pressure bearing seat (223), an anvil roll (221), and a retention plate (222), wherein the retention plate (222) comprises a receptacle channel (225). The retention plate (222) is used to position the anvil roll (221) in the receptacle channel (225) of the pressure bearing seat (223). The impact cushioning mechanism (10) is coupled between the carriage frame (6) and the pressure bearing seat (223). The opening cutter assembly (2) is arranged adjacent to the anvil roll (221), which includes an opening cutter shaft (20) and at least one opening cutter blade (211) attached to the periphery of the opening cutter shaft (20). The opening cutter assembly (2) is driven to rotate so as to have the opening cutter blade (211) rolling on the anvil roll (221) of the pressure bearing unit (22) and an impact applied to the anvil roll (221) or the pressure bearing unit (22) is absorbed by the impact cushioning mechanism (10).
