Cutting fixture for heat-shrink film sleeve labeling machines

A cutting fixture for a heat-shrink film sleeve labeling machine comprising:

• a mounting frame disposed about a center guide post;
• a plurality of blade assemblies coupled to said mounting frame spaced one from the other around the center guide post, each said blade assembly including a cutter shaft and an eccentric shaft extending therefrom, each said blade assembly having a blade extending radially from said cutter shaft and an anchoring screw disposed adjacent thereto, at least a first of said blade assemblies being driven by direct connection to a power structure;
• said power structure including a timing gear engaging said first blade assembly for imparting a driving force thereto, whereby said first blade assembly is reciprocally rotated within a settable angle limit;
• a drive plate extending between said eccentric shafts of said blade assemblies for transferring the driving force between said blade assemblies, said blade assemblies being operably coupled thereby for reciprocal rotation in substantially simultaneous manner;
• and,
• a check plate coupled to said mounting frame and extending between said cutter shafts of said blade assemblies, the said check plate having a plurality of corresponding holes respectively receiving said cutter shafts, and a plurality of limit grooves each spaced radially from and extending arcuately about a respective one of said corresponding holes, each said limit groove slidably receiving said anchoring screw of one said blade assembly for maintaining the reciprocal rotation thereof within the settable angle limit.
