Cutting fixture for heat-shrink film sleeve labeling machines

摘要

An improved cutting fixture for heat-shrink film sleeve labeling machines comprised of a mounting frame disposed around the outer periphery of the center guide post in a sleeve labeling machine that secures a plurality of blade assemblies at equal intervals apart. Each blade assembly is positioned on a drive plate by means of an inserted eccentric shaft to maintain synchronous operation. The eccentric shafts of the blade assembly are driven into reciprocal rotation by a power structure, each eccentric shaft causing the blades at their lower extents to alternately project and retract for cutting heat-shrink film at a required travel and time to effectively shorten the period involved and thereby increase production efficiency. Each cutter shaft is restrained by a check plate and anchoring screws to prevent 360 -degree free rotation, which not only results in safer blade replacement, but at the same time also prolongs the service life of the transmission and structural components.
