[0002] Medical packaging printing is a controlled process that accurately transfers information such as text, graphics, barcodes, and anti-counterfeiting to the inner and outer packaging materials of pharmaceuticals, aiming to ensure compliance, safety, and traceability throughout the life cycle of pharmaceuticals. To ensure safety, food-grade, non-migratory environmentally friendly inks are often used to avoid chemical reactions with pharmaceuticals or the release of harmful substances. The slitting cutter head subassembly of medical packaging printing is a core mechanical component that precisely slits printed medical packaging materials (such as pharmaceutical aluminum foil, composite film, paper box paperboard, etc.) into specified sizes. It is a key equipment component in the post-printing processing link, and its performance directly affects the slitting accuracy, edge quality, and production efficiency of packaging materials, and needs to meet the stringent requirements of the pharmaceutical industry for material cleanliness and size consistency. The slitting cutter head subassembly drives the hard alloy round knife to rotate at high speed to slit medical packaging. However, during slitting, the micro-chips, paper powder, and ink particles generated when cutting aluminum foil, composite film, or label substrate cannot be promptly extracted, and thus may fall onto the printed surface or adhesive layer, forming visible defects such as white spots, black spots, and indentations, thereby reducing the yield of the production line, increasing the risk of quality and scrap costs.
