Blister packaging machine work characteristics
Plate type blister packaging machine operation process and way of working: molding plastic is heated to softening at plate type preheating to remove plastic state, by step remove traction to the plate type forming remove, reduce air will soften hard blow molding of plastic (or stamping molding) into a blister, disassembly will be filling packaging filling into the blister, then transfer to a plate type sealing disassembly, Under the appropriate temperature and pressure, the plastic sheet of the cage cover is sealed with aluminum foil, and finally sent to typing, stamping and punching for disassembly. The batch number is punched out, the broken line is pressed out, and the plate is punched into the specified size. Namely; Molded plastic sheet unwinding → pre-holding → blow molding → material filling → sealing aluminum foil with cage cover → marking batch number → pressure breaking line → stepping → punching cutting → waste collection. In recent years, some drugs need to avoid light packaging, flash a new packaging base material that is composite aluminum foil, it does not need to preheat and shorten the air when forming, but using mechanical stretching system forming.
Features: forming folding and disassembly structure for flat type, forming system for blow molding (positive pressure molding), shortening the air will be heated to soften the plastic hard piece of molding (or blow molding and stamping) molding mold cavity. A blister that forms the desired geometry. With positive pressure forming, is the forming of good quality and high dimensional precision, small part of good reproducibility, transparency, good gloss, blister regards crisp, uniform thickness, forming blister size can be bigger, can draw ratio is big, big blister forming depth can reach more than 35 mm, can produce complex shape of the blister, forming pressure is greater than 4 mpa.
Sealing and disassembly structure is plate type, the aluminum foil material to be sealed is sent to the plate type sealing plate between pressure sealing, after a time after the active separation, belongs to intermittent sealing, surface contact, the total sealing pressure required is large, high precision sealing mechanism request.
Due to plate forming and plate sealing, it has strong compliance to plate size change. Plate enumeration is agile. The plate cut out is flat and not warped. But the sealing time is long, so that the speed of the machine falls, the individual punching times within 35 times/min. This kind of advantage type can fill gas larger, can be installed at the same time, more easily realize a plate to pack a variety of drugs packaging, expand the packaging scale, advanced packaging grade.
