The flat plate structure of blister packing machine

Plate type blister packaging machine operation process and execution of work: molding plastic is heated to softening at plate type preheating to remove plastic state, servo traction to the plate type forming disassembly, dominating shorten air will soften hard blow molding of plastic (or stamping molding) into a blister, remove the filling materials will be filling into the bubble, and then transfer to a plate type sealing removal, at the appropriate temperature and pressure, will cover plastic plate and aluminum foil sealing, then sent to the typing, stamping and punching disassembly, with batch number, pressure out of the broken line, cutting into a regulation the size of the plate. That is, molding plastic hard sheet unwinding → preheating → blow molding → material filling → sealing aluminum foil → batch number → pressure break line → servo → punching and cutting → waste collection. Some drugs need to avoid light packaging, the emergence of a new packaging substrate that is composite aluminum foil, it does not need to preheat and shorten the air in the molding, but the use of mechanical drawing of the system.

The forming disassembly structure is flat, and the forming system is blow molding (positive pressure molding). The heating and softening molding plastic hard piece is blown into the cavity of the molding mold by dominating the shortening air (or blow molding and stamping), and the required geometric shape of the bubble cap is formed. 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 is larger, the draw ratio can be bigger, blister forming great 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 material to be sealed aluminum foil is sent to the plate type sealing plate and then pressurized sealing, after a press time, activated separation, belongs to intermittent sealing, surface contact, the total sealing pressure is large, the sealing mechanism precision request is high. Due to the use of plate forming, plate sealing, so the size of the plate change adaptability, plate listing agile, punching out of the plate flat, no warping. But the seal should always fight long, so that the machine speed down, the number of individual punching within 35 times/min. This type of machine has a large filling space and can be equipped with multiple filling machines at the same time, which can easily realize the packaging of a variety of drugs in one plate, thus expanding the packaging scale and advancing the packaging grade.
