Divided from the overall structure and working principle, the domestic blister packaging machines can be generally divided into three series: (I) roller blister packaging machine, On, J, 130 series, main machine 250 series; (2) Roller type blister packaging machine, medium and low speed models (punching times of 60 times / min or less); high speed models (punching times of 80 times / more); (3) flat blister packaging machine.
Blister packaging machine working principle and process
1 roller blister packaging machine
The working principle of the roller blister packaging machine: the forming film is heated and softened by the heating device, and the blister is sucked by the vacuum negative pressure on the roller forming molding roller, and the filling device fills the packaged object into the blister, and then passes through the roller type. The heat sealing device seals the single-sided adhesive-coated cover film on the surface of the blister material at a suitable temperature and pressure, and seals the packaged object in the blister. After printing, the printing unit prints the batch number and presses the broken line, and finally the punching device is punched into a packaging piece of a certain size.
2 flat blister packaging machine
The working principle of the flat blister packaging machine: the formed film is heated and softened by the flat heating device, and the softened film is blown into a blister by using compressed air in the flat forming device, and the filling device fills the package into the blister. Then, it is sent to the flat sealing device, and the cover film is sealed with the formed film at a suitable temperature and pressure, and then the batch number is printed and the broken line is pressed by the typing imprinting device, and finally the punching device is punched into a predetermined size. Packaging plate.
3 roll plate blister packaging machine
The roller plate type blister packaging machine is derived from a roller type and flat type blister packaging machine, that is, a flat type molding device is used for blow molding (positive pressure forming), and a roller type sealing device is sealed, and its working principle and The above two are basically the same.
