The working principle of different types of blister packaging machines
1, roll 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 out by vacuum negative pressure on the roller forming mold. The filling device fills the packaged material into the blister, and then passes the roller The heat-sealing device seals the adhesive-coated cover film on the surface of the blister material under suitable temperature and pressure, and seals the packaged object in the blister, and then the punching device punches into Products of a certain size.
2, flat blister packaging machine
The working principle of the flat-plate blister packaging machine: the formed film is heated and softened by the flat-plate heating device. In the flat-plate forming device, compressed air is used to blow the softened film into a blister. The filling device fills the package into the blister. Then it is sent to the flat-plate sealing device, the cover film and the forming film are sealed under suitable temperature and pressure, and then the batch number is printed by the imprinting device, and then the punching device is punched into product plates of the specified size.
3, roller plate blister packaging machine
The roller-plate blister packaging machine is developed on the basis of the roller-type and flat-plate blister packaging machine. It uses a flat-plate molding device for blow molding (positive pressure molding) and a roller-type sealing device for sealing. The working principle is basically the same as the above two.
