Introduction To The Main Types And Working Principles Of Blister Packaging Machines

The blister packaging machine is a machine that forms a blister with a transparent plastic film or sheet, and seals the product between the blister and the bottom plate by heat sealing, bonding, etc. Divided from the overall structure and working principle, the blister packaging machines produced in China can generally be divided into two series: roll-type blister packaging machines and flat-type blister packaging machines. The roller-plate blister packaging machine is a high-speed machine, and the flat-plate blister packaging machine is a medium-low speed machine.

The working principle of the roll-type blister packaging machine: the formed film is heated and softened by the heating device, and the blister is sucked out by vacuum negative pressure on the roller-type forming die roller, and the filling device will fill the packaged material into the blister, and then pass through the roller-type The heat sealing device seals the cover film coated with adhesive on one side on the surface of the blister material under appropriate temperature and pressure, and seals the packaged goods in the blister. Then print the batch number and press out the breaking line through the typing and embossing device, and finally the punching device punches it into product plates of a certain size.

The working principle of the flat-plate blister packaging machine: the formed film is heated and softened by the flat-type heating device, and the softened film is blown into a blister by compressed air in the flat-type forming device, and the filling device fills the packaged material into the blister. Then send it to the flat-plate sealing device, seal the cover film and the forming film under appropriate temperature and pressure, then print the batch number and press out the breaking line through the typing and embossing device, and finally cut it into the specified size by the punching device product segment.

The roller-type blister packaging machine is developed on the basis of the roller-type and flat-type blister packaging machines, that is, the flat-type forming device is used for blow molding (positive pressure forming), and the roller-type sealing device is sealed. Its The working principle is basically the same as the above two.
