The working principle of the blister machine mainly includes the following steps:
1. Heating and softening:
The forming film is heated and softened by the heating device to make it easy to form.
2. Forming:
In the forming device, the softened film is blown into blisters. For roller blister packaging machines, a roller-type forming die roller is used to suck out the blisters through vacuum negative pressure; for flat blister packaging machines, compressed air is used to blow the softened film into blisters.
3. Filling:
The filling device fills the packaged material into the blister.
4. Sealing:
Under appropriate temperature and pressure, the cover film and the bottom film are sealed by the heat sealing device to seal the packaged material in the blister.
5. Printing and cutting:
The batch number and the break line are printed by the typing and stamping device, and finally the product block is punched into the specified size by the punching device.
Specific applications and common types of blister machines
Blister machines are widely used in the packaging of medicines, foods and other products. Common types of blister machines include:
1. Roller blister packaging machine: suitable for large-scale production, with roller-type forming die rollers and heat sealing devices to achieve efficient packaging.
2. Flat blister packaging machine: suitable for small-batch production or special-shaped packaging needs, formed by flat heating devices and compressed air.
3. Blister sealing machine: used to seal blisters and paper cards of different materials, using the principle of heat sealing to achieve sealing.
These different types of blister machines have their own advantages, and you can choose the appropriate model for production according to specific needs.
