Thermoforming packaging machine can generally be divided into various models according to the structural layout, the shape and size of the packaged object, and the productivity level. High-speed horizontal thermoforming packaging machine. After the plastic film is radiantly heated by the heater, it can be formed into a blister container on a vacuum roller, so that it can be cooled during the movement. The material is filled after passing several times below the hopper, and then heat-sealed with the aluminum foil at the heat-sealing roller.
Then it moves to the punching position through the tension wheel and bridge wheel to cut, the finished product is output, and the surplus material is rolled up for recycling. The machine's hot but blanking is performed intermittently, so a tensioner is provided.
Stepping type large container thermoforming packaging machine, the general steps are film heating, stretch forming, filling materials, heat sealing, punching and shearing output products, and then recovering the remaining material of packaging materials.
Vertical small thermoforming packaging machine. The general working procedures are thermoforming, filling and heat sealing. The forming rollers and heat sealing rollers roll directly against each other, so there can be a feeding hopper above the two rollers for filling. Therefore, the packaging machine has a compact structure, a small footprint and high production efficiency. This is also the characteristic of vertical packaging machines.
