5.2 After power supply being connected, electrothermal elements start to produce heat, which
leads to rapid temperature rise of both upper and bottom heating blocks. Adjust temperature
controller and speed-regulating mechanism to get the required temperature and speed
respectively. The sealing area of plastic packing bag is conveyed into the clearance between
two sealing belts by conveyor belt first, then clamped by two sealing belts and delivered into
the heating area. The plastic film is heated and fuses. Under the pressure from pinch roller,
the film binds. After this, the sealing area will be conveyed into the cooling area for cooling
and figuration, and then to be pressed by embossing roller for making stripe or netted
pattern.
The running of transmission part of the sealer is started by motor, which drives sealing belts,
guiding belts and conveyor belt through gears to run synchronously.
