2. After the power supply being connected, the heating element produces heat
that rapidly raise the temperature of both upper and lower heat blocks. By using
the temperature controller and speed-adjusting mechanism, adjust it to the
needed temperature and speed. The plastic packing bag is transmitted by
conveyor belt, and its sealing part will be conveyed into the middle of two
working sealing belts. Then it is clamped by the two sealing belts and conveyed
into the heating area, and sealing part is pressed by two heating blocks and
impressing wheels there, which could make the plastic film fused and stuck
together. After this, the sealing part will be conveyed into the cooling area for
cooling, and then to be pressed by embossing wheel for making stripe or netted
pattern, at last, colored label on the sealing part will be coded by printing wheel.
The sealing and printing transmission are driven by one motor, which drives
sealing belts, guiding belts and conveyor belt to work synchronously, as well as
make printing mechanism working intermittently.
3. Power of vertical sealer makes sealer head run through vertical shaft.
