characteristics of high definition, instant print and instant dry and strong adhesion; For letters
in R type arrange, the machine can print two lines in font size two (18PT) and three lines in
font size five (10.5PT), and 20 types can be arranged in each line. Special order for T arrange
or multi-line types is available.
V.Structure & Working principle
1.This machine is made up of rack, speed-adjusting mechanism, sealing temperature
control system, transmission and conveying system, and printing assembly etc..(see
diagram 1~diagram 8)
2.After the power supply being connected, electrothermal elements produce heat that
rapidly raise the temperature of both upper and lower heat blocks. And use the
temperature controller and speed-adjusting mechanism to adjust the temperature that
needed, 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 belt and conveyed into the heating area, sealing part is pressed by two heating
blocks and impressing wheels there, which could make the plastic film fuse and stick
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.
3.The transmission of sealing and printing is started by motor, which drives sealing belts,
guiding belts and conveyor belt to work synchronously, as well as make printing

4
mechanism work intermittently.
4.Power of vertical sealer makes sealer head run through vertical shaft.

12). Temperature adjustment for printing wheel and ink roller:
All the knobs of this machine are set to 0 position before leaving factory. Users need to
make adjustment by themselves. For a new ink roller, during previous time of use, the
temperature should be relatively lower, after a period time of use, the temperature can be
raised to higher degree, which can make the deep-seated ink ooze and prolong the ink
roller’s life-span. When the ink roller reaches the working temperature, use a piece of
white paper to touch ink surface, as long as it can stick a little ink, it should be ok. The
temperature can’t be too high or too low.
The ink roller that suits for this machine specified in following table, including colors of
white, yellow, red, blue, green, brown and black. If the packing bag needs steam cooking
after printing，you should choose the ink rollers of moderate temperature or high
temperature, in this situation, the temperature must be set in higher degree accordingly
while using.
