Sealing belt is
off-tracking.
Driving wheel shaft is not parallel to driven
wheel shaft.
Adjust two adjusting screws on driven
wheel seat.
Sealing belt is easy to
broke.
1.Too much tension on sealing belt.
2. Sealing belt is off tracking.
3. Crease on sealing belt.
4. Adhesive film or other dirt attached to
sealing belt surface.
5. Sealing belt is easy to burn.

on driven wheel seat, so as to make
sealing belt less loose
2.

.
3. No crease on sealing belt.
4. Clean its surface in time
5. Clearance between two heating
blocks is too small or temperature is
too high.
Embossing is not clear. 1. Embossing wheel is worn out.
2. Pressing spring on embossing wheel is not
tightened to enough degree.

so that not only ensure the strong
sealing and clear printing, but not
make the two ends of sealing part
extend too long.
There is block or fold
phenomenon when the
packing bag is conveyed
to middle pressing wheel
or embossing wheel.
Too much pressure caused by pressing

、
Adjust the pressing wheel or
embossing wheel to proper pressure,
so as to make the clearance between
two sealing belts be about thickness of
packing bag in one layer. So that not
only ensure the strong sealing and
clear printing, but not make the two
ends of sealing part extend too long.
2. Adjust limiting screw after adjusting
clearance.
Conveyor belt is
off-tracking.
The driving roller shaft is not parallel to driven
roller shaft.
Adjust two adjusting screws of driven
roller shaft (rear shaft) on conveyor
table.
Conveyor belt and sealing
belt
don’t move
