IX. Troubleshooting
Problem Reason Solution
Fail to work 1. Power supply disconnected
2. Fuse broken or Circuit breaker
tripped
3. Emergency Switch fail to reset after
being Pressed
1. Check the power socket
2. Replace fuse or circuit breaker
3. Reset the Emergency Switch
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.
1. Adjust the vertical adjusting screw on
driven wheel seat, so as to make sealing
belt less loose
2.
（
see the point above

.
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.
1. Replace embossing wheel.
2. Adjust the embossing wheel’s
tightening spring.
There is resistance
when the sealing
belt is conveying.
The clearance between heating blocks or
cooling blocks is too small, the friction is
too much.
Adjust the clearance between sealing belts
properly, which should 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.
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
wheel or embossing wheel.

、
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
synchronously.
Too small tension on conveyor belt.
1. Tighten the chain of driving roller shaft
(front shaft) and middle shaft properly.
2. Tighten the conveyor belt properly
