13. Troubleshooting

Problem

Reason

Solution

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

break.

1. Too much tension on sealing belt.

2. Sealing belt is off tracking.

3. Crease on sealing belt.

4. Film or other dirt attached to the

surface of sealing belt.

5. Sealing belt is easy to burn.

1. Adjust the vertical adjusting screw

on driven wheel seat to decrease

tension on sealing belt.

（

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

low

definition.

1. Embossing roller is worn out.

2. Pressure spring on embossing roller

is not tightened to enough degree.

1. Replace embossing roller

2. Adjust the embossing roller

’s

tightening spring.

There is resistance when

the

sealing

belt

conveying.

The clearance between heating blocks

or cooling blocks is too small, so 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 sealing

fastness, high-definition embossing,

but not make the two ends of sealing

area extend too long.

There is block or folding

phenomenon when the

packing bag is conveyed

pinch

roller

embossing roller.

Too much pressure caused by pinch

roller or embossing roller.

1. Adjust proper pressure for the pinch

roller or embossing roller, so as to

make the clearance between two

sealing belts be about thickness of

packing bag in one layer so that not

only

ensure

sealing

fastness,

high-definition embossing, but not

make the two ends of sealing area

extend too long.

2. Adjust limiting screw after adjusting

clearance.

Conveying belt is off

tracking.

The driving roller shaft is not parallel to

driven roller shaft.

Adjust two adjusting screws for driven

roller shaft (rear shaft) on conveyor.

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.
