2. The heating tube of the packaging machine is faulty;
3. The fuse of the packaging machine is damaged.
Solution to failure of heat sealer body:
1. Check the circuit of the packaging machine, find the fault and repair the circuit.
2. If the heating tube of the packaging machine fails, the easiest way is to directly replace the heating tube.
3. When the fuse tube of the packaging machine is damaged, just replace the fuse tube in time.

2. The temperature of the heat sealer body of the packaging machine cannot be controlled

Reasons for abnormal temperature of heat sealer body:
1. The temperature regulator of the packaging machine is malfunctioning;
2. The thermocouple circuit of the packaging machine is short-circuited.
Solution to abnormal temperature of heat sealer body:
1. When the temperature regulator of the packaging machine fails, it is recommended to replace the temperature regulator.
2. When the thermocouple circuit of the packaging machine is short-circuited, it is recommended to replace the thermocouple.

3. The paper feed motor of the packaging machine does not operate normally

Causes of paper feed motor failure:
1. The paper feed lever of the packaging machine is jammed;
2. The starting capacitor of the packaging machine is malfunctioning;
3. The power board and fuse of the packaging machine are malfunctioning;
4. The paper supply proximity switch of the packaging machine is malfunctioning.
Solution to the failure of the paper feed motor:
1. When the paper feed lever of the packaging machine is jammed, look at the cause of the jam and solve it.
2. When the starting capacitor of the packaging machine fails, the starting capacitor needs to be replaced in time.
3. When the power board and fuse of the packaging machine fail, the power board circuit needs to be repaired in time, and the fuse of the packaging machine should be replaced.

4. The bag pulling motor of the packaging machine is malfunctioning

Reasons for the failure of the bag pulling motor:
1. The control panel of the packaging machine is malfunctioning;
2. The line of the packaging machine is malfunctioning;
3. The stepper motor driver of the packaging machine is malfunctioning;
4. The bag pull proximity switch of the packaging machine is damaged, or the distance between the bag pull signal cams of the packaging machine is too far.
Solution to the fault of the bag pulling motor:
1. When the control panel of the packaging machine fails, the control panel of the packaging machine needs to be replaced.
2. When the line of the packaging machine fails, it is necessary to check the line of the packaging machine and repair it in time.
3. When the stepper motor driver of the packaging machine fails, the stepper motor driver of the packaging machine needs to be replaced.
4. When the bag-drawing proximity switch of the packaging machine is damaged, the bag-drawing proximity switch of the packaging machine needs to be replaced; if the distance between the bag-informing cams of the packaging machine is too far, the bag-drawing machine needs to be pulled closer The distance between the signaling cams.

5. Packaging materials are easily broken when the packaging machine is operating

Reasons for the packaging materials to be easily broken:
1. The paper supply proximity switch of the packaging machine fails;
2. Irregular packaging materials and burrs;
3. The motor circuit at the paper feeding position of the packaging machine is faulty.
The packaging material is easy to be broken. Solution:
1. When the paper supply proximity switch of the packaging machine fails, the paper supply proximity switch of the packaging machine needs to be replaced.
2. When the packaging materials are irregular and have burrs, the unqualified packaging materials need to be trimmed.
3. When the motor circuit of the paper feeding position of the packaging machine fails, it is necessary to check and repair the paper feeding motor circuit of the packaging machine in time.

6. Unstable feeding of liquid packaging machine

Reasons for unstable feeding of liquid packaging machine:
1. The position of the cock of the packaging machine is installed incorrectly;
2. The packaging machine pipeline is blocked;
3. The position of the cock and rocker of the packaging machine is loose.
Solution to unstable feeding of liquid packaging machine:
1. When the cock position of the packaging machine is installed incorrectly, the cock position of the packaging machine needs to be adjusted correctly.
2. When the packaging machine pipeline is blocked, it is necessary to unblock the packaging machine pipeline in time to ensure that the pipeline is unblocked.
3. When the position of the cock rocker of the packaging machine is loose, it is necessary to tighten the screws around the cock rocker of the packaging machine.

7. The packaging machine is not tightly sealed

Reasons for improper sealing:
1. The sealing temperature of the packaging machine is lower than normal;
2. The material of the packaging machine is unevenly distributed and irregular;
3. The pressure at the sealing part of the packaging machine is uneven.
Solutions for not tight sealing:
1. When the sealing temperature of the packaging machine is lower than the normal temperature, it is necessary to increase the sealing temperature of the packaging machine.
2. When the material of the packaging machine is unevenly distributed and the material is irregular, the irregular packaging material needs to be trimmed.
3. When the pressure at the sealing part of the packaging machine is not uniform, the sealing pressure value of the packaging machine needs to be adjusted.

8. The sealing of the packaging machine is not correct

Reasons for incorrect sealing:
The position of the heat sealer body of the packaging machine is set incorrectly.
Improper sealing solution:
When the position of the heat-sealing body of the packaging machine is set incorrectly, the position of the heat-sealing body of the packaging machine needs to be adjusted.

9. The filling motor of the packaging machine cannot be started

Reasons for filling motor failure:
1. The drive of the packaging machine is damaged;
2. The filling motor of the packaging machine is malfunctioning;
3. The control board of the packaging machine is malfunctioning;
4. The position of the filling proximity switch of the packaging machine is adjusted incorrectly.
Solution of filling motor fault:
1. When the driver of the packaging machine is damaged, the driver needs to be replaced.
2. When the filling motor of the packaging machine fails, the filling motor needs to be replaced.
3. When the control board of the packaging machine fails, the control board needs to be replaced.
4. When the position of the filling proximity switch of the packaging machine is adjusted incorrectly, the position of the filling proximity switch needs to be adjusted.

10. There is a problem with the color label positioning of the packaging machine

Reasons for color mark positioning failure:
1. The rollers of the packaging machine are frequently used to be ground and the power assist becomes smaller;
2. The bag length setting value of the packaging machine is not accurate;
Color mark positioning fault solution:
1. When the rollers of the packaging machine are frequently used and are ground and the booster becomes small, the rollers need to be replaced.
2. When the bag length setting value of the packaging machine is inaccurate, it is necessary to set an accurate bag length setting value.
