Common faults and solutions of liquid packaging machine：
1. Heat sealer body failure of packaging machine does not heat up.
Causes of heat packer failure:
●Packing machine circuit fault;
●Heating pipe failure of packaging machine;
●The fuse of the packing machine is damaged.
Solution to heat packer solution:
●Check the circuit of packing machine, find the fault and maintain the circuit.
●Packaging machine heating tube failure Z simple method is to directly replace the heating tube.
●When the packing machine fuse is damaged, replace the fuse in time.
2. The temperature of the heat sealer of the packaging machine cannot be controlled.
Abnormal temperature of heat packer:
●Packing machine temperature regulator failure;
●Packaging machine thermocouple circuit short circuit.
Solution to abnormal temperature of heat packer:
●When the temperature regulator of the packaging machine fails, it is recommended to replace the temperature regulator.
●When the thermocouple circuit of packaging machine is short, it is recommended to replace the ●thermocouple.The paper feeding motor of the packaging machine cannot work properly.
3. Paper motor failure reasons
●The paper supply control lever of packaging machine is stuck.
●Packing machine start capacitor failure;
●Packaging mechanical and electrical power supply board. Fuse failure;
●The paper supply proximity switch of packaging machine is faulty.
4. Paper motor failure solution：
●When the paper supply control lever of the packaging machine is stuck, see the cause of the stuck and solve it.
●When the starting capacitor of the packaging machine fails, the starting capacitor should be replaced in time.
●When packing machine power plate. When the fuse fails, it is necessary to repair the power board circuit in time and replace the fuse of the packaging machine.
●When the paper supply proximity switch of packaging machine is faulty, please replace the paper supply proximity switch.
5. The bag pulling motor of the packaging machine is faulty：
Reasons for the failure of bag drawing motor:
●Packaging machine control board failure;
●Packing machine circuit fault;
●Packing machine stepper motor driver failure;
●The bag proximity switch of the packaging machine is damaged, or the distance between the sending CAM of the bag is too far.
6. Solution to the fault of bag drawing motor：
●Replace the control board of the packaging machine when it is faulty.
●When the packaging machine circuit failure, should be timely check the packaging machine circuit and maintenance.
●When the stepper motor driver of the packaging machine fails, more stepper motor drivers are needed.
●When the bag proximity switch of the packaging machine is damaged, the bag proximity switch of the packaging machine needs to be replaced. If the distance between the bag-pulling communication cams of the packaging machine is too far, it is necessary to shorten the distance between the bag-pulling communication cams of the packaging machine.
●The packing material is easy to break when the packing machine is operating.
7. Reasons why packaging materials are easy to be broken：
●Paper supply proximity switch failure of packaging machine;
●Irregular packaging materials, burr phenomenon;
●The motor line of paper supply position of packaging machine is faulty.
8. The packing material is easy to be broken：
●When the paper supply proximity switch of the packaging machine is faulty, the paper supply proximity switch of the packaging machine should be replaced.
●When the packaging material is irregular, appear burr phenomenon, need to trim unqualified packaging material.
●When the motor circuit of the paper supply position of the packaging machine fails, the motor circuit of the packaging machine should be checked and repaired in time.
9. The reason for the instability of liquid packaging machine：
●Packing machine cock position installation error;
●Packing machine pipe blockage;
●Packing machine cock rocker position is loose.
