Folder Gluer Troubleshooting
automatic folder gluing machine
The box gluing machine may encounter various faults during use, affecting production efficiency and product quality. The following are common box gluing machine faults and their troubleshooting methods:
- The paper box is not firmly bonded
Possible reasons:
The glue concentration is not appropriate.
Insufficient glue or uneven glue application.
Insufficient pressing force.
The cardboard material is not suitable.
Solution:
Adjust the glue concentration to ensure the glue quality.
Check the gluing system and clean the blocked glue nozzle.
Increase the pressing force or extend the pressing time.
Replace the appropriate cardboard material.
- The paper box is not folded accurately
Possible reasons:
The cardboard size is not standard.
The folding device is not adjusted properly.
The conveyor belt speed does not match.
The cardboard is deformed or damp.
Solution:
Check whether the cardboard size meets the requirements.
Re-adjust the position and angle of the folding device.
Adjust the conveyor belt speed to ensure synchronization with the folding device.
Replace dry and flat cardboard.
- Conveyor belt jam
Possible causes:
Uneven cardboard thickness.
Foreign objects on the conveyor belt.
Insufficient or too tight conveyor belt tension.
Too many burrs on the cardboard edge.
Solution:
Check the cardboard thickness to ensure consistency.
Clean foreign objects on the conveyor belt.
Adjust the conveyor belt tension to the appropriate state.
Trim the cardboard edge to remove burrs.
- Uneven glue coating or glue leakage
Possible causes:
The glue nozzle is blocked.
Insufficient glue supply.
The glue wheel is worn or dirty.
The glue pressure is unstable.
Solution:
Clean the glue nozzle to ensure smooth flow.
Check the glue supply system and add glue.
Clean or replace the glue wheel.
Adjust the glue pressure to ensure stability.
- The machine is running too noisy
Possible causes:
Insufficient lubrication of mechanical parts.
Loose screws or worn parts.
Motor or transmission system failure.
Solution:
Regularly lubricate mechanical parts.
Check and tighten loose screws and replace worn parts.
Check the motor and transmission system, and repair or replace if necessary.
- The folder gluer cannot start
Possible causes:
Power failure.
The emergency stop button is pressed.
Control system failure.
Motor or drive damaged.
Solution:
Check whether the power connection is normal.
Check whether the emergency stop button is reset.
Restart the control system or contact a technician for repair.
Check the motor and drive, and replace if necessary.
- The paper box is deformed after pressing
Possible causes:
Pressing force is too large.
The cardboard material is too thin or of poor quality.
Pressing time is too long.
Solution:
Adjust the pressing force to the appropriate state.
Replace high-quality cardboard material.
Shorten the pressing time.
- The speed of the folder gluer slows down
Possible reasons:
Insufficient motor power.
Excessive resistance in the transmission system.
Improper setting of control system parameters.
Solution:
Check whether the motor power matches.
Clean the transmission system to reduce resistance.
Adjust control system parameters to optimize running speed.
- Glue overflow or waste
Possible reasons:
Excessive glue supply.
Excessive speed of the glue coating wheel.
Failure of the glue recovery system.
Solution:
Adjust the glue supply.
Reduce the speed of the glue coating wheel.
Check and repair the glue recovery system.
- Control system failure
Possible reasons:
Program error or improper parameter setting.
Sensor failure.
Controller hardware damage.
Solution:
Reset program parameters.
Check and replace the faulty sensor.
Contact the manufacturer for repair or replacement of the controller.
Daily maintenance suggestions:
Clean the machine regularly, especially the gluing system and conveyor belt.
Check the wear of mechanical parts regularly and replace them in time.
Keep the glue system clean to prevent blockage.
Lubricate moving parts regularly to reduce friction and noise.
Train operators, standardize operating procedures, and avoid human errors.
Through the above methods, common faults of the folder gluer can be effectively eliminated, ensuring stable operation of the equipment and improving production efficiency. If the problem is complicated, it is recommended to contact professional technicians or manufacturer support.
