As an important equipment in modern packaging production lines, fully automatic horizontal box packing machines are inevitably prone to various malfunctions during long-term operation. The following are common types of faults and their corresponding solutions:
1、 Suction box system malfunction
1. The suction box is not in place or there is no in-situ detection of the suction box
(1) Check if the cylinder is working properly and ensure that it has sufficient thrust and stability.
(2) Check if the throttle valve is adjusted properly and adjust it to optimize airflow control.
(3) Check if there is a problem with the delay valve and replace or repair it if necessary.
(4) Clean foreign objects in the air system to ensure unobstructed air flow.
(5) If the suction box is detected to be abnormal, check the photoelectric switch and corresponding circuit to ensure its normal operation.
2. The suction cup is damaged, causing the suction box to be unable to hold it
(1) Replace the suction cup with a new one, ensuring that the surface of the suction cup is flat and undamaged.
(2) Check whether the vacuum generator and pipeline are working properly, and repair or replace them if necessary.
(3) Check if the air path is unobstructed and clean any possible blockages.
(4) If the air path is unobstructed and unobstructed, check whether the rubber sealing ring on the suction cup seat is damaged or detached, and replace it with a new sealing ring in a timely manner.
(5) Clean the dirt on the suction cup and keep its surface clean.
2、 Paper box transport and jamming fault
1. Paper box jamming causes abnormal packaging
(1) Check the stuck position of the cardboard box and make corresponding adjustments and optimizations.
(2) Check if the motor of the box feeding conveyor belt is working properly, and replace the motor in a timely manner if there is a malfunction.
(3) Check whether the baffles at both ends of the box conveyor belt are installed correctly, and reinstall them if necessary to ensure their accurate position.
(4) Adjust the speed of the box feeding conveyor belt to match the speed of the box packing machine to avoid jamming caused by inconsistent speeds.
2. The cardboard box has no separation action or cannot be opened after separation
(1) Check whether the cardboard box is damaged or deformed, and replace the unqualified cardboard box in a timely manner.
(2) Check if the strength of the push rod is sufficient and replace it with a stronger one if necessary.
(3) Adjust the air pressure to the normal range, ensuring that the air pressure is stable and sufficient.
(4) Check if the solenoid valve and corresponding circuit are working properly. If there is a malfunction, replace the solenoid valve or repair the circuit in a timely manner.
3、 Abnormal equipment operation and malfunction
1. The conveyor belt stops or occasionally pauses
(1) Cut off the power supply, check if the power supply is normal and if the speed regulator and motor are working properly.
(2) If it is occasional shutdown, supplement the automatic startup steps and check if the equipment is missing materials.
(3) Regularly inspect and maintain key components such as power supply, motor, and speed controller to ensure their stable operation.
2. The instruction manual cannot be suctioned smoothly
(1) Check if the suction head is at the same horizontal position as the outlet in the instruction manual and adjust it to the correct position.
(2) Check if the surface of the instruction manual is flat, as uneven instructions can affect the suction of the suction head.
(3) Check if the timing of the paper separator operation is correct. The separator should be inserted into the middle of the paper before the suction head descends for separation.
(4) Adjust the operation time of the paper separator to ensure separation is carried out at the correct time.
4、 Preventive measures for faults
1. Strict operating procedures: Operate according to the equipment manual specifications to avoid human errors that may cause malfunctions.
2. Regular maintenance: Establish an equipment maintenance plan and regularly inspect key components such as cylinders, suction cups, conveyor belts, etc.
3. Keep the equipment clean: Regularly clean the inside and outside of the equipment to prevent dust and foreign objects from affecting its operation.
4. Maintenance of pneumatic system: Regularly check the pneumatic system to ensure smooth and stable air pressure.
5. Electrical system inspection: Regularly check electrical circuits and sensors to ensure normal signal transmission.
Through the above fault handling methods and preventive measures, the occurrence rate of faults in fully automatic horizontal box packing machines can be effectively reduced, and the operational efficiency and stability of the equipment can be improved. For complex faults, it is recommended to contact professional maintenance personnel for repair.
