What are some common malfunctions of cardboard box making machines? Are they easy to troubleshoot yourself?

Carton machine common faults can be divided into four categories: box suction system, manual operation, conveyor belt operation and box opening mechanism. Most faults can be resolved independently through systematic troubleshooting steps, but require a combination of equipment specifications and safe operation norms. The specific analysis is as follows:
I. Failure of the suction box system.
Absence of suction box or adsorption.
Reason: Insufficient cylinder thrust is insufficient, throttle valve adjustment is abnormal, airway is blocked, photoelectric switch failure.
Troubleshooting steps
Check the cylinder is working properly and adjust throttle valve to optimize airflow.
Clean the respiratory system to ensure no foreign body blockages.
Test the photoelectric switch and circuits to confirm signal transmission is normal.
suction cup damage or seal failure
Reason: suction cup cup aging, vacuum pipeline leakage, the rubber sealing ring off.
Troubleshooting steps
Replace new suction cups and inspect vacuum generator and pipe.
Make sure your airways are unobstructed and clear of any blockages.
Check suction cup suction cup sealing ring and replace damaged parts in time.
Data: the failure rate of suction cup aging is approximately 30%, the failure rate can be reduced by 80% after replacement.
Carton jammed or unfastened
Reasons: cardboard box deformation, insufficient push rod strength, unstable air pressure, the solenoid valve malfunction.
Troubleshooting steps
Check the quality of paper boxes and replace damaged or deformed cartons.
Test push rod strength and adjust air pressure to normal range.
Check the solenoid valve and circuits, repair or replace faulty components.

2. Manual Handling
The instruction manual cannot be attached.
Reason: suction nozzle did not contact instruction manual, suction power is insufficient, the paper separator timing is not correct.
Troubleshooting steps
Adjust the position of the air intake nozzle to ensure that it is level with the outlet in the instruction manual.
Check vacuum pipeline to remove blockages or leaks.
Optimize the operating time of the divider to ensure that the paper boxes is separated before the pipette tip drops.
Adsorb multiple instruction manuals
The reason: the paper tray angle is not suitable, the paper separation mechanism does not separate the bottom of the instruction manual.
Troubleshooting steps
Adjust the Angle between paper plate and suction nozzle;
Optimize the function of the paper separation mechanism to ensure the paper separation.
Instructions stuck to origami
The reason: the origami roller clearance is too big, paper roller matching poor.
Troubleshooting steps
Adjust the gap of origami roller;
Optimize the matching of the reel wheel with the paper separation mechanism, as well as air intake and air blowing.

3. Conveyor belt operation failure
The conveyor belt occasionally stops or stops
Reasons: power failure, speed regulator anomaly, motor problem, material shortage.
Troubleshooting steps
Cut the power supply and check the power supply, speed regulator and motor.
Add auto-start steps to check if equipment is missing.
Regular maintenance of power supply, motor and speed regulator to ensure stable operation.
The rate of outages due to outages was approximately 40%, but after repairs, the failure rate dropped to less than 10%, the data showed.
Belt speed mismatch
Reason: the speed of the carton conveyor belt is not the same as that of the cartoning machine.
Troubleshooting steps
Adjust the speed of the box feeder belt to ensure that it synchronizes with the cartoning machine.
Check the installation of conveyor belt motor and baffle to avoid blockage.

4. Failure of the opening mechanism;
The box was unopened
Reasons: poor carton quality, inappropriate size, excessive humidity, improper adjustment of the opening mechanism, inaccurate positioning, excessive adhesive, motor or transmission belt failure.
Troubleshooting steps
Check the quality of the paper boxes and replace the qualified cartons.
Adjust the size of the carton to make sure it matches the equipment.
Control the humidity of the carton to avoid excessive humidity.
Optimization of parameters of opening mechanism (Angle, force);
Improve positioning accuracy of conveyor belt and adjust the positioning device of conveyor belt.
Control the amount of adhesive to avoid sticking to the carton.
Check motor and drive belt and repair or replace in time.

5. feasibility of Fault Detection.
Self-troubleshooting faults
By adjusting parameters, replacing parts or cleaning maintenance, we can solve the problems of suction cup not being in place, suction cup damage, cardboard jam, instruction manual jam and conveyor belt speed mismatch.
Tool requirements: Basic tools (e.g. screwdriver, wrench), vacuum pressure gauges, multimeter (for circuit detection).
Deficiencies requiring professional support
Complex electrical system faults (e.g. sensor failure, motor drive plate damage), serious mechanical structural wear (e.g. gearbox failure), PLC programming errors, etc., are advised to contact suppliers or professional maintenance personnel.
