Common faults of bag making machines include

1. Cutting knife not working: Cutting knife motor failure or power line issue; Cutting knife stuck or blade worn; Failure of the cutting knife drive mechanism.
2. Machine overheating: Heat sealing component failure or overload; Cooling system not working or ineffective.
3. Excessive noise: Check if machine parts are loose, and readjust and tighten the relevant components.
4. Insecure bag sealing: Adjust the temperature and pressure of the sealing device to ensure a secure seal.
5. Feeding not smooth: Feeding roller or feeding system failure; Material roll not aligned or uneven tension; Material quality issues, such as uneven thickness or misaligned rolls.
6. Machine running unstable: Transmission system issues, such as loose belts; Wear or damage of machine parts.
7. Bag making machine stops: Sensor failure or false triggering; Control system failure.
8. Low production efficiency of the bag making machine: Improper equipment maintenance; Equipment aging or wear.
9. Inflexible cylinder phenomenon in bag making machine: Check if the cylinder is well-lubricated, and adjust the working pressure of the cylinder. 10. Electrical faults in bag making machine: Check if the circuit connections are good, verify if the electrical components are working properly, and replace damaged electrical components in a timely manner.
