Flat bag making machines can be said to achieve fully automated operation, requiring only 1-2 people to operate the equipment. The flat bag making machine can adjust the production speed and product size, and is equipped with not only fixed length but also photoelectric tracking, ensuring accurate and stable operation. Therefore, the use of flat bag making machines reduces labor intensity and improves work efficiency to a certain extent. During the bag making process, due to operation and maintenance reasons, some problems may occur in the finished products, such as spots and small holes.

I. Spots on the bag

1. The glue roller and aluminum roller are not wiped clean;

2. The bottom of the front and rear pressure plates is not wiped clean;

3. There is dirt on the conveyor belt;

Solution:

1. Wipe all parts clean with a cleaning cloth;

2. Clean the bottom of the pressure plate with a printing solvent;

3. Polish with a polishing machine and then clean;

4. Wipe the cutting edge with a wet cloth strip, check if the temperature is normal, and adjust to the appropriate temperature if not.

II. Small holes on the bag

1. Burnt material on the cutting edge;

2. The pressure plate is not pressed well;

3. The speed is too fast;

4. The zipper or gusset is too thick;

5. The discharge roller is damaged.

Solution:

1. Wipe the cutting edge clean and lower the temperature by 5-10 degrees Celsius;

2. Re-press the pressure plate;

3. Adjust the speed;

4. Make the zipper or gusset thinner;

5. Replace the discharge roller.
