During the box gluing process, you may encounter some common problems that will affect the quality and production efficiency of the paper box. The following are common problems in the box gluing process and their possible causes and solutions:
- Poor bonding
Performance: The seams of the paper box are prone to cracking or degumming.
Cause:
The glue is of poor quality or expired.
The glue is not applied evenly or in insufficient quantity.
There is oil or dust on the surface of the cardboard, which affects the bonding.
Insufficient pressure causes the glue to not fully penetrate.
Solution:
Check the quality of the glue and choose glue suitable for the cardboard material.
Adjust the amount of glue to ensure uniform coating.
Clean the surface of the cardboard to ensure that there is no oil or dust.
Increase the pressing pressure or extend the pressing time.
- Dimension deviation
Performance: The size of the paper box after forming does not meet the design requirements.
Cause:
The template is designed incorrectly or worn.
The cardboard is not cut accurately.
The box gluing machine is not properly debugged.
Solution:
Check and replace the template.
Ensure the accuracy of cardboard cutting.
Re-adjust the box gluer to ensure that all parts are aligned.
- Unclear creases
Performance: The creases of the box are not obvious, which affects the appearance of the molding.
Cause:
The creasing knife is worn or the pressure is insufficient.
The cardboard material is too hard or too thick.
Solution:
Replace or repair the creasing knife.
Adjust the creasing pressure.
Choose a suitable cardboard material.
- Surface scratches or creasing
Performance: Scratches or creasing appear on the surface of the box.
Cause:
There are foreign objects on the conveyor belt or roller of the box gluer.
The surface coating of the cardboard is not wear-resistant.
Solution:
Clean the conveyor belt and roller of the box gluer.
Choose a cardboard material with better wear resistance.
- Glue overflow
Performance: Glue overflows to the surface of the box, affecting the appearance.
Cause:
Too much glue is applied.
The viscosity of the glue is too low.
Solution:
Adjust the amount of glue applied.
Choose glue with higher viscosity.
- Uneven carton forming
Performance: The carton is skewed or asymmetrical after forming.
Cause:
Uneven cardboard cutting.
Inaccurate positioning of the box gluer.
Solution:
Check the quality of cardboard cutting.
Re-adjust the positioning device of the box gluer.
- Low production efficiency
Performance: Slow box gluing speed affects overall production efficiency.
Cause:
Aging equipment or insufficient maintenance.
Unskilled operators.
Solution:
Maintain equipment regularly and replace wearing parts.
Train operators to improve operational proficiency.
- Insufficient carton strength
Performance: Poor load-bearing capacity of carton and easy deformation.
Cause:
The cardboard material is too thin or of poor quality.
Insufficient glue bonding strength.
Solution:
Choose thicker or higher quality cardboard.
Replace with high-strength glue.
- Bubbles on the surface of the paper box
Performance: Bubbles or unevenness on the surface of the paper box.
Cause:
Uneven glue coating.
The cardboard is damp or uneven in quality.
Solution:
Adjust the glue coating device to ensure uniform coating.
Check the quality of the cardboard and avoid using damp materials.
- Equipment failure
Performance: The box gluing machine is unstable or shut down.
Cause:
Wear or damage of equipment parts.
Unstable power supply or air pressure.
Solution:
Check the equipment regularly and replace worn parts.
Ensure stable power supply and air pressure supply.
By analyzing these problems and taking corresponding solutions, the quality and production efficiency of box gluing can be effectively improved. At the same time, regular maintenance of equipment and training of operators are also the key to reducing the occurrence of problems.
