In the paperboard industry, productivity and product quality are always at the centre of a company's concerns. Today, we will share our experience in retrofitting a seven-layer corrugated board production line, with a focus on upgrading the gluing machine and preheater. These modifications not only significantly increased production speed, but also saved glue volume, improved preheating speed, and reduced scrap.


Gluing Machine Retrofit: Saving Gum Volume and Increasing Productivity
Modification contents
Precision control system: Introducing advanced precision control system to realise accurate control of gluing volume and reduce waste.
Automatic adjustment function: automatically adjust the gluing volume according to the thickness and material of cardboard, ensuring the consistency and effectiveness of each gluing.
High-efficiency gluing head: Replacing the gluing head with a high-efficiency gluing head improves the gluing speed and ensures the even distribution of glue.
Advantages
Save glue volume: Through precise control, the waste of glue is reduced and production costs are saved.
Increased production speed: The high efficiency gluing head and the automatic adjustment function significantly increase the production speed, making the whole production line much more efficient.
Enhance product quality: Ensure even gluing of each piece of cardboard and reduce the scrap rate caused by uneven gluing.
Preheater modification: Improve preheating speed and reduce scrap rate.
Modification contents
High-efficiency heating system: adopt new type of high-efficiency heating element to improve the preheating speed.
Temperature control system: introduce intelligent temperature control system to ensure the stability and uniformity of preheating temperature.
Optimised heat transfer design: optimise the heat transfer structure of the preheater to improve thermal efficiency.
Modification Advantages
Increased preheating speed: The high efficiency heating system and the optimised heat transfer design have significantly increased the preheating speed and accelerated the overall production pace.
Uniform and stable temperature: Intelligent temperature control system ensures the uniformity of cardboard preheating and reduces quality problems caused by uneven temperature.
Reduced scrap rate: Stable preheating temperature and uniform heat transfer effectively reduce the scrap rate and improve the overall quality of the product.
Overall Advantages after Modification
The overall performance of the seven-layer corrugated board production line has been significantly improved through the renovation of the gluer and preheater:


Increased production speed: The efficient operation of the gluer and preheater has resulted in a significant increase in the overall speed of the production line and an increase in production efficiency.
Reduced costs: The savings in glue volume and reduced scrap rate have effectively reduced production costs and improved economic efficiency.
Product Quality Improvement: More uniform glue application and stable preheating temperature ensure high quality of each batch to meet market demand.
Conclusion
Retrofitting the gluing machine and preheater of the seven-layer corrugated board production line has not only brought about an increase in production efficiency and a reduction in costs, but has also significantly improved product quality. These modifications have undoubtedly won the company more advantages in the fierce market competition. If you are also looking for ways to improve the performance of your production line, you may want to consider starting with the upgrading of these key equipment.
