In the modern packaging industry, corrugated board is widely used for packaging and transportation of various products. Among them, 7-ply corrugated board is favored for its strength and durability. The gluing machine is a crucial part of the seven-layer corrugated board production line. Let's take a closer look at how the gluing machine works and plays a key role in this production line.


The Role and Principle of the Gluing Machine
A gluing machine is a device used to evenly apply adhesive to the flute peaks of corrugated board. The main principle is that the adhesive (usually starch paste) is applied to the surface of the corrugated board through rollers or nozzles, and then the layers of the board are glued together through pressure rollers or platens. This application of adhesive ensures a good bond between the layers of the cardboard, thus enhancing the strength and stability of the cardboard.


The state of the gluing machine in a seven-layer corrugated board production line
Preparation of the adhesive: Before the production line starts, the operator prepares the right amount of adhesive, usually starch paste or other cardboard adhesives. These adhesives are stored in special containers for use in the gluing machine.


Adjustment of equipment parameters: The operator adjusts the parameters of the gluing machine according to the production requirements and board specifications, including application speed, thickness of application, etc. This ensures that the adhesive is applied evenly. This ensures that the adhesive is evenly applied to the board surface.


Continuous operation: Once the gluer is started, it continuously applies the adhesive to the flute peaks of the corrugated board. This process is usually automated, but requires the operator to monitor the machine's operating status and make adjustments and maintenance in a timely manner.


Quality control: Quality control is crucial in the working process of a glue applicator. Operators regularly check the coating to ensure that the adhesive is evenly applied to the cardboard surface to avoid poor bonding or uneven coating.


Maintenance and Cleaning: The gluing machine requires regular maintenance and cleaning after a long period of operation to ensure the stability and performance of the equipment. This includes tasks such as cleaning the gluing rollers and replacing the gluing nozzles.


Conclusion
The gluer plays a key role in the seven-layer corrugated board production line, and its working condition directly affects the quality and productivity of the board. By gaining a deeper understanding of the working principle and status of the gluing machine, we can better understand the entire production process of the corrugated board production line, thus improving production efficiency and product quality.
