Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a high-efficiency laminating device for producing corrugated paper boxes. Background Art

[0002] Corrugated boxes are a commonly used packaging material, constructed from multiple layers of cardboard, with a corrugated core sandwiched between two or more layers of flat cardboard. This structure gives the box excellent strength, cushioning properties, and stiffness, effectively protecting the contents from damage such as collisions and squeezing during transportation and storage. Corrugated boxes are also low-cost, lightweight, and recyclable, making them widely used in logistics and commerce. High-efficiency laminating devices are used in corrugated box production because they significantly improve production efficiency. Traditional laminating methods can suffer from loose or uneven lamination, impacting box quality. However, high-efficiency laminating devices can accurately and quickly assemble the layers of cardboard tightly, ensuring the structural stability of the corrugated box and thus improving product qualification rates. Furthermore, they can complete more laminating tasks per unit time, meeting the needs of large-scale production, reducing production costs, and enhancing companies' market competitiveness.

[0003] When using the high-efficiency laminating device for traditional corrugated cardboard production, first inspect and debug the device and prepare materials, including checking component installation, circuit, gas and oil line connections, adjusting pressure and temperature parameters according to carton parameters, cleaning and cutting cardboard, and preparing glue; if there is a mold, install and debug the mold, preheat the machine with heating function and check the temperature control system and transmission components, then place the cardboard on the conveyor belt, start the operation through the control device, and use rollers, pressure plates and other components to complete the lamination according to the set parameters. Continuously monitor the operating status during production and deal with problems in a timely manner.

[0004] The traditional high-efficiency bonding device for the production of corrugated cardboard has gaps between the cardboards, and the glue is easily unevenly applied, which will lead to a decrease in the overall structural strength. The uneven glue application will make the adhesion between the cardboards not firm. During the use of the carton, delamination and degumming will occur. When the carton is subjected to a certain pulling or tearing force, the areas with less glue are easily separated, thereby destroying the integrity of the carton and the glue is unevenly applied.
