The automatic gluing line for packaging boxes is a core automation equipment in the packaging industry that improves the efficiency of paper box forming, ensures gluing accuracy, and reduces labor costs. It is suitable for various packaging box mass production needs and covers the production of all types of packaging boxes. The core application value is reflected in four dimensions: "adaptation scenarios, core application advantages, segmented category landing, and industry adaptation". The structured summary is as follows:
1、 Core application scenario: covering key links in the entire production process of packaging boxes
The automatic gluing line is not just a single gluing process, but a core process that connects packaging boxes before forming, adapting to the entire production chain of mass-produced paper boxes and replacing the inefficient mode of manual gluing and semi-automatic gluing
Pre gluing process for box blanks (core application): After the paper box is die cut and formed, the correct gluing is applied to the bonding positions of the box edge, bottom, and cover to prepare for subsequent folding and forming. It is a key pre process for packaging box forming and is suitable for unified gluing of large quantities of box blanks.
Online linkage molding process: It can be linked with paper box folding machine, molding machine, and laminating machine to achieve integrated operation of "gluing → folding → laminating → shaping", without manual transfer, fully automated flow, and suitable for high-speed mass production.
Correct gluing process for irregular packaging boxes: For the irregular adhesive positions of irregular packaging boxes (such as the top and bottom lid and corners of irregular gift boxes), fixed-point gluing is achieved through correct positioning, solving the problem of uneven and leaking glue during manual gluing.
After laminating/mounting paper, apply adhesive: After laminating and mounting the packaging box surface paper (surface paper+corrugated paper/grey cardboard), apply adhesive to the bonding area to ensure a firm fit between the surface paper and the box body, avoiding glue peeling.
2、 Core application value: Compared to manual labor, solving the core pain points of packaging production
This is the core reason for the popularity of automatic glue coating lines in the packaging industry, which is suitable for the needs of mass production and high-quality packaging boxes. The core values are reflected in "efficiency, correctness, cost reduction, and stability"
Improve production efficiency and adapt to large-scale production:
The gluing speed can reach 100-500pcs/minute (adjusted according to the box type), which is 10-20 times more efficient than manual gluing. It is suitable for large-scale orders of essential categories such as e-commerce packaging boxes and food packaging boxes;
Support 24-hour continuous operation without manual fatigue error, able to quickly respond to peak season order demands and shorten delivery cycles.
Ensure adhesive accuracy and improve packaging box quality:
The amount of glue applied is correct and controllable (glue error ≤ 0.02g), the glue line is uniform and straight, without any glue leakage, overflow, or excess glue problems, to avoid glue leakage and contamination of the box surface after bonding, and glue leakage leading to glue failure;
The glue application position is correct (positioning error ≤ 0.1mm), the alignment of the bonding position is high, and the edges and corners of the packaging box are flat and free of warping after molding, which improves the qualification rate of the finished product (from 75% manually to over 99%).
Reduce overall costs and adapt to the demand for mass production cost reduction:
Labor cost: One automatic glue coating line can replace 5-10 glue coating workers, significantly reducing labor wages and management costs for long-term use, especially suitable for the industry trend of rising labor costs;
Glue cost: Properly controlling glue to avoid glue waste, reducing glue loss by 30% to 50% compared to manual glue application, and saving consumable costs;
Rework cost: High yield of finished products, reducing rework and scrap caused by adhesive problems, and lowering loss costs.
Adapt to diverse box types and have strong adaptability for flexible production:
By adjusting parameters such as glue position, glue amount, and speed, it is possible to adapt packaging boxes of different sizes and specifications without the need for significant mold changes. Switching box types only takes 5-10 minutes;
Supporting various adhesives such as water-based adhesive, hot melt adhesive, and oil-based adhesive, adapting to the bonding needs of different material packaging boxes, and flexibly adapting to multiple category orders.
Improve production stability and adapt to standardized production:
Fully automated operation, not affected by manual proficiency or emotions, with uniform and stable glue application effect, ensuring consistent quality of packaging boxes in the same batch, and adapting to the standardized packaging needs of enterprises;
Equipped with leak proof glue and broken glue alarm function, it can promptly troubleshoot and avoid the production of batches of defective products.
