Solutions for Addressing the Burst Line Issue of Corrugated Boxes in Autumn and Winter Using Folder Gluers

As autumn transitions into winter, the drop in temperature and relative humidity leads to an increase in the incidence of paper breakage or bursting in corrugated board. This burst line issue presents significant challenges for the packaging industry. As a key piece of equipment in box forming, the folder gluer can effectively address these problems through the following solutions:

### 1. Precise Humidity Control System

1. **Intelligent Humidity Sensors**: Install high-precision humidity sensors at the feed end of the folder gluer to monitor the moisture content of the paper in real time. When the paper is detected to be too dry, approaching the risk threshold for bursting, an automatic humidification program is triggered.

2. **Diverse Humidification Methods**: Utilize an array of atomizing nozzles to evenly spray fine mist onto the surface of the paper. Additionally, incorporate steam humidification channels for rapid and deep humidification of severely dry paper, ensuring that the moisture content is elevated to a safe range in a short time, effectively preventing bursting.

### 2. Temperature Adaptive Regulation Module

1. **Dynamic Temperature Monitoring**: Set multiple temperature probes in the heating and bonding areas of the folder gluer to accurately track temperature changes in the paper during processing.

2. **Intelligent Temperature Control Algorithm**: Based on the material, thickness of the paper, and environmental temperature, an internal intelligent algorithm automatically adjusts the power of the heating elements. In colder environments, the heating temperature is appropriately lowered to prevent excessive heat from causing rapid moisture loss, which could lead to bursting. During the rapid passage of paper through the folder gluer, precise control of the bonding temperature ensures that the adhesive cures quickly without compromising the paper's flexibility.

### 3. Adhesive Optimization Formulation and Coating Process

1. **Flexible Adhesive Formulation**: Develop a specialized adhesive suitable for autumn and winter, incorporating unique moisturizing agents and flexibility enhancers. The moisturizing agent locks in moisture within the paper, while the flexibility enhancer improves the paper's resistance to folding in low-temperature, dry environments, effectively reducing the risk of bursting.

2. **Precise Coating Technology**: The adhesive coating system can accurately control the amount and location of adhesive applied based on the characteristics and requirements of the paper. This ensures a strong bond for the boxes while avoiding excessive adhesive that could harden the paper and lead to bursting, achieving optimized adhesive application.

These strategies can significantly mitigate the burst line issues faced by corrugated boxes during the autumn and winter months, enhancing the reliability and quality of packaging in these challenging conditions.
