Xusen's first-of-its-kind, independently-protected intellectual property-based intelligent electromagnetic speed-up system for the double-sided machine of the corrugated cardboard production line has broken through the limitations of traditional processes, which cannot meet the requirements of modern high-speed production lines.
1. Advanced algorithms enable continuous and stable high-speed production of the paper line:
The traditional method of speeding up the double-sided machine of the paper line involves using a crease tip accelerator to heat the upper layer of the paper crease with steam. The steam used is mainly the saturated original steam from the boiler, with a spray temperature ranging from 120°C to 135°C (0.2-0.3 MPa), and the surface temperature of the crease tip reaches 90°C to 110°C. Moreover, due to the oversized design of the traditional crease tip accelerator, the installation distance from the heat plate inlet is far, and during the high-speed operation of the paper line, the temperature of the crease tip cannot meet the process requirements. It also increases the moisture content of the upper layer, requiring more steam energy consumption, resulting in an imbalance of moisture in each paper layer, and causing the paper board to warp after re-humidification.
The Xushen electromagnetic speed-up system, relying on advanced algorithms, when the paper line reaches the set speed, the system intelligently intervenes based on current production order materials, speed, gate width, and paper surface temperature data. It quickly introduces hot low-pressure condensed water into the steam, with a spray temperature ranging from 120°C to 480°C. Combined with Xushen's unique structural design, it is closer to the upper layer crease tip, ensuring a higher temperature of the corrugated crease tip. Through the high-speed movement of the upper layer corrugated paper, the high-temperature steam is brought into the heat plate to ensure that the glue of the upper layer crease tip reaches the required temperature and humidity for starch expansion, penetration, gelation, and curing. Even when the paper line operates at a speed exceeding 350 meters per minute, it can still ensure good adhesion of the upper layer of the paper board.
2. Intelligent control significantly improves the quality of paperboard:
The traditional method of accelerating the crests uses the spraying of saturated steam, which contains a high moisture content. During high-speed production, it is difficult to ensure that the upper paperboard crests reach the required temperature. To ensure the quality of the paperboard, the common operation method is to increase the glue application amount and reduce the production speed. Due to the high moisture content of the upper paperboard crests, the moisture content of each paper layer is uneven, which easily leads to quality problems such as warping, false adhesion, and poor crease shape of the paperboard.
The Xushen electromagnetic speed-up system re-heats the condensate water discharged from the production line to generate low-pressure superheated steam, with temperature control possible. The electromagnetic superheated steam has a high temperature and extremely low moisture content. Combined with a more reasonable crease accelerator structure design, the upper paperboard crests enter the hot plate at a higher temperature, significantly reducing the temperature of the hot plate and the amount of glue application, and reducing the consumption of starch. Reducing the amount of glue application can also reduce the steam consumption in the hot plate area. While ensuring good adhesion of the paperboard, it also improves the physical indicators of the paperboard, such as compressive strength, burst resistance, and flatness.
3. Unique Design Continuously Creates Value for Customers:
Compared with the traditional method that requires 2-3 kilograms of steam pressure, the Xushen intelligent speed-up system utilizes the condensate water discharged from the production line to generate steam. It only requires 0.5-0.8 kilograms of steam pressure to ensure the high-speed and stable operation of the paper line.
Based on a 2.5-meter paperboard production line with a daily output of 500,000 square meters of paperboard, it can save 3-5 tons of steam energy consumption per day.
Based on a 2.5-meter paperboard production line with an average speed increase of 20 meters per minute per month, it can increase production capacity by 1.5 million square meters per month, save three days of production time, and save more than 120 tons of steam and other costs such as labor, electricity, and other expenses.
