Ⅰ. 4000/350 Meters Left Paper Machine (Multi-Cylinder Fourdrinier Paper Machine)
This left-positioned multi-cylinder fourdrinier paper machine, with a specification of 4000/350 meters, comes fully equipped with the following key components to ensure stable and efficient paper production:
- High-speed bottom thread rewinder, manufactured by Changshu High-tech, designed for precise and rapid winding of finished paper rolls to meet high-speed production demands.
- Horizontal paper winding machine, which includes 8 paper winding rollers for consistent tension control during winding, plus a scanner to monitor paper quality in real-time and detect defects promptly.
- Drying part with dimensions of 1800×4400×5100 mm, featuring 36 groups of cylinders. It adopts a closed gearbox transmission system, ensuring smooth power transfer, low noise, and reliable operation for effective moisture removal from the paper web.
- Guide roller with specifications of 300×4500×5100 mm, supported by a pig iron frame. The sturdy pig iron structure provides strong stability, preventing roller deformation and ensuring accurate guiding of the paper web during the production process.
- Sizing machine with a roller diameter of 900 mm, used to apply a uniform size coating on the paper surface, enhancing paper properties such as water resistance, smoothness, and strength.
- Pressing section equipped with two blind hole presses, each with a diameter of 1100 mm. These presses effectively squeeze out excess water from the wet paper web, improving paper dryness and reducing subsequent drying energy consumption.
- Wire section integrated with an air cushion type headbox for uniform distribution of pulp onto the wire. The wire has a length of 20 meters, and the dehydration system includes an original stainless steel box (resistant to corrosion and easy to clean) and a ceramic panel (wear-resistant to ensure long service life). The entire frame is covered with stainless steel for enhanced durability and hygiene. Additionally, it is equipped with a vacuum couch roll measuring 900×4600×5300 mm, which aids in initial dehydration and stable transfer of the wet paper web from the wire to the pressing section.
Ⅱ. 3600/300 Meters Right Paper Machine (Multi-Cylinder High-Strength Corrugated Paper Machine)
This right-positioned multi-cylinder paper machine, specified as 3600/300 meters, is specialized in producing high-strength corrugated paper, with its core components detailed as follows:
- A set of ordinary frame rewinding machine, designed to wind the produced high-strength corrugated paper into neat rolls. The ordinary frame structure ensures simplicity in operation and maintenance, suitable for stable production scenarios.
- One horizontal winder, which works in coordination with the rewinding system to further optimize the winding effect, ensuring consistent roll tightness and facilitating subsequent handling and transportation of the paper rolls.
- One scanner, integrated into the production line to conduct real-time inspection of the corrugated paper’s thickness, flatness, and surface defects, ensuring that the final product meets high-strength corrugated paper quality standards.
- Drying section with dimensions of 1500×4100×4800 mm, configured with 30 cylinders and a closed gearbox drive. This design ensures efficient and uniform drying of the corrugated paper web, maintaining its structural integrity and strength while achieving the required moisture content.
- One sizing machine with a roller diameter of 750 mm, used to apply size to the corrugated paper surface. This process enhances the paper’s water resistance and surface smoothness, which is crucial for improving the performance of corrugated paper in packaging applications.
- Press section consisting of three key presses: one blind hole press, one imitation stone roller press (both with a diameter of 1300 mm), and one vacuum press (with the upper roller being a stone roller). The combination of these presses effectively removes excess water from the wet corrugated paper web. The stone rollers and blind hole design ensure uniform pressure application, while the vacuum press further enhances dehydration efficiency, laying a solid foundation for high-strength paper production.
- Wire section equipped with an open headbox, which enables easy observation and adjustment of the pulp flow, ensuring uniform pulp distribution. It features a ceramic panel (wear-resistant and long-lasting) and a wire with a length of 20 meters, providing sufficient dehydration distance to ensure the wet corrugated paper web has the required initial strength before entering the pressing section.
