Cultural paper machines are specialized papermaking equipment used to produce cultural papers, which mainly include writing paper, printing paper, and copier paper.
These papers are widely used in publishing, office work, and education.
Basic Definition and Function
A cultural paper machine is a complete, integrated system that continuously produces paper webs from a pulp suspension meeting papermaking requirements,
Through processes such as dewatering, mechanical pressing, and drying.
Its core function is to achieve efficient and automated conversion of pulp into finished paper.
Cultural paper machines typically include the following key parts
Headbox: Evenly distributes the pulp onto the forming wire.
Forming Section (Wire Section): The pulp is dewatered here to form a wet paper web.
Common types include Fourdrinier, cylinder, and twin-wire forming sections.
Press Section: Applies pressure to the wet paper sheet using rollers to further dewater it.
Drying Section: Uses drying cylinders to dry the paper sheet to the desired dryness (usually 92%-94%).
Calendering and Winding Section: Finishes the paper surface to improve smoothness and winds the finished paper into rolls.
Auxiliary Systems: Including white water recovery, vacuum, lubrication, heat recovery, and automated control systems, to ensure efficient and environmentally friendly operation.
Cultural Paper Machines Technical Characteristics and Development Trends
Large-scale and High-speed: Cultural paper machines can have a width of over 10 meters and a speed exceeding 1000 meters per minute, enabling large-scale continuous production.
Intelligent and Digital: Utilizing DCS (Distributed Control System) and intelligent monitoring systems to achieve automated and precise control of the production process, improving quality and efficiency.
Green and Low-carbon: Focusing on energy saving and emission reduction, using 100% wood pulp raw materials
And advanced wastewater and exhaust gas treatment technologies to achieve “increased production and reduced pollution.”
The company covers all aspects of the research, development, and production of energy-saving and environmentally friendly papermaking machinery and core key components.
All key processes utilize automated batch production equipment, placing it at the forefront of international advanced technology.
Meanwhile, the company’s pressure vessel manufacturing passed provincial-level acceptance in April 2023.
The cultural paper machine meets EU CE certification requirements, and its design and manufacturing comply with ASME standards.
This work has laid a solid foundation for the company’s large-scale entry into domestic and international markets.
