China Komai Paper Mill Project
China Komai Paper Mill
August 9, 2023-Meixin successfully provided a comprehensive intelligent solution covering five core systems for a high-strength corrugated paper machine owned by China Komai Paper Mill. The paper machine has a paper width of 4600mm and operates at a speed of 700 meters per minute, primarily producing high-strength corrugated paper of 110-160 g/m². Meixin supplied the project with the dryer fabric cleaner, water jet reel turn-up system, water jet tail cutter for wet end, ropeless tail threading system, and edge trim units, comprehensively improving the paper machine's operational efficiency, paper quality, and production safety.
1. Dryer Fabric Cleaner
Function:Meixin deployed the PF·Clean intelligent online dryer fabric cleaner. The system is equipped with high-efficiency cleaning heads installed in the wrap angle area between the dryer fabric and guide rolls, maintaining a reasonable gap from the fabric. High-pressure water nozzles spray the fabric surface at a specific angle to loosen and detach adhesive contaminants. Front and rear air knives assist by blowing off the contaminants, while a vacuum extraction system discharges them outside the paper machine. An external air knife thoroughly removes residual moisture after cleaning.
Benefits:
Online cleaning of dirty dryer fabric during normal production without shutdown
No chemical additives throughout the process, environmentally friendly and pollution-free
Improves and maintains dryer fabric permeability, significantly enhancing drying efficiency
Eliminates web breaks, grooves, marks, and holes caused by dirty dryer fabric
Reduces rewinder breaks caused by stickies-related paper defects
Improves production efficiency and paper machine running performance
Helps increase machine speed and extends dryer fabric service life

2. Water Jet Reel Turn-up System
Function:Meixin's high-pressure water jet reel turn-up system's beam is installed above the reel. An ultra-high-pressure water generation system produces high-pressure water, which is ejected as high-quality water jets through ultra high-pressure nozzles. The transfer beam is equipped with two sets of water jet heads. The water jets move at high speed to cut a paper tip while spraying an appropriate amount of adhesive, allowing the paper tip to quickly adhere to the new reel spool for high-quality reel change.
Benefits:
Fully automatic reel change, maximizes operator safety and avoids the risk of being pulled into the reel
Extremely short transfer process, paper web smoothly transfers to the new spool with no bottom wrinkles and minimal waste paper
Transfer success rate close to 100%, effectively improving finished paper yield by 0.5%–3%
One-time investment with long-term benefits
Suitable for corrugated paper, kraft paper, kraft linerboard, whiteboard paper, coated board, newsprint, cultural paper, and tissue paper; suitable for almost all paper machine speeds

3. Water Jet Tail Cutter for Wet End
Function:Meixin's water jet tail cutter for wet end features stable and reliable cutting of tail threading strip and full sheet spreading. The system is equipped with one nozzle that produces a high-quality tail cutter to cut the paper web and form a tail strip. When full sheet spreading is required, a high-precision moving carriage carrying the cutting nozzle moves to the outside of the paper web on the drive side of the paper machine to complete the tail threading and sheet spreading.
Benefits:
Automatic start and stop
Equipped with wireless communication module for remote wireless operation
Automatically and quickly executes return command upon receiving a web break signal
Maximizes prevention of broke accumulation in the dryer section and press section
Smooth water jet movement, improving the success rate of tail threading and sheet spreading
PLC and inverter servo combination for intelligent and precise tail threading positioning
Overall material of 304 stainless steel, durable and reliable

4. Ropeless Tail Threading
Function:Meixin's ropeless tail threading system abandons the traditional threading rope method and adopts fast and efficient automatic tail threading technology, greatly improving the stability and efficiency of the tail threading process.
Benefits:
Higher tail threading stability
Shortens tail threading time, improves tail threading efficiency
Effectively increases paper machine production capacity
Reduces the number of operators required for tail threading
Lowers the skill requirements for operators
Reduces safety hazards in tail threading operations
Ropeless Tail Threading
5. Edge Trim Units
Function:Meixin's edge trim units achieves clean paper edge cutting with safe and convenient adjustment, providing strong protection for paper web edge quality.
Benefits:
Significantly improves paper edge quality
Effectively reduces fiber splash
Significantly reduces web breaks caused by fallen accumulated stock on the forming fabric
Effectively improves the edge flatness of the reel spool
Edge Trim Units
The five intelligent systems provided by Meixin for China Komai Paper Mill cover the complete production chain from the forming section to the reel-up section, achieving comprehensive optimization in key areas such as dryer fabric cleaning, reel turn-up efficiency, tail threading automation, and edge trimming quality. The successful implementation of this project has not only significantly improved the paper machine's operational efficiency and paper quality but also further demonstrated Meixin's technical expertise and system integration capabilities in the field of intelligent paper machine solutions.
In the future, Meixin will continue to deeply cultivate the paper industry, providing more efficient, intelligent, and environmentally friendly solutions for customers around the world.
