China Yuecheng Zhongxin Paper Mill Project
China Yuecheng Zhongxin Paper Mill
September 13, 2024-Meixin successfully provided a ropeless tail threading system for a specialty thin paper machine owned by China Yuecheng Zhongxin Paper Mill. The paper machine has a paper width of 3600mm and operates at a speed of 500 meters per minute, primarily producing specialty thin paper of 25-70 g/m². The ropeless tail threading system supplied by Meixin for this project has effectively improved the paper machine's operational efficiency, tail threading stability, and production safety.
1. Ropeless Tail Threading
Function: In traditional papermaking production, the tail threading rope system has long exhibited numerous drawbacks—low threading efficiency, frequent rope detachment and severe wear, and issues with speed differentials that easily lead to web breaks during threading, resulting in prolonged and frequent downtime, seriously affecting the stability of the paper machine's operation and product quality. Particularly on medium to high-speed paper machines, traditional tail threading methods have become a bottleneck restricting production efficiency.
Meixin's ropeless tail threading system adopts fully automatic tail threading technology, eliminating the traditional threading rope approach. Through precise automatic control and air-assisted technology, it enables rapid and stable transfer of the paper web from the press section to the dryer section, and from the dryer section to the reel section. The system can be applied across the entire machine from the wet end to the reel, suitable for all paper grades and machine speeds.
Benefits:
Higher tail threading stability: Fully automatic control and precise positioning ensure smooth and reliable web transfer
Shortened tail threading time and improved efficiency: Automated threading greatly reduces recovery time after web breaks
Effectively increases paper machine capacity: Improved threading efficiency directly translates into increased production output
Reduces the number of operators required for tail threading: High automation reduces labor dependence
Lowers the skill requirements for operators: The system automatically completes threading, eliminating the need for highly experienced manual operation
Reduces safety hazards in tail threading operations: Eliminates operator exposure to high-speed rotating equipment and the safety risks associated with threading ropes
Ropeless Tail Threading
Meixin's ropeless tail threading system, with its fully automatic control and precise web transfer technology, has successfully addressed the long-standing pain points of low efficiency, poor safety, and high operational skill requirements associated with traditional threading rope methods in specialty thin paper production. The successful implementation of this project has not only improved the paper machine's operating efficiency but also once again demonstrated Meixin's professional expertise in the field of tail threading automation.
