China Xingdong Technology Project
China Xingdong Technology Co., Ltd
July 5, 2025-Meixin successfully provided an intelligent cleaning solution for a large paper machine owned by China Xingdong Technology Co., Ltd. The paper machine has a paper width of 4800mm and operates at a speed of 1000 meters per minute, primarily producing high-strength corrugated paper of 60-120 g/m². Meixin supplied the project with a vacuum roller cleaning system and a wire cleaning system, comprehensively improving the paper machine's operational efficiency and production stability.
China Xingdong Technology Paper Machine
1. Vacuum Roller Cleaner
Function: Meixin's vacuum roller online cleaning system is specifically designed to keep vacuum roller holes clean. It can clean vacuum roller holes online during normal paper machine production, effectively reducing hole plugging.
Benefits:
Online cleaning during normal paper machine production without affecting production
Keeps vacuum roller holes open, stabilizing paper machine operation
Improves wet end running stability
Maintains roll surface hole cleanliness and vacuum roller performance
Reduces web breaks and shutdown maintenance caused by plugged vacuum roller holes
Improves paper machine operating efficiency, thereby increasing production output
Vacuum Roller Cleaner
2. Wire Cleaner
Function: Meixin's intelligent online wire cleaning system uses high-performance filtered clean water, which generates high-pressure water through a high-pressure pump station. The online cleaning machine is equipped with a high-efficiency cleaning head that traverses across the machine width. The cleaning head's movement is controlled by a PLC, and operators can set parameters via a visual touchscreen. The cleaning head sprays high-pressure water at a specific angle onto the paper machine clothing (forming fabric), achieving precise cleaning of the fabric and ensuring normal, clean production.
Benefits:
Effective water and energy savings
Reduces or eliminates the need for chemical cleaning, more environmentally friendly
Completely solves the problem of uneven moisture distribution and fabric cleaning streaks caused by local nozzle clogging
Better paper machine running performance and dewatering performance, helps increase machine speed
Dense cleaning method effectively removes regional contaminants and individual marks
Reduces web breaks in the forming section
Significantly reduces water mist in the forming section
Easy cleaning or nozzle replacement without shutdown
Wire Cleaner
With its mature online cleaning technology, Meixin has provided efficient and stable cleaning support for China Xingdong Technology's high-speed corrugated paper machine. The vacuum roller cleaning system significantly reduces the risk of web breaks in the wet end, while the wire cleaning system improves forming section dewatering efficiency while saving water and energy. The synergistic application of the two systems helps customers reduce unplanned downtime and increase overall paper machine efficiency. Meixin will continue to be driven by innovation, helping paper mills achieve green, intelligent, and efficient sustainable development goals.
