China Zhongya Intelligent Technology Project

China Zhongya Intelligent Technology Co., Ltd

June 15, 2023- Meixin reached a significant cooperation with China Zhongya Intelligent Technology Co., Ltd. Meixin successfully provided a high-performance Edge Trim Units solution for the customer's renowned large and medium-sized paper machine project. This cooperation marks another recognition of Meixin's technical expertise in the field of high-speed, wide-width paper machine auxiliary equipment.

The paper machine served by Meixin is a benchmark large and medium-sized machine owned by Henan Zhongya Intelligent Technology Co., Ltd. This paper machine has a paper width of 4860mm, operates at a high speed of 900 meters per minute, and primarily produces 60-90 g/m² Test liner paper (T-paper). Facing the production challenges of high speed and wide width, the cleanliness of the paper edge and operational stability are critical.

1.Edge Trim Units

Function: 

The stable operation of a paper machine largely depends on whether the edge trim unit can produce clean, neat, precise, and consistent paper edges. In fact, sheet breaks occurring in the press section, or even in the drying section, size press, or coater, can sometimes originate from paper edge defects caused by the edge trim unit. The edge trim unit must be installed firmly without vibration. Its installation should allow for easy adjustment in the cross-machine direction and a certain adjustable angle in the machine direction. Furthermore, the entire unit assembly should be easy to disassemble when changing fabrics. The Edge Trim unit of Meixin is advanced edge trimming equipment and technology for the paper machine's wet end, allowing for precise adjustments both in the machine direction and cross-machine direction.

Benefits: 

Addressing the high-intensity production demands of this paper machine, the Edge Trim Unit of Meixin has demonstrated the following four core advantages in practical application, effectively solving common problems in machine operation:

Significantly Improved Paper Edge Quality: Through high-pressure, precise cutting, the paper edge is cut neatly and uniformly without fuzz. The edge quality of the paper web is significantly improved, laying a solid foundation for subsequent winding and rewinding processes.

Effective Reduction of Fiber Splashing: During high-speed operation at 900 m/min, the Edge Trim Unit optimizes the water jet shape, effectively suppressing fiber splash generated during the cutting process. This greatly improves the cleanliness and environment of the operating floor.

Substantial Reduction of Web Break Risk: The falling of accumulated pulp on the wire section is one of the main hidden dangers causing web breaks. The unit cuts cleanly and efficiently, eliminating the accumulation of edge residue on the wire, thereby significantly reducing web breaks caused by such issues and effectively increasing the machine's runnability.

Improved Winding Roll Edge Neatness: Perfect trimming directly leads to optimization of the winding process. The edge neatness of the finished parent roll is significantly improved, resulting in a tight, flat, and aesthetically pleasing finished roll appearance, enhancing the product's yield rate and market image.

Safe and Convenient Adjustment: The structural design of this edge trim unit is user-friendly. Operators can safely and conveniently adjust the trimming position during production, greatly shortening grade change time and reducing the labor intensity of operators.

A field technician from Henan Zhongya Intelligent Technology Co., Ltd. commented: "During high-speed production of T-paper, the performance of the edge trim nozzle directly affects the paper machine's efficiency and product yield. The equipment provided by Meixin not only delivers excellent trimming results but also greatly reduces web breaks and on-site splashing issues. The ends of the paper rolls are now very neat. We are very satisfied with the results of this cooperation."

This cooperation with Henan Zhongya Intelligent Technology represents another successful practice for Meixin in the field of high-speed, wide-width paper machine auxiliary equipment. In the future, Meixin will continue to dedicate itself to the R&D of precision papermaking equipment, providing customers with more efficient and stable papermaking solutions.
