China Shangshan Paper Mill Project
July 13, 2023-Meixin successfully provided an edge trim units for a large, well-known paper machine owned by China Shangshan Paper Mill. The paper machine has a paper width of 6000mm and operates at a speed of 680 meters per minute, primarily producing T paper and corrugated paper of 120-180 g/m². The edge trim units supplied by Meixin for this project has effectively improved paper edge quality, enhanced the machine's operational stability, and boosted finished product quality.
The 6000mm wide paper machine served by Meixin is the company's main production line, operating at a high speed of 680 m/min, which places extremely high demands on the precision and stability of the edge trim units.
1. Edge Trim Units
Function:In high-speed papermaking production, the quality of paper edge cutting directly affects the machine's operational stability and finished product quality. Uneven edge cutting can lead to fiber splash, stock accumulation on the forming fabric, uneven reel edges, and other issues, which in turn cause web breaks and reduce production efficiency.
Meixin's edge trim unitis specifically designed for forming section edge cutting. It adopts high-quality water jet technology to achieve neat and precise paper edge cutting, with safe and convenient adjustment. The system is equipped with water jets that allow precise lateral position adjustment, easy longitudinal cutting angle adjustment, and quick nozzle replacement. It also features a self-cleaning maintenance function for the nozzles, effectively reducing contaminant buildup. Whether for daily production adjustments or shutdown maintenance, significant time savings are achieved.
Benefits:
1. Significantly Improved Paper Edge Quality
Meixin's edge trim units use high-pressure precision water jet cutting technology, producing neat, smooth edges without burrs or ragged edges, ensuring the end-face quality of the paper rolls from the source.
2. Effectively Reduced Fiber Splash
Traditional mechanical trimming methods tend to generate flying paper dust, polluting the production environment and affecting machine cleanliness. Meixin's edge trim units replaces mechanical blades with water jets, producing no paper dust during cutting and greatly reducing fiber splash.
3. Reduced Web Breaks Caused by Stock Accumulation on the Forming Fabric
When edge cutting is uneven, scattered fibers and stock easily accumulate on the forming fabric, and when they fall off, they cause web breaks. With Meixin's edge trim units achieving neat cutting, the problem of stock accumulation on the forming fabric is effectively controlled, significantly reducing web break frequency.
4. Improved Edge Flatness of Reeled Paper Rolls
Neat edges are the fundamental guarantee for the reeling process. Meixin's edge trim units ensure that the edges of every finished paper roll are neat and consistent, with smooth end faces, providing high-quality semi-finished products for subsequent rewinding and packaging processes.
Edge Trim Units
The successful application of Meixin's edge trim units on China Shangshan Paper's 6000mm wide high-speed paper machine fully demonstrates the company's technical strength in supporting large-scale, wide paper machines. With its significant advantages of "neat trimming, dust-free cutting, stability, and reliability," the system has effectively improved paper edge quality, reduced fiber splash and web breaks on the forming fabric, and enhanced the edge flatness of reeled paper rolls, delivering tangible benefits to the customer.
