China Huaxing Paper Packaging Project

China Huaxing Paper Packaging Co., Ltd.

Meixin successfully delivered an integrated intelligent solution for a high-strength corrugating paper machine at China Huaxing Paper Packaging Co., Ltd. The paper machine has a web width of 4,400 mm and operates at speeds of up to 500 m/min, primarily producing high-strength corrugating paper with basis weights ranging from 80 to 140 g/m².

For this project, Meixin supplied three key systems: a ropeless tail threading system, a wet-end water jet tail cutting system, and a dryer cylinder release agent spraying system. Together, these solutions significantly improve tail threading efficiency, operational stability, and production safety.

1. Ropeless Tail Threading System

Traditional rope-based tail threading systems have long faced challenges such as low threading efficiency, rope slippage and wear, and speed mismatches that can easily cause web breaks. These issues result in frequent and prolonged machine downtime, adversely affecting production stability and paper quality. Particularly on medium-and high-speed paper machines, conventional rope-based threading methods can become a major bottleneck to production efficiency.

Meixin's ropeless tail threading system adopts advanced automatic threading technology, eliminating the need for traditional threading ropes. It enables fast, stable, and reliable paper web transfer, significantly improving threading efficiency and process stability.

Key Benefits:

Enhanced tail threading stability and reliability

Shorter threading times and higher threading efficiency

Increased paper machine production capacity

Reduced manpower requirements for threading operations

Lower skill requirements for operators

Improved operational safety and reduced workplace risks

2. Wet-End Water Jet Tail Cutter

Meixin's wet-end water jet tail cutter ensures reliable tail cutting and full-width web spreading. The system is equipped with a high-performance water jet nozzle that precisely cuts the paper web into a threading strip. When full-width web spreading is required, a high-precision moving carriage carries the cutting nozzle across the web and moves it to the drive-side edge of the paper machine, completing the threading and web-spreading process.

Key Benefits:

Automatic start/stop operation

Wireless communication module for remote operation

Automatic and rapid response to web break signals, returning the system to the designated break position

Minimizes broke buildup in the press and dryer sections

Smooth and precise nozzle movement, improving threading and web-spreading success rates

PLC and inverter-based servo control for intelligent and precise positioning during threading

Constructed from 304 stainless steel for durability and reliability

3. Dryer Cylinder Release Agent Spraying System

During corrugating paper production, stickies and paper dust can accumulate on dryer cylinder surfaces, causing paper sticking, increased web break frequency, and higher steam consumption. These problems directly affect paper machine efficiency and energy consumption.

Meixin's dryer cylinder release agent spraying system is specifically designed to apply release agents to dryer cylinder surfaces. Equipped with one or two movable spray nozzles, the system evenly distributes the release agent across the target surface, forming a protective release layer that helps prevent the adhesion and accumulation of stickies, paper dust, and other contaminants.

Key Benefits:

Effectively reduces paper machine web breaks

Helps reduce steam consumption

Supports higher paper machine operating speeds

Improves production efficiency and reduces manufacturing costs per tonne of paper

An Integrated Solution for Greater Productivity and Reliability

Dryer Cylinder Release Agent Spraying System

The three systems supplied by Meixin for China Huaxing Paper – the ropeless tail threading system, wet-end water jet tail cutter, and dryer cylinder release agent spraying system – address key operational challenges across the paper machine, from tail threading and wet-end web cutting to dryer cylinder surface treatment.

The ropeless tail threading system and wet-end water jet tail cutter work together to improve threading automation and success rates, reducing dependence on manual operations and minimizing operational risks. Meanwhile, the dryer cylinder release agent spraying system helps prevent paper sticking and reduce web breaks at the source, while lowering steam consumption.

Working together, these three systems enhance overall paper machine efficiency, operational stability, and product quality, delivering tangible production benefits to the customer.

Moving forward, Meixin will continue to provide efficient, intelligent, and reliable equipment solutions for paper mills producing high-strength corrugating paper, linerboard, coated white board, and other paper grades.
