The machine is a specialized automated equipment used to manufacture the internal support core tube (central tube) of filter cartridges. It continuously spirally winds metal strip materials according to a preset pitch to form a cylindrical support structure with high strength and uniform opening distribution.
The produced central tubes are widely used in:
- Industrial dust filter cartridges
- Air filtration systems
- Hydraulic oil filters
- Water treatment cartridges
- Power plants and chemical filtration systems
Description
Working Principle
- Material Feeding System
Automatically feeds metal strip materials (steel strip / galvanized strip / stainless steel strip).
- Forming Guidance System
Guides the strip to control spiral angle and tube diameter.
- Spiral Winding Process
The strip is continuously wound into a tubular structure with a fixed pitch.
- Locking / Welding (Optional)
Spot welding, seam welding, or mechanical locking is used to secure the structure.
- Automatic Cutting System
The finished tube is cut into required lengths automatically.
Features
- Advanced Spiral Interlocking Technology
Utilizes a precise mechanical seam-folding lock that ensures the tube remains rigid and pressure-resistant under extreme operating conditions, preventing seam burst or leakage.
- High Automation & Precision
Equipped with a CNC control system, allowing operators to easily adjust tube diameter, cutting length, and winding speed via a user-friendly HMI touch screen.
- Burr-Free Flying Cut-Off
Integrates an automatic tracking saw or hydraulic cutting system that cuts the finished tube to exact lengths on the fly, ensuring smooth, burr-free edges without interrupting continuous production.
- Material Versatility
Highly adaptable to a wide range of metal strips, including Galvanized Steel (GI), Stainless Steel (SUS 304/316), and Aluminum Alloy, handling both perforated and solid strips seamlessly.
- Flexible Diameter Ranges
Features quick-change tooling designs, enabling fast transitions between different tube diameters to meet diverse filter specification requirements.
