Industrial-grade automatic string winding machine designed for oil filter and separator element reinforcement. Utilizing adjustable PLC touchscreen control and precise tension mechanics, it wraps cotton yarn, glass fiber, or polyester thread uniformly around pleated filter elements. Ideal for preventing pleat deformation in high-velocity oil filtration systems. For flat tape or belt wrapping reinforcement, please view our Automatic Oil Filter Belt Winding Machine.
This professional Automatic Oil Filter String Winding Machine is designed to wind high-strength string or thread around the outer pleats of oil filter elements and air-oil separators. By providing continuous, uniform external wrapping, the machine reinforces the filter pleats, ensuring they do not collapse, bunch, or deform under high-pressure and high-velocity oil flow conditions.
Featuring a digital PLC touchscreen control system and a precise mechanical tension regulator, this machine ensures that the wrapping material—whether cotton, polyester, or fiberglass—is applied with consistent tightness. It is an essential production station for manufacturers of automotive spin-on filters, industrial hydraulic filters, and air compressor separators aiming for heavy-duty structural durability.
Technical Specifications
The factual technical parameters of the string winding machine are detailed below to ensure exact mechanical compatibility with your filter production lines:
The rotation of the filter chuck is fully synchronized with the lateral movement of the string guide. This advanced alignment ensures that the string is wound with a perfectly uniform spiral pitch, delivering consistent and professional-grade reinforcement across the entire length of the filter element.
2. Multi-Material String Compatibility
Designed for versatility on the factory floor, the machine easily handles various wrapping materials, including industrial cotton yarn, high-tensile polyester thread, and temperature-resistant glass fiber string, allowing you to match the reinforcement to the filter’s operating environment.
3. Precision Tension Control System
To prevent the string from snapping or crushing the delicate pleated filter media, the feeding rack is equipped with an adjustable tension controller. This maintains stable, constant tension on the string spool throughout the entire automatic wrapping cycle.
4. User-Friendly Touchscreen PLC Interface
The operator can program, adjust, and monitor winding speeds, spiral pitch spacing, and overall cycle times directly on the touchscreen HMI. The system supports multi-recipe storage, allowing rapid adjustments for different filter models without mechanical downtime.
