What are the technical characteristics of high-performance fiber winder for spinning equipment?

The core of high-performance fiber winder in spinning equipment is designed around the directions of precise tension control, precise winding forming, high-speed and stable operation, low damage and automatic winding change, intelligent digital control, etc., to meet the winding requirements of high-performance fibers such as aramid fiber, carbon fiber and ultra-high molecular weight polyethylene. The following is detailed from the key technical dimensions:

Precise tension control technology

Electronic closed-loop tension adjustment: strain gauge tension sensor (accuracy 1%) is adopted to adjust the torque of magnetic powder clutch or servo motor in real time through PID algorithm. The tension can be accurately adjusted online, and the fluctuation is controlled within 2% of the set value, so as to meet the low tension or constant tension requirements of different fibers.

Pneumatic tension compensation mechanism: equipped with pneumatic controllable tension rod and tension balance wheel, combined with the feedback of angle sensor, dynamically compensate the tension fluctuation caused by the change of winding diameter to ensure the same tension from inside to outside of large winding diameter.

Self-adaptation of contact pressure: the pressure of the wire pressing roller decreases linearly with the increase of the winding diameter, so as to avoid excessive extrusion of the outer fiber, ensure uniform package hardness and stable molding.

Precision winding and guide wire technology

Electronic variable winding ratio: set and adjust the winding ratio in real time through PLC programming to adapt to different fiber specifications and package patterns. When winding with large winding diameter, the shape is neat and the edge does not drop, and the control accuracy of winding angle reaches 0.1.

Servo-driven reciprocating guide wire: the traverse mechanism is driven by servo motor, matched with grating ruler with resolution of 0.01mm, and the travel error of wire arrangement is ≤ 0.1 mm. The surface of guide wire wheel is treated with ceramic coating or orange peel to reduce fiber friction damage and improve durability.

Low-contact wire feeding structure: such as two-wheel wire feeding channel design, reduce the contact point between fiber and guide wire parts, reduce friction coefficient, and avoid pilling or fracture on the surface of high-strength fiber.

High-speed stability and large coil diameter adaptation

Independent double motor drive: spindle shaft and traverse mechanism are driven independently, which reduces the error of transmission chain, the response frequency reaches 2kHz, and the winding speed can reach 800-1500m/min, which is suitable for high-speed spinning production line.

Inflatable shaft clamping system: the winding core adopts pneumatic expansion head, which is suitable for 76-152mm inner diameter paper pipe/plastic pipe, which is convenient for loading and unloading, and the winding core runout is ≤0.05mm, ensuring high-speed rotation stability.

Forming ability of large winding diameter: the maximum winding diameter can reach 300-320mm. By setting the parameters of winding diameter/length, accurate winding with fixed length and fixed diameter can be realized, which meets the requirements of efficient production of large spindles.

Automatic coil changing and efficient operation technology

Automatic coil changing of double spindles: the spare spindle shaft is accelerated synchronously in advance, and the success rate of coil changing is over 99% by switching stations through the rotating disc. There is no broken wire or waste wire in the coil changing process, which saves labor cost.

Multi-mode rewinding trigger: it supports three trigger modes of length, diameter and weight, adapts to the winding counting requirements of different fibers, and the rewinding time is less than or equal to 3 seconds, which significantly improves the production efficiency.

Pneumatic-assisted doffing: equipped with pneumatic doffing push rod, it can automatically loosen and push after full winding, reducing labor intensity and adapting to continuous production of single-layer or double-layer multi-spindle layout.

Intelligent digital control and monitoring

PLC+servo drive architecture: PLC and servo system of Siemens, An Chuan and other brands are adopted, and PROFINET/EtherCAT communication is integrated, which supports the storage of more than 10 kinds of process parameters, and the fiber variety switching is fast and efficient.

Full-process state monitoring: it has the functions of yarn breakage, full package and pre-alarm, displays data such as speed, length and output in real time, supports remote data acquisition and fault diagnosis, and is more convenient to maintain.

Safety protection design: emergency stop circuit series connection, overload protection, protection door interlock, etc., in line with IEC 60204-1 standard, to ensure operational safety during high-speed operation.

Structural optimization of special fiber

Wear-resistant and corrosion-resistant design: stainless steel or ceramic materials are used for the parts contacting with fibers, which meet the chemical stability requirements of high-performance fibers such as basalt and carbon fiber and prolong the service life of the equipment.

Low-energy transmission design: reduce intermodal links, reduce energy consumption by independent driving of double motors, and some models adopt frequency conversion control, which reduces energy consumption by 15%-20% compared with traditional models.
