Fiber winding machine is a device used to orderly wind continuously produced fiber materials (such as synthetic fibers, glass fibers, carbon fibers, natural fibers, etc.) through a mechanical transmission system. Its core function is to transform loose fiber bundles into regularly formed roll bodies, which are convenient for subsequent processing, transportation, and storage. According to different process requirements, fiber winding machines can be divided into the following categories:
-By driving mode: mechanical (gear/belt transmission), servo motor driven;
-According to the winding form: parallel winding machine, cross winding machine;
-According to the degree of automation: manual operation type, semi-automatic type, fully automatic intelligent type;
-According to applicable materials: universal type (suitable for multiple fibers), specialized type (such as carbon fiber specific rewinder).
Application fields of fiber winding machine
Fiber winding machines are widely used in the following scenarios:
-Textile industry: finished winding of synthetic fibers such as polyester, nylon, and acrylic;
-Composite material manufacturing: winding of carbon fiber and glass fiber prepreg;
-Production of non-woven fabrics: coiling of melt blown non-woven fabrics and hydroentangled non-woven fabrics;
-Special material processing: precision winding of aramid fibers and ultra-high molecular weight polyethylene fibers.
The core value of fiber winding machine
-Improve production efficiency: achieve continuous production and reduce manual intervention;
-Ensuring product quality: By precisely controlling tension and winding angle, fiber damage is avoided;
-Reduce labor intensity: replace traditional manual winding and reduce labor costs;
-Optimize warehouse logistics: Standardized roll packaging forms facilitate stacking and transportation.

Principles for Setting Key Parameters
Design of winding speed gradient
-Low speed range (0-30%): The starting speed is set to 30% of the rated value to prevent initial layer slip;
-Acceleration stage (30-70%): increase to the working speed according to a linear law;
-Constant speed range (70-90%): Maintain stability until approaching full roll;
-Deceleration section (90-100%): Reduce speed in advance to minimize impact vibration.
Adjustment of directional sensitivity
-Distance between photoelectric switches: Two pairs of detection devices are spaced 5mm apart to ensure timely triggering of steering commands;
-Reversing delay time: set to 0.1-0.3 seconds to avoid edge collapse caused by inertia;
-Reverse acceleration: controlled within ± 0.5g to reduce mechanical impact.
Key monitoring points during the trial operation phase
-Inspection system: The first 5 rolls of continuous production must be fully inspected, and the following indicators should be recorded:
-Winding hardness (Shore A type): 65 ± 3 degrees;
-End face flatness: runout ≤ 0.5mm;
-Weight consistency: Single roll difference ≤ ± 0.3%.
-Abnormal sound recognition: using a stethoscope to detect abnormal bearing noise (high-frequency whistling) and poor gear meshing (periodic clicking sound);
-Temperature inspection route: Measure the temperature of the motor casing, gearbox body, and inverter cooling fins every half hour, and do not exceed the ambient temperature+40 ℃.
