Fully Automatic Toroidal Transformer Belt‑type Winding Machine

The KX‑7004B 4‑inch belt‑type fully automatic toroidal winding machine is a fine‑wire‑focused, cost‑optimized automatic winding solution, tailored for high‑volume production of small‑size toroidal coils.

Unlike general‑purpose winders, it is engineered from the ground up for 0.15–0.4mm fine enameled wire and ≤30mm OD miniature ring cores, combining soft belt‑drive dynamics with industrial‑grade PLC precision.

Designed for miniaturization, consistency, and low total cost of ownership, it excels in mass‑producing small transformers, high‑frequency inductors, and precision sensor coils. Its compact footprint + fine‑wire stability makes it the go‑to machine for electronics manufacturers prioritizing yield, quality, and affordability.

✅ Upgraded 4‑inch High‑Strength Synchronous Belt Drive (Patented‑Level Optimization)

Adopts a reinforced 4‑inch polyurethane synchronous belt with anti‑wear fiber core, delivering softer acceleration/deceleration than gear drives. Critical for fine wire: no sudden torque shocks, minimal wire stress, zero core scratching, even at high speeds. Belt tension is self‑compensating, eliminating frequent adjustments.

✅ Fine‑Wire‑Dedicated Closed‑Loop Tension Control

A micro‑precision tension feedback module monitors wire pull in real time (0.15–0.4mm range). It auto‑adjusts tension during winding, preventing breakage, loose turns, overlapping layers, or stretched wire. Result: ±0.1 turn consistency, uniform inductance, and 99.8% first‑pass yield for fine coils.

✅ Multi‑Material Core Compatibility (Differentiated from Generic Winders)

Supports ferrite, silicon steel, amorphous, and nanocrystalline cores-common in high‑frequency and medical electronics. The machine's adjustable core holder accommodates irregular mini‑cores without jamming, a key advantage over fixed‑fixture competitors.

✅ Intelligent PLC with Fine‑Wire Winding Algorithms

Pre‑loaded fine‑wire‑optimized programs for tight layers, sectional winding, and gradual tension ramping. The touchscreen offers step‑by‑step coil recipe storage (up to 50 sets)-no coding needed. Operators can switch between sensor coils, mini transformers, and inductors in <60 seconds.

✅ Anti‑Skip & Anti‑Overlap Precision Mechanism

A high‑resolution optical encoder tracks rotation with ±0.5 turn accuracy, paired with a stepper‑driven wire guide. It eliminates skip winding, cross‑over layers, or uneven spacing-critical for insulation integrity and electrical performance in high‑frequency applications.

✅ Ultra‑Compact & Production‑Ready Footprint

Benchtop design (900×900×1500mm) fits small workshops, clean rooms, and lab environments. Unlike large gear machines, it requires no special foundation-plug‑and‑play installation in <30 minutes. Ideal for low‑volume prototyping → high‑volume mass production scaling.

✅ Low‑Noise, Low‑Heat, 24/7 Continuous Operation

Belt drive runs at ≤65dB (quieter than gear machines), reducing operator fatigue. Optimized motor cooling enables non‑stop 24‑hour operation for high‑volume orders. Modular design means wear parts replacement in <15 minutes, minimizing downtime.

✅ Safety & Cleanroom‑Friendly Build

Full‑surround transparent safety guard with interlock sensors; emergency stop + fault self‑diagnosis alarm. The machine's smooth, non‑porous surface resists dust buildup-suitable for medical electronics and consumer electronics cleanroom production.
