High-Speed 4-Shaft Rewinder for Precision Household & Food-Grade Foil Rolls
Driven by fast-growing global demand for household kitchen foil, food service packaging rolls and salon aluminum foil, foil converters are under constant pressure to increase output, improve roll consistency, and meet strict food hygiene standards. Traditional semi-automatic slitting and rewinding equipment often brings bottlenecks: low production speed, inaccurate length control, frequent wrinkling, high labor reliance, and difficulty in complying with food-contact safety requirements.
The HAFA890S fully automatic aluminum foil slitting and rewinding machine is an engineered solution for soft foil material converting. Built with advanced PLC control and servo-driven systems, it realizes fully automated production from large mother roll unwinding to finished small roll discharging. It helps foil manufacturers achieve higher throughput, tighter quality control, lower labor costs and reliable food-grade production compliance.
Integrated Machine Structure: 7 Core Units for Smooth, Continuous Operation
This machine adopts a compact, ergonomic layout with seven functional modules working in seamless coordination. All processes are centrally controlled to avoid manual intervention and ensure stable, consistent production quality.
1. Precision Decoiling Unit
The unwinding section is equipped with a centering and horizontal adjustment mechanism to align the mother roll precisely and keep its axis parallel with the rear rollers.
- Centering and horizontal adjustment stroke: ±20mm
- Supports maximum unwinding diameter of φ800mm
- Compatible with raw roll core inner diameters of φ75mm and φ150mm
- Equipped with magnetic powder brake for stable tension control
2. Stretch & Flatting Roller System
Multiple sets of rear rollers and multi-stage stretching processes are arranged between the unwinding unit and traction roller.
- Eliminates tension pulsation and wrinkling caused by out-of-round mother rolls
- Ensures flat, wrinkle-free aluminum foil enters the winding section
- Reduces scrap rate and improves finished roll surface quality
3. Stable Foil Traction System
As the main power unit for foil transmission, the traction system adopts an AC variable frequency motor with chain drive for steady, gapless conveying.
- Pneumatic rubber pressing roller with adjustable pressure
- Stepless speed regulation for flexible production arrangement
- Reliable and low-maintenance transmission structure
4. 4-Shaft Rotary Automatic Rewinding System (Core Unit)
This pneumatic sealed rotary squirrel-cage structure is the core of the machine, automatically completing winding, handover, cross-cutting and roll discharging.
- Controlled by imported electromagnetic clutch, with freely adjustable slip torque for stable winding tension
- Winding speed up to 50m/min, settable and displayed on the operation panel
- High-precision machining and assembly for long-term reliable operation
- Supports quick specification adjustment for different paper core sizes
5. Automatic Tube Feeding System
The system integrates automatic paper tube loading, gluing and positioning functions for fully automatic core feeding.
- Slope electric vibrating loading bin ensures smooth, continuous tube supply
- Double-sided active structure with 30–35mm ring offset width
- Adjustable gluing layer thickness by regulating spring pressure on rubber rollers
6. Automatic Discharging & Tail Winding System
Finished rolls are discharged automatically through a slope receiving structure and stainless steel chain take-up table.
- Rolls roll down the slope after blanking to complete tail winding
- Finished rolls fall accurately into the take-up table via linkage mechanism after cross-cutting
- Automatically conveyed out by the chain belt for direct packaging
- Driven by imported AC servo motor, with intermittent motion controlled by PLC in sync with the squirrel-cage
7. Built-In UV Disinfection System
Installed between the stretch roller and traction roller, the UV system disinfects both front and back sides of the aluminum foil during production.
- Ensures hygiene compliance for food and packaging applications
- Equipped with 2 pieces of 20W UV lamps
- Easy lamp replacement and maintenance by opening the front door of the disinfection box
