Reel tip hole diameter: Ø80/125mm
Pay-off tension : mechanical friction and can be adjusted.
Electric lifting reel and electric clamping or loosening reel.
Clamp, loosen, rise, and fall actions. Ensure the reliable positioning of the wire reel. The lifting mechanism can lift and lower the left and right simultaneously or move independently. The left column can be moved independently to facilitate the clamping of the wire reel. The up and down lifting is protected by electrical limiters.

12+18 bobbin stranding cage:

Adapt bobbin size: PND630
Max rotating speed of stranding cage:

12 bobbins: 200r/min(full load loading wire),
18 bobbins : 180r/min (full load loading wire)

Stranding cage motor power:

18 bobbin : 75kw (AC)

Pitch range: 12B:40-500mm, 18B:50-600mm, Stepless adjustable
Each section of the stranding cage is driven by a separate AC motor through a special gearbox, which can rotate left and right.
Strand cage structure: The entire strand body is double-supported on the front and rear support frames, with a seamless steel pipe support in the middle. After welding, the overall frame is annealed at high temperature, aged, and cooled naturally after 72 hours.
Tension form: mechanical friction control, tension size is manually adjustable
The loading and unloading reel uses a worm gear mechanism to drive the telescopic tip, with the help of a nut gun. After the wire reel is clamped, it has a mechanical stop function to effectively ensure safe and reliable loading of the wire reel.
Wire-break parking: The system uses pulse-type wire-break protection to control each reel. The DXJ fully automatic detection device can stop the machine in time when a wire is broken or the wire is used up, and prompts show on the touch screen.
Protective fence: Equipped with a double-sided wall fixed protective net, made of porous plates and rectangular square tubes welded.
Loading reel tool: Each stranding cage is equipped with a set of loading tray lifting and turning tools
Single wire pre-former: Each section of stranding cage is equipped with a set of single wire preforming device. The single wire preforming device is used for round single wire stranding to ensure that the single wire is not loose after the conductor section is disconnected after stranding.

Close wire die holder and Compacted head

Each section of stranding cage is equipped with a closing wire die rack, Adjustable distance forward and backward
The closing wire device can complete forming or drawing one time
Inner cavity size of closing wire die base: 90x90mm
Adjustable distance of closing die base: 300mm

Meter counter: (mechanical ad electric)

Perimeter of meter wheel: Ø500mm
Max meter counting length: 9999mm
Mechanical structure meter counter. It consists of two rollers placed horizontally on the linear track bearing to compress the wire through springs. Both rollers can move freely and adaptively adjust the size of the wire. The inlet and outlet are equipped with guide rollers.
Electronic meter counting function. The meter length is displayed on the touch screen of the human-machine interface. It also has a stop function when the meter is reached. The required production length can be input on the human-machine interface. After reaching the production task, the whole machine can automatically stop and prompt on the human-machine interface.
