Structural form: the main machine adopts the overall layout of 6+12+18+24 four-section stranding cage. Each section of stranding cage is a four-section structure. The cage is carried by two large double-row roller bearings at the front and rear, and is supported and operated by the gearbox and front support. The stranding cage body is composed of stranding cage, gearbox, front support, brake system, base, drive motor, etc.

Drive mode: each section of the cage is equipped with individual drive motor to drive the stranding cage to run. The drive motor drives the gearbox to drive the cage to run through direct connection (patent). This drive system has few maintenance links, and the drive mode is direct, which can

Structural characteristics of stranding body: the frame adopts CNC laser cutting and blanking of plates, and is bent by large bending machine. This process minimizes the weld seam and improves the overall structural strength. After the overall assembly and welding, high temperature annealing treatment is used to eliminate internal stress, and then it is processed by large machine tool, to ensure concentricity, smooth operation, and high mechanical strength without deformation for a long time.

Bottom structure: the base is made of high-quality plates and rectangular square tubes, with beautiful appearance and high structural strength.

Braking system: the starting, stopping, inching and other actions of the main machine are controlled by the PLC through the air brake, frequency converter, braking resistor, etc. to ensure the synchronization of the whole machine operation

Broken wire stop machine system: equipped with advanced automatic vector pulse broken wire stop protection system, the system can stop and brake in time when the wire in the bobbin is used up or broken.

The tension of the single wire pay-off is electronically detected and controlled by electricity, and adjusted by the imported pneumatic control proportional valve, which can realize the constant tension of the single wire pay-off from the full reel to the empty reel..

The front end of each section of main cage is equipped with a single-wire e preformer device. Prefabricate stranded pitch to improve the quality of finished wire.

All wire holes and easily scratched wire positions are equipped with wear-resistant alloy wire nozzles or wire rollers.

Safety protective cover: double-side wall safety protective net made of perforated plate.

4. Electric control system:

 The power supply: three-phase, five wire system: 380V (± 10%) 50Hz, total 410kw

The machine adopts separate motor drive (the motor adopts variable-frequency motor), each AC variable-frequency motor adopts frequency converter to control speed regulation, the whole machine control is managed by Siemens programmable controller, the Siemens touch screen controls operation, and the host is started after the alarm bell rings.

Frequency converter fault alarm.

Overload protection and power supply protection of winding and arranging lines.

Air press lack protection.

Break wire protection.
