1400/3 bobbin stranding cage
4.2.1 Pay off bobbin size:PN1400
4.2.2 Max load capacity:3T each bobbin
4.2.3 Max speed :50r/min
4.2.4 Pitch range:500-3600mm (stepless adjustable on PLC)
4.2.5 Driving motor power: 45KW(AC)
4.2.6 Back twist structure : planetary gear
4.2.7 The winch is operated through the HMI touch screen, and the
programmable controller PLC coordinates and controls the start,
stop, jog and other operations of the cage.
4.2.8 The 1250/3 stranding cage is supported by the reduction box
and the large bearing seat. The main shaft is a whole piece of
high-quality seamless steel pipe, driven by a separate AC variable
frequency motor, and has the left and right stranding function.
100% back-twist twisting is realized through the planetary gear
mechanism.
4.2.9 The whole machine is designed for high-speed operation,
without tugboat load, and runs through the reduction box and the
internal bearing of the large bearing seat. The interior of the
reduction box is sprayed and lubricated by the oil pump motor; oil
supply, lubrication and cooling are circulated through the oil pump
motor (patented design).
4.2.10 The back-twist mechanism of the stranding cage adopts
planetary gear back-twist, which can withstand large torque.
4.2.11 The cage pre-twisting mechanism is driven by 3 geared motors
and can be adjusted online.
4.2.12 The stranding cage is independently driven by a 45KW AC
motor with a built-in encoder. The encoder operates in a
closed-loop control system and is coordinated and controlled by the
programmable logic controller PLC and each unit.
4.2.13 Pay-off tension: The reel frame provides the tension
required for pay-off through mechanical belt friction, and the
tension can be adjusted manually.
4.2.14 Braking system: winch cage braking through: air pressure
brake, frequency converter, braking resistor, etc. are coordinated
by PLC to complete the braking process. The entire braking process
is synchronized with the whole machine to ensure stable pitch.
4.2.15 There are 12 sets of filling rope pay-off racks at the
outlet end of twisted body.
4.2.16 Various protections such as drive motor failure alarm, large
bearing over-temperature alarm, circulating oil supply shortage
alarm, etc. When a fault occurs, the man-machine interface prompts
and displays specific fault information, which is convenient for
troubleshooting and maintenance.
1250/1+1+3 Wire Cable Laying Up Machine
4.9 Electrical control system
4.9.1 The electric control part is composed of operation cabinet,
touch screen, etc., and each unit is equipped with corresponding
control buttons such as emergency stop, inching, brake release,
etc. for easy operation.
4.9.2The control cabinet is designed with good mechanical
performance and dust-proof performance, and is equipped with an
appropriate amount of forced ventilation fan.
4.9.3 The power supply is three wire five phase system :
380V(±10%)50HZ.
4.9.4 Total installed power : 110KW
4.9.5 Motor protection function: the electrical control circuit is
designed with functions such as phase loss, overload and
overheating protection to prevent motor damage.
4.9.6 The alarm fault information can be queried online on the
touch screen or Ethernet, with the function of alarm fault storage,
and the historical operation information can be set to be deleted
only by personnel with management authority.
4.9.7 All drive motors are designed with encoders, and the encoder
feedback operates in the closed-loop control system.
4.9.8 The unit adopts PLC for unified and coordinated control
operation. Touch screen HMI is adopted for operation. Simple and
convenient operation.
