When optical fiber high-speed cruising under several high-speed rotating driving wheels.It wherein provides and keeps appropriate between two driving wheels of tension
Rotational speed difference can make the optical fiber between two driving wheels bear certain tension, in this way to achieve the purpose that test mechanical strength.Work as light
Fine mechanical strength is not enough to bear the fibre that can break when screening tension, and screening needs to stop at this time.Due to Processes and apparatus level, screening machine
Speed be also continuously improved, have reached 2500 ~ 3000m/min at present, when the screening machine in high-speed cruising need to stop because of disconnected fibre,
Often it is not easy quickly to stop since the diameter and quality at pay-off barrel end are larger, it will cause disconnected fibres to lash pay-off barrel surface, from
And damage the optical fiber not screened.
Quickly stop when the occurring disconnected fine braking moment of needs of screening machine is up to 500Nm, typically now uses motor
The mode of control parking or brake.When being stopped using motor control, to make motor export sufficiently large braking moment, often
The maximum rated power for reaching tens of kilowatt is needed, and often only needs several kilowatts of rated power i.e. when screening machine normal operation
Can, therefore equipment installed capacity will increase using energy consumption of electrical machinery braking, it is less economical and not energy-efficient；When using brake,
Solenoid-driven aerodynamic brake piece is controlled after the generally disconnected fibre of existing method, this method can reduce equipment installed capacity, but be
Often primary output compared with large braking torque to mechanical equipment and fiber reel causes larger abrasion and wound to the brake of guarantee fast and stable
Evil.
