After controller is calculated, signal is fed back into lift servo motor, lift servo motor by change the output valve of motor speed come
The translational speed of control lifting buffer roll, increases or reduces the tension force of tow.Whole process belongs to closed-loop tension control, uses
The mode of PID regulation controls.Solution system is advantageous for using another benefit of PID regulation controls starting or stopping rank
Section, the problem that system concussion occurs is conducive to increasing the precision for controlling.Tension sensor only conduct on backward pull measuring roll
Force value is shown, but is compared with second tension value, and feedback compensation is carried out after going beyond the scope.
Floating roller device is tension force micro-tensioning system, keeps system tension to be maintained in lift servo electric motor starting and deboost phase
The gravity of the weight and floating roller itself of one scope of stabilization, the admission pressure in control cylinder, counterweight roller and balancing weight, gas
The active force of cylinder is balanced with the tension force of film tow.When film tow tension reduces, floating roller is moved upwards, increases the tension force of tow
Greatly, balance is then reached；When film tow tension increases, floating roller is moved downward, and reduces the tension force of film tow, is then reached flat
Weighing apparatus.When film tow tension is decreased or increased too fast, upper floating roller buffer or lower floating roller buffer impose cushion effect to floating roller, treat
The tension force of the large-scale adjusting film tow of lift servo motor.After wire wrapping wheel has been changed, the lifting of lift servo motor control is slow
Rush roller slowly to decline, its temporary film silk is received on wire wrapping wheel.Automatic filament buffer unit of the invention, can change around
During silk wheel, one section of range ability of film tow of automatic buffer, wire wrapping wheel is changed after finishing, and the perineurium auto reeling for being buffered is arrived down
On one wire wrapping wheel, the nil waste for receiving wire process is realized.Simple structure of the present invention, easy to use, high degree of automation, without increasing
Plus manual labor amount, greatly reduce production cost.
