▲Bridge conveyor correct error device system:For 5-ply
The system is divided into 1 branches: paper inspection, 3 layer,
two layer bridge inspection guide direction machine, a
program-controlled electric box and ground control interface of
five parts.
Principle introduction
The bridge tension control system principle of Principle
introduction
The system adopts pneumatic brake tension control, application of
slip band brake roller and the other 3 branches of the guide roller
of "zigzag" arrangement, the single side corrugated roller friction
brake in a certain angle, the friction and the friction roller
surface, tight state through the gas pressure regulating valve
control the size of the flow of multi point brake to control the
brake is a single side corrugated roller speed, lower friction,
resistance is greater, the greater the tension of single corrugated
paper. On the other hand, the brakepressure decreases, and the
brake resistance decreases, the friction coefficientde creases,
paper tension decreases.
Tension control configuration
Tension control configuration tension control configuration
The system includes: two on the lower layer of the brake friction
roller and the guide roller is two layers, each layer includes more
than 1 point brake
(installed on the drive side), 1 brake roller, branch guide roller
and the ground control interface consists of several parts.
▲The seven layer bridge tension control system contains two on the
lower layer and the two layer of brake friction roller guide
roller, a total of more than 2 points, the 3 brake brake wheel, 9
guide roller and a ground operation control interface box.
▲The tension control system is designed with manual adjustment of
gas flow throughthe pressure regulating valve, pressure table
numerical display, manuallyoperated control.
▲High - tension control system is through the transmission speed
signal byphotoelectric detection, automatic tension control program
design of PLC default,through the touch screen can modify the
tension mode and parameters so as to realize the automatic
operation.
