In a corrugated board production line, a Tension Controller is mainly used to control the web tension of the base paper during
unwinding, conveying, preheating, corrugating, and laminating
processes. It is an important control component for ensuring stable
paper web running and consistent finished-board quality. Key FeaturesStable tension control: Continuously monitors web tension and automatically adjusts
braking force or driving force to maintain the desired tension
level. High-precision control: Minimizes tension fluctuations and helps prevent problems such as
loose or excessive tension, web misalignment, wrinkles, and paper
breaks. Automatic closed-loop control: Typically consists of tension sensors, a controller, and an
actuator. The system uses feedback signals to automatically
regulate tension. Fast response: Quickly adjusts the output when production speed, roll diameter,
or paper load changes. Adaptable to different paper grades: Tension parameters can be adjusted according to different paper
weights, paper grades, web widths, and production speeds. Reduced paper waste: Stable tension helps minimize web breaks, wrinkles, stretching,
and deformation, thereby reducing raw material waste. Improved board quality: Consistent web tension contributes to better flatness, bonding
quality, and dimensional stability of corrugated board. Easy integration with production lines: Can typically be integrated with PLCs, frequency converters, servo
systems, tension sensors, and other automation equipment for
centralized line control.
