Individual Machines for Corrugated Board Manufacturing
Bridge conveyor system for smooth web transfer and consistent tension control to support continuous corrugator production
In the production of corrugated board, the overhead bridge (conveyor bridge) is mainly responsible for transporting and lifting the semi-finished corrugated paper, facilitating subsequent multi-layer lamination.
Features
- Equipped with an independent variable frequency motor lifting mechanism and PVC conveyor belt, ensuring the single-face corrugated paper maintains stable fluting during transport.
- All roller surfaces are precision ground and hard-chrome plated to enhance wear resistance and service life.
- Utilizes a vacuum adsorption tension control system with stepless adjustable airflow to accommodate different paper types.
- Features dual electric edge forming devices and an advanced positioning system to ensure precise alignment.
