Product Overview
The Overhead Corrugator Bridge is an auxiliary section of a corrugated board production line. It is designed to convey single-faced corrugated board smoothly and maintain stable board movement during the production process.
The equipment consists of a steel frame structure, lifting belt system, conveyor belt system, vacuum adsorption device, and width adjustment mechanism. It provides stable transportation and adjustable conveying conditions according to different corrugated board production requirements.
Key Features
- The bridge frame is constructed with heavy-duty steel profiles to provide a stable supporting structure for the complete equipment.
- The paper lifting system adopts a PVC conveyor belt for lifting and transferring single-faced corrugated board smoothly.
- The paperboard conveying section uses a rubber conveyor belt to provide stable transportation of single-faced corrugated board.
- The vacuum adsorption system is equipped with a variable frequency fan, allowing adjustment of suction airflow according to operating requirements.
- The paper width adjustment system adopts a reducer structure to adjust the conveying width according to different board specifications.
- The lifting system uses a variable frequency motor to provide stable power and flexible operation control.
- The conveyor rollers, lifting rollers, and guide rollers are manufactured from seamless steel pipes to ensure smooth board transportation.
- The equipment adopts a heavy-duty steel structure and modular design for convenient integration into different corrugated board production lines.

FAQ
What is an Overhead Corrugator Bridge?
An Overhead Corrugator Bridge is auxiliary equipment used in corrugated board production lines to convey single-faced corrugated board during production.
What material does the bridge convey?
The bridge is designed to convey single-faced corrugated board, not raw paper materials such as kraft liner or corrugating medium.
What is the function of the vacuum adsorption fan?
The vacuum adsorption fan provides adjustable suction airflow to support stable board conveying.
What type of belt is used on the bridge?
The equipment uses a PVC conveyor belt for paper lifting and a rubber conveyor belt for board conveying.
What are the main structural components of the bridge?
The main components include the steel frame, lifting belt, conveyor belt, vacuum fan, adjustment mechanism, rollers, bearings, and electrical control components.
