Product Overview
The Intelligent Hot Plate for Double Facer is installed in the heating section of a corrugated cardboard production line. It applies controlled heat and pressure to bond the single-face board with the liner paper, helping produce flat and well-bonded corrugated board.
The system combines a heated plate structure with an intelligent pressure control system. According to different paper grades, flute profiles and production speeds, the pressure can be adjusted automatically to help maintain stable bonding throughout the production process.
Key Features
- Adopt the internationally recognized flat-plate pressing design, providing uniform and stable pressure. The machine supports manual, automatic and networked operation modes.
- Operate with a small amount of compressed air, reducing air consumption and minimizing maintenance requirements.
- Automatically adjust the pressure according to changes in paper grade, flute profile and production speed.
- The seamless pressure plate design ensures uniform pressure distribution across the hot plate, helping prevent face liner blistering and localized poor bonding. The large pressure area and relatively low contact pressure improve heat transfer efficiency while helping maintain board flatness and bonding quality.
- According to changes in board width, the system automatically adjusts the overall ballast weight and raises or lowers the edge pressure plates, helping discharge water vapor and reduce conveyor belt edge wear.
- The pressure compensation system helps optimize pressure distribution, reduce energy consumption and maintain stable bonding quality for different flute profiles. It also helps improve board flatness and reduce flute show-through.
- The system is designed to support higher production speeds under suitable production conditions. Pressure can be adjusted according to production requirements, helping optimize energy consumption.
Core Technology of the Intelligent Hot Plate
- The pressure plate incorporates an internal control algorithm with optimized pressure control.
- Supports manual, automatic and production management system networking modes.
- Includes a zero-pressure mode suitable for lightweight paper grades.
- Provides a dedicated pressure mode during machine start-up before switching to normal production control.
- Includes a full-pressure mode to facilitate board threading during machine start-up.
Structural Design
- Simple mechanical structure with durable construction and low maintenance requirements.
- The pressure plate and mechanical structure are designed for continuous industrial operation.
- The main frame adopts high-strength H-section steel with a parallel swing-arm linkage structure.
- The hot plate is manufactured from 10 mm thick 50# steel plate with heat treatment, machining, precision grinding and surface finishing.
- Φ80 mm cylinders are installed on both sides for stable lifting and lowering of the pressure plate.
- High-temperature-resistant independent air bags provide stepless pressure adjustment and convenient maintenance.
Intelligent Pressure Control
The control system provides different pressure settings according to:
- Flute profile combinations
- Paper grades
- Paper combinations
- Customer production requirements
- Board widths
- Production speeds
This helps maintain stable pressure under different production conditions.
