Equipment and process details
Final parameters and system boundaries are confirmed against materials, process targets, capacity and site conditions.
Key Features
- Tailor-Made Hot Air Distribution System: Provides uniform heat distribution, critical for the efficient drying of melamine-impregnated paper.
- High Efficiency: Despite high-speed operation, the system maintains low energy consumption and minimal waste, ensuring cost-effective production.
- Synchronization Unit: Ensures precise coordination of the production process, minimizing defects and enhancing overall quality.
- Extra Half-Bridge Conveyor: Offers additional support and stability during the transfer process, reducing the risk of paper jams or misalignments.
Highlights in the 3+5 (8-Oven) Melamine Impregnation Line Design
Thick plate frame for steady impregnation unit, with high glossy chromed metering rollers, long time and easier resin add-on device.
Main Features
Printed paper has a thorough impregnation in resin bath; resin add-on is gauged by the gap between two metering rollers; the roller gap is automatically adjusted by screw motor device.
Scope
- Built-in thick steel plate structure, sturdy and stable, keeps metering roller gap tolerance after adjustment.
- S-roller tractor unit with three chrome-galvanized rollers driven by VVVF control to match unwinder speed and reduce paper breakage.
- Back-coating device with three chrome-galvanized rollers; one for back coating and two for angular adjustment during paper guidance.
- Electrical sky-roller device with one breathing roller and one banana roller; provides additional paper path length to improve resin impregnation.
- Doctor roller device with hard-chrome glossy rollers and adjustable gap control for precision resin add-on.
- Germany Baumer proximity sensor feedback control for automatic digital doctor-roller gap adjustment.
- Resin scrapers at both ends of metering rollers to trim excess resin residue.
- Smoothing roller device with VVVF control to stabilize surface resin quantity.
- Resin bath device with full stainless inter-layered structure, movable lift, and integrated temperature control for stable operation and easy maintenance.
