Introduction to Double-Layer Roof Panel Forming Machine
I. Equipment Definition and Function**
The **Double-Layer Roof Panel Forming Machine** is an automated device designed to produce double-layer metal roof panels through roll-forming technology. It processes two layers of metal sheets (or a combination of metal and composite materials) simultaneously to create roof panels with air gaps, insulation layers, or reinforced structures. These panels are widely used in industrial buildings, warehouses, cold storage facilities, sports stadiums, and other large-scale constructions, offering **thermal insulation, soundproofing, wind resistance, and waterproofing** properties.
II. Core Working Principles
1. **Dual-Layer Synchronized Forming**
- **Independent Feeding for Upper and Lower Layers**: Two separate decoiling systems feed metal coils (e.g., color-coated steel, galvanized steel).
- **Composite Structure Design**: Some models support adding insulation materials (e.g., rock wool, polyurethane foam) between the layers, bonded via roll-forming to create "sandwich" panels.
- **Air Gap Formation**: Without filler materials, the machine controls the spacing between layers to form hollow sections for enhanced thermal performance.
2. **Forming and Joining Processes**
- **Roll Forming**: Both layers pass through multiple sets of rollers to gradually shape edges, interlocks, or corrugated profiles, ensuring airtight assembly.
- **Mechanical Interlocking or Welding**: Advanced models integrate edge-sealing via mechanical locks or high-frequency welding for structural integrity.
3. **Fully Automated Workflow**
Decoiling → Leveling → Preheating (if bonding) → Dual-layer roll forming → Filler injection (optional) → Lengthwise cutting → Stacking, all controlled by PLC.
