1. Definition
Engineered Wood Panels are composite board products manufactured from wood or non-wood plant fibers through processes including mechanical separation, drying, adhesive application, forming, and hot pressing.
Core Advantages:
- Substitute solid wood, alleviating timber resource scarcity
- Large dimensions, uniform structure, minimal deformation
- Functional enhancements possible (flame-retardant/moisture-resistant/antibacterial)
2. Primary Types of Engineered Wood Panels
2.1 Classification by Raw Material & Process
Type | Raw Material | Structural Feature | Density (kg/m³) |
Plywood | Rotary-cut veneers | Odd-numbered cross-laminated layers | 450-650 |
Fiberboard | Wood fibers (refined to pulp) | Homogeneous, non-layered | Hardboard >800 |
MDF 600-800 | |||
Softboard <450 | |||
Particleboard | Wood flakes/chips | Fine surface + coarse core particles | 550-750 |
OSB | Strands (length-width ratio >3) | Surface strands longitudinally oriented + Cross-oriented core | 600-680 |
Blockboard | Solid wood strips + veneer faces | "Sandwich" core structure | 450-550 |
2.2 Functional Classification
Structural Panels (e.g., OSB compliant with ASTM D1037)
Decorative Substrates (e.g., MDF for PVC/wood veneer overlays)
Specialty Panels: Flame-retardant (oxygen index >30%), Moisture-resistant (thickness swelling <10%)

1. System Definition and Necessity
The Fully Automatic Steel Belt Steering System is a core subsystem of continuous presses, designed to monitor in real-time and dynamically correct lateral deviations of steel belts during operation, ensuring the belt remains within ±0.5mm of the press centerline.
Consequences of Steering Failure:
Belt edge wear → ↑ Risk of fracture
Mat edge collapse → ↑ Rejection rate by 50%
Platen scraping → ↑ Equipment repair costs by 30%
2. Core System Components
Component | Function | Technical Parameters |
High-Precision Displacement Sensors | Real-time detection of belt edge position (sampling every 200ms) | Accuracy: ±0.1mm |
Hydraulic Servo Steering Roller | Micro-adjusts belt path laterally (±30mm stroke) | Thrust: 5-10 tons; Response time <0.5s |
PLC Intelligent Controller | Executes steering algorithm (PID + feedforward control), outputs hydraulic valve signals | Processing cycle: 10ms |
Laser Alignment Gauge | Calibrates press centerline baseline (installed at infeed) | Calibration accuracy: ±0.05mm |

3. Steering Working Principle
3.1 Closed-Loop Control Flow
Step 1: High-precision displacement sensors detect the steel belt edge deviation (denoted as Δx) in real-time at 5Hz frequency (sampled every 200ms).
Step 2: The PLC controller processes Δx data and calculates the correction Δy via PID algorithm:
Δy=KpΔx+Kd⋅d(Δx)/dt
(Kp: Proportional gain; Kd: Derivative gain; d(Δx)/dt: Rate of deviation change)
Step 3: PLC outputs control signals to the hydraulic servo system, driving the steering roller to move laterally by Δy (positioning accuracy ±0.1mm).
Step 4: The steering roller pushes the belt back to the centerline (target accuracy ±0.5mm).
Step 5: Sensors re-detect deviation, initiating the next cycle (dynamic response time <0.5 seconds).
3.2 Dynamic Compensation Strategies
- Speed Feedforward Compensation: Predicts inertial belt drift during line acceleration (e.g., V↑10% → pre-tilt roller 2°)
- Thermal Deformation Compensation: Auto-corrects expansion offsets based on thermal gradient (inlet 230℃ → outlet 180℃)
- Load Adaption: Adjusts steering sensitivity during width changes (e.g., 1220mm → 2440mm)
4. Technical Advantages
Manual Steering | Auto Steering System | Benefits |
±5mm | ±0.5mm | 3×longer belt lifespan |
>5s | <0.5s | 90% reduction in mat collapse |
2 times/shift | Zero | Annual labor savings: ¥150,000 |
Variation >15% | Variation <5% | Qualification rate: 99.5% |
