Multi-opening Hot Press Features
1. Core Structural Design
Lamination System:
5–30 precision-heated platens (standard size 2500×1300mm), each made of deep-drilled solid steel plate (thickness ≥60mm) with hard chrome plating (0.05–0.1mm) for anti-sticking.
Hydraulic Drive:
Bottom-mounted multi-cylinder synchronous system (0–120T adjustable pressure), using proportional flow valves to limit layer closing time error to ≤0.5 seconds (prevents glue pre-cure).
Heating System:
Electric Type: Embedded resistance wires (48kW power), zoned PID control (100–160°C±1°C);
Thermal Oil Type: Oil circulation (inlet temp ≥180°C), 30% higher thermal efficiency.
2. Operating Process
2.1 Rapid Closing:
Glued veneer stacks enter the press; hydraulic cylinders close all layers in 3–4 seconds, applying 0.6MPa initial pressure.
2.2 Segmented Pressing:
Pressure Rise: Reach target pressure (1.2–1.6MPa) within 15 seconds;
Holding Stage: 3-stage pressure drop (e.g., 1.6MPa→1.0MPa→0.8MPa), total duration 3–15 minutes (thickness-dependent);
Temperature Control: Continuous heating with ≤2°C surface variation.
2.3 Depressurization & Opening:
Stepwise pressure release (prevents delamination), automatic platen separation, finished panels transferred to cooling.
3. Adjustable Thickness Technology
3.1 Elastic Thickness Gauge:
Spring-roller modules on both sides of each platen compensate for veneer thickness tolerance (±0.3mm) by adjusting preload (range 2.5–40mm).
3.2 Screw Lift Positioning:
Stepper motors drive precision screws (±0.05mm accuracy) to set platen spacing. Input target thickness (e.g., 18mm) via HMI for auto-calibration.
4. Intelligent Control System
4.1 HMI Interface:
10-inch touchscreen for pressure/temperature/time settings, real-time monitoring (pressure curves, thermal maps).
4.2 Safety Protections:
Pressure overload relief (130% safety valve);
Hydraulic lock during power/oil failure;
Audio-visual alarms for temperature faults.
5. Performance Specifications
Compatible Panels: Plywood, LVL, formwork (density ≥0.65g/cm³);
Output Efficiency: 12 panels per cycle for a 12-opening press (cycle time 8–20 mins);
Energy Consumption: Electric ≈58kWh/ton, Thermal oil ≈42kWh/ton;
Thickness Tolerance: ≤±0.1mm across full panel (ISO 2426).
6.Technical Advantages
Simultaneous Closing Patent: <5% density variation;
Quick Changeover: Switch thickness settings in 5 minutes (vs. 30 mins conventional);
Modular Design: Post-installation layer upgrades (e.g., 12 to 20 openings).
Adjustable Thickness System
Technology:
Screw-lifting Thickness Gauge: Adjusts platen spacing (±0.05mm) via stepper motors.
Elastic Compensation: Springs and rollers adapt to veneer thickness variations (e.g., 18mm/28mm).
Operation:
1. Set target thickness (e.g., 18mm) → Control system drives screw lifts;
2. Positioning plates rise to calibrated height (scale visible);
3. Elastic units absorb fluctuations during pressing.
