2. Steel belt and hot press plate system
- Segmented heating hot press plate: 8~12 temperature control zones (200~240℃), independent temperature adjustment to meet the curing requirements of different thicknesses.
- High-strength steel belt: tensile strength >1200MPa, surface hardness HRC 55~60, ensuring the transmission stability of 80mm thick plates.
3. Thickness control system
- Laser thickness gauge: online scanning thickness accuracy ±0.03mm (traditional mechanical ±0.1mm).
- Hydraulic synchronous cylinder group: 30~50 cylinders on each side, independently controlling the opening and closing degree of the pressure plate (resolution 0.01mm).
1. Dynamic pressure compensation technology
- When the low density area of slab is detected, the local pressure is instantly increased by 5~8MPa (traditional presses can only adjust the pressure globally).
- Case: When producing 18mm OSB, the lateral density difference is reduced from ±8% to ±3%.
2. Adaptive thickness control
3. Energy saving and consumption reduction
- 25%~30% energy saving compared to proportional valve hydraulic system:
- Energy is only supplied to the cylinder that needs to be pressurized (traditional system maintains pressure throughout the process)
- Energy recovery during the pressure reduction stage (accumulator stores ≥15% hydraulic energy)
1. Required Configuration
- Number of Cylinders ≥40/side (80mm plate requires support density)
- Servo Valve Frequency Response ≥100Hz (required for thin plate production)
- Zone Temperature Control ≥10 Zones (solve the problem of core layer solidification of thick plates)
2. Economic Considerations
- When the production thickness is <25mm, a simplified version (30 cylinders/side) can be selected
- 80mm ultra-thick plate production line requires enhanced frame design (bending stiffness >5×10⁶ Nm/rad)
Continuous Flat Press is a key equipment in woodworking machinery used in the production of man-made boards (such as particleboard, fiberboard, oriented strand board, etc.). It uses a continuous hot pressing process to press the slabs mixed with wood fibers or scraps and adhesives into high-strength, high-density boards.
Working Principle
The core of the continuous flat hot press is to continuously press the slab through high temperature and high pressure. Its working process is as follows:
1.Feeding: The slab after paving and forming is sent to the entrance of the hot press through a conveyor belt.
2.Preheating and pre-pressing: Before the slab enters the main pressing area, the adhesive is softened by a preheating device and the air is expelled by pre-pressing.
3.Main pressing: The slab enters the pressing area composed of multiple layers of hot pressing plates, and is continuously pressed under high temperature (usually 180-250℃) and high pressure (2-5 MPa) to solidify the adhesive and tightly combine the fibers.
4.Cooling and board discharge: The pressed board is cooled and shaped in the cooling section, and then cut into standard sizes.
Technical advantages
Continuous production: Compared with intermittent presses (such as multi-layer hot presses), production efficiency is greatly improved.
Stable quality: pressure and temperature are evenly distributed, the density of the board is highly consistent, the internal stress is small, and it is not easy to deform.
Energy saving and environmental protection: high thermal energy utilization rate, sufficient curing of adhesives, and reduced formaldehyde release.
Flexibility: The pressure curve can be adjusted to adapt to the production of boards of different thicknesses and densities.
