 | I. Significance of the Width Range (2600-2700mm) |
This specific width range is not arbitrary; it is the result of a precise balance between market demand, production efficiency, and cost-effectiveness.
Market Adaptability: This width range is specifically optimized for the efficient production of the world's most universal panel size—1220mm x 2440mm (4 feet x 8 feet). A raw board produced by a 2700mm wide press can easily be ripped down the middle into two slabs slightly wider than 1220mm, which, after precise trimming, yield standard-sized finished panels. This "rip-in-two" cutting scheme offers extremely high material utilization with minimal waste.
Production Efficiency & Flexibility: Compared to narrower presses, this width produces more board area in a single pass, significantly increasing production line capacity. It also provides sufficient flexibility for producing other non-standard sizes (e.g., large countertops) without investing in more expensive and energy-intensive wider presses.
Technical Economy: This width falls into the "medium-wide" category, striking an optimal balance between equipment manufacturing cost, energy consumption, factory space requirements, and final output. It meets the demands of large-scale production while avoiding the enormous investment and operational costs associated with ultra-wide presses.
| Workflow of the continuous press machine |
The workflow of a continuous flat press is a precise, dynamic hot-pressing process. Once the pre-pressed mat enters the press, the following sequence begins:
1. Mat Feeding and Nipping:
The pre-pressed, self-supporting continuous mat is precisely fed into the inlet of the continuous flat press by a conveyor.
At the inlet, two enormous endless steel belts gently but firmly nip the mat. A specially designed inlet nose ensures a smooth transition, preventing damage to the mat surface.
2. Heating and Pressure Application:
The steel belts, carrying the mat, enter the main pressing zone. The mat travels between a series of heating platens, guided by the belts.
The Heating Platens provide high temperatures (typically 180-220°C), which are conducted through the steel belts to the mat, activating the resin binder.
Simultaneously, the Hydraulic System drives the platens to exert immense, precisely zoned pressure on the belts (and the enclosed mat). This pressure is not constant but is programmed according to the recipe across different press zones (e.g., inlet zone, main press zone, calibration zone).
3. Plasticization and Curing:
Under the combined action of "heat, pressure, and time," the wood fibers in the mat plasticize, and the resin rapidly cures from liquid to solid, firmly bonding the fibers together.
The density of the mat increases drastically, and its thickness is compressed to the preset target value.
4. Precision Thickness Control:
Throughout the pressing process, the Thickness Control System operates continuously. By monitoring the board thickness at the exit in real-time, it provides feedback to the control unit, which then commands the Thickness Adjustment Mechanisms (e.g., eccentric shafts) inside the press to make dynamic, micrometer-level adjustments to the platen gap, ensuring thickness uniformity.
5. Board Discharge:
Upon exiting the press, the mat, having completed the hot-pressing and curing process, is transformed into a solid, dense, continuous fiberboard.
The steel belts separate from the board at the outlet and return to the press inlet via the bottom roller system to begin a new cycle. The cured fiberboard is then transported to subsequent cooling and cutting stages.
| Core Components |
The continuous flat press is a complex mechatronic-hydraulic system. Its core components include:
1. Main Frame:
Typically a box-type structure welded from high-quality steel plates, serving as the "skeleton" of the press. It must possess extremely high strength and rigidity to withstand pressing forces of thousands of tons without deformation.
2. Steel Belt System:
Endless Steel Belts: Two massive (tens of meters long), high-precision, heat-resistant, fatigue-resistant special alloy steel belts. They are in direct contact with the mat, serving the triple purpose of transmitting pressure, conveying the mat, and transferring heat.
Drive Roller and Tension Roller: The Drive Roller (usually at the outlet) provides the motive power for the continuous movement of the belts. The Tension Roller (usually at the inlet) provides constant tension to the belts via hydraulic or mechanical means to prevent slipping and misalignment.
3. Heating Platen System:
Comprises multiple large cast iron or steel plates with internal passages for circulating thermal oil or high-pressure steam as the heat transfer medium.
The platens are precisely mounted on the main frame, forming upper and lower sections. They are controlled and heated in zones to create the required temperature profile.
4. Hydraulic System:
Acts as the "muscles" of the press. It includes the hydraulic power unit, cylinders, control valves, and piping.
It provides the force for opening and closing the main press and enables precise, independent control of pressure in different zones according to the process curve.
5. Roller Carpet System:
Located between the steel belts and the heating platens, it consists of thousands of densely arranged, small-diameter rollers.
Core Functions:
Support the Belts: Prevent excessive deflection of the steel belts under high pressure.
Reduce Friction: Transform the sliding friction between the steel belts and the stationary heating platens into rolling friction, significantly reducing drive power and belt wear.
Uniform Pressure and Heat Transfer: Ensure pressure is applied evenly to the mat and facilitate heat conduction.
6. Thickness Adjustment Device:
A key actuator for achieving high-precision thickness control. The most common type is the Eccentric Shaft Adjustment Mechanism.
It consists of a series of eccentric shafts installed at the ends of the support rollers. By precisely controlling the rotation angle of the eccentric shafts with servo motors, the support rollers can be raised or lowered, thereby indirectly and locally fine-tuning the gap between the upper and lower platens for dynamic thickness control.
7. Lubrication and Cleaning Systems:
Lubrication System: Automatically supplies lubricating oil to the bearings of moving parts like the roller carpet and chains, ensuring smooth operation and reducing wear.
Belt Cleaning System: Uses scrapers, wire brushes, or vacuum devices to continuously remove contaminants (resin, fibers) adhering to the steel belt surfaces, protecting the belts and ensuring panel surface quality.
8. Automation Control System:
Serves as the "brain" of the press. It typically consists of PLCs (Programmable Logic Controllers) and an industrial PC (Supervisory Computer).
It monitors and regulates all key parameters—pressure, temperature, speed, tension, thickness—in real-time, ensuring process stability, high efficiency, and consistent product quality.
