A complete plywood production system is a complex integrated system, primarily composed of the following equipment:
1. Raw Material Processing Equipment
Debarker:
Used to remove bark from logs. Bark not only contains impurities like sand that can wear down tools, but its chemical composition can also affect bonding quality. The debarker efficiently separates bark from the wood using rotating cutters inside a drum or high-pressure water jets.
Bucking Saw / Log Saw:
Cuts long logs into specific-length segments based on process requirements and target product dimensions. Precise length control is crucial for peeling continuous, intact veneer in the subsequent step
2. Veneer Preparation Equipment
Veneer Peeling Lathe:
This is one of the core machines of the production line. The log segment (block) is clamped between two lathe centers and rotated at high speed. A sharp blade feeds radially into the spinning block, peeling it into a continuous, uniformly thin sheet of wood known as "veneer". Modern CNC peeling lathes can precisely control veneer thickness, producing high-quality veneer.
Veneer Conveyor:
Used to connect the peeling lathe to the dryer, transporting the wet veneer smoothly and continuously to the next process stage, preventing jams and breakage.
3. Veneer Drying & Processing Equipment
Veneer Dryer:
The moisture content of wet veneer after peeling is very high (typically >50%) and must be dried. Common types include roller dryers and mesh belt dryers. They use hot air (from steam, thermal oil, or gas) to forcibly reduce the veneer moisture content to the process range of 8%-12%, meeting gluing requirements and preventing mold.
Veneer Splicer and Patcher:
To improve raw material utilization, small dried veneer sheets or veneer with natural defects (like knot holes) need processing. The splicer joins small veneer sheets into large ones using glue threads or tape; the patcher fills holes with patches to create full sheets.
4. Gluing & Layup Equipment
Glue Mixer and Supply System:
Used for the preparation, mixing, and storage of adhesives (e.g., UF, PF, MUF, or formaldehyde-free adhesives like MDI). This system ensures stable glue parameters like viscosity, solid content, and pH, and delivers the glue to the spreader via pumps and pipelines.
Glue Spreader:
Typically a four-roller or double-roller machine that applies adhesive evenly and quantitatively to both sides of the veneer. Precise control of the glue spread rate is key to ensuring bond strength and controlling costs.
Layup Line:
Assembles the glued core veneers and face veneers according to a preset number of piles and grain direction (usually with adjacent grains perpendicular) to form a "mat". Automated layup lines use robots and conveyors for efficient, precise assembly, ensuring a symmetrical and stable mat structure.
5. Pre-pressing & Hot Pressing Equipment
Pre-press:
Applies cold pressure to the assembled mat before it enters the hot press. This provides initial bonding between the veneer layers, expels air from the mat, and gives the mat initial strength for easier handling and loading into the hot press, preventing collapse during hot pressing.
Hot Press:
This is the "heart" of the entire production line and the most critical equipment. It provides high temperature and high pressure to rapidly cure the adhesive, firmly bonding the multiple veneer layers into a solid panel – plywood. The number of openings, daylight, heating method (steam or thermal oil), and control system of the hot press directly determine production efficiency and product quality.
6. Finishing & Processing Equipment
Cooling and Turning System:
Panels exiting the hot press are very hot and require immediate forced cooling (often with fans) to set the bond strength and prevent warping or twisting due to residual heat.
Sander:
Sands both surfaces of the panel to a consistent thickness, eliminating thickness deviation and surface defects, resulting in a smooth, flat surface. This provides a good substrate for subsequent laminating, painting, or direct use. Common types include wide-belt sanders and heavy-duty sanders.
Edge Trim & Cross-Cut Saws:
Precisely cuts the large-format rough panels to the required final market dimensions (e.g., 1220x2440mm).
Stacker and Packaging System:
Automatically stacks the finished panels neatly and performs packaging operations like wrapping and strapping, facilitating storage and shipping.
7. Auxiliary Systems
Control System:
Modern production lines are controlled by a central PLC (Programmable Logic Controller) and HMI (Human-Machine Interface) touchscreen, enabling automated control of the entire line, process parameter setting, fault diagnosis, and production data recording.
Dust Collection System:
Used to collect the large amount of wood chips and dust generated during production (especially during peeling, sanding, and sawing), maintaining workshop cleanliness, protecting worker health, and meeting environmental standards.
1.Raw Material Pretreatment Section
Logs are debarked, steamed, and fed into a CNC peeling lathe.
Generated bark and wood chips are directly conveyed to the biomass energy system.
2.Veneer Processing Section
Wet veneer enters the high thermal insulation dryer, dried using hot air supplied by the waste heat recovery system.
Dried veneer is automatically graded via a visual inspection system.
3.Gluing & Layup Section
Qualified veneer enters the CNC glue spreader; MDI adhesive is applied precisely within a closed system.
Robotic layup system automatically assembles the mat according to preset structures.
4.Pressing & Curing Section
The mat enters the continuous press for continuous curing under constant temperature and pressure.
Steam generated during hot pressing is recycled via the waste heat recovery unit.
5.Finishing Section
Pressed panels are shaped through a forced cooling system before entering the CNC sanding line.
The dust collection system simultaneously captures processing dust, conveying it to the energy center.
6.Energy Monitoring Section
The EMS monitors energy consumption throughout the process, automatically adjusting equipment operating parameters.
Production data is uploaded in real-time to a cloud platform for energy efficiency analysis.
Outstanding Energy Saving & Consumption Reduction:
Comprehensive energy consumption reduced by over 25% compared to traditional lines.
Direct reduction of steam consumption by 30-50% through waste heat recovery and continuous pressing.
Precision gluing technology reduces adhesive consumption by 10-15%.
Top-Tier Environmental & Health Standards:
Specifically designed for producing No-Added-Formaldehyde (NAF) panels, with finished product formaldehyde emissions far exceeding ENF grade (≤0.025mg/m³) standards.
Extremely low dust and VOC emissions throughout the production process, creating a cleaner work environment and complying with international environmental regulations.
Excellent Product Quality & Economic Benefits:
Panels produced via continuous pressing have uniform density, stable structure, and extremely low warpage, suitable for high-end furniture and export markets.
The produced green, high-end panels command higher market premiums, significantly improving profit margins.
Lower energy and material consumption directly translate to reduced cost per panel.
Intelligence & Low Maintenance Costs:
High automation reduces reliance on labor and human error.
Intelligent early warning and diagnostic systems minimize unplanned downtime and maintenance costs.
