1.  Debarker:

      Function: Uses hydraulic drive or multi-head rotary design to efficiently remove bark, sand, and other impurities from logs, ensuring a smooth veneer surface and protecting the peeling blade.

      Features: Adapts to logs of different diameters, provides clean peeling with minimal wood damage.

2.  Log Buck Saw:

      Function: Saws debarked logs into precise lengths required by the veneer lathe (typically 2.6m or 2.85m).

      Features: High-power motor, precise cutting, minimal length error.

3.  Log Steaming Pond/Vat:

      Function: Softens log billets by heating with hot water or steam, breaking down the toughness of the wood fibers to facilitate the peeling of high-quality, crack-free thin veneer.

      Features: Energy-efficient insulation, controllable temperature, ensures even the core reaches the optimal temperature for peeling.

4.  Precision Veneer Lathe:

      Function: One of the core machines. Clamps the steamed billet and rotates it at high speed, while a sharp blade peels a continuous sheet of veneer at a predetermined thickness.

      Features: Optimized for thin veneer production, employs Constant Linear Speed Peeling and high-precision servo drives to ensure extremely consistent veneer thickness (tolerance ±0.05mm) and a smooth, splinter-free surface. This is the foundation for high-quality thin plywood.

5.  Mesh Belt / Roller Dryer:

      Function: Dries the green veneer (MC ~30-60%) after peeling to a suitable moisture content (8-12%).

      Features: Zoned control of temperature, humidity, and air speed prevents thin veneer from curling or cracking due to rapid drying. Heat recovery systems reduce energy consumption.

6.  Veneer Clipper:

      Function: Cuts the dried continuous veneer ribbon into sheets of specified width and length, automatically rejecting sections with major defects.

      Features: High clipping speed, photoelectric positioning, high cutting accuracy.

7.  Veneer Splicer:

      Function: Joins smaller veneer sheets (especially core veneer) into full-size sheets using glue thread, tape, or tapeless (pin-based) splicing.

      Features: Automated operation, creates strong and flat splices without scars, ensuring uniform panel strength and avoiding overlaps or gaps after pressing.

8.  Four-Roller Double-Sided Precision Glue Spreader:

      Function: Applies adhesive evenly to both sides of the veneer (typically core and center plies).

      Features: Core gluing equipment. Consists of a pick-up roller, application roller, and two precision doctor rolls. Precise adjustment of the nip allows accurate control of glue spread on each side (e.g., ±5g/m²), ensuring uniform application without transverse streaks or misses, significantly saving adhesive. Compatible with various low-viscosity eco-friendly glues.

9.  Automatic Lay-up Line:

      Function: Stacks the glued veneers with unglued face/back veneers according to the preset number of plies and grain direction (adjacent layers perpendicular) to form a mat.

      Features: Employs robotic arms or staggered assembly tables for full or semi-automatic lay-up, greatly improving efficiency, reducing labor, avoiding mismatches, and ensuring a symmetrical and stable mat structure.

10. Pre-press:

      Function: Applies medium-low pressure at room temperature to the assembled mat to achieve initial bonding and "green strength".

      Features: Prevents the mat from collapsing or shifting during transport to the hot press, reduces hot press loading time, improves hot pressing efficiency.

11. Multi-opening Hot Press:

      Function: The core equipment of the production line. Presses the pre-pressed mats under high temperature (typically 130-180°C) and high pressure (typically 5-20MPa) to rapidly cure the adhesive, forming a permanent bond.

      Features: For thin plywood production, uses step-wise pressure application/release and zonal temperature control (thermal oil heating provides more uniform temperature) with PLC program control. Ensures heat and pressure penetrate each veneer layer evenly while perfectly controlling final thickness tolerance and avoiding "soft edges" or "blisters".

12. Cooling Turner:

      Function: Uniformly cools the hot panels from the press and automatically turns them over to prevent warping due to uneven stress.

13. Cross-Cut & Edge Trimming Saw:

      Function: Trims all four rough edges of the panel to achieve precise length/width dimensions and square edges.

      Features: Dual saw group design (longitudinal first, then cross-cut), servo motor drive, precise positioning.

14. Sizing Sander:

      Function: Sands the top and bottom surfaces of the panel precisely to eliminate thickness deviation, the pre-cured layer, and surface defects, obtaining a smooth, flat surface and consistent final thickness.

      Features: Key equipment for thin panel production. Typically a 3 or 4-head combination (e.g., coarse, fine, finish). A high-rigidity frame, precise feed system, and adaptive pressure pads enable micron-level sanding of thin panels, eliminating washboarding and guaranteeing no sand-through.

15. Central Control System:

      Function: Based on industrial PLC and HMI/Industrial PC, integrates control of the entire production line.

      Features: Monitors equipment status and process parameters (temperature, pressure, speed, glue spread, etc.) in real-time. Enables data acquisition, fault alarm, recipe storage, and remote support, ensuring continuous, stable, and efficient production.

Ultimate Precision: Final product thickness tolerance can be controlled within ±0.1mm, meeting international high-end standards.

  High Automation: High degree of automation from veneer feeding to finished product sanding, significantly reducing labor costs and intensity.

  Energy Efficiency & Eco-Friendliness: Incorporates efficient drying technology, heat recovery systems, and low glue consumption design, complying with environmental standards.

  Flexible Adaptation: The production line can easily adapt to different wood species (poplar, eucalyptus, mixed hardwood, etc.) and thickness requirements (3mm, 6mm, 9mm, 12mm, 15mm, 18mm) through parameter adjustments.

  Intelligent Control: A central control room monitors the entire line, displays real-time production data, and provides automatic fault diagnosis and alarms, ensuring continuous and stable operation.
