1. Heavy-Duty Base & Bed: Provides an extremely solid foundation to withstand torsional forces and vibrations during peeling, ensuring long-term processing accuracy.
2. Spindleless Drive Assembly:
Main Drive Friction Rollers: A pair of heavy-duty steel rollers covered with a high-friction coating (e.g., polyurethane). They are the core power components for driving the log.
Hydraulic Pressure System: Provides adjustable, substantial clamping pressure to the drive rollers, ensuring effective driving without slippage even for irregular small-diameter logs.
V-Type Support & Adjustment Mechanism: Located below the drive rollers, it is used for initial log support and alignment. In some models, it can move up/down to adapt to diameter changes.
3. Precision Knife Carriage System:
Knife Holder & Peeling Blade: A knife holder that mounts a high-strength alloy peeling blade. The installation angle can be adjusted based on wood species.
Nose Bar Mechanism: Located just ahead of the blade edge, it is crucial. It compresses the wood fibers, creating compressive stress before cutting, thereby reducing checks on the veneer backside and improving quality.
Feed Drive System: Typically driven by a servo motor or hydraulic motor coupled with a precision ball screw, it controls the linear feed motion of the knife carriage, determining veneer thickness.
4. Automatic Centering & Measuring System: Located at the infeed end, it integrates sensors and actuators. This system is key to achieving high utilization rates from small logs, ensuring each log starts peeling from its optimal position.
5. Veneer Output & Handling Devices: Include lead-in rollers, conveyor belts, a hydraulic guillotine or flying cut-off saw, and optional automatic winder or pneumatic/mechanical stacker.
6. Advanced Electrical Control System:
PLC (Programmable Logic Controller): The brain of the equipment, handling all logic control, calculations, and coordination.
HMI (Human-Machine Interface Touchscreen): Used for parameter setting (thickness, length, speed, etc.), real-time monitoring, and equipment diagnostics.
Frequency Converters & Servo Drives: Precisely control the drive motors and feed motors.
7. Hydraulic Power Unit: Provides stable and reliable hydraulic power for actions such as centering, clamping, and rapid advance/retreat of the knife carriage.
Suitable Raw Material Wood
This machine is specifically designed for small-diameter timber, fast-growing species, and forestry residues. It is particularly suitable for peeling veneer from the following types of wood:
1. Softwoods (Conifers):
Pine: Such as Masson Pine, Scotch Pine, Radiata Pine, etc. This is the most typical suitable raw material. Relatively soft and easy to peel; resin content requires optimized tool management. Small-diameter pine logs and thinnings are ideal feedstock.
Cedar / Fir: Light and soft, straight grain, good peeling properties. Veneer is often used for construction plywood core.
Spruce: Properties similar to pine, a quality veneer material.

2. Soft Hardwoods (Fast-Growing Hardwoods):
Poplar / Aspen: Fast-growing, uniform, light, and soft texture. Easy to peel with a smooth veneer surface. An important raw material for plywood core and packaging board manufacturing. Very well-suited for small-log processing.
Eucalyptus: Fast-growing species, some varieties have moderate density. Suitable for peeling, but process adjustments may be needed due to growth stress. Small-diameter eucalyptus is a significant feedstock source.
Basswood / Linden: Very soft, easy to cut, used for high-grade decorative veneer.

3. Other Suitable Materials:
Birch (Some varieties): Although birch is generally harder, small-diameter logs or softer species can still be processed.
Reclaimed Timber: Old timber, demolition wood, etc., that is regular in shape and can be clamped securely.
Bamboo: Bamboo culms, with proper pre-treatment and clamping, can also be attempted for peeling.

The wood diameter should fall within the machine's clamping capability (e.g., Φ80mm - Φ400mm). Wood with low to medium density and relatively low cutting resistance is ideal. The machine's powerful adaptive clamping system can effectively handle common defects in such wood, like bending, ovality, and knots, transforming them into valuable products.
Optimized Design for Small-Diameter Logs
Exceptionally High Yield: The spindleless design minimizes core loss from small logs, improving wood utilization by an average of 15%-30% compared to traditional spindle-type equipment.
Fast Return on Investment: Effectively transforms low-value small-diameter logs and forest residues into high-value veneer, broadening raw material sources and reducing procurement and production costs.
Strong Adaptability: Particularly adept at handling small logs with a wide range of diameters and irregular shapes. It has low requirements for raw material, allowing for more flexible production scheduling.
Automation & Ease of Use: Features fully automated control from automatic feeding/centering to veneer output. Operators only need to set simple parameters, greatly reducing dependence on highly skilled workers.
Primarily used for peeling small-diameter logs, thinnings of species like pine, poplar, and eucalyptus into veneer for manufacturing plywood core/back layers, construction concrete formwork, or packaging boards. It is core equipment for enhancing the value of forestry residues and achieving efficient resource utilization.
