1. Main Frame: A rigid framework welded from channel steel or thick steel plates, serving as the base for all components.
2. Friction Drive System:
Main Driving Roller(s): Steel roller(s) with anti-slip patterns or coatings on the surface, serving as the primary power output component.
Pressure Rollers: Located above and on both sides of the driving roller(s), providing downward force to increase frictional grip. Typically controlled by hydraulic cylinders or screw mechanisms.
3. Tool Carriage & Feeding System:
Tool Carriage: The component that holds the peeling knife.
Peeling Knife: A long, specially made steel knife, a key consumable.
Feeding Mechanism: Economical models often use a manually adjusted leadscrew-nut mechanism or a simple variable-frequency motor driving a rack-and-pinion/leadscrew. It controls the feed rate of the tool carriage towards the log center, which directly determines the veneer thickness.
4. Power & Transmission System:
Main Motor: Drives the rotation of the main driving roller(s).
Gear Reducer: Reduces motor speed and increases output torque.
Hydraulic Power Unit (if hydraulic pressure rollers are used): A small hydraulic station supplying pressurized oil to the pressure rollers. Economical models may use simpler mechanical spring or screw pressure.
5. Control System: Very simple, typically consisting of an electrical control cabinet containing circuit breakers, contactors, push buttons, etc., for basic operations like starting/stopping the main motor and raising/lowering pressure rollers. No complex CNC system exists; thickness adjustment relies on manual scales or operator experience.
6. Auxiliary Parts: Infeed cradle, veneer discharge table, core chute, etc.
