Abstract

The present invention is numerically controlled no-clamper rotary trunk-layer stripping machine and its special frequency converter and automatic feeding speed regulating method, and relates to timber working machine. The numerically controlled no-clamper rotary trunk-layer stripping machine has worktable, displacement sensor and special frequency converter, which comprises the first memory unit, one timbre diameter calculating unit, the second memory unit and one motor rotation speed calculating unit. The numerically controlled no-clamper rotary trunk-layer stripping machine with special frequency converter to replace computer and PLC controller has simple structure, low cost, simple operation and high marketability.

Description

technical field [0001] The invention relates to a wood processing machine, in particular to a shaft-free rotary cutter for cutting logs into continuous thin plates. Background technique [0002] In the existing card-free rotary cutting machine, the power of the motor drives the three friction rollers clamping the log through the mechanical transmission mechanism, that is, the extrusion friction roller 1, the upper main friction roller 2, and the lower main friction roller 3 to rotate. Thereby, the wood is driven to rotate, and the workbench drives the extruding friction roller 1 and the blade to advance continuously towards the direction of the wood, completing the process of rotary cutting the veneer of the wood. During the rotary cutting process, the diameter of the wood is getting smaller and the rotation speed is constantly accelerating, so the speed of the workbench is required to be continuously accelerated to make the thickness of the veneer produced by the rotary cut...
