Numerical control non-fastening-shaft rotating cutter and special transducer thereof and feed automatic speed regulation method

Abstract

The invention provides a numerical control no-card shaft rotary lathe, a special frequency converter and a feeding automatic speed regulation method, and relates to a wood processing machine and a special part and an application method used for the wood processing machine. The numerical control no-card rotary lathe of the invention also comprises a sensor which converts the position point of a workbench into an electric signal; the frequency converter is a special frequency converter which also comprises a first relation memory unit, a wood diameter operation unit, a second relation memory unit and a motor rotation speed operation unit; the first relation memory unit memorizes the corresponding relation between the position of the workbench and the diameter of the wood; the second relation memory unit memorizes the corresponding relation between the diameter of the wood and the rotation speed of a propulsion motor under different single plate thickness. The wood processing machine and the special part and the application method used for the wood processing machine save a plurality of stroke switches necessarily arranged by the existing automatic control system, especially lead the works completed by computer and PLC to be completed directly by the special frequency converter, greatly reduce the equipment cost, lead the operation of the equipment to be simple and convenient at the same time, and are beneficial for the market generalization.

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. Thus, the wood is driven to rotate, and the workbench drives the extruding friction roller 1 and the blade to continuously advance towards the direction of the wood to complete 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 co...
