I. Introduction

 

Peeling machine refers to the main equipment of the plywood manufacturer, which is used for the peeling of the remaining wood core of the card shaft peeling machine and the veneer of the small diameter wood after the rounding. The wood core with a diameter of not more than φ250mm can be peeled into veneers with different thicknesses of 0.5-3mm to improve the utilization rate of wood. It adopts advanced digital frequency conversion technology to control, so that its rotary cutting precision is similar to that of a rotary cutting machine with a card shaft. It has a knife door opening function, which is convenient for oil knife and easy to use.

2. Process requirements:

 

　　·Large starting torque, high requirements for low-frequency torque.

 

　　·The motor runs smoothly so that the cutting thickness of the wood chips is even.

 

　　·The motor requires high speed operation.

 

　　·Long-term work in humid and oily environment.

 

　　·The voltage fluctuation range is large.

 

3. System advantages:

 

　　1. ED3200 special frequency converter for rotary cutting machine adopts real current vector control technology, with 150% low-frequency starting torque output at 0.5HZ, ensuring that the motor has a strong cutting ability at low-speed cutting.

 

　　2, the frequency adjustment range of 0-500HZ can meet the normal operation of the equipment at high frequency. The encoder and displacement sensor automatically detect the diameter of the log, accurately calculate the feed speed of the tool bed, and cut the wood chips uniformly, high precision, and smooth surface. Greatly improve the quality of produced products.

 

　　3. Online adjustment of wood chip thickness process parameters, continuous adjustment of cutting thickness

 

　　4. Wide voltage application range, strict three-proof paint insulation technology. It fully meets the harsh working environment with large fluctuations in the equipment voltage range, humidity and oil pollution.
