Description

CNC high speed cut saw Technical field

The present invention relates to wood processing machines, and more particularly to transverse cutting processing equipment for wood.

Background technique

With the increasing demand for wood resources for economic development and the protection and full utilization of limited log resources, the wood processing industry, especially the sawmill industry, is facing increasing economic and technical needs, while wood The horizontal cutting process is the most basic and important processing process in the sawing industry, which directly affects the discharge rate and wood utilization rate of wood sawing.

The current cutting method of wood is mainly subject to the operator's subjective knowledge of the wood use, wood length, and surface quality and defects of the wood to be cut off based on his own work experience and corresponding material requirements on the woodworking circular saw. After the judgment, the sawing position and the sawing length of the wood are artificially determined. There are many obvious deficiencies in the wood cutting and sorting according to the manual method. The first is that the truncation efficiency is low, there is more non-productive time, and the production efficiency is difficult to improve. Usually, the length of the cutoff of the finished wood is only about ten meters. The quality of the cut-off sorting is not high, the chance is too large, and the operator chooses And the determined sawing scheme is not only associated with operational experience, but also associated with high-intensity repeated fatigue work. Its truncated sawing scheme is often far removed from the optimal sawing scheme that people would expect.

Most of the woodworking circular saws used for the horizontal cutting of wood are still manually operated, which can not achieve continuous input and output of wood, can not achieve the continuous cutting process, and it is difficult to ensure the stability of sawing and sorting quality, production efficiency Low, unable to complete the automated, continuous production of the sawing process. Therefore, the traditional wood cutting method and cutting equipment limit the productivity of wood sawing and the increase of wood yield, resulting in great waste of wood resources and manpower.
