Description

Timber cutting machine

Technical Field

The invention relates to the technical field of timber processing auxiliary equipment, in particular to a timber cutting machine.

Background

Wood is a lignified tissue formed by plants capable of secondary growth, such as trees and shrubs. After the primary growth of these plants is completed, the vascular layer in the rootstocks starts to move, developing phloem outward and wood inward. Wood is a generic term for the development of plant tissue inward of the vascular cambium, including xylem and parenchymal rays. Wood plays a great supporting role in human life. Wood is used in different ways according to its different properties.

The wood is a traditional building material and is widely applied to ancient buildings and modern buildings. Structurally, wood is mainly used in frames and roofs, such as beams, columns, rafters, roof trusses, brackets, etc. Many buildings in China are of wood structures, have high level in building technology and art, and have unique style. Before the wood is used, the wood is generally required to be processed.

Wood processing refers to processing that is performed mainly by mechanical or chemical methods using wood as a raw material. The wood processing technology comprises basic processing technologies such as wood cutting, wood drying, wood gluing and wood surface decoration, and functional processing technologies such as wood protection and wood modification. Cutting includes sawing, planing, milling, drilling, sanding, and the like. The method of cutting differs from other materials due to the effects of wood texture, grain, etc. The moisture content of wood also affects the cutting process, for example, the veneer making method and wood chip production require wet material cutting, and most of the workpieces require dry material cutting. Drying is generally referred to exclusively as drying of the finished material.
