Method and tool for machining rod-shaped reconstructed wood unit

Abstract

The invention discloses a method and a tool for machining a rod-shaped reconstructed wood unit. The method comprises the following steps of: cutting wood along the longitudinal direction of the fiber of the wood according to the set depth by using a scratching knife with more than two blades without sawdust; generating lateral separation and generating a scratching knife mark by the wood tissue with the set depth; cutting along the longitudinal direction of the wood by using the scratching knife blade in the direction vertical to the depth of the scratching knife mark; and cutting the wood toform a wood-wool rod. The middle boss of the base of a cutter is provided with dovetail grooves; one side surface of each dovetail groove is provided with a rectangular path; a plane cutter is arranged in the dovetail groove on the side, and the scratching knife is installed in the dovetail groove on the other side; the scratching knife and the plane cutter are fixed on two sides of the dovetail groove by press cakes; the scratching knife and the plane cutter are higher than the top surface of the boss; and a gap is formed between the inclined bottom surface of each press cake and the blade of the plane cutter. The wood-wool rod is easy to realize directional pavement when a wood assembly is reconstructed. The wood is cut longitudinally along the vertical grain without sawdust. The tool has the advantages of small noise, small cutting resistance, no dust pollution and high processing efficiency.

Description

technical field [0001] The invention relates to a processing method and cutting tool for a recombined wooden unit, in particular to a processing method and a cutting tool for a rod-shaped recombined wooden unit. Background technique [0002] The manufacturing units of recombined wood products such as traditional wood-based panels include wood powder, wood fiber, shavings, and veneer, which are used to manufacture various recombined wood products such as particleboard, fiberboard, plywood, laminated wood, and technological wood, and form a long industrial chain. , Large-scale industrial groups have made due contributions to the development of the national economy, the efficient use of wood resources, and the protection of forests and the ecological environment. The processing technology for manufacturing these units mainly uses various pulverizers, chippers, heat grinders, rotary cutters and other machinery. However, wood powder, wood fiber, shavings and other units have dis...

Problems solved by technology

However, wood powder, wood fiber, shavings and other units have disadvantages such as high processing energy consumption, large dust and noise, easy to cause work environment pollution, and large amount of glue. According to the parallel orientation of the wood fiber direction, the gluing is efficiently formed, resulting in unsatisfactory gluing strength
