Description

Technical Field

[0001] The utility model relates to the field of wood-based panel processing, in particular to a chamfering device for wood-based panels used in numerical control machine tools. Background Technique

[0002] Wood boards, namely wood-based panels, are divided into solid wood boards and composite boards. As the name implies, solid wood boards are made of complete wood. These boards are strong, durable, and have natural textures, making them the top choice in decoration. However, due to the high cost of such boards and the high requirements for construction technology, they are not widely used in decoration. Solid wood boards are generally classified according to the actual name of the board, without a unified standard specification. Composite wood floors, also called laminate floors, often have their own names given by some enterprises for different purposes, such as super strong wood floors, diamond-shaped wood floors, etc. No matter how complex or different their names are, these boards belong to composite floors. The disadvantage of composite floors is that when laying a large area, there will be a phenomenon of overall arching and deformation. Since they are composite, the edges and corners between the boards are prone to breakage or wear.

[0003] However, during the assembly and practical use of wood-based panels, for safety or aesthetic reasons, chamfering processing needs to be carried out on the wood boards. Traditional wood board chamfering equipment, such as the technical solution to be disclosed in the patent with the application number CN202122777886.9 and the invention name of an automatic chamfering device for wood boards of a laminator, has low efficiency and low flatness of the cutting plane.
