V-arc-shaped shallow slot structure and its machining method for composite floor

Abstract

This is about a V shape arc shallow slot structure of composite floor and its manufacture method. A prototype of the board is processed through a miller along its perimeter a V shape arc of radius R=6~8 mm and depth h=0.3~1.2 mm. Then process a shallow slot along a tangent bevel with an angle to the board of alpha=11~37o at a depth h=0.8~1.5 mm. Finally pave on whole board surface including slot wear resistance paper and decoration paper and hot press by a thermo presser to form the final board product.

Description

technical field [0001] The invention relates to a floor and a processing method thereof, in particular to a V-shaped shallow groove structure of a composite floor and a processing method thereof. Background technique [0002] Composite flooring is based on wood fiber board, the surface is covered with wear-resistant layer (aluminum oxide) and simulated printed wood grain paper (decorative paper) layer, and the bottom is additionally balanced layer, which is compounded by high temperature and high pressure. It is a ground decoration material commonly used in public places. When this kind of floor is installed, it is mainly completed by the tongue and groove connection around the floor, as long as the floor is assembled directly. The joints formed by the joints between floors have always been a technical subject of research and improvement in the flooring industry. At present, there are three main types of seams for composite flooring: one is flat seams; the other is "V"-sha...

AI Technical Summary

Problems solved by technology

"Flat seam" means that the end face of the gap formed by the floor assembly is flush with the board surface. Due to the error of processing accuracy or the influence of thermal expansion and contraction, it is easy to produce height difference, and the solid wood feeling is not strong; "V" type seam is the upper groove and the lower seam. The purpose is to cover the seam with the groove to enhance the solid wood feeling of the floor, but the edge of the groove is angular and easy to wear; although the "U"-shaped seam is improved on the basis of the two seams, the slope produced after the rounded corner is too steep, It has the same defect as the "V" type seam, that is, the bottom of the groove formed when the floor is assembled is in the shape of an acute angle, which makes the groove narrow, easy to accumulate dirt, and is inconvenient to clean; and the base material of the groove edge is exposed, and the moisture resistance is poor
