A production process of hidden plastic edge wood floor

Abstract

The invention provides a production process for a wood floorboard with lower hidden type plastic edges. The production process comprises the steps that (10) plate cutting is conducted, that is, a plate is cut to form a solid wood floorboard blank according to a predetermined size; (20) double-layer T-shaped grooves are formed, that is, the double-layer T-shaped grooves are formed in the four sides of the solid wood floorboard blank to make the four sides of the solid wood floorboard blank retract inwards one by one from top to bottom to form three layers of steps, and the width of the uppermost step on each side is largest; (30) injection molding and edge sealing are conducted, that is, the solid wood floorboard blank is placed into a mold cavity of an injection molding and edge sealing machine, the plastic edges are formed on the double-layer T-shaped grooves through the injection molding and edge sealing machine, and the plastic edges are hidden on the reverse side of the uppermost step on each side. According to the production process, reasonable rabbets are designed in the four sides of the wood floorboard, edge sealing plastic can be hidden below the upper surface of the wood floorboard after injection molding and edge sealing are completed, and the plastic edges can not be seen through naked eyes after the wood floorboard is laid.

Description

technical field [0001] The invention relates to a production process of a wooden floor, in particular to a production process of a hidden plastic edge wooden floor. Background technique [0002] The assembly of traditional wood flooring is mainly to open grooves around and at the bottom of the floor through machinery, that is, to process it into a wooden tenon joint structure. This tenon joint structure needs to occupy about 5mm of wood, which is not only a waste of wood, but also difficult to process. The joint structure needs hard wood to meet the requirements, which hinders the development of the wooden floor industry. [0003] The tongue-and-groove formed by the mortise and tenon structure of traditional wooden floor is exposed, which is easy to cause formaldehyde release. The water from the floor repeatedly invades from the grooves around the floor, so the grooves around the floor absorb moisture and expand, making the floor surface easy to roll up and warp, reducing t...

Problems solved by technology

Because in this invention, the positioning rod 21 is controlled by the spring, so during the whole injection molding process, the positioning rod 21 has always been against the wooden substrate until the end of the injection molding, causing the position where the wooden substrate is supported to not be sealed by plastic to form a cavity, which will cause water. Particles or moisture can invade from the cavity and cause the waterproof performance of the wooden floor to decline, and harmful gases such as formaldehyde will be released from the cavity
