Problems solved by technology

For the composite door that has been laser-engraved, its disadvantage is that due to reasons such as control during laser engraving, the adhesive layer between the laminates of the composite door will be irradiated by laser light, which will vaporize part of the adhesive layer and form a vaporization cavity. Bubbles, resulting in weak connections between laminates of the composite door, causing the composite door to fall apart

Embodiment

[0013] Embodiment A laser engraved door panel is basically as attached figure 1 Shown: a laser-engraved door panel, including a wooden front panel 1, a rear panel 2, a left panel 3 and a right panel 4, the outer side of the front panel 1 is a carved surface, and the set laser-engraved part On the engraved surface, the inner surface of the front laminate 1 opposite to the laser engraved part is recessed to form a groove. The left panel 3, the front panel 1, and the rear panel 2 are all fixed by bolts (the bolts are not shown in the figure), and the gap between the front panel 1 and the rear panel 2 is filled with adhesive glue, which can be bonded at room temperature. The adhesive layer 6 is formed after the glue is cured.

[0014] The back laminate 2 is evenly distributed with glue supplementary holes on the corresponding area of ​​the laser engraving part, and a supplementary pipe 7 is inserted in the glue supplementary hole, and the pipe wall of the supplementary pipe 7 is ...

Abstract

This patent application belongs to the technical field of door panel processing. A laser-engraved door panel includes a front panel, a rear panel, and a solid adhesive layer between the front panel and the rear panel. The outer surface of the front panel is On the carved surface, both sides of the front and rear panels are fixed to the side panels by bolts, and a supplementary pipe with openings at both ends and hollow is embedded in the adhesive layer. The laser engraved parts are opposite, and the opening of the liquid outlet is blocked by a wax layer; the opening of the liquid inlet of the supplementary pipe is located on the rear layer. Compared with the traditional laser-engraved door panel, this patent application fills the vaporized cavity by setting the supplementary pipe to fill the adhesive glue, so as to prevent the loosening of the connection between the front layer and the rear layer caused by the vaporized cavity.

Description

technical field [0001] The invention belongs to the technical field of door panel processing. Background technique [0002] The solid wood door panel refers to the door panel material for making cabinets, wardrobes and other cabinets. Tenon, drilling, high-speed milling, assembly, grinding, painting and other processes are scientifically processed. Due to the high cost of solid wood door panels, various types of composite doors with low cost appear on the market. Composite doors are usually made of various composite materials to form laminates, and then the laminates are bonded to form an overall door panel structure. [0003] At present, no matter whether it is a solid wood door or a composite door panel, after the main body is manufactured, it needs to be decorated. The most common method is to engrave the door panel with a laser. For the composite door that has been laser-engraved, its disadvantage is that due to reasons such as control during laser engraving, the adhe...
