Problems solved by technology

[0003] Due to the influence of ambient temperature, humidity and other factors, wood will expand with heat and contract with cold due to environmental factors. Therefore, at low temperature, the core board of the composite door panel is easy to shrink, resulting in its four sides showing white

Embodiment

[0028] Embodiment: A manufacturing process of a combined door panel, which is mainly divided into three processes. One is the production of the base plate. Before the production, the raw material plate with cracks is removed, and the raw material plate with a smooth surface and no cracks is loaded into a drying kiln. Spray steaming and heat drying, the time of spray steaming is 13 minutes, and the time of heating and drying is 20 days, so that the moisture content of the dried board is 15-20%, and the substrate is obtained; the specific moisture content of the board after the first drying can be set to 18% .

[0029] Then, the substrate is planed by a planer to make the thickness of the substrate uniform, and then the substrate is sawed to the required size according to the process requirements, and the door edge and the door core board are formed. After the door edge and the door core board are formed, pass through the grinding Grinding with light machine to remove roughness ...

Abstract

The invention discloses a manufacturing process of a composite door panel, which comprises the following steps: S1, spraying and steaming the raw material panels and then baking them so that the moisture content of the wood is 15-20% to obtain a substrate; S2, mechanically planing the substrate, making the The thickness of the substrate is uniform; S3, cutting the substrate to form the door edge and the door core board; S4, sanding the surface of the door core board and the door edge; S5, combining the door core board and the door edge into a door panel; S6, The door panel is dried twice, so that the moisture content of the wood is not greater than 10%; S7, spray paint on the surface of the door panel, and then ventilate and dry; S8, inspect the package. The manufacturing process of the combined door panel of the invention can effectively reduce the whitening of the edge caused by the shrinkage of the core panel, and improve the decoration of the door panel.

Description

technical field [0001] The invention relates to the technical field of wooden door processing, in particular to a manufacturing process of a composite door panel. Background technique [0002] At present, the combined door panels on the market are all spray-painted as a whole, that is, after the overall production of the door panel is completed, the entire door panel is spray-painted. Under this method, the paint only covers the visible surface of the door panel. [0003] Due to the influence of ambient temperature, humidity and other factors, wood will expand with heat and contract with cold due to environmental factors. Therefore, at low temperatures, the core board of the composite door panel is easy to shrink, causing its four sides to be white. Contents of the invention [0004] The purpose of the present invention is to provide a combined door panel manufacturing process, which can effectively reduce the occurrence of edge whitening caused by the shrinkage of the cor...
