Manufacturing method and production line of composite panels

Abstract

The invention belongs to the technical field of wood panel production and discloses a production line of composite panels. The production line comprises a lower surface layer paving working position,a first prepressing working position, a bonding working position, an upper surface layer paving working position, a second prepressing working position and a hot pressing working position, and furthercomprises a conveying device. The lower surface layer paving working position, the first prepressing working position, the bonding working position, the upper surface layer paving working position, the second prepressing working position and the hot pressing working position are sequentially arranged. The conveying device is used for conveying materials to each working position. The bonding working position is provided with two material inlets, wherein one material inlet of the bonding working position is connected with a material outlet of the first prepressing working position, and the other material inlet is provided with a glue applying working position. A manufacturing method comprises the following steps of: manufacturing raw materials for surface layers, gluing plywood, manufacturing the lower surface layer, bonding the lower surface layer, manufacturing the upper surface layer, hot pressing and stacking. The manufacturing method enables the production efficiency to be high through a specially designed one-time hot pressing molding, reciprocating plate feeding and paving process, and enables a plywood layer and the surface layers to be more tightly combined and protected against easy degumming and cracking.

Description

technical field [0001] The invention belongs to the technical field of wood board production, and in particular relates to a manufacturing method and a production line of a composite board. Background technique [0002] Wood is widely used in architectural decoration, furniture and home decoration, and is closely related to our daily life. The commonly used wooden boards are logs, plywood and particle board. [0003] Logs are sturdy and durable, with natural texture, most of which have the unique aroma of natural wood, good hygroscopicity and air permeability, which are beneficial to human health and do not cause environmental pollution. They are high-quality boards for making high-end furniture and decorating houses. However, the cost of log boards is high, the construction technology requirements are high, and it will greatly consume forest resources. [0004] Plywood is made by sticking three layers of thin wood together in different grain directions. Plywood can not on...
