Artificial board production line

Abstract

The invention discloses an artificial board production line and relates to the technical field of production of artificial boards. The artificial board production line comprises a first delivery partused for delivering a first material, a first spreading assembly and a second spreading assembly, wherein at least one pair of press roll assemblies are arranged at the tail end of the first deliverypart, the press roll assemblies are symmetrically arranged along the thickness direction of the first material, a steel belt is wound on the corresponding press roll assembly, an adhesive is mixed inthe first material, the adhesive is not mixed in a second material, the particle density of the second material is smaller than the particle density of the first material; the first spreading assemblyis arranged above the first delivery part and used for spreading the second material to the first material on the first delivery part; the second spreading assembly is arranged below the first delivery part and used for spreading the second material to the steel belt on the press roll assembly below. Compared with the prior art, for the artificial board production line provided by the invention,spraying of a releasing agent is not needed, and therefore, the production cost is saved, the overall structure of the production line is simpler, and the reliability is relatively high.

Description

technical field [0001] The invention relates to the technical field of wood-based panel production, in particular to a wood-based panel production line. Background technique [0002] At present, during the production and processing of wood-based panels, raw materials such as wood fibers or straw fibers mixed with glue need to be hot-pressed at high temperature by a press to form wood-based panels with a certain strength. In the pressing process, in order to facilitate demoulding, it is usually sprayed directly on the steel belt by the nozzle. [0003] The method that adopts release agent to carry out demoulding in the prior art mainly has two problems: (1) the price of release agent is more expensive, and the production of wood-based panels requires more release agents, so it increases the number of wood-based panels. (2) Spraying the release agent on the nozzle requires an additional set of systems, including preheating, stirring and heating of the release agent, and a con...

[0003] The method that adopts release agent to carry out demoulding in the prior art mainly has two problems: (1) the price of release agent is more expensive, and the production of wood-based panels requires more release agents, so it increases the number of wood-based panels. (2) Spraying the release agent on the nozzle requires an additional set of systems, including preheating, stirring and heating of the release agent, and a controller to control the spraying amount of the head. At the same time, the nozzle is easily blocked. The nozzle is clogged, and the wood-based panel formed by pressing is difficult to separate from the steel belt, causing serious losses
