Abstract

The invention discloses a flame retardant crop straw / wood composite board paving system and paving method. The system comprises an upper surface-layer forming screen, a core-layer forming screen, a lower surface-layer forming screen and a forming belt conveyor, the forming belt conveyor is located above the upper surface-layer forming screen and the lower surface-layer forming screen, the core-layer forming screen is located between the upper surface-layer forming screen and the lower surface-layer forming screen, a steel base plate is arranged on the forming belt conveyor, the tail end of the forming belt conveyor is close to an accelerating belt conveyor, an optoelectronic switch is arranged in the middle of the accelerating belt conveyor, and a spiral conveyor is arranged between the forming belt conveyor and the accelerating belt conveyor. Compared with the prior art, the system has the advantages of being good in surface smoothness, simple in treatment of plate decoration surfaces, low in machining cost, high in plate deformation resisting capacity, simple in paving process, small in occupied area, low in design and manufacturing cost and good in plate fire preventing performance.

Description

technical field [0001] The invention relates to the field of artificial board manufacturing, in particular to a flame-retardant crop straw / wood composite board paving system and a paving method. Background technique [0002] my country is rich in crop straw resources, but wood resources are in short supply. The main chemical composition of crop straw is similar to that of wood. It can be used as a raw material for wood-based panel production. It is of great significance to make full use of crop straw resources and replace wood resources to produce wood-based panels. However, compared with wood-based panels, crop straw-based panels are severely deformed and their development is limited. Combining crop straw and wood to produce wood-based panels can avoid the problem of deformation of wood-based panels made of crop straw alone, and can also alleviate the shortage of wood resources in my country. In addition, conventional paving methods are complicated, occupy a large area, an...
