Device for forming multilayer fiberboard

Abstract

The invention provides a device for forming a multilayer fiberboard. The device comprises a first hot melting and blowing unit, a first fiber device, a second hot melting and blowing unit, a second fiber device and a belt-shaped moving device, wherein the moving device comprises a driving wheel at the front end, a driven wheel at the rear end and a driving belt wound on the driving wheel and driven wheel; the first hot melting and blowing unit and the first fiber device are arranged above the front part of the driving belt; and the second hot melting and blowing unit and the second fiber device are arranged above the rear part of the driving belt. The device has simple structure and smaller volume and simultaneously bonds multiple layers of fiberboards through a production line, thus improving the production efficiency and lowering the manufacturing cost.

Description

technical field [0001] The invention relates to the field of forming multilayer fiberboards, in particular to a multilayer fiberboard forming device capable of adjusting fiber composition at will. Background technique [0002] Fiberboard is usually a wood-based panel made by interweaving cellulose fibers and glued together. Adhesives and additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small difference in vertical and horizontal strength, and is not easy to crack. It has a wide range of uses. Generally speaking, it takes about 2.5 to 3 cubic meters of wood to manufacture 1 cubic meter of wood fiberboard, and the obtained wood fiberboard can replace 3 cubic meters of wood. Therefore, it can effectively save the required wood, and the development of fiberboard production is an effective way for the comprehensive utilization of wood resources. [0003] In addition, due to the gluing process of the fiberboard, it is ...

AI Technical Summary

Problems solved by technology

[0003] In addition, due to the gluing process of the fiberboard, it is easy to cause defects such as unequal surface areas on both sides, and warping and deformation of the board due to differences in expansion force after moisture absorption. In order to overcome these defects, wood is often used in the prior art. The fibers of the polymer are added to the fiber, so that the wood fiber board can combine the advantages of another fiber, for example, the surface of the wood fiber board is covered with a waterproof resin layer, so that the fiber board can achieve waterproof effect and avoid the warping of the board. The existing equipment is bulky and costly, which is not conducive to large-scale production
