Oven for fireboard production

Abstract

The invention discloses an oven for fireboard production. The oven comprises an oven body and a net belt transmission device, wherein the oven body comprises a pre-heating oven, a heating oven and a cooling forming oven which are sequentially arranged and comprise a plurality of wind chambers, respectively; wind ports at one side of the same wind chamber are positioned on a net belt, while the wind ports at the other side of the same wind chamber are positioned below the net belt; the wind ports at the same side of all chambers are alternatively distributed up and down on the net belt; wind inlet chambers are arranged at one side of each of the wind chambers of the pre-heating oven, and the heating oven or the cooling forming oven; and circulating wind chambers are arranged at the other side of each of the wind chambers of the pre-heating oven, and the heating oven or the cooling forming oven, respectively. With the adoption of the oven for the fireboard protection, a fireboard to be formed can be uniformly heated and cooled, thus, the coats of dual-component coat-core fibers can be uniformly melted and solidified; and the produced coconut fiberboards have high firmness, and the internal structures are uniform and consistent.

Description

technical field [0001] The invention relates to a device for producing fiberboard, in particular to an oven for producing fiberboard. Background technique [0002] Coconut palm fiber boards for mattresses in the prior art include upper, middle and lower layers, all of which contain two-component sheath-core fibers in the three layers, and use hot air penetration technology to melt the skin of the two-component sheath-core fibers in an oven. The melted hide is then solidified using cold air penetration technology, effectively laminating the three layers together. However, the ovens in the prior art can only use hot air penetration technology or cold air penetration technology to heat or cool the fiberboard from the top or bottom of the fiberboard when using the hot air penetration technology. In this way, the upper and lower layers of the fiberboard There is uneven heating and cooling, which leads to uneven melting and solidification of the sheath of the bicomponent sheath-c...

However, the ovens in the prior art can only use hot air penetration technology or cold air penetration technology to heat or cool the fiberboard from the top or bottom of the fiberboard when using the hot air penetration technology. In this way, the upper and lower layers of the fiberboard There is uneven heating and cooling, which leads to uneven melting and solidification of the sheath of the bicomponent sheath-core fiber, which affects the firmness of the fiberboard fiber, and the internal structure is uneven
