Problems solved by technology

The ribs of the above two products are thin, so the mold is very complicated, and the cross-sectional density distribution gradient of the product is large, and the density of the internal ribs is only about 0.2g/cm3, resulting in

Embodiment 1

[0033] Embodiment 1: one-time molding process

[0034] In conjunction with the accompanying drawings: the hot press of this embodiment is composed of several parts such as an upper platen 1, a stripper plate 2, a tip punch 3, and a lower platen 5. The cross-sectional shape of the punch 3 is various polygons, and the inside of the punch is hollow. The pointed end faces downwards, and the upper end of the punch is provided with an inner sleeve 8 for the hot oil inlet and an outer sleeve 9 for the hot oil outlet; a section of the front end of the punch in this embodiment is made of non-metallic material, so that when the punch is inserted In the slab, when the compression ratio of the slab is relatively small, the slab may not be heated, and only when the slab reaches a certain compression ratio, the slab is heated.

[0035] A series of channels for fixing the punch are drilled on the fixed punch and the upper pressing plate that pressurizes the slab. The inner casing is installe...

Abstract

The invention relates to a porous plant fiber plate, relative preparation and special device. Wherein, the preparation comprises: inserting the sharp hollow punch head with inner sheath into the blank of plant fiber plate to be heated; using compress plate to compress it and attain the plates which has vertical through holes. Said plant fiber comprises the fiber or fiber beams made from wood or non-wood plant; the shape of through hole can be round, regular hexagon, and square, etc; the diameter of through hole is 10-200mm, the hole rate is 20-90%; said through holes are distantly or un-distantly arranged. The inventive plate can effectively reduce the wood consumption; reduce the weight; and support the application for vibration adsorption, sound insulation and thermal insulation. And it is not limited by thickness, to apply door and walls of building.

Description

technical field [0001] The invention relates to a perforated plant fiber board, its manufacturing method and special equipment. Background technique [0002] At present, the fiberboard produced by our country using wood processing residues is generally a solid material with a thickness of 3-40 mm. The main disadvantage is that its own weight is significantly higher than that of wood. Its main use is limited to furniture and floor manufacturing, interior decoration, etc. At present, there is a kind of molded honeycomb structure board in foreign countries. After applying organic adhesive, the wood fiber is paved into a slab of equal thickness, and it is formed by hot pressing through a mold. Modified white latex) Glue two semi-finished products together to make a hollow wood fiber honeycomb panel. The honeycomb hole of this honeycomb panel is a structure with a large inside and a small outside; [0003] CN0020579.2 discloses a molded hollow plant fibe...
