Molding method and molding mechanism for a biologic material of fabricable material

Abstract

A molding method for biomass moldable materials, which comprises crushing the biomass materials into loose granules, and then extruding them; wherein, at least one wedge-shaped extrusion is formed between the extrusion head and the extrusion surface of the molding die. Cavity, the relative movement of the extrusion head and the extrusion surface of the forming die at a differential speed, the granular materials squeezed between them are rolled and stretched into sheets during the relative movement, and the extrusion head and the forming The effect of the relative movement of the extrusion surface of the mold extrudes to the small end of the wedge-shaped extrusion cavity, and then extrudes into the forming cavity of the molding die for forming. The molding method and its device of the present invention can provide the molded product with certain connection strength and moisture resistance without using any chemical adhesive, so as to maintain its normal use state and facilitate storage, and can Minimize its manufacturing, transportation and storage costs.

Description

technical field [0001] The invention relates to a molding method of a loose biomass material, which can form the loose biomass material into various required shapes without relying on any chemical adhesive, and has sufficient connection strength. Background of the invention [0002] The biomass formable material referred to in the present invention uses solid waste produced in wood processing, straw of agricultural crops, or herbaceous plants, shrubs, etc. Materials that can become available profiles. The raw material of this biomass material is composed of the waste produced by natural plants, which has the characteristics of low cost, renewable and abundant resources. [0003] At present, the utilization of this biomass material mainly includes the following aspects: [0004] 1. Press loose materials into wood-based panels or other profiles, such as fiberboard, particle board, etc., for furniture manufacturing, decoration engineering and other fields. The traditional ma...

AI Technical Summary

Problems solved by technology

[0012] One, due to the adoption of this method, the material must be dried in advance so that its moisture content is less than 10%, which requires a large amount of energy consumption under the conditions of large-scale factory production;

[0013] Second, when the material is dried to a moisture content of less than 10% and then extruded, its friction force is greatly increased, thereby increasing the resistance during extrusion and making the unit energy consumption of the product too high;

[0014] Third, during the curing and molding process, a large amount of energy is consumed due to the need for heat treatment

A large number of practices have proved that it is precisely because of the excessive energy consumption and high processing cost of the molding and processing of biomass materials that the molding and processing of biomass materials cannot be widely promoted so far.

[0015] Second, due to the existing method of biomass molding, which requires a large power support, it must be in a site with high-pressure power conditions and adopt a centralized production method

As we all know, the collection and transportation radius of biomass materials in a loose state is extremely large, so the transportation and storage costs of materials are also extremely high, which is also an important factor for the high cost of biomass material molding and processing

[0016] Third, practice has proved that the products formed according to the above method have the defects of high brittleness and poor water resistance. When the formed product is damp, its connection strength is greatly reduced and it is very easy to be crushed. For example, biomass burning materials processed by the above method , it becomes powder after a few minutes in water

The inventors have conducted a lot of research on the force conduction properties of this material and found that the force conduction of this loose biomass material is poor

Therefore, when all the large gaps between the particles are occupied by the particles that can enter, even if the pressure is increased, the deformation of the particles themselves is small, and it is difficult to achieve the purpose of making them fully extendable, so that the formed product is in the distance between the particles. Difficult to achieve ideal chimerism

And this problem is an important core technical problem that the existing molding method is neglected

[0019] Fifth, the above-mentioned biomass material molding equipment usually adopts a screw extrusion biomass molding machine, which has a complex structure and low production efficiency
