Plant fiber extruded product with internal weft ribs, extruder and production method

Abstract

The invention discloses a plant fiber extruded product containing horizontal bars, as well as an extruding machine and a production method. The plant fiber extruded product comprises a product body, wherein a longitudinal through hole is formed in the product body, and horizontal bars are arranged at the periphery of the longitudinal through hole in the product body; or longitudinal bars are arranged in the product body, and the horizontal bars are arranged at the peripheries of the longitudinal bars in the product body; or the longitudinal through hole is arranged in the product body, the longitudinal bars are arranged at the periphery of the longitudinal through hole, and the horizontal bars are arranged at the peripheries of the longitudinal bars in the product body. According to the invention, horizontal bars and / or longitudinal bars are arranged in the product body, so that the key technological problem that the structural strength of a plant fiber extruded product is poor is solved; strengthening bars can be automatically and continuously distributed in the plant fiber extruded product so as to realize automatic and continuous production; the plant fiber extruded product, which has the superior properties of large structural strength, high flatness and the like, can be broadly promoted and applied, so as to ease the situation of critical shortage of timber resources; furthermore, the cost of plant fibers, such as straw, is low; meanwhile, a new approach for efficiently utilizing straw is developed to increase the income of peasants.

Description

technical field [0001] The invention relates to the field of plant fiber extruded products and production equipment and production technology thereof, in particular to plant fiber extruded products with internal weft ribs, an extruder and production method for producing plant fiber extruded products with internal weft ribs. Background technique [0002] my country is a large agricultural country, and there are as many as 700 million tons of crop straws every year. Because there is no suitable way to convert them into economic benefits, most of them are incinerated, which has brought extremely serious environmental pollution problems. At the same time, there is a serious shortage of timber resources in our country. In recent years, through continuous exploration, researchers have developed plant fiber extrusion products such as boards, wood cubes, columns, and pipes by extrusion to replace the consumption of timber resources. However, the strength of plant fiber extruded prod...

Problems solved by technology

The grid-shaped reinforcing ribs are set in the middle of the upper and lower surfaces of the tray plate. The tray can more than double the load capacity of the plate without increasing the thickness of the plant fiber tray plate. However, this method can only use the plant fiber made by the flat pressing method. Pressed products and reinforcements can only use hard reinforcements such as bamboo, wood chips or metal sheets or rods, which are not easy to achieve continuous production, such as plates, wood squares, columns, pipes, etc. Plant fiber extruded products with reinforced ribs can not be realized

Therefore this kind of product also restricts its popularization and application because of its strength problem can not be solved
