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

Abstract

The invention discloses a plant fiber extruded product containing vertical bars, as well as an extruding machine and a production method. The plant fiber extruded product comprises a product body, wherein the vertical bars, longitudinal bars and horizontal bars are arranged in the product body, and the product body is manufactured through extruding and bonding crop straw fibers and glue. According to the invention, three-dimensional strengthening bars, namely the X-axis horizontal bars, the Y-axis longitudinal bars and the Z-axis vertical bars, are arranged in the plant fiber extruded product, and the overall structure of the plant fiber extruded product is molded by extruding, so that the structural strength is extremely high, and the flatness is excellent; the 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 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 present invention relates to the field of plant fiber extruded products, production equipment and production methods thereof, in particular to plant fiber extruded products with internal vertical ribs, an extruder and production method for producing plant fiber extruded products with internal vertical 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 by farmers, 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. This type of product has ex...

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 pressure of the plate without increasing the thickness of the plant fiber tray plate. However, this method can only be used for plants made by the flat pressing method. For fiber pressed products, the flat pressing method can only set the X-axis weft ribs and Y-axis longitudinal ribs, but cannot set the Z-axis vertical ribs, and the reinforcing ribs can only be made of bamboo, wood chips or metal sheets or rods. It is not easy to achieve continuous production, such as planks, wood squares, columns, pipes, etc., which are long in length and continuously produced with plant fiber extrusion products with reinforcement ribs.

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