Embodiment Construction

[0016] Such as figure 1 As shown, the longitudinal structure non-layered plant fiber extruder of the present invention includes a mold cavity 2 surrounded by a mold plate 1, and the inner wall of the mold plate 1 of the extrusion cavity section 3 of the mold cavity 2 is gradually inclined to the center, Form the inclined wall 4. The included angle of the slope a of the inclined wall 4 is 30 degrees. At least one boss 8 is provided on the end surface of the extrusion head 7 of the extruder.

[0017] When producing hollow-core extruded products, the cavity 2 is provided with an extruding core 5, and the extruding core 5 can be a currently used cylinder (such as figure 2 As shown), the extrusion core 5 of the present invention can also be used (such as image 3 (Shown), the extrusion die core 5 located in the extrusion cavity section 4 of the die cavity is a frustum 6 whose cross section gradually increases. The included angle of the slope b of the frustum 6 is 30 degrees.

Abstract

The invention discloses a no-delamination vertical structure plant fiber extruder which comprises a die cavity formed by templates; the inner walls of the templates in the extruding cavity section of the die cavity gradually incline towards the center to form inclined walls. When a hollow core extruded product is produced, hole-extruding die cores are arranged in the die cavity, and the hole-extruding die cores in the extruding cavity section of the die cavity are frustum bodies with increasingly large sections. During the extruding and forming process of mixture of plan fibers and glue in the die cavity of the plant fiber extruder, the mixture of plant fibers and glue is subjected to longitudinal pressure, radial pressure from the center to the surrounding, and radial pressure from the surrounding to the center, so the produced plant fiber extruded product has no delamination in the vertical structure and even density, and the strength of the product is improved.

Description

Technical field [0001] The invention relates to the field of plant fiber extruders, in particular to a longitudinal structure non-layered plant fiber extruder. Background technique [0002] Plant fiber extruded products such as plates, wood squares, cylinders, and pipes produced by the extrusion method have excellent characteristics such as heat preservation and heat insulation, light weight and sound absorption, high flatness, and good compression resistance, and can not only use wood as raw materials For production, crop straw can also be used as raw material for production, so the cost is low, and the demand is increasing in recent years. However, the current extruder has no radial pressure when producing plant fiber extruded products. The longitudinal structure generally has a certain degree of layering and uneven density. The product strength is very low and cannot be compared with wood and concrete products. The field is greatly restricted. Summary of the invention [0003...
