Abstract
The invention discloses the not stratified plant fiber extruder of vertical structure, comprise the die cavity surrounded by template, the template inwall of the extrusion chamber section of described die cavity, gradually to centroclinal, forms skew wall.When producing hollow extruded product, be provided with crowded casement core in described die cavity, the crowded casement core of the extrusion chamber section of die cavity is the cone table that cross section becomes large gradually.The mixed material of string and glue is in die cavity of the present invention in extrusion molding process, be subject to longitudinal pressure and center to the radial pressure of surrounding, the peripheral radial pressure to center simultaneously, the string extruded product vertical structure produced is not stratified, even density, improves the intensity of goods.
Description
Technical field
The present invention relates to plant fiber extruder field, be specifically related to the not stratified plant fiber extruder of vertical structure.
Background technology
The good characteristics such as string extruded product has insulation, light weight sound-absorbing, flatness is high, compressive property is good of sheet material, flitch, cylinder, tubing and so on that extrusion molding is produced, and timber not only can be utilized to produce for raw material, crop stalk can also be utilized to produce for raw material, therefore with low cost, demand was increasing in the last few years.But at present extruder when producing string extruded product without radial pressure, vertical structure generally have certain layering and and density unevenness phenomenon, product strength is very low, cannot compared with timber, concrete material goods, and product applications is subject to great restriction.
Summary of the invention
The technical problem to be solved in the present invention is to provide the not stratified plant fiber extruder of a kind of vertical structure, and the string extruded product vertical structure produced is not stratified, even density, improves the intensity of goods.
The present invention is achieved through the following technical solutions:
The not stratified plant fiber extruder of vertical structure, comprises the die cavity surrounded by template, and the template inwall of the extrusion chamber section of die cavity, gradually to centroclinal, forms skew wall.
The further improvement project of the present invention is, the gradient a angle of described skew wall is 20 ~ 60 degree.
The present invention further improvement project is, is provided with crowded casement core in described die cavity, and the crowded casement core being positioned at the extrusion chamber section of die cavity is the cone table that cross section becomes large gradually.
The present invention further improvement project is, described cone table gradient b angle is 20 ~ 60 degree.
The present invention further improvement project is, the end face of the extrusion head of described extruder is provided with at least one boss.
The present invention compared with prior art, has following obvious advantage:
One, in the present invention, the template inwall of the extrusion chamber section of die cavity, gradually to centroclinal, forms skew wall.The extruder head of extruder promotes material and moves ahead in die cavity, when walking to the extrusion chamber section of die cavity, the skew wall of template is to the pressure of material applying to center, and material is in extrusion molding process, be subject to longitudinal pressure forward and the peripheral radial pressure to center, express material is more closely knit simultaneously.
Two, when processing is provided with the string extruded product of hollow, the present invention adopts the crowded casement core of the extrusion chamber section of die cavity to be the cone table that cross section becomes large gradually, the mixed material of string and glue is promoted to extrude forward by extruder head in die cavity, when walking to extrusion chamber section, material is extruded forward along the cone table gradient of crowded casement core, material not only has extruder head to its longitudinal pressure forward, squeeze casement core, to material, also there is the pressure of center to surrounding radial direction, in conjunction with template skew wall to the radial pressure of material applying to center, tripartite exerts pressure simultaneously, material is extruded more closely knit, effective solution extruded product vertical structure lamination problem.
Three, the end face of the extrusion head of extruder of the present invention is provided with at least one boss, and during extruding, extrusion head end face contacts the degree of depth with the material be extruded and differs, and better realizes the effect that express material is not stratified.
Accompanying drawing explanation
Fig. 1 is the extruder partial lengthwise sectional view producing solid extruded product.
Fig. 2, Fig. 3 are the extruder partial lengthwise sectional view producing hollow extruded product.
Detailed description of the invention
As shown in Figure 1, the not stratified plant fiber extruder of vertical structure of the present invention, comprises the die cavity 2 surrounded by template 1, and template 1 inwall of the extrusion chamber section 3 of described die cavity 2, gradually to centroclinal, forms skew wall 4.The gradient a angle of described skew wall 4 is 30 degree.The end face of the extrusion head 7 of described extruder is provided with at least one boss 8.
When producing hollow extruded product, crowded casement core 5 is provided with in described die cavity 2, described crowded casement core 5 can be cylinder (as shown in Figure 2) used at present, also crowded casement core 5(of the present invention can be used as shown in Figure 3), the crowded casement core 5 being positioned at the extrusion chamber section 4 of die cavity is the cone table 6 that cross section becomes large gradually.Described cone table 6 gradient b angle is 30 degree.
The mixed material of string and glue is promoted to extrude forward by extruder head in die cavity, and when walking to extrusion chamber section, material is extruded forward along the cone table gradient of crowded casement core, squeezes casement core and has the radial pressure of center to surrounding to material.Simultaneously the skew wall position of template inwall has radial pressure to center to material, longitudinal pressure, radial pressure from center to surrounding, peripheral to exert pressure to the radial pressure at center simultaneously, express material is more closely knit, effectively solves the problem of extruded product vertical structure layering and density unevenness.
