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
The present invention relates to string extruder field, be specifically related to the not stratified string extruder of vertical structure.
Background technology
The string extruded product of the sheet material of extrusion molding production, flitch, cylinder, tubing and so on has good characteristics such as insulation, light weight sound-absorbing, flatness height, compressive property be good, and not only can utilize timber to produce for raw material, can also utilize crop stalk to produce for raw material, therefore with low cost, demand was increasing in the last few years.But extruder does not have radial pressure when producing the string extruded product at present, vertical structure generally have certain layering and and the density unevenness phenomenon, product strength is very low, can't compare with timber, concrete material goods, and product applications is subjected to great restriction.
Summary of the invention
The technical problem to be solved in the present invention provides the not stratified string extruder of a kind of vertical structure, and the string extruded product vertical structure of producing is not stratified, and density is even, improves the intensity of goods.
The present invention is achieved through the following technical solutions:
The not stratified string extruder of vertical structure comprises the die cavity that is surrounded by template, and the template inwall of the extrusion chamber section of die cavity forms skew wall gradually to centroclinal.
The further improvement project of the present invention is that the gradient a angle of described skew wall is 20～60 degree.
The present invention further improvement project is, is provided with in the described die cavity to squeeze the casement core, and the crowded casement core that is positioned at the extrusion chamber section of die cavity is that cross section becomes big cone table gradually.
The present invention further improvement project is that described cone table gradient b angle is 20～60 degree.
The present invention further improvement project is that 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, the template inwall of the extrusion chamber section of die cavity forms skew wall gradually to centroclinal among the present invention.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 applies pressure to the center to material, and material is in the extrusion molding process, be subjected to forward longitudinal pressure and peripheral radial pressure to the center simultaneously, the material extruding is more closely knit.
Two, when processing is provided with the string extruded product of hollow, it is that cross section becomes big cone table gradually that the present invention adopts the crowded casement core of the extrusion chamber section of die cavity, the mixed material of string and glue is promoted to extrude forward by extruder head in die cavity, when walking to the extrusion chamber section, material is extruded forward along the cone table gradient of squeezing the casement core, material not only has extruder head to its longitudinal pressure forward, squeeze the casement core material is also had middle mind-set radially pressure all around, in conjunction with the template skew wall material is applied radial pressure to the center, the three parts exerts pressure simultaneously, material is extruded more closely knit, effectively solves 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, the extrusion head end face contacts the degree of depth with the material that is extruded and differs, and better realizes the not stratified effect of material extruding.
Description of drawings
Fig. 1 is the local longitudinal sectional view of the extruder of producing solid extruded product.
Fig. 2, Fig. 3 are the local longitudinal sectional view of the extruder of producing the hollow extruded product.
The specific embodiment
As shown in Figure 1, the not stratified string extruder of vertical structure of the present invention comprises the die cavity 2 that is surrounded by template 1, and template 1 inwall of the extrusion chamber section 3 of described die cavity 2 forms skew wall 4 gradually to centroclinal.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 the hollow extruded product, be provided with in the described die cavity 2 and squeeze casement core 5, described crowded casement core 5 can be present used cylinder (as shown in Figure 2), also can use crowded casement core 5(of the present invention as shown in Figure 3), the crowded casement core 5 that is positioned at the extrusion chamber section 4 of die cavity becomes big cone table 6 gradually for cross section.Described cone table 6 gradient b angles are 30 degree.
The mixed material of string and glue is promoted to extrude forward by extruder head in die cavity, and when walking to the extrusion chamber section, material is extruded forward along the cone table gradient of squeezing the casement core, squeezes the casement core material is had middle mind-set radial pressure all around.Simultaneously the skew wall position of template inwall has radial pressure to the center to material, exert pressure simultaneously to the radial pressure at center in radial pressure around longitudinal pressure, the middle mind-set, periphery, the material extruding is more closely knit, effectively solves the problem of the layering of extruded product vertical structure and density unevenness.
