Abstract
The utility model discloses a plant fiber extruder producing plant fiber extrusion products with hardly layered vertical structures, which comprises a molding chamber formed by the enclosing of templates. The inner walls of templates in the extrusion chamber segment of the molding chamber are gradually inclined towards the center to form oblique walls. When hollow-core extrusion products are produced, a hole-extrusion mold core is arranged inside the molding chamber. The hole-extrusion mold core in the extrusion chamber segment of the molding chamber is a frustum body with a gradually increasing cross section. When mixed materials composed of plant fiber and rubber are molded in an extrusion way in the molding chamber, the materials simultaneously receive longitudinal pressure, radial pressure from the center to the periphery and radial pressure from the periphery to the center. Produced plant fiber extrusion products have vertical structures which are not layered and further achieve uniform density. The strength of products is thus enhanced.
Description
Technical field
The utility model relates to string extruder field, is specifically related to the not stratified string extruder of vertical structure.
Background technology
The good characteristics such as the string extruded product of the sheet material that extrusion molding is produced, flitch, cylinder, tubing and so on has insulation, light weight sound-absorbing, flatness is high, compressive property is 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 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 compare with timber, concrete material goods, and product applications is subject to great restriction.
summary of the invention
The technical problems to be solved in the utility model is to provide the not stratified string extruder of a kind of vertical structure, and the string extruded product vertical structure of producing is not stratified, even density, the intensity of raising goods.
The utility model is achieved through the following technical solutions:
The not stratified string extruder of vertical structure, comprises the die cavity being 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 utility model is that the gradient a angle of described skew wall is 20～60 degree.
The utility model further improvement project is, is provided with and squeezes casement core in described die cavity, and the crowded casement core that is positioned at the extrusion chamber section of die cavity is that cross section becomes large cone table gradually.
The utility model further improvement project is that described cone table gradient b angle is 20～60 degree.
The utility model further improvement project is that the end face of the extrusion head of described extruder is provided with at least one boss.
The utility model compared with prior art, has following obvious advantage:
One, in the utility model, 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, while walking to the extrusion chamber section of die cavity, the skew wall of template applies the pressure to center to material, and material is in extrusion molding process, be subject to longitudinal pressure and the peripheral radial pressure to center forward, material extruding is more closely knit simultaneously.
Two, when processing is provided with the string extruded product of hollow, it is that cross section becomes large cone table gradually that the utility model 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, while walking to extrusion chamber section, material is extruded forward along the cone table gradient of squeezing casement core, material not only has extruder head to its longitudinal pressure forward, squeeze casement core material is also had to middle mind-set surrounding pressure radially, in conjunction with template skew wall, material is applied to the radial pressure to center, tripartite exerts pressure simultaneously, material is extruded more closely knit, effectively solve extruded product vertical structure lamination problem.
Three, the end face of the extrusion head of extruder described in the utility model is provided with at least one boss, and during extruding, extrusion head end face contacts the degree of depth with the material being extruded and differs, and better realizes material and pushes not stratified effect.
Accompanying drawing explanation
Fig. 1 is for producing the local longitudinal sectional view of extruder of solid extruded product.
Fig. 2, Fig. 3 are for producing the local longitudinal sectional view of extruder of hollow extruded product.
The specific embodiment
As shown in Figure 1, the not stratified string extruder of vertical structure described in the utility model, comprises the die cavity 2 being 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, in described die cavity 2, be provided with and squeeze casement core 5, described crowded casement core 5 can be current cylinder (as shown in Figure 2) used, also can use crowded casement core 5(of the present utility model as shown in Figure 3), the crowded casement core 5 that is positioned at the extrusion chamber section 4 of die cavity becomes large 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 while walking to extrusion chamber section, material is extruded forward along the cone table gradient of squeezing casement core, squeezes casement core and material is had to the radial pressure of middle mind-set surrounding.The skew wall position of template inwall has the radial pressure to center to material simultaneously, exert pressure to the radial pressure at center in the radial pressure of longitudinal pressure, middle mind-set surrounding, periphery simultaneously, material extruding is more closely knit, effectively solves the problem of the layering of extruded product vertical structure and density unevenness.
