Background technology
China Shi Yige large agricultural country, annual crop stalk has 700,000,000 tons more than, and because not finding the suitable path that is converted into economic benefit at present, majority is incinerated, and has brought extremely serious problem of environmental pollution.The timber resources of China critical shortage again simultaneously, scientific research personnel, by constantly exploring, develops with extrusion molding and produces as the string extruded product of sheet material, flitch, cylinder, tubing and so in recent years, to the consumption of alternative timber resources.
This based article has the good characteristics such as density is little, impact resistance is strong, insulation, light weight sound-absorbing, flatness height, but the goods that the conventional extruder using is produced at present also exist numerous defects.One, string extruded product intensity is low, and special longitudinal strength is poorer, cannot compare with timber, concrete material goods, cannot widely popularize; Two, because the die cavity end section at the whole story that extruder template surrounds is at present consistent, the longitudinal pressure that only has extrusion head to apply in extrusion, the goods vertical structure layering of extruding out, Density inhomogeneity; Three, the outer surface of goods body is coarse, does not have water resistance, as wet wet environment, is easy to modification, service life large heavy discount; Four, goods are at die cavity inner heating drying, generally by heating platen, provide heating function, but the heat that heating platen transmits is circumferentially center exhaustion gradually from die cavity, heat is inhomogeneous, causes extruded product to be heated in forming process inhomogeneous, and the temperature of heating platen can not be too high, otherwise glue can precuring before extrusion molding, affect product strength, therefore only depend on heating platen heating slowly, production efficiency can not get improving.The quality problems that more than exist have a strong impact on and have restricted promoting the use of extruded product.
Summary of the invention
The present invention is directed to the problem of above existence, a kind of novel plant fiber extruder be provided, the goods of extruding can in establish reinforcement, vertical structure is not stratified, greatly improves intensity; Surface has watertight composition, adapts to wet environment and uses, long service life; Heating using microwave is solidified, and production efficiency is high.
The present invention is achieved through the following technical solutions:
Novel plant fiber extruder, comprises extrusion head and the die cavity being surrounded by template, and extrusion head is reciprocating in die cavity stroke chamber, and described die cavity is comprised of stroke chamber, extrusion chamber, moulding coating chamber, the chamber that is heating and curing successively.
The further improvement project of the present invention is, described extrusion head rear side is provided with friction holder, offers reinforcement through hole on extrusion head, and the die cavity port of export is provided with fixture, reinforcement successively through friction holder, reinforcement through hole, die cavity, be fixed on fixture.
The present invention further improvement project is, the template in described stroke chamber is divided and cut in two, and by middle rotation template, is flexibly connected, and offers through hole on rotation template, and the expansion link of retractor device is located in through hole, and rotation template and drive unit are in transmission connection.
The present invention further improvement project is, the template inwall of described extrusion chamber, gradually to centroclinal, forms skew wall, and the gradient a angle of skew wall is 20～60 degree.
The present invention further improvement project is, is provided with and squeezes casement core in described die cavity, and being positioned at extrusion chamber, to squeeze casement core be that cross section becomes large cone table gradually, and cone table gradient b angle is 20～60 to spend.
The present invention further improvement project is, top, described moulding coating chamber template offers waterproof top layer solution feed mouth, the template internal perisporium of solution feed mouth position, waterproof top layer offers a groove and spacing shaft to the b groove of offering, b groove is communicated with a groove, b groove extends to die cavity discharging opening direction, on a groove and b groove, be coated with interior lining panel, offer axial slits on interior lining panel, gap and b groove shift to install.
The present invention further improvement project is, described in be heating and curing in the template in chamber and offer breach, in breach, fill microwave penetration plate, microwave penetration plate is provided with microwave heating equipment outward, described microwave heating equipment is comprised of the microwave tube in chamber and anti-leak baffle plate.
The present invention further improvement project is, described breach is offered in template around die cavity one week, described microwave penetration plate inwall flushes with template inwall, and outer wall periphery fixes on template outer wall, in anti-leak baffle plate, and described anti-leak baffle plate and template are by welding or bolt is fixedly connected with.
The present invention further improvement project is, before and after described microwave penetration plate, on the cavity wall that is heating and curing of section, offers anti-microwave leakage groove, in anti-microwave leakage groove, is filled with resin.
The present invention compared with prior art, has following obvious advantage:
One, in the present invention, be provided with latitude muscle and/or vertical muscle, solved the poor key technical problem of string extruded product structural strength.Reinforcement can automation, serialization is distributed into, make to have the string extruded product that is provided with reinforcement of the advantageous characteristic such as structural strength is large, flatness is high, realize automated production, obtain extensive propagation and employment, alleviated the present situation of China's timber resources critical shortage, and straw plant fiber cost is cheap, for stalks utilization, open up new approach simultaneously, increase farmers' income.
Two, in the present invention, the template inwall of the extrusion chamber of die cavity, gradually to centroclinal, forms skew wall.The extrusion 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 is extruded more closely knit simultaneously.When processing is provided with the string extruded product of hollow, the crowded casement core that the present invention is positioned at extrusion chamber position is that cross section becomes large cone table gradually, the mixed material of string and glue is promoted to extrude forward by extrusion 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 extrusion 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 present invention in process of production, waterproof top layer flow of solution enters goods body surface in die cavity, can reduce the frictional resistance of die cavity and goods, squeeze and make the string extruded product extruding there is smooth surface and good water resistance, durable, waterproof surface solution has also had lubricious effect to extruded product simultaneously, enhances productivity.
