Abstract
The invention discloses a plant fiber extruded product internally provided with longitudinal bars, an extruder and a production method. The plant fiber extrude product comprises a product body, and the longitudinal bars are arranged in the product body. The longitudinal bars are cellosilks or ropes or wires or metal bars or bamboo poles or reed poles. The product body is formed by bonding and extruding crop straw fibers and glue. The longitudinal bars are arranged in the plant fiber extruded product so as to solve the key technical problem that the plant fiber extruded product is low in longitudinal strength. The reinforcing bars can be arranged in the product automatically and continuously, and therefore the plant fiber extruded product which has the advantages of being high in structural strength, high in flatness and the like can achieve automatic production, and can be widely popularized and applied so as to become a feasible scheme. The phenomenon of severe shortage of wood resources in China is relieved, straw plant fiber is low in cost, a new approach is provided for efficient utilization of straw, and incomes of peasants are increased.
Description
Technical field
The present invention relates to string extruded product and production equipment thereof, production technology field, establish the string extruded product of vertical muscle in being specifically related to, for the production of interior extruder and production method of establishing the string extruded product of vertical muscle.
Background technology
China is a large agricultural country, and annual crop stalk has 700,000,000 tons more than, and is most by peasant's burning disposal because not finding at present the suitable path that is converted into economic benefit, brought extremely serious environmental pollution problem.The timber resources of China critical shortage again simultaneously, the scientific research personnel is by constantly exploring in recent years, develops the string extruded product with extrusion molding production such as sheet material, flitch, cylinder, tubing and so on, in the hope of substituting the consumption of timber resources.This based article has good characteristics such as density is little, impact resistance is strong, insulation, light weight sound-absorbing, flatness height, but string extruded product endwise tensile strength is very low, can't compare with timber, concrete material goods, can't widely popularize.
The inventor applied for the Patent project of " being provided with plant fiber tray of reinforcement and preparation method thereof " (application number is 200810018462.0), this application is put the sheet of bamboo and wood sheet or metal material or bar and is the plane net trellis, insert in the plate die cavity after fixedly connected then, add string in the plate die cavity again and suppress, be solidified into pallet with the mixture of glue.Latticed reinforcement is arranged in the middle of the pallet plate upper and lower surface, this pallet is under the situation that does not increase plant fiber tray plate thickness, plate is born pressure and is enhanced about more than once, but the string stampings that the method can only use flat-press process to make, reinforcement also can only use as the sheet of bamboo and wood sheet or metal material or the hard reinforcement of bar type, be difficult for realizing serialization production, then can't realize as the length string extruded product that is provided with reinforcement long, that continuity is produced of sheet material, flitch, cylinder, tubing and so on.Therefore this based article also restricts its promotion and application because its strength problem can't solve.
Summary of the invention
The technical problem to be solved in the present invention provides the string extruded product of establishing vertical muscle in a kind of, and its structural strength height, flatness height can be realized serialization production.The present invention simultaneously also provides extruder and the production method of establishing the string extruded product of vertical muscle for the production of interior.
The present invention is achieved through the following technical solutions:
In establish the string extruded product of vertical muscle, comprise the goods body, be provided with vertical muscle in the described body.
The further improvement project of the present invention is to be provided with through hole along vertical muscle direction in the described body.
The present invention's further improvement project again is that described vertical muscle is filament, rope, steel wire, Metallic rod, bamboo bar or reed rod.
The present invention more further more improvement project be that described body is that crop stalk fiber and glue bond extruding forms.
The present invention more further more improvement project be that described glue is living beings glue, comprises lignin-base glue or starch based glue.
For the production of the interior extruder of establishing the string extruded product of vertical muscle, comprise extrusion head and the die cavity that is surrounded by template, extrusion head is reciprocating in die cavity stroke chamber, described extrusion head rear side is provided with the friction holder, offer reinforcement on the extrusion head and pass the hole, the die cavity port of export is provided with fixture, and vertical muscle passes the friction holder successively, reinforcement passes hole, die cavity, is fixed on the fixture.
The further improvement project of the present invention is, is provided with the applying glue box between described friction holder and the extrusion head, and vertical muscle activity penetrates the applying glue box.
The present invention more further more improvement project be that described friction holder is friction pulley.
In establish the string extruded product of vertical muscle production method, may further comprise the steps:
(1) with one or more vertical muscle movable penetrating after the friction holder of extruder, reinforcement on the extrusion head pass hole, die cavity successively respectively, is fixed on the fixture of the die cavity port of export, makes vertical muscle tension be in tight state;
(2) string and glue are mixed by 60～97:3～40 part by weight, be loaded in the feed hopper of extruder, when the each backstroke of extrusion head, the mixture of string and glue relies on gravity to fall into the stroke chamber by setting gauge, and extrusion head is pushed the mixture of string and glue to port of export direction during to front travel in die cavity, effect forms continuous idiosome down repeatedly, curing molding, and release die cavity, be cut into the goods of predetermined length by briar.
The present invention further improvement project is that it is coated with glue to described vertical muscle before running through extrusion head.
The present invention compared with prior art has following obvious advantage:
One, is provided with the vertical muscle of rope, steel wire or Metallic rod, bamboo bar or reed rod and so in the present invention, solved the low key technical problem of string extruded product longitudinal strength.But reinforcement automation, serialization are distributed into, the feasible string extruded product that is provided with reinforcement with advantageous characteristic such as structural strength is big, flatness height, realize automated production, extensively promoted and used, alleviated the present situation of China's timber resources critical shortage, and the straw plant fiber cost is cheap, improves the business economic benefit; Open up new approach for the stalks utilization simultaneously, increase farmers' income.
Two, body of the present invention can be the extruded product of multiple shape of cross sections such as sheet material, flitch, cylinder, is provided with through hole along vertical muscle direction in the body, has alleviated product weight, but because the setting of vertical muscle, longitudinal strength but improves a lot.
Three, the present invention adopts extrusion molding, and living beings glue can satisfy the structural requirement that connects crop stalk fiber extruded product, avoids using common " three-aldehyde glue " with the residual release of formaldehyde, and the residual burst size of formaldehyde of the present invention is similar to zero.
Four, in the production method of the present invention, it is coated with glue to described vertical muscle before running through extrusion head, makes the bonding better of goods body and vertical muscle.
