Description
The present invention relates to a kind of method and a kind of production line of realizing this method of making vegetable material building board or other goods.
The present invention will be widely used in the furniture manufacturing of wood-processing industry.
447～449 pages of process technologies that disclose a kind of plank that the N.G. Luo Mengnuofu that Moscow Lesnaya Promyshlennost publishing house publishes nineteen sixty-five shows " wood plastic and manufacturing method of plate thereof " book.This technology comprises the preparation of drying, the bonding agent of hogging, crushing material, with this adhesive applicating to the surface of wood substance grain and operation such as compression molding.
A kind of timber is by equipment fragmentations such as weight grinder, cam bruishers, and material that then should fragmentation is dry in pneumatic, rotary drum, continuous conveyor or other drying machine.Bonding agent can be by urea aldehyde, phenolic aldehyde and the preparation of other resin.Use the mixer of running continuously or intermittent running, for example rotary drum and blade mixer mix raw material fragment and adhering resin.Utilize the multiple exit hydraulic press compression molding of continuous track forcing press or intermittent running to sneak into the wood chip of bonding agent.
The method of above-mentioned manufacturing wood chip sheet material has following shortcoming, applied adhering resin in mold process and goods distribute toxic gas between the operating period and contaminated environment.
The Russian Patent application has disclosed a kind of pressing method of well-known manufacturing wood chip sheet material for No. 10216310.This method comprises the feed hopper that the wood chip of application of resin is fed to a forcing press.Wood chip enters in the embossed channel and space former of heating plate formation then.The wood chip sheet material of mold pressing shifts out the press passage with continuous band-shaped form under the acting in conjunction of the heat of head pressure, heating plate and space former outer surface.
Yet, resin be applied in the mold process and end product causes the pollution of environment because of poisonous formaldehyde between the operating period.What BSSR state, Minsk publishing house nineteen sixty published shows in " utilizing mold pressing production to grind wood chip products and material " book the 123rd page to 127 pages and has disclosed a kind of manufacturing vegetable material building board of bonding agent or method of goods of need not adding by A.N. rice is peaceful.This method comprises delivers to crusher in crushing with the raw material of raw material humidification, humidification, broken material screening, and it is broken once more and remaining wood pulp is delivered to a hopper that thicker particle enters disintegrating machine.This material use metering feeder is fed to drier (pneumatic, as to agitate and other drier) from hopper automatically.Dry material enters another hopper, and the material unification is proceeded in the chain type pulsation conveyer that is provided with pressing mold by a metering feeder from this hopper, and after this material is delivered in the hydraulic press that works by day and is preheated to the thermoplastic state.The pressing mold that has compression material in a radio-frequency field after the material mold pressing of preheating is delivered to the feed arrangement of many cracking pressures of hydraulic pressure machine by same conveyer.Pressure plare is opened in cooling, unloads the mold pressing pressing mold that has end product afterwards.Yet this method is loaded down with trivial details and because huge energy consumption causes the cost costliness.Operate length by length and utilize the production efficiency of many cracking pressures machine mold pressing very low.
An object of the present invention is to provide a kind of production line of making the method for vegetable material building board or other goods and using this method; owing to all do not use adhering resin in operation and the extrusion modling and to the appropriate design of this operation; make this method and production line guarantee that building board or other goods produced have good ecological protection effect, and improved physical mechanical characteristic and high production efficiency.
An object of the present invention is to provide the method for described processing vegetable material building board and other goods, this method comprise fragmentation, drying, particle transportation, at an enclosure space particle is preheated to thermoplastic state, mold pressing, and the steps such as cooling of goods subsequently, according to the present invention, the drying of crushing material is finished during this particle is preheated to the thermoplastic state, preheating is carried out in course of conveying, and compression molding is finished by an extruder.
Particle is simultaneously dry and be preheated to the thermoplastic state and make the prefabricated time of moulding material shorten during the conveying, i.e. formation along with resin makes material reach maximum fluidity.
This method has been improved physical and mechanical properties owing to improved the productivity ratio of uncontamination building board or other goods, thus under the situation of not using urea aldehyde or other resin, further shortened the compression molding time, and guaranteed continuously extruded formula compression molding.
Preferably the humidification of vegetable material is undertaken by saturated vapor.This is convenient to material ground and reduced energy in disintegrating machine consumption.
