8, pellet is pulverized: with the above-mentioned cooling block material that obtains; the blade type pelleter hopper of packing into; pulverizer rolls by the blade type cutting piece material is pulverized automatically; the screen cloth that meets aperture that size particles is provided with through the pulverizer bottom and be 5mm flows out to Material collecting box for harvesting, obtains the graininess composite wooden material of the irregular bodily form of required 0.5～5mm particle diameter.
Four, the moulding of reconstituted wood composite Wood-plastic profiles
As raw material, the hot blast temperature of putting into the setting of heat preservation and dryness machine inner drying machine is 80～85 ℃ with the above-mentioned graininess composite wooden material that obtains; Double screw extruder is warmed up to 160～185 ℃ simultaneously, the mould temperature heats up more than 160 ℃; Then raw material is taken out in the heat preservation and dryness machine and drop into the double screw extruder hopper, the rotating speed and the pressure that start extruder and adjust extruder enter forming process, and the maximum temperature of extruder is controlled at below 195 ℃; Material in the extruder hopper is extruded the machine screw motion and sends into the screw tube chamber, through the heater of extruder and the effect of screw slot variation, finish compression exhaust, thermoplastic, the closely knit process of thermoplastic with the material that screw axial moves in screw extruder, the material that the thrust that is produced by the extruder screw motion is closely knit with thermoplastic is clamp-oned mould by connecting the cavity flange again; The closely knit material of thermoplastic is still finished filling, thermoplastic shaping, crystallisation by cooling process and is obtained the Wood-plastic profiles blank with move mode in mould, continuation is squeezed depanning in the course of work that pushes away continuously at extruder, obtains the Wood-plastic profiles shaping blank of same cross sectional shape and random length; , obtain the Wood-plastic profiles consistent with the natural timber grain of wood after the scale saw is cut out, husky light.
Above-mentioned forming process is a continuous plant equipment course of work, and manually-operated is only carried out touch parameter adjustment for the supporting display screen of surveillance equipment, the adding gentle cooling and will adjust to the control requirement automatically of extruder.
Above-mentioned mould is formed the channel-type mould by filling cavity, inner tube of a tyre core, shell, according to the boundary of action function and temperature, is divided into filling area, thermoplastic shaping district, crystallisation by cooling district in theory; Filling area and thermoplastic shaping zone temperatures are controlled at 185～175 ℃, and the temperature in crystallisation by cooling district is controlled at 175 ℃ and falls progressively to 65 ℃; Filling area and thermoplastic shaping district are furnished with the electrode pair mould heats, by display screen observe variations in temperature and as required at any time touch display screen adjust temperature; The crystallisation by cooling district is furnished with interior recirculated cooling water duct, the operation of the outer loop of plugging into cooling water system; The adjustment of mold temperature is to observe variations in temperature by display screen, and the open and close cooling water valve that is located at mould chassis side is adjusted temperature at any time as required.
Above-mentioned scale saw is cut out, sand only adopts the wood working machine of existing market maturation to finish.
