Wood imitation forming products constructed in accordance contains by resin waste and obtains, and contains waste material hybrid resin that thermoplastic resin, thermosetting resin and impurity mix and by pulverizing the wooden waste powder that wooden waste obtains.The the 1st～the 5th embodiment to the manufacture method of Wood imitation forming products describes below.
As shown in Figure 1, in the 1st embodiment, at first, in pulverizing process, pulverize wooden waste and form the wooden waste powder.In addition, this pulverizing process is pulverized and is pulverized this three phases for three times and formed by once pulverizing, secondary.Much less, this pulverizing form is in order to form effectively each stage, but to this not special qualification, also can be undertaken by a kind of pulverizing process.
The shredding unit that uses in a pulverizing process is, has the device that every crushed material is ground into big blocky pulverizing function about several centimetres, specifically, be to form a plurality of projections on the surface of two opposed rollers, make the roller revolution when pressurizeing between this roller, make shredding unit by the material fragmentation between this roller.Much less, shredding unit is not limited to this, can use other coarse reduction shredding units with said function.For example, can use raw material is joined between the V-type jaw upwards opened and the vibration jaw, pulverizes the jaw crusher of raw material by pressurization, perhaps use and the movable plane of disruption rotated in the fixing plane of disruption and other coarse reduction device such as the gyratory crusher of continuous crushing.
Then, in the secondary pulverizing process, the pulverizing of once pulverizing material enforcement finely powdered behind the relative pulverizing process.The shredding unit that uses in this secondary pulverizing process is for being crushed to large-block material below several millimeters, be ground into the device of finely powdered, specifically, use the knocking formula pulverizer of the effect of smashing repeatedly to smash material, up to by being in the circular hole of the sifting machine on the hammer leaf periphery by the hammer leaf of high speed rotary.Much less, employed shredding unit is not limited to described knocking formula pulverizer, can be other shredding units with said function.For example, the knife mill that cuts off by cutting machine or by the broken roll pulverizer of roll-in etc.
Afterwards, in three pulverizing process, the secondary pulverised material behind the secondary pulverizing process is implemented little powdered pulverize.The shredding unit that these three pulverizing process use is for being ground into thinner micro mist shape with the material that the secondary pulverizing process obtains, specifically, by being installed to the pin on the disk in the so-called pin formula pulverizer, accept the interaction of impact, repulsion, it is broken to implement micro mist.More particularly, this pin formula pulverizer has the discoid rotating disk that has a plurality of pins in vertical direction, with in the face of having the shaft collar of a plurality of pins on the face of this rotating disk, when the material that obtains in the secondary pulverizing process drops into to center of turntable portion, under centrifugal action, enter rotating disk and be installed in the gap of the pin on the shaft collar, accept the interaction of impact that pin produces or repulsion and be ground into the micro mist shape.In these three pulverizing process,, can pulverize powder into about 60 microns sizes by described pin formula pulverizer.Much less, shredding unit is not limited to described pin formula pulverizer, can be other fine powder crushing device, for example ball mill or the stone mills etc. with said function.
In described pulverizing process, the wooden waste that reclaims is divided into three phases, pulverizing can effectively be carried out by stages.
