Particularly, in order to optimal screening screening effect, the hook serrated knife groove 4 on inclined-plane charging tray 3 is set to 3 ~ 6 circles.Preferably, hook serrated knife groove 4 and be set to 4 circles, from center outwards, interior 3 circles often enclose 4 mutually in alternative form, and outermost one circle is 8.
Particularly, in order to optimal screening effect is smooth and easy with bark 8 blanking screened out, rotary scraping 5 is set as 3 ~ 6, and every sheet is provided with 3 ~ 6 hook serrated knives 6.
Particularly, according to the blanking velocity of bark 8 and mixed material, the diameter of setting inclined-plane charging tray 3 is 2 ~ 6 meters.
Disc type bark screens out mechanism control method: the discharge efficiency of comprehensive short wooden stick 9, the efficiency of screen out of bark 8, the rotating speed of setting rotary scraping 5 is 50 ~ 80 r/min, this rotating speed makes bark 8 be screened out well, the bark 8 screened out also can not be wrapped on rotary scraping 5, and short wooden stick 9 also can because the effect of centrifugal force and gravity be well to surrounding discharge on slant face disc 3.
beneficial effect
Disc type bark disclosed by the invention screens out mechanism and control method tool has the following advantages:
One, the utilization rate of the short wooden stick mixed in bark in fibreboard fabrication is improved;
Two, the short-and-medium wooden stick of bark screen out effective, screening effeciency is high.
Accompanying drawing explanation
Fig. 1 is the front view that disc type bark disclosed by the invention screens out mechanism;
Fig. 2 is the top view that disc type bark disclosed by the invention screens out mechanism;
Fig. 3 is the rotary scraping schematic diagram that disc type bark disclosed by the invention screens out mechanism.
Detailed description of the invention
Disc type bark disclosed by the invention screens out mechanism and control method will by preferred embodiment is for illustration and explanation below, and not illustrate to being limited property, embodiment wherein only provides as an example with reference to accompanying drawing, is described.
With reference to Fig. 1 ~ Fig. 3, the structure of mechanism is screened out to disc type bark disclosed by the invention and screening principle is described.
The structure that disc type bark screens out mechanism illustrates:
Disc type bark screens out mechanism and comprises: feed opening 1, material distributing cone cylinder 2, inclined-plane charging tray 3, hooks serrated knife groove 4, rotary scraping 5, hooks serrated knife 6, supports hopper 7.Wherein, inclined-plane charging tray 3 is provided with and hooks serrated knife groove 4, rotary scraping 5 is provided with and hooks serrated knife 6.Screen out in process, bark can disperse by material distributing cone cylinder 2, drops on inclined-plane charging tray 3, and rambling bark catches on and twists down through hooking serrated knife groove 4 by hook serrated knife 6, and falls into support hopper 7 under hooking.
Particularly, it is 5 ~ 30 degree that the inclined-plane charging tray 3 that disc type bark disclosed by the invention screens out mechanism is set to bevel angle, in coniform.
Particularly, the hook serrated knife 6 that disc type bark disclosed by the invention screens out mechanism is tiny hook tooth, in inclined teeth shape.Tiny hook tooth only can catch on bark, and short waddy can skid rotation thereon, can not be caught on and snap into.
Particularly, in order to optimal screening screening effect, the hook serrated knife groove 4 on inclined-plane charging tray 3 is set to 3 ~ 6 circles.Preferably, hook serrated knife groove 4 and be set to 4 circles, from center outwards, interior 3 circles often enclose 4 mutually in alternative form, and outermost one circle is 8.
Particularly, in order to optimal screening effect is smooth and easy with bark 8 blanking screened out, rotary scraping 5 is set as 4, and every sheet is provided with 5 hook serrated knives 6.
Particularly, according to the blanking velocity of bark and mixed material, the diameter of setting slant face disc is 3 meters.
The control method that disc type bark screens out mechanism illustrates:
The discharge efficiency of comprehensive short waddy, the efficiency of screen out of bark, the rotating speed of setting rotary scraping 5 is 67r/min, and this rotating speed bark can be good at screening out, the bark screened out also can not be wrapped on rotary scraping 5, and short waddy also can because centrifugal force be well to surrounding discharge on slant face disc 3.
The mixed material of bark 8 and short wooden stick 9 is discharged from feed opening 1, fall on material distributing cone cylinder 2, the mixed material of bark 8 and short wooden stick 9 is distributed on inclined-plane charging tray 3 by material distributing cone cylinder 2, because the rotary scraping 5 below inclined-plane charging tray 3 is in rotation, rambling bark 8 can catch on and twist down through hooking serrated knife groove 4 by the hook serrated knife 6 on rotary scraping 5, and under hooking, fall into support hopper 7, by the Action of Gravity Field that rotary centrifugal force and inclined-plane charging tray 3 are formed, the mixed material of bark 8 and short wooden stick 9 can spread to surrounding, wherein bark 8 can be screened out gradually, short wooden stick 9 also can roll along with the outer ring scraped to inclined-plane charging tray 3 of rotary scraping 5, last short wooden stick 9 can drop from inclined-plane charging tray 3 surrounding, thus complete the short-and-medium wooden stick 9 of bark 8 screen out process.
In addition to the implementation; the present invention can also have other embodiments; for a person skilled in the art; the technical scheme that all employings are equal to replacement or equivalent transformation formation is easily expected, the technical scheme therefore adopting equivalent replacement or equivalent transformation to be formed all should drop in the scope of protection of present invention.
