Wherein, crack of selecting materials is made up of two parallel guide rails, and the distance of selecting materials between crack is less than the width of material with card convex side, is greater than the width of the other side of material, material is hung over wherein on a parallel guide rail with one end of card convex, and one end enters and selects materials in crack in addition;
Guide rail is extended by the wherein parallel guide rail of and forms.
Wherein, guide rail is extended laterally by crack of selecting materials.
Wherein, crack of selecting materials is connected with discharging track, and the junction of select materials crack and discharging track is provided with guide rail, and discharging track is arranged at the below of guide rail.
Wherein, track of selecting materials is set to two.
Wherein, select materials above crack and described discharging track and be equipped with the backgauge bar preventing material from dropping out.
Wherein, track of selecting materials gradually excessively is inclination to crevice place of selecting materials by level from stop gauge is excessively vertical more gradually.
Compared with prior art, the beneficial effect of the application is:
A kind of automatic screening feeding device described in the application, comprise hopper, material loading track, to select materials track and discharging track, hopper is used for blowing and collects the material dropped from material loading track and track of selecting materials, material loading track rises along hopper spiral inner wall, continue to track supply material of selecting materials, the end of material loading track is provided with the track of selecting materials of some, the select materials end of track of every bar is equipped with discharging track, many track of selecting materials runs simultaneously, enhance productivity, track of selecting materials is provided with the stop gauge preventing material stacking successively, by the material be stacked, or tilted-putted material screen single flat of hanking arranges the material of row, partial material drops back hopper, tangle the crack of selecting materials of card convex material upwards, the material vertically rear superposed material of card convex is out screened, unclassified stores drops back hopper, drop the guide rail of reverse material, guide rail is extended by the wherein parallel guide rail of and forms, after previous step screening, card convex is towards there being both direction, one towards material to be guided by guide rail and to drop back hopper, another one towards material be the material that finishing screen is selected, the problem of screening is arranged before which solving tiny material Automated assembly, the Automated assembly of tiny parts is made to become possibility, assembly precision is improve while improve production efficiency greatly.

Detailed description of the invention
Be described below in conjunction with the preferred embodiment of accompanying drawing to the application, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the application, and be not used in restriction the application.
As shown in Figure 1 to Figure 3, a kind of automatic screening feeding device described in the application, the material 9 screened is the granule materials 9 of sheet, and the top injection mo(u)lding of material 9 one side has card convex 10, and it comprises hopper 1, material loading track 2, select materials track 3 and discharging track 4.Hopper 1 is for blowing and collect the material 9 dropped from material loading track 2 and track 3 of selecting materials, and during material loading, hopper 1 directly put into by material 9.Material loading track 2 rises along hopper 1 spiral inner wall, and the end of material loading track 2 is provided with two tracks 3 of selecting materials, and the select materials end of track 3 of every bar is equipped with discharging track 4.As shown in Figure 2, track 3 of selecting materials is provided with the stop gauge 5 preventing material 9 stacking successively, and stop gauge 5 is for being parallel to the blend stop of track 3 of selecting materials, and the material 9 of the material 9 be stacked or inclination is paved by blend stop, unnecessary material 9 is pushed open, and drops in back hopper 1.Crack 6 of selecting materials tangles card convex 10 material 9 upwards, and guide rail 7 drops reverse material 9.Guide rail 7 is extended by the wherein parallel guide rail of and forms.Track 3 of selecting materials gradually excessively is inclination to crack 6 of selecting materials by level from stop gauge 5 is excessively vertical more gradually.After stop gauge 5, being laid in the material 9 of selecting materials on track 3 side by side along with the inclination of track 3 of selecting materials becomes vertical direction by tiling gradually, and drops in crack 6 of selecting materials.As shown in Figure 2 and Figure 3, crack 6 of selecting materials is made up of two parallel guide rails, the distance of selecting materials between crack 6 is less than the width of material 9 with card convex 10 side, be greater than the width of the other side of material 9, material 9 is hung over wherein on a parallel guide rail with one end of card convex 10, and one end enters and selects materials in crack 6 in addition.Vertically, card convex 10 to drop back hopper 1 towards non-material 9 upward, and guide rail 7 is extended laterally by crack 6 of selecting materials.Side guided into by the material 9 card convex 10 being hung over this guide rail 7, and the back hopper 1 that finally drops.Crack 6 of selecting materials is connected with discharging track 4, and crack 6 of selecting materials is provided with guide rail 7 with the junction of discharging track 4, and discharging track 4 is arranged at the below of guide rail 7.Namely hopper 1 led back to by the directed track 7 of the material 9 that poor direction is true, and material 9 in the right direction enters discharging track 4.Select materials above crack 6 and described discharging track 4 and be equipped with the backgauge bar 8 preventing material 9 from dropping out.
Last it is noted that these are only the preferred embodiment of the application; be not limited to the application; although with reference to embodiment to present application has been detailed description; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but within all spirit in the application and principle; any amendment of doing, equivalent replacement, improvement etc., within the protection domain that all should be included in the application.
