Specific embodiment
It is described in further detail below in conjunction with content of the drawings and specific embodiments to the utility model.
Gravity powder feeder provided by the utility model is by the metal powder in barrel 10 since gravity drops down onto turntable 2
On, then be driven by a motor rotation to funnel 6 out and it is preset on the surface of the workpiece.Demarcation plate 9, demarcation plate 9 are equipped in barrel 10
Metal powder in barrel 10 is divided into upper layer and lower layer, solves what Gravity changer during powder feeding generated powder feeder stability
It influences.Blanking funnel 8, blanking mouth 4 in powder feeder during metal powder gravity fall go out funnel 6 and turntable 2 is all made of
Brass material production, avoiding leads to the problem of gluing powder since metal powder itself has magnetic, improves the essence of powder feeder
Degree.
Gravity powder feeder as shown in Figure 1, Figure 2, Figure 3 shows, including barrel 10, barrel lid 11, blanking funnel 8, demarcation plate 9,
