By servomotor, drive unit adds that planetary reducer forms, be connected with powder feeding wheel at speed reducer output shaft end, and the outer round surface of powder feeding wheel, near containing the outlet of powder powder bucket, drives powder feeding wheel to rotate by electric machine rotation step-down gear reduction of speed, realizes powder supplies.
Powder outlet device is arranged on powder conveyer bottom, and powder outlet device inside is vertebral body structure and is provided with the powder road of certain angle, and the outlet in powder road is connected with snubber assembly, and the meal outlet bottom snubber assembly is connected with powder-feeding mouth.
Compared with prior art, the invention has the beneficial effects as follows: structure is simple, easy to operate, powder conveying continuous uniform, rate of powder are controlled, the output of powder end has buffering, namely.
(1) this powder conveyer structure is simple, is divided into five parts: contain powder powder bucket, drive unit, powder feeding wheel and end snubber assembly.Contain the metal-powder of powder powder bucket enough consumptions of splendid attire in advance, contain powder powder bucket adjustable up and down, realize regulating powder output flow with the spacing of powder feeding wheel by the outlet of adjustment powder bucket; Drive unit has deceleration part and motor part, and high reduction ratio step-down gear coordinates servo electrical machinery system to drive powder feeding wheel guarantee rate of powder uniform and stable, regulates powder feed rate by changing motor speed simultaneously; End snubber assembly is mounted in powder conveying terminal position, and be provided with the powder road of certain angle in device, exit connects powder-feeding mouth.
(2) this powder conveyer powder carries continuous uniform, rate of powder controlled: adopt private to take motor and coordinate high reduction ratio planetary reducer control powder feeding wheel speed adjustment powder feed rate to regulate by regulating the spacing of the outlet of powder bucket and powder feeding wheel to realize unit time rate of powder simultaneously, control powder output flow, ensure even, smooth, the stable supply of powder.
(3) powder end output buffer: the powder of output flows to end snubber assembly through powder conveying pipe, powder flows to laser melting coating molten bath by powder-feeding mouth after buffering.
