Combined moving type powder feeder

Abstract

The invention discloses a combined moving type powder feeder. The combined moving type powder feeder comprises an impeller shaft, a barrel body, a powder bucket, a slide block and a turntable. When the combined moving type powder feeder works, the air tightness of the barrel body is kept, and powder fed into the powder bucket is scattered through a stirring rod, thus preventing the powder from forming an arched structure in the powder bucket; a spiral impeller at the bottom part of the impeller shaft can reversely rotate at the set speed to push the powder; the powder can enter a powder groove in the turntable through a powder falling tube and the power groove is gradually filled; the powder in the powder groove is leveled through the slide block; the turntable can rotate along with a main transmission shaft, so that the powder in the powder groove can be rotated to arrive at a powder inlet of a powder discharging tube and then is sucked off through the powder discharging tube, and the powder feeding process is finished. According to the combined moving type powder feeder, the rotating speed ratio K of the turntable plate to the impeller shaft can be accurately controlled, so that the uniformity of powder feeding quantity can be maintained. The combined moving type powder feeding manner that the spiral impeller is used for impelling and the turntable is used for sucking is adopted and particularly suitable for the powder with low flowablity or without flowablity; with the adoption of the aforementioned combined moving manner, the powder feeding quantity uniformity can be ensured, and the powder can be continuously adjustably fed.

Description

technical field [0001] The invention belongs to the technical field of laser material processing and advanced manufacturing, and specifically relates to a composite motion powder feeder, which is especially suitable for automatic powder feeding of powders with poor fluidity or no fluidity, and can meet the needs of laser cladding and laser three-dimensional manufacturing technology . Background technique [0002] Laser cladding technology has been widely used in metallurgy, machinery, aviation, aerospace and other fields, and laser cladding powder feeder is the key equipment. At present, there are many types of automatic powder feeders used at home and abroad, including: scraping Suction type, scraper type, spiral type, drum type, capillary type, pneumatic type, etc. Although the above-mentioned different types of powder feeders have their own characteristics, they all have different degrees of problems in feeding fine powder, aluminum powder, and alumina powder with poor f...
