Powder feeding mechanism and operation method of functional gradient powder material

Abstract

The invention discloses a functional gradient powder material feeding mechanism and an operation method. Two cylinder body fixing pieces are fixedly connected with the left side of a bottom board device of the mechanism through bolts; the cylinder body fixing pieces are used for fixing a cylinder body assembly to the bottom board device of the mechanism in an interference fit manner; a left limiting copper post is fixedly connected with the middle of the bottom board device of the mechanism; a transmission mechanism is fixedly connected with the right side of the bottom board device of the mechanism through a bolt; the transmission mechanism is connected with a sliding block in a cylinder through a threaded rod; the upper portion of the cylinder body assembly is connected with an upper supporting board in a clearance fit manner; the cylinder body assembly is fixedly connected between a supporting board and the bottom board device through four copper posts; a powder material storage bin is mounted at the upper portion of the supporting board; and the powder material storage bin is composed of a first stepping motor, a powder material barrel and a stirrer. The powder feeding mechanism can convey functional gradient powder materials accurately through back and forth movement of the transmission mechanism, intermittent rotation of the stirrer and air injection of an air pump.

Description

technical field [0001] The invention relates to a functional gradient powder material feeding mechanism and an operation method, in particular to a functional gradient material powder feeder capable of quantitatively and accurately transporting fine powder materials to designated areas. The combination of traditional mechanical devices and modern infrared sensors further improves the precision of the powder feeding mechanism. Background technique [0002] Functionally graded material is a new type of composite material developed to meet the needs of new materials in high-tech fields and to meet the continuous and repeated work in extreme environments. In the manufacture of functionally graded materials, the delivery methods of powders of different components mainly include preset method and synchronous powder feeding method. The existing conveying devices mainly include direct gravity type, scraper type, screw type and drum type. The direct gravity powder feeding device co...

Problems solved by technology

The direct gravity powder feeding device controls the powder output by controlling the opening size of the lower end of the powder storage bin. This method is not easy to control the powder feeding amount and cannot accurately control the powder output; the scraper type powder feeding device uses a scraper to discharge powder gradually. Large, complex structure and a large powder bin during the transportation process, which is easy to cause integral phenomenon

[0003] At present, most of the existing powder feeders require the powder to be conveyed to have good fluidity, or it is difficult to ensure the powder conveying accuracy, or it is easy to block the outlet
