Granule powder sieve vacuum feeding device

Abstract

The utility model discloses a granule powder sieve vacuum feeding device which comprises a box body, the inner top wall of the box body is fixedly connected with two hanging plates, the bottom end of each hanging plate is fixedly connected with a hanging ring, the inner walls of the two hanging rings are jointly and rotationally connected with a screening cylinder, a feeding pipe is embedded in the left side face of the box body, and a discharging pipe is embedded in the right side face of the box body. The left end of the feeding pipe is rotationally connected with the right end of the screening cylinder, and a motor is installed on the inner bottom wall of the box body. According to the device, through cooperation of the motor, the gear, the gear ring, the screening barrel and the spiral baffle, the motor works to drive the gear to rotate, the gear ring drives the screening barrel to rotate at a high speed, materials can be dispersed in the screening barrel, powder can be screened out, and particle materials can be left in the screening barrel and discharged; and meanwhile, the spiral baffle can block and guide the materials, the rotating speed of the materials in the screening cylinder is controlled, the materials are prevented from flowing too fast or nonuniformly, and the screening and feeding efficiency is further guaranteed.
