Powder accurate-weighing measurement feeding machine

Abstract

A powder feeder with accurate weighing and metering, comprising a weighing hopper, a spherical bucket, a feeding cylinder, a container, a feeding twin screw, a gear box, a geared motor, a weighing platform, and a bellows load cell, characterized in that: The weighing hopper includes a cover plate and a cone. The feeding port of the weighing hopper is set in the center of the cover plate. There are air holes on one side of the cover plate. The upper part of the cone is connected with the cover plate through a clamp, and the lower part of the cone is connected through The hoop and the upper part of the spherical bucket are connected as a whole, and the lower part of the spherical bucket is connected as a whole with the feeding cylinder through the clamp, and one end of the feeding cylinder is connected with the container, and the feeding twin-screw is arranged in the feeding cylinder and the spherical bucket. The invention is equipped with a horizontal stirring paddle, which eliminates the "bridging" phenomenon of materials in the weighing hopper during feeding, ensures the continuity of feeding, has excellent resistance to mechanical vibration interference, and makes the feeding of materials reach For the purpose of accurate metering and stable feeding, the relative error of continuous weighing and metering feeding is ≤0.1%.

Description

technical field [0001] The invention belongs to the technical field of machinery, and more specifically relates to a powder feeder with accurate weighing and metering. Background technique [0002] The disadvantages of the existing weighing feeder are: when feeding, the material in the weighing hopper will have a "bridging" phenomenon, resulting in feeding discontinuity; the anti-interference is poor, and the weighing hopper adopts a single Or two load cell supports, once mechanical vibration interference occurs, the weighing hopper will shake and seriously affect the measurement accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides an accurate weighing and metering feeder for powder materials, which is equipped with a horizontal stirring paddle, which eliminates the "bridging" phenomenon of materials in the weighing hopper during feeding, and ensures the continuity of feeding ; Use three bellows load cells to support t...
