Accurate quantitative spiral powder material feeding device

Abstract

The invention is suitable for the technical field of analysis and measurement control, and particularly relates to an accurate quantitative spiral powder material feeding device which comprises a device body shell. A material storage structure is arranged in the device main body shell, and the material storage structure is used for storing materials; the material storage structure is communicated with a discharging structure, and a sensor arranged on the discharging structure is used for sensing the quality of discharged materials; the material storage structure is divided into a plurality of small grids which are spirally staggered, a plurality of poking pieces matched with the small grids are arranged in the material storage structure, the poking pieces are pressed through elastic structures, and when the poking pieces are pressed along with the elastic structures, the poking pieces can push the staggered small grids open at a time from bottom to top to form a door, so that materials in the small grids slide into the discharging structure; the sensor arranged on the discharging structure is used for sensing the discharging quality, accurate quantitative feeding is achieved, and the high requirement for the thickness of material particles can be met; and moisture absorption of materials is avoided to the greatest extent, overall cleaning is convenient, mutual pollution of different materials is avoided, and the non-corrosive requirement is met.

Description

technical field [0001] The invention relates to the technical field of analysis and measurement control, in particular to a precise quantitative screw type powder material feeding device. Background technique [0002] Accurate quantification is required during the material preparation process and the testing process, and the commonly used methods are medicine spoons and balances; [0003] A medicine spoon is a tool for taking powdery or small granular solid reagents. Most medicine spoons have only one spoon, usually made of metal, horn, or plastic; [0004] A balance, a weighing instrument. The balance beam is supported by the fulcrum at the center of the beam to form two arms, and a plate is hung on each arm, one of which contains an object of known mass, and the other plate contains an object to be measured, which is fixed on the beam. The deflection of the pointer when it does not swing and points to the middle scale indicates the quality of the object to be measured. ...
