Solid material automatic weighing device and method

Abstract

The invention provides a solid material automatic weighing device and method. The solid material automatic weighing device comprises an outer box body with an opening on the top, a material supply box which is connected to the inner side wall of the outer box in a sliding manner and a material discharge box arranged under the material supply box; a pressure sensor is arranged at an opening where the outer box body is buckled with a sealing cover; the top of the material supply box is a material input port; the bottom of the material supply box is of a tunnel structure; the bottom of the tunnel structure is provided with a material discharge device; a material discharge guiding pipe is connected under the material discharge device; a motor is fixed inside the material discharge guiding pipe; the motor is used for driving the material discharge device to rotate; and the material discharge guiding pipe is contained inside the material discharge box. The solid material automatic weighing device is simple in structure, easy to maintain, small in volume, high in material discharge efficiency and accurate in controlling material discharge quantity and overcomes a problem that the prior art adopts a plastic container to roughly estimate and calculate the material weight and causes a big error the in material taking quantity. The solid material automatic weighing method is easy in operation.

Description

technical field [0001] The invention relates to the technical field of material measurement, in particular to an automatic weighing device and method for solid materials. Background technique [0002] With the continuous improvement of residents' economic income, people pay more and more attention to dietary health.
