Spiral micro-weighing scale

The utility model relates to a spiral micro-weighing scale capable of accurately measuring and continuous controlling materials and aims to solve the problem of micro-batching. The spiral micro-weighing scale is composed of a bracket, a weighing chamber, a material inlet, a material outlet, a motor, a frequency converter, a weighing sensor, a speed sensor, a control instrument, an electrical control cabinet and a micro-unloading device. The micro-unloading device includes shifting rods, a screw, spiral blades and a cylinder. The spiral micro-weighing scale has the advantages of reliable and accurate weighing, continuous and stable material feeding, high reliability and long service life, emission is carried out without residue, waste is reduced, and the consistency of mixtures is improved.
