At present, glass liquid required by glass fiber tank furnace wire drawing is formed by melting batch materials in a tank furnace at high temperature. The batch is formed by mixing a plurality of powder materials according to the set weight. In order to ensure the uniformity of the batch prepared by mixing different powder materials, the powder materials are dried and ground into particles with the size of 200-325 meshes, and then the particles are sent into a bin arranged at the highest position of a batching system for temporary storage by compressed air. At present, the powder weighing operation in the industry is generally carried out by means of a bucket-shaped scale. When the powder is weighed, the powder falls into a screw feeder arranged above the bucket-shaped scale by self gravity, the bucket-shaped scale is fed in a screw feeding mode, and the weight is measured by a pressure sensor arranged at the lower part of the bucket-shaped scale. In order to achieve both the weighing speed and the weighing precision, the screw feeder is generally designed into a double-layer screw type, namely, a thick main screw is arranged on the upper layer, and a thin auxiliary screw is arranged right below the main screw in parallel. When the weighing operation is carried out, the main screw is responsible for quick feeding, and when the weight of the powder is close to a set value, the main screw stops rotating, and the auxiliary screw continues rotating until the set value is reached. In the process of main spiral rotation, a large amount of gas is mixed in the powder due to rapid and massive feeding, so that the scale body shakes and the weight reading is unstable. The existing design adopts a dust remover to suck and discharge gas, so that the scale body is easy to float upwards, and the swinging and reading of the scale body are further aggravated. In the process of weighing, the batching system can be repeatedly suspended so as to be convenient for accurate reading, so that a lot of waiting time is consumed, and meanwhile, the weighing precision is also adversely affected.
