Description

Technical Field

[0001] The invention relates to a feeding device, in particular to a secondary feeding device for a grading system. Background Art

[0002] Toner, also called carbon powder, is a powdered substance used in laser printers to form images on paper. Black toner is composed of binder resin, carbon black, charge control agent, external additives and other ingredients. Color toner also needs to add pigments of other colors. In the prior art, the processing and production of toner usually requires secondary feeding of raw materials. Therefore, if the raw material particles are large during feeding, it will easily affect the quality of the finished toner. The finer the toner, the better. Since the grading and crushing process is carried out in a barrel, it is impossible to determine whether there is an abnormality in the grading device. When a batch of products is completed, the production abnormality is discovered, and rework will seriously affect the progress of the work. Therefore, an observation window is needed to observe the output of the graded feeding bin. However, during the observation process, the toner is easily adhered to the observation window, affecting the observation effect. Summary of the invention
