In order to achieve continuous processing, a material transfer bin is generally used to transfer materials, which is convenient for replacement and continuous processing. In addition to the discharge port connected to the negative pressure conveying structure, the material transfer bin also has a sealing top cover for the material adding port to prevent impurities from mixing into the material. However, in daily use, due to the high overall height of the transfer bin, it is not easy for operators to see the situation of the material adding port on the top of the transfer bin, so they often forget to open the sealing top cover.
