Technical Field

[0001] The utility model relates to the field of feeding equipment, in particular to a spiral weighing feeding structure. Background Art

[0002] With the rapid development of modern industrial production, the requirements for material conveying and metering are increasing. Especially in industries such as chemicals, cement, and lime, the precise conveying and metering of powdered and granular materials has become a critical step in the production process. As a device that integrates feeding, metering, and conveying, the importance of the screw weigh feeder is becoming increasingly prominent.

[0003] In the existing technology, screw conveyors are mainly used for transporting materials. During the transportation process, due to the lack of a measuring and weighing structure, the weight of the materials cannot be accurately measured during the transportation process, which affects cement production and reduces production efficiency. At the same time, during the transportation of materials, the material only relies on the screw conveyor for transportation, and the fluidity of the material is insufficient, which makes it easy for the material to remain in the conveying pipe and easily cause blockage.

[0004] Therefore, we made improvements to this and proposed a spiral weighing feeding structure. Utility Model Content
