Description

Technical Field

[0001] The utility model relates to the field of feeding and conveying equipment, in particular to an automatic vibration feeding and conveying system for a lithium iron phosphate production line. Background Art

[0002] Lithium-ion batteries have the advantages of high energy, long life, and low pollution. They are widely used in many fields such as mobile phones, computers, electric bicycles, and electric vehicles. Lithium iron phosphate positive electrode materials are an important component of lithium-ion batteries. Lithium iron phosphate positive electrode materials are generally prepared by high-temperature solid-phase synthesis. The processes involved are mixing, drying, sintering, crushing and grading, and packaging.

[0003] A screw feeder is required in the production line of lithium iron phosphate positive electrode materials. The rotating motion of the screw is used to transport the material from the bottom of the container or the storage bin to the target location. The feeding is achieved by pushing the material with the screw. Existing screw feeders may cause material damage during transportation, especially when the material is squeezed between the spiral blades and the conveying pipe. Materials with high humidity or sticky materials are easy to accumulate inside the spiral blades or conveying pipes, causing blockage, and subsequent cleaning and sanitation maintenance are relatively difficult.
