Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm production, in particular to an automatic feeding device for lithium battery diaphragm production. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. Diaphragms with excellent performance play an important role in improving the comprehensive performance of the battery. The production of lithium battery diaphragms requires the mixed production of multiple different raw materials. Usually, these raw materials need to be mixed to obtain the final diaphragm product.

[0003] When stirring the raw materials, the raw materials are usually placed inside a material box and then supplied to the inside of a mixing box through the material box. However, during the supply process, the supply output pipe is usually fixed, which makes it impossible to move the output pipe, so that the output pipe always supplies the material at the same place and cannot supply the material evenly. At the same time, the existing stirring mechanism usually only uses a single stirring rod for stirring, and the mixing box cannot rotate and cooperate, resulting in a slow stirring rate and an inability to quickly complete the stirring and mixing of the raw materials.
