Abstract

The invention relates to a rolling mechanism for a lithium battery diaphragm. The invention relates to a diaphragm cutting device of cell packaging machinery. The rolling mechanism comprises a transmission device for operation of the device, a frictional plate which provides a frictional force and a hobbing cutter mechanism which cuts the diaphragm. The rolling mechanism driven by the transmission device makes the hobbing cutter mechanism be rubbed with the frictional plate so as to drive the hobbing cutter mechanism to cut the diaphragm. The rolling mechanism provided by the invention is simple in structure, and the diaphragm is completely and effectively cut, and waste brought by material loss is saved.

Description

technical field [0001] The invention relates to a film cutting device of a cell packaging machine, in particular to a cutting device for lithium battery separators and various new separators. Background technique [0002] At present, in the structure of lithium batteries, the diaphragm is one of the key inner components. If the diaphragm is broken, a short circuit will occur and the yield will be reduced. In the lithium battery industry, in the past, the diaphragm was cut by cutting with a blade. Due to the performance of the diaphragm required for lithium batteries, the lateral strength of the diaphragm cannot be too large, and when the diaphragm is cut in the process of diaphragm processing, battery assembly, etc., most of the diaphragms are cut along the transverse direction, resulting in the cutting method of cutting with a blade. The diaphragm is prone to rupture. cause huge waste. Secondly, the blade is generally manually operated, and the work efficiency is not high...
