Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production equipment, in particular to an extrusion coating split gasket. Background Art

[0002] The coating process of lithium batteries is squeezed in the press coating process. The width, thickness, uniformity and edge thinning of the coating are closely related to the coating gasket. In the actual production process, affected by the properties of the slurry and the needs of subsequent processes, the width and edge thinning of the coating need to be adjusted. The adjustment range of the inherent gasket is limited. If the adjustment range of the current gasket is exceeded, it is necessary to reprocess and purchase a new gasket. According to market conditions, the processing and transportation time of a gasket is at least one week, and the cost is about one thousand yuan. In the early stage of product changeover, the gasket width and edge chamfering tests are repeated, and the replacement cost is extremely high at this time. Utility Model Content
