Abstract

The invention relates to a mould head gasket for an extrusion coater, an extrusion mould head and an extrusion coater. The mould head gasket comprises a left side gasket and a right side gasket, and further comprises a distribution gasket positioned between the left side gasket and the right side gasket, wherein gasket distribution holes are separately formed between two side surfaces of the distribution gasket and the corresponding side surfaces of the corresponding side gaskets; or the mould head gasket further comprises at least two distribution gaskets positioned between the left side gasket and the right side gasket, wherein the gasket distribution holes are separately formed between opposite side surfaces of adjacent distribution gaskets, and between corresponding side surface of the distribution gasket at outer edge and the corresponding side surfaces of the corresponding side gaskets. The mould head gasket for extrusion coater provided by the invention can realize multi-amplitude continuous coating, so that zebra distribution type pole pieces with coating areas and blank areas, which are arranged in a spaced manner in a direction perpendicular to a current collector, are obtained, and the blank areas are automatically reserved for welding lug plates, and therefore, quality and production efficiency of the pole pieces are improved.

Description

technical field [0001] The invention belongs to the field of extrusion coaters, and in particular relates to a gasket for an extrusion coater, an extrusion die head and an extrusion coater. Background technique [0002] In the process of producing lithium-ion batteries, the coating of pole pieces is an essential process, and it is also a key process that directly affects various performances such as battery safety, capacity and consistency. At present, there are two commonly used pole piece coating methods: transfer coating and extrusion coating. The structure of the transfer coating equipment is complicated, and the debugging is cumbersome; while the extrusion coating machine has a simple structure, compact equipment, and convenient debugging. It can be used for coating of higher viscosity fluids and can obtain higher-precision coatings; It has gradually become one of the mainstream coating technologies. [0003] The patent with notification number CN205146588U discloses ...
