1. A coating die head, comprising:
a coating main body comprising a first die head and a second die head arranged separately, the first die head and the second die head being spliced to define an accommodating cavity, and opposite ends of the coating main body being respectively provided with a coating inlet and a coating outlet which are in communication with the accommodating cavity; and
a turbulence assembly which defines a flow channel with a cavity wall of the accommodating cavity, the turbulence assembly being adjustably arranged in the accommodating cavity,
wherein the turbulence assembly comprises at least one turbulence structure, which is arranged in the accommodating cavity in such a manner that the number of the at least one turbulence structure in the turbulence assembly is adjustable and/or the at least one turbulence structure each has a variable shape and/or an adjustable position; and
wherein the at least one turbulence structure comprises two or more turbulence structures; and the two or more turbulence structures comprise a turbulence base and at least one turbulence stack block, the turbulence base being fixed in the accommodating cavity, and the at least one turbulence stack block being detachably connected to the turbulence base,
wherein the at least one turbulence stack block comprises a plurality of turbulence stack blocks, which are detachably connected to the turbulence base, and at least some of the plurality of turbulence stack blocks are located upstream and/or downstream of the turbulence base in a slurry movement direction.
