Abstract: Provided are an air outlet apparatus and a drying device. The air outlet apparatus includes: a housing provided with a first cavity and an air inlet and an air outlet communicated with the first cavity; and a wind speed adjusting assembly, where the first cavity is provided with a plurality of wind speed adjusting assemblies distributed in a first direction, such that the first cavity is divided into a plurality of air outlet sections distributed in the first direction by the wind speed adjusting assembly; and where each of the wind speed adjusting assemblies is configured to open or close at least some air outlets, so as to adjust outlet wind speed of each of the air outlet sections. The drying device includes the above air outlet apparatus.

Abstract: A coating die head and a coating apparatus including one are provided. The coating die head includes a first die head and a second die head. The first die head includes a first die head body and multiple first lip modules, and the first lip modules are spliced sequentially along a first direction. Each of the first lip modules is detachably connected to the first die head body, each of the first lip modules is provided with a first groove, the first grooves of the plurality of first lip modules are spliced to form a main chamber for storing a slurry, and the first direction is a length direction of the main chamber. In the coating die head, the first lip modules may be replaced or recombined to change the length of the main chamber so that the coating die head is suitable for producing electrode plates with different widths.
