1. A coating die head, comprising:
a die head body, a material cavity being arranged in the die head body, and a first wall surface of the material cavity having a through hole;
at least one cavity pressure adjusting block, the at least one cavity pressure adjusting block being arranged in the material cavity, the at least one cavity pressure adjusting block internally comprising a cavity, the at least one cavity pressure adjusting block being configured to change a volume with a pressure change of the cavity, one side wall surface of the at least one cavity pressure adjusting block facing towards the first wall surface being a second wall surface, and the second wall surface being fitted with the first wall surface and surrounding a region where the through hole is located;
a regulating assembly, the regulating assembly comprising at least one pressure regulator and at least one flow channel tube, the at least one pressure regulator being arranged on the at least one flow channel tube, the at least one flow channel tube hole in a penetrating manner and communicates with the cavity through the through hole, the at least one pressure regulator being used for conveying liquid fluid into the cavity or extracting liquid fluid from the cavity and adjusting the volume of the at least one cavity pressure adjusting block by changing an internal pressure of the cavity; and
a detection apparatus electrically connected to the regulating assembly and comprising at least one pressure sensor, wherein the at least one pressure sensor is installed on the at least one cavity pressure adjusting block, and a sensing head of the pressure sensor is exposed to the material cavity, the regulating assembly performs a corresponding adjustment of the volume of the at least one cavity pressure adjusting block according to the pressure of the material cavity detected by the pressure sensor.
