Post-treatment mechanism for textile fabric production process

The post-processing mechanism for the textile fabric production process comprises an operation table and a flat screen printing machine body, a scraper is slidably connected to the inner wall of the flat screen printing machine body, and a coating collecting groove is formed in the side, away from the scraper, of the inner wall of the flat screen printing machine body; a connecting rod is inserted into the inner wall of the coating collecting tank, and one end of the connecting rod is fixedly connected with a push plate. Through the arrangement of the spraying mechanism, a piston is driven to extrude a piston barrel in the driving process of the driving mechanism, and then air is supplied to a first hose, so that an extrusion plate extrudes a coating storage bin; and when reset is carried out after spraying, air in the inflation belt is evacuated, the extrusion plate is reset, then negative pressure is generated in the coating storage bin, the coating storage bin is filled with the negative pressure, and use
