A drying mechanism of a flexographic printing machine comprises a conveyor belt 1, a first support frame 2 is installed at the discharge end of the conveyor belt 1, a stainless steel table 201 is fixedly connected to the top of the first support frame 2, a support plate 202 is fixedly connected to the inside of the first support frame 2, and a second support frame 3 is installed at the end of the first support frame 2 away from the conveyor belt 1; an air outlet assembly is installed on the top of the stainless steel table 201, and the air outlet assembly is used to blow dry the ink on the paper; a cooling assembly is installed on the top of the support plate 202, and the cooling assembly is used to cool the ink on the paper; a collecting assembly is installed on the top of the second support frame 3, and the collecting assembly is used to collect the printed paper.

[0026] When in use, the printed paper is conveyed to the top of the stainless steel table 201 through the conveyor belt 1, and then the ink on the paper is cooled by the cooling component, and the ink is blown dry by the wind generated by the air outlet component, and finally the paper is rolled up by the collecting component.

[0027] The air outlet assembly includes a side air outlet block 4, an upper air outlet block 401 and an air outlet duct 402. Two symmetrically distributed side air outlet blocks 4 are installed on both sides of the top of the stainless steel table top 201, and two symmetrically distributed upper air outlet blocks 401 are installed on the top of the two side air outlet blocks 4. Air outlet ducts 402 are installed on the top of the two side air outlet blocks 4 and the two upper air outlet blocks 401.
