The brush roller assembly 12 is rotatably installed in the exhaust hood assembly 11 and has an antistatic function, effectively preventing the adsorption of dust and thus greatly improving the dust removal effect. The lifting assembly 13 is connected to the exhaust hood assembly 11 by transmission, and drives the exhaust hood assembly 11 to move relative to the brush roller assembly 12, thereby facilitating the inspection and maintenance of the brush roller assembly 12.
[0029] Please see Figures 1-4 As shown, in this embodiment, the exhaust hood assembly 11 includes an exhaust hood body 111, a connecting hood 112, and an exhaust connecting pipe 113.

[0035] This utility model discloses a flexographic printing machine including the antistatic dust removal mechanism 10 described above.
[0036] It should be noted that the specific working process of the antistatic dust removal mechanism and flexographic printing machine of this utility model is as follows: the drive structure 121 drives the rotating shaft structure 122 to rotate, and the brush roller body 123 rotates in the receiving cavity 1122 following the rotation of the rotating shaft structure 122. Since the brush roller body 123 is made of antistatic material, it will not generate static electricity to attract dust. The exhaust fan sequentially extracts the dust cleaned by the brush roller body 123 in the connecting hood 112 through the connecting pipe 113 and the exhaust hood body 111, thereby realizing the dust removal operation; at the same time, the lifting component 13 can drive the exhaust hood component 11 to move away from the brush roller component 12, thereby facilitating the inspection or maintenance of the brush roller component 12.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
