Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a paper suction mechanism of a printing machine comprises a suspension rod 1, a positioning shaft 2 which is axially and uniformly distributed is arranged on the suspension rod 1, a containing cavity 11 which is circumferentially distributed is formed in the suspension rod 1, a worm 3 is rotatably connected in the containing cavity 11, two ends of the worm 3 are connected with the suspension rod 1 through bearings, a positioning sleeve 12 is fixedly arranged on the outer surface wall of the suspension rod 1, the positioning shaft 2 penetrates through the positioning sleeve 12 and is in up-and-down sliding fit, a sliding groove 122 is formed in the inner surface wall of the positioning sleeve 12 and is close to one end, a sliding block 22 which is matched with the sliding groove 122 is welded on the outer surface wall of the positioning shaft 2 and is close to one end, an annular cavity 121 is formed in the positioning sleeve 12, the annular cavity 121 is communicated with a cavity where the worm 3 is located in the suspension rod 1, a worm wheel 4 which is meshed with the worm 3 is rotatably connected in the annular cavity, the worm wheel 4 and the positioning shaft 2 penetrate through the screwing matching, and the worm wheel 4 rotates to drive the positioning shaft 2 to slide up and down in the positioning sleeve 12 through the screwing effect.
