Now more and more information on the market is recorded on paper by printing machines.

[0003] In the prior art, there will be uncleaned dust on the surface of paper before it enters the printing equipment. The dust will cause the printed product to have unclear printing display problems, so a group of dust removal rollers are usually set on the surface of the printing equipment. The dust removal rollers effectively clean the surface of the object through their unique mechanical principles, surface characteristics, and electrostatic adsorption of dust removal silicone rollers, fiber capture and cleaning processes.
