Description

Technical Field

[0001] This application relates to the field of printing static eliminators, and particularly to a static eliminator for the paper receiving part of a printing device. Background Art

[0002] During the printing process of paper, friction is generated between the paper and the printing device, which will cause a large amount of static electricity to be generated on the paper. The static electricity on the paper will cause dust to adhere to the surface of the paper, thereby affecting the adhesion of ink during the printing process and reducing the printing quality. Therefore, it is necessary to perform a static elimination operation on the paper to improve the printing quality.

[0003] Currently, the common static elimination method in the printing industry is that a blower blows ions generated by an ion generator onto the surface of the paper, and the charged ions neutralize the static charges on the surface of the paper. However, the existing static eliminator has the problem of uneven ion distribution during the working process, which leads to low static elimination efficiency. When the paper passes through the static eliminator, it may shake or bend, which also reduces the static elimination efficiency.

[0004] Regarding the above related technologies, the inventor believes that the existing static eliminator has the problem of low static elimination efficiency. Utility Model Content

[0008] By adopting the above technical solution, the driving component drives the guiding roller to rotate, the guiding roller conveys the paper, and the flattening mechanism flattens the paper during the conveying process, thereby reducing the phenomenon of the paper shaking or bending. The ion wind generated by the combined action of the blower and the ion generator passes through the first flow equalizing component and the second flow equalizing component to simultaneously remove static electricity from the upper and lower surfaces of the paper, thereby improving the efficiency of static electricity removal from the paper.

[0013] Preferably, the diameter of the second air outlet pipe close to the second connecting pipe is smaller than the diameter of the second air outlet pipe far from the second connecting pipe.

[0014] By adopting the above technical solution, the resistance of the ion wind passing through the second air outlet pipe with a smaller diameter is larger, and the resistance of the ion wind passing through the second air outlet pipe with a larger diameter is smaller, which is beneficial to the discharge of the ion wind from the second air outlet pipe far from the second connecting pipe, thereby improving the flow equalizing effect of the second flow equalizing component and improving the efficiency of static electricity removal from the paper surface.
