The printer further includes: the guard board air duct 1 is transversely fixed in front of the pipeline box 2; the first holes on the guard plate air channel 1 are uniformly arranged on the surface of the guard plate air channel 1 along the transverse direction, and the first holes on the guard plate air channel 1 are only arranged on the upper surface and the lower surface of the guard plate air channel 1.
A plurality of first holes are transversely and uniformly arranged on the guard board air duct 1 and are used for improving the cleaning effect on the surface of paper. Only a plurality of first holes are formed in the upper surface and the lower surface of the guard board air duct 1, so that the guard board air duct 1 can achieve a stronger cleaning effect on the surface of paper and the space below the guard board air duct 1.
The working process of the invention is as follows: when the printer works, after the paper is printed, the paper is sequentially conveyed to a paper outlet through the paper conveying roller 3, the roller air duct 4, the guide plate, the paper outlet roller and the guard board air duct 1. The drum air duct 4 rotates, and the rubber surface 41 on the surface thereof cooperates with the paper transfer roller 3 to transfer the paper. A rubber surface 41 is provided on the surface of the roller duct 4 to increase friction between the roller duct 4 and the paper, thereby preventing the paper from sliding. And finally, the paper is conveyed out of the paper outlet and enters the outside through the guiding of the guide plate and the conveying of the paper outlet roller. The first fan 52 and the second fan 42 are started to generate negative pressure at the guard board air duct 1 and the roller air duct 4, and external air enters the printer from the paper outlet and flows to the guard board air duct 1 and the roller air duct 4 respectively. A plurality of second fans 42 are transversely arranged in the roller air duct 4 and are used for compensating air pressure, so that the roller air duct can clean dust on the surface of paper to achieve a required effect. The second fan 42 pushes more airflow to the side under the cooperation of the inner wall of the roller air duct 4, so as to improve the air suction effect of the roller air duct 4. The air flowing in from the paper outlet can prevent dust generated by the printer from leaking into the outside air. The air flow flowing to the roller duct 4 will clean the side of the paper with the writing or pattern and the dust inside the printer, and then carry the dust into the roller duct 4. The air flow flowing to the guard board air duct 1 can clean the back surface of the paper, and then carry dust into the guard board air duct 1.
The air flow carrying dust in the roller air duct 4 sequentially passes through the roller air duct 4, the first air vents 43 and the second air vents 21 and enters the dust removing chamber 6 through the pipeline. The air flow carrying dust in the guard plate air duct 1 enters the dust removing chamber 6 through a pipeline. The air flow carrying dust is decelerated under the action of the deceleration surface 61 arranged in the dust chamber 6, so as to improve the filtering effect of the filter screen on the dust, and then enters the installation box 5 through the vent arranged in the center of the limiting plate 62. Dust in the air flow is filtered by a filter net 51 provided inside the installation box 5 and finally discharged to the outside air. The limiting plate 62 is arranged outside the deceleration surface 61, so that the installation box 5 can be prevented from damaging the deceleration surface 61, unfiltered air can be prevented from leaking into the outside air through gaps between the sliding blocks 54, and pollution is caused to the outside air.
When the filter screen 51 needs to be replaced, the installation box 5 is slidably installed, the installation box 5 is taken out of the dust removal chamber 6, the filter screen 51 is replaced, and the rough surface arranged on the inner wall of the outer side of the installation box enables sliding to be more convenient. When repair of the first fan 52 is required, the first fan 52 is slid, and the first fan 52 is taken out of the mounting box 5.
The above-described embodiments are only some embodiments, but not all embodiments, of the present invention, and other embodiments, which are obtained by those skilled in the art without any inventive effort, are within the scope of the present invention.
