Abstract
The invention relates to a paper-feeder with dust-cleaning function, which comprises paper-feeding roller, dust collector and brush set. The paper-feeding roller is used for feeding paper passing paper path. The dust collector is set at one side of the wheel, and has a adhesive layer to collect and stick the wastepaper and dust on the wheel to avoid the wastepaper and dust being coiled back to the paper path. The brush set contacts the roller to remove the wastepaper and dust on the roller into the dust collector.
Description
Technical field
The present invention relates to a kind of paper conveying apparatus with dedusting function, relate in particular to a kind of adhesion layer that utilizes and adsorb paper scrap and dust, reach the paper conveying apparatus of dust removing effects whereby in mode cheaply, paper conveying apparatus of the present invention is applicable to document handling apparatus, as scanner, duplicator, printer and multifunctional paper feeding machine etc.
Background technology
Roller on traditional automatic paper conveying apparatus, major part all do not have the design of dedusting, though some has the design of control of dust, just utilize a dust-collecting box to collect paper scrap and dust usually.Yet, if the faster rotational speed of roller, be collected in paper scrap in the dust-collecting box and dust and be easy to be rotated air-flow and roll and get back in the paper-feeding channel, and then influence scanning quality or print quality, this causes under at present for the more and more higher trend of the requirement of paper feed speed very easily.Perhaps, paper scrap in the dust-collecting box and dust also easily because the carrying of automatic paper conveying apparatus is moved and got back in the paper-feeding channel, influence scanning or print quality equally.
The TaiWan, China patent gazette discloses a kind of paper feed dust arrester No. 563627, and it utilize to be blown and air-breathing mechanism blows off the paper scrap on the paper or dust and siphons away.Usually still a little paper scrap and dust can residually be arranged on the paper after removing by air blowing and suction mechanism, this paper scrap and dust at paper with after roller contacts, again easily attached on the roller, so this technology can't be removed paper scrap or the dust that is adsorbed on the roller, therefore still can be subjected to paper scrap or effect of dust.In addition, air-breathing inflatable body and air filter that this Technology Need is bulky, thereby be not suitable in the automatic paper conveying apparatus of miniaturization.
No. 6708009 communique of United States Patent (USP) discloses a kind of printing equipment with dedusting function, and it still utilizes dust-collecting box to collect dust, and strikes off paper scrap and dust on the roller with sponge.Yet, paper scrap and dust only are isolated in outside the paper-feeding channel because of gravity, if the air-flow that will avoid roller to rotate at a high speed being caused blows paper scrap and dust in the feedback paper passage, then the volume potential of dust-collecting box is necessary strengthens, and so still is unfavorable for the development of miniaturization scanning means or printing equipment.
Japan Patent discloses a kind of paper surface deposit removing device for JP10-139225A number, its utilization comprises that the brush of suction mouth cleans paper, but in this device, also exist paper scrap or dust also can be rotated defective in the air-flow rollback paper-feeding channel of generation at a high speed by roller.
Summary of the invention
Therefore, an object of the present invention is to provide a kind of paper conveying apparatus with dedusting function, it utilizes adhesion layer to adsorb paper scrap and dust, reaches dust removing effects in mode cheaply whereby.
For reaching above-mentioned purpose, the invention provides a kind of paper conveying apparatus with dedusting function, it comprises a paper-feeding roller, a dust-collecting box and a bristle pack.Paper-feeding roller is to be used for paper feeding to pass through paper-feeding channel.Dust-collecting box is arranged on a side of paper-feeding roller.Dust-collecting box has one deck adhesion layer, in order to collect and to stick together paper scrap and dust on the paper-feeding roller, to avoid paper scrap and dust by in the rollback paper-feeding channel.Bristle pack contacts with paper-feeding roller, in order to paper scrap on the paper-feeding roller and dust are brushed to dust-collecting box.
Described dust-collecting box can have a recess, in order to additional storage paper scrap and dust, provides bigger control of dust capacity with this.
Description of drawings
Fig. 1 is the paper conveying apparatus with dedusting function according to first embodiment of the invention;
Fig. 2 is the paper conveying apparatus with dedusting function according to second embodiment of the invention.
The specific embodiment
Fig. 1 is the paper conveying apparatus with dedusting function according to first embodiment of the invention.As shown in Figure 1, the paper conveying apparatus with dedusting function 10 of present embodiment comprises two paper-feeding roller 12 and a dust-collecting box 16.Two paper-feeding roller 12 are to be used for paper feeding P to pass through paper-feeding channel 14.Perhaps, can use a paper-feeding roller 12 to cooperate a crawler belt or other member to reach the function that feeds paper.Dust-collecting box 16 is arranged on a side of paper-feeding roller 12, and has one deck adhesion layer 18, in order to collect and to stick together paper scrap and dust on the paper-feeding roller 12.Therefore, can avoid in the air-flow rollback paper-feeding channel 14 that paper scrap and dust produced under high speed rotating by paper-feeding roller 12.This design is for the scanning of high speed or scanning or the printing effect that print speed can provide quite stable day by day.It should be noted that dust-collecting box 16 can be arranged at the below of paper-feeding roller 12, top, left side or right side etc.
In order to remove paper scrap and the dust on the paper-feeding roller 12 fully, can on paper conveying apparatus, set up a bristle pack 20, it is wool felt normally, in order to contact the paper scrap that brushes on the paper-feeding roller 12 and dust with paper-feeding roller 12 to dust-collecting box 16.Adhesion layer 18 is constituted by a two-sided adhesive tape or by glue, provides stickiness to adsorb paper scrap and dust with this.
By above-mentioned design, can increase not significantly under the condition of cost, good dust removing effects is provided.
In another embodiment, dust-collecting box 16 can be a kind of detachable dust-collecting box, allowing the user who belongs to non-maintenance personal can remove dust-collecting box 16 easily and cleaning paper scrap and dust wherein with this, or change two-sided tape and glue, very is to change another new dust-collecting box 16.
Fig. 2 is the paper conveying apparatus with dedusting function according to second embodiment of the invention.As shown in Figure 2, present embodiment is similar to first embodiment, and difference is that dust-collecting box 16 has a recess 19, in order to additional storage paper scrap and dust.Thereby after adhesion layer 18 all had been stained with paper scrap and dust, extra paper scrap and dust can store by landing to recess 19.Usually the Capacity design of dust-collecting box 16 can design the degree of paper scrap and dust spill-over of can not allowing in the service life of scanner or printer, perhaps, dust-collecting box 16 can be designed to the mode that can be changed voluntarily by the user, uses with convenient.
The specific embodiment that is proposed in DETAILED DESCRIPTION OF THE PREFERRED all is to be used for convenient explanation technology contents of the present invention, and be not with narrow sense of the present invention be limited to the foregoing description, under the situation that does not exceed spirit of the present invention and claim scope, the various changes of being made all belong to scope of the present invention.
