The following specific embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
The specific embodiment
See also Fig. 1, in a preferred embodiments of the present invention, a printer comprises an adjusting device.Said adjusting device is in order to adjust the distance between a paper 100 to the one ink-jets combination 200, comprises a bearing 10, a power transmission shaft 20, two paper feed idle pulleys 30, a paper-feed 50, an and transmission combination 60.
The one side extension of said bearing 10 is provided with two fixed parts 11 and a location division 13.Said location division 13 and forms a resettlement section 15 in order to accommodate said paper feed idle pulley 30 between the fixed part 11 adjacent with each between said two fixed parts 11.Each fixed part 11 comprises a roof 111, a diapire 112, a first side wall 113 and second sidewall 114.Said roof 111, diapire 112, the first side wall 113 and second sidewall 114 connect said bearing 10, and surround and form a receiving space 116.Said diapire 112 is offered a groove (figure does not show), in order to an elastic component 70 to be installed.Said second sidewall 114 is offered a breach 1141 and a chute 1143 that is communicated with said receiving space 116.Said breach 1141 is communicated with said chute 1143.Said location division 13 comprises a link 131 and a positive stop end 133.Said link 131 connects said bearing 10, and said positive stop end 133 bends extension downwards from the top of said link 131, and and said link 131 between form a stopper slot 135.
Be fixed with said two paper feed idle pulleys 30 on the said power transmission shaft 20.In one embodiment, the cross section of said power transmission shaft 20 and two paper feed idle pulleys 30 is circular.The diameter of said paper feed idle pulley 30 is greater than the diameter of said power transmission shaft 20.
Said paper-feed 50 is in order to cooperate with said paper feed idle pulley 30, to transmit paper 100.In one embodiment, the cross section of said paper-feed 50 is circular.
Said transmission combination 60 is in order to accepting the paper 100 from said paper feed idle pulley 30 and paper-feed 50 transmissions, and comprises one first roller 61 and second roller 63.In one embodiment, the cross section of said first roller 61 and second roller 63 is circular.The diameter of said second roller 63 is greater than the diameter of said first roller 61.
Said ink-jet combination 200 comprises a print cartridge 201, an and nozzle 202 in order to ink-jet.
Please consult Fig. 2-4 simultaneously, during assembling, said elastic component 70 is fixed in the groove of said diapire 112.Said two paper feed idle pulleys 30 respectively near said resettlement section 15, are stretched into said power transmission shaft 20 in the stopper slot 135 of said location division 13, and be housed in the said chute 1143 along said breach 1141.The two ends of said power transmission shaft 20 are shelved on respectively on the said elastic component 70.Said paper-feed 50 is fixed on the top of said two paper feed idle pulleys 30, and with said paper feed idle pulley 30 near or and said paper feed idle pulley 30 between leave the slit.Said transmission combination 60 is fixed on a side of said bearing 10, said first roller 61 near said second roller 63 or and second roller 63 between leave the slit that lets said paper 100 pass.Said ink-jet combination 200 is fixed between said paper-feed 50 and the said transmission combination 60.
During work, said paper 100 skids off between said two paper feed idle pulleys 30 and said paper-feed 50.See also Fig. 2, when said paper 100 was thin, said paper 100 compressed said two paper feed idle pulleys 30, and the upper surface of said paper 100 and said paper-feed 50 are tangent.At this moment, said elastic component 70 has a less deformation quantity.See also Fig. 3, when said paper 100 was thicker, said paper 100 compressed said two paper feed idle pulleys 30, and ordered about said power transmission shaft 20 and move down along said chute 1143.What said elastic component 70 received said power transmission shaft 20 compresses generation compression, and at this moment, said elastic component 70 has bigger deformation quantity, and the upper surface of said paper 100 and said paper-feed 50 are tangent.Because the invariant position of said nozzle 202 and said paper-feed 50, so said paper 100 is constant to the distance between the said nozzle 202.The paper 100 that between said two paper feed idle pulleys 30 and said paper-feed 50, slides makes up 200 belows from said ink-jet and slips over, and skids off along between the said transmission combination 60.When said paper 100 was in said nozzle 202 belows, said nozzle 202 was sprayed onto the upper surface of said paper 100 with ink, and said paper 100 is printed.
