Description
Technical field
The utility model relates to a kind of ribbon cartridge, and is especially a kind of to the improved ribbon cartridge of transport sector.
Background technology
Most ribbon cartridge is generally by colour band, moulding and some spare and accessory parts such as iron plate, and compositions such as spring can be divided into body, lid, colour band and colour band transport sector according to function.During printing, by the colour band transport sector colour band is sent in cycles, printer clocklike goes out pin by printhead and constantly impacts the colour band tape base, the printing ink on the colour band is transferred to realized print procedure on the print media.Colour band transport sector early generally has two kinds of structures: gear transmission structure or wind rumble transmission structure, constantly colour band is sent to the other end of ribbon cartridge from an end of ribbon cartridge by transport sector, and realize colour band cyclic transfer.
The ribbon cartridge of employing gear transmission structure generally reaches the driven gear 4 that is meshed with it by body 1, lid 2, driving gear 3 and forms as shown in Figure 1.Engaged transmission by driving gear and driven gear in print procedure is transmitted colour band.Colour band constantly is deposited in the band edge of going into of ribbon cartridge, by the thrust of nylon tape, nylon tape is pushed to the other end of ribbon cartridge by an end of ribbon cartridge.
But also there is shortcoming in this colour band transmission structure device: at first, colour band can't well be unfolded in limited ribbon cartridge space, and the colour band folding length diminishes, and influences print life and product quality; Secondly, colour band directly transmits by the engagement between gear, and colour band is deposited in easily into band edge like this, and it is too crowded to go into band edge, and colour band wraps in easily on the travelling gear and can't rotate in the time of seriously, the band phenomenon occurs.
For overcoming the above problems, also coloured tape drum improves above transmission structure now, as shown in Figure 1, has promptly increased conduction band frame 5,6.Conduction band frame 5 have with driving gear 3 cog 32 and lower gear 33 between the face 51 that cooperates of optical axis 34, in the use, driving gear 3 covers on 2 by axle 31 rotating being fixed on, conduction band frame 5 by face 51 and driving gear 3 cog 32 and lower gear 33 between optical axis 34 cooperate; Conduction band frame 6 cooperates with driven gear 4 by similar method.When driving gear and driven gear rotation drive colour band, colour band enters into band edge by conduction band frame 5,6, has more effectively avoided colour band to wrap in easily and has caused gear can't rotate the band phenomenon of generation on the travelling gear.
But therefore above improvement can not avoid the band phenomenon fully because the conduction band frame can not avoid too crowded into the band edge colour band.
Summary of the invention
The purpose of this utility model is to provide a kind of improved ribbon cartridge, solves colour band and is deposited in easily into band edge, goes into the too crowded band problem that is produced of band edge.
For this reason, the technical solution of the utility model is: adopt a driving gear, be rotatably supported between body and the lid, the driving gear middle part has one section optical axis 310 that is provided with drive division 320; Also have one with the driven gear of driving gear engagement, be rotatably supported between body and the lid, have one section optical axis 410 that is provided with drive division 420 in the middle part of the driven gear; One conduction band frame 500, it can be installed on the body movably along described driving gear and driven gear meshing point tangential direction, and conduction band frame 500 and described optical axis 310 relative faces 530 are provided with a pair of driving gear 510,520 that can cooperate with described drive division 320; One conduction band frame 600, it can be installed on the body movably along described driving gear and driven gear meshing point tangential direction, and conduction band frame 600 and described optical axis 410 relative faces 630 are provided with a pair of driving gear 610,620 that can cooperate with described drive division 420.
In transmission ribbon motion process, when driving gear and driven gear drive division turn to the driving gear 520 of conduction band frame 500 and 600 and 620 positions, driving gear and driven gear drive division begin to promote conduction band frame 500 and 600 to left movement, and conduction band frame 500 and 600 promotes colour band again to left movement; When driving gear and driven gear drive division turn to the driving gear 510 of conduction band frame 500 and 600 and 610 positions, driving gear and driven gear drive division begin to promote conduction band frame 500 and 600 and move right, conduction band frame 500 and 600 retreats to the right initial position, realized colour band is promoted once to the left side by the right, circulation for the first time finishes; When driving gear and driven gear drive division turn to the driving gear 520 of conduction band frame 500 and 600 and 620 positions, circulation beginning for the second time, equally colour band is promoted to the left side by the right, like this, driving gear and driven gear constantly rotate and drive conduction band frame 500 and 600 continuous iterative motions, constantly colour band are promoted to the left side by the right.
New construction has utilized the rack-and-pinion transmission principle, with rotatablely moving of driving gear and driven gear, is converted into conduction band frame 500 and 600 rectilinear motion that moves in circles and promotes colour band and constantly travel forward.
This improved ribbon cartridge has following advantage:
Colour band is transmitted by the engagement between gear, constantly pushes out colour band to band edge by going into band edge by the iterative motion of conduction band frame again, like this, goes into band edge and is not easy to pile up colour band, and gear rotates smooth and easy, has avoided occurring the band phenomenon.
Colour band becomes big in the space of going into band edge, and it is big that the colour band folding length becomes, and improved print life and product quality.
