Abstract
The utility model relates to a ribbon cartridge of a stylus printer of a ribbon transmission, applying the ribbon transmission. The ribbon transmission comprises a cylindrical gearwheel and a cylindrical shaft sleeve. The cylindrical shaft sleeve is inserted into the intra-cavity of the cylindrical gearwheel. The power transmission between the cylindrical shaft sleeve and the cylindrical gearwheel can be realized by the matching of a rib on the surface of an outer cylinder of the cylindrical shaft sleeve that convexly stretches out and can be elastically telescopic along the radial direction of the cylindrical shaft sleeve, and a groove arranged inside the intra-cavity of the cylindrical gearwheel. With the ribbon cartridge of the stylus printer of the ribbon transmission applied, the negative effects produced by a ribbon transmission shaft due to the augmentation of a girth gear or a rotary torsional moment can be effectively avoided.
Description
Technical field
The utility model relates to Stylus printer ribbon cartridges and gear, particularly by for example external motor-driven Stylus printer ribbon cartridges and gear of outside rotating power source.
Background technology
Impact printer is a modern handle official bussiness PRN device commonly used.Though use the laser printer of the based colorant of carbon dust to obtain to use comparatively widely, yet impact printer still has wide application, for example taxi meter, shop valuation document, office document printing etc.Also just bearing the mission that colouring agent is provided to recording medium accordingly with the matching used ribbon cartridge of impact printer.Common impact printer ribbon cartridge, its structure comprise colour band box body, travelling gear, colour band stage clip etc.In working order down, clocklike go out pin and constantly impact the nylon tape base, the printing ink on the nylon tape is transferred on the recording medium such as paper, realize the character print procedure by printing syringe needle.
In the character print procedure, the transmission of colour band depends on the frictional drive of the transmission mechanism that is provided with in rotary driving force that external drive motors provides and the ribbon cartridge.Transmission mechanism is passed to the rotary power of external drive motors on the colour band by the output shaft engagement of power transmission shaft and external drive motors, orders about colour band and constantly does annular movement.Colour band is after operation after a while, printing ink on its tape base is approach exhaustion gradually, tape base also can be subjected to impact wear, perhaps produce disturbance in the colour band operation, cause under fuzzy, the messy situation of printing writing, usually the user can take colour band that more renews or the installment state of adjusting colour band, to eliminate these problems.On the other hand, because ribbon cartridge has the characteristics of automatic operation, when above-mentioned phenomenon occurring, for example the tape base volume is lived gear, the colour band required driving torque will increase gradually, print needle occurs when perhaps changing ribbon cartridge or printhead and tangle colour band, cause the colour band travelling gear to skid, the driving torque increases, the driving moment that increases or drive torque and will directly put on active force on the output shaft of the power transmission shaft of ribbon cartridge transmission mechanism and external drive motors, cause the output shaft of the power transmission shaft of ribbon cartridge transmission mechanism or external drive motors impaired, form the permanent breaking-up that is difficult to repair.
In the face of this technological deficiency, the part printer of nearest exploitation just attaches color band driving shaft protective device, and the elasticity connecting axle of combination or separation force is provided by spring as design on the printer driver axle.When the moment of torsion that transmits when colour band is big; this elasticity connecting axle is brought into play the centrifugation of its arrangement of clutch; the power transmission shaft of ribbon cartridge transmission mechanism or the driving shaft of external drive motors are skidded; thereby avoid twisting off ribbon cartridge transmission mechanism power transmission shaft or external drive motors driving shaft; or break the colour band tape base, in order to protection colour band or corresponding power transmission shaft.Yet after long-term the use, spring is aging, and elastic force descends, and when the reverse moment of torsion that produces at colour band is big slightly, the protection action that power transmission shaft skids will occur, and causes the colour band cisco unity malfunction.
For example, CN00132550.7 number domestic patent of invention specification discloses a kind of drive axle of colour ribbon.Be provided with arrangement of clutch between driving shaft and the driving cog wheel disc.Arrangement of clutch is made of the driving gear cover on top and the clutch bulge loop of bottom.Driving gear cover socket bulge loop, bulge loop places on the driving cog wheel disc.Driving cog wheel disc upper surface is provided with jut.Corresponding jut overlaps should jut is provided with recess in the bulge loop bottom surface.The driving gear cover is hollow form, and driving shaft is inserted in the driving gear cover, fixes as one by pin.Be inserted in the colour band frame location notch hole driving gear cover end.This invention can prevent effectively that the driving shaft that causes because of cassette tape from being twisted off, and can send the mechanical impact warning in time, reminds the user to shut down immediately, removes fault.Yet on the other hand, as described above, protection action mistaken ideas not only may appear in this technical scheme influences print progress, and its structure is comparatively complicated, and its maintenance cost is higher.
