Abstract
The utility model discloses a kind of Novel ribbon driving mechanism, aim to provide the Novel ribbon driving mechanism that a kind of transmission efficiency is high.It comprises colour band driven wheel, be set in the driving gear on motor output shaft, the travelling gear engaged with driving gear, the duplicate gear that one of them gear engages with travelling gear, two with the wobble gear of another gears meshing of duplicate gear, pivoting friction is arranged at the swing arm on double crosslinking gear shaft, and the transition gear engaged with colour band driven wheel; Described wobble gear is identical with transition gear parameter, and described wobble gear is installed in swing arm, and is that rotating shaft forms swinging structure with double crosslinking gear shaft; When described swing arm swings aside, one of them wobble gear engages with transition gear, and when described swing arm swings to opposite side, another wobble gear engages with colour band driven wheel.The utility model can effectively reduce the volume of transmission mechanism, improves the reliability of transmission efficiency and transmission.
Description
Technical field
The utility model relates to impact printer technical field, especially relates to a kind of Novel ribbon driving mechanism.
Background technology
Colour band driving is the principal organ of impact printer.Impact printer impacts colour band by print needle, impacted by the ink on colour band on the print media of colour band bottom, thus realize the basic function of stylus printer.In order to ensure that, on single page or several pages of media, the ink shades of impact is substantially close, colour band needs to carry out single direction rotation shuttling movement according to certain speed.It is adopt the same motor driving printhead word car horizontal traversal that the colour band of usual impact printer drives.Be so how the horizontal traversal of word car and the one-way movement of colour band by the conversion of motion of motor, different printers has different mechanisms.Usually be all by gear train, power is relayed on the driving mechanism of ribbon cartridge.If the axial direction of the axis direction of motor gear and colour band driven wheel is not in same plane, then in the transmittance process of power, also need to use bevel gear, worms and wormwheels etc. change the gear train in gear direction, these all will reduce the transmission efficiency of gear train, and increase certain resistance.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of structure simple, the Novel ribbon driving mechanism that transmission efficiency is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of Novel ribbon driving mechanism, comprise colour band driven wheel, be set in the driving gear on motor output shaft, the travelling gear engaged with driving gear, the duplicate gear that one of them gear engages with travelling gear, two with the wobble gear of another gears meshing of duplicate gear, pivoting friction is arranged at the swing arm on double crosslinking gear shaft, and the transition gear engaged with colour band driven wheel; Described wobble gear is identical with transition gear parameter, and described wobble gear is installed in swing arm, and is that rotating shaft forms swinging structure with double crosslinking gear shaft; When described swing arm swings aside, one of them wobble gear engages with transition gear, and when described swing arm swings to opposite side, another wobble gear engages with colour band driven wheel.
Compared with prior art, the utility model tool has the following advantages:
The utility model, by arranging the drive disk assembly such as travelling gear, duplicate gear, realizes driving gear and connects with the driving of colour band driven wheel.Ensureing, under the prerequisite that colour band driven wheel rotation direction does not affect by motor steering, drive mechanism to be simplified to greatest extent, effectively reduces the volume of transmission mechanism, improve the reliability of transmission efficiency and transmission.Manufacture originally from complete machine, there is significant economy.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model, wherein for ease of observe, illustrate only the part-structure of duplicate gear, namely duplicate gear and travelling gear meshed gears not completely shown.
Fig. 2 is the structural representation of Fig. 1 motor when rotating backward, and wherein for ease of observing, illustrate only the part-structure of duplicate gear, namely duplicate gear and travelling gear meshed gears not completely shown.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Novel ribbon driving mechanism shown in Fig. 1 and Fig. 2, comprise colour band driven wheel 7, be set in the driving gear 1 on motor output shaft, the travelling gear 2 engaged with driving gear 1, the duplicate gear 3 that one of them gear engages with travelling gear 2, two with the wobble gear 4 of another gears meshing of duplicate gear 3, pivoting friction is arranged at the swing arm 5 on duplicate gear 3 axle, and the transition gear 6 engaged with colour band driven wheel 7; Described wobble gear 4 is identical with transition gear 6 parameter, and described wobble gear 4 is installed in swing arm 5, and is that rotating shaft forms swinging structure with double crosslinking gear shaft; When described swing arm 5 swings aside, one of them wobble gear 4 engages with transition gear 6, and when described swing arm 5 swings to opposite side, another wobble gear 4 engages with colour band driven wheel 7.
The course of work: as shown in Figure 1, when driving gear 1 turns clockwise, travelling gear 2 and duplicate gear 3 matching rotation, duplicate gear 3 drives swing arm 5 to turn clockwise, and allow the wobble gear 4 on right side in swing arm 5 overlap with transition gear 6 to engage, drive colour band driven wheel 7 to be rotated counterclockwise by transition gear 6.
As shown in Figure 2, when driving gear 1 is rotated counterclockwise, travelling gear 2 and duplicate gear 3 matching rotation, duplicate gear 3 drives swing arm 5 to be rotated counterclockwise, and allow the wobble gear 4 of swing arm 5 upper left side overlap with colour band driven wheel 7 to engage, and the last colour band driven wheel 7 that drives is rotated counterclockwise.
To sum up, no matter driving gear 1 clockwise or be rotated counterclockwise, and colour band driven wheel 7 is all that a counterclockwise direction rotates, and reaches colour band and drives unidirectional requirement.
The utility model, by arranging the drive disk assembly such as travelling gear, duplicate gear, realizes driving gear and connects with the driving of colour band driven wheel.Ensureing, under the prerequisite that colour band driven wheel rotation direction does not affect by motor steering, drive mechanism to be simplified to greatest extent, effectively reduces the volume of transmission mechanism, improve the reliability of transmission efficiency and transmission.Manufacture originally from complete machine, there is significant economy.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
