Abstract
The utility model relates to a printer gear set and especially relates to a broad-breadth heat-transfer label-printer gear set. The printer gear set is characterized in that the printer gear set comprises a driving wheel set, a rubber-roll driving gear, a rubber roll, a colored tape driving gear, an colored-tape tensioning roller, an adhesive-tape driving gear, an adhesive tape roller, a damping gear and a one-way clutch. The printer gear set provided by the utility model has the advantages of reasonable structure design, simple product structure, practicability and significantly low cost. A stepping motor is used and the gear set is artfully matched and mounted, so that three rotary shafts can be driven, and a certain fitting relation can be satisfied.
Description
Technical field
The utility model relates to a kind of printer gear group, particularly a kind of wide cut heat transfer label printer gear group.
Background technology
Heat transfer printer needs colour band and two kinds of consumptive materials of adhesive tape when printing, these two kinds of consumptive materials all are to twist on a kind of cylinder, during ready-to-print, colour band and adhesive tape to be pressed between printhead and the rubber roll, during printing along with the rotation of rubber roll, colour band and adhesive tape also can be under the drive of rubber roll advanced in unison, the content of label just is printed on the adhesive tape.And for colour band two cylinders are arranged, and during printing, a cylinder is put colour band, and a cylinder is received colour band, only has a cylinder for adhesive tape, and during printing, cylinder rotates with the traction of adhesive tape, and when refunding adhesive tape, the tape roller backward rotation is regained adhesive tape.
It more than is heat transfer printer driving process to adhesive tape and colour band when printing.For realizing above-mentioned functions, some heat transfer printers can be realized above-mentioned functions with two sleeve gear groups, and the set of gears group is used for driving tape roller and rubber roll; Another set of gear is used for driving two cylinders of colour band, and motor also can use two.For realizing rewinding and the matching relationship that some are complicated, can use some special accessories such as miniature electric clutch etc. simultaneously, conventional tooth wheels complex structure, manufacturing cost is high.
The utility model content
The purpose of this utility model is to overcome existing the problems referred to above in the prior art, and a kind of reasonable in design, the printer gear group that simple, precision is high, stable, cost is low are provided.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this printer gear group, it is characterized in that, comprise drive gear set, the rubber roll driven wheel, rubber roll, the colour band driven wheel, the colour band take-up roll, the adhesive tape driven wheel, tape roller, damping gear and one-way clutch, described drive gear set is connected by meshing transmission by damping gear and adhesive tape driven wheel, drive gear set and rubber roll driven wheel are connected by meshing transmission, described rubber roll driven wheel and colour band driven wheel are connected by meshing transmission by damping gear, described tape roller is in transmission connection by one-way clutch and adhesive tape driven wheel, described colour band take-up roll is in transmission connection by one-way clutch and colour band driven wheel, and described rubber roll is fixed on the rubber roll driven wheel.Whole gear train only needs a driven wheel to drive, and is simple in structure, low cost of manufacture.
As preferably, described tape roller is identical with the diameter of colour band take-up roll, and the diameter of tape roller and colour band take-up roll is greater than the diameter of rubber roll.
As preferably, also include stepping motor gear, stepping motor gear is meshed with drive gear set.Control the driving direction of driven wheel by stepping motor gear.
The beneficial effects of the utility model are: this product structure is simple, and practicality has significantly reduced cost, uses a stepper motor, is equipped with by gear train cleverly, has realized the driving of three turning cylinders, and has satisfied certain matching relationship.
Description of drawings
Fig. 1 is structural representation of the present utility model.

Fig. 3 is the cutaway view of B-B among Fig. 1.
Fig. 4 is the cutaway view of C-C among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: referring to Fig. 1-4, the utility model embodiment comprises drive gear set 1, rubber roll driven wheel 2, rubber roll 3, colour band driven wheel 4, colour band take-up roll 5, adhesive tape driven wheel 6, tape roller 7, damping gear 8, one-way clutch 9 and stepping motor gear 10.
The direction that arrow represents among the figure as shown in Figure 1 is the rotation direction of each parts when normally printing, and think that the rotation direction of each parts is forward this moment.
When adhesive tape driven wheel 6 forward, one-way clutch 9 is inoperative in the present embodiment, and 6 pairs of tape rollers 7 of adhesive tape driven wheel do not have driving force; When 6 counter-rotating of adhesive tape driven wheel, one-way clutch 9 works, and adhesive tape driven wheel 6 will drive tape roller 7 backward rotation.When colour band driven wheel 4 forward, one-way clutch 9 works, and colour band driven wheel 4 drives 5 rotations of colour band take-up roll and carries out take-up; When 4 counter-rotating of colour band driven wheel, one-way clutch 9 is inoperative, and 4 pairs of colour band take-up roll 5 of colour band driven wheel do not have driving force.
Stepping motor gear 10 drives drive gear set 1 in the course of work, then drive gear set 1 drives damping gear 8 by rubber roll driven wheel 2 engaged transmission again, when damping gear 8 drives colour band driven wheel 4 forward, colour band take-up roll 5 is forward together also, when colour band take-up roll 5 is rotated owing to the pulling force prevention of colour band, this pulling force has surpassed the driving force that damping gear 8 can provide, damping gear 8 will produce sliding friction, colour band take-up roll 5 can stop operating, but the sliding friction of damping gear 8 still can continue to transmit certain driving force to colour band take-up roll 5.
During normal the printing, when adhesive tape and colour band are pressed on the rubber roll 3, final speed is determined by rubber roll 3, but colour band take-up roll 5 relative rubber rolls 3 have the trend of a speed difference, colour band between colour band take-up roll 5 and the rubber roll 3 will be tightened up like this, because the existence of damping gear 8, colour band take-up roll 5 finally can be identical with the speed of rubber roll 3, but can apply a tractive force to colour band, this tractive force is the frictional resistance that comes from damping gear 8, and actual effect is, because the existence of speed difference, colour band take-up roll 5 can be tightened up colour band all the time with certain power, be unlikely to loose, just as magnetic tape station.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
