Abstract
The utility model discloses a locating structure of the heating part of a thermosensitive printer core, comprising a thermosensitive head fixed axle, a thermosensitive head central locating support and a radiating fin, wherein the thermosensitive head fixed axle passes through the thermosensitive head central locating support; both ends of the central locating support are provided with thermosensitive head locating blocks used to fix the thermosensitive head fixed axle; moreover, the fixed thermosensitive head fixed axle is embedded on the radiating fin; the central locating support has the effect of locating; moreover, the locating blocks arranged at both sides have elliptic holes which bring a certain degree of freedom to the radiating fin to correct the error generated during assembly, thereby ensuring even pressure between the heating part and a rubber roll. The utility model which has a simple structure and convenient manufacture can be used in various printers. Moreover, a printer adopting the utility model can greatly improve print quality.
Description
Technical field
The utility model relates to a kind of location structure, specially refers to a kind of location structure of temperature-sensitive printer core heating part.
Background technology
Printer is an important peripheral equipment of computer, and people can be printed the content on the computer by printer.The kind of printer is a lot, classifies from printing type: the miniature printer of pin type, the miniature printer of temperature-sensitive, the miniature printer of hot transfer printing etc.To be print needle bump colour band be imprinted on the printing ink of colour band on the printing paper the little printing type of playing employing of pin type, the mode of temperature-sensitive is to make the thermal media variable color that is coated on the printing paper with the mode that heats, and hot transfer printing is that the mode of the carbon dust on the carbon ribbon by heating is imprinted on carbon dust on the printing paper.The temperature-sensitive printer is a kind of printer that comparatively generally uses.As shown in Figure 1, the heating part of traditional temperature-sensitive printer core is directly to be through on the hole slot of fin 102 by a circular shaft 101, and then fixedly on the printer support 103.Such structure causes heating part to influence the quality of printing with the left and right sides discontinuity that cooperates of rubber roll easily.
The utility model content
In order to overcome the shortcoming and defect of existing temperature-sensitive printer core heating part location structure, the utility model provides a kind of location structure of temperature-sensitive printer core heating part, and it can revise the error that assembling causes, has guaranteed that the pressure of heating part and rubber roll is even.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of location structure of temperature-sensitive printer core heating part, comprise thermal head fixed axis, thermal head centralized positioning support and fin, it is characterized in that, described thermal head fixed axis passes thermal head centralized positioning support and at its two ends the thermal head locating piece that is used for fixing the thermal head fixed axis is set, and the thermal head fixed axis that fixes is embedded on the fin.
Thermal head fixed axis described in the utility model is a cylindrical shaft.
Thermal head locating piece described in the utility model is provided with the elliptical aperture that is used for fixing the thermal head fixed axis.
Fin described in the utility model is provided with the hole slot that is used for embedding the thermal head fixed axis.
The beneficial effects of the utility model are, the location structure of a kind of temperature-sensitive printer core heating part of the present utility model, be the thermal head locating piece that is used for fixing the thermal head fixed axis that the thermal head fixed axis is passed thermal head centralized positioning support and be provided with slotted eye at its two ends, and then peace embed on the groove of fin.The centralized positioning support plays the effect of location, and the locating piece on both sides has guaranteed that the pressure of heating part and rubber roll is even owing to there is elliptical aperture to revise the error that assembling causes for the fin level of freedom.The utility model is simple in structure, and is easily manufactured, can be used for various printers.Adopt printer print quality of the present utility model to obtain very big improvement.

The specific embodiment
Describe and other technology contents, characteristics and effect about the utility model, in the detailed description of a first-selected embodiment in following cooperation with reference to the accompanying drawings, can clearly present.
Consult Fig. 1, be the overall structure schematic diagram of traditional temperature-sensitive printer.The heating part of traditional temperature-sensitive printer core is directly to be through on the hole slot of fin 102 by a circular shaft 101, and then fixedly on the printer support 103.Such structure causes heating part to influence the quality of printing with the left and right sides discontinuity that cooperates of rubber roll easily.
Consult Fig. 2, be the overall structure schematic diagram of temperature-sensitive printer of the present utility model, comprise thermal head 16, major axis rubber roll 3, printer stand 6, gear-box.Thermal head 16 comprises thermal head fixed axis 1, thermal head centralized positioning support 2 and fin, and thermal head fixed axis 1 passes thermal head centralized positioning support 2 and at its two ends the thermal head locating piece 18 that is used for fixing thermal head fixed axis 1 is set, and the thermal head fixed axis 1 that fixes is embedded on the fin.Thermal head locating piece 18 is provided with the elliptical aperture that is used for fixing thermal head fixed axis 1.
Like this thermal head fixed axis 1 is passed thermal head centralized positioning support 2 and be provided with the thermal head locating piece 16 that is used for fixing the thermal head fixed axis of slotted eye at its two ends, and then peace embeds on the groove of fin.Thermal head centralized positioning support 2 plays the effect of location, and the thermal head locating piece 16 on both sides has guaranteed that the pressure of heating part and rubber roll is even owing to there is elliptical aperture to revise the error that assembling causes for the fin level of freedom.
Major axis rubber roll 3, gear-box are arranged on the printer stand 6.Also be provided with on the printer stand 6 and grow paper paper blocking piece 4 and short paper delivery paper blocking piece 5.
Gear-box is provided with axle sleeve 7, gear 9 and 11, gear-box catch 19, motor gear 12, gear catch 13.Gear-box catch 19 is used for sealing gear-box, and motor gear 12 is used for driven gear 9 and 11.Gear catch 13 is used for fixing gear.
The temperature-sensitive printer also is provided with detecting winding displacement 14, turning wheel 15 and feed roller 16 and helps print.
The utility model is simple in structure, and is easily manufactured, can be used for various printers.Adopt printer print quality of the present utility model to obtain very big improvement.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
