Description
Technical field
The utility model relates to a kind of printhead, particularly relates to a kind of printhead that is used for miniature bill printer.
Background technology
Along with the fast development of modern retail business, the modernization level of various markets equipment is also maked rapid progress, and wherein miniature bill printer is more and more used.Miniature bill printer general using heat-sensitive paper is as carrier, thereby print literal or figure by the thermal printing head variable color, characteristics such as have that print speed is fast, resolution ratio is high, font clear, long service life attractive in appearance, noise are low, therefore be widely used in hospital, check and verify, lottery ticket printing etc. needs in the industry of a large amount of bill printings.The printhead of the miniature bill printer that occurs on the market takes to adorn easily paper structure (abbreviating easy dress paper structure usually as) mostly at present, the operation principle of this structure generally is earlier air roll and thermal printing sheet to be separated, after putting into thermal printing paper, press air roll last, make thermal printing paper contact, realize printing with the thermal printing sheet.When reality is used, this easy dress paper structure is opened in the process of closing one, gear on the air roll and the travelling gear on the thermal printing head be collision mutually, cause the damaged in collision of gear and thermal printing sheet easily, therefore the printhead of this structure is shorter service life, brings very big loss to the consumer, and foreign matters such as the dust that drops easily on air roll and the thermal printing head, it is no longer flexible to cause gear to rotate, and the thermal printing sheet is no longer sensitive.Also occurred a part on the market and avoided the print head structure that collides and wear and tear by limiting the air roll gear, these print head structures in use, air roll will be pulled open earlier and the thermal printing sheet could be installed thermal printing paper, and internal structure more complicated, cost is higher, is unfavorable for extensive popularization.
The utility model content
The purpose of this utility model provides a kind of printhead that is used for miniature bill printer, can effectively avoid the gouging abrasion of printhead internal gear, can prevent entering of dust foreign matter simultaneously, and service life is longer, and simple in structure, and cost is lower.
For achieving the above object, the technical solution of the utility model is:
A kind of printhead that is used for miniature bill printer, it comprises printhead movement and air roll, described printhead movement comprises the movement gear, described air roll comprises the air roll gear, it is characterized in that: the described printhead that is used for miniature bill printer comprises base plate and the printhead over cap that is arranged on the base plate, described printhead over cap is provided with paper feed port and exit slot, in described printhead movement and the cavity of air roll between printhead over cap and base plate, the printhead movement is fixedlyed connected with base plate, the movement gear is meshed with the air roll gear, and air roll is connected in the printhead movement by movement gear and air roll gear; The described printhead that is used for miniature bill printer also comprises electronic paper feed circuit board and electronic paper feed button, and electronic paper feed button is connected in air roll by electronic paper feed circuit board and controls its paper feed action.
Thermal printing paper enters from paper feed port, press electronic paper feed button, air roll begins to rotate and thermal printing paper is involved in, thermal printing paper passes through from the space between air roll and the printhead movement, finish printing simultaneously, thermal printing paper shifts out from exit slot then, does not need that separately printhead movement and air roll just can be finished paper feed and print procedure.
According to a kind of preferred construction, the manual paper feeding knob is set on air roll, the rotating shaft of manual paper feeding knob is fixedlyed connected with the roll shaft of air roll, carries out the paper feed action thereby the user can rotate air roll by rotation manual paper feeding knob.
As a kind of preferred implementation, the printhead over cap is the plastics printhead over cap that is made of plastics.With plastics is that material can reduce cost.
The utility model also can be done further improvement, and electronic paper feed button and manual paper feeding knob are exposed to outside the printhead over cap.
Therefore compared with prior art, the utility model has following beneficial effect:
(1) air roll and printhead movement all are positioned at the printhead over cap in the utility model, air roll gear and movement gear intermesh, paper feed is printed not to be needed air roll and printhead movement are separated, can effectively avoid the gouging abrasion of printhead internal gear, the printhead over cap can prevent that the dust foreign matter from entering printhead inside in addition, so service life is longer;
(2) electronic paper feed knob in the utility model and electronic paper feed circuit board can be realized electronic paper feed action, operate very easy;
(3) the utility model structure is very simple, and manufacturing cost is lower, promotes easily.
