Abstract
The utility model discloses a structure used for thermal printing head temperature control. The structure comprises a thermal printing head, an aluminium-based heat sink, an airflow pipe, and a temperature adjustable fan. The structure is characterized in that the single or the plurality of thermal printing heads are arranged and installed on the aluminium-based heat sink in sequence, and the aluminium-based heat sink is provided with a pipe through which airflow flows uniformly. The temperature adjustable fan transports airflow through the airflow pipe to cool down or heat up the thermal printing head. Airflow enters one end of the pipe of the aluminium-based heat sink, and flows to the temperature adjustable fan from the other end of the pipe, so as to accurately control air current circulation and airflow temperature. The structure can ensure heat of the thermal printing head is radiated in time, and the structure controls temperature of the thermal printing head more accurately, thereby greatly improving stability and working efficiency of a device, and reducing loss and waste of processing.
Description
Technical field
The utility model relates to a kind of for the temperature controlled structure of thermal printing head, relates in particular to a kind of structure of controlling thermal head temperature with air-flow.
Background technology
Thermal printing head, is mainly comprised of ceramic substrate, heat sink, PCB tri-parts.Existing thermal printing head, in the less situation of the density of print What, generally adopts heat sink natural heat dissipation or controls by natural temperature.But when in large density printing or flying print, the heat producing due to thermal head increases considerably, and heat above thermal printing head can not distribute in time, iff the function of using thermal printing head natural heat dissipation, result can have a strong impact on the operating efficiency of printer and be printed as power.Meanwhile, using natural temperature heat radiation, can be because cannot control accurately water temperature, cause temperature controlled inaccurate to thermal head, also can have influence on printing effect, even cause and print unsuccessfully.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of for the temperature controlled structure of thermal printing head, can guarantee leaving in time of thermal printing head temperature, more accurately thermal printing head temperature is controlled simultaneously, stability, the operating efficiency of the equipment greatly improving, reduced loss and the waste of processing.
Described in the utility model a kind of for the temperature controlled structure of thermal printing head, comprise: thermal printing head, aluminium base heat sink, airflow line, adjustable temperature blower fan, it is characterized in that: single or a plurality of thermal printing heads are arranged in order and are arranged on aluminium base heat sink, be provided with and be convenient to the pipeline that air-flow evenly passes through in aluminium base heat sink.Adjustable temperature blower fan is by airflow line delivery air for lowering the temperature to thermal printing head or heating up, and air-flow flows into from one end of the pipeline of aluminium base heat sink, from the other end, flows out to adjustable temperature blower fan, with this, reaches the accurate control of airflow circulating and gas flow temperature.
The utility model can guarantee leaving in time of thermal printing head temperature, more accurately thermal printing head temperature is controlled simultaneously, and stability, the operating efficiency of the equipment greatly improving, reduced loss and the waste of processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing explanation, the utility model is further elaborated.
Described in the utility model a kind of for the temperature controlled structure of thermal printing head, comprise: thermal printing head 1, aluminium base heat sink 2, airflow line 3, adjustable temperature blower fan 4, it is characterized in that: single or a plurality of thermal printing heads 1 are arranged in order and are arranged on aluminium base heat sink 2, in aluminium base heat sink 2, are provided with and are convenient to the pipeline that air-flow evenly passes through.Adjustable temperature blower fan 4 is the pipeline one end to aluminium base heat sink 2 by airflow line 3 delivery airs, for lowering the temperature to thermal printing head or heating up, air-flow flows into from one end of the pipeline of aluminium base heat sink 2, from the other end, flow out to adjustable temperature blower fan 4, with this, reach the accurate control of airflow circulating and gas flow temperature.The gas flow temperature that can flow in aluminium base heat sink 2 by 4 pairs of adjustable temperature blower fans is controlled accurately, meets the needed condition of printing.Simultaneously because the air-flow in pipeline belongs to closed state, the control to temperature is more accurate.Air-flow is when being provided with the aluminium base heat sink 2 of thermal printing head 1, by the heat of taking away thermal printing head 1 and producing, thereby is reached for the effect of thermal printing head 1 cooling.When air-flow flow into adjustable temperature blower fan 4 again from the pipeline other end of aluminium base heat sink 2, by the air-flow of 4 pairs of inflows of adjustable temperature blower fan, lower the temperature again, to reach the consistent of gas flow temperature in the pipeline that flow into aluminium base heat sink 2.
Meanwhile, consistent with the method for cooling for the method for thermal printhead heats, by 4 pairs of gas flow temperatures of adjustable temperature blower fan, control.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be treated as protection domain of the present utility model.
