Description
Technical field
The utility model relates to thermal printer, especially relates to a kind of core device for thermal printer.
Background technology
In existing core device, need to arrange printhead fixed head specially, printhead fixed head is for controlling the stroke of print head assembly swing.Printhead fixed head needs to be paid by screw lock to be connected on pedestal; Gear cap for covering gear drive group also needs to be paid by screw lock to be connected to pedestal; Such structure is more complicated, and securing member used is more, and manufacture assembling inconvenience, cost is higher; Adopt shell fragment to the force of print head assembly in addition, shell fragment is not all even stable to print head assembly applied pressure, can affect printing effect.
Summary of the invention
The purpose of this utility model be to provide structure simple, manufacture easy to assembly, reduce costs, and all even stable to print head assembly applied pressure, make printing effect better a kind of core device for thermal printer.
The utility model adopts following technical scheme:
For a core device for thermal printer, comprise pedestal and be arranged on motor, driving gear pair, gear cap, print head assembly, rubber-covered roll gear and the rubber roll component on pedestal; Driving gear pair is located at pedestal side, and gear cap covers driving gear pair, and driving gear pair connects with rubber-covered roll gear, and rubber-covered roll gear is located at rubber roll component one end, and gear cap is connected with pedestal one side;
Described core device also comprises printhead stage clip, and described pedestal is integral type plastic cement pedestal, and described motor is installed and to be positioned in draw-in groove set by pedestal and fastening by securing member, and described print head assembly to be located in pedestal draw-in groove and to be compressed location by printhead stage clip; Described gear cap is provided with snap fit, and the snap fit of gear cap embeds in draw-in groove set by pedestal, and snap fit elasticity blocks gear cap.
Described securing member is preferably screw.
Described printhead stage clip is preferably pagoda type stage clip.
The quantity of described snap fit is preferably 4.
Compared with the prior art, the utility model tool has the following advantages:
Pedestal is made as integral structure, without the need to arranging print head assembly fixed head, the function controlling print head assembly stroke is directly realized by pedestal, structure is obviously succinct, manufactures assembling convenient, saves time, save fixed head trip bolt 2, gear cap paid by screw lock and be improved to snap fit buckle-type, save again 2 locks and pay screw, cost obviously reduces.To change stage clip into print head assembly force-applying piece, stage clip is more all even more stable to print head assembly applied pressure than shell fragment, the better effects if of printing.
