Description
Technical field
The present invention relates to a kind of printer carriage, particularly a kind of guiding mechanism of printer carriage transverse shifting.
Background technology
As everyone knows, the impact printer of the overwhelming majority is all to move by word car drive printhead transverse reciprocating on printing paper to print both at home and abroad, when the word car moves as lateral reciprocating displacement along guide rail, easy impact because of vibrations or external force, can not be close to guide rail moves, make the word car jumping phenomena occur, cause printhead prints word or pattern out to depart from the precalculated position, had a strong impact on the printing effect of printer.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of simple in structurely, can prevent that again the guiding mechanism of jumping phenomena from appearring in the word car when transverse shifting.
The present invention for the technical scheme that solves its technical problem and adopt is:
a kind of printer carriage transverse shifting guiding mechanism, comprise the word vehicle frame, the bottom activity of word vehicle frame is coated with the axis of guide, axis of guide top is provided with the guide rail that parallels with it, the top of described word vehicle frame be " U " type and " U " type before, be respectively arranged with front jocket wheel and rear guide wheel on rear jig arm, guide rail is between front jocket wheel and rear guide wheel, front jocket wheel is fixedly mounted on the front jig arm on word vehicle frame top, be installed with rear wheel stand on the rear jig arm on word vehicle frame top, rear guide wheel is movably arranged on rear wheel stand and is provided with for the guide wheel shaft that pushes rear guide wheel on rear wheel stand and makes rear guide wheel press to the elastomeric element of front jocket wheel, the guide wheel shaft of guide wheel after above-mentioned elastomeric element extruding, make rear guide wheel press to front jocket wheel, distance before and after dwindling between guide wheel, thereby the guide rail that will be positioned between the two clamps, make the word car be close to guide rail in the transverse shifting process, prevent that the word car from because of external force or vibration influence, jumping phenomena occuring, guaranteed printing effect.
further, described rear wheel stand middle part is provided with for the movable groove of installing of rear guide wheel, the bottom of groove and opening be front surface and the rear surface of close rear wheel stand respectively, rear guide wheel is movably arranged in groove and elastomeric element pushes the guide wheel shaft of rear guide wheel and makes guide wheel shaft press to the bottom of groove, above-mentioned elastomeric element extruding guide wheel shaft and when making the bottom that it presses to groove, guide wheel shaft can drive rear guide wheel backward the front surface of wheel stand move, make distance between rear guide wheel and front jocket wheel dwindle and clamp be in before, guide rail between rear guide wheel, therefore the word car can be close to guide rail and move as transverse reciprocating.
Further, described elastomeric element is stage clip or shell fragment, and above-mentioned stage clip or shell fragment are convenient to be installed, and helps to reduce labour intensity and reduces production costs.
the invention has the beneficial effects as follows: due to the present invention by " U " shape is arranged to be in word vehicle frame top, and before " U " shape, before front jocket wheel and rear guide wheel being set on rear jig arm and guide rail being placed in, between rear guide wheel, be provided with rear wheel stand on the rear jig arm on word vehicle frame top, rear guide wheel is movably arranged on rear wheel stand and on rear wheel stand and is provided with elastomeric element, push the guide wheel shaft of rear guide wheel and make it press to front jocket wheel by elastomeric element, thereby making front jocket wheel and rear guide wheel clamp causes, assurance word car is close to guide rail, prevent that the word car from occurring beating in the transverse shifting process, guarantee the printing effect of printer, simultaneously, above-mentioned elastomeric element is stage clip or shell fragment, and convenient the installation helps to reduce labour intensity and production cost.
