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 domestic and international overwhelming majority is all drive printhead transverse reciprocating on printing paper to move by word car to print, when word car moves along guide rail as lateral reciprocating displacement, easily because of the impact of vibrations or external force, guide rail can not be close to move, make word car occur jumping phenomena, cause printhead prints word out or pattern to deviate from precalculated position, had a strong impact on the printing effect of printer.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of structure simple, can prevent again word car from occurring the guiding mechanism of jumping phenomena when transverse shifting.
The present invention is the technical scheme that its technical problem of solution adopts:
A kind of printer carriage transverse shifting guiding mechanism, comprise word vehicle frame, the activity of word frame downward is coated with the axis of guide, the guide rail paralleled with it is provided with above the axis of guide, the top of described word vehicle frame is in " U " type and before " U " type, rear jig arm is respectively arranged with front jocket wheel and rear guide wheel, guide rail is between front jocket wheel and rear guide wheel, front jocket wheel is fixedly mounted in the front jig arm on word vehicle frame top, the rear jig arm on word vehicle frame top is installed with rear wheel stand, rear guide wheel to be movably arranged on rear wheel stand and after wheel stand be provided with the guide wheel shaft for extruding rear guide wheel and make 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, rear guide wheel is made to press to front jocket wheel, reduce the distance between the guide wheel of front and back, thus the guide rail clamping that will be positioned between the two, word car is made to be close to guide rail in transverse shifting process, prevent word car from because of external force or vibration influence, jumping phenomena occurring, ensure that printing effect.
Further, the groove installed for rear guide wheel activity is provided with in the middle part of described rear wheel stand, the bottom of groove and opening are respectively near front surface and the rear surface of rear wheel stand, rear guide wheel to be movably arranged in groove and after elastomeric element extruding guide wheel guide wheel shaft and make guide wheel shaft press to the bottom of groove, above-mentioned elastomeric element extruding guide wheel shaft when making it press to the bottom of groove, guide wheel shaft can drive the front surface of rear guide wheel wheel stand backward to move, distance between rear guide wheel and front jocket wheel is reduced and before clamping and being in, guide rail between rear guide wheel, therefore 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 the convenient installation of shell fragment, contribute to reducing labour intensity and reducing production cost.
The invention has the beneficial effects as follows: because the present invention is by being arranged in " U " shape by word vehicle frame top, and before " U " shape, rear jig arm is arranged front jocket wheel and rear guide wheel and before being placed in by guide rail, between rear guide wheel, the rear jig arm on word vehicle frame top is provided with rear wheel stand, rear guide wheel to be movably arranged on rear wheel stand and after wheel stand is provided with elastomeric element, extrude the guide wheel shaft of rear guide wheel by elastomeric element and make it press to front jocket wheel, thus make front jocket wheel and rear guide wheel clamping guide-rail, ensure that guide rail is close to by word car, prevent word car from occurring beating in transverse shifting process, ensure the printing effect of printer, meanwhile, above-mentioned elastomeric element is stage clip or shell fragment, convenient installation, contributes to reducing labour intensity and production cost.
