Carriage unit transverse movable guiding mechanism of printer

Abstract

The invention discloses a carriage unit transverse movable guiding mechanism of a printer. The mechanism comprises a carriage unit, wherein a guide shaft is installed on the lower portion of the carriage unit in a movable and penetrating mode, a guide rail which is parallel with the guide shaft is arranged above the guide shaft, the upper portion of the carriage unit is in a U type, a front guide wheel and a rear guide wheel are respectively arranged on a front clamping arm and a rear clamping arm of the U type, the guide rail is located between the front guide wheel and the rear guide wheel, the front guide wheel is fixedly installed on the front clamping arm of the upper portion of the carriage unit, a rear guide wheel seat is fixedly installed on the rear clamping arm of the upper portion of the carriage unit, the rear guide wheel is installed on the rear guide wheel seat in a movable mode, the rear guide wheel seat is provided with an elastic component which is used for extruding a guide wheel shaft of the rear guide wheel and enabling the rear guide wheel to be pressed towards the front guide wheel, the elastic component extrudes the guide wheel shaft of the rear guide wheel to enable the rear guide wheel to be pressed towards the front guide wheel, distance between the front guide wheel and the rear guide wheel is shortened, the guide rail between the front guide wheel and the rear guide wheel is clamped tightly, the carriage unit is enabled to be closely attached to the guide rail in the transverse movable process, the bouncing phenomenon of the carriage unit due to outer force or vibration is prevented, and a printing effect is ensured.

Description

technical field [0001] The invention relates to a printer carriage, in particular to a guide mechanism for the lateral movement of the printer carriage. Background technique [0002] As we all know, most dot matrix printers at home and abroad use the carriage to drive the print head to reciprocate horizontally on the printing paper for printing. When the carriage moves horizontally and reciprocally along the guide rail, it is easy to be affected by vibration or external force. Moving close to the guide rail makes the character carriage jump, causing the characters or patterns printed by the print head to deviate from the predetermined position, which seriously affects the printing effect of the printer. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a guiding mechanism with a simple structure and capable of preventing the character carriage from bouncing when it moves laterally. [0004] The techn...
