Description

Guide rod sliding block module for printer Technical Field The utility model relates to the technical field of printers, in particular to a guide rod sliding block module for a printer. Background In a print head moving mechanism of a printer, a guide rod and slide block module is a key component for realizing linear precise transmission. However, the slider and the guide rod in the existing printer guide rod slider module are of an integrated or complex connection structure, when the slider or the guide rail needs to be maintained and replaced, the slider or the guide rail is difficult to separate and detach, time and labor are consumed, maintenance cost and downtime are increased, on the other hand, wiring inside the printer is complex, wiring harnesses such as winding and interference with the moving slider can influence normal operation of the slider, even the wiring harnesses and the slider structure are damaged, and stability and service life of the printer are reduced. Therefore, in order to further meet the use requirements of the printer for high efficiency, stability and easy maintenance, it is necessary to provide a novel modularized technical scheme. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide a novel guide rod sliding block module for a printer, wherein the guide rod sliding block is convenient to separate and maintain and replace, and is provided with an isolation mechanism. In order to solve the technical problems, the utility model adopts the following technical scheme: The guide rod sliding block module for the printer comprises an inner mounting plate, wherein two rows of parallel opposite V-shaped guide rods are rotatably arranged on the inner mounting plate, the groove surfaces of the upper and lower rows of opposite V-shaped guide rods are opposite, a detachable sliding block is clamped between the upper and lower rows of opposite V-shaped guide rods, the front part of the sliding block is used for mounting a printing head, the rear part of the sliding block is connected with a synchronous belt, the left and right ends of the synchronous belt are respectively connected with a synchronous wheel in a winding manner, and one of the two synchronous wheels is connected with a driving rotating shaft of a stepping motor; The two rows of the oppositely-installed V-shaped guide rods are synchronously fixed or rotated.
