Rail fixing device for label printer

Abstract

The invention relates to a rail fixing device for a label printer. The rail fixing device comprises a base seat and a left guide rail and a right guide rail which are arranged on the base seat and further comprises a moving baffle, a fixed baffle, a fixed plate, a gear, a first toothed bar and a second toothed bar, wherein the fixed baffle is fixed on the right guide rail, the moving baffle is connected with the left guide rail through a locking mechanism, the first toothed bar is fixedly connected with the left guide rail, the second toothed bar is fixedly connected with the right guide rail,the first toothed bar and the second toothed bar are parallelly and oppositely arranged on the two sides of the gear and are engaged with the gear, the gear, the first toothed bar and the second toothed bar are installed on the fixed plate, and the fixed plate is fixed on the base seat. According to the rail fixing device for the label printer, the left rail and the right rail realize equidistance synchronous movement through gear and toothed bar transmission, therefore, the fact that the position of a label is maintained at the centered position all the time can be realized, a guide rail locking function can be realized through simple folding actions of the moving baffle, and operations are convenient.

Description

technical field [0001] The invention relates to the field of signage printers, more specifically, to a rail fixing device for a signage printer. Background technique [0002] At present, the print head of the signage printer is generally placed in the center relative to the signage conveying track, so the signage must also be placed in the center on the track during the conveying process to avoid printing skew. The centering of the signboard in the prior art is realized through two rails, and the rail fixing method is to install a screw in one of the rails, and put a baffle at the bottom of the screw. When moving the track to the desired position, use the thumb screw to raise the position of the stopper to the point where the track and the transport plane can be clamped to fix the track. The problem with this structure is that usually when the screw is screwed, the baffle will rotate synchronously with the screw, and the track cannot be locked. At the same time, the locking...

AI Technical Summary

Problems solved by technology

The problem with this structure is that usually when screwing the screw, the baffle will rotate synchronously with the screw, and the track cannot be locked. At the same time, the locking screw needs to be turned multiple times to be tightened, and the whole operation is not very convenient.
