Cleaning type Printronix barcode printer achieving automatic replacement of print head

Abstract

The invention relates to a cleaning type Printronix barcode printer achieving automatic replacement of a print head. The cleaning type Printronix barcode printer achieving automatic replacement of theprint head comprises a shell and a color sensor. A rolling shaft, a supporting plate, a main print head, a moving mechanism, a telescopic mechanism, a grabbing mechanism, a washing mechanism, a firstpartition plate, a second partition plate and at least two standby print heads are arranged in the shell. The grabbing mechanism comprises a fixing plate, a first motor, a crank and two grabbing assemblies. A grabbing assembly comprises a drive rod, a driven rod, a supporting rod and a clamping block. The washing mechanism comprises a water spraying assembly and a rotating assembly. According tothe cleaning type Printronix barcode printer achieving automatic replacement of the print head, after the main moving head is moved to the position above a distance sensor on the supporting plate through the moving mechanism and the telescopic mechanism, the main print head is washed through the washing mechanism, residual accumulated thermal transfer ribbons in the main print head are removed, sothat the main print head is kept clean, and therefore the print effect of the Printronix barcode printer is better.

Description

technical field [0001] The invention relates to the field of Printronix barcode printers, in particular to a clean Printronix barcode printer capable of automatically replacing print heads. Background technique [0002] A barcode printer is a dedicated printer. The biggest difference between barcode printers and ordinary printers is that the printing of barcode printers is based on heat, and the printing is completed with carbon ribbon as the printing medium. The biggest advantage of this printing method compared with ordinary printing methods is that it can be used in unattended Realize continuous high-speed printing under the condition of. [0003] During the printing process of the existing barcode printers, the print head is prone to the accumulation of carbon ribbons, resulting in inconsistent printing depths, which greatly reduces the printing effect and reduces the printing effect of the existing barcode printers. Not only that, in After a long time of use, the prin...

Problems solved by technology

[0003] During the printing process of the existing barcode printers, the print head is prone to the accumulation of carbon ribbons, resulting in inconsistent printing depths, which greatly reduces the printing effect and reduces the printing effect of the existing barcode printers. Not only that, in After a long time of use, the print head is scrapped due to wear and tear, and the existing barcode printer needs to be replaced manually after the print head is scrapped. During the waiting time for the manual replacement of the print head, the existing barcode printer will not be able to continue to work. The printing efficiency of some barcode printers is greatly reduced
