Abstract

The invention relates to a printing guide roller capable of scraping dust. The printing guide roller capable of scraping dust comprises a rolling shaft and a printing guide roller main body sleeving the rolling shaft, wherein cylinder bearers are further arranged at the axial end parts of the printing guide roller main body; a sticking band is pasted on the peripheral surface of the printing guide roller main body; a dust scraping device is arranged at the lower end of the rolling shaft; the two ends of the dust scraping device are connected with the two ends of the rolling shaft; and the dust scraping device is always positioned at the lower end of the rolling shaft. The dust scraping device can scrape dust on the sticking band in real time, the printing guide roller main body is prevented from being stained with dust, and printing paper is prevented from being polluted by dust.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a scraping printing guide roller. Background technique [0002] Printing guide rollers, especially those used to print invoices, during long-term use, because the pattern on the printing paper is in direct contact with the main body of the printing guide roller, the printed pattern that has just come out and has not been dried and finalized is easily dragged by the main body of the printing guide roller. Dirty, which damages the pattern of the printed paper. Contents of the invention [0003] The purpose of the present invention is to provide a dust-scraping printing guide roller. The technical problem to be solved is: the printing pattern that has just come out and has not been dried and finalized is easily dirty by the main body of the printing guide roller, causing the pattern of the printed paper to be damaged. [0004] The technical solution of the present invention to so...
