Abstract

The invention relates to a high-accuracy scraper device for an electronic shaft printer. The high-accuracy scraper device for the electronic shaft printer is characterized by comprising a stand column, a linear bearing, a linear guide rail, an overall bridge type platform and the like. The high-accuracy scraper device for the electronic shaft printer provided by the invention is stable in structure and good in rigidity as a whole; for the overall movement of a scraper, the scraper device lifts up and down through the linear guide rail, the gap is small, the accuracy is high, the scraper movesstably, the scraper device flexibly moves left and right through the linear bearing, the left-and-right movement of the scraper device is controlled through a motor and is changed along with the change of the printing speed, the scraper moves up and down through a worm wheel and a worm, and the scraper is adjusted front and back through a screw rod so as to be adjusted in three directions, so thatthe influence of a gear rack gap on the stability of the scraper is reduced; and by adopting air suction assistance of the lower ends of double air cylinders, the overall scraper lifts up easily andflexibly.

Description

technical field [0001] The invention belongs to the technical field of printing machinery, in particular to a high-precision scraper device for an electronic shaft printing machine. Background technique [0002] The scraper device is an important part of the gravure printing machine. The scraper device in the prior art has complex structure, high equipment cost, inconvenient installation and adjustment, high labor intensity for workers, and affects production efficiency. The scraper clamping mechanism of the existing printing machine is that the upper and lower clips are connected and pressed by a row of bolts. It is inconvenient to replace the blade and it is not easy to operate. The structure of the invention is stable, and the overall movement of the scraper is through the linear guide rail to move left and right and lift, reducing the impact of the rack and pinion gap on the stability of the scraper, and adding double cylinders to assist lifting, so that the integral scr...
