Safety type printing machine

Abstract

The invention relates to a safety type printing machine. The safety type printing machine comprises a main body, a printing box, a printing device, a rotating mechanism, a cleaning mechanism and a purifying mechanism, which are arranged in the main body, the rotating mechanism comprises a first motor, a driving roller and a transmission roller, the cleaning mechanism comprises a moving unit and anisolating unit, the moving unit comprises a second motor, a screw rod, a nut, a telescopic assembly and a nozzle, the isolating unit comprises a third motor, a turntable, a fixing rope, a moving block, shielding cloth and a fixing shaft, and the purifying mechanism comprises an air extractor, a dust removal unit and a purification chamber. The safety type printing machine has the advantages thatthrough the cleaning mechanism, the printing machine can clean ink adhering to the driving roller, the surface of the driving roller is prevented from becoming smooth, so that the ink transferring performance of the driving roller is prevented from being reduced, moreover, through the purifying mechanism, the printing machine can purify poisonous and harmful gas and dust generated in the printingprocess, so that the poisonous and harmful gas and dust are prevented from affecting the air environment in a workshop, and the health of workers is ensured.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a security printing machine. Background technique [0002] A printing press is a machine that prints text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. The printing machine applies the ink to the place where there are text and images on the printing plate, and then directly or indirectly transfers it to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass and ceramics), so that Duplicates the same print as the printing plate. [0003] The ink roller of the existing printing machine will adhere to a large amount of dried ink after long-term operation, causing the surface of the ink roller to become very smooth, resulting in a decline in the ink transfer performance of the ink roller. Not only that, the existing printing machine...

[0003] The ink roller of the existing printing machine will adhere to a large amount of dried ink after long-term operation, causing the surface of the ink roller to become very smooth, resulting in a decline in the ink transfer performance of the ink roller. Not only that, the existing printing machine will , the ink needs to be heated, and the ink is very likely to produce toxic and harmful gases when heated, which affects the air environment in the workshop and endangers the health of workers
