Cardboard box printing grooving machine printing unit single scraping cutter device

Abstract

The invention particularly relates to a single scraper apparatus of a printing unit of a carton box print fluting machine, wherein an ink cavity of the single scraper is installed on a bracket by an articulated mechanism, and the scraper and a spacer are fixed on the ink cavity of the single scraper by a pressure plate and screws; a spring gauge is fixed on the bracket; one end of a spring rod is provided with threads, and the other end of the spring rod is a discoid fillet; the thread end of the spring rod is installed in the bolt hole of the ink cavity of the single scraper; a spring is installed between the spring gauge and the discoid fillet of the spring rod. A closing board at a nylon end and a closing board at an elastic end are respectively installed at both ends of the ink cavity of the single scraper; the ink cavity of the single scraper, the scraper, the closing board at the nylon end, the closing board at the elastic end and an air bag are installed between the ink cavity of the single scraper and the bracket. By adopting the technical scheme, an anilox roller can not be scratched, the ink can be recycled in the ink cavity, and the ink can be recovered and cleaned, which can save cleaning water, decrease pollutions of cleaning and decrease the cost of water treatment.

Description

Technical field: [0001] The invention relates to the technical field of carton printing machinery, in particular to a carton printing and slotting machine printing unit single scraper device with a scraper. Background technique: [0002] There are two traditional scraper devices for carton printing and slotting machines with scrapers: one is double scrapers, and the other is single scraper without seal. The double scraper device is composed of a lower scraper and an upper sealing knife. The edges of the upper sealing knife and the lower scraper are closely attached to the surface of the anilox roller when the machine is working. , will stick to the surface of the anilox roller, because the upper sealing knife is close to the surface of the anilox roller, the small granular objects pasted on the surface of the anilox roller will be blocked by the upper sealing knife, and the small granular objects will be It will be sandwiched between the upper sealing knife and the anilox r...

AI Technical Summary

Problems solved by technology

The double scraper device is composed of a lower scraper and an upper sealing knife. The edges of the upper sealing knife and the lower scraper are closely attached to the surface of the anilox roller when the machine is working. , will stick to the surface of the anilox roller, because the upper sealing knife is close to the surface of the anilox roller, the small granular objects pasted on the surface of the anilox roller will be blocked by the upper sealing knife, and the small granular objects will be It will be sandwiched between the upper sealing knife and the anilox roller, and the anilox roller will be scratched. After the anilox roller is scratched, it will affect the ink of the printing plate and affect the printing effect

Unsealed single scraper device, no upper sealing knife, and no ink chamber formed, the pumped ink cannot stay between the scraper and the anilox roller for a short period of time, and directly flows into the connection through the two ends of the scraper and anilox roller. In the ink tray, the ink cannot be fully utilized during a pumping process; also due to the above reasons, the ink stuck on the surface of the ink tray, ink return pipe, rubber roller, and anilox roller is easy to dry up, which will cause machine pollution , cleaning the pollution will bring pollution to the site

Also, because there is no seal and the ink chamber cannot be formed, it is impossible to recover the ink remaining on the surface of the rubber roller and anilox roller after printing, and the water consumption is more when cleaning.
