Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing machines, in particular to an ink-scraping mechanism for a gravure printing machine. Background Art

[0002] The gravure printing machine is mainly used for surface pattern printing on roll decorative paper, and is particularly suitable for decorative materials such as furniture, flooring and decorative wood boards. During the printing process, the pattern roller rotates while contacting the ink in the ink cartridge, so that the surface of the pattern roller can be coated with ink. The ink remains in the concave holes on the surface of the pattern roller. With the extrusion of the embossing roller, the ink in the holes can be transferred to the surface of the material, thereby achieving the effect of printing on the material.

[0003] According to the patent with announcement number CN215662398U, an ink scraping device of a gravure printing machine is proposed. The ink scraping device of the gravure printing machine can scrape off the ink other than the holes on the pattern roller by pressing the scraper against the pattern roller. The scraping effect of the ink can be adjusted by adjusting the pressing degree between the scraper and the pattern roller, which is beneficial to reduce the adhesion of excess ink on the pattern roller. The end of the scraper is inserted into the limiting hole of the limiting block so that the two ends of the scraper can be adjusted to the same distance at the same time during adjustment, thereby reducing the situation where the pressing degree between the scraper and the pattern roller is different at different positions after adjustment, thereby reducing the situation of uneven scraping of the pattern roller. The scraper is in contact with the outer wall of the pattern roller through the scraper strip. Since the scraper strip and the scraper are detachable, it is convenient to replace the damaged scraper strip after long-term use.

[0004] However, the ink scraping device of the gravure printing machine is easy to wear out because the ink scraping blade is in close contact with the pattern roller, and it is troublesome to replace the ink scraping blade, which reduces the practicality of the ink scraping device and does not meet the user's use needs. Therefore, a gravure printing ink scraping mechanism is proposed to solve the above problems. Utility Model Content

[0007] The replacement mechanism includes an embossing roller, both ends of which are rotatably connected to the inner wall of a housing of a gravure printing machine, an electric telescopic rod is fixedly installed on the top of the housing of the gravure printing machine, and a mounting shell with both ends penetrating and extending to the outside thereof is fixedly installed on the bottom of the telescopic shaft of the electric telescopic rod, and two outer shells are fixedly installed on the front of the mounting shell, and a retractable roller with one end penetrating and extending to the inside of the mounting shell is rotatably installed on the inner walls of the two outer shells, and an ink scraper is fixedly wound on the outer surfaces of the two retractable rollers.

[0008] Furthermore, the fixing mechanism includes a fixing shell, and the top of the fixing shell is fixedly connected to the bottom of the mounting shell.

[0009] Furthermore, the left and right side walls of the inner cavity of the housing of the gravure printing machine are both provided with slide grooves, and the inner surfaces of the two slide grooves are slidably connected to the outer surface of the mounting shell.

[0010] Furthermore, a motor is fixedly mounted on the inner bottom wall of the mounting shell, and an output shaft of the motor is fixedly connected to two worm shafts via a coupling.

[0011] Furthermore, worm wheels are fixedly mounted on the outer surfaces of the two retractable rollers, and the outer surfaces of the two worm wheels are respectively meshed with the outer surfaces of the two worm shafts.

[0012] Furthermore, guide rollers are fixedly mounted on the inner walls of the two outer shells, and opposite sides of the two guide rollers are respectively in the same horizontal direction as the left and right sides of the fixed shell.

[0013] Furthermore, an electric lifting rod is fixedly installed on the front side of the fixed shell, and a pressure plate is fixedly installed on one end of the lifting shaft of the electric lifting rod.
