Description

Technical Field

[0001] The utility model relates to the technical field of water-based printing machines, in particular to an ink leveling device for a water-based printing machine. Background Technique

[0002] A water-based printing machine is an environment-friendly printing device that uses water-based ink as a printing medium. When the water-based printing machine is performing printing work, an ink transfer component is required to conduct the water-based ink to the printing roller. During the ink transfer process, an ink leveling device is usually installed to make the water-based ink more evenly transferred to the printing roller and ensure the printing quality of the printing machine.

[0003] The existing published patent number is (CN 221339915 U), which discloses an ink leveling device for a water-based printing machine, including a housing. A ink transfer roller is arranged at a position close to the bottom between the two sides inside the housing. A printing roller is arranged below the ink transfer roller. A fixed groove is arranged above the ink transfer roller inside the housing. A uniform coating roller is arranged between the two sides inside the fixed groove. By arranging a uniform ink coating component at the top end inside the housing, when using the printing machine for printing work, the fixed groove is pushed down by an electric push rod, and at the same time, the uniform coating roller and the silica gel sleeve arranged outside it are pushed into contact with the surface of the ink transfer roller. At the same time, the stable guide rod slides up and down in the positioning sleeve to stabilize the fixed groove and the uniform coating roller. When the ink transfer roller rotates, it drives the uniform coating roller to rotate relative to it, so that the ink on the ink transfer roller is more uniform, and at the same time, it will not cause wear to the ink transfer roller and affect its ink transfer effect, thereby further improving the ink leveling effect and being safer. However, in the actual use process, it is not easy to protect the two sides of the printing roller from dust. During the use of the printing roller, dust is likely to enter the printing machine from both sides of the printing roller, and the dust collection filter area in this device is not easy to disassemble and clean. Therefore, we introduce a new ink leveling device for a water-based printing machine. Summary of the Utility Model

An installation cylinder 7 is installed in the middle of the front end of the housing 1. A printing roller 6 is installed at the lower end of the housing 1. Shafts 5 are fixedly connected to the left and right ends of the printing roller 6.

[0027] In this embodiment, the dust-proof net 8 includes filter net plates 81. There are two filter net plates 81. Semi-circular grooves 85 are opened at the lower parts of the opposite ends of the two filter net plates 81. Support blocks 82 are fixedly connected to the front upper part of the upper end of the front filter net plate 81 and the rear upper part of the upper end of the rear filter net plate 81 respectively. Plug rods 83 are fixedly connected to the upper and lower parts of the rear end of the front filter net plate 81.
