Description

Technical Field

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

[0002] During the production and processing of ink, filters are often needed to filter the ink to ensure the quality of the ink. However, after filtration, the residual ink inside the filter will dry and block the filter components, and a filter that is convenient to clean is required.

[0003] The existing patent with the publication number CN211215548U and the name "Ink Filter" relates to the technical field of filtering devices and discloses an ink filter, including a filter box. A support foot is fixedly connected to the bottom of the filter box, a purification box is fixedly connected to the top of the filter box, and an activated carbon plate is fixedly connected to the inside of the purification box. In this ink filter, the ink to be filtered is poured into the filter box through a feeding funnel. The ink will fall above the filter plate. By driving the drive shaft to rotate forward or backward at a certain angle by a servo motor, during the rotation of the drive shaft, the filter frame and the filter plate will be driven to rotate in turn. During the rotation of the filter plate, the ink above the filter plate will flow through the filter holes to the upper part of the connecting plate and the fixing plate, dispersing the ink and gas, achieving the purpose of ink filtration, purifying the ink gas, protecting human health and the living environment, and improving the use efficiency and effect of the ink filter.

[0004] After the above device is filtered, the residual ink inside the filter will dry and block the filter plate, and it will also affect the quality of the ink filtered next time. Moreover, it cannot filter the magnetic impurities inside and cannot well meet people's usage requirements. In view of the above situation, technological innovation is carried out on the basis of the existing ink filter. Summary of the Utility Model
