Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing presses, in particular to an ink recycling device for gravure printing presses. Background Art

[0002] Ink is one of the core materials in the gravure printing process. It directly determines the color, clarity and quality of the printed product. The ink tank of a gravure printing machine usually has a certain depth to meet the storage and supply needs of the ink. During the printing process, the ink will flow in the ink tank and contact the printing plate roller. Therefore, the ink in the ink tank may contain impurities such as paper fibers, dust, dried ink particles, etc., which need to be recycled.

[0003] The existing gravure printing machine ink recovery and utilization device is prone to clogging the filtering equipment, resulting in reduced filtering efficiency or even malfunction. On the other hand, the viscosity and fluidity of the ink in the ink tank will change during use, and may become more viscous or uneven, which increases the resistance of the ink when passing through the filtering device, making it difficult to filter and recover smoothly, resulting in the problem of slow ink filtration speed.
