As the heart of printing machine, ceramic anilox roller is a good substitute for chrome plated metal anilox roller. It has incomparable advantages, such as quantitative ink transfer, uniform ink layer, clearer dot printing, metal anilox roller and scraper more wear-resistant. On the one hand, the metering function of the grid roller table is that the ink load can be determined by changing the number of lines of the roller; On the other hand, for the same number of lines, different ink load can also be obtained by changing the hole depth or the ratio of the hole opening to the screen wall.
Many people do not know the difference between daily cleaning and periodic cleaning of ceramic anilox roller,now I’d like to share with you:
Daily cleaning: the machine can be shut down only after the ink circulation is cleaned with clean water every day. After the machine is started, the anilox roller must be cleaned immediately. The ink screen is not easy to clean in time. Once you find that the amount of ink drop, leakage, uneven ink and density drop, this should be the relationship between the roller blockage or improper cleaning. If blockage is found locally, steel wire brush and special anilox roller cleaning agent shall be used for brushing. Stainless steel wire brush for ceramic anilox roller shall be stainless steel wire brush with diameter less than 0.076 mm, otherwise the steel wire is too thick to extend into the mesh. At the same time, when using the wire brush, 360 degree circle brush must be used so that the steel wire can turn into the bottom of the mesh. There are many kinds of special cleaning agents and different cleaning effects. It is better to consult the anilox roller manufacturer or ink supplier when purchasing.
Periodic cleaning: due to the large resin particles of water-based ink, and the drying speed of water-based ink is fast, many times because the operators of the carton factory do not clean in time, the bottom of the mesh will slowly dry and block. The normal carton factory must arrange a thorough cleaning and maintenance of the anilox roller within two months. Due to the long size of carton printing roller and inconvenient disassembly and assembly, it is generally selected to clean directly on the machine. A layer of special Super softener for anilox roller is evenly applied on the surface of ceramic roller, wrapped with film, fully dissolved for 20 minutes, then cleaned with steel wire brush and then cleaned with water. If some parts are not cleaned, they can be cleaned several times. Pay attention to protect the offset and cots at the same time. The frequency of periodic cleaning can be reduced if the normal daily cleaning work is well done. At present, many high wire anilox rollers are seriously jammed, so we can choose to remove the anilox roller for ultrasonic cleaning, or our company can provide on-line laser cleaning service (the cost is relatively high).
The above is the difference between daily cleaning and periodic cleaning of ceramic anilox roller, hoping to help you understand.
