Patent name Ink transfer device for flexographic printing press with ink separation element Patent applicant Zhu Fagen Principal applicant Address 343200 Inventor of Anfuao Printing Film Factory, Anfu County, Jiangxi Province Patent application No. 200420073523.0 Date of application 2004.07. 06 Approval Date Approval Notice No. 2734477 Audit Notice Date 2005.10.19 Instruction CD-ROM D0542 Main Classification Number B41F31/04 Classification Number B41F31/04; B41F31/02 Sub-item Original Application No. Priority Item Abstract A kind of ink-retaining member The flexographic printing machine ink inking device includes an anilox roller, a squeegee, an ink tank and a plate cylinder. Both ends of the plate cylinder have a driving cam with the same outer diameter. The drive cams at both ends drive the anilox roller in a friction manner respectively. The driving cylinder surface at both ends is characterized in that an isolating annular groove is arranged perpendicularly to the anilox roller between the anilox roller mesh segment and the two end driving cylinder surfaces of the anilox roller. The ink in the texture section or the ink tank is prevented from being transmitted to the drive cylinder surface at both ends of the anilox roller and the ink barrier member on the drive cam at both ends of the plate cylinder. Compared with the prior art, the utility model has the advantages of novel design and simple structure, which can not only seal or semi-enclose the ink in the ink tank but also facilitate the replacement of ink color. In particular, it is possible to completely prevent the ink in the texture section or the ink tank from being transmitted to the driving cylinder surfaces at both ends of the anilox roller and the driving cams at both ends of the plate cylinder. Sovereignty item 1, a flexographic printing press ink inking device with an ink separating member, comprising an anilox roller, a squeegee, an ink tank, a plate cylinder, and both ends of the plate cylinder have a driving cam with the same outer diameter. The drive cams at both ends respectively drive the drive cylinder surfaces at both ends of the anilox roller by friction, and are characterized in that: an anilox roller is arranged between each of the anilox roller anilox roller segments and anilox roller both ends of the drive cylinder surface. A vertical, isolating annular groove is provided with a driving cylinder surface for preventing the ink in the texture section or the ink tank from being transmitted to both ends of the anilox roller and the ink barrier on the driving cams at both ends of the plate cylinder.
