Abstract

The invention discloses a sealing device for jacking and rotating of a printing plate cylinder. The sealing device comprises a mandrel matched with the printing plate cylinder in specification, a jacking cock and a moving sleeve are arranged outside the mandrel in a sleeved manner, the jacking cock is connected together with the mandrel through a tensioning ring and a supporting screw, a ferrule is arranged outside of the moving sleeve, an ink blocking component is arranged between the jacking cock and the moving sleeve and on the outer surface of the mandrel and composed of an ink blocking ring a, an ink blocking ring b and an ink blocking ring c, the ink blocking ring b is fixed to the moving sleeve through a fastening screw, the ink blocking ring a and the ink blocking ring c can rotate in the ink blocking ring b, a sealing ring, a bearing and a combined splicing cap are arranged between the moving sleeve and the mandrel, the sealing ring is bowl-shaped and is connected with the ink blocking component, and two ends of the bearing are connected with the sealing ring and the combined splicing cap respectively and spliced tightly through the combined splicing cap. Through the combined ink blocking component and the sealing ring which are durable, splashing ink is effectively prevented from constantly seeping into the bearing in the sleeve, so that the sealing device has good ink-blocking sealing effect.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for pressing and rotating a printing plate cylinder. Background technique [0002] When the printing plate cylinder in the printing machine is rotating tightly, in order to prevent the splashed ink from continuously penetrating into the bearing of the rotating shaft in the sleeve, an ink blocking and sealing device must be provided. The existing ink retaining device is usually a single ink retaining ring structure, and the ink retaining device of this structure is affected by factors such as wear and tear, and the ink retaining effect is poor, which in turn affects the sealing effect. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a sealing device for pressing and rotating the printing plate cylinder, which is provided with a durable combined ink retaining component and a sealing ring, a...
