Description

Roller frame end cover structure of transmission side ink distributing roller

Technical Field

The utility model relates to a roller frame end cover structure of transmission side ink distributing roller belongs to lithography apparatus technical field.

Background

The inking device of the printing machine is composed of an ink supply part, an ink uniformizing part and an inking part. The ink distributing roller of the ink distributing part is important for realizing uniform ink distribution, and the ink distributing roller rotates at a high speed and simultaneously axially reciprocates in an ink distributing process to enable ink to be uniformly printed on a printing stock. The oscillating roller needs to rotate at a high speed and oscillate axially and reciprocally, so that the maintenance and the replacement of the oscillating roller are frequent.

In order to facilitate the disassembly and the assembly and the replacement, the Heidelberg ink vibrator adopts a three-section structure and comprises a roller body, a transmission side ink vibrator detachably connected to one end of the roller body and an operation side ink vibrator detachably connected to the other end of the roller body. Wherein, the dress is worn respectively in printing machine frame both sides to transmission side ink vibrator and operation side ink vibrator, and transmission side ink vibrator front end is in the frame outside, and the rear end is then inboard in the frame to transmission side ink vibrator front end is installed the ink vibrator pull rod, drive gear subassembly etc. and the rear end installation is leaned on the version ink roller frame, installs the ink roller axle sleeve in the mounting hole department that leans on the version ink roller frame, leans on version ink roller seat, leans on parts such as version ink roller, and the ink roller axle sleeve is close to frame inboard department and is equipped with the jump ring, the jump ring is used for the ink roller axle sleeve and leans on the connection between the version ink roller seat spacing, and leans on version ink roller frame to fix in the frame inboard through its rear. At present, the hardness of ink roller shaft sleeve is less than by version ink roller seat, and the long-term back of working of ink vibrator for ink roller shaft sleeve wearing and tearing are serious, have increased ink roller shaft sleeve and have leaned on the fit clearance between the version ink roller seat, lead to installing and lean on the version ink roller seat that the version ink roller appears the cluster to move, seriously influence printing quality.

However, the rear end of the transmission side ink distributing roller is provided with an installation boss connected with the roller body, and the end cover and the installation bolt close to the rear end of the plate ink roller frame cannot be taken down due to the blockage of the installation boss, so that the ink distributing pull rod, the transmission gear assembly and the like can be only removed from the front end of the transmission surface shaft in sequence when the ink roller shaft sleeve is replaced, and then the clamp spring at the rear end of the ink roller shaft sleeve can be taken out and replaced. The ink distributing pull rod, the transmission gear assembly and the like are difficult and cumbersome to disassemble, and a large amount of labor and time are wasted during replacement, so that the ink distributing pull rod and the transmission gear assembly are very inconvenient.
