Description

To open offset press cylinder cleaning device

Technical Field

The utility model belongs to the technical field of lithography apparatus, concretely relates to offset press cylinder cleaning device.

Background

The offset press is one kind of lithographic plate press, and during printing, the printed image and text is first printed onto rubber cylinder from the printing plate and then transferred onto paper with the rubber cylinder. The impression cylinder is a cylindrical impression body on a printing press and serves as an adjustment reference for supporting sheets, transferring sheets, completing printing and other mechanical relationships of the parts. In the working process, an impression cylinder on the offset press is in pressure contact with a rubber cylinder, the impression cylinder is stained with ink, water, dust and other stains, and especially when a split offset press is used for printing six-split or four-split paper, the stains on the part, which is not covered by the paper, of the impression cylinder are serious. The dirt adhered on the impression cylinder is easy to corrode the impression cylinder, and the ink is easy to harden and crystallize on the surface of the impression cylinder, so that the impression cylinder is difficult to clean.

In the prior art, publication number is CN 206124456U's patent application discloses an impression cylinder cleaner, including the support frame that semicircular groove was seted up to the side, the support frame inner wall is provided with the one deck cleaning brush, and the support frame both ends symmetry is provided with the connecting rod of L shape, and the equal fixedly connected with open-top's semicylindrical axle journal bracket in upper end of two connecting rods, and two axle journal brackets are coaxial with the semicircular groove of support frame. The cleaner rotates the impression cylinder by taking the shaft neck bracket as a support frame, and the cleaning brush on the inner wall of the support frame is utilized to clean ink on the impression cylinder. However, when the cleaner is used, the impression cylinder needs to be taken off from the offset press, and the cleaning brush is coated with gasoline to clean the ink on the impression cylinder, so that the impression cylinder needs to be disassembled and assembled every time cleaning is carried out, and the operation is complex.
