Quick cleaning device for printing color group

Abstract

The invention provides a quick cleaning device for a printing color group. The quick cleaning device mainly comprises a drawer type ink tray and a tray locking mechanism; a scrapping cutter which is obliquely forwards extended is arranged at the front end of the drawer type oil tray; the tray locking mechanism is arranged above a backing direction of the drawer type oil tray; the tray locking mechanism comprises two fixed blocks which are fixedly connected with a left side plate and a right side plate, a coupling shaft that is rotatably connected between the two fixed blocks, a rotary propping part which is fixedly sleeved on the coupling shaft, and a locking structure for fixing the rotary propping part; and the rotary propping part can be downwards rotated, and is used for pushing the drawer type ink tray to forwards move under the effect of a lever. Compared with the prior art, the quick cleaning device for the printing color group, provided by the invention, is easy to disassemble, convenient to clean, and capable of greatly reducing the workload in cleaning of the printing color group.

Description

technical field [0001] The invention relates to the field of printing machinery, in particular to a quick cleaning device for a printing color group of a rotary printing machine. Background technique [0002] In a rotary printing machine, the printing color group is used to supply ink, which includes a left plate, a right plate, an ink tank, and an ink supply metal roller, an ink transfer rubber roller, and an ink transfer metal roller arranged in sequence along the ink transfer direction. The top of the color group also includes a plurality of ink distribution rollers and a plate cylinder at the front end. When the printing color group is used for a long time, more residual ink will accumulate on the ink transfer metal roller, and the ink transfer performance of the ink transfer metal roller will be affected after the residual ink dries. Therefore, a cleaning device is usually arranged on the printing color group to clean the surface of the ink transfer metal roller to rem...

AI Technical Summary

Problems solved by technology

[0004] But, because in the cleaning device of printing color group in the prior art, described cleaning rod is difficult to take off from printing color group easily, if take off, then must whole printing color group be disassembled from printing machine and then take out cleaning rod again.

Therefore, over time, a lot of dried residual ink has accumulated on the cleaning rod, which makes it difficult to clean the cleaning rod itself and increases the cleaning workload.

Due to the above defects, the cleaning device of the printing color group in the prior art cannot be cleaned in time, and it is difficult to meet the clean and hygienic requirements of the printing machine equipment
