Problems solved by technology
[0003] The technical problem to be solved by the present invention is that during double-sided printing, if the printing time of the front side and the back side is short, it will cause the previous printing ink to be pressed on the printing plate cylinder in the latter printing process, forming ink marks, which is easy to repeat when printing again. Embossing, so that the embossed side of the paper in the subsequent printing process is accompanied by excess ink marks, the purpose is to provide equipment for reducing ink pollution during double-sided printing, and solve the above problems

The invention discloses equipment for reducing ink pollution during double-sided printing and relates to a double-sided cylinder round printing press. The equipment for reducing ink pollution during double-sided printing comprises a printing unit arranged in a printing machine shell and further comprises a quick-dry cleaning device. The quick-dry cleaning device is arranged in front of a positionwhere paper to be printed enters a reverse side impression cylinder and between the paper to be printed and the reverse side impression cylinder. The quick-dry cleaning device comprises a hollow inserting and pulling device, an ink suction device and a blower device. The hollow inserting and pulling device comprises a hollow through rod and a coordinating rod which are coaxially arranged. According to the equipment, the quick-dry cleaning device can be installed on the printing machine only by perforating the side wall to form a hole, and the equipment has the beneficial effect of being high in generalization; by means of the ink suction device, the cleanliness of impression cylinders is kept; and the impression cylinders can impress less ink as much as possible, and ink accumulation is reduced at a source.
Description
technical field [0001] The invention relates to a double-sided rotary press circular printing machine, in particular to equipment for reducing ink pollution during double-sided printing. Background technique [0002] When performing double-sided printing, since the other side is printed in a short time after printing one side, the drying time of the ink is extremely short, so most double-sided printing machines have the problem of ink sticking and ink accumulation on the surface of the impression cylinder. The existing technology usually uses special magnetic sheath and super blue cloth, because the surface of these two materials is uneven and the materials used on the surface have certain ink resistance. However, in actual use, it can still be found that after the printing machine has been working for a period of time, ink pollution on one side will occur, which will affect the printing efficiency and cause waste. Contents of the invention [0003] The technical problem ...
