The following introduces the key points of printing press maintenance:
1.pressure roller
The pressure roll of the printing press is not clean, and the printing pressure is not uniform during the production process.A common situation is the adhesive tape or dry solid ink on the pressure roller, so that the height of the pressure roller will become higher, resulting in increased printing pressure.Quality accidents are common is fuzzy printing,articles or patterns are not clear.So the pressure roll must be kept clean.
2. printing roller
Printing roller is not clean, the production process will affect the printing pressure and printing pressure, common conditions are tape and dry solid ink, and a bump on the cushion.Such production will directly increase the height of the printed version, leading to the inconsistent height of the printed version, causing fuzzy printing, unclear outlets, virtual phenomenon and so on.
3. Axis and silk rod
The bearing and wire rod are mainly grooved units and paper delivery units. If the wire rod is not often cleaned and refueling, the bearings are easily damaged, thus affecting the life of the wire rod and bearings and the precision of production.If the pressure line bearing often does not refueling is easy to produce vibration, vibration becomes large after the carton line will produce burst line or line and other phenomenon.The maintenance of silk rods and bearings is an important link for the.
4. the ground rail
The cleaning of the ground track is easy to ignore, if the printing machine ground track * is not clean, it will affect the parallelism of the printing unit.The unit is not parallel to the ground rail directly affects the printing accuracy, so the printing press has very high requirements on the ground rail.So the earth rail must be cleaned up daily.
5. Surface of the mesh roller and the ink pipe
The roller is the heart of the printing press, if the roller is not clean, it will cause printing white, color inconsistency and other phenomena, so the roller must be cleaned and maintained daily, rather than blocked after maintenance.Mesh roller maintenance is daily maintenance, daily in the use of mesh roller should take washing liquid or washing powder water circulation cleaning, do daily cleaning, so as to ensure the printing quality.
6. Clean the machine surface and the ground above
Equipment cleaning impact is the shutdown coating and printing white, many factory equipment surface is very clean, but the equipment and the ground is dust everywhere.This dust will enter the ink or printing surface at any time during the production process, resulting in printing shutdown and printing whitening phenomenon.
After the language
Printing press daily maintenance this 6 aspects is only part of them, then according to different equipment to develop different equipment maintenance methods, equipment is not maintained, printing press shutdown time will increase, equipment maintenance good downtime will reduce, printing efficiency will improve at the same time,the quality of the product can also be improved and stable.
