Printing machine daily maintenance, it is necessary to know the six key problems!

Printing machine daily maintenance, it is necessary to know the six key problems! Printing machine daily maintenance, it is necessary to know the six key problems!

printing machine maintenance is divided into daily maintenance, weekly maintenance, monthly maintenance, quarterly maintenance, annual maintenance, etc. , which day is every day to do maintenance, the maintenance of the purpose is to prolong the service life of equipment, indirect companies use cost saving. At the same time, for some printing equipment maintenance can also play the role of to avoid production accident. A not often maintenance of equipment, it is easy to major accidents are caused by damage of local parts. This article is to introduce the printer daily maintenance of six key problems.

here are the printing machine maintenance of several big key:

a, pressure roller printing pressure roller is not clean, printing pressure in the process of production is not uniform. For the common case of pressure roller on tape or dry solid ink, so that the height of the pressure roller will be high, resulting in printing pressure increases. Common is printing the fuzzy quality accident, the article or design is not clear. So the pressure roller must ensure clean.

2,

plate plate cylinder is not clean, will affect the print pressure in the process of production and printing pressure, often have tape and dry ink, bump phenomenon and liner. This production will directly increase the height of the print, lead to inconsistent print height, cause printing blurred, points not clear, virtual shadow phenomenon, etc.

3, the axis and screw

bearings and screw mainly slotting unit and feeding unit, the screw is not clean regularly, bearing is easy to damage, and thus affect the screw and the bearing's life and production of precision. Such as line pressing bearing is prone to vibrate, often without oil shock after the bigger carton line pressing can produce line or line pressing the phenomenon such as false. Wire rod and bearing maintenance is one of the most important step.

4, rail to rail cleaning is the most easy to forget, if the printer to track not clean for a long time, will affect the parallelism of the printing unit. Sets unparallel rail directly affect printing precision, so the high-end printing machine of rail demand is very high. So the rail must be cleaned every day.

5, the anilox roll and refill tube surface

anilox roll is the heart of the printing press, if you don't clean anilox roll, thief will cause printing, color is not consistent, so the anilox roll should be carried out daily cleaning and maintenance, rather than block again after maintenance work. Anilox roll maintenance is daily maintenance, daily should take when do not use the anilox roll version washing liquid or washing powder for circulation water clean, do the daily clean, so as to ensure the printing quality.

6, machine and ground surface cleaning

above equipment cleaning is the biggest impact of the outage cha version and print the thief, a lot of factory equipment surface is very clean, but the equipment and the ground is full of dust. The dust will be in the process of production into the ink or print at any time, lead to stop printing and printing the phenomenon such as the thief.

editorial

printing machine daily maintenance is just one part of the six aspects, then according to the different equipment for different methods of equipment maintenance, equipment maintenance good, not the length of time a printer will increase, equipment maintenance will reduce downtime, printing will improve efficiency at the same time, the quality of the product can also be improved and the stability.
