Relationship between printing equipment and printing products

With the continuous development of the printing industry, people have higher and higher requirements on the quality of printed products, and the quality of printing products directly affects the quality and timeliness of printed products. Gansu Daily Newspaper Printing Center's printing equipment includes laser phototypesetting workshop photosetters, film developers, platemaking workshop printing machines, PS version of the development machine, printing press workshop rotary machines and auxiliary equipment. If the maintenance of the equipment in the laser photocopying workshop is not in place or the equipment fails, film waste will be caused, which will directly affect the quality of the sub-target; if the equipment maintenance of the plate making workshop is not in place or the equipment fails, the PS version will be wasted and will be directly affected. The quality of its sub-targets; equipment maintenance in the printing press workshop is not in place or equipment failure, will cause waste of paper or even directly affect the quality of the printing center. Gao Baoluolan and other advanced printing presses of Gansu Daily Newspaper Printing Center have high automation, high printing speed, and good product quality. However, as the service life increases, the degree of wear and damage to the equipment also increases. In addition to natural wear, some parts are accelerated wear and damage due to poor equipment operating conditions. If the normal maintenance and maintenance of the printing press cannot be performed normally, the technical performance of the equipment will be reduced, thereby reducing the printing quality. Therefore, with good maintenance of the printing equipment, the application rate of the equipment can be increased, the printing quality and production can be ensured, and unnecessary losses caused by improper maintenance can be reduced.

The following points fully explain the importance and necessity of equipment maintenance:

First of all, in the oil circuit, the lubrication of production equipment is an important part of the equipment maintenance work. Keeping the printer's oil path open is a matter of lubrication of the moving parts of the entire machine. It is necessary to regularly replace the oil and clean the oil filter device so that the oil flowing into the pipe does not contain impurities and block some of the oil lines. In particular, the needle roller bearing of the unit supporting the roller, if there is no lubrication and cooling of the oil, will cause long-term dry friction between the bearing and the roller shaft. When an abnormality is found, the shaft and the inner ring of the bearing have been glued, and the lighter one replaces the inner ring. The shaft is badly damaged.

Secondly, from the mechanical point of view, only the equipment operators will strengthen the maintenance and maintenance, so that the mechanical moving parts of the machine will remain clean and lubricated and operate flexibly so that the technical performance of the equipment can be fully utilized and the equipment can be kept intact. If the personnel on the platform understand this, they will always be diligently maintained and kept clean, and the accumulated ink on the machine will be removed in time, which will reduce the maintenance rate of the machine. This will not only reduce downtime, increase production efficiency, but also save on the replacement cost of spare parts.

Again, electrical aspects must be maintained. Sometimes too much dust accumulates at the relay contacts inside the electrical control box of the machine, causing poor contact of the relay contacts and rendering the machine inoperable. There are many other similar problems, such as excessive accumulation of dust in the motor will affect the movement and reset of the carbon brush holder, and affect the pressing force of the spring on the carbon brush on the carbon brush holder, so that the carbon brush and the copper head of the commutator are in poor contact. , can also cause the machine to operate difficult.

Finally, in the aspect of the gas path, the actions of the ink roller, the water roller, the separation plate, and the ink transfer roller of the printing press are realized by controlling the piston movement of the cylinder. Sometimes, due to water in the control valve or in the cylinder, the valve seal is damaged, which may cause the control valve or cylinder to leak, making the ink roller and the water roller from the plate unfavorable. In addition, since the ink accumulates in the motion control mechanism, the movement of these moving parts is inflexible, which in turn increases the burden on the control valve and the air cylinder, resulting in a fragile control valve seal. In addition, due to the aging of the gas pipeline hose, the pipeline leaks, and the pipeline pressure drops rapidly, making the control valve unable to open, and the clutch pressure action cannot be completed. If you increase the pressure, the life of the machine will be shortened. All these problems are caused by poor maintenance. Therefore, it is very important to strengthen maintenance and do daily, weekly and monthly maintenance. It will not only extend the service life of the machine, but also increase the production efficiency.

The above-mentioned supervision and inspection of the Maintenance and Equipment Division is inseparable. Being diligent in checking and killing hidden dangers in the cradle is a magic weapon to ensure the normal operation of the equipment. Fast maintenance is an advantageous guarantee for printing time efficiency, and excellent technology is the premise of maintenance equipment. Therefore, in peacetime work, we must constantly learn new knowledge, continuously accumulate experience, and improve equipment management and maintenance capabilities so that we can continuously improve the availability of equipment and ensure the timeliness and quality of prints.
