Maintenance of printing press

Printing press is one of the most efficient equipment in printing plant. To ensure the normal operation of the printing press, daily maintenance and maintenance is essential and very necessary. Below from the following aspects to talk about the daily maintenance and maintenance of the machine.

Static maintenance

Static maintenance of printing press refers to the maintenance of the machine in a static state.

1. Establish rules and regulations for machine maintenance. The maintenance of an offset press shall follow the instructions of the machine. Such as regular oil change, filter cleaning, regular detection of machine accuracy.

2. Strengthen the maintenance of important parts. Gears, cams, sprockets, rollers and bearings are important parts of a printing press, and their maintenance is different from other parts, because changes in their accuracy will affect them. The spring is the machine for force balance mechanism of the parts, their work is good or bad directly determines the accuracy of the moving parts with each other, the spring must have sensitive elasticity, and elastic and unrecoverable plastic deformation is not conducive to the work of the spring. If the above problems are found, the spring needs to be replaced immediately. Hazard of solvent residue in printing process

3. Carry out technical reform and strengthen machine maintenance. Machine maintenance requires that the convenience of machine maintenance be fully taken into account when the machine is designed. However, due to the complexity of printing presses, it is obviously impossible to take every factor into account, and the maintenance of the machine will change as the environment changes. Therefore, it is necessary to improve the structure of those unfavorable to machine maintenance without affecting the normal work.

Dynamic maintenance

The dynamic maintenance of printing press refers to the maintenance of the machine under the dynamic state of printing press. Machine static maintenance is the premise of machine dynamic maintenance, while the dynamic operation of the machine can in turn detect the level of machine static maintenance. The dynamic maintenance of the machine is quite important. The following from several aspects to analyze the machine dynamic should maintain the main content.

1. Machine readiness test. The readiness of the machine can be detected by clicking or turning. Such as tools and other items stuck in the machine; Plate installation position is appropriate, if not appropriate, it may cause plate damage or bring great difficulties to find rules; Whether the rubber blanket installation is appropriate, if not, it may cause printing failure, serious may cause or damage the machine.

2. Lubrication state of the machine. First of all, you can observe whether the oil circuit of the machine is smooth through the oil label. If the oil label is free of oil or the oil label is not clear, you should stop the machine in an emergency to carefully check whether there is oil leakage. Oil leaks from machines are easy to observe, but finding their cause is difficult. For machines such as plain bearings, low speed is not conducive to its lubrication, especially the point or low speed operation has a greater influence on its lubrication. Therefore, before this kind of operation, the first idling machine lubrication, which is also a daily work should be done before the first work. The oil pump of some machines is driven by the main engine, so when the reverse point, the oil circuit not only can not fuel, but will pull the oil back to the tank, which is very dangerous, so it should avoid the reverse point. The lubrication of some important parts can also be detected by the temperature of the metal near it. If the temperature is too high, it indicates that there is a problem with lubrication.

3. Impact during machine operation. The smaller the impact during the operation of the machine, the more conducive to printing, but also to extend the service life of the machine. Reducing the printing pressure (pressure in a broad sense) is an important condition to ensure the smooth running of the machine. On the premise of ensuring the quality of the printing, the smaller the printing pressure, the better. Reducing the machine speed is another important condition to reduce the moment of inertia of the machine, the lower the speed of the machine, the smaller the moment of inertia, so the machine should not always be in high speed operation.

The above several aspects are only part of the daily maintenance and maintenance of printing press. The quality of daily maintenance and maintenance of printing press directly affects the service life and product quality of printing press, so it cannot be taken lightly.
