Maintenance method of corrugated carton printing machine
1. Establish rules and regulations for machine maintenance. The maintenance of the offset printing machine should be based on the instruction manual of the machine. Such as regular oil change, filter cleaning, regular inspection of machine accuracy, etc.
  2. Strengthen the maintenance of important parts. Gears, cams, sprockets, rollers and bearings are the most important parts on a printing press, and their maintenance is different from other parts, because changes in their accuracy will affect the final print quality. Springs are the most used parts for force balancing mechanisms on machines. The quality of their work directly determines the precision of the mutual cooperation of moving parts. extremely unfavorable. If the above problems are found, the springs need to be replaced immediately.
3. Carry out technical reforms and strengthen machine maintenance. Machine maintenance requires the convenience of machine maintenance to be fully considered when the machine is designed. However, due to the complexity of the printing machine, it is obviously impossible to take every factor into account, and the content of machine maintenance will also change as the environment changes. Therefore, it is necessary to improve those structures that are not conducive to machine maintenance without affecting normal work.
Second, the dynamic maintenance of carton printing machine
The dynamic maintenance of the carton printing machine refers to the maintenance of the machine when the printing press is in motion. The static maintenance of the machine is the premise of the dynamic maintenance of the machine, and the dynamic operation of the machine can in turn detect the level of the static maintenance of the machine. The dynamic maintenance of the machine is very important.
The main contents of the dynamic maintenance of the carton printing machine are:
  1. Machine readiness detection. The readiness of the machine can be detected by jogging or cranking. For example, tools and other items are stuck in the machine; whether the installation position of the printing plate is suitable, if not, it may damage the printing plate or bring great difficulty to finding the rules; whether the blanket is installed properly, if not, it is possible Cause printing failure, and may damage the blanket or machine in severe cases.
  2. The lubrication state of the machine. First of all, you can check whether the oil circuit of the machine is smooth through the oil mark. If there is no oil on the oil mark or the oil mark is not clearly visible, you should stop in an emergency and carefully check whether there is oil leakage in the oil circuit. Oil leaks from machines, while easy to observe, can be difficult to find out about. For machines such as sliding bearings, low speed is not conducive to its lubrication, especially jogging or low-speed operation has a greater impact on its lubrication. Therefore, before such operations, it is best to idle the machine and lubricate it, which is also the first task that should be done before going to work. The oil pump of some machines is driven by the main engine, so when the reverse point occurs, the oil circuit will not only be unable to refuel, but will suck the oil in the oil circuit back to the fuel tank, which is very dangerous, so the reverse point should be avoided. The lubrication of some more important parts can also be detected by the temperature of the metal nearby. If the temperature is too high, it indicates that there is a problem with the lubrication.
3. Shock during machine operation. The smaller the impact during the operation of the machine, the more conducive to printing, and also prolong the service life of the machine. Reducing the printing pressure (pressure in a broad sense) is an important condition to ensure the smooth operation of the machine. On the premise of ensuring the quality of the printed product, the smaller the printing pressure, the better. Reducing the speed of the machine is another important condition for reducing 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 running at high speed. The above aspects are only part of the daily maintenance and maintenance of the printing press. The quality of the daily maintenance and maintenance of the printing press directly affects the service life and product quality of the printing press, so it should not be taken lightly.
