Daily maintenance and maintenance of the printing machine

The printing press is the center of the printing plant, and it is also one of the highest utilization rates among all printing equipment. In order to ensure the normal operation of the printing press, daily maintenance and maintenance are indispensable and necessary. Daily maintenance and maintenance of the printing press is an important task in the management of printing equipment. Below from the following aspects briefly talk about the daily maintenance and maintenance of the machine.

First, the static maintenance of the printing press

The static maintenance of the printing press refers to the maintenance of the machine while the machine is in a static state.

1. Establish rules and regulations for machine maintenance. Offset machine maintenance should be based on the machine's instructions. Such as regular oil change, cleaning filters, regular inspection of machine accuracy.

2. Strengthen the maintenance of important parts. Gears, cams, sprocket, rollers, and bearings are the most important parts of the press. Their maintenance must be different from other parts because their accuracy will affect the final print quality. The spring is the most used component of the force balance mechanism on the machine. Their work directly determines the accuracy of the mutual motion of the moving parts. The spring must be sensitive to elasticity, while the elasticity and the non-recoverable plastic deformation are the work of the spring. Extremely disadvantageous. If you find the above problem, you need to replace the spring immediately.

3. Conduct technical reforms to strengthen machine maintenance. Machine maintenance requires the machine to fully consider the convenience of machine maintenance when designing. However, due to the complexity of the printing press, it is obviously impossible to take every factor into consideration, and the environment changes and the contents of machine maintenance will also change. Therefore, structures that are not conducive to machine maintenance should be improved without affecting normal work.

Second, the dynamic maintenance of the printing press

The dynamic maintenance of the printing press refers to the maintenance of the machine under the dynamic state of the printing press. The static maintenance of the machine is the prerequisite for the dynamic maintenance of the machine. At the same time, the dynamic operation of the machine can in turn detect the level of static maintenance of the machine. The dynamic maintenance of the machine is very important. From the following aspects to analyze the main content of the machine should be maintained under the dynamic.

1. Machine preparation status detection. How the machine is prepared can be detected by jogging or turning. Such as tools and other items stuck in the machine; whether the appropriate installation position of the printing plate, if not appropriate, may cause damage to the printing plate or make it difficult to find rules; if the blanket is installed properly, if it is not suitable, it is possible. Causes printing failures. In severe cases, the blanket or machine may be damaged.

2. The lubrication status of the machine. First, through the oil standard, you can observe whether the oil path of the machine is unblocked. If the oil mark is not oily or the oil mark is not clearly observed, you should urgently stop and carefully inspect the oil path for oil leakage. Although the oil leakage of the machine is easy to observe, it is difficult to find the reason. For a machine such as a sliding bearing, low speed is not conducive to its lubrication. In particular, the point-of-action or low-speed operation has a great influence on its lubrication. Therefore, it is advisable to idle the machine for lubrication before performing this type of operation. This is a top priority for daily work. Some machines have oil pumps that are driven by the main engine. Therefore, when they are at the opposite point, the oil line will not only be refueled, but will also suck oil from the oil line back into the fuel tank. This is dangerous, so anti-points should be avoided. Lubrication of some of the more important parts can also be detected by the temperature of the metal in the vicinity. If the temperature is too high, it indicates a problem with lubrication.

3. The impact of the machine during operation. The smaller the impact during the operation of the machine, the more conducive to printing, but also can extend the life of the machine. Reducing printing pressure (in a broad sense, pressure) is an important condition for ensuring the smooth operation of the machine. Under the premise of ensuring the quality of printed products, the printing pressure should be as small as possible. 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 is, the smaller the moment of inertia is, so the machine should not be kept at a high speed all the time.

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