The printing press is one of the equipment with the highest utilization rate among all the equipment in the printing factory. To ensure the normal operation of the printing machine, daily maintenance is essential and necessary. Let's talk about the daily maintenance of the machine from the following aspects.
The printing press is one of the equipment with the highest utilization rate among all the equipment in the printing factory. To ensure the normal operation of the printing machine, daily maintenance is essential and necessary. Let's talk about the daily maintenance of the machine from the following aspects.
Static maintenance
The static maintenance of a printing machine refers to the maintenance of the machine when the machine is in a static state.
1. Establish rules and regulations for machine maintenance. The maintenance of offset printing machine shall be subject to the instructions 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 of the printing press. Their maintenance should be different from other parts, because their accuracy changes will affect the final. Springs are the most widely used components in the force balance mechanism of the machine. Their work quality directly determines the accuracy of the coordination between moving components. Springs must be sensitive and elastic, while anelasticity and irrecoverable plastic deformation are extremely unfavorable to the work of springs. If the above problems are found, the spring shall be replaced immediately. Harm of solvent residue in printing process
3. Carry out technical reform and strengthen machine maintenance. Machine maintenance requires that the convenience of machine maintenance should be fully considered when designing the machine. However, due to the complexity of the printing press, it is obviously impossible to take every factor into account, and the content of machine maintenance will also change due to changes in the environment. Therefore, the structures that are not conducive to machine maintenance should be improved without affecting the normal work.
Dynamic maintenance
The dynamic maintenance of a printing machine refers to the maintenance of the machine when the printing machine is in a dynamic state. Static maintenance of machines is the premise of dynamic maintenance of machines. At the same time, the dynamic operation of machines can in turn detect the level of static maintenance of machines. The dynamic maintenance of the machine is quite important. The main maintenance contents of the machine in dynamic state are analyzed in the following aspects.
1. Machine readiness detection. The readiness of the machine can be detected by inching or turning. Other objects such as tools are stuck in the machine; Whether the installation position of the printing plate is appropriate, if not, the printing plate may be damaged or it will be very difficult to find the rules; Check whether the rubber blanket is properly installed. If not, it may cause printing failure, or even damage the machine in serious cases.
2. Lubrication status of the machine. First, you can observe whether the oil path of the machine is smooth through the oil pointer. If the oil pointer has no oil or the oil pointer cannot be observed clearly, you should stop the machine in an emergency and carefully check whether the oil path has oil leakage. Although the oil leakage of the machine is easy to observe, it is difficult to find the cause. For machines with sliding bearings and the like, low speed is not conducive to their lubrication, especially inching or low speed operation has a greater impact on their lubrication. Therefore, it is better to lubricate the idling machine before such operation, which is also a primary work to be done before going to work every day. The oil pump of some machines is driven by the main engine, so when the oil circuit is reversed, instead of refueling, it will suck the oil in the oil circuit back to the oil tank, which is very dangerous. Therefore, the reverse point should be avoided. The lubrication of some important parts can also be detected by the metal temperature nearby. If the temperature is too high, it indicates that there is a problem with lubrication. Common Troubles and Troubleshooting of Gravure Printing Gold Silver Ink
3. Impact during machine operation. The smaller the impact during the operation of the machine, the better for printing, and at the same time, the longer the service life of the machine. Reducing the printing pressure (in a broad sense) is an important condition to ensure the smooth operation of the machine. On the premise of ensuring the print quality, the smaller the printing pressure, the better. Reducing the machine speed is another important condition for reducing the machine's rotary inertia. The lower the machine speed is, the smaller its rotary inertia is. Therefore, the machine should not always be in high-speed operation.
The above aspects are only part of the daily maintenance of the printing machine. The quality of the daily maintenance of the printing machine directly affects the service life of the printing machine and the product quality, so it cannot be taken lightly.
