Dynamic Maintenance of Gravure Printing Presses

Dynamic maintenance of the gravure press refers to the maintenance of the machine under dynamic conditions. 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 check the level of static maintenance of the machine. The dynamic maintenance of the machine is quite important. The following is a summary of the main content of maintenance under machine dynamics from several aspects.
1. Check the condition of the machine before production. How is the machine ready? You can check it by jogging or turning the car. If other items such as tools are stuck in the machine; it is not appropriate to check the position of the plate device. If it is not suitable, it may damage the plate; whether the blanket device is suitable, if it is not suitable, it may cause printing failure. May damage the machine.
2. Lubrication status of relevant parts of gravure printing machine. First of all, it is possible to check whether the oil path of the machine is unblocked by the oil mark. If the oil mark is oil-free or the oil mark is unclear, the production should be stopped urgently. Check whether the oil path is leaking.
Although the machine’s oil spill is simple to see, it is difficult to find the underlying factors. For machines such as sliding bearings, low speed is not conducive to lubrication, especially for jogging or low speed operation. Therefore, before performing such operations, it is best to first idling the machine to refuel, which is also a primary job that should be done before going to the machine every day. Some equipment’s oil pump is driven by the main engine, so when the point is reversed, the oil circuit can not only add fuel, but will suck the oil from the oil circuit back to the fuel tank. This is very dangerous, so the anti-point should be prevented. Lubrication of some of the more important parts can also be checked by the temperature of the adjacent metal. If the temperature is too high, the lubrication is unqualified.
3. Impact during the operation of the gravure printing press. The smaller the impact during machine operation, the better the printing and the longer the life of the machine. Reducing the printing pressure (in a broad sense of pressure) is one of the main conditions for ensuring smooth operation of the machine. Under the condition of ensuring the quality of the printed product, the printing pressure is as small as possible. Reducing the speed of the machine is another major condition for reducing the moment of inertia of the machine. The lower the speed of the machine, the smaller the moment of inertia of the machine, so do not keep the machine at high speed.
