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 printing plate is installed in the appropriate position, if it is not suitable, it may damage the printing plate or bring great difficulty to find the rules, whether the rubber blanket is installed, if it is not suitable, it may cause printing failure, and in serious cases, it may cause damage to the machine.
2. The lubrication state of the machine. First of all, you can observe whether the oil circuit of the machine is smooth through the oil mark, if the oil mark is not oil or the oil mark is not clear, you should stop the emergency and carefully check whether there is oil leakage in the oil circuit. Oil leaks from machines are easy to observe, but it can be difficult to find the cause. For machines such as plain bearings, low speed is not conducive to its lubrication, especially jog or low speed operation has a greater impact on its lubrication. Therefore, before carrying out such operations, it is best to refuel and lubricate the idling machine, which is also a top priority to do before going to work every day. The oil pump of some machines is driven by the main engine, so when the reverse point is reversed, the oil circuit not only can not be refueled, but will suck the oil of the oil circuit back to the oil tank, which is very dangerous, so the reverse point should be avoided. The lubrication of some of the more important parts can also be detected by the temperature of the metal in its vicinity, if the temperature is too high, it indicates that the lubrication is problematic. Common faults and troubleshooting methods of gravure gold and silver ink.
3. Shock during the operation of the machine. The smaller the impact during the operation of the machine, the better it is for printing and at the same time, it can also extend 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, and the smaller the printing pressure is the better under the premise of ensuring the quality of the printed product. 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 in high speed.
