Routine maintenance and maintenance of the printing press
The press is one of the highest printing equipment utilization rate for all devices. Ensure the normal operation of the printing press, routine maintenance and repair is essential also very necessary. Here to talk about the following aspects of the machine simple routine maintenance and repair. A static maintenance printer maintenance presses static refers to a static state machine is in the maintenance of the machine. 1. Establish machine maintenance regulations. Offset machine maintenance instructions shall prevail. Such as regular oil changes, cleaning filters, regular testing machine accuracy. 2. Strengthen the maintenance of key components. Gears, cams, sprockets, rollers and bearing the printing of these components are the most important components, the maintenance thereof to be different from other components, as they will affect the accuracy of the final variations. Spring is the largest component force balance mechanism for the machine, which directly determines the quality of the work of moving parts with each other precision level, the spring must be sensitive elastic, elastic and plastic deformation and stagnation unrecoverable work is spring extremely unfavorable. As found above issues need to be replaced immediately spring. Residual solvent printing process hazards 3. technical reform, strengthening machine maintenance. Machine maintenance requirements when designing a machine fully into account machine maintenance convenience. However, due to the complexity of the printing press, to each of these factors are taken into account is obviously impossible, and environmental changes, the contents of machine maintenance will vary. So to those of the structure is not conducive to the maintenance of the machine to be improved without affecting the normal operation of the premise. Second, the dynamic maintenance of the press refers to the dynamic maintenance of the press under the dynamic state of the press in the maintenance of the machine. Static dynamic machine maintenance machine maintenance is the premise of the dynamic operation of the machine at the same time they can turn static detection machine maintenance level. Dynamic maintenance of the machine is very important. Here several ways to analyze the main content of the machine should be maintained under the dynamic. 1. Prepare the machine state detection. How to prepare for the state machine, can jog or jigger to detect. And other items such as tools stuck in the machine; plate mounting position is appropriate, if it is not appropriate to make the printing possible damage or caused great difficulties to find the rules; blanket installation is appropriate, and if inappropriate, it is possible cause print failure, or the machine may cause serious damage. 2. The machine lubrication. First, whether the flow can be observed through the oil standard machine circuit, such as Standard Oil or no oil was observed at the oil standard is unclear, you should carefully check the oil emergency stop if there is leakage. Although the machine is easy to observe the oil spill, but to find the reason it is very difficult. For sliding bearings and the like machines, low speed detrimental to their lubrication, especially jogging or low speeds greater impact on its lubrication. So before making such an operation, it is best to idle machinery lubrication, which is the daily work that should be done before a high priority. Some machines pump is driven by the host, so when the anti point, the oil will not be able to refuel, but will the oil in the oil sucked back into the tank, which is very dangerous and should therefore be avoided anti points. Some of the more important parts of the lubrication can also be detected, such as high temperature, indicating that there is a problem by lubricating the metal temperature in its vicinity. Gravure gold and silver ink and troubleshooting common faults during operation of the machine 3. impact. Impact during operation of the machine smaller and more conducive to printing, but also extend the life of the machine. Reduce printing pressure (pressure in the broad sense) is to ensure the smooth operation of the machine is an important condition to ensure the printing quality in the premise, printing pressure the smaller the better. Reduce the speed of the machine is to reduce the moment of inertia of the machine is another important condition, the lower the speed of the machine, the smaller the moment of inertia, and therefore should not make the machine is always in high-speed operation. Only part of the above aspects of daily care and maintenance of the printing press, the daily care and maintenance level of quality of the printing press, a direct impact on the life and product quality of the printing press, and therefore can not be taken lightly.
