1. Static maintenance of printing machine
The static maintenance of the printing machine refers to the maintenance of the machine in the static state.
1. Establish rules and regulations for machine maintenance. The maintenance of the offset press should be based on the instruction manual of the machine. Such as regular oil changes, filter cleaning, and regular inspection of machine accuracy.
2. Strengthen the maintenance of important parts. Gears, cams, sprockets, rollers and bearings are the most important parts on the printing press, and their maintenance is different from other parts, because changes in their accuracy will affect the final printing quality. The spring is the most used part of the machine for the force balance mechanism. The quality of their work directly determines the precision of the coordination of the moving parts. The spring must have sensitive elasticity, and the hysteresis elasticity and irrecoverable plastic deformation are the work of the spring. Extremely unfavorable. If the above problem is found, the spring needs to be replaced immediately.
3. Carry out technical reforms and strengthen machine maintenance. Machine maintenance requires that the machine be designed with the convenience of machine maintenance in mind. However, due to the complexity of the printing press, it is obviously impossible to consider each factor, and the content of machine maintenance will also change due to environmental changes. Therefore, it is necessary to improve the structure that is not conducive to machine maintenance without affecting the normal work.
Second, the dynamic maintenance of the printing press
The dynamic maintenance of the printing machine refers to the maintenance of the machine under the dynamic state of the printing machine. The static maintenance of the machine is the premise of 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. The main contents that should be maintained under the dynamic state of the machine are analyzed from the following aspects.
1. Machine preparation status detection. The ready state of the machine can be checked by jogging or turning. Other items such as tools are stuck in the machine; whether the installation position of the printing plate is appropriate, if it is not suitable, it may damage the printing plate or cause great difficulty in finding rules; whether the installation of the blanket is suitable, if it is not suitable, it may be It may cause printing failure. In severe cases, the blanket or machine may be damaged.
2. The lubrication state of the machine. First of all, you can observe whether the oil path of the machine is unobstructed through the oil mark. If there is no oil in the oil mark or the observation is not clear at the oil mark, you should stop the engine and check the oil path carefully for oil leakage. Although the leakage of the machine is easy to observe, it is difficult to find the cause. For machines such as sliding bearings, low speed is not conducive to lubrication, especially jog or low-speed operation has a greater impact on its lubrication. Therefore, before carrying out such operations, it is best to lubricate the idling machine first, which is also a primary task that should be done before going to work every day. The oil pump of some machines is driven by the host, so when the point is reversed, not only can the oil circuit not be refueled, but the oil in the oil circuit will be sucked back to the tank. This is very dangerous, so the reverse point should be avoided. Lubrication of some more important parts can also be detected by the temperature of the metal near it. If the temperature is too high, it indicates that there is a problem with the lubrication.
3. Impact during the operation of the machine. At the same time, the service life of the machine can also be extended. Reduce the printing pressure. The smaller the impact during the operation of the machine, the better the printing. (Pressure in the broad sense) is an important condition to ensure the smooth operation of the machine. Under the premise of ensuring the quality of the printing, the smaller the printing pressure, the better. Reducing the speed of the machine is another important condition for reducing the rotational inertia of the machine. The lower the speed of the machine, the smaller the inertia of the machine. Therefore, the machine should not be kept at high speed all the time.
The above aspects are only part of the daily maintenance and maintenance of the printing press. The quality of the 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.
Square Two-part Lifting Column
The square Lifting Column is a kind of equipment used to control the intelligent lifting table, which is usually composed of a column, a motor, a control system and a power supply. According to different usage scenarios and functional requirements, lifting columns can be divided into the following categories:
