The essence of the standardized operation of the whole machine is a comprehensive reflection of the standardized operation of the six major tracks. The following takes the printing process of a printed matter as an example to talk about the standardized operation of the whole machine.
1. Preparations before starting
Before starting the machine, you should first check the machine, especially when operating the machine that has not been turned on for a long time or the machine of other people. The main inspection place is the joint between the drum and the drum, the gap of the drum, etc. If there is any debris, it should be removed in time. The holy bucket and ink fountain roller are also a key point of inspection. One is to check whether there is debris in the middle. The second is to check whether the ink fountain roller and ink fountain blade are too tight. The ink fountain needs to be opened when the machine is idling. In addition, check whether some important parts (such as delivery teeth, delivery chain, etc.) are loose. In addition, we must not forget the oil standard, especially those devices without oil pressure detection, we should keep this check. Unsafe items such as cardboards, wall plates on both sides of the ink path, cover plates at the receiving area, and foot pedals should be removed in time.
After the above inspection, if the hand truck is used, if the force is uneven within a week, the relevant parts should be checked in detail, and then the machine should be jogged. If there is any abnormality, the machine should be stopped for inspection. After these tasks are done, it can be turned on.
2. Start operation
Before turning on the phone, you should first ring the bell so that people around the machine are ready to pick it up. If there are more people, the ring time should be longer. To ensure safety, you should also observe around. Before pressing the operation switch, the other hand should be placed on the emergency stop switch. If there is an abnormality, the emergency stop should be made (this judgment is usually based on the sound of the machine). Generally, the machine should be idling first when loading the plate, rubber blanket or cleaning the surface of the drum. The purpose is to make the surface of bearings, gears, cams, sprockets and other surfaces have sufficient lubricating oil.
3. The amount of water on, water on, and ink on depends on the specific print. Generally, the amount of water and ink should be slightly larger than the actual needs (by empirical estimation, the required amount can also be given by approximate calculation). When filling the water, be careful not to pour the water out of the water tank or bucket, so as not to drip onto the machine, causing the surface of the machine parts to rust. When applying ink, make the ink as close as possible to the lowest part between the ink fountain blade and the ink fountain roller. It is not appropriate to make the entire ink fountain full. Watering and ink filling should generally be done while parking. If the operation is carried out when the power is turned on, it is necessary to pay attention to safety. In addition, the ink skin and impurities in the ink tank should be removed when applying ink.
Note that the roll paper should be basically the same as the white paper to be printed (format, quantitative, category) until the rules are aligned. If the rules are not accurate, you can make the rules accurate by pulling the plate, borrowing rollers, borrowing rules and other measures.
