Maintenance of Label Printer must be developped during the daily use of the trademark printing machine. The captain implements maintenance and maintenance measures according to the plan. During the maintenance process of the trademark printing machine, the electrical group has more problems. Because the electrical part is printed in the trademark There are many technical components, and it is more prone to problems. For example, the display screen’s control fails, the data cannot be input, or the program appears to be garbled and automatically locks the machine. With the continuous improvement of the manufacturing technology of trademark printing machines, automatic control procedures are becoming more and more. The more. The control system is becoming more and more complex. Therefore, the technical requirements for maintenance personnel are getting higher and higher. Many electrical engineers are learning the technical knowledge of advanced machinery and equipment to meet the market’s demand for human resources. So for electrical maintenance personnel, when repairing these electrified machine problems, some things should be paid attention to.
Before inspecting or repairing new printing equipment, you must be able to understand the electrical schematic diagram and instruction manual of the printing equipment. Because the electrical schematic diagram of a piece of equipment contains all the circuit directions, circuit layouts, and directions of this equipment. And there are marked names and locations of each electrical component. Only by understanding this electrical schematic diagram, the electrical maintenance engineer can quickly and accurately find the location of the problem. So understanding the electrical schematic diagram is some maintenance premise.
Troubleshooting sequence. When a problem is found in the printing equipment. Maintenance personnel should have a basic troubleshooting sequence. The general troubleshooting sequence is to first check whether the power supply voltage is stable, and then test whether the current is normal. Then determine whether the pressure of the air pump is accurate. . Whether the oil system pressure is normal, determine whether the equipment is overloaded, etc. The basic idea is this, but for some experienced maintenance personnel, you can quickly find out the problem based on your own experience. There is no need to follow This investigation method is carried out.
Familiar with the printing servo system. At present, the servo system most used by the state-owned trademark printing presses is the PLC system. The PLC system is used for logical control and protection, and the touch screen is centralized. Therefore, as a repairer, you must It is necessary to understand the maintenance and editing of the PLC system. It is best to be able to complete the system design of a machine and equipment independently. In this way, if there is a system problem, you can quickly find the problem of the program. And can easily solve it.
