The bottle blowing machine is the crystallization of the integration of machinery, electric control and hydraulic pressure. The electric system is complex, the oil pressure pipelines are crisscross, the controllers are various, and the fault phenomena are various. There are thousands of components in the large-scale bottle blowing machine. If one of the components fails, it will cause the abnormal phenomenon of the bottle blowing machine. There will be problems with the connection of wires and a little negligence. In addition, the large-scale bottle blowing machine has a huge volume and is used without constant temperature bottle blowing workshop. The influence of the environment is easy to cause the failure. Therefore, the problem of "difficult maintenance" of imported bottle blowing machine is in front of us.

How to quickly find out the faults and hidden dangers and eliminate them in time? In my opinion, first of all, we should have a high sense of responsibility; second, we should strive to master the numerical control hydraulic technology. After years of practice in maintaining the bottle blowing machine, we should see, ask, remember, think and practice more, and gradually improve our technical level and maintenance ability, so as to adapt to various complex situations, solve difficult problems and repair the bottle blowing machine well.

1. Read more about electronic circuit of bottle blowing machine

To see more, we need to understand the characteristics and functions of various electronic circuit systems of bottle blowing machines and PC and PLC programmable controllers; to understand the alarm and elimination methods of electronic circuit systems of bottle blowing machines; to understand the meaning of parameter setting of PC and PLC bottle blowing machines; to understand the programming languages of PC and PLC; to understand the action programming methods of bottle blowing machines; to understand the operation and menus of control panel of bottle blowing machines What do you think of the contents of the book? In my opinion, we should focus on the key points and make clear the context. The key point is to understand the basic composition and structure of the controller of the bottle blowing machine and master the block diagram. The rest can be "toured" and read through, but each part of the content should be focused on understanding and mastering. Because the internal circuit diagram of the controller of the bottle blowing machine is quite complex, which is not provided by the manufacturer. Therefore, it is not necessary to make it clear in detail. To focus on understanding the role of each part, the function of each board, the direction of the interface, the meaning of LED lights and so on. Now the controller of bottle blowing machine has many models and is updated quickly. Different manufacturers and models often have great differences. It is necessary to understand its generality and individuality.

2. Read the electric diagram of bottle blowing machine and digest the electric diagram of bottle blowing machine

For each electrical component, such as contactor, relay, time relay, etc., as well as the input and output of PC and PLC, it should be indicated one by one on the electrical diagram.

3. Read more hydraulic diagram of bottle blowing machine and digest it deeply

For the mechanical and hydraulic diagram of bottle blowing machine, we should make clear its function and context. And one by one on the drawing to indicate, such as clamping by which solenoid valve action? What are the corresponding PC and PLC outputs and inputs? Write clearly in the figure, so that from electrical to mechanical action to the end, at the same time, we should focus on understanding the parts closely related to machine and electricity. Now the bottle blowing machine adopts electro-hydraulic proportional technology, we should focus on understanding its function and function, especially its adjustment method and adjustment data, static and dynamic proportional valve current and corresponding pump pressure, understand both electricity and machine, mechatronics In this way, the ability to solve problems will be great.
