Tips for troubleshooting of bottle blowing machine equipment

Blow molding machine equipment is the crystallization of the integration of machinery, electric control and hydraulic pressure. The electric is complicated, the hydraulic pipelines are crossed, the controllers are various, and the failures are also strange and different. There are thousands of components in the large-scale blow molding machine. If one of the components is faulty, it will cause abnormalities in the blow molding machine, and there will be problems with the connection of the wires and a little negligence. Large-scale blow molding machines are bulky and are used under conditions of no constant temperature blow molding workshop. The impact of the environment can easily cause failures. For this reason, the problem of "difficult maintenance" of imported bottle blowing machines is placed in front of us.

How to quickly find out the faults and hidden dangers and eliminate them in time? I think we must first have a high sense of responsibility; second, we must work hard to master the CNC hydraulic technology, and the practice of maintaining the blow molding machine for many years believes that we should look more, ask more, remember, think, and practice more, and gradually improve our technical level. Only with the maintenance ability can we adapt to various more complicated situations, solve difficult problems, and repair the bottle blowing machine.

1. To see more information about the electronic circuit of the bottle blowing machine

To read more, to understand the characteristics and functions of various blow molding machine electronic circuit systems and PC, PLC programmable controllers; to understand the alarm and troubleshooting methods of the blow molding machine electronic circuit system; to understand PC, PLC blow molding machines The meaning of parameter settings; to understand the programming language of PC and PLC; to understand the method of programming the blow molding machine action; to understand the operation of the blow molding machine control panel and the content of each menu, there are often a lot of information, how do you look? I think the main point is to highlight the key points and understand the ins and outs. The key point is to thoroughly understand the basic composition and structure of the bottle blowing machine controller and master the block diagram. The rest can be "visited" and read through, but each part of the content must have a key understanding and mastery. Because the internal circuit diagram of the blow molding machine controller is quite complicated, the manufacturer does not provide it. Therefore, there is no need to clarify in detail. It is important to understand the role of each part, the function of each board, the destination of the interface, the meaning of the LED light, etc. Nowadays, there are many models of blow molding machine controllers, which are updated quickly, and different manufacturers and different models are often very different. To understand its commonality and individuality.

2. Look at the electrical diagram of the bottle blowing machine and the electrical diagram of the digesting bottle blowing machine

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

3. Look at the hydraulic diagram of the bottle blowing machine and digest it in depth

For the mechanical and hydraulic diagrams of the bottle blowing machine, it is necessary to understand its function and ins and outs. And indicate one by one on the drawing, such as which solenoid valve actuates the clamping? What are the corresponding PC and PLC output and input? It is stated in the picture that this way from electrical to mechanical action, and at the same time, it is necessary to focus on the parts that are closely related to machine and electricity. Now the blow molding machine adopts electro-hydraulic proportional technology, and it is necessary to focus on understanding its role and function. To understand its adjustment method and adjustment data, the proportional valve current and the corresponding pump pressure in static and dynamic conditions, understand both electricity and machine, mechanical and electrical integration, and master a variety of skills, so that the ability to solve problems is great.
