Practice of automatic blow molding machine

Through the practice of automatic blow molding machines for many years, we also feel that imported blow molding machines, especially large blow molding machines, are not perfect, and there are also many problems and defects. Through our study and deepening of the blowing machine, we can find out where the problem lies, and boldly improve some problems and achieve better results.

Despite the complexity of the blow molding machine, it is ever-changing. As long as we take it seriously, we will train high-quality mechatronics maintenance teams. Through more observation, more questions, more thoughts, more practice, accumulated experience, mastering maintenance skills, we will be able to Mainly rely on their own strength, repair, use and manage the blow molding machine. Blowing machine troubleshooting should be practiced more, that is, more practice:

1. To practice more, learn to do it.
For the automatic blow molding machine maintenance personnel, be bold and be brave, do not dare to do it, only speak, do not work, repair the blow molding machine. However, if you want to get familiar with the situation, don't be blind, otherwise it will expand the fault and cause an accident, and the consequences will be unimaginable. At the same time, we must be good at hands-on, first of all to familiarize yourself with the operation panel of the blow molding machine and the contents of each menu, and operate freely. At the same time, we must make full use of the self-diagnosis technology of the blow molding machine to quickly solve the problem. Now the more the bottle blowing machine develops, the self-diagnosis ability is getting stronger and stronger.

2. Practice more, develop hands-on skills and practical skills
Sometimes some blower malfunctions seem ambiguous, and it is unclear whether it is an electrical fault or a mechanical fault. We have adopted a "separation method" to completely separate the control of the electrical part from the original circuit. There are many other methods, such as "isolation method". "Replacement method", "contrast method", "knocking method" and other methods can be used as an effective means to help us find and troubleshoot.

3. To practice more, learn to use related instruments
Such as oscilloscope, multimeter, online circuit tester, short circuit checker, computer, programmer, etc. can help us to judge and check the specific circuit, especially PLC programmer, computer, to be skilled to use, free input and output blower parameters , online testing about state, system initialization, etc. This is very helpful for analyzing faults, especially complex faults, and solving problems.

4. To practice more, carry out "reform"
Often in the normal work, a certain component damage (such as selection switches, buttons, relays, etc.) and no spare parts, try to repair or use temporary special methods to make the blow molding machine work normally. Go on and wait until the spare parts come in and recover.

5. To practice more, you have to repair the board yourself.
Generally speaking, the circuit board of the blow molding machine has good reliability and the failure rate is extremely low. Generally, when checking the blow molding machine, do not doubt the problem of the board first. It can be eliminated by repeated methods such as removal, initialization, and hot and cold start PLC. If it does prove to be a board problem, fix it. These boards (generally no drawings) are expensive, so the quality of the blower board is extremely important. Once the board is damaged and there are no spare parts, it will not be repaired at the moment, which will inevitably stop the machine, which will seriously affect production. Sometimes the circuit board is only a very small fault. As long as it is carefully checked, it is not difficult to find the problem. We have repeatedly found faults such as individual capacitor leakage, board soldering, short circuit, etc. Some circuit board faults are more complicated, but as long as the time is passed, Check with the instrument, it can still be repaired; but there are some boards that are in serious condition, especially large-scale integrated circuits. It is difficult to maintain, and the original device has no spare parts. It can only buy the board or send it out for repair. It is very beneficial to repair the board by yourself. On the one hand, it can save costs for the enterprise and solve the urgent need. On the other hand, it can be very useful to "dissect the sparrow" to familiarize itself with the electronic circuit and cultivate its own analytical judgment and hands-on ability.
