How to the perfect Chinese blow molding machine

Through years of full automatic extrusion blow molding machine practice, we also feel that imported blow molding machine, especially large-scale blow molding machine is not perfect, there are also many problems and defects. Through our study and deepening of blow etrusion moulding machine, we find out the problems, boldly improve some problems, and achieved good results.
Despite the complex and ever-changing faults of Chinese extrusion blow moulding machine, as long as we take them seriously and cultivate a high-quality maintenance team of mechatronics, we will be able to rely mainly on our own strength to repair, use and manage the blow moulding machines by looking more, asking more, thinking more, practicing more, accumulating experience, mastering maintenance skills and integrating them. OK. Blow molding machine troubleshooting should be more practice, that is, more practice:
1., we should practice more and learn to do things.
For the maintenance personnel of automatic blow molding machine, to be bold and careful, to dare to start, will only say, do not start, can not repair the blow molding machine. However, we must be familiar with the situation again, not blindly, otherwise it will expand the fault, causing accidents, the consequences are unthinkable. At the same time, we should also be good at hands-on, first of all, familiar with the blow molding machine operation panel and the contents of the menu, operation freely. At the same time, we should make full use of the self diagnostic technology of blow molding machine to solve the problem quickly. The more developed the extrusion blow molding machine, the stronger the ability of self diagnosis.
2., we should practice more, develop practical skills and practical skills.
Sometimes some blower faults look very blurry, can not distinguish between electrical faults or mechanical faults, we use the "separate method", the electrical part of the control and the original circuit completely separate other methods, such as "isolation method", "replacement method", "comparison method", "knock method" and other methods can be done. As an effective means to help us find and troubleshoot.
3., we should practice more and learn to use related instruments.
For example, oscilloscope, multimeter, on-line circuit tester, short circuit tester, computer, programmer, etc. can help us to judge and check the specific circuit, especially PLC programmer, computer, to be skilled in use, can freely input and output blowing machine parameters, on-line test the relevant state, system initialization, etc. This is helpful for analyzing faults, especially complex faults, and solving problems.
4., we should practice more and carry out "reform".
Often in the normal work of a component damage (such as switch selection, buttons, relays, etc.) and temporarily no spare parts, their own hands as far as possible with gluing method to repair or adopt temporary special methods, so that the blowing machine can work normally until the spare parts to restore.
5., we should practice more. We must do it ourselves. Shui Ko
Generally speaking, the circuit board of blow molding machine has good reliability, and the failure rate is very low. Generally, when checking the blow molding machine, do not suspect the problem of the board first. The method can be eliminated by repeating test, initialization, hot and cold start-up, PLC and so on. If it is proved to be a circuit board problem, it should be repaired. These boards (usually without drawings) are expensive, so the quality of the blow molding machine circuit board is extremely important. Once the circuit board is damaged and no spare parts are repaired, it will inevitably stop, seriously affecting production. Sometimes the circuit board is only a very small fault, as long as carefully checked, it is not difficult to find the problem, we have repeatedly found individual capacitor leakage, virtual welding board, short circuit and other faults, some circuit board faults are more complex, but as long as time, through the use of instrument inspection, or can be repaired; but there are still some circuits The board is in serious condition, especially large-scale integrated circuits, which are difficult to maintain. In addition, the original components have no spare parts, so we can only buy the spare board early or send it out for repair. On the one hand, it can save the cost and solve the urgent problem. On the other hand, it can "dissect the sparrow" familiar with the electronic circuit, and cultivate their own analysis and judgment and hands-on ability is very useful.
