The cotton spinning machine which has the frequency changer

摘要

This invention comes out of the electronic part 9,10 which and is the cotton spinning inside of a plane makes the spot. That is electronic part such as the frequency changer where cooling generates necessary about is many heat. Therefore, that kind of electronic part the suspended matter from the cotton spinning territory, has the cooling fin 16 which extends into exhaust flow 2 where the dust and the other pollutants are absorbed. This exhaust flow 2 is removed the pollutant with filter, 5 keeps being squeezed gradually with that. The cooling effect decreases the quantity and because of that. Vis-a-vis that, in order to prevent overheating of electronic part 9,10, it cannot allow temperature about, disposing the thermometer 17 which sends the signal to control equipment 12 when it has become high, the control equipment, tries to warn the fact that it is the necessity which cleans the filter. As for this presentation, it is possible, at last stage, stops the electric power supply to the electronic part, or makes drive stop to do gradually.
