The function of the polypropylene spinning machine is to make the melted melt enter each spinning box through the bend, and be ejected from the spinning head by the metering pump, and be condensed to solidify into a thread, and continue to be cooled through the tunnel and finally wound into a shape. The polypropylene spinning machine is mainly composed of spinning control system, biphenyl boiler control system, winder control system and so on.

The spinning control system of polypropylene spinning machine mainly includes metering pump transmission control, oil pump transmission control, and some on-site temperature and pressure signal acquisition records. Each spinning position in the field is equipped with a button box, and the start and stop of the metering pump and the oil pump are controlled by the on-site button, so the enable signal of the frequency conversion is generally given by the terminal.

Since both the metering pump and the oil pump are synchronous motors, the frequency conversion only requires general open-loop control. The difference between the control of the metering pump and the oil pump is that the metering pump is usually driven by a frequency converter, while the oil pump is driven by a frequency converter.

Main features of polypropylene spinning machine:

1. Can be used in the field of recycled materials

2. It can be heated by high-frequency hot roller, with low energy consumption and uniform temperature of the hot roller

3. The side blowing wind speed is uniform and stable

4. The polypropylene spinning machine runs stably, has a low failure rate, and is simple and convenient to operate and maintain
