In which fields can polypropylene spinning machines be used?

It can be used in the field of recycled materials

2. High-frequency hot roller heating can be adopted, which features 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 operates stably, has a low failure rate, and is simple and convenient to operate and maintain

The function of the polypropylene spinning machine is to make the molten melt enter each spinning box through the bend, be sprayed out by the spinning head by the metering pump, be cooled and solidified into filaments, and then continue to cool through the channel before being wound into shape. The polypropylene spinning machine is mainly composed of several parts, including the spinning control system, the biphenyl boiler control system, and the winding machine control system.

The spinning control system of the polypropylene spinning machine mainly includes the transmission control of the metering pump, the transmission control of the oil agent pump, and the collection and recording of some on-site temperature and pressure signals. Each spinning position on site is equipped with a button box. The start and stop of the metering pump and the oil agent pump are controlled by the on-site buttons, 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 in control between metering pumps and oil agent pumps lies in that metering pumps are usually driven by a frequency converter one-to-one, while oil agent pumps are driven by a frequency converter one-to-multiple.

Since its establishment in 2002, Jiangxi Donghua Machinery Co., Ltd. has been engaged in the research and development, production and sales of complete sets of equipment for chemical fibers.
