Structural Principle of Producing Meltblown Non-woven Fabric Line

Meltblown non-woven fabrics are different from traditional spunbond production. It uses high-speed hot air to stretch the polymer trickle from the spinneret hole of the module, and turns it into an ultra-fine short fiber. , guide it to the roller to cool, and rely on its own adhesive force to form.

1. The production process of meltblown non-woven fabrics

It is a flow process, from the loading and unloading of polymer materials, to the melting and extrusion of materials, after the metering of the metering pump, the melt blown cloth is sprayed using a special spinneret hole module, and the high-speed hot air blows the material. The trickle of the polymer coming out of the spinneret hole is reasonably stretched and guided. After cooling, it is formed on the roller, and the material is received and processed at the lower end in one go. Problems in any link may cause production interruption. Problems must be found in time. Solve problems in a timely manner.

2. Structure of meltblown non-woven fabric

Meltblown non-woven production line in melt blown non-woven fabric factory, including many single equipment, such as feeding polymer feeder, screw extruder, metering pump device, spinneret module, heating system, air compressor and cooling system, receiving and winding device.

These meltblown fabric work alone and are jointly commanded by plc and industrial computer to form a synchronization and tension control system, which is useful for frequency converters to control extrusion and transmission, winding, etc., as well as temperature control systems to control heating , the frequency converter will also control the fan and cooling.

Some mechanical problems are easy to find and solve. For example, if a certain drive roller bearing is broken, it will make abnormal noises. It is also easy to find suitable accessories to replace. Or the reducer of the screw is broken, which will obviously cause speed fluctuations and make a loud noise.
