Meltblown Nonwoven Production Line Structure Principle and Precautions

Meltblown Nonwoven Fabric is different from the traditional spunbond production. It uses high speed hot airflow to stretch the polymer trickling out of the spinnerets, turning it into a kind of ultra-fine short fiber, which is guided to the rollers for cooling and relying on its own viscous force to form.

Meltblown Nonwoven Production Line

Its production process is a flowing process, from the loading and unloading of polymer materials, to the melting and extrusion of materials, through the metering pump metering, the use of special spinneret module to spray, high-speed hot airflow to the spinneret out of the polymer trickle reasonable stretching guide, cooling to the roller molding, to the lower end of the material receiving processing, are all in one go, any one link problems, may cause production interruptions, to find problems in a timely manner, timely solution to deal with problems.

Meltblown Nonwoven Production Line, including many single equipment, such as feeding polymer loading machine, screw extruder, metering pump device, spinneret module, heating system, air compressor and cooling system, receiving and winding device. These devices work individually and are commanded jointly by plc and industrial control computers, etc., forming a synchronization and tension control system, useful for inverter control of extrusion and drive, winding, etc., and temperature control systems to control heating, inverter will also control fans and cooling, etc. At present, the domestic spinneret module can not do very high precision, need to import from abroad, and other accessories, the current domestic production has been able to maintain the efficiency will be relatively high.

Some mechanical problems, easy to find and solve, such as a bad drive roller bearings, will make a strange noise, but also easy to find the right parts to replace. Or screw reducer is bad, will obviously cause speed fluctuations while making a lot of noise.

But electrical problems, if there is a failure, relatively hidden, such as a bad contact of the PLC, will cause the linkage is not normal. A certain drive optocoupler of the inverter is not normal, causing the motor three-phase current fluctuation is very strong or even phase failure stop. The parameters on the winding tension are not matched well, which will cause the winding untidy. Or a certain line leakage, causing the whole production line to trip and can not start.

Frequency converter and tension control system, because in this type of equipment, the use of relatively large power, if the site does not pay attention to cold cutting and dust removal, but also easy in the production process, because of high temperature and static electricity and downtime.
