the eight devices of the meltblown non-woven fabric machine.

Melt-blown non-woven fabric machine is large-scale equipment for producing melt-blown non-woven fabrics. Its composition and structure are relatively complicated and consist of many devices. These devices have their own irreplaceable functions, and they can produce high-quality meltblown non-woven fabric products in cooperation with each other. The following are the eight devices of the meltblown non-woven fabric machine.

The equipment of the meltblown nonwoven production line is about 6m high, about 5m wide, and about 20m long. The production equipment is as follows:

Screw extruder

\The diameter of the screw is generally 100~120mm, and the length/diameter ratio is 30. Its purpose is to melt the slices.

Metering pump

Its function is to accurately measure, control the output and the fineness of the fiber, as a gear pump, continuously transport the melt to the spinneret.

Melt filter

Its function is to filter out the impurities in the melt to avoid clogging the spinneret holes.

Conveying net curtain

The melt-blown fiber is evenly received and spread on the net and transported forward. There is a suction fan under it to discharge the hot air coming down from the top.

Spinning box

This is the key equipment of the melt-blown process. There is a strip-shaped spinneret with a long row of spinneret holes, generally about 1500 nozzle holes per m length. The two sides of the spinneret are equipped with hot air nozzles, and there are hot air nozzles underneath, which form a 50bangle with the nozzle holes. After the fiber is ejected, the high-speed hot air is used to stretch the airflow immediately to blow the fiber off and become a superfine fiber.

Hot air blower and heater

Provides the temperature and pressure of the hot air used in the spinning air stretching process. It is heated by electricity and consumes a lot of power.

Feeding system

It is composed of 3 measuring hoppers, which are used to measure white slices, masterbatch, and additives. These three components enter the mixing and agitator below to mix evenly, and then put into production.

The coiling machine adopts fully automatic coiling

Pack the meltblown cloth in rolls. Meltblown nonwovens are characterized by ultra-fine fibers, and the smallest fiber diameter can be achieved, generally between 1 and 5Lm. The finer the fiber, the better the quality of the meltblown cloth, but the output is relatively reduced. Because the fiber is superfine, its specific surface area is large, and the adsorption capacity is strong, which is the most prominent advantage of melt blown cloth.

If we understand the specific functions of these devices when the meltblown non-woven fabric machine fails, we can more accurately find the fault location, and then repair it in time.
