Components of meltblown non-woven fabric machine

Meltblown non-woven fabric machine is relatively large-scale equipment, and its operation is more complicated. It can produce high-quality melt blown cloth because of the operation and coordination of the various components of the melt blown non-woven fabric machine. The following is a specific introduction to the components of the meltblown non-woven fabric machine.

The basic part of the meltblown non-woven machine

Key equipment such as melt blown head, automatic charging system equipment components, ultrasonic cleaning machine, air heater, centrifugal fan, screw extruder, melt blown web forming machine, melt blown offline winding machine, melt blown offline slitting machine.

The core component of the meltblown non-woven machine

Spinneret

The spinneret for melt spinning is a representative spinneret for the manufacture of synthetic fibers such as polyester and nylon. The thermoplastic resin is heated and melted, extruded through the spinneret in air or water at a certain speed, and cooled. Spinning method of coagulation into fibers.

The core technology is the small nozzle on the spinneret. This nozzle is not only small in size but also has a complicated hole pattern on such a small nozzle, which is extremely difficult to process. The nozzle processing process takes several months. If the processing accuracy is not high, the final meltblown cloth produced will not meet the corresponding technical requirements, which will affect the protective performance of the mask.

The structure of the spinneret is divided into three forms: round, fan-shaped, and rectangular according to the shape of the spinneret. At present, circular plates and rectangular plates are more commonly used. In order to be suitable for different kinds of chemical fiber spinning occasions, circular spinnerets are divided into flat plate type, flange plate type, flat plate ring, flange ring, and so on. Rectangular spinnerets are further divided into rectangular flanges and rectangular grooves, etc., which are mostly used for short fiber spinning with a large number of holes.

Meltblown die head

The die head includes a die head body, a spinneret, and an air plate. The spinneret and the gas plate are detachably installed in the main body of the die, a spinneret hole is arranged in the spinneret, and a number of gap grooves are arranged between the spinneret and the gas plate. A number of gas circulation channels are also opened in the main body of the die head, and the gas circulation channels are communicated with the slit grooves. An air pipe connecting end is arranged on the outer wall of the die main body, and the air pipe connecting end is communicated with the gas collecting cavity through a gas pipe. One end surface of the spinneret hole of the spinneret is fixedly connected with an interval flow stabilizing member, the other end surface of the spinneret hole is fixedly connected with a pipe connection device, and the spinneret hole is connected with the discharge port of the screw extruder through the pipe connection device.

In the melt-blown non-woven machine, the melt-blown die is one of the core components to realize the drawing and molding of the polymer. Its design and accuracy directly affect the length, uniformity, toughness, fineness, and many other aspects of the wire drawing, thereby having a decisive impact on the quality of the final coil.

Melt blown air heater

That is the pipeline heater, which consists of two parts: the body and the control system. The heating element is made of stainless steel pipe as a protective sleeve, high-temperature resistance alloy wire, crystalline magnesium oxide powder, formed by a compression process. The control part adopts advanced digital circuits, integrated circuit triggers, high back-pressure silicon controlled rectifiers, etc., with adjustable temperature measurement and constant temperature systems to ensure the normal operation of the electric heater.
