Description

    During the production of masks and melt-blown nonwovens, one of the most indispensable core components is the melt-blown die head. In the melt-blown equipment, the melt-blown die head is one of the core components to realize the wire drawing of the polymer. The design and accuracy directly affect the length, uniformity, toughness, fineness and other aspects of the wire drawing, thus affecting the quality of the final coil. Have a decisive impact.

    The core part of the main machine of the melt-blown production equipment is the spinneret (spinneret), which has many spinneret holes for the melt to pass through. Its production and processing are crucial, which is related to the production efficiency and quality of the melt-blown cloth , Which in turn affects the protective performance of the mask.

1. Micro-hole processing principle of melt-blown cloth spinneret

The machine tool uses the principle of electrical discharge to process high precision, high finish precision micropores. It is used to process precision micro-holes of various types of fuel injection nozzle parts. The range of processing precision circular micro-holes is generally ¢ 0.1 ~ ¢ 0.5mm. The machine tool uses round elongated wire electrodes. The re-feeding mechanism with elongated wire electrode realizes the servo feeding and loss compensation of the electrode during processing. Processing generally uses deionized water working fluid. The machine tool is composed of a host, an electric control box and a working fluid system. The electric control box is composed of an industrial control computer, a special high-frequency pulse power supply for electric spark micro-finishing, a detection servo control unit and machine tool electrical components.

The special machine tool of the spinneret spinneret adopts round and long wire electrode. The re-feeding mechanism with elongated wire electrode realizes the servo feeding and loss compensation of the electrode during processing. Processing generally uses deionized water working fluid.


2.Second, the structure of the melt-blown spinneret

According to the shape of the spinneret, the structure of the spinneret can be divided into three forms: round, sector and rectangle. At present, round and rectangular plates are mostly used at home and abroad. To suit different chemical fiber spinning occasions, the round spinneret is divided into flat type, flange flat type, flat ring, flange ring, etc .: the rectangular spinneret is divided into flange rectangle and flange groove rectangle, etc. , Mostly used for spinning short fibers with many holes.


Meltblown fabric is a non-woven fabric formed by meltblown method, which mainly uses polypropylene as the main raw material. The actual production process of meltblown fabric is more complicated, and the requirements for production equipment are also higher. Its production mainly passes through "melt preparation- "Filtration-metering-melt extrusion from the spinneret hole-melt fine flow drafting and cooling-network" and other six processes. The core component of the main machine of the melt-blown production equipment is the spinneret (spinneret), which has many spinneret holes for the melt to pass through. Its production and processing are crucial, which is related to the production efficiency of melt-blown cloth quality.


At present, the domestic production of melt-blown cloth production equipment has been achieved in China, but the production of core components such as spinnerets still depends on the supply of foreign manufacturers. In extraordinary times, it is very important to be able to provide melt-blown cloth production equipment manufacturers with a spinneret that can meet the needs of high-protection mask melt-blown cloth production.
