Description
Technical Field
The utility model relates to an air current deflector for a melt-blown method loom spinneret.
Background
The melt-blown gas filter material is formed by randomly distributing and sticking polypropylene superfine fibers together, has white, flat and soft appearance, the fineness of the material fibers is 0.5-1.0 mu m, and the random distribution of the fibers provides more heat bonding opportunities among the fibers, so that the melt-blown gas filter material has larger specific surface area and higher porosity (more than or equal to 75 percent); after the high-pressure electret filtering efficiency, the product has the characteristics of low resistance, high efficiency, high dust capacity and the like.
The melt-blown fabric is formed by drafting polymer melt trickle extruded from a spinneret orifice by adopting high-speed hot air flow; products sold in the market at present enter an air cavity after being divided by a small hole, and a jet flow channel is a narrow gap to give out air, so that the design of the flow guide tooth of the utility model is not available; the uneven distribution of the airflow can cause the uneven distribution of the fiber of the melt-blown fabric in the direction of a nozzle, and the grade of the finished product of the fabric is limited, so that the superfine fiber is formed and collected on a coagulation net curtain or a roller, and is bonded to form the melt-blown non-woven fabric; the quality of the spin pack directly determines the performance of the melt blown nonwoven.
Disclosure of Invention
In order to solve the problem, the utility model aims at providing a melt and spout for weaving machine spinneret air current deflector makes the air jet more steady to the size is even more steady to the pulling of fuse fiber, promotes to melt and spouts the quality of unwoven cloth.
The purpose of the utility model is realized through the following technical scheme:
an air flow deflector for a spinneret nozzle of a melt-blown loom comprises a melt fluid feeding plate 1 and a spinneret plate main body 2; the bottom of the spinneret plate main body 2 is connected with a melt fluid feeding plate 1, and a melt flow channel 11 is arranged on the upper surface of the melt fluid feeding plate 1; the melt runner 11 is communicated with the inner cavity of the spinneret plate main body to form a melt runner 4; the method is characterized in that: two sides of the upper bulge of the spinneret plate main body 2 are provided with symmetrical gas jet plates 3; the upper surface of the spinneret plate main body 2 is provided with an air cavity 21, and the top end of the bulge is provided with a row of uniformly distributed spinneret orifices 22; the gas jet plate 3 is provided with a gas inlet 31 and a diversion trench 32, the gas inlet 31 is communicated with the gas cavity 21 and forms a diversion flow 5 through the diversion trench, and a symmetrical high-speed gas flow with a certain included angle with the spinneret orifice 22 is formed.
The diversion trench 32 is in the shape of a straight trench, a straight trench with an arc, a triangle, a trapezoid, a circle or a rectangle.
The air flow deflector for the spinneret nozzle of the melt-blown loom is characterized in that: the airflow guide plate is made of metal materials.
The airflow guide plate is made of a non-metal material.
The technical effects of the utility model reside in that: the gas jet plate is provided with the guide grooves in various shapes, and the introduction of the guide grooves enhances the stability of gas jet flow, so that the spinning process becomes more uniform and stable.

Detailed Description
As shown in fig. 1-5, the present invention comprises a melt fluid feed plate, a spinneret plate body, and a gas jet plate; the molten chemical fiber raw material enters a melt flow channel of a spinneret plate main body from a hot runner of a molten fluid feeding plate and flows out in a filamentous form from a spinneret orifice of the spinneret plate main body; high-temperature and high-pressure gas enters a gas cavity formed by the spinneret plate main body and the gas jet plate from a gas inlet of the gas jet plate; then the gas is ejected from the gas cavity to the diversion trench of the gas jet plate by pressurization to form symmetrical high-speed gas flow with a certain included angle with the spinneret orifice of the spinneret plate main body, thereby drawing the chemical fiber melt ejected from the spinneret orifice of the spinneret plate main body to form micro fibers.
The further design is that: the airflow guide plate is made of SUS431, SUS630, SUS440C, S136H, P20 or 4CR 13.
The further design is that: the airflow guide plate is made of polyimide composite materials, zirconia ceramics or silicon nitride ceramics.
The utility model is characterized in that: the gas jet plate is provided with guide grooves in various shapes, and the introduction of the guide grooves enhances the stability of gas jet flow, so that the spinning process becomes more uniform and stable.
