Description

Multi-die spinneret structure of melt-blown fabric

Technical Field

The utility model relates to a textile manufacturing field, concretely relates to melt-blown fabric's multimode head spouts a structure.

Background

The prior melt-blown fabric production adopts a single-die single-row-hole spinneret plate, the flexibility of the spun fiber web is difficult to control and can only be controlled by hot air temperature, and the spinneret plate has a single-row-hole structure, so that when individual holes are damaged, the product quality can be directly influenced; meanwhile, the single-die spinneret plate is single in used raw material, the most used raw material at present is polypropylene, and the product has low strength and wear resistance although being soft in hand feeling, so that the application of the product to multiple fields is severely limited.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the production of melt-blown fabric all adopts single-mode head list hole spinneret, and production quality is not good, and output is low, and aim at provides a multi-mode head of melt-blown fabric spouts a structure, through adopting a plurality of modes that have single-row spinneret hole or the mode that the multi-row spinneret hole spouts the melt die head combination, can use different performance's raw materials at different die heads, can produce the product that possesses multiple performance, great promotion product quality and output.

The utility model discloses a following technical scheme realizes:

the multi-die spinneret structure of the melt-blown fabric comprises a plurality of melt-blown die heads arranged above a net forming curtain, and is characterized in that the melt-blown die heads are arranged in a plurality and are sequentially arranged along the moving direction of the net forming curtain, and the plurality of melt-blown die heads comprise single-row hole die heads and multi-row hole die heads.

The utility model discloses a spout the silk structure, through adopting a plurality of modes that have the single-row spinneret orifice or the mode that spout the combination of melting die head of multirow spinneret orifice, can use different performance's raw materials at different die heads, can produce the product that possesses multiple performance, great promotion product quality and output. The utility model adopts a plurality of die heads to work simultaneously, and the output can be greatly improved; and the damage of a single spinneret orifice does not influence the product quality any more, the production can be realized without stopping the machine all the year round, if one spinneret plate is seriously blocked, when the spinneret plate needs to be replaced and cleaned, the corresponding process parameters of the die head only need to be directly turned off, then the net forming speed of the other die head is reduced, the product quality is not influenced, the yield loss caused by the shutdown and the spinneret plate replacement is reduced, and the production efficiency is greatly improved.

The three spray-melting die heads are arranged, the spray-melting die head positioned in the middle is a single-row hole die head, and the spray-melting die heads on the two sides are multi-row hole die heads.

The utility model discloses different die heads can use the raw materials of different performance, for example, melt in the middle of melt the die head and can use the polymer raw materials that has high filtration effect, acid and alkali-resistance, the die head of both sides can use the polymer raw materials that has brute force, resistant chemical corrosion, the product performance that three die head combined work gained like this can be good, can directly be used for the filtering material in fields such as health, chemical industry.

The spinneret plate of the die head with the single row of holes is rectangular, the spinneret plate of the die head with the multiple rows of holes is triangular or circular, and the arrangement of the spinneret holes on the spinneret plates with different shapes is different, so that different fiber shape combinations can be formed, and the fiber performance can be changed.

The number and the precision of spinneret orifices on different spray-melting die heads are different, so that the process requirements of different products can be met, and the product types are expanded.

The distance between the spray melting die head and the web forming curtain is 10-30cm, so that the fibers sprayed by the plurality of die heads can be better overlapped.

The utility model discloses concrete quantity, precision and the arrangement of spinneret orifice can be selected according to the actual demand on the well spinneret.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the utility model relates to a melt-blown fabric's multimode head spouts a structure, through adopting a plurality of mode that have the combination of the mould head of spouting of single row of spinneret orifice or multirow spinneret orifice, can use the raw materials of different performance at different mould heads, can produce the product that possesses multiple performance, great promotion product quality and output;

2. the utility model relates to a multi-die spinneret structure of melt-blown fabric, when needing to change the spinneret, only need directly turn off the technological parameter that this die head corresponds, then reduce the net-forming speed of another die head can, can not influence product quality, reduced and shut down the output loss that changes the spinneret and bring, improve production efficiency greatly;

3. the utility model relates to a melt-blown fabric's multimode head spouts a structure, the range of spinneret orifice is different on the spinneret of different shapes to can form different fibrous shape combinations, can be used for changing the fibre performance.
