Description

Structure of Nonwoven Composite Ceramic Spinneret

technical field

The invention relates to a structure of a non-woven fabric composite ceramic spinneret, and belongs to the technical field of textiles.

Background technique

In the prior art, non-woven fabric spinnerets are made of different materials according to the characteristics of different polymers and different spinning processes, but stainless steel materials of different grades are commonly used. The prior art is to rework the required spinneret holes and feed troughs on a single piece of spinneret, which is integral.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a structure of a non-woven fabric composite ceramic spinneret.

In order to achieve the above object, the technical scheme adopted in the present invention is:

The structure of the non-woven fabric composite ceramic spinneret includes a spinneret main body, on which the die tip is inlaid with a ceramic insert, and the ceramic insert is provided with a material guide groove and a spinneret channel. Ceramic inserts can be a single unitary piece or a combination of multiples.

As a further arrangement of the above solution, the spinneret channel is a circular spinneret channel or a special-shaped spinneret channel.

The guide chute can be any one of T-shaped, oblique cone or upper part with short cone. Of course, the guide trough can also be made into other geometric shapes.

The spinneret channel of the ceramic insert is a porous structure.

The ceramic inserts are alumina inserts (ceramic inserts made of alumina), zirconia inserts (ceramic inserts made of zirconia), silicon nitride inserts ( Select any one of the ceramic inserts made of silicon nitride. Of course, the insert can also be made of other structurally hard materials.

The spinneret body is made of stainless steel spinneret body, or aluminum alloy, or other materials.

The ceramic insert is fixed to the main body of the spinneret by using high temperature resistant glue, or the ceramic insert is fixed to the main body of the spinneret by using an interference fitting structure. Of course, the ceramic insert can also be fixed to the spinneret body in other ways.

The ceramic insert may be one-piece through length or may be segmented.

The structure of the non-woven fabric composite ceramic spinneret of the present invention is used in a non-woven fabric machine. The ceramic inserts with prefabricated required spinneret channels and material guide grooves are fixed on the spinneret main body to make a composite sprayer. silk board.

Compared with the prior art, in the present invention, the thread paths on the traditional spinneret (consisting of the spinneret holes and the material guide trough) must be made together in a concentrated manner, which is very difficult to manufacture, and if part of the thread paths are out of tolerance (out of tolerance range) ), it will directly cause the entire spinneret to be out of tolerance (out of tolerance range). The advantage of the invention is that the multiple threads on the whole spinneret are dispersed and manufactured, the qualified ceramic inserts are installed, and the unqualified ceramic inserts are eliminated, so as to ensure the quality of the whole spinneret. That is, the combined structure of the present invention is to install the ceramic inserts that have prefabricated the required material guide grooves and spinneret holes on the spinneret main body, so that the whole block spray can be effectively avoided due to the out-of-tolerance part of the spinneret. The phenomenon that the silk board is out of tolerance.

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Fig. 2 is the front view structure schematic diagram of Fig. 1;

FIG. 3 is an enlarged structural schematic diagram of a ceramic insert.

Detailed ways

As shown in Figure 1, Figure 2, Figure 3, the structure of the non-woven fabric composite ceramic spinneret of the present invention includes a filter screen 1, an upper cover 2, a spinneret body 3, and the spinneret body 3 is embedded with The ceramic insert 5 and the seal 4 are provided with a material guide groove 5-1 and a spinneret channel 5-2 on the ceramic insert 5.

In a specific production process, the ceramic inserts 5 on the spinneret main body 3 can be single or multiple according to customer requirements.

The spinneret tunnel 5-2 in the present invention is a circular spinneret tunnel or a special-shaped spinneret tunnel.

In the present invention, the shape of the material guide trough 5-1 can be any one of T-shaped, oblique cone, or a short cone at the top. In this embodiment, the shape of the material guide trough 5-1 is a T-shape.

In the present invention, the ceramic insert 5 is of an integral structure or a segmented combined structure, that is, the number of threads on the ceramic insert 5 may be one or a combination of multiple ones.

In the present invention, the ceramic inserts 5 are alumina inserts (ceramic inserts 5 made of alumina), zirconia inserts (ceramic inserts 5 made of zirconia), nitrogen Any of the silicon carbide inserts (ceramic inserts 5 made of silicon nitride), or other structural hard materials.

In the present invention, the spinneret body 3 is a stainless steel spinneret body. That is, the spinneret body 3 is preferably made of stainless steel. Of course, the spinneret body 3 can also be made of other materials, such as aluminum alloy.

In the present invention, the ceramic insert 5 is fixed to the spinneret main body 3 by using high temperature resistant glue, or the ceramic insert 5 is fixed to the spinneret main body 3 by an interference fitting structure. Of course, the ceramic insert 5 can also be fixed to the spinneret body 3 in other ways.

The production process of the present invention is as follows:

Fabrication of the spinneret body 3 and the fabrication of the ceramic insert 5, and then the spinneret body 3 and the ceramic insert 5 are fixed into one body, and finally the surface is trimmed.

The above embodiments are only used to illustrate the inventive concept of the present invention, but not to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention by using this concept should fall within the protection scope of the present invention.
