Abstract
The utility model provides a side-by-side melt-blown fabric spinneret plate, which comprises a spinneret plate body, wherein the filament outlet surface of the spinneret plate body is provided with a plurality of micropores, and the upper ends of the micropores are connected with two cavities which are mutually separated and symmetrically arranged; the spinneret plate body is further provided with a first feeding hole and a second feeding hole which are respectively communicated with the two cavities. Two polymers with different properties enter the cavity from the first feeding hole and the second feeding hole respectively, and a strand of filaments with different properties is led out from the micropores, so that the melt-blown fabric has more properties and better adsorption effect; the arrangement of the cavity is convenient for the polymer to be distributed more uniformly when entering the micropores.
Description
Technical Field
The utility model relates to a melt-blown fabric production facility technical field specifically is a type melt-blown fabric spinneret side by side.
Background
The melt-blown fabric spinneret plate is an important element in a melt-blown fabric production device, and spinneret holes are formed in the spinneret plate. The spinneret plate is used for changing polymer melt in viscous state into thin flow with specific cross section shape through micropore shape, and solidifying the thin flow through a solidification medium such as air or a solidification bath to form filaments, namely, the filaments enter from the upper end of a spinneret orifice and exit from the lower end of the spinneret orifice. The melt-blown fabric is generally produced by adopting a single polymer, and has single performance and weak adsorption capacity
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: solves the technical problems of single performance and poor adsorption capability of the traditional melt-blown fabric produced by adopting a single polymer.
The utility model provides a side-by-side melt-blown fabric spinneret plate, which comprises a spinneret plate body, wherein the filament outlet surface of the spinneret plate body is provided with a plurality of micropores, and the upper ends of the micropores are connected with two cavities which are mutually separated and symmetrically arranged;
the spinneret plate body is further provided with a first feeding hole and a second feeding hole which are respectively communicated with the two cavities.
Two polymers with different properties enter the cavity from the first feeding hole and the second feeding hole respectively, and a strand of filaments with different properties is led out from the micropores, so that the melt-blown fabric has more properties and better adsorption effect; the arrangement of the cavity is convenient for the polymer to be distributed more uniformly when entering the micropores.
Furthermore, the cavity and the micropore joint are provided with inclined planes, the inclined planes form a V shape, and the lower end of the inclined planes is connected with the upper end of the micropore. The polymer in the cavity can enter the micropores more smoothly under the guiding action of the inclined plane.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front sectional view of the present invention;
FIG. 2 is a front cross-sectional view of the spinneret orifice;
in the figure: 1. a spinneret plate body; 2. micropores; 3. a cavity; 4. a first feed port; 5. a second feed port; 31. a bevel.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model relates to a side-by-side melt-blown fabric spinneret plate, which comprises a spinneret plate body 1, wherein a plurality of micropores 2 are arranged on the filament outlet surface of the spinneret plate body 1, and as shown in fig. 2, two cavities 3 which are mutually separated and symmetrically arranged are connected to the upper ends of the micropores 2; the cavity 3 and the micropore 2 are connected with each other through inclined planes 31, the inclined planes 31 form a V shape, and the lower end of the inclined planes 31 is connected with the upper end of the micropore 2. The polymer in the cavity 3 can enter the micropores 2 more smoothly under the guiding action of the inclined surface 31.
The spinneret plate body 1 is further provided with a first feeding hole 4 and a second feeding hole 5 which are respectively communicated with the two cavities 3.
Two polymers with different properties respectively enter the cavity 3 from the first feeding hole 4 and the second feeding hole 5, enter the micropores 2 under the guiding action of the inclined plane 31, and lead out a strand of filaments with different properties from the micropores 2, so that the melt-blown fabric has more properties and better adsorption effect; the provision of the cavity 3 facilitates a more uniform distribution of the polymer as it enters the wells 2.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
