Description

Technical Field

[0001] The utility model relates to the technical field of spinnerets, in particular to a spinneret structure. Background Art

[0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through micropores, and solidify it into a filament through a coagulation medium such as air or a coagulation bath.

[0003] At present, in the design of traditional spinnerets, the feed port is usually set at the center of the spinneret. After the melt or solution enters the spinneret from the middle feed port, the spinning often becomes uneven due to the difference in feeding speed between the middle and the two ends, affecting the quality and production efficiency of the fiber. In practice, in order to solve the problem of uneven spinning, a common practice in the prior art is to directly not set spinnerets at both ends of the spinneret, in order to try to achieve the effect of uniform spinning. However, although this method is simple and easy to deal with the uniformity of spinning, it is achieved by sacrificing the number of spinnerets, which affects the overall production efficiency and fails to fundamentally solve the spinning problem caused by uneven feeding. Utility Model Content

[0004] In view of the fact that in the prior art, although this method of processing the uniformity of spinning is simple and easy, it is achieved by sacrificing the number of spinneret holes, which affects the overall production efficiency and fails to fundamentally solve the spinning problem caused by uneven feeding, the main purpose of the present utility model is to provide a spinneret structure.

[0005] The technical solution of the present utility model is as follows: a spinneret structure comprises a spinneret body, an upper plate is provided at the top of the spinneret body, a feed pipe is fixedly connected to the top of the upper plate, an eccentric feed port is provided inside the upper plate and below the feed pipe, the internal array of the spinneret body is provided with spinneret holes, an anti-sticking tube is fixedly connected to the bottom of the spinneret body and below the spinneret holes, a mounting mechanism is provided on the outer side of the spinneret body and the upper plate, and a sealing mechanism is provided between the spinneret body and the upper plate.

[0006] By adopting the above technical solution, the feed port is designed as an eccentric structure instead of the traditional central position. By optimizing the layout and shape of the feed port, the melt or solution can be more evenly distributed before entering the spinneret. At the same time, the arrangement and design of the spinneret holes are also specially optimized to ensure that the fibers ejected from each hole have consistent diameter and speed.

[0007] As a preferred embodiment, the mounting mechanism includes two mounting plates 1 fixedly connected to both sides of the upper plate, the interior of the mounting plate 1 is threadedly connected with a locking bolt, and two mounting plates 2 are fixedly connected to both sides of the spinneret body, the interior of the mounting plate 2 is provided with a screw hole, and the bottom end of the mounting plate 2 is provided with a locking nut, the locking nut is threadedly connected to the corresponding locking bolt, and the outer side of the locking nut is in conflict with the bottom end of the corresponding mounting plate 2.

[0008] By adopting the above technical solution, the fixed state between the spinneret body and the upper plate can be unlocked by twisting the locking nut, so that a spinneret body with spinneret holes of different diameters can be selected according to different production conditions.

[0009] As a preferred embodiment, a positioning mechanism is provided between the spinneret body and the upper plate, the positioning mechanism includes a positioning frame fixedly connected to the bottom end of the upper plate, a positioning groove body is provided inside the spinneret body for use with the positioning frame, and the positioning frame is engaged with the positioning groove body.

[0010] By adopting the above technical solution and using the positioning frame in conjunction with the positioning groove, the connection between the upper plate and the spinneret body can be made more stable.

[0011] As a preferred embodiment, the sealing mechanism includes a sealing frame fixedly connected to the bottom end of the positioning frame, and a sealing groove body used in conjunction with the sealing frame is provided inside the spinneret body and below the positioning groove body, and the sealing frame is engaged with the sealing groove body.

[0012] By adopting the above technical solution and using the sealing frame and the sealing groove body in combination, the sealing performance between the spinneret body and the upper plate can be improved.

[0013] As a preferred embodiment, the inner walls of the spinneret body and the upper plate are both coated with high-temperature resistant material.

[0014] By adopting the above technical solution, the high temperature resistance of the spinneret body and the upper plate is increased.

[0015] As a preferred embodiment, the spinneret hole and the inner wall of the anti-sticking tube are both provided with a smooth layer.

[0016] By adopting the above technical solution, the adhesion phenomenon of the melt or solution is reduced, so that the melt or solution is discharged more evenly.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are:

[0018] 1. In the present invention, the feed port is designed as an eccentric structure rather than the traditional central position. By optimizing the layout and shape of the feed port, the melt or solution can be more evenly distributed before entering the spinneret. At the same time, the arrangement and design of the spinneret holes are also specially optimized to ensure that the fibers ejected from each hole have consistent diameter and speed. The anti-sticking tube is set to avoid adhesion of the spinneret before it is completely solidified, thereby reducing the impact on product quality.

[0019] 2. In the present invention, when it is necessary to replace the spinneret body with spinneret holes of different diameters, the locking nut can be screwed and the locking bolt can be removed from the screw hole, thereby unlocking the fixed state between the spinneret body and the upper plate. In this way, the spinneret body with spinneret holes of different diameters can be selected according to different production conditions, thereby improving the practicality of the spinneret body.

At the same time, the arrangement and design of the spinneret holes 7 have also been specially optimized to ensure that the fibers ejected from each hole have consistent diameter and speed, and the setting of the anti-sticking tube 8 can avoid adhesion of the spinneret before it is completely solidified, thereby reducing the impact on product quality.

[0027] Reference Figure 2 The mounting mechanism 6 includes two mounting plates 601 fixedly connected to both sides of the upper plate 2, and the interior of the mounting plate 1 601 is threadedly connected with locking bolts 602.

In this way, the spinneret body 1 with spinneret holes 7 of different diameters can be selected according to different production conditions, thereby improving the practicality of the spinneret body 1.
