Description

Technical Field

[0001] The utility model relates to the field of spinning machine accessories, in particular to a short-pile spinneret. Background Art

[0002] The spinneret, also known as the spinning cap, has the main function of converting the viscous polymer melt or solution into thin streams with a specific cross-sectional shape through its tiny holes. These thin streams will solidify after passing through a coagulation medium (such as air or a coagulation bath), thereby forming fiber filaments. They are widely used in the textile, chemical and other fields, such as the production of textiles such as clothing, bedding, and curtains.

[0003] A traditional spinneret is usually a single circular plate structure with several micropores. During the production process, a viscous polymer melt or solution is extruded through the several micropores. However, in the actual production process, it is found that the polymer melt or solution transported by a pipeline is directly transported to the spinneret and extruded through several micropores. There is a common problem of uneven distribution of the polymer melt or solution, and the extrusion volume of the polymer melt or solution from some micropores is small, resulting in incomplete or broken filaments, affecting the quality of the filaments. For this reason, the present application proposes a short-pile spinneret. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a short-pile spinneret to solve the technical problem of uneven extrusion of polymer melt or solution in existing spinnerets.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] A short-pile spinneret, such as Figure 1-4 As shown, it includes a spinneret 1, on which multiple groups of spinnerets 5 are provided, a diverter cap 2 is provided on the top of the spinneret 1, and the diverter cap 2 is provided with a cone structure. A connecting pipe 3 is provided at the conical tip of the diverter cap 2, and a flange 4 is provided at the end of the connecting pipe 3 away from the diverter cap 2. Multiple diverter channels 14 are provided in the diverter cap 2, and the multiple diverter channels 14 are diffusely distributed in a cone-shaped manner in the diverter cap 2. The diverter channels 14 pass through one end surface where the diverter cap 2 is connected to the spinneret 1, and the number of the diverter channels 14 is the same as the number of the groups of spinnerets 5 and is aligned. The multiple branch channels 14 are all connected to the connecting pipe 3. Through this structural method, the flange 4 is used to connect the connecting pipe 3 with the polymer melt or solution delivery pipeline. After the viscous polymer melt or solution flows from the connecting pipe 3 into the diversion cap 2, it is evenly divided by the multiple branch channels 14. The multiple streams of viscous polymer melt or solution divided by the multiple branch channels 14 are transported to the multiple groups of spinneret holes 5 on the spinneret base plate 1 for extrusion, forming thin streams with specific cross-sections. After passing through the solidification medium, they are solidified to form velvet yarns, which are then cut into short fleece.

[0020] Furthermore, a conducting groove 10 is provided on the upper end surface of the spinneret base plate 1. The conducting groove 10 is provided in a circle and is distributed concentrically with the spinneret base plate 1. Multiple groups of spinneret holes 5 are evenly distributed in the conducting groove 10. Thus, the multiple groups of spinneret holes 5 are distributed in a ring shape, so that the extruded velvet is dispersed, which is more conducive to the condensation and solidification molding of the velvet. In addition, the multiple diversion channels 14 are diffusely distributed in a conical cylindrical shape in the diversion cap 2. Before the polymer melt or solution is extruded through the multiple groups of spinneret holes 5, it can be pre-uniformly diverted through the multiple diversion channels 14 to ensure that the polymer melt or solution can be evenly guided to the multiple groups of spinneret holes 5 for extrusion, thereby ensuring the uniformity of velvet production.

[0021] In a further embodiment, a boss 16 is provided on one end face where the diverter cap 2 is connected to the spinneret base plate 1, and the boss 16 is fitted into the conducting groove 10. The diverter channel 14 passes through the end face of the boss 16 and is used for sealing the diverter cap 2 and the spinneret base plate 1, wherein the thickness of the boss 16 is less than the depth of the conducting groove 10. Thus, after the spinneret base plate 1 and the diverter cap 2 are connected, there is a certain space between the spinneret hole 5 in the conducting groove 10 and the diverter channel 14, which can be used for the polymer melt or solution to be conducted in the conducting groove 10, thereby playing a role of secondary uniform dispersion.

[0022] Furthermore, a plurality of first connecting ear blocks 7 are provided on the outer peripheral wall of the spinneret base plate 1, a plurality of second connecting ear blocks 11 are provided on the outer peripheral wall of one end of the diverter cap 2 connected to the spinneret base plate 1, a connecting screw 12 is passed through the second connecting ear block 11, a screw hole 8 threadedly matched with the connecting screw 12 is provided on the first connecting ear block 7, a positioning groove 9 is provided on the upper surface of the first connecting ear block 7, a positioning protrusion 13 is provided on the lower surface of the second connecting ear block 11, the positioning protrusion 13 is fitly fitted with the positioning groove 9, a positioning through hole 6 is provided in the middle of the spinneret base plate 1, a positioning column 15 is provided in the middle of the end surface where the diverter cap 2 is connected to the spinneret base plate 1, and the positioning column 15 is plugged into the positioning through hole 6. Through the above structural method, the positioning connection of the spinneret base plate 1 and the diverter cap 2 can be realized.

[0023] The working principle of the utility model is as follows: when in use, the flange 4 is used to connect the connecting pipe 3 with the polymer melt or solution delivery pipeline. After the viscous polymer melt or solution flows from the connecting pipe 3 into the diversion cap 2, it is evenly divided by the multiple diversion channels 14. The multiple streams of viscous polymer melt or solution separated by the multiple diversion channels 14 are transported to the multiple groups of spinneret holes 5 on the spinneret base plate 1 for extrusion, forming a thin stream with a specific cross-section. After passing through the solidification medium, it solidifies to form velvet, and then after cutting, it is cut into pieces. After cutting, short pile is formed. In the overall structure, multiple groups of spinneret holes 5 are distributed in a ring shape, so that the extruded pile fibers are dispersed, which is more conducive to the condensation and solidification of the pile fibers. In addition, multiple diversion channels 14 are diffusely distributed in a cone shape in the diversion cap 2. Before the polymer melt or solution is extruded through the multiple groups of spinneret holes 5, it can be pre-uniformly diverted through the multiple diversion channels 14 to ensure that the polymer melt or solution can be evenly guided to the multiple groups of spinneret holes 5 for extrusion, thereby ensuring the uniformity of pile fiber production and improving product quality.
