Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for spinning production, and in particular to a spinning assembly suitable for smaller diameter spinnerets. Background Technology

[0002] In PA6 or PA66 manufacturing enterprises, the spinneret is a key component of the spinning assembly, and the selection of its diameter is crucial for producing high-quality products of various specifications. Typically, companies design production lines tailored to the production capacity of different product specifications, usually matching spinnerets or spinning assemblies with different diameters. For example, some spinning assemblies have spinneret diameters of 50mm, 65mm, 77mm, and 88mm, with 24 or 34 holes, etc. However, the market for spun products is constantly changing, and the demand for different product specifications varies in different seasons. This often leads to situations where the production capacity cannot be arranged according to the original equipment design, resulting in situations where the nozzle diameter is suitable but the spinneret diameter is mismatched, preventing production from starting. Utility Model Content

[0003] The purpose of this invention is to provide a spinning assembly that is suitable for smaller diameter spinnerets, enabling smaller diameter spinnerets to be used in larger spinning assemblies, thus solving the problem of production failure caused by mismatched spinneret diameters.

[0004] The technical solution of this utility model:

[0005] A spinning assembly suitable for smaller diameter spinnerets includes an assembly housing. A spinneret is disposed on the lower end of the inner wall of the assembly housing via a jacket. An assembly sand cup is disposed above the spinneret. The bottom of the assembly sand cup is connected to the top of the spinneret via a sealing gasket. The sealing gasket isolates the gap between the spinneret and the jacket from the flow port of the assembly sand cup, preventing the melt from flowing out from the gap between the spinneret and the jacket.

[0006] Furthermore, an annular sealing groove for placing a sealing gasket is provided at the bottom of the component sand cup. The diameter of the annular sealing groove is smaller than the diameter of the spinneret, so that the sealing gasket isolates the gap between the spinneret and the jacket from the flow port of the component sand cup.

[0007] Furthermore, a guide plate is fixed inside the component sand cup below the metal sand, and the center of the bottom surface of the guide plate is connected to the guide port of the component sand cup; the guide plate has multiple flow channels, which extend from the top center to the side and finally to the bottom center. The melt flows along the flow channels on the guide plate to the bottom surface of the guide plate and finally merges at the center of the bottom surface of the guide plate.

[0008] Furthermore, the top of the component sand cup is connected to the component cap via a second sealing ring, and the top of the component cap is fixed with a sealing bushing that communicates with the flow port of the component cap.

[0009] Furthermore, a first limiting pin is fixed to the lower end of the inner wall of the component housing, and a first limiting groove for accommodating the first limiting pin is opened at the lower end of the outer wall of the sleeve; a second limiting pin is fixed to the lower end of the inner wall of the sleeve, and a second limiting groove for accommodating the second limiting pin is opened at the lower end of the outer wall of the spinneret.

[0010] Furthermore, a locking sleeve is provided on the top of the component cover, and the outer wall of the locking sleeve is threadedly connected to the upper end of the inner wall of the component housing.

[0011] Furthermore, the locking sleeve has multiple insertion holes that assist in the rotation of the locking sleeve.

[0012] The beneficial effects of this utility model are:

[0013] (1) A smaller diameter spinneret can be used in a larger spinning assembly by means of a jacket. A sealing gasket isolates the gap between the spinneret and the jacket from the flow port of the assembly sand cup, preventing the melt from flowing out from the gap between the spinneret and the jacket.

[0014] (2) The guide plate has multiple flow channels that extend from the top center to the side and finally to the bottom center. The bottom surface of the guide plate is a frustum. The melt flows along the flow channels on the guide plate to the bottom surface of the guide plate and finally converges at the center of the bottom surface of the guide plate to fuse, ensuring the uniformity of the melt. Finally, the melt after fusion is spun through a spinneret to ensure that the composition content of each filament is kept as similar as possible.

[0015] This invention enables smaller diameter spinnerets to be used in larger spinning assemblies, improving the applicability of spinnerets when scheduling production varieties. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1-3 As shown, this utility model provides a first embodiment of a spinning assembly suitable for smaller diameter spinnerets, including an assembly housing 1. A spinneret 3 is mounted on the lower end of the inner wall of the assembly housing 1 via a jacket 2, allowing the smaller diameter spinneret 3 to be used in a larger spinning assembly. An assembly sand cup 4 is positioned above the spinneret 3; the bottom of the assembly sand cup 4 is connected to the top of the spinneret 3 via a sealing gasket 5. The sealing gasket 5 isolates the gap between the spinneret 3 and the jacket 2 from the flow port of the assembly sand cup 4, preventing melt from flowing out from the gap between the spinneret 3 and the jacket 2.

[0025] The bottom of the component sand cup 4 has an annular sealing groove 41 for placing a sealing gasket 5. The diameter of the annular sealing groove 41 is smaller than the diameter of the spinneret 3, so that the sealing gasket 5 isolates the gap between the spinneret 3 and the jacket 2 from the flow port of the component sand cup 4. By filling the annular sealing groove 41 with the sealing gasket 5, the melt is blocked by the sealing gasket 5 and cannot flow into the gap between the spinneret 3 and the jacket 2 and flow out.

[0026] Based on the previous embodiment, this utility model provides a second embodiment. A guide plate 6 is fixed inside the component sand cup 4 below the metal sand 42. The center of the bottom surface of the guide plate 6 is connected to the flow port of the component sand cup 4. The guide plate 6 has multiple flow channels 61 extending from the top center to the side and finally to the bottom center. The bottom surface of the guide plate 6 is a frustum. The melt flows along the flow channels 61 on the guide plate 6 to the bottom surface of the guide plate 6 and finally converges at the center of the bottom surface of the guide plate 6. When the melt passes through the metal sand 42, it is separated into multiple melt streams. These streams are then filtered through the metal sand 42. Because the filtration effect of the multiple melt streams through the metal sand 42 is different, the composition content of each melt stream is also different. Therefore, the guide plate 6 is needed to fuse the multiple melt streams to ensure the uniformity of the melt. Finally, the fused melt is spun through the spinneret 3 to ensure that the composition content of each resulting filament bundle remains as similar as possible.

[0027] Based on any of the above embodiments, the present invention provides a third embodiment in which the top of the component sand cup 4 is connected to the component cover 9 via the second sealing ring 7. The top of the component cover 9 is fixed with a sealing bushing 8 that communicates with the flow port of the component cover 9. The melt flows into the spinning component from the sealing bushing 8, passes through the flow port of the component cover 9, and flows through the ring of the second sealing ring 7 into the metal sand 42.

[0028] like Figures 4-6 As shown, based on any of the above embodiments, this utility model provides a fourth embodiment. A first limiting pin 101 is fixed to the lower end of the inner wall of the component housing 1, and a first limiting groove 201 is provided at the lower end of the outer wall of the sleeve 2 to accommodate the first limiting pin 101. Through the cooperation of the first limiting pin 101 and the first limiting groove 201, the component housing 1 can limit the sleeve 2 and prevent the sleeve 2 from rotating. A second limiting pin 202 is fixed to the lower end of the inner wall of the sleeve 2, and a second limiting groove 301 is provided at the lower end of the outer wall of the spinneret 3 to accommodate the second limiting pin 202. Through the cooperation of the second limiting pin 202 and the second limiting groove 301, the sleeve 2 can limit the spinneret 3 and prevent the spinneret 3 from rotating.

[0029] Based on the third embodiment, this utility model provides a fifth embodiment, wherein a locking sleeve 10 is provided on the top of the component cover 9, the outer side wall of the locking sleeve 10 is threadedly connected to the upper end of the inner wall of the component housing 1, the outer side wall of the locking sleeve 10 has an external thread, and the inner wall of the component housing 1 has a matching internal thread. The locking sleeve 10 can press and seal the component cover 9, the component sand cup 4, the spinneret 3 and the clamp 2 inside the component housing 1.

[0030] A press is used to press the component cap 9, component sand cup 4, spinneret 3, and jacket 2 downwards. Because the lower inner wall of the component housing 1, the inner and outer walls of the jacket 2, and the lower outer wall of the spinneret 3 are all stepped and interlocking, the jacket 2 and spinneret 3 are prevented from detaching from the component housing 1 during the press. After press, the locking sleeve 10 is rotated to press and seal the component cap 9, component sand cup 4, spinneret 3, and jacket 2 within the component housing 1. During the press, the pressing force of the press is 20MPa-30MPa, causing the sealing gasket 5 to deform and fill the annular sealing groove 41, thus achieving a sealing effect.

[0031] Based on the previous embodiment, the present invention provides a sixth embodiment, wherein the locking sleeve 10 has a plurality of insertion holes (not shown) for assisting the rotation of the locking sleeve 10. The insertion holes are used to facilitate the rotation of the locking sleeve 10 after the disassembly tool is inserted, thereby facilitating disassembly and assembly.

[0032] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
