Technical Field

[0001] This utility model relates to the field of annular spinnerets, and more particularly to an annular spinneret. Background Technology

[0002] In the chemical fiber and textile industry, a spinning device is typically used to extrude molten polymer or solution through spinnerets during the spinning process to form fibers, which are then used to make various textiles, such as clothing, home furnishings, and industrial materials.

[0003] An annular spinneret is typically a circular or ring-shaped plate with multiple tiny spinneret holes evenly distributed on its surface. Through these holes, molten or dissolved polymer is extruded and cooled, gradually forming fibers.

[0004] Considering that factors such as excessively high polymer viscosity, the presence of impurities, uneven temperature, chemical reactions, or prolonged use may cause the spinneret to become clogged, it is necessary to disassemble the spinneret device and remove the spinneret for cleaning. This process is complex, prone to errors, and may affect subsequent production. Therefore, a ring spinneret is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1- Figure 2 - One embodiment of this utility model provides: an annular spinneret, including a feed pipe 1. Spinnerets 2 are fixedly connected to the right and left sides of the outer surface of the bottom end of the feed pipe 1, providing fixed support for the spinnerets 2. A cleaning mechanism is provided on the inner surface of the spinnerets 2, including a cleaning insert 9. The outer surface of the cleaning insert 9 is fixedly connected to the top of the inner surface of the spinnerets 2, providing fixed support for the cleaning insert 9. A spinneret 10 is slidably connected to the inner surface of the spinneret chamber 2, allowing the spinneret 10 to move vertically along the inner surface of the spinneret chamber 2. A traction rod 3 is fixedly connected to the top of the outer surface of the spinneret 10, allowing the traction rod 3 to move the spinneret 10 together when it moves vertically. A first hinge rod 4 is hinged to the top of the outer surface of the traction rod 3, allowing the first hinge rod 4 to move the traction rod 3 vertically when it moves. A second hinge rod 5 is hinged to the middle of the inner surface of the first hinge rod 4, allowing the spinneret 10 to move vertically along the inner surface of the spinneret chamber 2. When the first hinge rod 4 is pressed down, the first hinge rod 4, due to its hinge with the second hinge rod 5, drives the traction rod 3 to maintain vertical movement. The bottom end of the outer surface of the second hinge rod 5 is hinged to the right side of the outer surface of the spinneret 2, allowing the second hinge rod 5 to rotate along the right side of the outer surface of the spinneret 2. The top of the outer surface of the traction rod 3 is elastically connected to the top of the outer surface of the spinneret 2 through spring A6, allowing the traction rod 3 to maintain downward movement without the influence of external force. The top of the outer surface of the traction rod 3 is slidably connected to the top of the inner surface of the spinneret 2, allowing the traction rod 3 to move vertically along the top of the inner surface of the spinneret 2. The bottom end of the outer surface of the cleaning insert 9 is inserted into the inner surface of the spinneret 10, allowing the spinneret 10 to clean the spinneret holes when it is inserted into the cleaning insert 9. The slidable connection between the outer surface of the traction rod 3 and the inner surface of the cleaning insert 9 prevents the cleaning insert 9 from moving vertically when the traction rod 3 moves vertically.

[0033] Reference Figure 2 - Figure 4A diversion chamber 7 is fixedly connected to the bottom of the outer surface of the feed pipe 1, providing fixed support for the diversion chamber 7. A diversion column 8 is rotatably connected to the inner surface of the diversion chamber 7, allowing the diversion column 8 to rotate along the inner surface of the diversion chamber 7. A column body 11 is fixedly connected to the inner surface of the diversion column 8, allowing the column body 11 to rotate along with the diversion column 8 when it rotates. The front and rear ends of the outer surface of the column body 11 are rotatably connected to the inner surface of the diversion chamber 7, allowing the column body 11 to rotate along the inner surface of the diversion chamber 7. A movable plate 16 is elastically connected to the front end of the inner surface of the column body 11 via a spring B15, allowing the movable plate 16 to always move inward without being affected by external forces. The outer surface of the movable plate 16 is slidably connected to the front end of the inner surface of the column body 11, allowing the movable plate 16 to move laterally along the front end of the inner surface of the column body 11. The left and right sides of the inner surface of the movable plate 16 are both penetrating... Furthermore, a snap-fit ​​component 12 is fixedly connected, enabling the snap-fit ​​component 12 to move together with the moving plate 16 when it moves laterally. A slot 13 is provided at the front end of the outer surface of the diversion chamber 7, allowing the rear end of the outer surface of the snap-fit ​​component 12 to snap into the front end of the outer surface of the diversion chamber 7. The inner surface of the slot 13 snaps into the rear end of the outer surface of the snap-fit ​​component 12, allowing the snap-fit ​​component 12 to fix the moving plate 16 at a specified angle when it snaps into the slot 13. A handle 14 is fixedly connected to the front end of the outer surface of the column 11, providing fixed support for the handle 14 and making it easier to rotate the column 11. The front end of the outer surface of the snap-fit ​​component 12 is slidably connected to the inner surface of the handle 14, allowing the snap-fit ​​component 12 to move laterally along the inner surface of the handle 14. When the handle 14 is gripped, the column 11 can be released by squeezing the snap-fit ​​component 12 and the handle 14.

[0034] Reference Figure 1 , Figure 4 - Figure 5One end of spring A6 is fixedly connected to the top of the outer surface of the traction rod 3, and the other end of spring A6 is fixedly connected to the top of the outer surface of the spinneret 2. This allows the traction rod 3 to move downwards due to the elastic force of spring A6 when the first hinge rod 4 is stopped being pressed down. One end of spring B15 is fixedly connected to the front end of the inner surface of the column 11, and the other end of spring B15 is fixedly connected to the rear end of the outer surface of the moving plate 16. This allows the moving plate 16 to move downwards due to the elastic force of spring B15 when the locking piece 12 is stopped being pulled. The coupling 12 moves inward and engages with the slot 13. The inner surface of the spinneret 2 has a feed inlet 17 on the left side, which allows the polymer in the feed pipe 1 to enter the spinneret 2 through the feed inlet 17. The inner surface of the feed inlet 17 is provided with a flow divider plate, which allows the polymer to enter the system more smoothly and reduces the accumulation effect. The spinneret 2 is provided with two sets, so that if one set fails, the material flow direction can be switched by the flow divider column 8 to avoid production stoppage due to single set failure and improve the overall production efficiency.

[0035] Working principle: When using the device, the polymer first enters the feed pipe 1, and then flows into a set of spinnerets 2 under the guidance of the diversion column 8. Then, a set of spinnerets 10 extrudes and cools the polymer, gradually forming fibers for subsequent processing.

[0036] When the spinneret 10 becomes clogged, simply press down the first hinge rod 4 to move the traction rod 3 upward, which in turn moves a set of spinnerets 10 upward. When it reaches the designated position, the spinneret 10 will engage with the cleaning insert 9, pushing out the polymer blockage inside the spinneret 10 to achieve the effect of unblocking and cleaning the spinneret 10. Then, release the first hinge rod 4, causing the traction rod 3 to move downward due to the elastic force of the spring A6, and causing the first hinge rod 4 and the spinneret 10 to reset.

[0037] When a set of spinnerets 2 is completely blocked or seriously malfunctions, without stopping the feeding of feed pipe 1, first hold the front end of handle 14 and clamp 12, then hold the two objects tightly, so that clamp 12 moves outward and engages with the front end of diverter 7. Then rotate column 11 to drive diverter column 8 to rotate to the designated position. Then release the front end of clamp 12, and then moving plate 16 will move inward due to the elastic force of spring B15, and drive the rear end of clamp 12 to engage with the slot 13 at the front end of diverter 7, fixing diverter column 8 in the designated position. Then the polymer in feed pipe 1 will flow into another set of spinnerets 2 along diverter column 8.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
