Description

Technical Field

[0001] This utility model relates to the field of fiber spinnerets, specifically a spinneret for matte two-component composite elastic fibers. Background Technology

[0002] A spinneret, also known as a spinning cap, is used to transform viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores. These streams are then solidified by a coagulation medium such as air or a coagulation bath to form filaments. In the production of matte bicomponent composite elastic fibers, the raw material is extruded through meltblown pipes under pressure and comes into contact with multiple micropores on the spinneret, where it is then extruded to form filaments.

[0003] During operation, spinnerets are prone to clogging due to their small nozzle diameter. When clogged, the spinneret needs to be disassembled and replaced before a clean spinneret can be used, affecting the production progress. Therefore, a special spinneret for matte two-component composite elastic fibers is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The special spinneret for matte bicomponent composite elastic fiber of this utility model includes a meltblown pipe, a toothed ring threadedly connected to the outside of the meltblown pipe, a gear meshing with the outside of the toothed ring, a drive motor fixedly connected to the outside of the meltblown pipe, the output end of the drive motor fixedly connected to the gear, a sealing plate rotatably connected to the inside of the toothed ring, a spinneret fixedly connected to the inside of the sealing plate, a fixing frame fixedly connected to the inside of the meltblown pipe, and an insert rod fixedly connected to the outside of the fixing frame; this step involves setting the toothed ring, gear, sealing plate, spinneret, and insert rod. In use, the sealing plate is inserted into the inside of the meltblown pipe to fix the positions of the sealing plate and the spinneret. At the same time, the gear ring is rotated so that it is screwed onto the outside of the meltblown pipe. Then, the molten material is extruded through the meltblown pipe and through the spinneret. When the spinneret becomes clogged, the drive motor drives the gear and the gear ring to rotate. The gear ring drives the sealing plate and the spinneret to move, so that the insert rod is inserted into the hole groove on the surface of the spinneret, thereby quickly pushing out the material that is blocked inside. Then, the solidified material is wiped off, and the spinneret is returned to its position to continue working. This allows for quick unblocking of the spinneret without the need for replacement, improving the stability of the equipment's production.

[0006] Preferably, a square rod is fixedly connected to the outside of the gear, a round rod is slidably connected to the outside of the square rod, and an elastic plate is fixedly connected to the outside of the round rod. The round rod and the sealing plate are rotatably connected. In this step, by setting up the square rod, round rod, and elastic plate, when the gear ring drives the sealing plate and the spinneret to move, the gear will simultaneously drive the square rod and the round rod to rotate. The round rod drives one end of the elastic plate to be thrown to the outside of the sealing plate and then separated, which vibrates the sealing plate to a certain extent. This causes the solidified raw material to also be vibrated, thereby causing part of the solidified raw material to separate from the spinneret, making it easier for the insertion rod to push it out, thus improving the stability of the device.

[0007] Preferably, a fixing plate is fixedly connected to the outside of the meltblown pipe, an adjusting screw is threadedly connected to the outside of the fixing plate, and a baffle is fixedly connected to the outside of the adjusting screw. This step, by setting the fixing plate, adjusting screw, and baffle, allows the adjusting screw to rotate after the gear ring is screwed onto the outside of the meltblown pipe. This causes the adjusting screw to drive the baffle to rotate onto the movement trajectory of the gear ring, thereby cooperating with the fixing plate to block both sides of the gear ring, further restricting the movement range of the gear ring and improving the stability of the device operation.

[0008] Preferably, buffer pads are fixedly connected to the outer side of the fixed plate and the outer side of the baffle. The buffer pads work together with the toothed ring. By setting the buffer pads, when the toothed ring moves to contact the fixed plate and the baffle, the buffer pads separate it from the fixed plate and the baffle, making it less likely to be damaged by hard collision, thus improving the stability of the device.

[0009] Preferably, a limiting plate is fixedly connected to the outside of the adjusting screw, and the limiting plate and the fixing plate are used together. This step, by setting the limiting plate, ensures that after the adjusting screw moves to the maximum position, it is blocked and restricted by the limiting plate, making it difficult for it to separate from the fixing plate, thus improving the stability of the device.

[0010] Preferably, a push rod is slidably connected to the inner side of the sealing plate, and a scraper is fixedly connected to the outer side of the push rod. By setting the push rod and scraper, after the insert rod pushes out the solidified raw material inside the spinneret, the push rod can be pushed, and the push rod drives the scraper to push the solidified raw material to separate from the spinneret, thereby completing the rapid cleaning and further improving the convenience of cleaning the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a gear ring, gears, sealing plate, spinneret, and insert rod, allows for the following operation: During use, the sealing plate is inserted into the inside of the meltblown pipe to fix the positions of the sealing plate and spinneret. Simultaneously, the gear ring is rotated to screw onto the outside of the meltblown pipe. The molten material is then extruded through the spinneret via the meltblown pipe. If the spinneret becomes clogged, a drive motor rotates the gears and gear ring, which in turn moves the sealing plate and spinneret, allowing the insert rod to be inserted into the slots on the surface of the spinneret. This quickly pushes out the clogged material. The solidified material is then wiped off, and the spinneret is returned to its original position to continue operation. This method allows for rapid unclogging of the spinneret without replacement, improving the stability of the equipment's production.

[0013] 2. This utility model, by setting up a square rod, a round rod, and an elastic plate, allows the gear to simultaneously drive the square rod and the round rod to rotate when the gear ring moves the sealing plate and the spinneret. The round rod then causes one end of the elastic plate to be thrown to the outside of the sealing plate and then separated, vibrating the sealing plate to a certain extent. This vibration causes the solidified raw material to also be vibrated, thereby causing some of the solidified raw material to separate from the spinneret, making it easier for the insertion rod to push it out, thus improving the stability of the device.

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, a special spinneret for matte bicomponent composite elastic fiber includes a meltblown pipe 1. A gear ring 2 is threadedly connected to the outside of the meltblown pipe 1, and a gear 3 meshes with the outside of the gear ring 2. A drive motor 4 is fixedly connected to the outside of the meltblown pipe 1, and the output end of the drive motor 4 is fixedly connected to the gear 3. A sealing plate 5 is rotatably connected to the inside of the gear ring 2, and a spinneret 6 is fixedly connected to the inside of the sealing plate 5. A fixing frame 7 is fixedly connected to the inside of the meltblown pipe 1, and an insertion rod 8 is fixedly connected to the outside of the fixing frame 7. This step involves setting up the gear ring 2, gear 3, sealing plate 5, spinneret 6, and insertion rod 8. In use, the sealing plate 5 is inserted... The sealing plate 5 and the spinneret 6 are fixed inside the meltblown pipe 1. At the same time, the gear ring 2 is rotated so that it is screwed onto the outside of the meltblown pipe 1. Then, the molten material is extruded through the spinneret 6 through the meltblown pipe 1. When the spinneret 6 is blocked, the drive motor 4 drives the gear 3 and the gear ring 2 to rotate. The gear ring 2 drives the sealing plate 5 and the spinneret 6 to move, so that the insert rod 8 is inserted into the hole groove on the surface of the spinneret 6, thereby quickly pushing out the material blocked inside. Then, the solidified material is wiped off, and the spinneret 6 is returned to its position to continue working. This allows the spinneret 6 to be quickly unblocked without replacement, improving the stability of the equipment's production.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, a square rod 9 is fixedly connected to the outside of the gear 3, a round rod 10 is slidably connected to the outside of the square rod 9, and an elastic plate 11 is fixedly connected to the outside of the round rod 10. The round rod 10 and the sealing plate 5 are rotatably connected. In this step, by setting up the square rod 9, the round rod 10 and the elastic plate 11, when the gear ring 2 drives the sealing plate 5 and the spinneret 6 to move, the gear 3 will simultaneously drive the square rod 9 and the round rod 10 to rotate. The round rod 10 drives one end of the elastic plate 11 to be thrown to the outside of the sealing plate 5 and then separated, which vibrates the sealing plate 5 to a certain extent, so that the solidified raw material is also vibrated, thereby causing part of the solidified raw material to separate from the spinneret 6, making it easier for the insertion rod 8 to push it out, thus improving the stability of the device.

[0025] Furthermore, such as Figure 1 As shown, a fixing plate 12 is fixedly connected to the outside of the meltblown pipe 1, and an adjusting screw 13 is threadedly connected to the outside of the fixing plate 12. A baffle 14 is fixedly connected to the outside of the adjusting screw 13. In this step, by setting the fixing plate 12, adjusting screw 13, and baffle 14, after the gear ring 2 is screwed onto the outside of the meltblown pipe 1, the adjusting screw 13 is rotated, causing the adjusting screw 13 to drive the baffle 14 to rotate onto the movement trajectory of the gear ring 2. This, in conjunction with the fixing plate 12, blocks both sides of the gear ring 2, further restricting the movement range of the gear ring 2 and improving the stability of the device operation.

[0026] Furthermore, such as Figure 1 As shown, buffer pads 15 are fixedly connected to the outer side of the fixed plate 12 and the outer side of the baffle 14. The buffer pads 15 and the toothed ring 2 are used together. By setting the buffer pads 15, when the toothed ring 2 moves to contact the fixed plate 12 and the baffle 14, the buffer pads 15 separate it from the fixed plate 12 and the baffle 14, making it less likely to be damaged by hard collision, thus improving the stability of the device.

[0027] Furthermore, such as Figure 1 As shown, a limiting plate 16 is fixedly connected to the outside of the adjusting screw 13. The limiting plate 16 and the fixing plate 12 are used together. By setting the limiting plate 16, the adjusting screw 13 is blocked and restricted by the limiting plate 16 after it moves to the maximum position, making it difficult for it to separate from the fixing plate 12, thus improving the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a push rod 17 is slidably connected to the inner side of the sealing plate 5, and a scraper 18 is fixedly connected to the outer side of the push rod 17. In this step, by setting the push rod 17 and the scraper 18, after the insert rod 8 pushes out the solidified raw material inside the spinneret 6, the push rod 17 can be pushed. The push rod 17 drives the scraper 18 to push the solidified raw material to separate from the spinneret 6, thereby completing the rapid cleaning and further improving the convenience of cleaning the device.

[0029] Working principle: During use, the sealing plate 5 is inserted into the inside of the meltblown pipe 1 to fix the positions of the sealing plate 5 and the spinneret 6. At the same time, the gear ring 2 is rotated so that it is screwed onto the outside of the meltblown pipe 1. Then, the molten material is extruded through the meltblown pipe 1 and through the spinneret 6. When the spinneret 6 becomes clogged, the drive motor 4 drives the gear 3 to rotate, which in turn drives the gear ring 2 to rotate. The gear ring 2 then moves the sealing plate 5 and the spinneret 6, allowing the insert rod 8 to be inserted into the slot on the surface of the spinneret 6, thereby quickly pushing out the material that is clogged inside. Then, the push rod 17 is pushed, which drives the scraper 18 to move. The scraper 18 wipes off the solidified material and pulls it away from the spinneret 6 for cleaning. Then, the push rod 17 without the scraper 18 is inserted back into the inside of the sealing plate 5 to return it to its original position. The spinneret 6 is then returned to its original position, and the operation can continue.
