Description

Technical Field

[0001] This invention relates to the field of spinning technology, and in particular to a shaped fiber spinneret and spinning assembly. Background Technology

[0002] In chemical fiber production, process technology and spinning equipment are two major factors affecting production. With the continuous updating of spinning processes and equipment, high-speed and high-pressure spinning technologies are widely used in production. In melt spinning, the spinning assembly, also known as the spinning head, functions to finely filter, fully mix, and evenly distribute the polymer melt, and then extrude it into filaments through the micropores of the spinneret under certain pressure.

[0003] After the spinning solution or melt enters the spinning machine, the spinning pump uses a spinning pump to press out the spinning solution or melt quantitatively, continuously and uniformly from the fine orifice of the spinneret. However, the molten polymer delivered by the spinning pump through the melt pipeline is at a high temperature. The high temperature of the molten polymer can easily damage the spinneret and the filter screen, thus affecting the entire spinning process and reducing the fiber quality. Summary of the Invention

[0004] This invention discloses a shaped fiber spinneret, aiming to solve the technical problem in the prior art where, after the spinning solution or melt enters the spinning machine, the spinning pump quantitatively, continuously, and uniformly presses the spinning solution or melt out from the fine orifice of the spinneret. However, the molten polymer delivered by the spinning pump through the melt pipeline is at a high temperature. The high-temperature molten polymer can easily damage the spinneret and the filter screen, thereby affecting the entire spinning process and reducing fiber quality.

[0005] The present invention proposes an irregularly shaped fiber spinneret, comprising a spinneret body, wherein a plurality of irregularly shaped spinneret holes are equally spaced at the bottom of the spinneret body.

[0006] A spinning assembly using a profiled fiber spinneret as described above, further comprising a cooling assembly and a spinning platform. The cooling assembly includes a mounting support plate and a spinning pump. One side of the mounting support plate has an installation port, inside which a cooling cylinder is fixedly connected. One side of the cooling cylinder has a circular hole (or similar opening). Inside the circular hole (or similar opening) is a hollow rotating frame connected via a bearing. A linkage support plate is fixedly connected to the outside of the hollow rotating frame, located inside the cooling cylinder. One side of the linkage support plate has two circular holes (or similar openings) at equal intervals. Each circular hole (or similar opening) has an air blower fixedly connected inside. Multiple air blowers on the same side are fixedly connected to the same hollow connecting plate. One side of both the hollow connecting plate and the hollow rotating frame has a circular hole (or similar opening). Two circular holes (or similar openings) are fixedly connected to the same conveying pipe. A circular hole four is provided on one side of the rotating circular frame. An air blower is fixedly connected inside the circular hole four. A hose is fixedly connected to one side of the air blower. A pump body is fixedly connected to the air inlet end of the hose. A filter head is fixedly connected to the air inlet end of the pump body. A circular hole two is provided at equal intervals on one side of the linkage support plate. An air blower head is fixedly connected inside each circular hole two. A hollow connecting plate is fixedly connected to one side of multiple air blowers located on the same side. A circular hole three is provided on one side of both the hollow connecting plate and the hollow rotating circular frame. A delivery pipe is fixedly connected inside two circular holes three. A circular hole four is provided on one side of the hollow rotating circular frame. An air blower is fixedly connected inside the circular hole four. A hose is fixedly connected to one side of the air blower. A pump body is fixedly connected to the air inlet end of the hose. A filter head is fixedly connected to the air inlet end of the pump body.

[0007] In a preferred embodiment, a guide rail is fixedly connected to one side of the cooling cylinder, and a toothed rod is slidably connected inside the guide rail. A telescopic cylinder is fixedly connected to one side of the toothed rod, and a rotating gear is fixedly connected to the outside of the hollow rotating frame. The rotating gear meshes with the toothed end of the toothed rod.

[0008] In a preferred embodiment, a discharge hole is provided on one side of the cooling cylinder, and a discharge pipe is fixedly connected inside the discharge hole. A pressure pump is fixedly connected to one side of the discharge pipe. A spiral discharge plate is fixedly connected inside the cooling cylinder. A melt feed pipe is fixedly connected to the inlet end of the spinning pump, and a conduit is fixedly connected to the outlet end of the spinning pump.

[0009] Equipped with a cooling component, the spinning solution or melt enters the cooling cylinder through the melt feed pipe. The pump is then activated, and the pump, via a hose, blows gas purified by the filter head into the hollow rotating frame. Multiple air blowers on the hollow connecting plate then cool the spinning solution or melt. Simultaneously, a telescopic cylinder is activated, driving a rack to reciprocate within the guide rail. This rack drives a rotating gear to rotate bidirectionally, which in turn drives a linkage plate on the hollow rotating frame to rotate bidirectionally. This bidirectional rotation of the air blowers uniformly cools the spinning solution or melt. Simultaneously, the feeding speed of the spinning solution or melt is controlled by a spiral feed plate as the cooling cylinder moves, resulting in better cooling. The cooling component reduces the temperature of the molten polymer delivered by the spinning pump through the melt pipe, thereby reducing damage to the spinneret, improving the entire spinning process, and ultimately enhancing fiber quality.

[0010] In a preferred embodiment, a screening assembly is provided directly below the feed pipe, and the screening assembly includes a sealed screening frame and a mounting base.

[0011] In a preferred embodiment, telescopic springs are fixedly connected at equal distances to the opposite sides of the sealed sieve frame, and the same sieve plate is fixedly connected to the outside of the multiple telescopic springs. Sliding openings are provided on both sides of the sealed sieve frame, and lifting impact blocks are slidably connected inside the two sliding openings. One side of the lifting impact block is fixedly connected to one side of the sieve plate.

[0012] In a preferred embodiment, a drive motor is fixedly connected to one side of each of the two mounting bases, and the drive end of each drive motor is connected to a rotating circular plate via a coupling. A circular hole five is provided on one side of each of the two lifting impact blocks and one side of each of the two rotating circular plates. A rotating shaft is connected inside each circular hole five via a bearing, and the same push-pull rod is movably connected to the outside of the two rotating shafts located on the same side.

[0013] By incorporating a sieving component, the molten polymer is sieved through a sieve plate during the spinning process, preventing impurities in the molten polymer from clogging the spinneret. Simultaneously, the drive motor is activated, which rotates a circular plate. This rotating plate, in turn, drives a push-pull rod to move a lifting impact block up and down within the slide rail of the sealed sieve frame. Consequently, the lifting impact block causes the sieve plate to vibrate up and down, preventing impurities separated during the sieving process from clogging the sieve plate and affecting sieving efficiency.

[0014] In a preferred embodiment, a cleaning component is provided on the outside of the sealed sieve frame, and the cleaning component includes a fixing plate. The same guide rod is fixedly connected to the opposite side of the two fixing plates, and the same movable slide is slidably connected to the outside of the two guide rods.

[0015] In a preferred embodiment, a scraper is fixedly connected to one side of the movable slide, and a cleaning brush is fixedly connected to one side of the scraper. A push rod is fixedly connected to one side of the movable slide.

[0016] With the cleaning components installed, when the spinneret is not in use, the operator can move the movable slide outside the guide rod by pushing and pulling the push rod. This allows the scraper on the movable slide to scrape away the debris remaining on the surface of the spinneret, while the cleaning brush cleans the surface of the spinneret.

[0017] In a preferred embodiment, two support frames are fixedly connected to one side of the spinning platform by bolts. The same outer shell is fixedly connected to the opposite side of the two support frames. An observation port is opened on one side of the outer shell, and a transparent observation window is fixedly connected to one side of the observation port. Two movable brackets are fixedly connected to one side of the spinning platform.

[0018] As can be seen from the above, the shaped fiber spinneret provided by the present invention has the beneficial effect of reducing the temperature of the molten polymer delivered by the spinning pump through the melt pipeline, thereby reducing the damage caused by the molten polymer to the spinneret, improving the entire spinning process, and thus improving the fiber quality.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The shaped fiber spinneret disclosed in this invention is mainly used in spinning machines after the spinning solution or melt enters the spinning machine. The spinning pump presses the spinning solution or melt quantitatively, continuously and uniformly out of the fine holes of the spinneret. However, the molten polymer delivered by the spinning pump through the melt pipeline has a high temperature. The high temperature molten polymer can easily damage the spinneret and the filter screen, thereby affecting the entire spinning process and reducing the fiber quality.

[0031] Reference Figure 2 and Figure 3A spinning assembly using a profiled fiber spinneret as described above, further comprising a cooling assembly 6 and a spinning platform 2. The cooling assembly 6 includes a mounting plate 601 and a spinning pump 604. A mounting port is provided on one side of the mounting plate 601, and a cooling cylinder 602 is fixedly connected inside the mounting port. A circular hole is provided on one side of the cooling cylinder 602, and a hollow rotating circular frame 607 is connected inside the circular hole 607 via a bearing. A linkage support plate 608 is fixedly connected to the outside of the hollow rotating circular frame 607, and the linkage support plate 608 is located inside the cooling cylinder 602. Circular holes are provided at equal intervals on one side of the linkage support plate 608. Each of the holes has an air blower head 609 fixedly connected inside. The same hollow connecting plate 610 is fixedly connected to one side of the multiple air blowers 609 located on the same side. The hollow connecting plate 610 and the hollow rotating frame 607 each have a circular hole 3 on one side. The same conveying pipe 611 is fixedly connected inside the two circular holes 3. A circular hole 4 is opened on one side of the hollow rotating frame 607. An air blower pipe 616 is fixedly connected inside the circular hole 4. A hose 617 is fixedly connected to one side of the air blower pipe 616. A pump body 618 is fixedly connected to the air inlet end of the hose 617. A filter head 619 is fixedly connected to the air inlet end of the pump body 618.

[0032] Reference Figure 2 and Figure 3 A guide rail 612 is fixedly connected to one side of the cooling cylinder 602, and a rack 614 is slidably connected inside the guide rail 612. A telescopic cylinder 615 is fixedly connected to one side of the rack 614. A rotating gear 613 is fixedly connected to the outside of the hollow rotating frame 607, and the rotating gear 613 meshes with the tooth block end of the rack 614.

[0033] Reference Figure 2 and Figure 3 A discharge hole is provided on one side of the cooling cylinder 602, and a discharge pipe 620 is fixedly connected inside the discharge hole. A pressure pump 621 is fixedly connected to one side of the discharge pipe 620. A spiral discharge plate 606 is fixedly connected inside the cooling cylinder 602. A melt feed pipe 603 is fixedly connected to the feed end of the spinning pump 604, and a conduit 605 is fixedly connected to the discharge end of the spinning pump 604.

[0034] In specific application scenarios, after the spinning solution or melt enters the cooling cylinder 602 through the melt feed pipe 603, the pump body 618 is activated. The pump body 618 blows the gas purified by the filter head 619 into the hollow rotating frame 607 through the hose 617. Then, the multiple air blowers 609 on the hollow connecting plate 610 blow the spinning solution or melt to cool it down. At the same time as blowing the gas, the telescopic cylinder 615 is activated. The telescopic cylinder 615 drives the rack 614 to move back and forth inside the guide rail 612, thereby causing the rack 614 to drive the rotating gear 613 in both directions. The rotation, driven by the rotating gear 613, causes the linkage support plate 608 on the hollow rotating frame 607 to rotate in both directions, which in turn causes the air blower head 609 to rotate in both directions to uniformly blow air and cool the textile solution or melt. At the same time, as the textile solution or melt moves in the cooling cylinder 602, its feeding speed is controlled by the spiral feed plate 606 to achieve a better cooling effect. Through the cooling component 6, the temperature of the molten polymer delivered by the spinning pump 604 through the melt pipeline is reduced, thereby reducing the damage caused by the molten polymer to the spinneret, improving the entire spinning process, and thus improving fiber quality.

[0035] Reference Figure 2 , Figure 3 and Figure 4 A screening component 7 is provided directly below the feed pipe 620, and the screening component 7 includes a sealed screening frame 701 and a mounting base 706.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The sealed sieve frame 701 is fixedly connected to the opposite sides at equal distances with telescopic springs 702, and the same sieve plate 703 is fixedly connected to the outside of multiple telescopic springs 702. The sealed sieve frame 701 has sliding openings on both sides, and lifting impact blocks 704 are slidably connected inside the two sliding openings. One side of the lifting impact block 704 is fixedly connected to one side of the sieve plate 703.

[0037] Reference Figure 2 , Figure 3 and Figure 4 A drive motor 707 is fixedly connected to one side of each of the two mounting bases 706, and the drive end of each drive motor 707 is connected to a rotating circular plate 708 via a coupling. A circular hole 5 is provided on one side of each of the two lifting impact blocks 704 and one side of each of the two rotating circular plates 708. A rotating shaft 705 is connected inside each circular hole 5 via a bearing. The same push-pull rod 709 is movably connected to the outside of the two rotating shafts 705 located on the same side.

[0038] In specific application scenarios, when spinning molten polymer, it is sieved through a sieve plate 703 to prevent impurities in the molten polymer from clogging the spinneret body 9. At the same time as sieving, the drive motor 707 is started, which drives the rotating disc 708 to rotate. The rotating disc 708 drives the push-pull rod 709 to move the lifting impact block 704 up and down in the slide of the sealed sieve frame 701. This causes the lifting impact block 704 to cause the sieve plate 703 to vibrate up and down, preventing impurities separated during the sieving process from clogging the sieve plate 703 and affecting the sieving efficiency.

[0039] Reference Figure 3 and Figure 5 A cleaning component 8 is provided on the outside of the sealed sieve frame 701, and the cleaning component 8 includes a fixing plate 801. The same guide rod 802 is fixedly connected to the opposite side of the two fixing plates 801, and the same movable slide block 803 is slidably connected to the outside of the two guide rods 802.

[0041] In specific application scenarios, when the spinneret body 9 is not in use, the operator pushes and pulls the push rod 806 to move the movable slide 803 outside the guide rod 802, so that the scraper 804 on the movable slide 803 scrapes away the debris remaining on the surface of the spinneret body 9, while the cleaning brush 805 cleans the surface of the spinneret body 9.

[0042] Reference Figure 6 and Figure 7 Two support frames 3 are fixedly connected to one side of the spinning platform 2 by bolts. The same outer shell 4 is fixedly connected to the opposite side of the two support frames 3. An observation port is opened on one side of the outer shell 4. A transparent observation window 5 is fixedly connected to one side of the observation port. Two movable brackets 1 are fixedly connected to one side of the spinning platform 2.

[0043] Working principle: When the spinning solution or melt enters the cooling cylinder 602 through the melt feed pipe 603, the pump body 618 is activated. The pump body 618 blows the gas purified by the filter head 619 into the hollow rotating frame 607 through the hose 617. Then, the multiple air blowers 609 on the hollow connecting plate 610 blow the gas to cool the spinning solution or melt. At the same time as blowing the gas, the telescopic cylinder 615 is activated. The telescopic cylinder 615 drives the rack 614 to reciprocate inside the guide rail 612, thereby making the spinning solution or melt cool. The rack 614 drives the rotating gear 613 to rotate bidirectionally. The rotating gear 613, in turn, drives the linkage support plate 608 on the hollow rotating frame 607 to rotate bidirectionally, causing the air blower head 609 to rotate bidirectionally and uniformly blow air to cool the textile solution or melt. Simultaneously, as the textile solution or melt moves within the cooling cylinder 602, its feeding speed is controlled by the spiral feed plate 606 to achieve a better cooling effect. The cooling component 6 reduces the temperature of the molten polymer delivered by the spinning pump 604 through the melt pipe. To reduce damage to the spinneret caused by molten polymer, improve the entire spinning process, and thus improve fiber quality, the molten polymer is sieved through a sieve plate 703 during spinning to prevent impurities in the molten polymer from clogging the spinneret body 9. Simultaneously, the drive motor 707 is activated, driving the rotating disc 708 to rotate. This rotating disc 708 drives the push-pull rod 709, which in turn drives the lifting impact block 704 to move up and down within the slide rail of the sealed sieve frame 701. This causes the lifting impact block 704 to vibrate the sieve plate 703, preventing impurities separated during the sieving process from clogging the sieve plate 703 and affecting sieving efficiency. When the spinneret body 9 is not in use, the operator pushes and pulls the push rod 806 to move the movable slide 803 outside the guide rod 802. This allows the scraper 804 on the movable slide 803 to scrape away residual debris from the surface of the spinneret body 9, while the cleaning brush 805 cleans the surface of the spinneret body 9.
