Description

Technical Field

[0001] This invention relates to an improvement in spinneret technology, belonging to the textile field, and particularly to a conical spinneret system for centrifugal spinning. Background Technology

[0002] Centrifugal spinning refers to a method in which certain polymer melts are spun out of fine orifices by centrifugal and shear forces generated by a high-speed rotating device to form fibers. The resulting fibers vary in length and diameter and can be directly laid into felt sheets. It is mainly used to spin glass fibers, phenolic resins, and general-purpose pitch carbon fibers. The process conditions vary depending on the polymer used. Air nozzles at various angles can also be set outside the spinneret to draw and solidify the spun fibers. However, in existing centrifugal spinning, the spun fibers splash everywhere during spinning, which is not convenient to collect.

[0003] Chinese patent application CN201910526732.7, filed on June 18, 2019, discloses a centrifugal electrospinning nozzle, comprising: an inlet pipe, a transition liquid storage container, and a rotating nozzle. The inlet pipe and the transition liquid storage container are connected, and the rotating nozzle is located at the bottom of the transition liquid storage container. The bottom of the transition liquid storage container has an outlet, which is coaxially arranged with the rotating nozzle. By setting up the transition liquid storage container, the solution can be buffered, thereby ensuring a continuous and stable supply of solution to the rotating nozzle. Importantly, by aligning the outlet of the transition liquid storage container with the rotating nozzle, the solution entering the rotating nozzle remains concentric, thus improving the spinning quality of the centrifugal electrospinning nozzle. However, the above technology does not solve the problem of spun fibers splashing everywhere during centrifugal spinning, making collection inconvenient.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

The spinneret has a recessed portion on its left side that is recessed toward the feed container, and the outer sleeve has multiple annularly distributed air holes on its side at the large diameter end. The top of the upper outer sleeve is connected to the bottom of the upper hollow column, the top of the upper hollow column is connected to the bottom of the top plate, the bottom of the lower outer sleeve is connected to the top of the lower hollow column, the bottom of the lower hollow column is inserted into the top of the stabilizer, the upper hollow column is connected to the upper outer sleeve, and the cavity of the lower outer sleeve, the lower hollow column and the stabilizer are sequentially connected to each other. The bottom of the feed container is connected to the top of two support rods, the bottom of the two support rods is inserted into the top of the stabilizing seat, the bottom of the stabilizing seat is connected to the bottom of the top of the base plate, and the two support rods are arranged axially side by side. A collection section is provided between the base plate and the stabilizing seat, and the collection section is coaxially arranged with the material container. A gear is fitted on the side of the container between two support rods. A motor cover is installed on the bottom of the top plate on the side of the upper hollow column. A motor is installed inside the motor cover. The output shaft of the motor is connected to two gears. The side of the two gears meshes with the inner side of one end of the belt. The other end of the belt passes through the motor cover and meshes with the two gears. The motor and the container are connected by belt drive.

[0007] Each support rod is equipped with a stabilizing ring at the top, and a material container is fitted inside the two stabilizing rings. The two stabilizing rings are located on the left and right sides of a gear. The stabilizing ring is rotated in conjunction with the feed container.

[0008] All of the spinnerets are conical in orthographic projection, and the diameter of the spinnerets increases from the tip to the arc end.

[0009] There is a spinning zone between the spinneret and the spinneret disc.

[0010] The inner wall of the outer sleeve is provided with annularly distributed inclined guide holes; The spinneret has an edge area located on the outer ring of the recessed part, which is a V-shaped area that is wider at the top and narrower at the bottom. The diameter of the annular region formed by all the spinnerets is smaller than the diameter of the annular region formed by all the guide holes, and the diameter of the annular region formed by all the guide holes is smaller than the diameter of the annular region formed by all the air holes.

[0011] The lower outer sleeve and the upper outer sleeve have the same structure and are arranged symmetrically. The upper hollow column and the lower hollow column have the same structure, size, and height; The inclination of the lower outer sleeve is the same as that of the spinneret, and the center of the lower outer sleeve and the center of the spinneret are on the same horizontal plane.

[0012] The length of the lower outer sleeve is greater than the length of the spinneret, and the guide hole is located on the right side of the spinneret; The guide hole is inclined toward the center of the spinneret.

[0013] All the spinnerets, air holes, and guide holes are distributed in an interwoven manner; The air holes are arranged parallel to the axis of the spinneret.

[0014] The stabilizer is provided with an air storage chamber, which is connected to the lower hollow column. There is a gap between the lower hollow column, the two support rods and the bottom of the gas storage chamber, and the lower hollow column and the two support rods move longitudinally along the gas storage chamber.

[0015] The collecting section reciprocates along the horizontal direction of the stabilizing seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In a conical spinneret system for centrifugal spinning, the tops of two support rods are connected to the bottom of a feed container, and the right side of the feed container is connected to the left side of a conical spinneret. The inner ring of the spinneret has a plurality of evenly distributed spinneret holes. The feed container, spinneret, and spinneret holes are sequentially connected. In application, the material in the feed container is thrown towards the periphery of the spinneret. Upon reaching the vicinity of the four corners of the spinneret, it passes through the spinneret area and is ejected along the spinneret holes to form spun yarn. The design of the spinneret holes limits the direction and range of the spun yarn ejection, preventing it from splashing everywhere and resulting in a smoother yarn. Airflow from the vents in the lower outer sleeve further organizes and guides the ejected yarn, making it easier to collect. Therefore, this design facilitates yarn collection and produces smooth yarn.

[0017] 2. In a conical spinneret system for centrifugal spinning, the spinneret disc has an edge region located on the outer ring of the recessed portion. This edge region is a V-shaped area, wider at the top and narrower at the bottom. The diameter of the annular region formed by all the spinneret holes is smaller than the diameter of the annular region formed by all the guide holes, and the diameter of the annular region formed by all the guide holes is smaller than the diameter of the annular region formed by all the air holes. In application, the recessed portion design allows the spinneret to be ejected along the edge region after passing through the spinneret holes, thus limiting the position of the ejected spinneret. The spinneret hole design further limits the direction and range of the ejected spinneret, preventing the spinneret from flowing directly downwards along the spinneret disc while being ejected from the feed container. Therefore, this design allows for continuous and stable spinning.

[0018] 3. In the conical spinneret system for centrifugal spinning of this invention, the inner wall of the outer sleeve is provided with annularly distributed inclined guide holes. The guide holes are inclined towards the center of the spinneret, and all spinneret holes, air holes, and guide holes are staggered. The air holes are arranged parallel to the axis of the spinneret, and the guide holes are inclined along the spinning area of ​​the spinneret, spraying inclined gas to restrict and guide the spinning. The air holes are arranged parallel to the axis of the spinneret, and the sprayed gas can confine the spun yarn within the transverse area of ​​the spinneret, avoiding the problem of spun yarn scattering everywhere and making it easier to collect. Therefore, this design provides a stable spinning spray area and more convenient collection. Attached Figure Description

A motor 12 is installed inside the motor cover 11. The output shaft of the motor 12 is connected to two gears 13. The side of the two gears 13 meshes with the inner side of one end of the belt 10. The other end of the belt 10 passes through the motor cover 11 and meshes with the two gears 13. The motor 12 and the feed container 6 are connected by the belt 10.

[0035] Each support rod 4 is equipped with a stabilizing ring 5 at its top. A feeder 6 is fitted inside the two stabilizing rings 5. The two stabilizing rings 5 ​​are located on the left and right sides of a gear 7. The stabilizing ring 5 and the feed container 6 are rotated together.

[0036] All of the spinnerets 81 have a tapered orthographic projection, and the diameter of the spinnerets 81 increases from the tip 83 to the arc end 84.

[0037] There is a spinneret zone 82 between the spinneret hole 81 and the spinneret disc 8.

[0038] The inner wall of the outer sleeve 9 is provided with annularly distributed inclined guide holes 92; The spinneret 8 has an edge region 85 located on the outer ring of the recess 86. The edge region 85 is a V-shaped area that is wider at the top and narrower at the bottom. The diameter of the annular region formed by all the spinnerets 81 is smaller than the diameter of the annular region formed by all the guide holes 92, and the diameter of the annular region formed by all the guide holes 92 is smaller than the diameter of the annular region formed by all the air holes 91.

[0039] The lower outer sleeve 9 and the upper outer sleeve 17 have the same structure and are arranged symmetrically. The upper hollow column 15 and the lower hollow column 14 have the same structure, size and height; The inclination of the lower outer sleeve 9 is the same as the inclination of the spinneret 8, and the center of the lower outer sleeve 9 and the center of the spinneret 8 are on the same horizontal plane.

[0041] All the spinneret holes 81, air holes 91, and guide holes 92 are distributed in an alternating pattern. The air hole 91 is arranged parallel to the axis of the spinneret 8.

[0042] The stable base 3 is provided with an air storage cavity 31, which is connected to the lower hollow column 14.

[0043] The collecting section 16 reciprocates along the horizontal direction of the stabilizing seat 3.

[0044] The principle of this invention is explained as follows: During centrifugation, the motor 12 drives the feed container 6 to rotate. The molten material or liquid in the feed container 6 is thrown towards the periphery of the spinneret 8. When it reaches the vicinity of the four corners of the spinneret 8, it is ejected through the spinneret holes 81 to form spun yarn. The spinneret holes 81 restrict the direction of the spun yarn ejection. At the same time, the air holes 91 and guide holes 92 in the lower outer sleeve 9 eject airflow to organize the ejected spun yarn, limit its ejection direction and position, and ensure that the ejected spun yarn falls onto the collection part 16. In addition, the rotation state of the feed container 6 will affect the shape of the ejected spun yarn. The spiral hollow structure of the feed container 6 makes it easy to collect.

[0045] Example 1: A conical spinneret system for centrifugal spinning, comprising a feed container 6, a spinneret disc 8, a lower outer sleeve 9, and an upper outer sleeve 17; the right side of the feed container 6 is connected to the left side of the conical spinneret disc 8, and the inner ring of the spinneret disc 8 has a plurality of uniformly distributed spinneret holes 81; the feed container 6, the spinneret disc 8, and the spinneret holes 81 are sequentially connected; the lower outer sleeve 9 and the upper outer sleeve 17 are respectively fitted around the side of the spinneret disc 8, with the top of the lower outer sleeve 9 fitting snugly against the bottom of the upper outer sleeve 17; the left side of the spinneret disc 8 has a recessed portion 86 that is recessed towards the feed container 6, and the side of the large-diameter end of the outer sleeve 9 has an opening... Multiple annularly distributed air holes 91 are provided; the top of the upper outer sleeve 17 is connected to the bottom of the upper hollow column 15, the top of the upper hollow column 15 is connected to the bottom of the top plate 2, the bottom of the lower outer sleeve 9 is connected to the top of the lower hollow column 14, the bottom of the lower hollow column 14 is inserted into the top of the stabilizing seat 3, the upper hollow column 15 is connected to the upper outer sleeve 17, and the cavity 93 of the lower outer sleeve 9, the lower hollow column 14 and the stabilizing seat 3 are sequentially connected to each other; the bottom of the feed container 6 is connected to the top of the two support rods 4, the bottom of the two support rods 4 is inserted into the top of the stabilizing seat 3, the bottom of the stabilizing seat 3 is connected to the bottom of the top of the bottom plate 1, and the two support rods 4 are arranged axially side by side; A collecting part 16 is provided between the base plate 1 and the stabilizing seat 3, and the collecting part 16 is coaxially arranged with the material container 6; a gear 7 is sleeved on the side of the material container 6 between two support rods 4; a motor cover 11 is installed on the side of the upper hollow column 15 at the bottom of the top plate 2; a motor 12 is installed inside the motor cover 11; the output shaft of the motor 12 is connected to two gears 13; the side of the two gears 13 meshes with the inner side of one end of the belt 10; the other end of the belt 10 passes through the motor cover 11 and meshes with the two gears 13; the motor 12 and the material container 6 are connected by the belt 10.

[0046] When applying: The motor 12 is started, and the motor 12 drives the two gears 13 to rotate. The belt 10 drives the gear 7 to rotate, which in turn drives the material container 6 inside the gear 7 to rotate. The molten material or liquid in the material container 6 is thrown to the periphery of the spinneret 8. When it reaches the vicinity of the four corners of the spinneret 8, it passes through the spinneret zone 82 and is ejected along the spinneret hole 81 to form spun yarn. At the same time, the air vents 91 in the lower outer sleeve 9 eject airflow to sort the ejected spun yarn and ensure that the ejected spun yarn falls onto the collection section 16.

[0047] Example 2: Example 2 is basically the same as Example 1, except that: A conical spinneret system for centrifugal spinning, wherein all the spinnerets 81 are conical in orthographic projection, and the diameter of the spinnerets 81 increases from the tip 83 to the arc end 84; there is a spinneret zone 82 between the spinnerets 81 and the spinneret 8; the inner wall of the outer sleeve 9 is provided with annularly distributed inclined guide holes 92; an edge zone 85 is provided on the outer ring of the recess 86 in the spinneret 8, and the edge zone 85 is a V-shaped area that is wider at the top and narrower at the bottom.

[0048] When applying: The recessed portion 86 is designed so that the spinneret is thrown out along the edge region 85 after passing through the spinneret hole 81, thus limiting the position of the spinning ejection. The spinneret hole 81 is positioned close to the edge region 85 so that the feed container 6 can still perform normal spinning even when there is a small amount of filament liquid, ensuring that the continuity of the spinning is not affected. The front-facing and rear-facing outlet design of the spinneret hole 81 limits the direction and range of the spinning ejection, preventing the filament from flowing directly down the spinneret 8 while being thrown out of the feed container 6, thereby affecting the normal spinning operation.

[0049] Example 3: Example 3 is basically the same as Example 1, except that: A conical spinneret system for centrifugal spinning includes an outer sleeve 9 with annularly distributed inclined guide holes 92 on its inner wall; an edge region 85, which is a V-shaped area wider at the top and narrower at the bottom, is located on the outer ring of the recessed portion 86 inside the spinneret 8; the diameter of the annular region formed by all the spinnerets 81 is smaller than the diameter of the annular region formed by all the guide holes 92, and the diameter of the annular region formed by all the guide holes 92 is smaller than the diameter of the annular region formed by all the air holes 91; the lower outer sleeve 9 has the same structure as the upper outer sleeve 17 and is symmetrically arranged; the inclination of the lower outer sleeve 9 is the same as the inclination of the spinneret 8, and the centers of the lower outer sleeve 9 and the spinneret 8 are on the same horizontal plane; the length of the lower outer sleeve 9 is greater than the length of the spinneret 8, and the guide holes 92 are located on the right side of the spinneret 8; the guide holes 92 are inclined towards the center of the spinneret 8; all the spinnerets 81, air holes 91, and guide holes 92 are staggered, and the air holes 91 are parallel to the axis of the spinneret 8.

[0050] When applying: The air hole 91 is set parallel to the axis of the spinneret 8. The ejected gas can confine the spinning to the transverse area of ​​the spinneret 8. The guide hole 92 is inclined along the spinning area of ​​the spinneret 8 and ejects inclined gas, which further restricts and guides the spinning, so that the spinning range is kept within the axial area of ​​the spinneret 8, avoiding the problem of the spinning scattering everywhere and making it easier to collect.

[0051] Example 4: Example 4 is basically the same as Example 1, except that: See Figure 13 A conical spinneret system for centrifugal spinning, wherein the feed container 6 and the spinneret 8 are arranged with the spinning direction facing downward, the lower outer sleeve 9 and the upper outer sleeve 17 are respectively arranged on the left and right sides of the spinneret 8, and the lower hollow column 14 and the upper hollow column 15 are respectively arranged on the corresponding lower outer sleeve 9 and upper outer sleeve 17.

[0052] In application: The feeder 6 rotates, and the material in the feeder 6 is thrown downwards. The spinning yarn is thrown along the spinneret hole 81 to the lower periphery of the spinneret 8. At this time, the air holes 91 in the lower outer sleeve 9 and the upper outer sleeve 17 eject airflow to sort out the ejected spinning yarn and ensure that the ejected spinning yarn falls into the collection section 16 area directly below the feeder 6 for collection.
