Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic fiber spinning, and more specifically, to a centrifugal spinning disk. Background Art
[0002] Plastic fibers refer to linear materials with a diameter on the nanoscale and a relatively large length-to-diameter ratio. Due to their physical and chemical properties, they are widely used in fields such as chemical engineering and medicine. For example, implanting plastic fibers on the surface of a fabric can form a stable gas film to make a double-hydrophobic interfacial fabric, which can be both waterproof and oil- and stain-proof; high-grade protective clothing made of plastic fibers has porous and membranous fabrics, which can not only allow air to pass through and have breathability, but also block wind and filter fine particles, have a barrier effect on aerosols, and can prevent biochemical weapons and toxic substances.
[0003] There are many methods for manufacturing plastic fibers, such as stretching method, template synthesis, self-assembly, microphase separation, electrospinning, etc. Among them, the electrospinning method is widely used due to its advantages such as simple operation, wide application range, and relatively high production efficiency. However, a high voltage needs to be applied during the process of preparing plastic fibers by electrospinning, which is not only dangerous to operate but also cannot be mass-produced. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that the wire drawing efficiency of the centrifugal spinning head in the prior art is low and the wire drawing distance is short. To overcome the above defects of the prior art, the utility model provides a centrifugal spinning disk.
[0005] The utility model provides a centrifugal spinning disk, which includes a disk body. A connecting part, a liquid containing groove, and a wire drawing groove are arranged on the disk body. The connecting part is arranged at the center of the disk body and is used for connecting the output end of a driver. The liquid containing groove is arranged outside the connecting part and is used for containing spinning liquid. The number of the wire drawing grooves is multiple and they are all communicated with the liquid containing groove. The multiple wire drawing grooves are circumferentially distributed outside the liquid containing groove. The multiple wire drawing grooves radially extend to the edge of the disk body. The wire drawing grooves are gradually inclined upward from inside to outside in the radial direction.
[0006] Compared with the prior art, a centrifugal spinning disk of the present application has the following advantages: by arranging multiple wire drawing grooves circumferentially distributed outside the liquid containing groove, when the spinning disk rotates at a high speed, the multiple wire drawing grooves draw wires synchronously, improving the wire drawing efficiency of spinning; at the same time, the wire drawing grooves are gradually inclined upward from inside to outside in the radial direction, playing a guiding role before the formation of plastic fiber spinning, avoiding loss, and increasing the wire drawing distance, which is beneficial to collecting the silk thread.
[0007] In a possible implementation manner, a plurality of annular protrusions are arranged in the liquid containing groove. The plurality of annular protrusions are arranged radially, and the heights of the plurality of annular protrusions decrease one by one from inside to outside.
[0008] Compared with the prior art, adopting the above technical solution can, through the setting of multiple annular protrusions with gradually decreasing height from inside to outside, prevent the spinning solution in the liquid storage tank from flowing into the connecting part of the disk body when the device is stationary, reducing the loss of the spinning solution.
[0009] In a possible implementation manner, each of the annular protrusions is gradually inclined upward from inside to outside in the radial direction.
[0010] Compared with the prior art, adopting the above technical solution can, through the setting of each annular protrusion gradually inclined upward from inside to outside in the radial direction, facilitate the smooth introduction of the spinning solution into the wire outlet groove.
[0011] In a possible implementation manner, the inclination angle of the annular protrusion is 0 - 90 degrees.
[0012] Compared with the prior art, adopting the above technical solution can, through the setting of the inclination angle of the annular protrusion being 0 - 90 degrees, within this range, the spinning solution can smoothly flow into the wire outlet groove.
[0013] In a possible implementation manner, the inclination angle of the wire outlet groove is 0 - 90 degrees.
[0014] Compared with the prior art, adopting the above technical solution can, through the setting of the inclination angle of the wire outlet groove being 0 - 90 degrees, increase the wire outlet distance after centrifugal throwing.
[0015] In a possible implementation manner, multiple wire outlet grooves are arranged at equal intervals in the circumferential direction.
[0016] Compared with the prior art, adopting the above technical solution can improve the uniformity and quality of wire outlet of the wire discharging disk. Description of the Drawings

[0025] The following further elaborates on this application in detail with reference to the drawings and specific embodiments.
[0026] See Figures 1 to 3 , an embodiment of this application discloses a centrifugal spinning disk, including a disk body 1. A connecting portion 2, a liquid storage groove 3 and a wire outlet groove 4 are provided on the disk body 1. The connecting portion 2 is arranged at the center of the disk body 1 and is used to connect the output end of a driver. The liquid storage groove 3 is arranged outside the connecting portion 2 and is used to store spinning liquid. The number of the wire outlet grooves 4 is multiple and they are all communicated with the liquid storage groove 3. The multiple wire outlet grooves 4 are circumferentially distributed outside the liquid storage groove 3. The multiple wire outlet grooves 4 extend radially to the edge of the disk body 1. The wire outlet groove 4 is gradually inclined upward from inside to outside in the radial direction.
[0027] Specifically, the number of the wire outlet grooves 4 is twenty-four, and the twenty-four wire outlet grooves 4 are evenly spaced and circumferentially distributed.
[0028] As can be known above, when the spinning disk rotates at a high speed, the twenty-four wire outlet grooves 4 discharge wires synchronously, improving the wire discharging efficiency of spinning; at the same time, the wire outlet groove 4 is gradually inclined upward from inside to outside in the radial direction, playing a guiding role before the formation of plastic fiber spinning, avoiding losses, and increasing the wire discharging distance, which is beneficial to collecting the silk thread.
[0029] In this embodiment, three annular protrusions 31 are provided in the solution tank 3. The three annular protrusions 31 are arranged radially, and the heights of the three annular protrusions 31 decrease one by one from the inside to the outside. Thus, when the spinning disk is stationary, the spinning solution in the solution tank 3 will not flow into the connecting portion 2 of the disk body 1, reducing the loss of the spinning solution. Each annular protrusion 31 is gradually inclined upward from the inside to the outside in the radial direction, facilitating the smooth introduction of the spinning solution into the wire outlet groove 4. The inclination angle of the annular protrusion 31 is 20 degrees.
[0030] In this embodiment, the inclination angle of the wire outlet groove 4 is 10 degrees.
