Description

Technical Field

[0001] The invention relates to a spinning device and belongs to the technical field of electrostatic spinning. Background Art

[0002] Free surface electrospinning is a new spinning process that uses a similar spinning principle to bubble electrospinning. It utilizes the electrostatic force provided by a high-voltage electric field to overcome the surface tension of the polymer liquid surface, forming a Taylor cone on the polymer surface, which further forms a jet. The jet is then attenuated into nanofibers under the action of the electric field. Because there are no bubbles involved in this process, it overcomes the shortcomings of bubble electrospinning, such as uncontrollable bubble size, unpredictable bubble burst patterns, and the resulting uneven fiber diameter distribution. It also retains the advantage of high fiber yield of bubble electrospinning. However, when the fiber membrane is required to be a product blended with multiple polymers, the polymer molecular chains often become entangled when two or more polymer solutions are mixed, making the final product less than ideal. Alternatively, the viscosity of the solution after mixing is too high, making it impossible to produce fibers even under high voltage. In the existing scheme, multiple polymer blends are achieved by setting up multiple liquid storage devices or dividing the liquid storage device into multiple areas. However, setting up multiple liquid storage devices increases the volume and cost of the spinning device; using partitions to divide the liquid storage device into zones must ensure that the spinning efficiency is guaranteed while not affecting the quality of the fiber. Summary of the Invention

[0003] The object of the present invention is to provide a spinning device which can realize uniform blending of multiple polymers and has high spinning efficiency.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a spinning device comprising:

[0005] A liquid storage device, wherein the liquid storage device is a prismatic device having a pyramidal groove, wherein an isolation mechanism is provided in the pyramidal groove, and the isolation mechanism separates the pyramidal groove into at least two spinning areas;

[0006] a power supply device, the power supply device being electrically connected to the prismatic device, and when the power supply device supplies power, the spinning solution contained in the prismatic device generates a jet under the action of electrostatics;

[0007] a rotating device, disposed below the prismatic device;

[0008] at least two liquid supply devices, each of the liquid supply devices and the prismatic device being connected to a liquid infusion tube; and

[0009] A receiving device is arranged above the prismatic device to receive the jet.

[0010] Furthermore, the central axis of the prismatic device and the central axis of the pyramidal groove are located on the same axis.

[0011] Furthermore, the prismatic device is a regular prism, and the pyramidal groove is a regular pyramid.

[0012] Furthermore, the height of the isolation mechanism is higher than the liquid level of the spinning solution.

[0013] Furthermore, the isolation mechanism is an insulating baffle.

[0014] Furthermore, the prismatic device is a copper prismatic device.

[0015] The beneficial effects of the present invention are as follows: the present application sets a pyramidal groove to hold the spinning liquid. Since the bottom end of the pyramidal groove is a pointed structure, under the action of the electric field, the pointed structure at the bottom end of the pyramidal groove discharges, making it easy to form a jet in the center of the spinning liquid. At the same time, each side of the pyramidal groove is a slope, and jets can be generated at all points on the slope, thereby improving the spinning efficiency; by setting an isolation mechanism in the groove to divide the groove into multiple spinning areas, and by the uniform rotation of the rotating device, the fibers or microspheres generated in different spinning areas reach various positions of the receiving device to form a uniform mixed fiber or microsphere film, thereby realizing uniform blending of multiple polymers.

[0016] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of a spinning device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0018] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0019] See Figure 1The spinning device shown in one embodiment of the present invention includes a liquid storage device 1, a power supply device 3, a rotating device 4, at least two liquid supply devices (not numbered) and a receiving device 6. The liquid storage device 1 is a prismatic device with a pyramidal groove 11. An isolation mechanism 2 is provided in the pyramidal groove 11. The isolation mechanism 2 divides the pyramidal groove 11 into at least two spinning areas (not numbered). The power supply device 3 is electrically connected to the prismatic device 1. When the power supply device 3 supplies power, the spinning liquid (not shown) contained in the prismatic device 1 generates a jet under the action of static electricity. The rotating device 4 is arranged below the prismatic device 1. Each liquid supply device is connected to the prismatic device 1 by a liquid infusion tube (not numbered). The receiving device 6 is arranged above the prismatic device 1 to receive the jet. Since the bottom end of the pyramidal groove 11 is a pointed structure, under the action of the electric field, the discharge of the pointed structure at the bottom end of the pyramidal groove 11 makes it easy to form a jet in the center of the spinning liquid. At the same time, each side of the pyramidal groove 11 is a slope, and jets can be generated at each slope, thereby improving the spinning efficiency. An isolation mechanism 2 is provided in the pyramidal groove 11 to separate the pyramidal groove 11 into at least two spinning areas, and the uniform rotation of the rotating device 4 drives the prismatic device 1 to rotate, so that the fibers or microspheres generated in at least two spinning areas can reach various positions of the receiving device 6 to form a uniform mixed fiber or microsphere membrane, so that the spinning device can achieve uniform blending of multiple polymers.

[0020] The central axis of the prismatic device 1 and the central axis of the pyramidal groove 11 are coaxial. Specifically, the pyramidal groove 11 is formed by cutting downward from the edge of the upper bottom surface of the prism toward its center point along the height direction of the prism to form a polygonal funnel-shaped structure. The funnel-shaped structure is the pyramidal groove 11.

[0021] The prismatic device 1 is a regular prism, and the pyramidal groove 11 is a regular pyramid. Generally speaking, a regular prism has the characteristics of all side edges being parallel and equal, and the upper and lower bases being congruent polygons with corresponding sides parallel to each other; a regular pyramid has the characteristics of all side edges being equal, the side faces and diagonal faces being isosceles triangles, and the slant heights on each side face being equal. Due to the characteristics of the regular prism and regular pyramid, the inclination angle and size of each slant face on the pyramidal groove 11 are the same. When the power supply device 3 supplies power, a uniformly distributed charge is generated on each slant face of the pyramidal groove 11. Under the action of the electric field, the amount of fibers or microspheres generated on each slant face is roughly the same. Through the uniform rotation of the rotating device 4, the fibers or microspheres generated on each slant face are evenly dispersed and mixed together, and then received by the receiving device 6, forming a fiber or microsphere film with multiple polymers that are independent and evenly mixed.

[0022] In this embodiment, the prismatic device 1 is a regular hexagonal prism, and the pyramidal groove 11 is a regular hexagonal pyramid. The number of edges of the pyramidal groove 11 is the same as that of the prismatic device 1, which makes the manufacturing process of the pyramidal groove 11 more convenient. Of course, in other embodiments, the number of edges of the prismatic device 1 and the pyramidal groove 11 can be other numbers, specifically a regular square prism, a regular pentagonal prism or a regular octagonal prism, etc. The number of edges of the prismatic device 1 and the pyramidal groove 11 can be adjusted according to the required number of spinning areas.

[0023] The height of the isolation mechanism 2 is higher than the liquid level of the spinning solution to prevent the spinning solutions in different spinning areas from overflowing and mixing together, which would affect the spinning effect. The isolation mechanism 2 is an insulating baffle. When the power supply device 3 supplies power, since the insulating baffle 2 is non-conductive, the insulating baffle 2 will not be affected by static electricity to produce fibers, so that the fibers produced by the two adjacent spinning areas will not interfere with each other, thereby improving the spinning efficiency. In this embodiment, the insulating baffle 2 is a polymer baffle. The polymer baffle 2 adopts existing technology and is not described in detail here. In this embodiment, the polymer baffle 2 is arranged on the plane where the central axis of the bottom surface of the regular hexagonal pyramid groove 11 is located to separate the regular hexagonal pyramid groove 11 into two areas of equal size. The two areas are respectively named the first spinning area 112 and the second spinning area 111.

[0024] In this embodiment, the prismatic device 1 is made of copper. Copper metal has high conductivity, corrosion resistance, and is easily processed and formed. Furthermore, its low cost reduces the manufacturing cost of the spinning device. Of course, in other embodiments, the prismatic device 1 may be made of other materials, specifically silver, as long as the required conductivity and device strength are met during spinning.

[0025] Taking this embodiment as an example, there are two spinning zones, and therefore two liquid supply devices are provided. The two liquid supply devices are designated as a first liquid supply device 51 and a second liquid supply device 52. The first liquid supply device 51 is connected to the first spinning zone 112 via a first liquid infusion tube 53, and the second liquid supply device 52 is connected to the second spinning zone 111 via a second liquid infusion tube 54. The first zone 112 is provided with a first opening 55 that mates with the first liquid infusion tube 53, and the second zone 111 is provided with a second opening 56 that mates with the second liquid infusion tube 54.

[0026] The specific operation process of the spinning device of this embodiment is as follows: a first spinning solution (not shown) is added to the first liquid supply device 51, and a second spinning solution (not shown) is added to the second liquid supply device 53, so that the first spinning solution and the second spinning solution are respectively filled in the first spinning area 112 and the second spinning area 111. The switch of the power supply device 4 is turned on to supply power. An electric field is simultaneously formed between the first spinning area 112 and the second spinning area 111 and the receiving device 6. Under the action of electrostatics, the first spinning solution and the second spinning solution form a jet inside and at the edge of the regular hexagonal pyramid groove 11. The jet evaporates, swings, and thins during the process of reaching the receiving device 6 from the regular hexagonal pyramid groove 11. As the rotating device 4 rotates, the fibers or microspheres generated in the first spinning area 112 and the second spinning area 111 can reach various positions of the receiving device 6, thereby forming a uniform mixed fiber or microsphere film.

[0027] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
