Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] In the related art, the spinning module often outputs the spinning solution through a needle assembly, wherein the needle of the needle assembly is usually designed as a straight cylinder, but this arrangement cannot make the needle assembly have a large extrusion force when outputting the spinning solution.

[0048] The present invention provides a multi-needle spinning module 10 .

[0049] See also Figures 5 to 7 In one embodiment of the present invention, the multi-needle spinning module 10 includes an infusion assembly 12 and a needle assembly 11, wherein the needle assembly 11 is provided with a plurality of needle assemblies 11, and the plurality of needle assemblies 11 are arranged in an array in the infusion assembly 12 and are all connected to the infusion assembly 12;

[0050] A liquid outlet channel with two ends connected is formed in the needle 111 of the needle assembly 11, and the needle 111 includes:

[0051] A barrel portion 1111, one end of which is provided with a liquid inlet connected to the liquid outlet channel for receiving the spinning solution; and

[0052] The cone portion 1112 has one end connected to the barrel portion 1111 and the other end provided with a liquid outlet connected to the liquid outlet channel for extruding the spinning liquid. The cross-sectional area of ​​the cone portion 1112 gradually decreases in a direction away from the barrel portion 1111.

[0053] In some embodiments, the infusion assembly 12 may include only one infusion pipeline, and the multiple needles 111 may be arranged in sequence along the length direction of the infusion pipeline, but not limited to being arranged in intervals; the infusion pipeline may be used for the liquid supply mechanism 200 of the external spinning device 1000, and is used to receive the spinning solution provided by the liquid supply mechanism 200 to the multi-needle spinning module, so that the spinning solution is diverted to the multiple needle assemblies 11 through the infusion pipeline, so that the spinning solution is output to the outside through the needles 111 of the multiple needle assemblies 11 and a jet is formed, thereby performing electrospinning. The jets at the multiple needle assemblies 11 may have the same injection rate and frequency.

[0054] Of course, the technical solution of the present invention is not limited to this. In some embodiments, the infusion assembly may also be composed of multiple infusion pipelines as in the following embodiments, and the multiple infusion pipelines include a first infusion pipeline 121 as a main pipeline and a second infusion pipeline 122 as a branch pipeline. The multiple needles 111 may be, but are not limited to, arranged in sequence along the length direction of the branch pipeline. The main pipeline is used to connect multiple branch pipelines and can be used for the liquid supply mechanism 200 of the external spinning equipment 1000, thereby realizing the liquid supply function of several needle assemblies 11 through the main pipeline, and further realizing the liquid supply function of multiple needle assemblies through the branch pipeline.

[0055] By providing an infusion component 12, and installing a plurality of needle components 11 based on the infusion component 12, on the one hand, the liquid supply function of the multi-needle spinning module 10 to the plurality of needle components 11 can be realized through the infusion component, and on the other hand, the modular design of the multi-needle spinning module 10 can be facilitated by combining the infusion component 12 and the plurality of needle components 11 into one. Among them, the infusion pipeline in the aforementioned embodiment can be configured to be composed of a pipe structure, and a hollow space for transmitting the spinning liquid is formed in the pipe structure, and the plurality of pipe structures can be interconnected through pipe joints or other types of connecting structures; the infusion pipeline in the aforementioned embodiment can also communicate through other structures, for example, a hollow cavity is formed in an integrally formed entity structure, so as to form an infusion pipeline through the hollow cavity. The specific implementation method can be set according to actual needs and is not limited here.

[0056] It can be understood that the needle 111 of the technical solution of the present invention is formed with a liquid outlet channel with two ends connected. The needle 111 includes a barrel portion 1111 and a cone portion 1112. One end of the barrel portion 1111 is provided with a liquid inlet connected to the liquid outlet channel for receiving the spinning solution; one end of the cone portion 1112 is connected to the barrel portion 1111, and the other end is provided with a liquid outlet connected to the liquid outlet channel for extruding the spinning solution. Among them, by making the needle 111 of the needle assembly 11 have a cone portion 1112, and making the cross-sectional area of ​​the cone portion 1112 gradually decrease in the direction away from the barrel portion 1111, the needle 111 can exert a large extrusion force on the spinning solution when the spinning solution is output from the liquid outlet, thereby achieving the technical effect of fine and dense silk output from the needle assembly 11.

[0057] It should be noted that the multiple needle assemblies 11 are arranged in a geometric array. For example, in some embodiments, the multiple needle assemblies 11 can be arranged in a rectangular unit array, and the rectangular units are arranged equidistantly, and two adjacent rectangular units can share a side, and each rectangular unit is provided with a needle assembly 11 at its vertex. The rectangular unit can be square, and its side length can be set to 20 mm.

[0058] Alternatively, in some embodiments, the plurality of needle assemblies 11 may also be in an isosceles triangle unit array, wherein the isosceles triangle units are arranged equidistantly, two adjacent isosceles triangle units may share a vertex, and each isosceles triangle unit is provided with a needle assembly 11 at its vertex. The length of the base of the isosceles triangle unit may be set to 20 mm, and the height of the base may be set to 20 mm.

[0059] Alternatively, in some embodiments, the plurality of needle assemblies 11 may also be in an isosceles trapezoidal unit array, wherein the isosceles trapezoidal units are arranged at equal distances, and two adjacent isosceles trapezoidal units may share a vertex located on the bottom edge, and each isosceles trapezoidal unit is provided with a needle assembly 11 at its vertex position. The upper and lower bases of the isosceles trapezoidal unit may be set to 20 mm and 30 mm, respectively, and the height may be set to 20 mm.

[0060] It can be understood that by arranging the multiple needle assemblies 11 in a geometric array of a specific shape, it is beneficial for the multi-needle spinning module 10 to obtain a relatively high electric field strength under the condition of ensuring a certain jet density. Of course, the technical solution of the present invention is not limited to this. In some embodiments, the multiple needle assemblies 11 can also be arranged in geometric units of other shapes besides rectangles, triangles and trapezoids, which are not limited here.

[0061] Further, in an embodiment of the present invention, it is defined that a plurality of needle assemblies 11 are arranged in a geometric array in the xy plane, and the multi-needle spinning module 10 also includes an auxiliary electrode. In a feasible embodiment, a plurality of needle assemblies 11 are arranged in the x direction, and two groups of auxiliary electrodes are provided. The two groups of auxiliary electrodes can be arranged on both sides of the array of needle assemblies 11 along the x direction, and each group of auxiliary electrodes includes two auxiliary electrodes arranged side by side. In addition, the auxiliary electrode is a positive voltage auxiliary electrode, so that the electric field strength around the tip of the needle 111 of the needle assembly 11 during electrostatic spinning can be weakened by introducing a positive voltage auxiliary electrode. Alternatively, in another feasible embodiment, a plurality of needle assemblies 11 are arranged in the x direction, and two auxiliary electrodes are provided. The two auxiliary electrodes can be arranged on both sides of the array of the needle assembly 11 along the y direction, and are both located at the center of the side of the array of the needle assembly 11. In addition, the auxiliary electrode is a grounded auxiliary electrode, so that the electric field strength around the tip of the needle 111 of the needle assembly 11 during electrostatic spinning can be increased by introducing a grounded auxiliary electrode. It is understandable that the multi-needle spinning module 10 can generate uniform and stable jet vibration and electric field distribution during electrospinning by setting auxiliary electrodes, and further produce finer and more uniform polymer nanofibers through more uniform electric field distribution.
