[0047] In related technologies, spinning modules often output spinning solution through needle assemblies. The needles in these needle assemblies are typically designed as straight cylinders, but this configuration prevents the needle assembly from generating significant extrusion force when outputting the spinning solution.

[0048] This utility model proposes a multi-needle spinning module 10.

[0049] Please see 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. Multiple needle assemblies 11 are provided, and the multiple needle assemblies 11 are arranged in an array on the infusion assembly 12 and are all connected to the infusion assembly 12.

[0050] The needle assembly 11 has a liquid outlet channel extending through both ends within the needle 111, and the needle 111 includes:

[0051] The cylindrical body 1111 has an inlet at one end that connects to the liquid outlet channel for receiving spinning solution; and

[0052] The cone portion 1112 has one end connected to the cylindrical portion 1111 and the other end has an outlet that communicates with the liquid outlet channel for extruding spinning solution. The cross-sectional area of ​​the cone portion 1112 is gradually reduced in the direction away from the cylindrical portion 1111.

[0053] In some embodiments, the infusion assembly 12 may include only one infusion line, and multiple needles 111 may be arranged sequentially at intervals along the length of the infusion line, but are not limited to this one. The infusion line may be used to connect to the supply mechanism 200 of the external spinning device 1000 to receive the spinning solution provided by the supply mechanism 200 to the multi-needle spinning module, so that the spinning solution is distributed through the infusion line to the multiple needle assemblies 11, and the spinning solution is output outward through the needles 111 of the multiple needle assemblies 11 to form a jet, thereby performing electrospinning. The jets at the multiple needle assemblies 11 may have the same jetting rate and frequency.

[0054] Of course, the technical solution of this utility model is not limited to this. In some embodiments, the infusion assembly may also be composed of multiple infusion lines as in the following embodiment. The multiple infusion lines include a first infusion line 121 as a main line and a second infusion line 122 as a branch line. Multiple needles 111 may be arranged sequentially at intervals along the length direction of the branch line, but not limited to this. The main line is used to connect multiple branch lines and can be used to connect to the liquid supply mechanism 200 of the external spinning equipment 1000. Thus, the liquid supply function of several needle assembly 11 can be realized through the main line, and the liquid supply function of multiple needle assembly can be realized further through the branch lines.

[0055] By setting up an infusion assembly 12 and installing multiple needle assemblies 11 based on the infusion assembly 12, on the one hand, the infusion assembly can realize the function of supplying liquid to multiple needle assemblies 11 by the multi-needle spinning module 10; on the other hand, by combining the infusion assembly 12 and multiple needle assemblies 11 into one unit, it provides convenience for the modular design of the multi-needle spinning module 10. In the aforementioned embodiment, the infusion pipeline can be configured as a pipe structure with a hollow space formed within it for transmitting spinning liquid. Multiple pipe structures can be interconnected through pipe joints or other types of connection structures. Alternatively, the infusion pipeline in the aforementioned embodiment can be connected through other structures, for example, forming a hollow cavity in a one-piece solid structure to form the infusion pipeline. Specific implementation methods can be set according to actual needs and are not limited here.

[0056] Understandably, the needle 111 of this utility model has a liquid outlet channel extending through both ends. The needle 111 includes a cylindrical portion 1111 and a conical portion 1112. One end of the cylindrical portion 1111 has an inlet connected to the liquid outlet channel for receiving spinning liquid. One end of the conical portion 1112 is connected to the cylindrical portion 1111, and the other end has an outlet connected to the liquid outlet channel for extruding spinning liquid. By making the needle 111 of the needle assembly 11 have a conical portion 1112, and by making the cross-sectional area of ​​the conical portion 1112 gradually decrease in the direction away from the cylindrical portion 1111, a larger extrusion force can be applied to the spinning liquid when the needle 111 outputs spinning liquid outward from the outlet, thereby achieving the technical effect of fine yarn output from the needle assembly 11.

[0057] It should be noted that the multiple needle components 11 are arranged in a geometric array. For example, in some embodiments, the multiple needle components 11 can be arranged in a rectangular unit array, with several rectangular units arranged at equal intervals, and adjacent rectangular units can share one side. Each rectangular unit has a needle component 11 at its vertex. The rectangular unit can be square, and its side length can be set to 20mm.

[0058] Alternatively, in some embodiments, the multiple needle components 11 may be arranged in an array of isosceles triangular units, with the isosceles triangular units equidistant from each other. Adjacent isosceles triangular units may share a vertex, and each isosceles triangular unit has a needle component 11 at its vertex. The base side length of the isosceles triangular unit may be set to 20mm, and the height of its base side may be set to 20mm.

[0059] Alternatively, in some embodiments, the multiple needle components 11 may be arranged in an array of isosceles trapezoidal units, with the isosceles trapezoidal units equidistant from each other. Adjacent isosceles trapezoidal units may share a vertex located on the base, and each isosceles trapezoidal unit has a needle component 11 at its vertex. The upper and lower bases of the isosceles trapezoidal units may be set to 20mm and 30mm respectively, and the height may be set to 20mm.

[0060] It is understood that by arranging multiple needle components 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 while ensuring a certain jet density. Of course, the technical solution of this utility model is not limited to this. In some embodiments, the multiple needle components 11 may also be arranged in geometric units of other shapes than rectangles, triangles, and trapezoids, which is not limited here.

[0061] Further, in embodiments of this invention, multiple needle assemblies 11 are defined as being arranged in a geometric array in the xy plane, and the multi-needle spinning module 10 also includes auxiliary electrodes. In one feasible embodiment, the multiple needle assemblies 11 are arranged along the x-direction, and two sets of auxiliary electrodes are provided. The two sets of auxiliary electrodes can be respectively disposed on both sides of the array of needle assembly 11 along the x-direction, and each set of auxiliary electrodes includes two auxiliary electrodes arranged side by side. Moreover, the auxiliary electrodes are positive voltage auxiliary electrodes, thereby reducing the electric field strength around the tip of the needle 111 of the needle assembly 11 during electrospinning by introducing positive voltage auxiliary electrodes. Alternatively, in another feasible embodiment, the multiple needle assemblies 11 are arranged along the x-direction, and two auxiliary electrodes are provided. The two auxiliary electrodes can be respectively disposed on both sides of the array of needle assembly 11 along the y-direction, and both are located at the center of the side of the array of needle assembly 11. Moreover, the auxiliary electrodes are grounded auxiliary electrodes, thereby increasing the electric field strength around the tip of the needle 111 of the needle assembly 11 during electrospinning by introducing grounded auxiliary electrodes. 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, thereby producing finer and more uniform polymer nanofibers through a more uniform electric field distribution.

[0062] Please see Figure 6 and Figure 7 In an embodiment of this utility model, a plurality of ribs 1111a are protruding from the outer wall of the end of the cylindrical part 1111 away from the conical part 1112. The ribs 1111a extend along the length direction of the cylindrical part 1111, and the plurality of ribs 1111a are arranged at intervals along the circumference of the cylindrical part 1111.

[0063] With this design, the structural strength of the cylindrical section 1111 can be enhanced by the reinforcing ribs 1111a.

[0064] Please see Figure 5 and Figure 6 In an embodiment of the present invention, the end of the rib 1111a facing the conical portion 1112 is formed with an inclined surface 1111b. One end of the inclined surface 1111b is located on the outer wall of the cylindrical portion 1111, and the other end is inclined outward along the radial direction of the cylindrical portion 1111 and in a direction away from the conical portion 1112.

[0065] Please see Figure 6 and Figure 7 In an embodiment of this utility model, the needle assembly 11 further includes an adapter 112, one end of which is inserted into the needle 111, and the other end is used to connect to the infusion assembly 12.

[0066] The adapter 112 has a liquid inlet channel that extends through both ends, and the liquid inlet channel is connected to the liquid outlet channel to deliver spinning solution to the liquid outlet channel.

[0067] The adapter 112 may have a threaded structure at one end facing the infusion assembly 12. The threaded structure may be either an internal thread or an external thread. This configuration allows the adapter 112 to be connected to the infusion assembly 12 via a threaded connection.

[0068] Please see Figure 7 In an embodiment of this utility model, the adapter 112 includes:

[0069] The main body 1121 has the liquid inlet channel formed therein. One end of the main body 1121 is inserted into the liquid inlet to connect the liquid inlet channel and the liquid outlet channel. The other end has a connecting structure for connecting the infusion assembly 12 externally.

[0070] A connecting part 1122 is sleeved on the periphery of the main body part 1121. One end of the connecting part 1122 is connected to the outer wall of the main body part 1121, and the other end is spaced apart from the outer wall of the main body part 1121 and surrounds the periphery of the cylindrical part 1111 so as to be threadedly engaged with the cylindrical part 1111.

[0071] Both ends of the connecting part 1122 may be provided with threaded structures. Correspondingly, the outer wall of the cylindrical part 1111, which is disposed opposite to the end of the connecting part 1122, may also be provided with threaded structures. This enables the threaded connection between the connecting part 1122 and the cylindrical part 1111, so as to facilitate the quick assembly and tight fit of the adapter 112 and the needle 111. The outer wall of the main body part 1121, which is disposed opposite to the other end of the connecting part 1122, may also be provided with threaded structures. This enables the threaded connection between the connecting part 1122 and the main body part 1121, so as to facilitate the quick assembly and tight fit of the main body part 1121 and the connecting part 1122.

[0072] Please see Figure 3 and Figure 4 In an embodiment of this utility model, the infusion assembly 12 includes:

[0073] Two first infusion lines 121 are arranged at intervals; and

[0074] A plurality of second infusion lines 122 are provided between two first infusion lines 121 and are respectively connected to two first infusion channels. The plurality of second infusion lines 122 are arranged at intervals in sequence.

[0075] The needle assembly 11 is provided in a plurality of manner, and the plurality of needle assemblies 11 are arranged sequentially at intervals along the length direction of the second infusion line 122 and are respectively connected to the second infusion line 122.

[0076] With this configuration, the spinning solution from the liquid supply mechanism 200 of the spinning equipment 1000 can first enter the first liquid delivery line 121, and then be diverted through the first liquid delivery line 121 to several second liquid delivery lines 122, and then diverted through the second liquid delivery lines 122 to several needle assembly 11 on each liquid delivery line. This enables the liquid supply function to several needle assembly 11, so that several needle assembly 11 of the multi-needle spinning module 10 can simultaneously perform liquid discharge and spinning.

[0077] Specifically, in some embodiments, the first infusion line 121 may have at least one inlet, which may, but is not limited to, be connected to a quick-connect fitting for connecting to an external infusion supply mechanism 200. The first infusion line 121 may also have several outlets, each outlet corresponding to a second infusion line 122. The outlets may, but are not limited to, be connected to quick-connect fittings for connecting to the second infusion line 122. The second infusion line 122 may initially have at least one inlet and several outlets. The inlet is used to connect to the first infusion line 121, and each outlet corresponds to a needle assembly 11 for detachable connection to an adapter 112 of the needle assembly 11.

[0078] Please see Figure 2 and Figure 3 In an embodiment of this utility model, the multi-needle spinning module 10 further includes:

[0079] Stage 13, the stage 13 having a receiving cavity 131 with a top opening 132, the infusion assembly 12 disposed within the receiving cavity 131, and the needle assembly 11 exposed through the opening 132; and

[0080] A drive assembly 14 is connected to the platform 13 for driving the platform 13 to move.

[0081] The carrier 13 of the multi-filament spinning module can serve as the mounting body for the infusion assembly 12 and the needle assembly 11 in the aforementioned embodiments. The carrier has a receiving cavity 131 with a top opening 132. The carrier 13 also has two through holes communicating with the receiving cavity 131. The two through holes are located on both sides of the carrier 13. The infusion assembly 12 is located in the receiving cavity 131. Two first infusion lines 121 are located on both sides of the receiving cavity 131. Each infusion line corresponds to a through hole so that the infusion supply mechanism 200 can be connected to the outside through the through hole.

[0082] This utility model also proposes a spinning mechanism 100, which includes a multi-needle spinning module 10. The specific structure of the multi-needle spinning module 10 is as described in the above embodiments. Since this spinning mechanism 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The spinning mechanism 100 also includes:

[0083] A receiving module 20 is mounted above the multi-needle spinning module 10. The receiving module 20 includes a receiving plate, which is positioned opposite to the needle assembly 11 of the multi-needle spinning module 10.

[0084] The power supply module 30 has its positive terminal electrically connected to the needle assembly 11 of the multi-needle spinning module 10, and its negative terminal electrically connected to the receiving plate of the receiving module 20. In this way, an electric field can be formed between the multi-needle spinning module 10 and the receiving module 20 to achieve electrospinning.

[0085] Specifically, during the electrospinning process, the multi-needle spinning module 10 in the aforementioned embodiment is supplied with spinning solution by the liquid supply mechanism 200, which can be configured as a polymer solution. The power supply module 30 is used to provide a high-voltage power supply. The positive terminal of the high-voltage power supply is connected to the multi-needle spinning module 10, and the negative terminal of the high-voltage power supply is connected to the receiving module 20, so that a potential difference is generated between the multi-needle spinning module 10 and the receiving module 20. At this time, the electrostatic force and the surface tension of the liquid on the polymer solution can work together to form an outward pulling force. Thus, when the electrostatic force exceeds the threshold voltage, the polymer droplets of the needle assembly 11 can be stretched under the drive of the electric field to form a jet. The diameter of the jet gradually decreases under the stretching action, and after high-speed stretching, solvent evaporation and solidification, it is finally deposited to form polymer nanofibers, which are collected by the receiving module 20.

[0086] Please see Figure 2 In an embodiment of this utility model, the spinning mechanism 100 further includes:

[0087] The machine body 40 has a spinning cavity formed inside it for housing the multi-needle spinning module 10 and the receiving module 20.

[0088] A circulation pipe 50, the two ends of which are respectively connected to the spinning chamber;

[0089] A blower 60, disposed in the circulation pipe 50, is used to drive air to circulate between the spinning chamber and the circulation pipe 50; and

[0090] A dehumidifier 70 is provided in the circulation pipe 50 and is used to absorb solvents in the air.

[0091] With this configuration, the internal air circulation of the spinning mechanism 100 can be achieved through the circulation pipe 50 and the fan 60.

[0092] In some embodiments, the fan 60 may be an axial flow fan 60, and the dehumidifier 70 may be a ceiling-mounted dehumidifier 70, installed on the top of the body 40. Specific implementation methods can be customized according to actual needs and are not limited here.

[0093] This utility model also proposes a spinning device 1000, which includes a spinning mechanism 100. The specific structure of the spinning mechanism 100 is as described in the above embodiments. Since this spinning device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0094] Please see Figure 1 In an embodiment of this utility model, the spinning equipment 1000 further includes a liquid supply mechanism 200, which includes a liquid storage component and a liquid supply pump. The liquid storage component has a liquid storage cavity for storing spinning liquid, and the liquid supply pump is used to pump the spinning liquid in the liquid storage cavity outward.

[0095] In this way, the spinning solution can be quantitatively supplied by the supply pump, which helps to ensure that the supply mechanism 200 has a stable outlet pressure.

[0096] Please see Figure 1 In an embodiment of this utility model, the spinning equipment 1000 further includes a winding mechanism 300 and an unwinding mechanism 400, which are respectively disposed at opposite ends of the spinning mechanism 100.

[0097] In some embodiments, both the winding mechanism 300 and the unwinding mechanism 400 can perform winding or unwinding by driving the guide rollers to rotate via a motor. Since the motor may reverse during operation, resulting in insufficient stability, in a feasible embodiment, the present invention can also provide a clutch mechanism at the motor to cooperate with it and prevent reverse rotation, thereby helping to ensure stable tension on the substrate.
