Description

Technical Field

[0001] This invention relates to the field of electrospinning equipment technology, and specifically to a ring-shaped electrospinning electrode that can achieve continuous operation. Background Technology

[0002] Electrospinning is a technology that uses a high-voltage electric field to prepare nanofibers from polymer solutions or melts. It is widely used in new materials, biomedicine, and new energy fields such as high-efficiency filtration membranes, lithium-ion battery separators, tissue engineering scaffolds, drug delivery systems, and solar cells. Its core lies in the design of the spinning electrode structure, which directly affects fiber uniformity, production continuity, and equipment stability. Early electrospinning used single-needle electrodes, such as capillary nozzles, with yields only in the milligram range per hour, resulting in low output and clogging issues, hindering industrial application. Multi-needle arrays, such as the cylindrical spiral nozzle in Chinese patent CN105937060A, while increasing output, suffer from "jet repulsion" due to electric field interference between needles, leading to large dispersion in fiber diameter distribution. Furthermore, open-supply modes, such as those in Chinese patent CN105937060A, suffer from rapid solvent evaporation and large fluctuations in spinning solution viscosity, resulting in poor uniformity of the fiber membrane. To overcome the defects of needle electrodes, needleless electrodes have become the mainstream direction, mainly including three types of structures: (1) Linear electrodes, such as Chinese patent CN101512052A, which uses metal ropes to form parallel spinning components between insulating end faces. Although it increases production, it has fatal defects: uneven tension of metal ropes leads to drift of spinning points and high randomness of fiber deposition; lack of online cleaning module, residual spinning liquid accumulation causes electrode resistance to rise, requiring frequent shutdown for cleaning; end face structure blocks electric field distribution, requiring additional high voltage. (2) Rotating disk / ring electrodes, such as Chinese patent CN111118678A, which gathers fibers through a cylindrical collector, but relies on external airflow to guide fiber movement, resulting in high energy consumption and susceptibility to environmental disturbances. More importantly, its electrode and solution tank separation design leads to large fluctuations in coating liquid volume, high coefficient of variation of fiber diameter, and the residual liquid on the electrode surface dries to form an insulating film. Chinese patent CN223033519U shows that it requires mechanical scraper for forced cleaning, and the scraping damage shortens the electrode life. (3) Reciprocating wound electrodes, such as Chinese patent CN218812278U, achieve limited continuous production by driving the metal wire to circulate through a winding wheel. However, two independent winding mechanisms are required, resulting in structural redundancy; the servo motor torque mode response delay is >0.5s, leading to difficulties in tension control. In particular, there is a lack of an integrated liquid supply-scraping system, and the open design of the coating tank still suffers from problems such as rapid solvent evaporation.

[0003] Based on a comprehensive analysis of existing patents, including the hexagonal tension adjustment in Chinese patent CN212533216U and the resistance heating scheme in CN101999016A, electrospinning electrodes still face three common problems that urgently need to be solved: (1) Continuity defects: electrode cleaning and spinning cannot be synchronized. Chinese patent CN223033519U uses a scraper to passively clean residual liquid, but scraper wear causes the cleaning efficiency to drop rapidly in a short time. (2) Insufficient uniformity: an open liquid supply system, such as Chinese patent CN105937060A, causes the solvent to evaporate rapidly, resulting in changes in solution viscosity and increased fiber diameter variation due to jet diameter fluctuations. (3) Poor stability: metal wire fatigue fracture. In Chinese patent CN218812278U, the lifespan of stainless steel oil wire is <500 hours; electric field interference restricts long-term operation. Chinese patent CN212533216U points out that the hexagonal end face only reduces the edge electric field attenuation to 25%.

[0004] Based on the aforementioned technical deficiencies, this invention provides a continuously operating annular electrospinning electrode that simultaneously achieves: (1) closed-loop liquid supply, reducing solvent evaporation rate through a sealed coating tank; (2) dynamic cleaning, integrating multi-stage scraping and online cleaning to eliminate residual liquid accumulation; and (3) synchronous control, with mechanical coupling between the drive and detection components to ensure tension stability. This invention provides a key path to overcome the bottleneck of continuous nanofiber production. Summary of the Invention

[0017] The drive component has a drive fixing plate fixed to the rear end below the protective plate, a drive mounting plate installed below the drive fixing plate, and a drive reinforcing plate installed on both the drive fixing plate and the drive mounting plate.

The movement of the detection pulley can drive the encoder to move synchronously, causing the detection shaft support plate, detection pulley, detection shaft, encoder mounting plate, encoder mounting bracket, encoder coupling, and encoder installed on the detection adjustment plate to move up and down simultaneously.

[0019] The tension of the drive belt is adjusted by adjusting the drive adjustment plate of the drive component; the tension of the driven belt is adjusted by adjusting the detection adjustment plate of the detection component.

[0020] After the servo motor of the drive component starts, the external active feeding system synchronously supplies spinning solution through the feeding conduit of the feeding component. The external active liquid supply system synchronously supplies cleaning solution to the cleaning brush holders I and II of the cleaning component. The external active air supply system supplies high-pressure air to the air drying tank of the cleaning component. The servo motor drives the scraping guide wheel of the scraping component to rotate via the drive belt, thereby driving the annular electrode wire to rotate. The annular electrode wire drives the feeding guide wheel of the feeding component to rotate, and the feeding guide wheel drives the encoder to rotate via the driven belt. The spinning solution enters the coating tank through the feeding pipe. Excess spinning solution overflows into the return tank and flows back to the external active feeding system through the return port. After the annular electrode wire passes through the coating tank, the spinning solution coats the annular electrode wire. After the annular electrode wire passes through the U-shaped wire passage in the coating tank, the excess spinning solution on the annular electrode wire is scraped off, making the amount of spinning solution on the annular electrode wire uniform. The annular electrode wire enters the spinning area to begin spinning. After spinning, the annular electrode wire sequentially enters scraper tubes II and I of the scraper component. The residual spinning solution on the annular electrode wire is scraped twice through the U-shaped wire passage holes on scraper tubes II and I to remove most of the residual material. The scraped-off residue enters the scraper box groove and flows to the external waste treatment system through the waste return port at the bottom of the scraper box groove. After passing through the scraper guide roller of the scraper component, the annular spinning electrode sequentially enters the cleaning brushes I and II of the cleaning component, where it is thoroughly cleaned by friction with the cleaning solution twice. Then, it enters the air drying tank, where the annular spinning electrode is dried by high-pressure airflow. The cleaned solution is returned to the external active liquid supply system through the return port on the cleaning tank. The annular electrode wire then sequentially passes through the feed guide roller of the feed component to begin the next coating spinning process, achieving continuous cyclic spinning.

[0021] The beneficial effects of this invention are: (1) The feeding adjustment block of the feeding component of the present invention is provided with orthogonal slot holes, which drives the coating tank and the return tank to achieve XYZ three-axis displacement, ensuring precise adjustment; the outlet of the liquid supply pipe is vertically aligned with the center of the coating tank, and the excess spinning liquid is circulated to the external system through the return port via the return tank, which greatly reduces the solvent evaporation rate and realizes gradient overflow liquid supply; the feeding guide wheel forms a linkage through pulley I, driven belt and detection pulley to form a mechanical synchronization mechanism.

[0022] (2) The scraper tube II of the scraper component of the present invention coarsely scrapes away most of the residual liquid, and the scraper tube I finely scrapes away the remaining residual liquid; the scraped residual liquid flows into the scraper box groove and is discharged through the waste return port to realize the self-recycling of waste.

[0023] (3) The nylon brush I and brush II of the cleaning component of the present invention mechanically scrub to remove surface deposits. Compressed air is passed through the air drying tank to dry the electrode wires with high-pressure airflow. Through three-stage cleaning, the electrodes can be recycled. The cleaning liquid is recovered through the return port and the overflow port controls the liquid level fluctuation to form a closed loop circulation of the cleaning liquid.

[0024] (4) The servo motor, drive coupling, drive shaft and drive pulley of the drive component of the present invention form a drive system, which drives the scraper guide wheel through the drive belt; the collaborative detection system monitors the linear speed in real time, and maintains the belt tension uniformly by raising and lowering the drive adjustment plate and the detection adjustment plate along the long slot hole, so as to achieve dynamic leveling.

[0044] like Figure 7 As shown, after the servo motor 706 of the drive component 700 of the present invention is started, the external active feeding system begins to synchronously supply spinning solution through the liquid supply pipe 208 of the feeding component 200, and the external active liquid supply system begins to synchronously supply cleaning solution to the cleaning brush holder I 403 and cleaning brush holder II 405 of the cleaning component 400, and the external active air supply system begins to supply high-pressure air to the air drying tank 406 of the cleaning component 400; the servo motor 706 drives the scraper guide wheel 506 of the scraper component 500 to rotate through the drive belt 600, thereby driving the annular electrode wire 300 to rotate, and through the annular electrode wire 300 to rotate. The annular electrode wire 300 drives the feeding guide wheel 209 of the feeding component 200 to rotate. The feeding guide wheel 209 drives the encoder 810 to rotate via the driven belt 900. The spinning solution enters the coating tank 207 through the supply pipe 208. Excess spinning solution overflows into the return tank 206 and flows back to the external active feeding system through the return port 204. After the annular electrode wire 300 passes through the coating tank 207, the spinning solution coats the annular electrode wire 300. After passing through the U-shaped wire passage hole of the coating tank 207, the excess spinning solution on the annular electrode wire 300 is removed. The spinning solution is scraped off to ensure a uniform amount of solution on the annular electrode wire 300. The annular electrode wire 300 then enters the spinning area to begin spinning. After spinning, the annular electrode wire 300 sequentially enters the scraper tubes II and I of the scraper component 500. The remaining spinning solution on the annular electrode wire 300 is scraped twice through the U-shaped wire passage holes on the scraper tubes II and I to remove most of the residual material. The scraped-off residual material enters the scraper box groove 512 and flows out through the waste return port 409 at the bottom of the scraper box groove 512. In the external waste treatment system, the annular electrode wire 300 passes through the scraper guide roller 506 of the scraper component 500 and then sequentially enters the cleaning brush I 402 and cleaning brush II 404 of the cleaning component 400. It is continuously cleaned by friction with the cleaning liquid twice. Then it enters the air drying tank 406 and is dried by high pressure air. The cleaned cleaning liquid flows back to the external active liquid supply system through the return port 204 on the cleaning tank 401. The annular electrode wire 300 passes through the feed guide roller 209 of the feed component 200 and begins the next coating and spinning process.
