[0002] The electrospinning machine nozzle is a key component in the electrospinning technology. The electrospinning machine nozzle is mainly divided into many types, including but not limited to single-needle nozzle, multi-needle nozzle, needleless nozzle (such as static nozzle and dynamic nozzle) and specially designed nozzle (such as side-by-side nozzle, confluence nozzle, confluence nozzle, etc.). Different types of nozzles have different structures and characteristics to meet different spinning needs. The cleaning and maintenance of the electrospinning machine nozzle is very important to maintain the spinning quality and extend the service life of the nozzle.

[0032] The above scheme is adopted: the waterproof telescopic electric cylinder 21 in the chassis 1 is started to drive the rubber long plate 22 to move downward, so that the nozzle gradually moves downward to contact the four-corner scraper rod 232, and the nozzle is through-holed. At the same time, when the telescopic electric cylinder 21 moves downward, it will also synchronously drive the rubber pad 24 to move downward in the piston syringe 25, thereby squeezing the soaking solution that has been sucked into its inner cavity in advance, and driving the water wheel rod 26 in the piston syringe 25 to rotate, so that the multiple ball rods 27 will then slide and engage into the ball grooves 29 on the spur gear 1 28 respectively, so that the spur gear 1 28 rotates synchronously, and the rotation of the spur gear 1 28 drives the meshing spur gear 2 230 to rotate, so as to synchronously drive the rotation of the rotating rod 231 and the four-corner scraper rod 232, thereby the inner wall of the horizontally downward-moving nozzle can be removed by the four-corner scraper rod 232, and its inner wall can be effectively and quickly cleaned;

[0033] At the same time, through the synchronous passive downward movement of the rubber long plate 22 and the T-shaped slider 242, the L-shaped plate frame 238 that is magnetically attracted to the T-shaped slider 242 will be guided downward in the plate groove 239. The downward movement of the L-shaped plate frame 238 will stretch the bellows 235. Subsequently, when the telescopic electric cylinder 21 moves up and resets, the water in the bellows 235 will be squeezed in real time, and then will be ejected from the two nozzles 237, thereby spraying to the surface of the nozzle, cleaning the immersion solution on its surface, and producing a flushing effect.

[0034] The transmission structure includes a rubber pad 24 fixedly connected to the telescopic electric cylinder 21, and a piston syringe 25 can be slidably connected to the outer wall of the rubber pad 24. The bottom end of the piston syringe 25 is fixedly connected to the outer wall of one end of the telescopic electric cylinder 21. The telescopic rod body of the telescopic electric cylinder 21 is also slidably connected to the top of the piston syringe 25. The two ends of the piston syringe 25 near the bottom are jointly movably sleeved with a water wheel rod 26. A plurality of ball rods 27 are fixedly connected to the rod body on both sides of the water wheel rod 26 in an axial point-type surrounding manner. The bottom ends of the four four-corner scraper rods 232 are fixedly connected to a rotating rod 231, two of which are The rotating rods 231 are fixedly connected with spur gears 28, and the other two rotating rods 231 are fixedly connected with spur gears 230. The bottom ends of the four rotating rods 231 are movably connected with the inner wall of the bottom end of the chassis 1. The two spur gears 28 are respectively meshed with the two spur gears 230, and the bottom ends of the two spur gears 28 are surrounded by a plurality of ball grooves 29. The two groups of ball grooves 29 can be respectively intermittently slidably engaged with the two groups of ball rods 27. The two groups of ball rods 27 are composed of two sections of different materials, the rod body is made of metal, and the ball body is made of natural rubber.

[0035] The above scheme is adopted: the disassembled nozzle is manually inserted into the slot 23 on the rubber long plate 22, and the nozzle is tightly limited without damaging the outer wall. Then, the waterproof telescopic electric cylinder 21 in the chassis 1 is started to drive the rubber long plate 22 to move downward. As a result, the nozzle is gradually moved downward and contacted with the four-corner scraper rods 232 under the drive of the telescopic electric cylinder 21, and the nozzle is through-holed. At the same time, when the telescopic electric cylinder 21 moves downward, it will also synchronously drive the rubber pad 24 to move downward in the piston syringe 25, thereby squeezing the immersion solution that has been sucked into its inner cavity in advance, and the immersion solution is passively pushed out of the piston syringe 2 5, it will synchronously drive the water wheel rod 26 in the piston syringe 25 to rotate, thereby the rotation of the water wheel rod 26 will synchronously drive the multiple ball rods 27 to rotate, and the rotating multiple ball rods 27 will then slide and engage into the ball grooves 29 on the spur gear 1 28, so that the spur gear 1 28 rotates synchronously, and the rotation of the spur gear 1 28 drives the meshing spur gear 2 230 to rotate, so as to synchronously drive the rotation of the rotating rod 231 and the four-corner scraper rods 232, thereby the inner wall of the horizontally downward-moving nozzle can be rotary-type removed by the four-corner scraper rods 232, and its inner wall can be effectively and quickly cleaned.

[0036] The two extrusion structures each include a bracket 233 fixedly connected to the outer wall of one side of the top of the chassis 1, a water tank 234 is fixedly connected to the top of the bracket 233, the top tube body of the bellows 235 is respectively connected to the bracket 233 and one end of the water tank 234, the bellows 235 is specifically composed of two sections of different materials, the upper half is a straight-tube hard material, and the lower half is a telescopic and extrudable tube body, the bottom end of the bellows 235 is fixedly connected to an L-shaped plate frame 238, and a portion of the outer wall of one end of the chassis 1 is provided with a portion that can be connected to the L-shaped plate frame. 238 is slidably connected to a plate groove 239, and arc angle grooves 240 are also provided in the inner walls at both ends of the plate groove 239. The outer walls at both ends of the L-shaped plate frame 238 are fixedly connected with arc angle blocks 241 that can fit and slide with the inner walls of the two arc angle grooves 240. The L-shaped plate frame 238 is specifically a magnetic plate, and a T-shaped slider 242 is magnetically attracted on one side of the L-shaped plate frame 238. A T-shaped groove 243 is provided on the inner wall at one end of the chassis 1 for sliding engagement with the T-shaped slider 242, and one end of the T-shaped slider 242 is fixedly connected to the outer wall of the rubber long plate 22.

[0037] The above scheme is adopted: through the synchronous passive downward movement of the rubber long plate 22 and the T-shaped slider 242, the L-shaped plate frame 238 that is magnetically attracted to the T-shaped slider 242 will be guided downward in the plate groove 239, and the arc blocks 241 on both ends of the L-shaped plate frame 238 will slide in the arc slide groove 240 in a card-connected manner, which increases the limiting effect of the horizontal movement of the L-shaped plate frame 238. The downward movement of the L-shaped plate frame 238 will stretch the bellows 235, so that it can suck the water in the water tank 234. Subsequently, when the telescopic electric cylinder 21 moves up and resets, it indirectly drives the bellows 235 to reset. The water in the bellows 235 will be squeezed in real time, and then it will be ejected from the two nozzles 237, thereby spraying to the surface of the nozzle, cleaning the soaking solution on its surface, and producing a flushing effect.

[0038] A filter disc 244 is fixedly connected to the inner wall of one side at the bottom end of the piston syringe 25, an elastic telescopic member 245 is fixedly connected to the top outer wall of the filter disc 244, a through-hole disc 246 is fixedly connected to the top of the elastic telescopic member 245, and the through-hole disc 246 and the filter disc 244 can be slidably connected in a fitting manner.

[0039] The above scheme is adopted: when the telescopic electric cylinder 21 moves upward to drive the rubber pad 24 to move upward in the piston syringe 25 to suck the soaking solution, the filter disc 244 will screen the soaking solution to prevent the material dropped after the nozzle is soaked from entering the piston syringe 25 together with the solution, and as the suction force is generated, the through-hole disc 246 will be sucked upward together with the elastic telescopic part 245. When the telescopic electric cylinder 21 moves downward, the through-hole disc 246 will be passively reset. That is, the filter holes on the filter disc 244 can be pierced through the through-hole disc 246 to avoid material blockage.

[0040] The working principle and use process of the present invention are as follows: by pouring the soaking solution into the chassis 1 in advance, and then manually clamping the disassembled nozzle into the slot 23 on the rubber long plate 22, the nozzle is tightly limited without damaging the outer wall, and then the waterproof telescopic electric cylinder 21 in the chassis 1 is started to drive the rubber long plate 22 to move downward. During the downward movement, the T-shaped slider 242 installed on both ends will be guided and slid in the T-shaped slide groove 243, so that the nozzle will gradually move downward and contact the four-corner scraper rod 232 under the drive of the telescopic electric cylinder 21, and the nozzle will be through-holed. At the same time, when the telescopic electric cylinder 21 moves downward, it will also synchronously drive the rubber pad 24 to move downward in the piston syringe 25, thereby squeezing the inner cavity that has been previously When the soaking solution sucked in is passively pushed out of the piston syringe 25, the water wheel rod 26 in the piston syringe 25 will be synchronously driven to rotate, thereby the rotation of the water wheel rod 26 will synchronously drive the multiple ball rods 27 to rotate, and the rotating multiple ball rods 27 will then slide and engage in the ball grooves 29 on the spur gear 1 28 respectively, and then the continuous rotation of the multiple ball rods 27 will cause the spur gear 1 28 to rotate synchronously, and the rotation of the spur gear 1 28 drives the meshing spur gear 2 230 to rotate, so as to synchronously drive the rotation of the rotating rod 231 and the four-corner scraper rods 232, thereby the four-corner scraper rods 232 can be used to perform rotational material removal on the inner wall of the horizontally downward-moving nozzle, and its inner wall can be effectively and quickly cleaned;

[0041] At the same time, the synchronous passive downward movement of the rubber long plate 22 and the T-shaped slider 242 will simultaneously drive the L-shaped plate frame 238 that is magnetically attracted to the T-shaped slider 242 to be guided downward in the plate groove 239, and the arc blocks 241 on both ends of the L-shaped plate frame 238 are snap-connected and slid in the arc slide groove 240, which increases the limiting effect on the horizontal movement of the L-shaped plate frame 238. The downward movement of the L-shaped plate frame 238 will stretch the bellows 235, so that it can suck the water in the water tank 234. Later, when the telescopic electric cylinder 21 moves upward and resets, it indirectly drives the bellows 235 to reset. The water in the bellows 235 will be squeezed in real time, and then it will be ejected from the two nozzles 237, so as to be sprayed to the surface of the nozzle, and the soaking solution on the surface is cleaned, producing a flushing effect.

[0042] Finally, when the telescopic electric cylinder 21 moves upward to drive the rubber pad 24 to move upward in the piston syringe 25 to suck the soaking solution, the filter disc 244 will screen the soaking solution to prevent the material dropped after the nozzle is soaked from entering the piston syringe 25 together with the solution, and as the suction force is generated, the through-hole disc 246 will be sucked upward together with the elastic telescopic part 245. When the telescopic electric cylinder 21 moves downward, the through-hole disc 246 will be passively reset. In other words, the filter holes on the filter disc 244 can be pierced through the through-hole disc 246 to prevent material clogging and affect the cleaning of the nozzle by the overall device.
