[0037] See also Figure 1-11A nanofiber filter layer production device includes a reel-out end 10, a reel-in end 20, a mounting shell 30, a reciprocating dripping mechanism 40 and a high-pressure device 70. The reciprocating dripping mechanism 40 includes a plurality of rope bodies 43, a plurality of liquid droplet discharge devices 44, a fixing plate 45 and a side driving member 46. The liquid droplet discharge device 44 includes a liquid discharge nozzle 441 and a connecting member 442. The liquid discharge nozzle 441 is fixed to the connecting member 442, and the liquid discharge nozzle 441 is located at the lower side of the rope body 43. The liquid droplet discharge device 44 is fixed to the fixed plate 45, and the side driving member 46 drives the fixed plate 45 to move back and forth. The rope body 43 is located above the liquid droplet discharge device 44; the unwinding end 10 and the winding end 20 are distributed on both sides of the installation shell 30, and the substrate 200 is wound up by the winding end 20 after being released by the unwinding end 10. The high-pressure device 70 is fixed inside the installation shell 30 and forms a high-pressure section 80 in the installation shell 30. The substrate 200 moves along the high-pressure section 80, and the reciprocating dripping mechanism 40 drops material droplets onto the rope body 43. The material droplets are drawn upward under the action of the high-pressure section 80 and covered on the substrate 200. During operation, as the material droplets are drawn upward to cover the substrate 200 and the substrate 200 moves from the unwinding end 10 to the winding end 20, the drawing forms a nanofiber layer on the substrate 200. The arrangement of the unwinding end 10 and the winding end 20 makes the coverage of the nanofiber layer continuous, thereby ensuring the continuous operation of the entire equipment and improving production efficiency. The high-pressure device 70 forms an upward power, and the liquid outlet nozzle 441 is located at the lower side of the rope body 43. The liquid outlet nozzle 441 discharges liquid along the side of the rope body 43. The liquid moves upward under the action of the high-pressure interval, and the droplets contact the lower part of the rope body 43 and then draw upward. The contact area between the droplets and the rope body 43 is increased, the drawing effect is good, the drawing is made finer, and the density and pore size of the nanofiber layer are ensured, and the filtering effect of the nanofiber layer is improved. At the same time, the inclined liquid outlet solves the problem of blocking interference.

[0038] Preferably, the reciprocating drip mechanism 40 further comprises a rope body fixing structure 41 and a plurality of side fixing members 42 distributed on both sides of the rope body fixing structure 41, wherein the side fixing members 42 are fixed to the rope body fixing structure 41, and the rope body fixing structure 41 comprises a main body 411 and mounting plates on both sides of the main body 411, wherein the main body 411 is U-shaped, and the upper part of the main body 411 corresponds to the rope body 43, and the mounting plates are correspondingly mounted with the side fixing members 42, and the arrangement of the main body 411 facilitates the cleaning of the rope body 43 area. The end of the rope body 43 is clamped and fixed to the side fixing members 42. Specifically, the side fixing members 42 comprise a fixing clamp 421 and a fixing screw 422, wherein the fixing clamp 421 is provided with a clamping gap 4211, wherein the fixing screw 422 passes through the fixing clamp 421 and is screwed to the fixing clamp 421, wherein the end of the rope body 43 is located in the clamping gap 4211, and the bottom of the fixing screw 422 abuts against the rope body 43. The rope body 43 is fixed by the fixing clamp 421 and the fixing screw 422, and the disassembly and maintenance are simple and convenient, and the operation is convenient.

[0039] It should be noted that the fineness of the droplet wire drawing determines the pore size of the nanofiber layer, and the pore size of the nanofiber layer determines the effect of physical filtration; it is divided into four levels for explanation: at the first level, if the droplet acts directly in the high-pressure interval, the diameter of the droplet wire drawing is R1 and the pore size is L1; at the second level, the droplet flows downward and contacts the rope body in the opposite direction of the high-pressure interval, which obviously affects the wire drawing effect, and the diameter of the droplet wire drawing is R2 and the pore size is L2; ​​at the third level, the droplet flows upward and contacts the rope body in the same direction as the high-pressure interval, and the diameter of the droplet wire drawing is R3 and the pore size is L3; at the fourth level, the rope body is a steel wire rope, and the droplet flows upward and contacts the rope body in the same direction as the high-pressure interval, and the diameter of the droplet wire drawing is R4 and the pore size is L4. Obviously, R1>R2>R3>R4, L1>L2>L3>L4, so the pore size of the nanofiber layer at the fourth level is the smallest and the filtration effect is the best.

[0040] Preferably, the rope body 43 is a steel wire rope, and the rope body 43 extends along the length direction of the rope body fixing structure 41. The steel wire rope has a twisting effect, which further increases the contact area between the droplet and the steel wire rope, ensuring the wire drawing effect.

[0041] Preferably, the liquid droplet discharge device 44 includes two liquid discharge nozzles 441, the connecting member 442 is provided with a concave groove 4421, two inclined end surfaces 4422 are formed on both sides of the concave groove 4421, and the two liquid discharge nozzles 441 are respectively fixed on the two inclined end surfaces 4422. Specifically, the liquid discharge nozzle 441 is perpendicular to the inclined end surface 4422, and the two liquid discharge nozzles 441 correspond to one rope body 43. The rope body 43 is double-sided wiredrawing, which has a wider coverage area than single-sided wiredrawing. At the same time, the two liquid discharge nozzles 441 correspond to one rope body 43 and act simultaneously, which ensures the density of the nanofiber layer. Since two liquid discharge nozzles 441 correspond to the lower side of a rope body 43, on the one hand, the density of the fiber layer corresponding to the area where the single rope body 43 is located is guaranteed, and on the other hand, such an arrangement allows more liquid discharge nozzles 441 to be arranged in the same space, so that the density of the fiber layer reaches the highest.

[0042] Preferably, the rope body 43 is distributed in the middle of the liquid droplet discharge device 44, and the two liquid discharge nozzles 441 are at an acute angle. Specifically, the intersection of the extension lines of the two liquid discharge nozzles 441 coincides with the rope body 43. After the liquid droplets come out from the liquid discharge nozzles 441, they move toward the rope body 43 under the combined action of the force of the liquid discharge nozzles 441 and the force of the high-pressure zone, thereby ensuring the liquid discharge effect and high utilization rate.

[0043] Preferably, the nanofiber filter layer production device further comprises a side fan 60 and two guide rollers 90, wherein the side fan 60 is located in the mounting housing 30, and the substrate 200 passes around the guide rollers 90. The guide rollers 90 improve the smoothness of the movement of the substrate 200.

[0044] Preferably, the mounting shell 30 includes an upper protection frame 31, a mounting platform 32 fixed to the lower part of the upper protection frame 31, and the mounting platform 32 is provided with a switch door 321; the side driving member 46 includes a driving motor 461, a screw rod 462, and a mounting end 463, the driving motor 461 drives the screw rod 462 to rotate, and the mounting end 463 is screwed to the screw rod 462. A box filled with liquid is provided in the mounting platform 32, and the box is slidably installed in the mounting platform 32. Specifically, the liquid is melted nanofiber particles, with novel structure, ingenious design, strong applicability, and easy promotion.

[0045] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
