The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] See also Figure 1-11A contactless self-cleaning needle-free electrospinning nozzle device includes a driving mechanism 10, a fixing seat 20, a plurality of steel wire ropes 30, a nozzle self-cleaning device 40, a nozzle device 60 and a connecting member 70. The nozzle self-cleaning device 40 includes a first driving member 41, a mounting frame 42, a second driving member 43, a cleaning rotating rod 44 and a plurality of steel wire cleaning wheels 45 mounted on the cleaning rotating rod 44. The first driving member 41 is fixed to the mounting frame 42, the first driving member 41 is fixedly connected to the second driving member 43 and drives the second driving member 43 to rotate. The part 43 moves up and down, the second driving part 43 is fixedly connected to the cleaning rotating rod 44 and drives the cleaning rotating rod 44 to rotate; the nozzle device 60 includes a nozzle body, and the nozzle body is provided with a side nozzle 61, and the side nozzle 61 is located on the side and lower side of the wire rope 30, and the two ends of the wire rope 30 are respectively fixed to the two ends of the fixing seat 20, the mounting frame 42 and the nozzle device 60 are fixed to the connecting member 70, and the driving mechanism 10 drives the connecting member 70 to move back and forth along the length direction of the wire rope 30. The material on the wire rope 30 is cleaned by the cooperation of the first driving member 41, the mounting bracket 42, the second driving member 43, the cleaning rotating rod 44 and several members installed on the cleaning rotating rod 44. The cleaning can be performed when the equipment is running, and can be automatically cleaned when the equipment stops, which solves the problem of low cleaning efficiency. At the same time, the side nozzle 61 is located on the side of the wire rope 30 to avoid blocking the drawing of the droplets, thereby improving production efficiency and reducing the possibility of material droplets sticking to the nozzle device 60. There is no need to clean the nozzle device 60 regularly.

[0037] Specifically, in actual application, the contactless self-cleaning needle-free electrospinning nozzle device is located in the high-voltage interval. After the material droplets are sprayed out from the side nozzle 61, they move toward the wire rope 30 and adhere to the wire rope 30 under the combined action of the high-voltage interval and the nozzle ejection force, and are then drawn through the action of the high-voltage interval.

[0038] When in the cleaning state, the first drive member 41 operates to cause the wire cleaning wheel 45 to contact the wire rope 30. A mating groove 451 is provided in the center of the wire cleaning wheel 45 to mate with the wire rope 30. Specifically, the first drive member 41 is a drive cylinder, and the second drive member 43 is a side-rotating motor. The first drive member 41 is perpendicular to the second drive member 43. The second drive member 43 rotates to remove excess material from the wire rope 30 through the wire cleaning wheel 45, preventing clogging.

[0039] Preferably, when in working state, there are two modes:

[0040] In the normal mode, the first driving member 41 operates to move the wire cleaning wheel 45 away from the wire rope 30 , and a clearance gap is formed between the wire cleaning wheel 45 and the wire rope 30 .

[0041] In the high-efficiency mode, the first driving member 41 operates to make the wire cleaning wheel 45 fit the wire rope 30. While the nozzle device 60 discharges liquid normally, the wire cleaning wheel 45 located on the side of the nozzle device 60 performs immediate cleaning.

[0042] Preferably, each of the nozzle devices 60 is provided with two nozzle self-cleaning devices 40, and the nozzle device 60 is located between the two nozzle self-cleaning devices 40. The connecting member 70 is flat, and the mounting frame 42 is perpendicular to the connecting member 70. Because the nozzle device 60 is located between the two nozzle self-cleaning devices 40, the nozzle self-cleaning device 40 cleans the nozzle device 60 before and after the liquid is discharged. For the convenience of description, the two nozzle self-cleaning devices 40 are referred to as the first cleaning device and the second cleaning device. On the wire rope 30, the first cleaning device and the second cleaning device clean the nozzle device 60 before and after the liquid is dripped, and the cleaning effect is good.

[0043] Preferably, the driving mechanism 10 includes a driving motor 11, a transmission screw 12, and a U-shaped movable seat 13. The driving motor 11 drives the transmission screw 12 to rotate. The U-shaped movable seat 13 is screwed to the transmission screw 12. The U-shaped movable seat 13 is fixedly connected to the connecting member 70. It has a novel structure, ingenious design, strong applicability, and is easy to promote.

[0044] Preferably, each nozzle body is provided with two side nozzles 61, the steel wire rope 30 is located between the two side nozzles 61, and the angle between the two side nozzles 61 is 30°-80°. If the liquid spraying device is in the shape of a square box, the liquid spraying device will block part of the steel wire rope 30 after passing through the steel wire rope 30, thereby affecting the wire drawing efficiency.

[0045] The above 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 replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
