Description

Technical Field

[0001] The present invention belongs to the technical field of electrospinning, and particularly relates to an electrospinning device. Background Art

[0002] Currently, the main forms of high-voltage electrospinning are needle type, wire electrode coating type, etc. The process of spinning using a needle-type electrospinning device is as follows: The solution is pushed by a feeding pump or the like through a needle with a positive high voltage, and the receiving end is grounded or connected to a negative high voltage. Under the action of the electric field, a Taylor cone is formed at the tip of the needle, and fiber filaments are extended from the tip of the cone. However, when using a needle-type electrospinning device for spinning, there are disadvantages such as low spinning efficiency, troublesome installation / cleaning of the needle, easy blockage of the needle, and easy dripping during the spinning process. The process of spinning using a wire electrode coating type electrospinning device is as follows: The solution is applied to a wire electrode with a positive high voltage through a moving mechanism, and the receiving end is grounded or connected to a negative high voltage. Under the action of the electric field, spinning is carried out. However, when using a wire electrode coating type electrospinning device for spinning, there are disadvantages such as low spinning efficiency, uneven coating, troublesome cleaning of the coating device, and low efficiency of the moving mechanism.

[0032] Embodiment 1

[0033] As Figures 1-8 As shown, this embodiment relates to an electrospinning device, which includes a frame 1. A plurality of wire electrodes 6 extending transversely are fixed on the frame 1. The plurality of wire electrodes 6 are arranged in rows longitudinally. Each wire electrode 6 is connected to a positive high-voltage power supply 7. A receiving end 4 is arranged above the plurality of wire electrodes 6. The receiving end 4 is connected to a negative high-voltage power supply 8 (it should be noted that the receiving end 4 can also be grounded); below each wire electrode 6, a liquid tank 3 filled with a spinning solution is correspondingly provided. The liquid tank 3 has the same extension direction and arrangement as the wire electrode 6. The liquid tank 3 can reciprocate up and down relative to the wire electrode 6, so that the wire electrode 6 reciprocally switches between the dipping state immersed in the spinning solution and the spinning state separated from the spinning solution; the liquid tank 3 is divided into two groups, namely a first liquid tank 31 and a second liquid tank 32; the frame 1 is equipped with a driving mechanism 5 for driving the first liquid tank 31 and the second liquid tank 32 to reciprocate in opposite directions. The driving mechanism 5 is connected to the first liquid tank 31 and the second liquid tank 32.

[0034] For the above electrospinning device, the driving mechanism 5 drives the first liquid tank 31 and the second liquid tank 32 to alternately move up and down, so as to ensure that there is always a wire electrode 6 in the spinning state separated from the spinning solution, realizing continuous batch spinning with high spinning efficiency. Moreover, for the above electrospinning device, the liquid tank 3 is used to hold the spinning solution. The wire electrode 6 reciprocally switches between the dipping state immersed in the spinning solution and the spinning state separated from the spinning solution through the up and down reciprocating movement of the liquid tank 3. The liquid supply is more convenient and conducive to cleaning. At the same time, the spinning solution in the liquid tank 3 supplies the wire electrode 6 by submerging the wire electrode 6, so that the wire electrode 6 is evenly dipped with the spinning solution everywhere, and the spinning is more uniform.

The fourth support seat 5071 is arranged vertically, the upper end of the fourth support seat 5071 is fixedly connected to the bottom surface of the second liquid tank 32, one end of the fourth rocker arm 5072 is hinged to the lower end of the fourth support seat 5071, and the other end of the fourth rocker arm 5072 is fixedly connected to the outer circumference of the third rotating shaft 503; the first support seat 5041 is located on the left side of the first rotating shaft 501 in the transverse direction, the third support seat 5061 is located on the right side of the first rotating shaft 501 in the transverse direction. Both the first rocker arm 5042 and the third rocker arm 5062 are perpendicular to the first rotating shaft 501, and the first rocker arm 5042 extends towards the left side in the transverse direction, and the third rocker arm 5062 extends towards the right side in the transverse direction; the second rocker arm 5052 is perpendicular to the second rotating shaft 502, and the extending direction of the second rocker arm 5052 is the same as that of the first rocker arm 5042. The second support seat 5051 is located on the side of the second rotating shaft 502 where the second rocker arm 5052 is provided;The fourth swing arm 5072 is perpendicular to the third rotating shaft 503, and the extending direction of the fourth swing arm 5072 is the same as that of the third swing arm 5062. The fourth support seat 5071 is located on the side of the third rotating shaft 503 where the fourth swing arm 5072 is provided; the second rotating shaft 502 is linked with the first rotating shaft 501 through the first connecting rod 508, and the third rotating shaft 503 is linked with the first rotating shaft 501 through the second connecting rod 509. Both the first connecting rod 508 and the second connecting rod 509 are arranged horizontally and are both located below the first rotating shaft 501, the second rotating shaft 502 and the third rotating shaft 503; one end of the first connecting rod 508 close to the first rotating shaft 501 is hinged with a fifth swing arm 510, the upper end of the fifth swing arm 510 is fixedly connected to the outer periphery of the first rotating shaft 501, one end of the first connecting rod 508 close to the second rotating shaft 502 is hinged with a sixth swing arm 511, the upper end of the sixth swing arm 511 is fixedly connected to the outer periphery of the second rotating shaft 502, one end of the second connecting rod 509 close to the first rotating shaft 501 is hinged with a seventh swing arm 512, the upper end of the seventh swing arm 512 is fixedly connected to the outer periphery of the first rotating shaft 501, and one end of the second connecting rod 509 close to the third rotating shaft 503 is hinged with an eighth swing arm 513, the upper end of the eighth swing arm 513 is fixedly connected to the outer periphery of the third rotating shaft 503; the first connecting rod 508 is connected with a driving assembly 514 for driving the first connecting rod 508 to reciprocate horizontally.;

[0036] The driving process of the above driving mechanism 5 is as follows: As Figure 5 shown, the driving assembly 514 drives the first connecting rod 508 to move leftward horizontally. The connection end of the fifth swing arm 510 and the first connecting rod 508 and the connection end of the sixth swing arm 511 and the first connecting rod 508 swing leftward simultaneously. While swinging, the fifth swing arm 510 drives the first rotating shaft 501 to rotate clockwise, and while swinging, the sixth swing arm 511 drives the second rotating shaft 502 to rotate clockwise. While rotating clockwise, the first rotating shaft 501 drives the first swing arm 5042 to swing upward, thereby pushing the first support seat 5041 to move upward. While rotating clockwise, the second rotating shaft 502 drives the second swing arm 5052 to swing upward, thereby pushing the second support seat 5051 to move upward. The first liquid tank 31 moves upward under the combined push of the first support seat 5041 and the second support seat 5051, so that the wire electrode 6 corresponding to the first liquid tank 31 is immersed in the spinning solution and enters the liquid dipping state; As Figure 6As shown, while the first rotating shaft 501 rotates clockwise, it also drives the seventh rocker arm 512 to swing leftward, thereby pushing the second connecting rod 509 to move leftward in the horizontal direction. The connecting end of the eighth rocker arm 513 and the second connecting rod 509 swings leftward synchronously. While the eighth rocker arm 513 swings, it drives the third rotating shaft 503 to rotate clockwise. While the first rotating shaft 501 rotates clockwise, it further drives the third rocker arm 5062 to swing downward, thereby driving the third support base 5061 to move downward. While the third rotating shaft 503 rotates clockwise, it drives the fourth rocker arm 5072 to swing downward, thereby driving the fourth support base 5071 to move downward. The second liquid tank 32 moves downward under the combined drive of the third support base 5061 and the fourth support base 5071, causing the wire electrode 6 corresponding to the second liquid tank 32 to separate from the spinning solution and enter the spinning state; furthermore, as Figure 7 shown, the driving assembly 514 drives the first connecting rod 508 to move rightward in the horizontal direction. The connecting end of the fifth rocker arm 510 and the first connecting rod 508 and the connecting end of the sixth rocker arm 511 and the first connecting rod 508 swing rightward simultaneously. While the fifth rocker arm 510 swings, it drives the first rotating shaft 501 to rotate counterclockwise. While the sixth rocker arm 511 swings, it drives the second rotating shaft 502 to rotate counterclockwise. While the first rotating shaft 501 rotates counterclockwise, it drives the first rocker arm 5042 to swing downward, thereby driving the first support base 5041 to move downward. While the second rotating shaft 502 rotates counterclockwise, it drives the second rocker arm 5052 to swing downward, thereby driving the second support base 5051 to move downward. The first liquid tank 31 moves downward under the combined drive of the first support base 5041 and the second support base 5051, causing the wire electrode 6 corresponding to the first liquid tank 31 to separate from the spinning solution and enter the spinning state; as Figure 8As shown, while the first rotating shaft 501 rotates counterclockwise, it also drives the seventh rocker arm 512 to swing to the right, thereby pushing the second connecting rod 509 to move horizontally to the right. The connecting end of the eighth rocker arm 513 and the second connecting rod 509 swings to the right synchronously. While the eighth rocker arm 513 swings, it drives the third rotating shaft 503 to rotate counterclockwise. While the first rotating shaft 501 rotates counterclockwise, it further drives the third rocker arm 5062 to swing upward, thereby pushing the third support base 5061 to move upward. While the third rotating shaft 503 rotates counterclockwise, it drives the fourth rocker arm 5072 to swing upward, thereby pushing the fourth support base 5071 to move upward. The second liquid tank 32 moves upward under the combined push of the third support base 5061 and the fourth support base 5071, so that the wire electrode 6 corresponding to the second liquid tank 32 is immersed in the spinning solution and enters the liquid dipping state. With the driving mechanism 5 of the above structure, it is realized that a set of driving mechanism 5 drives the first liquid tank 31 and the second liquid tank 32 to perform reciprocating motions in opposite directions at the same time, with high driving efficiency, and the reciprocating motion processes of the first liquid tank 31 and the second liquid tank 32 are stable, without rapid drops or rises. It can be understood that in the above driving mechanism 5, the driving component 514 can also be connected to the second connecting rod 509. During driving, the second connecting rod 509 is driven through the driving component 514, and then transmitted to the first connecting rod 508. The specific transmission process is similar to the process of transmitting from the first connecting rod 508 to the second connecting rod 509, and will not be elaborated here. It should be noted that the setting positions of the first support base 5041 and the third support base 5061 relative to the first rotating shaft 501 can be exchanged with each other, then the moving directions of the first liquid tank 31 and the second liquid tank 32 are also exchanged accordingly, and the specific driving process is similar to the above, and will not be elaborated here.

[0037] It should be noted that, as Figure 3 shown, in this embodiment, the first liquid tank 31 and the second liquid tank 32 are arranged alternately one by one. Correspondingly, as Figure 4 shown, the first transmission component 504 and the third transmission component 506 on the first rotating shaft 501 are arranged alternately one by one, and the second transmission component 505 on the second rotating shaft 502 and the fourth transmission component 507 on the third rotating shaft 503 are arranged alternately one by one in a staggered manner. By arranging the first liquid tank 31 and the second liquid tank 32 in this way, the spinning can be made more uniform.

[0038] As Figure 4 , Figure 5 , Figure 7 and Figure 9As shown, in this embodiment, the driving assembly 514 includes a motor 5141 for providing driving force, and a cam 5142 drivingly connected to the first link 508. The axle 51421 of the cam 5142 is drivingly connected to the output shaft of the motor 5141. When driving, the motor 5141 provides driving force to drive the cam 5142 to rotate, and then drives the first link 508 to reciprocate laterally through the cam 5142. Specifically, as Figure 9 shown, the cam 5142 and the first link 508 are drivingly connected through a cam follower 5144; the axle 51421 of the cam 5142 is arranged longitudinally, an annular cam groove 51422 is provided on one side surface of the cam 5142, and the axle 51421 of the cam 5142 is eccentrically arranged within the ring formed by the cam groove 51422; the cam follower 5144 is located on the lateral side of the axle 51421 of the cam 5142, one end of the cam follower 5144 is fixedly connected to the first link 508, and the other end of the cam follower 5144 is slidably limited within the cam groove 51422. When the cam 5142 rotates, the cam follower 5144 slides within the cam groove 51422 and reciprocates laterally, thereby driving the first link 508 to reciprocate laterally. It should be noted that in this embodiment, the cam 5142 is an eccentric wheel, the cam groove 51422 is circular, and the axle 51421 of the eccentric wheel is eccentrically arranged within the ring formed by the cam groove 51422. Compared with cams 5142 of other shapes, using an eccentric wheel drive can make the reciprocating motion of the first link 508 more stable laterally.
