Embodiment 1

[0041] Such as figure 1 and image 3 As shown, a rotary spinning head for an electrospinner includes a circular bottom plate 1, a support plate 2, a circular plate 3 and a guide rail 4. Two sets of support plates 2 arranged front and back are installed on the top of the circular bottom plate 1, and two sets of A circular plate 3 is installed on the top of the support plate 2;

[0042] A guide rail 4 is installed on the top of the circular plate 3;

[0043] The outer surface of the guide rail 4 is connected in series with multiple sets of evenly arranged spinning head bodies 5. The spinning head body 5 consists of an upper combined ring 6, a lower combined ring 7, a fixed block 8, a groove 9, a locking nail 10 and a semi-circular Composed of helical gears 11, the bottom of the upper combined ring 6 is equipped with a lower combined ring 7, grooves 9 are arranged on both sides of the top of the lower combined ring 7, and fixed blocks 8 are installed on both sides of the bottom...

Embodiment 2

[0046] Such as figure 1 , Figure 4 and Figure 5 As shown, the outer surfaces of the upper combined ring 6 and the lower combined ring 7 are provided with annular grooves 12, wherein the inner walls of a group of annular grooves 12 are equipped with arc-shaped fitting plates 13, and the bottoms of the arc-shaped fitting plates 13 are equipped with connecting columns 14 , An engaging plate 15 is installed on the bottom of the connecting column 14, a fixing column 16 is installed on one end of the connecting plate 15, and a ring gear 17 is installed on the bottom of the fixing column 16.

[0047] Two groups of support members 18 arranged side by side are installed on the top of the round bottom plate 1, U-shaped plates are installed on the tops of the two groups of support members 18, and the top of the U-shaped plate fits with the bottom of the ring gear 17, and the top of the round bottom plate 1 A servomotor 19 is installed, and the output end of the servomotor 19 is equip...

Embodiment 3

[0050] Such as figure 1 and Figure 6 As shown, the top of the guide rail 4 is equipped with multiple groups of threaded rods 21 evenly arranged in a ring, the outer surfaces of the multiple groups of threaded rods 21 are equipped with connecting collars 22, and the tops of the connecting collars 22 are equipped with tapered push rods 23, And the top of the tapered push rod 23 is attached to the inner wall of the half-ring helical gear 11 .

[0051] Specifically, the inner thread of the connecting collar 22 and the thread provided on the outer surface of the threaded rod 21 can be matched with each other, thereby facilitating detachable assembly between the two. When the top of the tapered push rod 23 is seriously worn, the connecting Collar 22 exerts the rotational force of setting anticlockwise direction, in order to be out of contact between it and threaded rod 21, then facilitates the replacement of another group of new tapered push rods 23, in order to improve oneself to...

Abstract

The rotary spinning head comprises a round bottom plate, supporting plates, a round plate and a guide rail, the top of the round bottom plate is provided with two sets of supporting plates arranged front and back, and the tops of the two sets of supporting plates are provided with the round plate; a guide rail is mounted at the top of the circular plate; the outer surface of the guide rail is connected with a plurality of sets of spinning head bodies which are evenly arranged in series, each spinning head body is composed of an upper combined ring, a lower combined ring, a fixing block, grooves, locking nails and a semi-annular bevel gear, the lower combined ring is installed at the bottom of the upper combined ring, the grooves are formed in the two sides of the top of the lower combined ring, and the locking nails are arranged in the grooves. Fixing blocks are installed on the two sides of the bottom of the upper combination ring. The spinning head body is in a detachable and integrated state, the conical push rod is in a detachable and assembled state, then the spinning head body and the conical push rod are convenient to replace, and meanwhile the spinning head body can conduct annular revolution and pushing rotation on the outer surface of the guide rail, so that nanometer materials sprayed on fiber bundles are in a spiral shape.

Description

technical field [0001] The invention relates to the technical field of spinning heads, in particular to a rotary spinning head for an electrostatic spinner. Background technique [0002] Electrospinning refers to the jet spinning of polymer solution or melt in a strong electric field. Under the action of the electric field, the droplet at the needle will change from spherical to conical, and extend from the tip of the cone to obtain fiber filaments. This method can produce nanoscale diameter polymer filaments. [0003] The defective that existing spinning head exists is: [0004] 1. The patent document CN112501700A discloses a rotary fitting electrospinning device and a spinning method, "The rotary fitting electrospinning device includes an outer hollow cylinder spinneret and an inner hollow cylinder, which are used to inject the spinning solution into The syringe of the inner hollow cylinder, the numerical control micro-injection pump used to control the syringe, the high...
