Description

Technical Field

[0002] Electrospinning technology is the mainstream technology for manufacturing nanofibers. It has the advantages of low cost, wide range of raw materials, and simple equipment. The nanofiber membranes produced have the characteristics of high porosity, large specific surface area, and excellent mechanical properties. It has broad applications and development prospects in environmental treatment, biomedicine, power batteries and other fields. Existing electrospinning equipment is mostly nozzle type and needleless type. Among them, the needleless type has faster spinning efficiency but has disadvantages such as it is difficult to control the uniformity of fiber diameter. The nozzle type is divided into single-needle nozzle and multi-needle nozzle. Single-needle nozzle is mostly used for experiments and small-scale test production, and multi-needle nozzle is mostly used in major industrial production; therefore, the existing device has a relatively single function. Most of the existing multi-needle nozzles are the same and all needles are uniformly supplied with liquid. All needles are arranged and installed fixedly, which cannot meet the different needle arrangements and needle types required for electrospinning of different materials. Moreover, the needles are installed inside the nozzle, which is inconvenient to replace, clean and disassemble. For this reason, we propose an electrospinning nozzle. Summary of the Invention

[0020] Further, the first liquid inlet bin 2 is fixedly connected with locking lugs 4 around, the common ends of the plurality of locking lugs 4 are fixedly connected with an air cavity plate 1, one side of the air cavity plate 1 is fixedly connected with a plurality of movable pipes 21, each movable pipe 21 is inserted into the protection cylinder 802, and one end of the movable pipe 21 is connected with an air pipe 17, one end of the air pipe 17 is fixedly connected with a threaded head, the threaded head is connected with a shunt head 13, the shunt head 13 is fixedly connected with a flow collecting plug 18 on the outside bottom, the size of the flow collecting plug 18 matches the size of the first spray pipe 8; when the shunt head 13 is fixed through the threaded head and the air pipe 17, the side of the flow collecting plug 18 is in contact with the flow hole; by manually rotating the shunt head 13, the shunt head 13 and the threaded head are tightly locked together, the side of the flow collecting plug 18 is in contact with the flow hole, at this time the liquid accumulation cavity 16 cannot enter the liquid into the first spray pipe 8, when the shunt head 13 is manually loosened, the side of the flow collecting plug 18 is separated from the flow hole, so that the flow hole and the first spray pipe 8 are communicated, the flow collecting plug 18 can clean the inner wall of the first spray pipe 8 during the process of taking out the first spray pipe 8 by rotating the shunt head 13, so as to avoid the blockage of the first spray pipe 8, thereby stabilizing the liquid output of the first spray pipe 8.

Once the Taylor cone is formed, the Taylor cone at the front end of the flow head 13 can be dispersed to prevent the solidified filaments at the front end of the flow head 13 from interfering with each other before drying, thereby affecting the final shape of the solidified filaments and the spraying effect and reducing the spraying quality.

[0022] Further, the edge of the flow head 13 extends upward to have a hammer-shaped top, and a plurality of flow inclined stages 1301 are arranged on the side of the hammer-shaped top of the flow head 13.

After the electric torch 19 is electrified, the liquid droplets on the flow inclined stages 1301 form forward jets, so that there are at least three jets. The jets can be dispersed by the first airflow channel 22 and the second airflow channel 23 to prevent the jets from interfering with each other, the surface of the sprayed object can obtain different degrees of spraying effect, the jets can be refined, and the range of beautification processing of the device can be improved.

[0023] The other side of the air cavity plate 1 is fixedly connected with an air pipe extension pipe 24, the side of the air cavity plate 1 near the air pipe extension pipe 24 is fixedly connected with a first liquid inlet pipe 25, the first liquid inlet pipe 25 penetrates the air cavity plate 1 and one end of the first liquid inlet pipe 25 communicates with the first liquid storage tank 2, the side of the air cavity plate 1 near the first liquid inlet pipe 25 is fixedly connected with a second liquid inlet pipe 26, the second liquid inlet pipe 26 penetrates the air cavity plate 1 and the first liquid inlet pipe 25, and one end of the second liquid inlet pipe 26 communicates with the second liquid storage tank 3.
