[0023] This utility model provides, for example Figures 1-4 The multilayer spinning solution mixing device for electrospinning shown includes a barrel 1, with an inlet pipe and an outlet pipe provided on the side wall of the barrel 1 to realize material feeding and discharging.
[0024] An outer ring 2 is fixedly connected to the top of the barrel 1. An inner ring 3 is provided inside the outer ring 2. An annular groove 4 is formed between the outer ring 2 and the inner ring 3. A rotating ring 5 is provided inside the annular groove 4. The rotating ring 5 rotates between the outer ring 2 and the inner ring 3. In actual use, a ball bearing can be set to cooperate for rotation.
[0025] A protective cover 16 is provided above the rotating ring 5. The inner ring 3 and the outer ring 2 are both fixedly connected to the protective cover 16. The protective cover 16 is provided to fix the position of the inner ring 3, and the whole device forms a multi-layer structure.
[0026] The barrel 1 has a rotating shaft 8 inside, which is rotatably connected to the inner ring 3. The top of the inner ring 3 is fixedly connected to a motor 17, and the rotating shaft 8 is fixedly connected to the drive shaft of the motor 17. A stirring blade 18 is fixedly connected to the rotating shaft 8. The motor 17 drives the stirring blade 18 to rotate through the rotating shaft 8, thereby stirring and mixing the spinning solution raw materials.
[0027] To achieve cleaning of the inside of the barrel 1, a second sliding channel 20 is provided on the rotating shaft 8. The second sliding channel 20 is inclined, and a first support rod 7 is slidably disposed inside the second sliding channel 20. A scraper 6 is fixedly connected to the downward inclined end of the first support rod 7. The scraper 6 is L-shaped. When the first support rod 7 slides downward inside the second sliding channel 20, it will drive the scraper 6 to move synchronously. The vertical part of the scraper 6 is attached to the side wall inside the barrel 1, while the horizontal part of the scraper 6 is attached to the bottom wall inside the barrel 1.
[0028] The motor 17 drives the scraper 6 to rotate via the rotating shaft 8 and the first support rod 7, thereby achieving synchronous cleaning of the inner side wall and bottom wall of the barrel 1, improving the cleaning effect, and the rotating ring 5 rotates inside the ring groove 4.
[0029] During the mixing process, the first support rod 7 is controlled to slide upward inside the second sliding channel 20, so that the scraper 6 will not always stick to the inner wall of the barrel 1, avoiding continuous contact and reducing wear.
[0030] During the mixing process, the first support rod 7 and the scraper 6 can be controlled to move back and forth to mix the raw materials and improve the mixing efficiency.
[0031] A flexible telescopic rod 11 is fixedly connected to the end of the first support rod 7 away from the scraper 6. A second support rod 9 is fixedly connected to the end of the flexible telescopic rod 11 away from the first support rod 7. A circular groove 12 is formed at the end of the first support rod 7 near the second support rod 9. A circular rod 13 is slidably disposed inside the circular groove 12 and is fixedly connected to the second support rod 9. The circular rod 13 and the circular groove 12 improve the stability of the connection between the first support rod 7 and the second support rod 9.
[0032] The rotating ring 5 has a first sliding channel 10 for the second support rod 9 to pass through. The top of the rotating ring 5 is fixedly connected to a bracket 14, and an electric push rod 15 is fixedly connected to the bracket 14. The second support rod 9 is fixedly connected to the telescopic end of the electric push rod 15. The electric push rod 15 and the bracket 14 are both located inside the protective cover 16. The electric push rod 15 drives the second support rod 9, the first support rod 7 and the scraper 6 to move.
[0033] The bottom end of the rotating shaft 8 is provided with a groove 19 that mates with the scraper 6. The horizontal part of the scraper 6 slides inside the groove 19, improving the stability of the connection between the scraper 6 and the rotating shaft 8. After cleaning, the telescopic end of the electric push rod 15 is retracted. When the scraper 6 abuts against the groove 19, the telescopic end of the electric push rod 15 is retracted a small distance, and the elastic telescopic rod 11 is extended. Then, the telescopic end of the electric push rod 15 is quickly extended. Under the restoring force of the elastic telescopic rod 11, the first support rod 7 and the scraper 6 produce a shaking effect. This operation is repeated multiple times to shake off the residual material on the scraper 6 and prevent continuous residue.
