Description

Technical Field

[0001] This utility model relates to the field of spinning and winding technology, specifically to an electrostatic spinning and winding device. Background Technology

[0002] Electrospinning is a special fiber manufacturing process in which a polymer solution or melt is jetted and spun in a strong electric field. Under the influence of the electric field, the droplets at the needle tip change from a spherical shape to a conical shape, and extend from the tip of the cone to obtain fine fiber filaments, thus producing polymer filaments. In typical electrospinning equipment, collecting the fine fiber filaments is achieved by continuously rotating collecting rollers pre-covered with silicone paper.

[0003] In electrospinning production, the fine fibers need to be wound and collected. In actual application of existing winding equipment, it is inconvenient to adjust the height of the collecting roller, which limits the applicability of the collecting roller to electrospinning production equipment. At the same time, the connection between the silicone paper and the collecting roller is mainly achieved by using double-sided tape or glue to stick the ends of the silicone paper together on the collecting roller. The stability of the paper sleeve formed by the ends of the silicone paper is difficult to guarantee during the winding process, which is not conducive to the winding and collection of fine fibers.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 This utility model provides a technical solution: an electrostatic spinning winding device, including a collecting roller 2, a drive motor 8 for driving the collecting roller 2 to rotate, and a support base 1 for supporting the collecting roller 2. Both ends of the collecting roller 2 are provided with an extension shaft 3, which passes through the support base 1 and is slidably connected to it. Support plates are rotatably connected to both extension shafts 3. One support plate is threadedly connected with a threaded post 5, which is rotatably connected to the support base 1. A limit sleeve 15 is fixedly connected to the lower part of the threaded post 5. The rotation of the threaded post 5 is limited on the support base 1 by a pin that matches the limit sleeve 15. A guide post 9 is slidably arranged through the other support plate and is fixedly connected to the support base 1.

[0024] This utility model, through the setting of the threaded column 5, enables the support plate connected to the threaded column 5 to drive the collecting roller 2 and the drive motor 8 to move along the axis of the guide column 9 by rotating the threaded column 5, thereby adjusting the height of the entire collecting roller 2 to meet the application requirements of different production equipment.

[0025] Reference Figure 1As shown, in this embodiment, the support plate includes a first support plate 4 and a second support plate 7. A threaded post 5 is threadedly connected to and passes through the first support plate 4. A drive motor 8 is fixedly mounted on the second support plate 7. Adjustment grooves 11 that are slidably connected to the extension shaft 3 are arranged through the support base 1. By using the first support plate 4 and the second support plate 7, the size of the support plate can be easily selected according to the installation requirements, so as to save the overall manufacturing cost.

[0026] Reference Figure 1 As shown in this embodiment, a scale rod 6 is fixedly installed on the support base 1, and the scale rod 6 passes through the second support plate 7. The scale rod 6 is provided with a value to indicate the current height of the collecting roller 2. With the scale rod 6, it is convenient for personnel to know the height of the entire collecting roller 2 in real time during the adjustment process without the need for additional measuring tools, making the overall adjustment process convenient and quick.

[0027] Reference Figure 2 As shown, in this embodiment, the guide post 9 slides through the second support plate 7, and a support elastic element 10 is sleeved between the support base 1 and the second support plate 7 and outside the guide post 9. The support elastic element 10 can help share the pressure at the threaded connection between the threaded post 5 and the second support plate 7, thus jointly supporting the collecting roller 2 and the drive motor 8. Furthermore, it can, to a certain extent, prevent loosening of the threaded connection between the threaded post 5 and the second support plate 7.

[0028] Reference Figure 5 As shown in this embodiment, the outer surface of the limiting sleeve 15 is evenly distributed with several limiting protrusions 151 in a ring. The support base 1 is provided with limiting grooves 152 that match the limiting protrusions 151. The pin is inserted between the limiting grooves 152 and the two limiting protrusions 151 to limit the entire limiting sleeve 15. By setting the limiting protrusions 151 and the limiting grooves 152, the limiting sleeve 15 and the threaded post 5 can be fixed by a pin, thereby ensuring the stability of the threaded post 5 after adjusting the height of the collecting roller 2, and thus improving the stability of the collecting roller 2 winding and collecting.

[0029] Reference Figure 3 and 4In this embodiment, a fixing sleeve 14 is fixedly connected to the extending shaft 3, and an elastic frame 13 is fixedly connected to the fixing sleeve 14. The outer surface of the collecting roller 2 is provided with a groove 12 that matches the shape of the elastic frame 13. When the elastic frame 13 is located in the groove 12, both ends of the collecting roller 2 are complete cylinders. Through the provided elastic frame 13 and groove 12, when the silicone paper is initially fitted onto the collecting roller 2, the elastic frame 13 can further press and fix the two ends of the silicone paper sleeve, effectively improving the stability of the collecting roller 2 for the silicone paper sleeve installation, thereby improving the stability of the entire winding device for collecting electrostatic spinning.
