Description

Technical Field

[0001] This application relates to the field of electrospinning machines, and more specifically, to a liquid supply device for an electrospinning machine. Background Technology

[0002] Electrospinning is a technique for preparing nanofibers. Its principle is as follows: under the influence of an electric field, a Taylor cone forms at the tip of a polymer solution. Subsequently, an electrospinning jet is generated at the tip of the Taylor cone and undergoes complex processes such as stretching under the electric field and solution evaporation, ultimately yielding nanofibers. Nanofibers prepared by electrospinning possess properties such as small diameter and large specific surface area, and have broad application potential in fields such as biomedical materials, water filtration, and battery membranes.

[0003] Current electrospinning machines' liquid supply devices cannot achieve quantitative addition when adding various solutions to the storage tank, resulting in low accuracy in the added solutions and thus affecting product quality.

[0004] Chinese patent application CN202320995233.4 discloses a liquid supply device for an electrospinning machine, including a liquid storage tank and a controller assembly. The liquid storage tank is equipped with several quantitative liquid addition components, each comprising a liquid storage tube, a first piston, a second hydraulic lifting device, a laser rangefinder sensor, a connecting pipe, a liquid addition pipe, and a one-way valve. Based on preset values ​​from the PLC controller and the laser rangefinder sensor, the difference detected by the laser rangefinder sensor multiplied by the inner bottom area of ​​the liquid storage tube equals the amount of solution added to the liquid storage tank. The second hydraulic lifting device is activated to push the piston along the inner wall of the liquid storage tube, propelling the solution through the one-way valve and into the liquid storage tank via the liquid addition pipe. The laser rangefinder sensor detects the piston's movement, thus achieving quantitative liquid addition. When the second hydraulic lifting device is paused, the one-way valve resets to prevent the solution in the liquid addition pipe from flowing back into the liquid storage tube under gravity, improving the accuracy of quantitative liquid addition.

[0005] The above solution also has the following shortcomings: When the liquid in the storage tube is used up, it is not easy to add it in time, which reduces the work efficiency. At the same time, the mixed solution is easy to remain on the inner wall of the storage tank and is not easy to scrape off, which reduces the practicality of the device. Utility Model Content

By providing the spiral blade 160 on the outer ring of the rotating shaft 142, it is possible to facilitate further mixing and to facilitate pushing the solution into the electrospinning machine.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The liquid supply structure 20 includes a support frame 210, a placement frame 220, a clamping assembly 230, two limiting plates 240, a liquid storage tank 250, an inlet pipe 260, an outlet pipe 270, and an L-shaped connecting pipe 280. Several support frames 210 are evenly arranged around the outer ring of the cylinder 110. The placement frame 220 is located within the support frame 210, and the clamping assembly 230 is located within the support frame 210. The two limiting plates 240 and the clamping assembly 230... 0 connection, limiting plate 240 is slidably connected to placement frame 220, liquid storage tank 250 is set inside placement frame 220, two limiting plates 240 are respectively snapped to both sides of liquid storage tank 250, liquid inlet pipe 260 is connected to liquid storage tank 250, liquid outlet pipe 270 is connected to liquid storage tank 250, the outer ring of liquid outlet pipe 270 is attached to the inner wall of L-shaped connecting pipe 280, and the two ends of L-shaped connecting pipe 280 are respectively connected to support frame 210 and cylinder 110.

[0037] The working principle of this liquid supply device for an electrostatic spinning machine is as follows: When using the liquid supply device for an electrostatic spinning machine, the liquid storage tank 250 is placed inside the placement frame 220, so that the outer ring of the outlet pipe 270 is in contact with the inner wall of the L-shaped connecting pipe 280 for easy connection. By rotating the handwheel, the bidirectional screw 231 is rotated, causing the two screw nut pairs 232 and the two limiting plates 240 to move closer together, so that the two limiting plates 240 are engaged with the slots, facilitating the disassembly and assembly of the liquid storage tank 250 and allowing for the installation of an appropriate number of liquid storage tanks 250 according to usage requirements. When not in use, the mutual contact of the two limiting plates 240 effectively prevents dust from entering the L-shaped connecting pipe. The L-shaped connecting pipe 280, through the inlet pipe 260, facilitates timely addition of solution. By opening the solenoid valve 2501, the solution in the storage tank 250 enters the cylinder 110 through the outlet pipe 270 and the L-shaped connecting pipe 280. The motor 141 drives the rotating shaft 142, stirring rod 143 and stirring plate 144 to rotate, which facilitates the mixing of the solution. At the same time, the stirring rod 143 drives the scraper 150 to rotate, which facilitates the scraping of the solution remaining on the inner wall of the cylinder 110, improving the practicality of the device. The spiral blades 160 set on the outer ring of the rotating shaft 142 facilitate further mixing and also facilitate the pushing of the solution into the electrostatic spinning machine.
