Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a liquid supply device using a needle-free liquid coating method. Background Technology

[0002] With the development of the times, electrospinning technology is a unique process that uses high-voltage electrostatic field force to prepare ultrafine fibers. Its basic process is to carry a high-voltage charge of thousands to tens of thousands of volts on a polymer solution or melt. Under the action of the electric field, a Taylor cone is formed on the surface of the droplet and a jet is excited. The jet undergoes violent whipping unstable motion in the electric field, while the solvent evaporates rapidly. Finally, it solidifies and is deposited on the receiving device to form a fiber membrane with a diameter between tens of nanometers and several micrometers.

[0003] Currently, for industrialization, improving efficiency and increasing production capacity are the most important. Traditional single-needle spinning is extremely inefficient and prone to clogging, making it completely unable to meet mass production needs. Multi-needle arrays increase output by increasing the number of needles, but at the same time, they also have serious electric field interference problems, resulting in uneven fibers and high maintenance complexity. While needleless spinning solves the clogging problem and significantly improves efficiency, its fiber diameter distribution is relatively wide, and uniformity control remains a challenge. In addition, the solution utilization rate is low. Among these spinning technologies, needleless spinning is the most suitable, but its low solution utilization rate leads to reduced production capacity.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a liquid supply device using a needle-free liquid application method to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a liquid supply device for needle-free liquid application, including a liquid supply tank and a horizontally arranged slide fixed to the bottom of the liquid supply tank. A fixed shaft is horizontally fixed inside the liquid supply tank, and the axial direction of the fixed shaft is parallel to the length direction of the liquid supply tank. Multiple bearings are sleeved on the outer arc wall of the fixed shaft and evenly distributed along its axial direction. The top of the outer arc wall of each bearing is frictionally abutted with a horizontal steel wire, and the length direction of the steel wire is perpendicular to the length direction of the fixed shaft.

[0007] Furthermore, vertical fixing plates are snapped at both ends of the steel wire along its axial direction. The two fixing plates are respectively fixed to both ends of the slide table and do not interfere with the movement of the liquid supply tank. A buffer is connected to one end of the steel wire near the two fixing plates along its axial direction. A connecting lock is provided on the fixing plate at the position corresponding to the buffer. A liquid inlet pipe is provided on one side wall of the liquid supply tank along its width direction, and a liquid outlet pipe is provided on the other side wall. A solution flow controller is provided at the connection between the liquid inlet pipe and the liquid supply tank. A control panel is provided on one side wall of the slide table, and the control panel is electrically connected to the slide table.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. By replacing the traditional needle with a bearing to apply the solution to the steel wire, the problem of easy clogging of the traditional needle is avoided while meeting the fiber diameter requirements. This improves spinning efficiency and increases the output of the filament. Each droplet hanging on the steel wire is equivalent to a needle, and the electric field will not be disturbed by hanging multiple droplets at the same time, resulting in a more uniform spinning effect.

[0009] 2. The control panel allows for manual and automatic control of the slide table, enabling adjustments to the coating speed and delay based on actual production needs. This allows control over the size of the droplets coated on the steel wire, while also preventing waste from starting the next coating cycle before the previous coating has been completely spun.

[0012] 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.

[0013] Please see the appendix Figure 1 To be continued Figure 3The present invention provides a liquid supply device for a needle-free liquid application method: including a liquid supply tank 10 and a horizontally arranged slide 11 fixed to the bottom of the liquid supply tank 10. A fixed shaft 12 is horizontally fixed inside the liquid supply tank 10. The axial direction of the fixed shaft 12 is parallel to the length direction of the liquid supply tank 10. Multiple bearings 13 are sleeved on the outer arc wall of the fixed shaft 12 and are evenly distributed along its axial direction. The top of the outer arc wall of each bearing 13 is rubbed against a horizontal steel wire 21. The length direction of the steel wire 21 is perpendicular to the length direction of the fixed shaft 12. Both ends of the steel wire 21 along its axial direction are clamped with vertical fixing plates 20. The two fixing plates 20 are respectively fixed to both ends of the slide table 11 and do not interfere with the movement of the liquid supply tank 10. The ends of the steel wire 21 along its axial direction close to the two fixing plates 20 are respectively connected with buffers 22. The fixing plates 20 are provided with connecting locks at the positions corresponding to the buffers 22. The liquid supply tank 10 has an inlet pipe 14 on one side wall along its width direction and a drain pipe 15 on the other side wall. A solution flow controller is provided at the connection between the inlet pipe 14 and the liquid supply tank 10. A control panel 23 is provided on one side wall of the slide table 11. The control panel 23 is electrically connected to the slide table 11.

[0014] It should be noted that when the slide table 11 moves, due to the friction between the bearing 13 and the steel wire 21, the bearing 13 will be passively rotated, thereby driving the solution in the liquid supply tank 10 to be evenly coated on the steel wire 21 as it moves. Furthermore, the steel wire 21 needs to be kept taut at all times. However, prolonged tautness can cause metal fatigue in the steel wire 21, leading to breakage. Therefore, a buffer 22 is added to alleviate metal fatigue in the steel wire 21 and improve its lifespan. A solution flow controller is provided at the connection between the inlet pipe 14 and the supply tank 10. When the solution reaches the threshold of the supply tank 10, the supply will automatically stop to prevent the solution from overflowing. Similarly, when the solution in the supply tank 10 is low, the solution can be automatically replenished. The control panel 23 facilitates the control of the speed and timing of the slide table 11 moving along the axial direction of the steel wire 21. It can be understood that controlling the coating speed of the steel wire 21 can increase the output to a certain extent. After the solution is coated onto the steel wire 21, the movement of the slide table 11 is temporarily stopped. The next coating is carried out after the solution on the steel wire 21 has been electrospun. This improves the utilization rate of the solution and can make the spinning more uniform to a certain extent.

[0015] Working principle: When the slide table 11 moves, the bearing 13 rotates due to friction with the steel wire 21, which drives the solution in the liquid supply tank 10 to be evenly applied to the steel wire 21. The buffer 22 relieves metal fatigue of the steel wire 21 and improves its service life. The solution flow controller at the liquid inlet pipe 14 can automatically control the liquid supply to prevent overflow or shortage. The control panel 23 makes it easy to control the moving speed and timing of the slide table 11. After applying the solution, the process is paused and resumed after electrospinning is completed, which improves the solution utilization rate and spinning uniformity.
