Technical Field
[0001] This utility model relates to the field of electrospinning, and in particular to an electrospinning solution supply device. Background Technology
[0002] Electrospinning is a nanofiber manufacturing process that involves spinning polymer liquid matrix or melt in a strong electric field to obtain nanofibers. Many factors influence electrospinning, including temperature, humidity, concentration, and liquid supply rate, among which the liquid supply rate is controlled by the liquid supply equipment.
[0003] In existing technologies, the spinning solution in the spinning solution supply device is generally extracted by a pump. However, after extraction, some liquid remains on the inner wall of the liquid supply device and cannot be discharged, making subsequent cleaning quite cumbersome.
[0004] Therefore, it is necessary to propose an electrospinning solution supply device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an electrostatic spinning solution supply device to solve the problem in the prior art that the spinning solution in the supply device is generally extracted by a pump, but after extraction, some liquid remains on the inner wall of the supply device and cannot be discharged, making subsequent cleaning cumbersome.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrostatic spinning solution supply device, comprising a spinning solution cylinder, wherein a lead screw is rotatably connected between the two ends inside the spinning solution cylinder, a movable plate is threadedly fitted on the outside of the lead screw, a first outlet is provided at the bottom of one end of the spinning solution cylinder, and the movable plate is provided with two states, namely a fixed state and a movable state.
[0007] An air bladder is fixed inside the spinning liquid cylinder on the side away from the first outlet. An electromagnet is fixed on the side of the air bladder near the moving plate. A permanent magnet corresponding to the position of the electromagnet is fixed on the moving plate. An air hole is opened on the air bladder.
[0008] Preferably, a motor is fixed to one end of the spinning liquid cylinder away from the first outlet, and the drive shaft of the motor is fixedly connected to one end of the lead screw.
[0009] Preferably, a second outlet is connected to the bottom end of the spinning liquid cylinder near the motor, and a solenoid valve is installed in the second outlet.
[0010] Preferably, an input port is provided on the top of the spinning liquid cylinder near the motor, and when the moving plate is fixed, the input port and the second outlet are respectively located on both sides of the moving plate.
[0011] Preferably, an observation window is provided on the outer side of the spinning solution cylinder along its length, and a support platform is fixed at the lower end of the spinning solution cylinder.
[0012] Preferably, the spinning solution cylinder is cylindrical.
[0013] Preferably, the input port is provided with a threaded cap.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. In the actual operation of this utility model, spinning solution can be input into the spinning solution cylinder through the input port. The spinning solution cylinder can temporarily store the spinning solution. By starting the motor, the motor drives the lead screw to rotate, thereby moving the moving plate towards the first outlet direction, which can drive the temporarily stored spinning solution inside to be discharged. While the moving plate is moving, it can also remove the spinning solution remaining on the inner wall to avoid accumulation.
[0016] 2. In the initial state, the permanent magnet and electromagnet on the moving plate are close to each other, and the magnetic direction of the electromagnet is controlled to attract the permanent magnet. At this time, the moving plate will be attracted to the electromagnet, which will fix the moving plate. After the moving plate squeezes the spinning solution out of the first outlet, the motor rotates in the opposite direction, driving the moving plate to reset, and cleaning the inner wall of the spinning solution cylinder again, so that the residual liquid can be controlled in the space between the moving plate and the air bag.
[0017] 3. Control the direction of the electromagnet's magnetic force and the repulsion between it and the permanent magnet. Under the action of the repulsion force, the air bag will be squeezed. The airflow generated by the air bag can blow between the moving plate and the inner wall of the spinning liquid cylinder, blowing out the waste liquid between the moving plate and the air bag, and discharging it from the second outlet.
[0018] 4. At the same time, the second outlet opens, which can serve as an exhaust channel, and outside air can also enter, which can be used as the gas needed to fill the airbag. Attached Figure Description

[0023] This utility model provides, for example Figs. 1-3 The electrostatic spinning solution supply device shown includes a spinning solution cylinder 1, with a lead screw 8 rotatably connected between the two ends inside the spinning solution cylinder 1, and a movable plate 9 threadedly fitted on the outside of the lead screw 8. To increase the sealing performance, a piston ring can be fixed on the outside of the movable plate 9.
[0024] To address the problem in existing technologies where a pump is typically used to extract the spinning solution from the spinning solution supply device, but some liquid remains on the inner wall of the device after extraction, making subsequent cleaning cumbersome, a first outlet 3 is provided at the bottom of one end of the spinning solution cylinder 1. The moving plate 9 has two states: a fixed state and a moving state. A motor 6 is fixed at the end of the spinning solution cylinder 1 away from the first outlet 3. The drive shaft of the motor 6 is fixedly connected to one end of the lead screw 8. An input port 5 is provided at the top of the spinning solution cylinder 1 near the motor 6.
[0025] In the actual operation of this utility model, spinning solution can be input into the spinning solution cylinder 1 through the input port 5. The spinning solution cylinder 1 can temporarily store the spinning solution. By starting the motor 6, the motor 6 drives the lead screw 8 to rotate, thereby moving the moving plate 9 towards the first outlet 3, which can drive the temporarily stored spinning solution inside to be discharged. While the moving plate 9 is moving, it can also carry away the spinning solution remaining on the inner wall to avoid accumulation.
[0026] An airbag 10 is fixed inside the spinning liquid cylinder 1 on the side away from the first outlet 3. An electromagnet 12 is fixed on the side of the airbag 10 close to the moving plate 9. A permanent magnet corresponding to the position of the electromagnet 12 is fixed on the moving plate 9. An air hole 11 is opened on the airbag 10.
[0027] In the initial state, the permanent magnet and electromagnet 12 on the moving plate 9 are close to each other, and the magnetic direction of the electromagnet 12 is controlled to attract the permanent magnet. At this time, the moving plate 9 will be attracted to the electromagnet 12, which will fix the moving plate 9. After the moving plate 9 squeezes the spinning liquid out of the first outlet 3, the motor 6 rotates in the opposite direction, driving the moving plate 9 to reset, and cleaning the inner wall of the spinning liquid cylinder 1 again, so that the residual liquid can be controlled in the space between the moving plate 9 and the air bag 10.
[0028] At this time, the magnetic direction of the control electromagnet 12 and the permanent magnet repel each other. Under the action of repulsion, the airbag 10 will be squeezed. The airflow generated by the airbag 10 can blow between the moving plate 9 and the inner wall of the spinning liquid cylinder 1, blowing out the waste liquid between the moving plate 9 and the airbag 10, and discharging it from the second outlet 7.
[0029] At the same time, the second outlet 7 opens, which can serve as an exhaust channel, allowing outside air to enter and fill the airbag 10 with the required gas.
[0030] The bottom end of the spinning liquid cylinder 1 is connected to a second outlet 7 near the motor 6, and a solenoid valve 13 is installed in the second outlet 7.
[0031] With the movable plate 9 in a fixed state, the inlet 5 and the second outlet 7 are respectively located on both sides of the movable plate 9. An observation window 4 is provided on the outer side of the spinning liquid cylinder 1 along the length direction. A support platform 2 is fixed at the lower end of the spinning liquid cylinder 1 to facilitate observation of the movement of the liquid inside the spinning liquid cylinder 1.
[0032] The spinning solution cylinder 1 is cylindrical, and the inlet 5 is threaded with a threaded cap.
