Description

Technical Field

[0001] The invention relates to the technical field of electrostatic spinning machines, and in particular to an electrostatic spinning machine which is convenient for clearing blockage of a spinning head. Background Art

[0002] An electrospinning machine is a device used to manufacture nanofibers. It uses electrostatic attraction to stretch a polymer solution or melt at the nozzle to form fibers. This technology is widely used in materials science, textile engineering, biomedical engineering and other fields. The basic principle of electrospinning is to use a high-voltage power supply to apply an electrostatic field to the solution or melt nozzle, so that the ejected polymer flow is stretched into filaments by the electrostatic force. As the polymer solution or melt flies in the air, the solvent gradually evaporates, causing the polymer chains to gradually solidify and eventually form nanofibers.

[0003] In the process of using electrospinning machines for nanofiber production, it is common for the spinning head to frequently become clogged. This blockage may be caused by a variety of factors, such as inappropriate viscosity of the solution or melt, particles or bubbles in the solution, too small inner diameter of the nozzle, improper adjustment of operating conditions, etc. These factors may cause the polymer solution to form coagulated blocks or gel-like substances during the injection process, and eventually clog the nozzle. When the spinning head is clogged, the current common solution usually requires stopping the machine, removing the spinning head, and then manually cleaning it. This process may involve using sharp tools or high-pressure water guns to remove the blockage. This cleaning process is relatively time-consuming and complicated to operate. Summary of the invention

[0004] The purpose of the present invention is to provide an electrospinning machine that is easy to clear a spinning head. It solves the problem that when the spinning head is blocked, the current common solution usually requires stopping the machine, removing the spinning head, and then manually cleaning it. This process may involve using sharp tools or high-pressure water guns to clear the blockage, and this cleaning process is relatively time-consuming and complicated to operate.

[0005] The specific application is as follows: It comprises a frame body, a feeding assembly is arranged in the frame body, a spinning head body is connected to one side of the feeding assembly, a winding assembly is connected to the frame body, a control console is connected to the frame body, a cleaning device is provided throughout the frame body, a blowing device is connected to the frame body, the cleaning device comprises a fixed block, a double winch is connected to the fixed block, two ropes are wound around the double winch, a sliding sleeve is arranged on the outer sleeve of the rope, one end of the two ropes are connected to the same shell body, two through holes are arranged in the shell body, a nozzle is connected to one side of the shell body, a hose is connected to one side of the nozzle, an air compressor is connected to one end of the hose, a baffle is connected to the other side of the shell body, a sliding rod is slidably connected to the baffle, a circular plate is connected to one side of the sliding rod, a buffer plate is connected to the other side of the sliding rod, and a pull-back spring is arranged on the outer sleeve of the sliding rod.

[0006] As a preferred technical solution of the present application, the fixing block is connected to the frame, and the sliding sleeve is connected through the frame.

[0007] As a preferred technical solution of the present application, the nozzle corresponds to the position of the through hole, the air compressor is connected in the frame, and the feeding assembly is clamped in the spinning head body.

[0008] As a preferred technical solution of the present application, one end of the return spring is connected inside the circular plate, and the other end of the return spring is connected inside the baffle.

[0009] As a preferred technical solution of the present application, the blowing device includes a fixing plate, the fixing plate is connected in the frame, the front of the fixing plate is connected to a motor, and one side of the motor is connected to a reciprocating screw.

[0010] As a preferred technical solution of the present application, the reciprocating screw is rotatably connected in a fixed plate, and a threaded cap is disposed on the outer sleeve of the reciprocating screw.

[0011] As a preferred technical solution of the present application, the threaded cap is overlapped on the front side of the fixing plate, and an air pump is connected to the threaded cap.

[0012] As a preferred technical solution of the present application, the output end of the air pump is connected to a pipeline, and one end of the pipeline is connected to a nozzle.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. Through the arrangement of fixed blocks, double winches, ropes and other parts, when multiple spinning head bodies need to be cleared, the needle tube in the feeding assembly is separated from the spinning head body, and then the double winch is started. At this time, the shell applies tension to the two ropes, and the tension drives the ropes to move through the sliding sleeve. Then, when the shell falls outside the spinning head body, it is confirmed that the through hole corresponds to the position of the spinning head body. At this time, the air compressor is started, and the air compressor sprays the air flow from the nozzle after passing the hose. Then the air flow impacts the inside of the spinning head body. At this time, the blockage in the spinning head body is blown to the buffer plate. At this time, the impact force drives the buffer plate to move, and the buffer plate drives the slide rod to slide. Then the pull-back spring applies elastic force to the circular plate, and the elastic force drives the circular plate to move. Then the buffer plate is quickly reset, which solves the problem that when the spinning head is blocked in the prior art, the common solution usually requires stopping the machine, removing the spinning head, and then manually cleaning. This process may involve using sharp tools or high-pressure water guns to remove the blockage. This cleaning process is relatively time-consuming and complicated to operate. 2. Through the setting of the fixed plate, motor, air pump and other components, it is achieved that when the processing is completed and the waste inside the frame needs to be cleaned, the motor and the air pump are started at this time, and the motor starts to drive the reciprocating screw to rotate. When the reciprocating screw rotates, the threaded cap moves back and forth horizontally. Driven by the reciprocating screw, the threaded cap moves along the spiral line of the thread. At the same time, as the threaded cap moves, it also drives the air pump to move together. When the air pump moves with the threaded cap, the air pump will generate an airflow through a pipe to the nozzle. The nozzle is a jet device that ejects the airflow at a certain speed and direction. In this scenario, the airflow is sprayed toward the waste at the bottom of the frame, and the airflow exerts force on the waste to make it reciprocate along the length of the frame. The effect of this reciprocating blowing is to push the waste in the frame to one side of the frame. In this way, the waste in the frame is effectively concentrated on one side of the frame, making the subsequent cleaning work more convenient and efficient. In this process, the waste is blown to one side of the frame, which greatly reduces the difficulty and intensity of the cleaning work, and solves the problem in the prior art that the waste is accumulated in a large processing area and is inconvenient to clean; BRIEF DESCRIPTION OF THE DRAWINGS

One end of the two ropes 603 is connected to the same shell 605, and two through holes 609 are provided in the shell 605. A nozzle 606 is connected to one side of the shell 605, and a hose 607 is connected to one side of the nozzle 606. One end of the hose 607 is connected to an air compressor 608. A baffle 610 is connected to the other side of the shell 605, and a slide bar 612 is slidably connected in the baffle 610. A circular plate 611 is connected to one side of the slide bar 612, and a buffer plate 614 is connected to the other side of the slide bar 612. A pull-back spring 613 is provided on the outer sleeve of the slide bar 612.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the fixed block 601 is connected to the frame 1, the sliding sleeve 604 is connected through the frame 1, the nozzle 606 corresponds to the position of the through hole 609, the air compressor 608 is connected in the frame 1, the feeding assembly 2 is clamped in the spinning head body 3, one end of the return spring 613 is connected in the circular plate 611, and the other end of the return spring 613 is connected in the baffle 610. By setting up the feeding component 2, the feeding component 2 specifically refers to a peristaltic pump, a pusher, a heater and other components. The pump can transport the solution through mechanical action to provide a stable flow rate and flow rate, while the peristaltic pump drives the solution to flow by peristalsis back and forth through a small pump column, and can also accurately control the solution delivery rate. The pusher is used to extract the solution from the container and transport it to the spinneret. This device usually has a slender tip to ensure that the solution can be pulled out evenly to form a stable jet; by setting up the pull-back spring 613, when the buffer plate 614 is not impacted, the pull-back spring 613 applies an elastic force to the circular plate 611 to keep it stable. When the buffer plate 614 is impacted, the pull-back spring 613 applies an elastic force to the circular plate 611, and the elastic force drives the circular plate 611, the slide rod 612 and the buffer plate 614 to move, so that they can be quickly reset.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the blowing device 7 includes a fixing plate 71, the fixing plate 71 is connected in the frame 1, the front of the fixing plate 71 is connected to a motor 72, one side of the motor 72 is connected to a reciprocating screw 73, the reciprocating screw 73 is rotatably connected in the fixing plate 71, and the reciprocating screw 73 is provided with a threaded cap 74 on its outer sleeve. By setting the threaded cap 74 and the fixing plate 71, the threaded cap 74 cooperates with the fixing plate 71, so that the threaded cap 74 has a unique rectangular shape. On one side of this rectangle, a structure that closely matches the fixing plate 71 is designed. When the threaded cap 74 moves along a straight path, the rectangular surface is in close contact with the fixing plate 71 to form a stable connection. Such a design ensures that the threaded cap 74 will not spin or rotate during the movement. This connection mechanism is very useful in mechanical devices because it provides a simple and effective locking method to prevent the accidental rotation of the parts during the movement.

[0023] like Figure 5 ,and Figure 6As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a threaded cap 74 is overlapped on the front of the fixing plate 71, an air pump 75 is connected to the threaded cap 74, a pipe 76 is connected to the output end of the air pump 75, and a nozzle 77 is connected to one end of the pipe 76. By setting the nozzle 77 and the frame 1, the nozzle 77 cooperates with the frame 1, so that the nozzle 77 can blow air into the inside of the frame 1, which helps to stir the waste in the frame 1 and push it to one side of the frame 1. This process simplifies the cleaning work because the waste is now concentrated in one place and is easier to be removed. This blowing method improves the cleaning efficiency, reduces the cleaning time, and can reduce the damage to the frame 1 because there is no need to perform severe manual cleaning on the inside of the frame 1.

[0024] Specifically, when the electrospinning machine technology is working / in use: when the multi-spinning head body 3 needs to be cleared, the needle tube in the feeding assembly 2 is separated from the spinning head body 3, and then the double winch 602 is started. At this time, the shell 605 applies tension to the two ropes 603, and the tension drives the ropes 603 to move through the sliding sleeve 604. Then, when the shell 605 falls outside the spinning head body 3, it is confirmed that the through hole 609 corresponds to the position of the spinning head body 3. At this time, the air compressor 608 is started, and the air compressor 608 passes the airflow through the hose 607 and then sprays it from the nozzle 606. Then the airflow impacts the inside of the spinning head body 3. At this time, the blockage in the spinning head body 3 is blown to the buffer plate 614. At this time, the impact force The buffer plate 614 is driven to move, and the buffer plate 614 drives the slide bar 612 to slide, and then the pull-back spring 613 applies elastic force to the circular plate 611, and the elastic force drives the circular plate 611 to move, and then the buffer plate 614 is quickly reset. When the processing is completed, when it is necessary to clean the waste inside the frame 1, the motor 72 and the air pump 75 are started at this time, and the motor 72 drives the reciprocating screw rod 73 to rotate, and the reciprocating screw rod 73 drives the threaded cap 74 to move, and the threaded cap 74 drives the air pump 75 to move.
