Description

Technical Field

[0001] The utility model relates to the technical field of spinning devices, in particular to a device for preparing electrostatic spinning oriented fibers. Background Art

[0002] Electrospinning is a preparation technology that stretches polymer solution or melt from a nozzle into fibers under the action of an electrostatic field. The basic principle is that under the action of an external electric field, the polymer solution or melt is ejected from the nozzle by electrostatic force to stretch it into fibers. It has a wide range of applications in various fields.

The utility model uses a spiral heating tube arranged on the nozzle. When condensation occurs in the nozzle, the spiral heating tube provides high-temperature heat to eliminate the condensation phenomenon on the nozzle. Compared with manual processing, the elimination effect is good and the speed is fast; because an anti-static component is arranged on the driving component, the driving component can be effectively prevented from being interfered by static electricity.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 , the utility model provides an embodiment: an electrostatic spinning oriented fiber preparation device, including a box body 1, a slide rail 2 is fixedly connected to the top of the inner wall of the box body 1, a sliding block 6 is slidably connected to the middle of the slide rail 2, an electrostatic spinning nozzle 5 is fixedly connected to the bottom of the sliding block 6, a threaded rod 4 is rotatably connected inside the slide rail 2, the sliding block 6 is threadedly connected to the middle of the threaded rod 4, a motor 3 is fixedly connected to the left side of the box body 1, the output end of the motor 3 is fixedly connected to the left side of the threaded rod 4, a slide plate 10 is slidably connected inside the box body 1, and the top of the slide plate 10 is fixedly connected to left and right opposite support frames 12, the right side of the right support frame 12 is fixedly connected to a motor 2 11, a rotating shaft 13 is rotatably connected between the two support frames 12, the output end of the motor 2 11 is fixedly connected to the right side of the rotating shaft 13, a transmission component is arranged on the top of the box body 1, the left and right sides of the slide rail 2 are fixedly connected to a limiting block 16, and the sliding block 6 is arranged between the two limiting blocks 16.

[0033] The motor 2 11 drives the rotating shaft 13 to rotate between the two support frames 12, so that the electrospinning ejected from the electrospinning nozzle 5 is wound around the rotating shaft 13, and the motor 1 3 drives the threaded rod 4 to rotate inside the slide rail 2. When the threaded rod 4 rotates, the thread drives the sliding block 6 to slide left and right in the middle of the slide rail 2. Due to the sliding of the sliding block 6, the electrospinning nozzle 5 will also move left and right when ejecting. When the rotating shaft 13 rotates to receive the electrospinning, the movement of the electrospinning nozzle 5 itself expands the collection coverage, so that the electrospinning is wound more evenly to avoid accumulation in a certain place. The two limit blocks 16 are used to limit the sliding block 6 when it slides left and right to avoid excessive sliding.

[0034] Reference Figure 2 and Figure 3 The transmission component includes a storage box 7 and an output pump 8. The storage box 7 is fixedly connected to the top rear side of the box body 1. The output end of the output pump 8 is fixedly connected to a transmission tube 9. The transmission tube 9 passes through the box body 1 and is fixedly connected to the rear side of the electrospinning nozzle 5. A rotating cover 30 is rotatably connected to the top of the storage box 7, and an observation port 31 is provided on the right side of the front end of the storage box 7.

[0035] Start the output pump 8 to extract the raw material solution or melt in the storage box 7 and transfer it to the transfer pipe 9. After the transfer pipe 9 passes through the box body 1, the solution or melt is transferred to the electrospinning nozzle 5 and sprayed out. The remaining capacity in the storage box 7 can be observed through the observation port 31. When replenishment is needed, the rotating cover 30 is rotated to open the storage box 7, so as to facilitate the filling of the raw material solution or melt for replenishment.

[0036] Reference Figure 2 , Figure 4 and Figure 5 The bottom of the inner wall of the box body 1 is slidably connected with a front-to-back opposite slide bar 26, the bottom of the slide plate 10 is slidably connected with a front-to-back opposite slide bar 1, a left-to-right opposite movable frame 25 is rotatably connected between the two slide bars 1 24 and the two slide bars 26, a bidirectional screw 28 is threadedly connected between the two slide bars 26, a motor 3 27 is fixedly connected to the bottom of the front end of the box body 1, the output end of the motor 3 27 is fixedly connected to the front end of the bidirectional screw 28, the bottom of the inner wall of the box body 1 is fixedly connected with left-to-right opposite limit blocks 20, the tops of the two limit blocks 20 are fixedly connected with front-to-back opposite slide bars 21, and the tops of the multiple slide bars 21 are fixedly connected with multiple limit blocks 3 22, recessed holes 23 are opened at the four corners of the top of the slide plate 10, and the multiple limit blocks 3 22 are respectively slidably connected inside the multiple recessed holes 23, and a limiting ring 29 is fixedly connected to the middle of the bidirectional screw 28.

[0037] The limiting ring 29 is driven to rotate by the motor three 27. When the limiting ring 29 rotates, the thread drives the two slide bars 26 to slide on the bottom of the inner wall of the box body 1 and approach each other. At this time, the two movable frames 25 are rotated and unfolded by the approach of the two slide bars 26, and drive the two slide bars 1 24 to approach each other and drive the slide plate 10 to slide upward. At the same time, multiple recessed holes 23 slide upward through multiple slide rods 21 until the rotating shaft 13 is limited by the limiting block three 22. At this time, the rotating shaft 13 will directly contact the electrostatic spinning nozzle 5 and receive the electrostatic spinning initially ejected. After the electrostatic spinning sticks to the rotating shaft 13, the bidirectional screw 28 is rotated in the opposite direction by the motor three 27, so that the two slide bars 26 are moved away from each other. At this time, the two movable frames 25 will rotate and fold, so that the two slide bars 1 24 are moved away from each other and drive the slide plate 10 to slide downward until it is against the limiting block 20, collect the electrostatic spinning on the rotating support frame 12, and limit the two slide bars 26 by the limiting ring 29 to avoid excessive sliding and approaching.

[0038] Reference Figure 1 and Figure 3 The front end of the top of the box body 1 is fixedly connected with an electrostatic generator 14 , the front end of the electrostatic generator 14 is provided with a connecting line 15 , and the connecting line 15 is fixedly connected to the front end of the electrostatic spinning nozzle 5 .

[0039] The electrostatic generator 14 is connected to the electrostatic spinning nozzle 5 through the sliding block 6, so that the electrostatic spinning nozzle 5 generates an electric field force on the solution or melt when it is ejected to stretch it into fibers, which is convenient for collecting and winding the electrostatic spinning.

[0040] Reference Figure 1 and Figure 2 The middle parts of the left and right sides of the box body 1 are fixedly connected with fixed blocks 17, the front ends of the two fixed blocks 17 are slidably connected with sliding drawers 18, the opposite sides of the two fixed blocks 17 are fixedly connected with push handles 19, and the bottom of the box body 1 is fixedly connected with uniformly distributed universal wheels 32.

[0041] Hold the handle at the front end of the sliding drawer 18 and pull it out to store the wound electrospun fibers or take them out for use. Hold and push the push handle 19 on one side to move the entire box 1 through the rolling of multiple universal wheels 32.

[0042] Working principle: When the electrospinning oriented fiber preparation device is used, the motor 3 27 drives the bidirectional screw 28 to rotate and drives the two slide bars 26 to slide close to each other, so that the two movable frames 25 rotate and open and drive the two slide bars 1 24 to slide close to each other, and the slide plate 10 is slid upward until it hits the limit block 3 22. At this time, the rotating shaft 13 will contact the electrospinning nozzle 5, and the solution or melt in the storage box 7 is extracted by the output pump 8 and transmitted to the electrospinning nozzle 5 through the transmission pipe 9 for spraying. The rotating shaft 13 contacts the electrospinning nozzle 5 and receives the electrospinning initially sprayed, and then sticks to the electrospinning through the electric Machine three 27 drives the bidirectional screw 28 to rotate in opposite directions and drives the two slide bars 26 to slide away from each other through threads, so that the two movable frames 25 rotate and fold and drive the two slide bars 1 24 to slide away from each other, drive the slide plate 10 to slide downward, and drive the rotating shaft 13 to rotate in the two support frames 12 through motor two 11, and the subsequent electrostatic spinning is wound, and the threaded rod 4 is driven to rotate through motor one 3. The threaded rod 4 drives the sliding block 6 to slide left and right in the middle of the slide rail 2, and at the same time drives the electrostatic spinning nozzle 5 to move when spraying, so that the rotating shaft 13 expands the area of ​​electrostatic spinning winding to avoid accumulation in a certain place.
