Description

Technical Field

[0001] This utility model relates to a feed roller based on electrospinning, specifically a feed roller based on electrospinning, belonging to the field of electrospinning technology. Background Technology

[0002] Electrospinning is a technology that uses a high-voltage electrostatic field to prepare nanofibers. By spraying a spinning solution, a spinning layer is formed under the action of electrostatics and coated onto a base layer. Electrospinning technology has great potential in fields such as biomedicine, environmental protection, and energy due to its simplicity, efficiency, low cost, and ability to prepare nanofibers. In electrospinning, a feed roller is used to transport the base material to be coated with the filament layer, such as rubber cloth or metal mesh cloth that receives the filaments, so as to carry out continuous spinning.

[0003] In existing feed rollers, the take-up roller increases in diameter as more base material is covered. To ensure the conveying speed of the base material, the rotation speed of the take-up roller needs to be changed. The current method of controlling the rotation speed of the take-up roller is to measure the diameter change with a laser rangefinder and then control the variable speed motor to change the rotation speed of the take-up roller. This method is costly and the speed control is complex. When the laser rangefinder or the variable speed motor malfunctions, the speed cannot be accurately controlled, and the probability of error is relatively high.

[0004] Therefore, a feed roller based on electrospinning is proposed here. Utility Model Content

[0005] This invention proposes a feed roller based on electrospinning to solve the problem that the speed control method of the take-up roller in the feed roller in the prior art is relatively complex and costly.

[0006] This utility model is achieved through the following technical solution: a feeding roller based on electrospinning, including a fixed frame, a winding assembly is provided inside the fixed frame, the winding assembly includes a winding roller and a first rotating shaft rotatably connected to the inner wall of the fixed frame, a first locking block is fixed at one end of the first rotating shaft near the winding roller, and the first locking block is adapted to the winding roller.

[0007] The fixed frame is equipped with a feeding assembly, which includes a feeding roller, a third rotating shaft rotatably connected to the inner wall of the fixed frame, and a fourth rotating shaft that passes through the fixed frame and is slidably connected to the fixed frame.

[0008] The inner wall of the fixed frame is rotatably connected to a drive roller and an auxiliary roller. The inside of the fixed frame is provided with a clamping assembly, which includes a movable plate. Two fixed tubes are fixed on the upper surface of the movable plate. Fixed rods are slidably connected to the inner walls of the two fixed tubes. Auxiliary wheels are fixed to the top ends of the two fixed rods.

[0009] A transmission assembly is provided on the outside of the fixed frame. The transmission assembly includes a U-shaped frame fixed to the outer surface of the fixed frame and a first docking seat. The first docking seat is fixed to the end of the first rotating shaft away from the take-up roller. A rotating tube is rotatably connected to the inner wall of the U-shaped frame. A sliding rod is slidably connected to the inner wall of the rotating tube. A second docking seat is fixed to the end of the sliding rod near the first docking seat. The second docking seat is adapted to the first docking seat. A second spring is fixed to the end of the rotating tube near the first docking seat. The end of the second spring away from the rotating tube is fixed to the outer surface of the second docking seat. A driven pulley is fixed to the end of the rotating tube away from the first docking seat. A driving pulley is fixed to the end of the driving roller near the driven pulley. The driven pulley and the driving pulley are connected by belt drive.

[0010] Preferably, the winding assembly further includes a first mounting plate that is bolted to the outer surface of the fixed frame. A second rotating shaft is rotatably connected to the outer surface of the first mounting plate. A second locking block is fixed to the end of the second rotating shaft away from the first mounting plate. The second locking block is adapted to the winding roller. The second locking block and the first locking block can be inserted into the winding roller at the same time to install and fix the winding roller.

[0011] Preferably, a third locking block is fixed at one end of the third rotating shaft near the feeding roller, and the third locking block is adapted to the feeding roller. A fourth locking block is fixed at one end of the fourth rotating shaft near the feeding roller, and the fourth locking block is adapted to the feeding roller. A second mounting plate is rotatably connected at one end of the fourth rotating shaft away from the feeding roller. The second mounting plate is mounted on the outer surface of the fixing frame by bolts. When the second mounting plate is removed and moved outward, the fourth locking block can be pulled out of the feeding roller.

[0012] Specifically, a first spring is fixed to the bottom surface of each of the two auxiliary wheels, and the bottom ends of the two first springs are fixed to the upper surface of the moving plate. The first springs are always kept in a compressed state, ensuring that the auxiliary wheels and the driving roller can clamp the base material when they cooperate to hold it.

[0013] Furthermore, two symmetrical anti-detachment sliders are fixed to the outer surfaces of both fixing rods. The anti-detachment sliders are slidably connected to the inner wall of the fixing tube. Two grooves adapted to the anti-detachment sliders are opened on the fixing tube. The sliding of the anti-detachment sliders in the grooves of the fixing tube can prevent the fixing rods from detaching from the fixing tube.

[0014] Furthermore, two guide rods are fixed to the bottom surface of the movable plate. Both guide rods pass through the fixed frame and are slidably connected to the fixed frame. The guide rods guide the movement of the movable plate.

[0015] Furthermore, a screw is rotatably connected to the bottom surface of the movable plate. The screw passes through the fixed frame and is threadedly connected to the fixed frame. The movable plate can be moved by rotating the screw.

[0016] This invention provides a feed roller based on electrospinning, which has the following beneficial effects:

[0017] This electrospinning-based feeding roller, through the setup of clamping and transmission components, can control the conveying speed of the base material relatively simply and accurately. Compared to the existing method of measuring diameter changes with a laser rangefinder and then controlling the variable speed motor to change the rotation speed of the take-up roller, the equipment cost is lower, and it is simpler and less prone to errors.

[0018] The electrospinning-based feed roller, through the setup of the take-up assembly and the feed assembly, allows for easy replacement of the take-up roller and the feed roller when the bolts on the first and second mounting plates are loosened. This removes the first and second mounting plates and moves the second and fourth rotating shafts outward, enabling the second locking block to be pulled out of the take-up roller and the fourth locking block to be pulled out of the feed roller. Then, new take-up rollers and feed rollers can be replaced. Conversely, the installation of the take-up roller and the feed roller can be completed. Attached Figure Description

[0034] Please refer to the following carefully.

When the second mounting plate 36 is removed and moved outward, the fourth locking block 35 can be pulled out of the feeding roller 31.

[0036] Please refer to the following carefully. Figure 2 and Figure 6 The inner wall of the fixed frame 1 is rotatably connected to a drive roller 6 and an auxiliary roller 7. The fixed frame 1 is equipped with a clamping assembly 4, which includes a movable plate 41. Two fixed tubes 42 are fixed on the upper surface of the movable plate 41. Fixed rods 43 are slidably connected to the inner walls of the two fixed tubes 42. Auxiliary wheels 44 are fixed at the top of the two fixed rods 43. The base material is clamped between the drive roller 6 and the auxiliary wheel 44. At this time, the fixed tubes 42 and the fixed rods 43 are in the shortest possible state to ensure that the auxiliary wheel 44 will not shake.

[0037] Please refer to the following carefully. Figure 6 The bottom surfaces of the two auxiliary wheels 44 are each fixed with a first spring 45. The bottom ends of the two first springs 45 are fixed to the upper surface of the moving plate 41. The first springs 45 are always kept in a compressed state, ensuring that the auxiliary wheels 44 and the driving roller 6 can clamp the base material when they cooperate to hold it.

[0038] Please refer to the following carefully. Figure 6 Two symmetrical anti-detachment sliders 46 are fixed on the outer surface of each of the two fixing rods 43. The anti-detachment sliders 46 are slidably connected to the inner wall of the fixing tube 42. Two grooves adapted to the anti-detachment sliders 46 are opened on the fixing tube 42. The sliding of the anti-detachment sliders 46 in the grooves of the fixing tube 42 can prevent the fixing rods 43 from detaching from the fixing tube 42.

[0039] Please refer to the following carefully. Figure 6 Two guide rods 47 are fixed on the bottom surface of the movable plate 41. Both guide rods 47 pass through the fixed frame 1 and are slidably connected to the fixed frame 1. The guide rods 47 guide the movement of the movable plate 41.

[0040] Please refer to the following carefully. Figure 6 The bottom surface of the movable plate 41 is rotatably connected to a screw 48, which passes through the fixed frame 1 and is threadedly connected to the fixed frame 1. The movable plate 41 can be moved by rotating the screw 48.

[0041] Please refer to the following carefully. Figure 1 , Figure 4 and Figure 5 A transmission assembly 5 is provided on the outside of the fixed frame 1. The transmission assembly 5 includes a U-shaped frame 51 fixed to the outer surface of the fixed frame 1 and a first docking seat 52. The first docking seat 52 is fixed to the end of the first rotating shaft 22 away from the take-up roller 21. The inner wall of the U-shaped frame 51 is rotatably connected to a rotating tube 53. A sliding rod 54 is slidably connected to the inner wall of the rotating tube 53. A second docking seat 55 is fixed to the end of the sliding rod 54 near the first docking seat 52. The second docking seat 55 is adapted to the first docking seat 52. The rotating tube 53 is located near the first docking seat 52. A second spring 56 is fixed at one end. The second spring 56 is always in a compressed state to ensure that the second docking seat 55 is always subjected to a force close to the first docking seat 52. The end of the second spring 56 away from the rotating tube 53 is fixed to the outer surface of the second docking seat 55. When the second docking seat 55 docks with the first docking seat 52, the second docking seat 55 can drive the first docking seat 52 to rotate. When the first docking seat 52 is resisted, the second docking seat 55 will rotate and separate from the first docking seat 52. At the same time, the second docking seat 55 compresses the second spring 56.

[0042] Please refer to the following carefully. Figure 5 and Figure 6 A driven pulley 57 is fixed at one end of the rotating tube 53 away from the first docking seat 52, and a driving pulley 58 is fixed at one end of the drive roller 6 near the driven pulley 57. The driven pulley 57 and the driving pulley 58 are connected by belt drive. A motor that provides power for the rotation of the driving pulley 58 is provided on the fixed frame 1.

[0043] In use, the following steps are taken: The feeding roller 31, containing the base material to be spun, is fixed between the third clamping block 33 and the fourth clamping block 35. One end of the base material passes through the bottom of the auxiliary roller 7, between the drive roller 6 and the auxiliary wheel 44, and is wound onto the take-up roller 21. By rotating the screw 48, the moving plate 41 moves upward, clamping the base material between the drive roller 6 and the auxiliary wheel 44. At this time, the fixing tube 42 and the fixing rod 43 are at their shortest possible positions, and the first spring 45 is compressed, ensuring the base material is stably clamped by the drive roller 6 and the auxiliary wheel 44. Then, the motor on the fixing frame 1 rotates, causing the drive pulley 58 and the drive roller 6 to rotate. The drive roller 6 drives the base material to be conveyed, and the base material undergoes electrostatic spinning below the drive roller 6 and the auxiliary roller 7. Under the transmission action of the drive pulley 58 and the driven pulley 57, the rotating tube 53 rotates accordingly, and through the sliding rod 54, the second docking seat 55, and the first docking seat 52, the first… The rotating shaft 22 and the take-up roller 21 rotate. The take-up roller 21 takes up the base material after spinning. As the combined diameter of the take-up roller 21 and the base material increases, the take-up roller 21 can no longer rotate at its original speed due to the tension of the base material. The first docking seat 52 and the second docking seat 55 separate, causing the sliding rod 54 to slide into the rotating tube 53, and the second spring 56 is compressed. When the base material between the take-up roller 21 and the drive roller 6 is loose, the second docking seat 55 is reinserted into the first docking seat 52 under the elastic force of the second spring 56. The second docking seat 55 drives the take-up roller 21 to continue rotating, thereby ensuring that the take-up roller 21 can take up the base material. At the same time, the rotation of the take-up roller 21 does not affect the conveying speed of the base material. The conveying speed of the base material is consistent with the rotation of the drive roller 6. This device can control the conveying speed of the base material in a relatively simple and accurate manner. The equipment cost is low, and it is relatively simple and not prone to errors.
