Description

Technical Field

[0001] The utility model relates to the field of fiber receiving devices, in particular to a nanofiber receiving roller. Background Art

[0002] Jet spinning refers to a spinning method that uses high-speed hot air flow to directly blow and stretch the polymer solution or melt extruded from the spinneret to solidify it into fibers. After the polymer solution is extruded from the spinneret, it is immediately blown by the high-speed air flow around the nozzle to form ultrafine fibers, which are finally deposited on the surface of the receiving device. There are currently two main types of receiving devices, namely receiving mesh curtains and receiving rollers. Compared with receiving mesh curtains, the orientation of the finished fiber is better when using receiving rollers.

[0003] The patent with publication number CN220183451U discloses an electrospinning receiving device, in which one end of the receiving roller is sleeved on the end of the transmission shaft, and the limit column is pushed by a spring, and the limit column pushes the transmission shaft, and the transmission shaft pushes one end of the receiving roller, so that the other end of the receiving roller is sleeved on the end of the rotating shaft, so that the receiving roller is installed; the receiving roller is pushed toward the direction of the transmission shaft, so that one end of the receiving roller is separated from the end of the rotating shaft, and the receiving roller is disassembled. However, if the receiving roller is large in size, the disassembly process is more laborious. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, method scheme and advantages of the embodiments of the utility model clearer, the method scheme in the embodiments of the utility model is clearly and completely described. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Example 1

[0028] like Figure 1-2As shown, a nanofiber receiving roller comprises a first rotating shaft 1, a second rotating shaft 2, a frame 3, a cylinder 4 and a driving device 5, wherein the driving device 5 is connected to the cylinder 4 through the first rotating shaft 1, and the cylinder 4 is mounted on the frame 3 through the first rotating shaft 1 and the second rotating shaft 2, and the second rotating shaft 2 comprises: an outer tube 21, an elastic member 22 and an inner rod 23; the inner rod 23 is sleeved inside the outer tube 21 and connected to the outer tube 21 through the elastic member 22, and the inner rod 23 is connected to the frame 3; the receiving roller further comprises: a screw mechanism 6, and a reciprocating member 62 of the screw mechanism 6 abuts against the inner rod 23. The screw mechanism 6 comprises: a threaded rod 61, and the threaded rod 61 passes through the reciprocating member 62 and is threadedly connected to the reciprocating member 62.

[0029] In the specific implementation process, the screw mechanism 6 can be driven by a motor, the driving device 5 can also be a rotating motor, and the elastic member 22 can be a spring. The rotating motor can drive the cylinder 4 to rotate so that the nanofibers are deposited on the surface of the cylinder 4. The structure of the first rotating shaft 1 can be referred to Figure 5 As shown, the structure of the cylinder 4 can refer to Figure 6 As shown, the first rotating shaft 1 rotates under the drive of the driving device 5, and then the first rotating shaft 1 drives the cylinder 4 to rotate. The first rotating shaft 1 and the cylinder 4 are simply plugged in and the position of the cylinder 4 is further stabilized by the elastic member 22. There are no screws or bolts between the two, so it is more convenient to disassemble or replace the cylinder 4.

[0030] like Figure 2 As shown, when the receiving roller is working, the spring is in a compressed state. Under the action of the spring's rebound force, the inner rod 23 is inserted into the frame 3, and the outer tube 21 is rotatably connected to the cylinder 4. Preferably, a slideway is provided between the inner rod 23 and the outer tube 21, so that the inner rod 23 can slide in the outer tube 21 while the two will not be displaced relative to each other in the circumferential direction, thereby preventing the connection between the inner rod 23 and the frame 3 from affecting the rotation of the cylinder 4. When the cylinder 4 needs to be replaced or disassembled, the screw mechanism 6 is started, and the threaded rod 61 rotates, so that the reciprocating member 62 moves toward the outer tube 21, pushing the inner rod 23 so that the inner rod 23 is separated from the frame 3, thereby realizing the disassembly of the cylinder 4. The disassembly process does not require manual pushing of the cylinder 4, and the operation is more labor-saving.

[0031] Example 2

[0032] In order to save economic costs, improvements were made based on Example 1, such as Figure 2 As shown, in this embodiment, it includes: a driving gear 7, the driving gear 7 is connected to the first rotating shaft 1, and the first rotating shaft 1 is connected to the bidirectional output shaft of the driving device 5; a driven gear 8, the driven gear 8 is meshed with the driving gear 7, and the driven gear 8 is connected to the threaded rod 61.

[0033] During the specific implementation, the rotation direction of the output shaft of the driving device 5 is opposite when the receiving roller is working normally and when the cylinder body 4 is disassembled. For example, when the output shaft of the driving device 5 rotates in the forward direction, the cylinder body 4 rotates to receive the nanofibers, and at this time, the threaded rod 61 rotates, but the reciprocating member 62 cannot move due to the obstruction of the frame body 3. When the output shaft of the driving device 5 rotates in the reverse direction, although the cylinder body 4 rotates, the nanofibers are no longer received, and at this time, the rotation of the threaded rod 61 will drive the reciprocating member 62 to move toward the outer tube body 21, thereby pushing the inner rod body 23 out of the frame body 3, thereby realizing the disassembly of the cylinder body 4. This embodiment not only realizes the reception of fibers, but also realizes the disassembly of the cylinder body 4 through a driving device 5, and the manufacturing cost of the device is economical.

[0034] Example 3

[0035] In order to prevent the transmission mechanism from being exposed and the fiber from falling behind the transmission mechanism, thus affecting the operation of the transmission mechanism and limiting the movement of the reciprocating member 62, improvements are made based on Embodiments 1-2, such as Figure 1-2 As shown, in this embodiment, the frame 3 includes: a base 31, the base 31 contains the threaded rod 61; a first side plate 32 and a second side plate 33, the cylinder 4 is mounted between the first side plate 32 and the second side plate 33, the first side plate 32 is rotatably connected to the first rotating shaft 1, the second side plate 33 is connected to the second rotating shaft 2, the first side plate 32 contains the driving gear 7 and the driven gear 8, and the second side plate 33 contains the reciprocating member 62.

[0036] In the specific implementation process, the threaded rod 61 is accommodated in the cavity of the base 31, the gear part is accommodated in the cavity of the first side plate 32, and the reciprocating member 62 is partially accommodated in the cavity of the second side plate 33, so that all transmission mechanisms are not exposed, and in the process of receiving the spun fibers, the fibers will not affect the operation of the transmission mechanisms. At the same time, the width of the cavity in the second side plate 33 can be adapted to the escape distance of the inner rod body 23, and the moving position of the reciprocating member 62 can be limited by the cavity wall of the second side plate 33, eliminating the need for additional limiters, and the structure of the device is simpler.

[0037] Example 4

[0038] In order to completely separate the inner rod body 23 from the frame body 3, improvements are made based on the third embodiment, such as Figure 2-3 As shown, in this embodiment, the reciprocating member 62 includes: a nut 621, which is threadedly connected to the threaded rod 61; a vertical rod 622, the bottom end of which is connected to the nut 621; and a cross rod 623, one end of which is connected to the vertical rod 622, and the other end of which is abutted against the inner rod body 23.

[0039] During the specific implementation process, because the cylinder 4 has a certain height, it is difficult for the nut 621 to directly abut against the inner rod body 23, so a vertical rod 622 is provided. Since one end of the inner rod body 23 is inserted into the cavity of the second side plate 33, and the cavity wall of the second side plate 33 has a certain thickness, directly pushing the inner rod body 23 with the vertical rod 622 cannot make the inner rod body 23 completely detach from the second side plate 33, so a cross rod 623 is provided. The length of the cross rod 623 is greater than the cavity wall of the second side plate 33 close to one end of the inner rod body 23, and the inner rod body 23 can be completely detached from the second side plate 33 through the cross rod 623.

[0040] Example 5

[0041] In order to make the reciprocating member 62 slide better, improvements are made on the basis of embodiment 4, such as Figure 3 As shown, in this embodiment, the reciprocating member 62 further includes: a first slider 624 , the first slider 624 is connected to the side wall of the nut 621 , and the cavity wall of the second side plate 33 is provided with a first sliding groove 331 that cooperates with the first slider 624 .

[0042] In the specific implementation process, when the threaded rod 61 rotates, the nut 621 may be driven to rotate. The utility model can block the vertical rod 622 through the cavity wall, and the vertical rod 622 limits the rotation of the nut 621. However, the friction between the vertical rod 622 and the cavity wall will affect the movement of the nut 621 to a certain extent. Therefore, in this embodiment, Figure 3 As shown, a first slider 624 is provided on the lower side wall of the nut 621, and a first slide groove 331 is provided on the lower cavity wall of the second side plate 33. The slide groove limits the rotation of the nut 621 and utilizes the low friction between the slide groove and the slider to reduce the impact on the movement of the nut 621.

[0043] Example 6

[0044] In order to make the movement of the nut 621 more stable, improvements are made on the basis of Example 5, such as Figure 4 As shown, in this embodiment, the reciprocating member 62 further includes: a second slider 625 , the second slider 625 is connected to the top wall of the vertical rod 622 , and the cavity wall of the second side plate 33 is provided with a second slide groove 332 that cooperates with the second slider 625 .

[0045] In the specific implementation process, the first slider 624 and the second slider 625 can be provided at random or at the same time. Optimally, the reciprocating member 62 is provided with the first slider 624 and the second slider 625 at the same time, so that the forces on the upper and lower sides of the reciprocating member 62 are consistent, and the movement process of the reciprocating member 62 is more stable.

[0046] Example 7

[0047] In order to prevent the inner rod body 23 from rotating, an improvement is made on the basis of Example 6, such as Figure 4-5 As shown, in this embodiment, the inner rod body 23 is plugged into the second side plate 33 , a clamping block 231 is provided on the side wall of the inner rod body 23 , and a clamping groove 333 matched with the clamping block 231 is provided on the second side plate 33 .

[0048] During the specific implementation process, through the cooperation between the block 231 and the slot 333, when the cylinder 4 rotates, the inner rod 23 will not be driven to rotate in the insertion hole of the second side wall, thereby avoiding the friction between the insertion hole and the inner rod 23 hindering the rotation of the cylinder 4.

[0049] Example 8

[0050] In order to simplify the manufacturing process of the device, an improvement is made on the basis of Example 7. In this embodiment, the clamping groove 333 is connected to the second sliding groove 332.

[0051] During the specific implementation process, the shape and size of the locking groove 333 and the second sliding groove 332 are consistent. In essence, the second sliding block 625 and the locking block 231 share a slot body, which has a simple structure and is quick to manufacture.

[0052] Example 9

[0053] In order to simplify the replacement operation of the cylinder 4, as Figure 2 As shown, in this embodiment, the second rotating shaft 2 further includes: a connecting shaft 24 , one end of the connecting shaft 24 is rotatably connected to the outer tube body 21 , and the other end of the connecting shaft 24 is connected to the cylinder body 4 .

[0054] During the specific implementation process, the connecting end structure of the connecting shaft 24 and the cylinder 4 can refer to the first rotating shaft 1, so that the cylinder 4 can be removed without the connecting shaft 24 and the first rotating shaft 1, and at the same time, the connecting shaft 24 is used to rotate with the outer tube body 21, so that the outer tube body 21 and the inner rod body 23 can rotate without rotating with the cylinder 4, reducing rotation obstacles.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
