Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane processing technology, specifically to a winding device for ultrafiltration membrane processing. Background Technology

[0002] Ultrafiltration membranes are microporous filtration membranes with uniform pore size specifications and a rated pore size range of 0.001-0.02 micrometers. In the processing of ultrafiltration membranes, winding is a crucial step, as the quality of winding directly affects the subsequent use and storage of the ultrafiltration membrane. Currently, existing ultrafiltration membrane winding devices often struggle to effectively adjust the winding degree of the ultrafiltration membrane during the winding process. This can lead to problems such as loosening and wrinkling of the ultrafiltration membrane during winding, affecting the quality and winding effect of the ultrafiltration membrane. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0016] Please see Figure 1 As shown, this utility model provides a winding device for ultrafiltration membrane processing, including a frame 1. A positioning vertical plate 4 is installed on the upper left end of the frame 1 by screws. A conveying roller 2 is installed on the inner side of the upper end of the positioning vertical plate 4 by a shaft. A winding roller 3 is rotatably installed inside the right end of the frame 1. A positioning frame 5 is fixedly installed on the outside of the middle end of the frame 1. A drive motor 7 is installed on the upper front of the positioning frame 5. A threaded rod 8 is fixedly installed on the output shaft of the drive motor 7. A pressing block 11 is threadedly connected to the surface of the threaded rod 8. A protrusion is fixedly installed at the bottom of the pressing block 11, and a wedge block 9 is installed below the protrusion. A wedge groove 10 is opened at the top of the wedge block 9. At the same time, the lower end of the protrusion extends to the inner wall of the wedge groove 10 and slides. A pressing roller 13 is installed at the bottom of the wedge block 9 through a connecting seat 12. The pressing roller 13 is located between the conveying roller 2 and the winding roller 3.

[0017] This technical solution, by setting up a drive motor 7, a threaded rod 8, an extrusion block 11, a wedge block 9, and an extrusion roller 13, can easily adjust the tightness of the ultrafiltration membrane during winding, effectively avoiding problems such as loosening and wrinkling during ultrafiltration membrane winding, thus improving winding quality. The cooperation between the guide rod 14 and the sliding block 15 ensures the stability of the movement of the extrusion roller 13, making the tightness adjustment more precise. Example

[0018] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, guide rods 14 are fixedly installed on both the front and rear sides of the inner cavity of the frame 1. Sliding blocks 15 are slidably installed on the outside of the guide rods 14. The inner side of the sliding blocks 15 is rotatably installed with the middle of the extrusion roller 13 via a shaft.

[0019] Adopting such Figure 1 The technical solution shown has guide rods 14 on the front and rear sides of the inner cavity of the frame 1 and sliding blocks 15 cooperating with each other. The inner side of the sliding block 15 is rotatably installed with the middle of the extrusion roller 13 via a shaft. This structure provides precise guidance for the up and down movement of the extrusion roller 13, effectively limiting the deviation of the extrusion roller 13 during the movement process, ensuring that it always moves stably along the preset trajectory. This makes the pressing adjustment of the ultrafiltration membrane by the extrusion roller 13 more stable and precise, avoiding problems such as wrinkles and damage caused by uneven force on the ultrafiltration membrane due to the shaking of the extrusion roller 13, and greatly improving the working stability and winding quality of the winding device.

[0020] Secondly, in the technical solution, a support frame 6 is installed on the upper front of the positioning frame 5 by screws, and the upper end of the support frame 6 is connected to the bottom of the drive motor 7; support pads 16 are fixedly installed on all four sides of the bottom of the frame 1, and the bottom of the support pads 16 is provided with anti-slip texture.

[0021] Its adoption is as follows Figure 1 The technical solution shown has a support frame 6 at the upper front of the positioning frame 5 connected to the bottom of the drive motor 7. This connection method provides stable support for the drive motor 7, disperses the vibration and force generated during its operation, and prevents the drive motor 7 from affecting the running accuracy of components such as the threaded rod 8 due to shaking. At the same time, the screw installation facilitates the maintenance or replacement of the support frame 6 and the drive motor 7 in the future. The support pads 16 around the bottom of the frame 1 not only raise the frame 1 and reduce the corrosion of the frame 1 by ground moisture, but also the anti-slip texture on the bottom can greatly increase the friction with the ground, effectively preventing the device from shifting due to vibration during operation, thus improving the overall stability and reliability of the winding device. Example

[0022] This utility model is as follows Figures 1-3 As shown, support springs are installed on both sides of the bottom of the sliding block 15, and the lower end of the support spring is connected to the bottom of the inner cavity of the frame 1; the upper surface of the extrusion roller 13 is located inside the connecting seat 12, and both ends are fixed by limiting protrusions.

[0023] With the above technical solution, the support springs installed on both sides of the bottom of the sliding block 15 are connected to the bottom of the inner cavity of the frame 1 at their lower ends. They can provide elastic support for the sliding block 15 and the extrusion roller 13 connected to it. When the extrusion roller 13 moves up and down to adjust the pressure, it can buffer the instantaneous impact force and avoid hard contact causing damage to the components. At the same time, it helps the extrusion roller 13 to quickly reset after adjustment, ensuring the stability of the adjustment process. The upper surface of the extrusion roller 13 is located inside the connecting seat 12 and is fixed at both ends by limiting protrusions. This double limiting structure can firmly lock the extrusion roller 13 and prevent it from axial movement or falling off when it applies pressure to the ultrafiltration membrane or moves with the membrane. This ensures that the extrusion roller 13 always acts stably on the ultrafiltration membrane, further improving the safety of the device operation and the consistency of the winding effect.

[0024] The working principle of this utility model is as follows: When it is necessary to adjust the winding tightness of the ultrafiltration membrane, the drive motor 7 is started, and the drive motor 7 drives the threaded rod 8 to rotate. Since the extrusion block 11 is threadedly connected to the threaded rod 8, the rotation of the threaded rod 8 will cause the extrusion block 11 to move left and right on the threaded rod 8. The protrusion at the bottom of the extrusion block 11 slides in the wedge groove 10 at the top of the wedge block 9. As the extrusion block 11 moves, it will push the wedge block 9 to move up and down. The wedge block 9 drives the extrusion roller 13 to move up and down through the connecting seat 12, thereby changing the pressure of the extrusion roller 13 on the ultrafiltration membrane and realizing the adjustment of the winding tightness. During the up and down movement of the extrusion roller 13, the sliding block 15 will slide along the guide vertical rod 14. The support spring will play a buffering and supporting role on the sliding block 15. When the extrusion roller 13 is reset, the support springs at both ends will squeeze the sliding block 15 and quickly reset the extrusion roller 13 and keep it stable.
