Description

Technical Field

[0001] This utility model belongs to the field of nickel wire braided mesh production technology, and specifically relates to a nickel wire braided mesh tension adaptive adjustment device. Background Technology

[0002] Nickel wire braided mesh is a metal mesh structure made of high-purity nickel wire woven together by warp and weft. It is widely used in the energy, chemical, electronics, environmental protection and aerospace industries. For example, nickel wire braided mesh can be used as the anode and cathode material for hydrogen production by water electrolysis, and can be used to make circuit board shielding layers and battery plates.

[0003] After the nickel wire mesh is processed, it needs to be wound up, which requires the use of automatic winding equipment. However, most automatic winding equipment is difficult to adjust the tension of the nickel wire mesh according to the winding requirements.

[0004] A search revealed that Chinese utility model patent CN222860748U discloses a "film winding tension adjustment mechanism", which includes a main body mechanism and an adjustment mechanism. The main body mechanism includes a base, a left plate and a right plate slidably connected to the base, and a limiting rod installed in the gap between the top of the left plate and the right plate to limit the opening distance between the left plate and the right plate. One end of the limiting rod is fixedly installed on the left plate, and the other end of the limiting rod is inserted into the right plate. The rod part of the limiting rod that passes through the right plate is threadedly connected to a limiting nut.

[0005] While existing winding tension adjustment mechanisms, including those mentioned above, can adjust the winding tension, they lack sufficient safety. This is mainly because the horizontal angle of the feed guide roller is not adjustable, which can easily lead to material stretching, wrinkling, or breakage due to uneven tension. For example, during the winding process, uneven tension between the edge and center of the feed guide roller can increase the risk of loosening at the edge or bulging at the center of the nickel wire braided mesh.

[0006] To address the aforementioned issues, this application proposes a nickel wire braided mesh tension adaptive adjustment device. Utility Model Content

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0045] Please see Figures 1-4 The present invention provides the following technical solution: a nickel wire braided mesh tension adaptive adjustment device, including a base 1, and further including: a feeding guide component 2, two sets of liftable support components 3 that are movably installed on the base 1, a transition roller 4 that is rotatably installed between the two sets of liftable support components 3, and a power component 5 for driving the liftable support components 3 to rise and fall.

[0046] Furthermore, by Figure 1 and Figure 4 As shown, in this embodiment, the feeding guide assembly 2 includes a turntable 21 rotatably mounted on the base 1, two first-side support plates 22 symmetrically fixed to the turntable 21, a feeding guide roller 23 rotatably mounted between the two first-side support plates 22, a first-side stud 25 fixed to the base 1, and a first-side wing nut 26 threadedly engaged with the first-side stud 25. The first-side stud 25 passes through an arc-shaped sliding hole 211 opened on the turntable 21. With the above solution, during use, the first-side wing nut 26 is first loosened according to the feeding angle requirement of the nickel wire braided mesh. Nut 26, because the first stud 25 passes through the arc-shaped sliding hole 211 on the turntable 21, the turntable 21 can rotate around its rotation connection point with the base 1, thereby driving the two first side support plates 22 and the feed guide roller 23 to rotate. Adjust the angle of the feed guide roller 23 to a suitable position to guide the nickel wire braided mesh into the subsequent processing area at the appropriate angle. After the adjustment is completed, tighten the first wing nut 26. The turntable 21 is fixed by the threaded engagement of the first stud 25 and the first wing nut 26, so that the feed guide roller 23 is kept at the required angle.

[0047] When the tension of the nickel wire braided mesh needs to be adjusted, the power unit 5 is activated, driving the two sets of liftable support components 3 to rise and fall synchronously.

[0048] The lifting and lowering of the adjustable support assembly 3 drives the transition roller 4 to move in the vertical direction. Since the transition roller 4 is rotatably installed between the two sets of adjustable support assemblies 3, and the nickel wire braided mesh will pass around the transition roller 4, when the transition roller 4 rises, it will apply an upward pulling force to the nickel wire braided mesh (the specific force depends on the introduction position of the nickel wire braided mesh; here, we will take the example of the nickel wire braided mesh passing over the transition roller 4 from above) to increase the tension of the braided mesh. When the transition roller 4 falls, the pulling force on the braided mesh decreases, and the tension decreases accordingly.

[0049] By precisely controlling the lifting height of the adjustable support component 3 through the power component 5, the position of the transition roller 4 can be adjusted, thereby adaptively adjusting the tension of the nickel wire braided mesh to meet different production process requirements.

[0050] Throughout the adjustment process, the feed guide component 2 ensures that the nickel wire braided mesh is input at a stable angle, and the transition roller 4 adjusts the tension in real time through position changes. The components work together to enable the device to flexibly and accurately adjust the tension of the nickel wire braided mesh according to actual needs.

[0051] Optionally, by Figure 1 and Figure 4 As shown in this embodiment, the feeding guide component 2 further includes a fixing column 24 fixed to the base 1. The fixing column 24 passes through the center of the turntable 21 to form a rotating structure. With the above solution, when in use, the fixing column 24 serves as the central rotation fulcrum of the turntable 21, passes through the center of the turntable 21 and is fixedly connected to the base 1 to form a stable rotating support structure.

[0052] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, there are two symmetrically distributed arc-shaped sliding holes 211, stud 25, and wing nut 26. With the above scheme, the symmetrical design forms a bidirectional constraint on the turntable 21 during use, so that the radial force borne by the turntable 21 in the fixed state is evenly distributed on both sides.

[0053] When the nickel wire braided mesh generates lateral tension on the feed guide roller 23, the symmetrical structure can effectively counteract the eccentric torque, prevent the turntable 21 from tilting or rotating eccentrically due to unilateral force, ensure that the axis of the feed guide roller 23 always remains horizontal or at the target angle, and improve the stability of the feeding process.

[0054] Compared to a single-sided fixed structure, the symmetrical layout distributes the single-point load into two-point support, significantly reducing the local stress at the connection between the turntable 21 and the fixed column 24.

[0055] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the liftable support assembly 3 includes: a U-shaped support 31, a movable block 32 located inside the U-shaped support 31, a top plate 33 detachably installed at the top of the U-shaped support 31, and a pressure sensor 34 fixed to the bottom surface of the top plate 33. The transition roller 4 is rotatably installed between the two movable blocks 32, and the top surface of the movable block 32 is in contact with the bottom surface of the pressure sensor 34. With the above solution, when in use, the power assembly 5 outputs power to drive the U-shaped support 31 to move vertically up and down, thereby driving the movable block 32, the top plate 33 and the transition roller 4 to move synchronously.

[0056] The top surface of the moving block 32 is in close contact with the bottom surface of the pressure sensor 34, forming a force transmission path: when the tension of the woven mesh changes, the transition roller 4 generates vertical pressure on the moving block 32 (the pressure increases when the tension increases and decreases when the tension decreases), and this pressure is collected in real time by the pressure sensor 34 and converted into an electrical signal.

[0057] The pressure sensor 34 is fixed to the bottom surface of the top plate 33, while the top plate 33 is detachable and installed on the top of the U-shaped support 31, which ensures the rigidity of force transmission and facilitates the calibration or replacement of the pressure sensor 34 in the future.

[0058] The pressure sensor 34 is connected to the control center of the adjustment device (not shown in the figure). If the detected pressure value is less than the reference value corresponding to the target tension, it indicates that the tension of the woven mesh is insufficient. The control system drives the power component 5 to lift the U-shaped support 31, which drives the transition roller 4 to rise, increasing the tension of the woven mesh until the feedback value of the pressure sensor 34 reaches the set range. Conversely, it drives the transition roller 4 to fall, reducing the tension of the woven mesh.

[0059] Optionally, by Figure 1 and Figure 2 As shown in this embodiment, the liftable support assembly 3 further includes: a second stud 35 symmetrically fixed to the top of the U-shaped support 31 and a second wing nut 36 threadedly engaged with the protruding end of the second stud 35. The second stud 35 penetrates the top plate 33. With the above solution, the top plate 33 is fixedly installed by the cooperation of the second stud 35 and the second wing nut 36 during use, which not only ensures the rigidity of force transmission, but also facilitates the calibration or replacement of the pressure sensor 34 in the later stage.

[0060] When installing the top plate 33, first let the second stud 35 pass through the top plate 33, and then tighten the second wing nut 36 at the protruding end of the second stud 35 to lock it. When it is necessary to remove the top plate 33, simply unscrew the second wing nut 36 to remove the top plate 33.

[0061] Optionally, by Figure 1 and Figure 3As shown, in this embodiment, the power assembly 5 includes: two symmetrically distributed movable seats 51, a flip support rod 52 hinged between the movable seats 51 and the U-shaped support 31, two fixed plates 53 symmetrically fixed to the base 1, a bidirectional threaded screw 54 rotatably mounted between the two fixed plates 53, and a servo motor 55 for driving the bidirectional threaded screw 54 to rotate. The movable seats 51 and the bidirectional threaded screw 54 are threadedly engaged, and the servo motor 55 is fixed to the fixed plate 53. With the above scheme, when in use, the servo motor 55 outputs rotational power after being powered on, and its output shaft drives the bidirectional threaded screw 54 to rotate around its axis using a coupling. Since the two ends of the bidirectional threaded screw 54 are respectively machined with left-hand and right-hand threads, the two movable seats 51 that are threadedly engaged with it will make opposite or opposite linear movements when the bidirectional threaded screw 54 rotates: when the bidirectional threaded screw 54 rotates clockwise, the two movable seats 51 move towards the middle; when it rotates counterclockwise, the two movable seats 51 move apart to the sides.

[0062] When the two movable seats 51 move closer to the middle, the angle between the flipping support rod 52 and the horizontal plane increases, pushing the U-shaped support 31 to rise, which in turn drives the transition roller 4 to rise synchronously, increasing the tension of the nickel wire braided mesh.

[0063] When the movable seat 51 separates to both sides, the angle between the flipping support rod 52 and the horizontal plane decreases, the U-shaped support 31 descends, and the transition roller 4 lowers, causing the woven mesh to loosen and the tension to decrease.

[0064] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the power assembly 5 further includes a guide rod 56 fixed between two fixed plates 53, and the guide rod 56 passes through the movable seat 51. With the above solution, during use, the guide rod 56 is used to limit the moving direction of the movable seat 51, so that the movable seat 51 can only move along the axial direction of the guide rod 56, thereby further improving the stability of the movable seat 51.

[0065] Preferably, by Figure 1 As shown, this embodiment also includes a discharge guide component 6, which includes two second-side support plates 61 symmetrically fixed to the base 1 and a discharge guide roller 62 rotatably installed between the two second-side support plates 61. With the above scheme, when in use, the nickel wire braided mesh is guided to the subsequent process by the discharge guide roller 62 after the tension is adjusted by the transition roller 4.

[0066] In addition, the discharge guide roller 62 and the feed guide roller 23 cooperate to support the two ends of the nickel wire braided mesh respectively, and the transition roller 4 is located on the inner side to achieve a stable tension adjustment function.

[0067] It should be noted that the pressure sensor 34 and the servo motor 55 are both commercially available standard devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0068] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0069] Components not described in detail in this article are existing technologies.

[0070] The working principle and usage process of this utility model: When using the nickel wire braided mesh tension adaptive adjustment device of this utility model, firstly, according to the required feeding angle of the nickel wire braided mesh, loosen the first wing nut 26. Since the first stud 25 passes through the arc-shaped sliding hole 211 on the turntable 21, the turntable 21 can rotate around its rotation connection point with the base 1, thereby driving the two first side support plates 22 and the feeding guide roller 23 to rotate. Adjust the angle of the feeding guide roller 23 to a suitable position to guide the nickel wire braided mesh into the subsequent processing area at an appropriate angle. After the adjustment is completed, tighten the first wing nut 26. The turntable 21 is fixed by the threaded engagement of the first stud 25 and the first wing nut 26, so that the feeding guide roller 23 is kept at the required angle.

[0071] When it is necessary to adjust the tension of the nickel wire braided mesh, the power component 5 is activated, driving the two sets of liftable support components 3 to rise and fall synchronously.

[0072] The lifting and lowering of the adjustable support assembly 3 drives the transition roller 4 to move in the vertical direction. Since the transition roller 4 is rotatably installed between the two sets of adjustable support assemblies 3, and the nickel wire braided mesh will pass around the transition roller 4, when the transition roller 4 rises, it will apply an upward pulling force to the nickel wire braided mesh, increasing the tension of the braided mesh.

[0073] When the transition roller 4 is driven to descend by the power component 5, the tension on the woven mesh decreases, and the tension decreases accordingly.

[0074] By precisely controlling the lifting height of the liftable support component 3 through the power component 5, the position of the transition roller 4 can be adjusted, thereby adaptively adjusting the tension of the nickel wire braided mesh to meet different production process requirements.

[0075] Throughout the adjustment process, the feed guide component 2 ensures that the nickel wire braided mesh is input at a stable angle, and the transition roller 4 adjusts the tension in real time through position changes. The components work together to enable the device to flexibly and accurately adjust the tension of the nickel wire braided mesh according to actual needs.

[0076] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
