Description

Technical Field

[0001] This utility model belongs to the technical field of adjustment devices, and specifically relates to a floating frame tension roller adjustment device. Background Technology

[0002] Electrolytically formed foil, a key material processed through special techniques, is made from specially treated high-purity aluminum foil. The surface area is expanded through electrochemical or chemical etching, and then an aluminum oxide film is formed on the surface via electrochemical forming. Based on voltage, it can be classified into four types: ultra-low voltage, low voltage, medium-high voltage, and high voltage. In the production and processing of electrolytically formed foil, the tension roller adjustment device plays a crucial role, and its performance directly affects the product quality.

[0003] The existing floating frame tension roller adjustment device has many problems in practical application. The operation process of adjusting the tension roller is cumbersome and not convenient and efficient, which greatly affects the production efficiency. At the same time, it cannot effectively prevent wrinkles from forming the foil during the process of guiding the foil, which seriously affects the quality of the finished foil.

[0004] To address the aforementioned issues, a floating frame tension roller adjustment device has been introduced in the relevant technical field. Among them, Chinese Patent No. CN216403293U discloses a floating frame tension roller adjustment device. This device includes a first roller, which is fixedly sleeved on a first connecting shaft. The left and right ends of the first connecting shaft extend into a first T-groove and are movably connected to a first bearing. A connecting rod is fixedly connected to the upper end of the first bearing, and a first spring is sleeved on the connecting rod. A third roller is provided between two sets of second support plates. The left and right ends of the third connecting shaft are movably connected to the two sets of second support plates through the third bearing. The operation method is to pull the lever upward to lift the first roller, pass the formed foil through the lower end of the third roller, and clamp it between the first roller and the second roller. The connecting block returns to its original position, realizing automatic adjustment of the roller tension. The operation is convenient. At the same time, during the winding process, the formed foil is always clamped between the first roller and the second roller to prevent the formed foil from shifting and wrinkling.

[0005] However, while the aforementioned device offers advantages such as ease of operation and the ability to prevent wrinkles in the formed foil to a certain extent, its overall structure is relatively simple and has significant drawbacks in practical use. On the one hand, it cannot quickly and automatically adjust the tension, making it difficult to adapt to the precise tension requirements of the formed foil under different production conditions. On the other hand, the outer surfaces of each guide roller and conveyor roller lack limiting structures. When the required foil width is different, the foil roll is prone to lateral displacement on each guide roller and conveyor roller, resulting in unstable conveying and affecting the production quality and efficiency of the formed foil. Therefore, it is necessary to improve the design of the existing floating frame tension roller adjustment device to overcome the above shortcomings. Utility Model Content

[0006] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a floating frame tension roller adjustment device to solve the problems raised in the background art.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A floating frame tension roller adjusting device includes a base plate, an upright plate fixedly installed on the top rear side of the base plate, a tension adjusting mechanism fixedly installed in the middle of the upright plate, guide rollers fixedly installed on both sides of the upper front of the upright plate, and a limiting mechanism fixedly installed in the middle of the top of the base plate, with the limiting end of the limiting mechanism sleeved on the outer surface of the guide rollers and the tension adjusting mechanism.

[0009] The tension adjustment mechanism includes a vertical rail, which is fixedly installed in the middle of the vertical plate. A first motor is fixedly installed at the bottom of the vertical rail. The output end of the first motor passes through the vertical rail and is fixedly installed with a first lead screw. The first lead screw is rotatably connected to the inside of the vertical rail, and a tension adjustment group is threadedly connected to the outer surface of the first lead screw.

[0010] As a preferred technical solution, the tension adjustment component includes a slider, which is slidably connected to the inside of the vertical rail and threadedly connected to the outer surface of the first lead screw. A top plate is fixedly installed on the front of the slider, and telescopic springs are fixedly connected to the bottom of the top plate in a linear arrangement at equal intervals. A base plate is fixedly installed on the bottom of the telescopic springs, and a pressure sensor is fixedly installed in the middle of the bottom of the base plate. A concave frame is fixedly installed on the bottom of the pressure sensor, and a pressure roller is rotatably connected inside the concave frame.

[0011] As a preferred technical solution, support rods are fixedly installed at both ends of the top of the substrate, the upper ends of the support rods penetrate the top plate, and the top plate and the support rods are slidably connected to each other.

[0012] As a preferred technical solution, side mounting plates are fixedly installed at both ends of the base plate, and mounting holes are provided at both ends of the side mounting plates, which are countersunk holes.

[0013] As a preferred technical solution, the limiting mechanism includes a guide rail, which is fixedly installed in the middle of the top of the base plate. A second lead screw is rotatably connected inside the guide rail. The two ends of the second lead screw have opposite thread directions. Both ends of the second lead screw are threadedly connected to movable blocks. A limiting card group is fixedly installed on the outside of the movable blocks. The limiting end of the limiting card group is sleeved on the outer surface of the guide roller and the pressure roller. A second motor is fixedly installed at the front end of the guide rail.

[0014] As a preferred technical solution, the limiting card group includes side arms, which are fixedly installed on both sides of the movable block. Side limiting rings are fixedly installed on the outer ends of the side arms, and the side limiting rings are slidably connected to both ends of the outer surface of the guide roller.

[0015] As a preferred technical solution, the limiting card group further includes a hexagonal sleeve, which is fixedly installed on the top of the movable block. A hexagonal support rod is slidably connected inside the hexagonal sleeve, and a middle limiting ring is fixedly installed on the top of the hexagonal support rod. The middle limiting ring is sleeved on both ends of the outer surface of the pressure roller.

[0016] In summary, the present invention has the following main advantages:

[0017] Firstly, by setting up a closed-loop tension adjustment system consisting of a first motor, a first lead screw, a pressure roller, a pressure sensor, and a telescopic spring, the first motor can drive the first lead screw to flexibly raise and lower the pressure roller during use. The pressure sensor can detect the pressure value of the pressure roller on the electroforming foil in real time and transmit the signal to the control system. The control system adjusts the operation of the first motor according to the signal to adjust the position of the pressure roller. At the same time, the telescopic spring deforms with the pressure change to buffer pressure fluctuations. This process achieves rapid response and automatic adjustment of the electroforming foil tension, ensuring that the tension on the electroforming foil is stable within the set range. This achieves the effect of accurately adapting to the tension requirements of the electroforming foil under different production conditions, solving the problem that the existing device in the background technology has a simple overall structure, cannot quickly and automatically adjust the tension, and is difficult to adapt to different production needs.

[0018] Secondly, by setting up a limiting mechanism consisting of a second motor, a second lead screw, movable blocks, and a limiting card group, during use, when the second motor drives the second lead screw to rotate, the two sets of movable blocks will drive the limiting card group to move synchronously in opposite directions or away from each other. The side limiting ring slides along the guide roller, and the middle limiting ring slides in the hexagonal sleeve through a hexagonal support rod to adaptively adjust its height as the pressure roller rises and falls. Ultimately, the side limiting ring and the middle limiting ring are tightly fitted to the two sides of the forming foil of different widths. This design achieves reliable lateral limiting of the forming foil, effectively preventing it from shifting laterally during transmission, thereby ensuring stable transmission of the forming foil. This solves the problem in the prior art where the existing device lacks a limiting structure on the outer surface of the guide roller and transmission roller, leading to easy lateral shifting and unstable transmission of the foil roll.

[0025] Example

[0026] refer to Figures 1 to 5 The floating frame tension roller adjustment device of this embodiment includes a base plate 1, a vertical plate 2 fixedly installed on the top rear side of the base plate 1, a tension adjustment mechanism 3 fixedly installed in the middle of the vertical plate 2, guide rollers 4 fixedly installed on both sides of the upper front of the vertical plate 2, and a limiting mechanism 5 fixedly installed in the middle of the top of the base plate 1. The limiting end of the limiting mechanism 5 is sleeved on the outer surface of the guide rollers 4 and the tension adjustment mechanism 3.

[0027] The tension adjustment mechanism 3 includes a vertical rail 31, which is fixedly installed in the middle of the vertical plate 2. A first motor 32 is fixedly installed at the bottom of the vertical rail 31. The output end of the first motor 32 passes through the vertical rail 31 and is fixedly installed with a first lead screw 33. The first lead screw 33 is rotatably connected to the inside of the vertical rail 31. A tension adjustment assembly 34 is threaded onto the outer surface of the first lead screw 33. When this floating frame tension roller adjustment device is working, the electrolytic foil is first passed between the guide roller 4 and the tension adjustment mechanism 3. The base plate 1 provides stable support for the entire device, while the vertical plate 2 is fixedly installed with the tension adjustment mechanism 3 and the guide roller 4 to ensure that the positions of each component are stable. The tension adjustment mechanism 3 is then started. The first motor 32 of the force adjustment mechanism 3 drives the first lead screw 33, which passes through the vertical rail 31, to rotate inside the vertical rail 31. Since the components of the tension adjustment group 34 are threadedly connected to the outer surface of the first lead screw 33 and are limited by the vertical rail 31, the tension adjustment group 34 will move up and down along the vertical rail 31 when the first lead screw 33 rotates. In turn, the tension is adjusted by contact with the chemically formed foil. The guide roller 4 plays a supporting and guiding role for the chemically formed foil, ensuring that the chemically formed foil maintains a stable path during the conveying process. The limiting end of the limiting mechanism 5 is sleeved on the outer surface of the guide roller 4 and the tension adjustment mechanism 3, which can prevent the chemically formed foil from shifting to the side, so that the entire device works together to complete the tension adjustment of the chemically formed foil.

[0028] refer to Figures 1-4The limiting mechanism 5 includes a guide rail 51, which is fixedly installed in the middle of the top of the base plate 1. A second lead screw 52 is rotatably connected inside the guide rail 51. The two ends of the second lead screw 52 have opposite thread directions. Both ends of the second lead screw 52 are threadedly connected to movable blocks 53. A limiting assembly 55 is fixedly installed on the outside of the movable blocks 53. The limiting end of the limiting assembly 55 is sleeved on the outer surface of the guide roller 4 and the pressure roller 347. A second motor 54 is fixedly installed at the front end of the guide rail 51. The limiting assembly 55 includes side arms 551, which are fixedly installed on both sides of the movable blocks 53. A side limiting ring 552 is fixedly installed on the outer end of the side arm 551. The side limiting ring 552 is slidably connected to both ends of the outer surface of the guide roller 4. The limiting block 55 also includes a hexagonal sleeve 553, which is fixedly installed on the top of the movable block 53. A hexagonal support rod 554 is slidably connected inside the hexagonal sleeve 553. A middle limiting ring 555 is fixedly installed on the top of the hexagonal support rod 554. The middle limiting ring 555 is sleeved on both ends of the outer surface of the pressure roller 347. During the application of this device, when the limiting mechanism 5 is working, the guide rail 51 is fixed to the middle of the top of the base plate 1. To provide stable support for the entire mechanism, the second motor 54 is fixed to the front end of the guide rail 51. Its output end drives the second lead screw 52 inside the guide rail 51 to rotate. Since the threads at both ends of the second lead screw 52 turn in opposite directions and are respectively threaded to movable blocks 53, when the second lead screw 52 rotates, the two sets of movable blocks 53 will move synchronously towards or away from each other along the guide rail 51. The limiting clamps 55 on the outside of the movable blocks 53 move accordingly. The side arm 551 drives the side limiting ring 552 at the outer end to slide along both ends of the outer surface of the guide roller 4, thereby laterally limiting the chemically formed foil on the guide roller 4. At the same time... The hexagonal support rod 554, which is slidably connected inside the hexagonal sleeve 553 at the top of the movable block 53, drives the middle limiting ring 555 at the top to move synchronously. The middle limiting ring 555 is sleeved on both ends of the outer surface of the pressure roller 347, and can achieve height self-adjustment by sliding the hexagonal support rod 554 inside the hexagonal sleeve 553 as the pressure roller 347 rises and falls, ensuring that the chemically formed foil on the pressure roller 347 is always effectively limited. Through such coordinated operation, the limiting mechanism 5 can flexibly adjust the limiting position according to the width of the chemically formed foil to prevent the chemically formed foil from shifting laterally on the guide roller 4 and the pressure roller 347.

[0029] refer to Figures 1-3Side mounting plates 6 are fixedly installed at both ends of the base plate 1. Mounting holes 7 are provided at both ends of the side mounting plates 6, and these holes are countersunk. During the application of this device, the side mounting plates 6 at both ends of the base plate 1 mainly serve to fix the entire device. The mounting holes 7 at both ends provide connection points for the installation of the device. During installation, the side mounting plates 6 are connected to the external fixed structure through the mounting holes 7. Using bolts or other connecting parts passing through the mounting holes 7, the base plate 1 and the entire device can be securely installed in the required position. The countersunk design of the mounting holes 7 allows the bolt heads to be completely recessed into the holes, preventing the bolt heads from protruding from the surface of the side mounting plates 6. This ensures that the bolt heads will not collide or interfere with other components during device operation, guaranteeing the smooth operation of all components. It also enhances the overall aesthetics and structural compactness of the installed device, providing a fundamental guarantee for its stable operation.

[0030] refer to Figures 1-3 and Figure 5 The tension adjustment assembly 34 includes a slider 341, which is slidably connected to the inside of the vertical rail 31 and threadedly connected to the outer surface of the first lead screw 33. A top plate 342 is fixedly installed on the front of the slider 341. Telescopic springs 343 are linearly arranged and fixedly connected at equal intervals at the bottom of the top plate 342. A base plate 344 is fixedly installed at the bottom of the telescopic springs 343. A pressure sensor 345 is fixedly installed in the middle of the bottom of the base plate 344. A concave frame 346 is fixedly installed at the bottom of the pressure sensor 345. A pressure roller 347 is rotatably connected inside the concave frame 346. Support rods 348 are fixedly installed at both ends of the top of the base plate 344. The upper ends of the support rods 348 penetrate the top plate 342. The top plate 342 and the support rods 348 are slidably connected to each other. During the application of this device, when the tension adjustment assembly 34 is working, the slider 341 slides due to its threaded connection with the first lead screw 33. Connected inside the vertical rail 31, when the first lead screw 33 rotates under the drive of the first motor 32, the slider 341 will slide stably along the vertical rail 31, thereby driving the top plate 342 fixed on the front to move synchronously. The telescopic springs 343 arranged at equal intervals at the bottom of the top plate 342 are connected to the substrate 344. The upper ends of the support rods 348 at both ends of the top of the substrate 344 pass through the top plate 342 and are slidably connected to the top plate 342, which can limit the movement direction of the substrate 344 and the top plate 342 to avoid deviation. The pressure sensor 345 at the bottom of the substrate 344 can detect in real time the pressure of the pressure roller 347 rotatably connected in the concave frame 346 below on the forming foil. When the tension of the forming foil changes, causing the pressure to change, the pressure sensor 345 will feed back the signal. By adjusting the position of the slider 341, the top plate 342 will move, causing the telescopic springs 343 to extend and retract, thereby changing the pressure of the pressure roller 347 on the forming foil and realizing tension adjustment.

[0031] Operating principle and advantages: During the application of this device, the device is first installed and fixed. Using the mounting holes 7 on the mounting plates 6 at both ends of the base plate 1, the entire device is firmly fixed to the designated position on the electrolytic foil production line using appropriate bolts. During this process, it is necessary to ensure that the bolts are fully embedded in the countersunk holes and tightened to prevent loosening due to vibration during long-term operation and to ensure the overall stability of the device during operation. After installation, the electrolytic foil is threaded through. Both ends of the electrolytic foil are passed over the top of the guide rollers 4 on both sides, allowing the middle part to hang naturally and be below the pressure roller 347. This places the electrolytic foil within the support range of the guide rollers 4 and the pressing range of the pressure roller 347, completing the initial positioning of the electrolytic foil within the device and laying the foundation for subsequent tension adjustment and conveying operations.

[0032] Then, the tension adjustment process is initiated. The first motor 32 is started, and its output end drives the first lead screw 33 to rotate along its own axis inside the vertical rail 31 via a coupling. Since the inner side of the slider 341 is slidably connected to the inner wall of the vertical rail 31 and its inner thread is adapted to the outer thread of the first lead screw 33, the slider 341 moves up and down along the length of the vertical rail 31 when the first lead screw 33 rotates. This, in turn, drives the telescopic spring 343, the bottom plate 1, the pressure sensor 345, the concave frame 346, and the pressure roller 347 to move up and down synchronously through the top plate 342 until the outer surface of the pressure roller 347 contacts the upper surface of the formed foil and applies a preset initial pressure. At this time, the pressure roller 347 moves downward under the driving force, while the guide roller 4 remains stationary. The pressure difference between the two can generate a continuous force on the formed foil, achieving a good tensioning effect. During the continuous conveying of the formed foil, the device enters the real-time tension adjustment stage. The pressure sensor 345 continuously detects the pressure value exerted on the formed foil by the pressure roller 347 and transmits the detected pressure signal to the control system in real time. When the tension of the formed foil fluctuates due to factors such as changes in conveying speed or uneven material thickness, the signal fed back by the pressure sensor 345 will change accordingly. After receiving the signal, the control system will adjust the rotation direction and speed of the first motor 32 according to the preset tension range, causing the first lead screw 33 to drive the slider 341 to move up and down accordingly, thereby adjusting the pressure of the pressure roller 347 on the formed foil. At the same time, the telescopic spring 343 will deform accordingly according to the pressure change, using its own elastic potential energy to help buffer the pressure fluctuations and ensure that the tension on the formed foil is stable within the set range. Among them, the upper ends of the support rods 348 at both ends of the top of the base plate 1 penetrate through the top plate 342 and maintain a sliding connection with the top plate 342, which can strictly limit the direction of the top plate 342 and the base plate 1 during the up and down movement, preventing them from shifting laterally due to uneven force and ensuring the accuracy of tension adjustment.

[0033] During the simultaneous tension adjustment process, the limiting mechanism 5 needs to be adjusted. Based on the required width of the formed foil for current production, the second motor 54 is started. The output of the second motor 54 drives the second lead screw 52 to rotate inside the guide rail 51. Since the threads at both ends of the second lead screw 52 rotate in opposite directions, and the movable blocks 53 at both ends are respectively matched with the threads at corresponding positions, when the second lead screw 52 rotates, the two sets of movable blocks 53 will move synchronously towards or away from each other along the guide rail 51, thereby driving the two sets of limiting clamps 55 to move synchronously. During this process, the side arm 551 will drive the side limiting ring 552 to slide smoothly along the outer surface of the guide roller 4, while the middle limiting ring 555 will achieve adaptive height adjustment through the sliding of the hexagonal support rod 554 within the hexagonal sleeve 553, to coordinate with the lifting and lowering movement of the pressure roller 347, until the inner sides of the side limiting ring 552 and the middle limiting ring 555 are tightly fitted with the two side edges of the formed foil, completing the lateral limiting of the formed foil. This design allows for flexible adjustment of the positions of the side limiting ring 552 and the middle limiting ring 555, thereby enabling precise positioning of chemically formed foil rolls of different widths. This ensures that the chemically formed foil remains on the preset path during the conveying process, giving it good operational stability. At the same time, the adjustable structural design further improves the overall adaptability of the device under different production conditions.

[0034] During the application of this device, its various structural components have clear division of labor and work together. The base plate 1 and the upright plate 2 together form the main frame of the device. The base plate 1 provides a stable support foundation for the entire device, while the upright plate 2 provides a reliable mounting carrier for the tension adjustment mechanism 3 and the guide roller 4. In the tension adjustment mechanism 3, the vertical rail 31 provides a guide track for the up and down movement of the slider 341, ensuring the linearity of the slider 341's movement. The first motor 32 serves as a power source to drive the first lead screw 33 to rotate, converting the rotational motion into linear motion through the slider 341, thereby realizing the lifting and lowering of subsequent components. The telescopic spring 343 can generate elastic deformation when the pressure changes, playing the role of buffering pressure and absorbing vibration. The pressure sensor 345 serves as a detection element to monitor the pressure data in real time and feed it back to the control system. The concave frame 346 provides an installation position for the pressure roller 347 and ensures its rotational flexibility. The pressure roller 347 is in direct contact with the formed foil and adjusts the tension on the formed foil by changing its own position. The guide roller 4 supports and guides the formed foil, ensuring that the formed foil maintains a stable path during the conveying process and avoiding irregular deviations. In the limiting mechanism 5, the guide rail 51 provides a stable track for the movement of the movable block 53. The second lead screw 52 realizes the synchronous reverse movement of the two sets of movable blocks 53 through reverse thread transmission. The movable block 53 drives the limiting card group 55 to realize position adjustment. The side limiting ring 552 and the middle limiting ring 555 directly act on the two sides of the formed foil, playing a lateral limiting role. The second motor 54 provides power for the limiting adjustment. The cooperation between the hexagonal sleeve 553 and the hexagonal support rod 554 ensures that the middle limiting ring 555 can rise and fall synchronously with the pressure roller 347, always maintaining a good contact state with the formed foil. The side mounting plate 6 and the mounting hole 7 are used to fix the device on the production line. The countersunk hole design avoids the bolt head protruding and interfering with the movement of other parts.

[0035] As can be seen, this device uses the first motor 32 to drive the first lead screw 33 to raise and lower the pressure roller 347. Combined with the real-time feedback from the pressure sensor 345 and the buffering effect of the telescopic spring 343, a closed-loop tension adjustment system is formed, which can realize rapid and automatic adjustment of the tension of the electroforming foil. This effectively solves the problem that the device in the background technology cannot quickly and automatically adjust the tension, and can adapt to the precise requirements of electroforming foil tension under different production conditions. In the limiting mechanism 5, the second motor 54 drives the second lead screw 52 to move the limiting clamp group 55 synchronously, thereby limiting the movement of the limit. Positioning ring 552 and middle limiting ring 555 can reliably limit the width of the formed foil, preventing it from shifting laterally during the conveying process. This solves the problem of unstable conveying of formed foil caused by the lack of limiting structure in the prior art. Support rod 348 restricts the movement direction of top plate 342 and bottom plate 1. Side mounting plate 6 and mounting hole 7 ensure that the whole device is firmly fixed, avoiding structural displacement caused by vibration during operation. This ensures the stability of formed foil conveying and tension adjustment from multiple aspects, and improves the quality and efficiency of formed foil production and processing.

[0036] During the application of this device, the guide rail 51 has a length of 300-500mm and a cross-sectional dimension of 50mm×50mm; the second lead screw 52 has a diameter of 15-25mm, a length adapted to the guide rail 51, and a thread pitch of 2-4mm at both ends; the movable block 53 has a length of 80-120mm and a width of 50-70mm; the side arm 551 has a length of 100-150mm, the inner diameter of the side limiting ring 552 is 0.5-1mm larger than the outer diameter of the guide roller 4, and the inner diameter of the middle limiting ring 555 is 0.5-1mm larger than the outer diameter of the pressure roller 347; the hexagonal sleeve 553 has a length of 80-120mm and a hexagonal support... The diameter of rod 348 is adapted to the inner cavity of hexagonal sleeve 553, and its length is 50-80mm longer than that of hexagonal sleeve 553. The second motor 54 is a stepper motor of model 57BYG250H with a rated voltage of 24V and a rated current of 3A. The controller is a single-chip microcomputer of model STM32F103C8T6, which is installed in the middle of the back of the upright plate 2. It is connected to the first motor 32, the second motor 54 and the pressure sensor 345 through wires. The power supply is an external 220V AC power supply, which is converted into 24V and 5V DC power supply through the power module to power the motor, controller and sensor respectively.
