Description

Technical Field

[0001] This disclosure relates to the field of aluminum foil processing technology, and in particular to an aluminum foil guiding device. Background Technology

[0002] In aluminum foil processing, bending performance is one of the key technical indicators for measuring product quality, directly affecting product quality and reliability. However, in traditional chemical formation processes, aluminum foil suffers from uneven bending and easy breakage, leading to unstable product quality and failing to meet the demands of high-precision, high-quality production. Utility Model Content

[0003] This disclosure provides an aluminum foil guiding device, which includes at least one guiding assembly. The guiding assembly includes a pair of discs, two guiding shafts, and two rollers. The two rollers are respectively sleeved on the two guiding shafts. The two discs are respectively disposed at both ends of the two guiding shafts and are fixedly connected to the guiding shafts. The rotation of the discs drives at least one of the guiding shafts to move around the center of the discs.

[0004] In some embodiments, the two guide shafts are offset from the center of the wheel, and the rotation of the wheel causes the two guide shafts to move simultaneously around the center of the wheel.

[0005] In some embodiments, the wheel corresponds to multiple rotation positions, and the guide assembly bends the aluminum foil at a different angle at each rotation position.

[0006] In some embodiments, the wheel corresponds to a first rotation position and a second rotation position; when the body portion of the aluminum foil passes the guide assembly, the wheel rotates to the first rotation position; when the joint portion of the aluminum foil passes the guide assembly, the wheel rotates to the second rotation position.

[0007] In some embodiments, the guiding assembly further includes a motor coupled to one of the wheels for driving the wheels to rotate.

[0008] In some embodiments, at least one of the discs has a toothed structure on its outer periphery, and the output shaft of the motor has a transmission gear that meshes with the toothed structure.

[0009] In some embodiments, the guiding assembly further includes a thickness sensor disposed on the side where the aluminum foil enters the guiding assembly, for detecting the thickness of the aluminum foil, so as to control the motor to drive the wheel to rotate to the corresponding rotation position according to the thickness of the aluminum foil.

[0010] In some embodiments, the aluminum foil guiding device further includes a pair of limiting brackets for supporting the guiding assembly.

[0011] In some embodiments, the limiting bracket includes a limiting plate with an arc-shaped groove; a pair of limiting plates are disposed between a pair of wheels of the guide assembly, and two guide shafts pass through the arc-shaped groove; or a pair of limiting plates are disposed outside the pair of wheels of the guide assembly, and a limiting bar is disposed outside the wheel, the limiting bar passing through the arc-shaped groove.

[0012] In some embodiments, the guide assembly further includes at least one fixed shaft, which is arranged parallel to the guide shaft and has its two ends fixedly connected to a pair of limiting brackets.

[0013] In this embodiment, the aluminum foil guiding device includes at least one guiding assembly, which includes a pair of discs, two guiding shafts, and two rollers. The two rollers are respectively sleeved on the two guiding shafts, and the two discs are fixedly connected to the guiding shafts. The rotation of the discs drives the guiding shafts to move around the center of the discs. As the rollers move, the bending angle of the aluminum foil passing through the two rollers changes, thus forming an aluminum foil guiding structure with an adjustable bending angle. This is beneficial for meeting the bending requirements of aluminum foils of different thicknesses, improving the bending performance of aluminum foil, and enhancing the versatility and flexibility of the aluminum foil guiding device. At the same time, it can also bend aluminum foil at different angles for different thicknesses of the joint and body, which is beneficial for improving the bending performance and quality stability of aluminum foil, thereby reducing production costs and scrap rates, and improving production efficiency and economic benefits.

[0027] Figure 1 This is a schematic diagram of the aluminum foil guiding device according to an embodiment of the present disclosure.

[0028] Reference Figure 1This disclosure provides an aluminum foil guiding device, including at least one guiding assembly. The guiding assembly includes a pair of discs 1, two guiding shafts 2, and two rollers. The two rollers are respectively sleeved on the two guiding shafts 2. The two discs 1 are respectively disposed at both ends of the two guiding shafts 2 and are fixedly connected to the guiding shafts 2. The rotation of the discs 1 drives at least one guiding shaft 2 to move around the center of the discs 1.

[0029] In this embodiment, at least one guide shaft 2 is offset from the center of the wheel 1. When the wheel 1 rotates around its center, it drives at least one guide shaft 2 (i.e., at least one roller) to move around the center of the wheel 1. As the position of the roller changes, the bending angle of the aluminum foil guided by the two rollers also changes, thereby forming a guide structure that can adjust the bending angle of the aluminum foil.

[0030] The bending performance of aluminum foil refers not only to its ability to withstand repeated bending during use, but also to its ability to withstand bending during processing without developing microcracks, wrinkles, or surface damage. Aluminum foils of different thicknesses have varying stiffness and ductility, resulting in different bending responses. For example, thicker aluminum foils are more rigid and less flexible; if the bending radius is too small, surface cracking or uneven plastic deformation can easily occur. Thinner aluminum foils, on the other hand, are more flexible but have lower strength and are prone to wrinkling and folding. Therefore, setting different bending angles for aluminum foils of different thicknesses allows for stress adaptation and deformation optimization, thereby protecting the structural integrity of the aluminum foil and improving its bending performance.

[0031] The guide structure provided in this embodiment, which is capable of adjusting the bending angle of aluminum foil, can set different bending angles for aluminum foils of different thicknesses, thereby achieving the adaptation of the bending angle to the aluminum foil thickness. This is beneficial for meeting the bending requirements of aluminum foils of different specifications, improving the bending performance of aluminum foil, and enhancing the versatility and flexibility of the aluminum foil guide device.

[0032] Furthermore, in the aluminum foil processing, aluminum foil can be divided into a joint section and a body section. The joint section refers to the segment where two independent sections of aluminum foil are connected due to rewinding, tape breakage, or other process requirements; the body section refers to a uniform segment without interruption or connection. The thickness of the aluminum foil at the joint section is generally different from that of the body section. For example, the joint section of aluminum foil refers to the overlapping portion where the end of one roll of aluminum foil connects to the beginning of another roll, while the body section refers to the unconnected overlapping portion outside the beginning and end of each roll. The thickness of the joint section is greater than the thickness of the body section; for example, the thickness of the joint section is twice the thickness of the body section.

[0033] By utilizing the guide structure provided in this embodiment that can adjust the bending angle of aluminum foil, when the joint and the body pass through the guide assembly, the head and the body can be bent at different angles by adjusting the position of the rollers, thereby achieving the adaptation of different thicknesses and bending angles of the joint and the body, which is beneficial to improving the bending performance of the aluminum foil joint and the body.

[0034] The aluminum foil guiding device provided in this embodiment has an adjustable roller position, which can meet the bending requirements of aluminum foil of different thicknesses. It realizes the adaptation of aluminum foil thickness and bending angle, which is beneficial to improve the bending performance of aluminum foil, thereby reducing production costs and scrap rate, and improving production efficiency and economic benefits.

[0035] In this embodiment, the wheel 1 can be driven to rotate manually or by a motor or the like. This embodiment does not impose any special limitations on this.

[0036] In some embodiments, one guide shaft 2 is offset from the center of the wheel 1, and the other guide shaft 2 is coaxial with the center of the wheel 1. The rotation of the wheel 1 drives the eccentrically positioned guide shaft 2 to move around the center of the wheel 1 to change the spatial position of the guide shaft 2. When the aluminum foil passes through the guide assembly, the bending angle changes to form a specific bending angle.

[0037] In some embodiments, the two guide shafts 2 are offset from the center of the wheel 1, and the rotation of the wheel 1 causes the two guide shafts 2 to move simultaneously around the center of the wheel 1.

[0038] In this embodiment of the present disclosure, the two guide shafts 2 (i.e., two rollers) move simultaneously with the rotation of the wheel 1, which enables the aluminum foil passing through the guide assembly to maintain a consistent bending angle at each bending position.

[0039] In some embodiments, the wheel 1 corresponds to multiple rotation positions, and each rotation position causes the aluminum foil to bend at a different angle.

[0040] In the embodiments disclosed herein, multiple rotation positions are adapted to various aluminum foils of different specifications, which can meet the bending requirements of aluminum foils of different specifications.

[0041] In the embodiments of this disclosure, multiple rotational positions are set by means of marking, positioning structures, or rotation angles (number of revolutions) of motors, etc. This disclosure does not impose any special limitations on this aspect.

[0042] Due to the presence of the aluminum foil body and the connector, in some embodiments, multiple rotation positions are arranged in pairs, each pair of rotation positions corresponding to a certain specification of aluminum foil; the two rotation positions in a pair of rotation positions correspond to the connector and the body, respectively. When processing an aluminum foil of a certain specification, when the connector passes the guide assembly, the wheel 1 is rotated to one position; when the body passes the guide assembly, the wheel 1 is rotated to another position.

[0043] In some embodiments, the wheel 1 corresponds to a first rotation position and a second rotation position; when the body portion of the aluminum foil passes the guide assembly, the wheel 1 rotates to the first rotation position; when the joint portion of the aluminum foil passes the guide assembly, the wheel 1 rotates to the second rotation position.

[0044] In some embodiments, each specification of aluminum foil corresponds to a specific pair of rotational positions on the wheel 1, namely a first rotational position and a second rotational position. Therefore, when the connector and body pass through the guide assembly, the consistency and accuracy of the bending angle adjustment for aluminum foil of a specific specification can be ensured. Bending the connector and body at different angles allows for the adaptation of different thicknesses and bending angles between the connector and body, which is beneficial for improving the bending performance of the aluminum foil connector and body, thereby improving production quality and efficiency.

[0045] In some embodiments, such as Figure 1 , Figure 2 As shown, the guide assembly also includes a motor 4, which is coupled to one of the discs 1 and drives the disc 1 to rotate. The motor 4 transmits power to the guide shaft 2 and rollers through the disc 1, so that the guide shaft 2 moves around the center of the disc 1 to guide the aluminum foil bending.

[0046] This disclosure does not impose any special limitations on how the motor 4 is coupled to the wheel 1. For example, the output shaft of the motor 4 can be directly and fixedly connected to the center position of the wheel 1, and the motor 4 can directly drive the wheel 1 to rotate. The motor 4 can also be connected to the wheel 1 through gear meshing or other means.

[0047] In some embodiments, such as Figure 1 , Figure 2 As shown, at least one wheel 1 has a toothed structure on its outer periphery, and a transmission gear 11 is provided on the output shaft of the motor 4, meshing with the toothed structure. For example, the wheel 1 located on the same side as the motor 4 has a toothed structure on its outer periphery, the wheel 1 is gear-shaped, and the transmission gear 11 is provided on the output shaft of the motor 4. The transmission gear 11 receives the power output by the motor 4 and transmits the power of the motor 4 to the guide shaft 2 and the rollers by meshing with the toothed structure of the wheel 1.

[0048] In this embodiment of the disclosure, since the aluminum foil typically has a high tension, the small-sized transmission gear 11 meshes with the toothed structure of the large-sized wheel 1, which can provide a stable high torque, which is beneficial for driving the wheel 1 to rotate and maintain stability.

[0049] In some embodiments, such as Figure 3 As shown, the guide assembly also includes a thickness sensor 5, which is located on the side where the aluminum foil enters the guide assembly. The thickness sensor 5 is used to detect the thickness of the aluminum foil so as to control the motor 4 to drive the wheel 1 to rotate to the corresponding rotation position according to the thickness of the aluminum foil.

[0050] In this embodiment, the thickness sensor functions as a high-precision position sensor, capable of detecting the position of the aluminum foil entering the guide assembly, i.e., whether it is the connector or the body, thereby accurately controlling the bending angle. This embodiment does not impose any special limitations on the type of thickness sensor; for example, it can be an ultrasonic thickness gauge, a capacitive thin-film probe, a laser rangefinder, etc.

[0051] In some embodiments, such as Figure 4 As shown, Figure 4 This is a top view of the thickness sensor 5, which is groove-shaped. When the aluminum foil enters the guide assembly, it passes through the groove of the thickness sensor 5 to detect the thickness of the aluminum foil. The thickness of the joint of the aluminum foil is different from the thickness of the body. During the process of the aluminum foil passing through the guide assembly, the thickness sensor 5 controls the rotation of the motor 4 by detecting the change in the thickness of the aluminum foil, so as to drive the wheel 1 to rotate to the first rotation position or the second rotation position.

[0052] In this embodiment of the disclosure, a correspondence can be established between the thickness of aluminum foil of different specifications, the thickness of the joint and the body of aluminum foil of the same specifications, and the rotation angle (number of revolutions) of the motor 4, so that the motor 4 can easily drive the wheel 1 to rotate to the corresponding position.

[0053] In some embodiments, the aluminum foil guiding device provided in this disclosure is installed in a processing tank. This disclosure does not specifically limit the processing tank. In some embodiments, refer to... Figure 2 The embodiments disclosed herein are intended to be installed above the cleaning tank 3. In some embodiments, the aluminum foil guide device is installed above the cleaning tank 3 by means of bolts or the like.

[0054] In some embodiments, the aluminum foil guiding device further includes a pair of limiting brackets 6 for supporting the guiding assembly.

[0055] In some embodiments, the limiting bracket 6 includes a limiting plate 61, on which an arcuate groove 62 is provided. A pair of limiting plates 61 are disposed between a pair of wheel disks 1 of the guide assembly, and two guide shafts 2 are disposed through the arcuate groove 62; or a pair of limiting plates 61 are disposed on the outside of a pair of wheel disks 1 of the guide assembly, and a limiting rod 7 is disposed on the outside of the wheel disk 1, the limiting rod 7 being disposed through the arcuate groove 62.

[0056] In this embodiment, the arc-shaped groove 62 can be one or two corresponding to the two guide shafts 2. This embodiment does not impose any special limitations on this.

[0057] The embodiments disclosed herein do not impose special restrictions on the shape of the limiting plate, such as it can be L-shaped, straight, etc.

[0058] Reference Figure 3 In some embodiments, a pair of limiting plates 61 are disposed on the outer side of a pair of discs 1 of the guide assembly, and a limiting rod 7 is disposed on the outer side of the disc 1, passing through an arc-shaped groove 62. When the disc 1 rotates, the limiting rod 7 moves in the arc-shaped groove 62 as the disc 1 rotates.

[0059] In some embodiments, the guide assembly further includes at least one fixed shaft, which is arranged parallel to the guide shaft 2 and has its two ends fixedly connected to a pair of limiting brackets.

[0060] In some embodiments, the aluminum foil guiding device includes two sets of the above-described guiding components. In some embodiments, each set of guiding components is provided with a thickness sensor on the side where the aluminum foil enters, so that when the aluminum foil enters the two sets of guiding components respectively, the thickness of the aluminum foil can be detected, so as to control the motor 4 to drive the wheel 1 to rotate to the corresponding rotation position according to the thickness of the aluminum foil.

[0061] In some embodiments, the motors of the two sets of guide components are synchronously controlled, thereby causing the discs of the two sets of guide components to rotate synchronously, which in turn drives the rollers of the two sets of guide components to move synchronously.

[0062] To enable those skilled in the art to more clearly understand the technical solutions provided by the embodiments of this disclosure, the technical solutions provided by the embodiments of this disclosure will be described in detail below through specific embodiments:

[0063] In the following embodiments, the aluminum foil guiding device is used in conjunction with the cleaning tank in the aluminum foil processing process.

The outer circumference of the discs 1 has a toothed structure, forming a gear shape. The output shaft of the motor 4 is arranged parallel to the guiding shafts 2. Two transmission gears 11 are set on the output shaft of the motor 4. The two transmission gears 11 mesh with the toothed structure of the two discs 1 respectively, thereby coupling the discs 1 and the motor 4. The thickness sensor 5 is set on the side where the aluminum foil enters the guiding components.

[0066] The roulette wheel 1 has two rotation positions: the first rotation position and the second rotation position.

[0067] The aluminum foil guiding device is installed above the cleaning tank, and its specific operation process is as follows:

[0068] When the body of the aluminum foil enters the guide assembly, the thickness sensor 5 detects the thickness of the body of the aluminum foil, controls the motor 4 to rotate, drives the wheel 1 to rotate to the first rotation position, and the two guide shafts 2 (rollers) move at the same time, so that the body of the aluminum foil is bent at a bending angle adapted to the thickness.

[0069] When the joint of the aluminum foil enters the guide assembly, the thickness sensor 5 detects the thickness of the joint of the aluminum foil, controls the motor 4 to rotate, drives the wheel 1 to rotate to the second rotation position, and the two guide shafts 2 (rollers) move at the same time, so that the joint of the aluminum foil is bent at a bending angle that matches the thickness.

[0070] During the aluminum foil processing, the above-mentioned detection and control process is repeated continuously, and the joint head and body are bent at different angles to achieve the adaptation of different thicknesses and bending angles of the joint head and body, which is beneficial to improving the bending performance of the aluminum foil joint head and body.

Each set of guiding assemblies also includes a fixed shaft, which is parallel to the guiding shaft 2 and its two ends are fixedly connected to the limiting bracket. The fixed shafts of the two sets of guiding assemblies are respectively disposed on the side opposite to the other guiding assembly.

[0073] In this embodiment, the motors 4 of the two sets of guide components can be controlled synchronously to drive the wheel 1 of the two sets of guide components to rotate synchronously, thereby driving the guide shafts 2 (rollers) of the two sets of guide components to move simultaneously; the motors 4 of the two sets of guide components can be controlled independently to drive the wheel 1 of the two sets of guide components to rotate, thereby driving the guide shafts 2 (rollers) of the two sets of guide components to move respectively.

[0074] The aluminum foil guiding device is installed above the cleaning tank. The specific operation process for each guiding assembly is as follows:

[0075] When the body of the aluminum foil enters the guide assembly, the thickness sensor 5 detects the thickness of the body of the aluminum foil, controls the motor 4 to rotate, drives the wheel 1 to rotate to the first rotation position, and the two guide shafts 2 (rollers) move at the same time, so that the body of the aluminum foil is bent at a bending angle adapted to the thickness.

[0076] When the joint of the aluminum foil enters the guide assembly, the thickness sensor 5 detects the thickness of the joint of the aluminum foil, controls the motor 4 to rotate, drives the wheel 1 to rotate to the second rotation position, and the two guide shafts 2 (rollers) move at the same time, so that the joint of the aluminum foil is bent at a bending angle that matches the thickness.
