Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil production equipment, and in particular to a device for rewinding and correcting carbon-coated aluminum foil. Background Technology

[0002] Carbon-coated aluminum foil refers to carbon-coated foil made with aluminum foil as the base material. It has advantages such as corrosion resistance, ability to suppress battery polarization, and low production cost, and is widely used in the manufacture of lithium iron phosphate power batteries.

[0003] In the rewinding process of carbon-coated aluminum foil, existing technologies often result in interlayer misalignment of the aluminum foil. If the winding tension in the carbon coating process before the incoming foil is too low, the incoming foil will not be wound tightly, resulting in excessive interlayer gaps and uneven interlayer gaps on both sides. During the rewinding process, the incoming material will rotate under the winding tension, causing loosening. Due to the uneven force on both sides of the foil during winding, the foil will shift to one side as the core rotates. As the winding process progresses, the misalignment gradually worsens, eventually leading to the entire product pulling out of its core.

[0004] Therefore, there is an urgent need to develop a carbon-coated aluminum foil rewinding and correction device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a carbon-coated aluminum foil rewinding and correction device, which can prevent the carbon-coated foil from deepening its misalignment on the core.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A carbon-coated aluminum foil rewinding and correction device is used to address the misalignment of carbon-coated foil on a tube core. The device comprises:

[0008] A support frame having a mounting ring fitted onto the tube core, the support frame being able to be fixedly connected in the gap between the tube core and the carbon-coated foil;

[0010] Optionally, the tensioning assembly further includes a telescopic rod extending radially along the mounting ring, one end of which is connected to the abutment member, and the other end of which passes through the mounting ring. The telescopic rod is capable of reciprocating radially along the mounting ring.

[0011] Optionally, the carbon-coated aluminum foil rewinding and correction device further includes a driving component, the fixed end of which is connected to the support frame, and the output end of which is used to drive the telescopic rod to reciprocate radially along the mounting ring.

[0012] Optionally, the support frame has a mounting plate connected to the mounting ring, the mounting plate and the central axis of the mounting ring are perpendicularly arranged, the fixed end of the driving member is fixedly connected to the mounting plate, and the moving direction of the output end of the driving member is the axial direction of the mounting ring.

[0013] Optionally, a wedge block is provided at the end of the telescopic rod away from the abutment member, the output end of the driving member abuts the inclined surface of the wedge block, and the output end extends to drive the wedge block to move away from the central axis of the mounting ring.

[0014] Optionally, a spring is fitted on the telescopic rod, with one end of the spring abutting against the inner wall of the mounting ring and the other end of the spring abutting against the wedge block. When the abutting member moves away from the central axis of the mounting ring, the spring contracts.

[0015] Optionally, the output end is provided with a roller, and the roller abuts against the inclined surface of the wedge block.

[0016] Optionally, the support frame further includes a support ring connected to the mounting ring. The support ring can be fitted onto the tube core. The support ring is provided with a locking component for locking the tube core and the support ring.

[0019] Beneficial effects:

[0020] This utility model provides a rewinding and correction device for carbonized aluminum foil, used to handle defective carbonized aluminum foil. In the initial stage of misalignment, a support frame is installed in the gap between the core and the carbonized foil. The mounting ring on the support frame provides an installation position for the abutment component.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] During the rewinding process, if the winding tension on the left side is less than that on the right, the carbon-coated foil will misalign on the core. As the foil winds, the outer ring continuously shifts to the left, creating a gap between the foil and the core at the left end. Due to defective incoming material, rewinding can only be done at low speed, reducing production efficiency. If the core pulling phenomenon is severe, the carbon-coated aluminum foil is scrapped, resulting in wasted assembly costs. To prevent further misalignment, this embodiment provides a carbon-coated aluminum foil rewinding correction device.

[0035] See Figure 1 This embodiment provides a carbon-coated aluminum foil rewinding and correction device for addressing misalignment of carbon-coated foil on a tube core. The device includes a support frame 100 and a tensioning assembly 200. The support frame 100 has a mounting ring 110, which is sleeved on the tube core and can be fixedly connected in the gap between the tube core and the carbon-coated foil. The tensioning assembly 200 includes an abutment member 210, which is connected to the mounting ring 110 and arranged circumferentially along the mounting ring 110. The abutment member 210 can reciprocate radially along the mounting ring 110. When the abutment member 210 moves away from the central axis of the tube core, it abuts against the inner ring of the carbon-coated aluminum foil.

[0036] The aforementioned carbonized aluminum foil rewinding and correction device is used to handle defective carbonized aluminum foil. In the initial stage of misalignment, a support frame 100 is installed in the gap between the core and the carbonized foil. The mounting ring 110 on the support frame 100 provides an installation position for the abutment member 210. After the support frame 100 is fixed to the core, the abutment member 210 moves in a direction away from the core's central axis until it abuts against the inner ring of the core, thereby providing tension to the carbonized foil away from the central axis. This effectively prevents the carbonized foil from continuing to shift to one side, effectively improving rewinding efficiency, increasing the yield of carbonized aluminum foil products, reducing raw material loss costs, and ensuring the quality of carbonized aluminum foil rewinding.

[0037] See also Figure 1 During use, the mounting ring 110 and the core are concentrically connected. Three abutment members 210 are provided, equidistantly spaced along the circumference of the mounting ring 110, thus providing uniform tension to the core. Of course, in other embodiments, the number of abutment members 210 can be one, two, four, or five, as long as it provides tension to the carbonized aluminum foil. The specific number of abutment members 210 is not limited here.

[0038] Furthermore, the abutment 210 is an arc-shaped block, and the arc-shaped surface of the arc-shaped block is used to contact the inner ring of the carbon-coated aluminum foil.

[0039] To increase the contact area between the abutment 210 and the inner ring of the carbon-coated aluminum foil, and to make the contact more reliable, in this embodiment, the abutment 210 is set as an arc-shaped block, and the arc-shaped surface of the arc-shaped block contacts the inner ring of the carbon-coated aluminum foil, thereby effectively transmitting tension force. The curvature of the arc-shaped surface is set according to the usage requirements and is not specifically limited here.

[0040] Optionally, the abutment 210 is a rubber pad, and the use of rubber material can effectively prevent the abutment 210 from scratching the carbon-coated aluminum foil.

[0041] Furthermore, the tensioning assembly 200 also includes a telescopic rod 220 extending radially along the mounting ring 110. One end of the telescopic rod 220 is connected to the abutment member 210, and the other end of the telescopic rod 220 passes through the mounting ring 110. The telescopic rod 220 is capable of reciprocating radially along the mounting ring 110.

[0042] In this embodiment, the telescopic rod 220 is movably inserted through the mounting ring 110 to ensure smooth movement of the telescopic rod 220. During the reciprocating movement of the telescopic rod 220 along the mounting ring 110, it will drive the abutment member 210 to move.

[0043] Further, see Figure 1 and Figure 2 The carbon-coated aluminum foil rewinding and correction device also includes a drive unit 300. The fixed end 310 of the drive unit 300 is connected to the support frame 100, and the output end 320 of the drive unit 300 is used to drive the telescopic rod 220 to reciprocate radially along the mounting ring 110.

[0044] In this embodiment, the driving component 300 is a cylinder, a motor, or other components, as long as they can enable the telescopic rod 220 to reciprocate radially along the mounting ring 110.

[0045] Furthermore, the support frame 100 has a mounting plate 120 connected to the mounting ring 110. The central axes of the mounting plate 120 and the mounting ring 110 are perpendicularly arranged. The fixed end 310 of the drive member 300 is fixedly connected to the mounting plate 120, and the moving direction of the output end 320 of the drive member 300 is the axial direction of the mounting ring 110.

[0046] In other embodiments, the moving direction of the output end 320 of the drive component 300 can also be set to the radial direction of the mounting ring 110, specifically according to the structure of the support frame 100. In this embodiment, the drive component 300 is a miniature cylinder, the fixed end 310 refers to the cylinder body, which is fixedly connected to the mounting plate 120, and the output end 320 refers to the cylinder shaft. Controlled by air pressure, the cylinder shaft can reciprocate smoothly and move precisely.

[0047] Furthermore, a wedge block 230 is provided at the end of the telescopic rod 220 away from the abutment member 210. The output end 320 of the driving member 300 abuts against the inclined surface of the wedge block 230. The output end 320 extends out and can drive the wedge block 230 to move away from the central axis of the mounting ring 110.

[0048] By setting the wedge block 230, the output end 320 can provide the telescopic rod 220 with a radial pushing force along the mounting ring 110. When the air pressure is high, the output end 320 extends and contacts the wedge block 230, pushing the wedge block 230 to move away from the central axis of the mounting ring 110, thereby causing the telescopic rod 220 to drive the abutment 210 to approach the carbonized foil.

[0049] Furthermore, a spring 240 is fitted onto the telescopic rod 220. One end of the spring 240 abuts against the inner wall of the mounting ring 110, and the other end of the spring 240 abuts against the wedge block 230. When the abutting member 210 moves away from the central axis of the mounting ring 110, the spring 240 contracts. When the output end 320 moves away from the wedge block 230, the restoring force of the spring 240 causes the abutting member 210 to move closer to the central axis of the mounting ring 110.

[0050] By setting spring 240, when the output end 320 retracts, the restoring force of spring 240 causes the abutment 210 to automatically reset, which is very convenient as it does not require manual control.

[0051] Furthermore, the output end 320 is provided with a roller 321, which abuts against the inclined surface of the wedge block 230.

[0052] The roller 321 ensures smooth transmission and prevents wear caused by direct contact between the wedge block 230 and the output end 320. In other embodiments, the wedge block 230 may be located at the output end 320 of the drive member 300, and the roller 321 may be located on the telescopic rod 220.

[0053] Furthermore, the support frame 100 also includes a support ring 130, which is connected to the mounting ring 110. The support ring 130 can be fitted onto the tube core. A locking component 400 is provided on the support ring 130 to lock the tube core and the support ring 130.

[0054] For example, the support ring 130 is disposed within the inner ring of the mounting ring 110, and is concentric with and spaced apart from the mounting ring 110. By spaced apart, the support ring 130 and the mounting ring 110 provide installation space for the telescopic rod 220. Optionally, the support ring 130 and the mounting ring 110 are connected by a mounting plate 120. See also... Figure 3 To increase the structural strength of the support frame 100, a reinforcing plate 140 is connected before the support ring 130 and the mounting ring 110.

[0055] Furthermore, the locking assembly 400 includes a locking screw 410, which passes radially through the mounting ring 110 and is threadedly connected to the mounting ring 110. One end of the locking screw 410 can abut against the core tube.

[0056] In this embodiment, three sets of locking components 400 are provided, and the three sets of locking components 400 are equally spaced along the circumference of the mounting ring 110, thereby ensuring that the mounting ring 110 is concentric with the tube core. In other embodiments, the number of locking components 400 can be set according to the usage requirements. Further, the locking component 400 also includes locking nuts 420, and two locking nuts 420 are threadedly connected to each locking screw 410. The two locking nuts 420 are located on the inner and outer sides of the mounting ring 110, respectively. The two locking nuts 420 can increase the locking force and prevent the locking screw 410 from moving after it abuts the tube core. Further, a contact portion 430 is provided at the end of the locking screw 410 that abuts the tube core. In this embodiment, the contact portion 430 is circular, which effectively increases the contact area with the tube core and ensures the stability of the connection.

[0057] The usage process of the carbon-coated aluminum foil rewinding and correction device in this embodiment is as follows:

[0058] After the carbonized aluminum foil undergoes misalignment, the support frame 100 is fitted onto the tube core, and the contact part 430 on the locking screw 410 is tightly pressed against the tube core, and the locking nut 420 is tightened, thereby fixing the support frame 100 and the tube core. The miniature cylinder is inflated, causing the cylinder shaft to extend. The roller 321 abuts against the wedge block 230, causing the wedge block 230 to move away from the central axis of the mounting ring 110. At the same time, the spring 240 contracts, and the telescopic rod 220 drives the abutment 210 to approach the inner ring of the carbonized aluminum foil. When the abutment 210 and the inner ring of the carbonized aluminum foil abut, inflation is stopped, and the carbonized aluminum foil continues to be wound. Due to the tension provided by the abutment 210, the carbonized aluminum foil will no longer shift to one side.

[0059] When the winding is complete and the carbon-coated aluminum foil rewinding and correction device needs to be removed, the cylinder shaft is retracted, causing the spring 240 to extend. Under the restoring force of the spring 240, the abutment 210 moves away from the carbon-coated aluminum foil. After the abutment 210 moves away from the carbon-coated aluminum foil, the locking nut 420 is loosened, and the support frame 100 can be removed from the tube core.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
