Description

Technical Field

[0001] This utility model relates to the field of foil winding, and in particular to an extrusion-type carbon-coated aluminum foil winding device. Background Technology

[0002] In the winding process of carbon-coated aluminum foil, reverse rotation pull-out winding is currently the mainstream method (see...). Figure 1 (Diagram of traditional solution). The core structure of this method includes: Active rotating take-up roller 2: driven by a motor, it pulls out the foil by rotating in the opposite direction; Guide roller system ( Figure 1 The intermediate roll group includes the first process roll 5, the second process roll 8, the third process roll 9, and the fourth process roll 10: it only serves the functions of steering and support; Tension control system: The motor speed is adjusted by feedback from the swing roller 7 and the tension roller 6.

[0003] This winding method makes it easy for air to enter during the winding process, causing the carbon-coated side to be thicker than the uncoated side (i.e., the un-carbon-coated side), forming radial wrinkles. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion-type carbon-coated aluminum foil winding device that transforms passive winding into active extrusion and degassing. By combining the swing arm and pressure roller, it specifically solves the problem of blank areas caused by thickness differences in carbon-coated aluminum foil, while maintaining stable winding tension. It is both practical and scalable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An extrusion-type carbon-coated aluminum foil winding device includes a swing arm, the swing end of which is connected to a winding roller; a pressure roller is provided diagonally below the winding roller; and a power unit for driving the swing arm to swing is connected to the middle of the swing arm.

[0006] A further embodiment: A first process roller and a tension roller are sequentially arranged on one side of the pressure roller. The position of the first process roller is set higher than the height of the pressure roller and the tension roller, and the axes of the first process roller, the pressure roller and the tension roller are connected to form a triangle.

[0007] A further solution includes a swing roller; the straight line formed by the connection between the swing roller and the tension roller is the first straight line, and the straight line formed by the connection between the first process roller and the tension roller is the second straight line. Then, the angle between the first straight line and the second straight line is not greater than 90°.

[0008] Further solutions include a second process roller located between the first process roller and the tension roller, a third process roller located between the swing roller and the tension roller, and a fourth process roller located at the rear end of the swing roller.

[0009] A further option: the pressure roller is a rubber roller.

[0010] A further option: the power unit is a telescopic cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a swing arm to suspend the take-up roller, and adds a pressure roller diagonally below the take-up roller. The pressure roller compresses and vents the aluminum foil during the winding process, preventing wrinkles and collapse. As the winding diameter of the take-up roller increases, the pressure between the pressure roller and the take-up roller is adjusted via a telescopic cylinder to ensure effective compression. The pressure roller is made of a gel material with a certain degree of elastic deformation, resulting in better contact with the take-up roller and improved compression of excess air. Furthermore, the elastic roller surface prevents indentations on the aluminum foil surface. Attached Figure Description

Detailed Implementation

[0013] 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.

[0014] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] Please see Figure 2An extrusion-type carbon-coated aluminum foil winding device includes a swing arm 1, with a winding roller 2 connected to the swinging end of the swing arm 1; a pressure roller 3 is located diagonally below the winding roller 2; and a power unit 4 for driving the swing arm 1 to swing is connected to the middle of the swing arm 1. The winding roller 2 is located diagonally above the pressure roller 3. The gravity of the winding roller 2 is decomposed into normal pressure (enhancing adhesion) and tangential force (balanced by friction), eliminating radial runout during the winding process and having a gravity self-locking anti-shake function. The winding roller 2 has its own motor to achieve uniform self-rotation. The power unit 4 pushes the swing arm 1, driving the swing arm 1 to swing. Through a preset thrust-time variation curve, the distance between the pressure roller 3 and the winding roller 2 is dynamically adjusted as the winding roller diameter increases, maintaining a constant contact pressure to achieve continuous air exhaust. The swinging end of the swing arm 1 and the power unit 4 are both mounted on the frame 11 at both ends of the winding device.

[0016] Furthermore, a first process roller 5 and a tension roller 6 are sequentially arranged on one side of the pressure roller 3. The position of the first process roller 5 is set higher than the height of the pressure roller 3 and the tension roller 6. The axis connection of the first process roller 5, the pressure roller 3 and the tension roller 6 forms a triangular tension buffer zone. After the aluminum foil 12 is pre-tensioned by the high-position first process roller 5, it is slack eliminated before entering the pressure roller 3, reducing the tension fluctuation range. The high-position first process roller 5 forces the aluminum foil 12 to cut into the pressure roller 3 at a large angle, extending the exhaust path.

[0017] Furthermore, it also includes a swing roller 7; the straight line formed by the connection between the swing roller 7 and the tension roller 6 is the first straight line, and the straight line formed by the connection between the first process roller 5 and the tension roller 6 is the second straight line. The angle between the first and second straight lines is no greater than 90°, and this acute angle can shorten the tension delay time. The tension roller 6 can measure the process tension of the aluminum foil, and the swing roller 7 can control the tension magnitude through its radial back-and-forth oscillation. The tension roller 6 and the swing roller 7 can also achieve real-time correction of aluminum foil conveying.

[0018] Furthermore, it also includes a second process roller 8 located between the first process roller 5 and the tension roller 6, a third process roller 9 located between the swing roller 7 and the tension roller 6, and a fourth process roller 10 located at the rear end of the swing roller 7. The second process roller 8 is used to support the span between the first process roller 5 and the tension roller 6, and to suppress the sagging of the aluminum foil in the middle; the third process roller 9 is used to isolate the vibration of the swing roller 7 and the tension roller 6, and to avoid mutual interference between the tension roller 6 and the swing roller 7; the fourth process roller 10 connects to the upstream equipment to ensure the output level.

[0019] Furthermore, the pressure roller 3 is a rubber roller. The rubber layer (preferably polyurethane) deforms under pressure, resulting in a higher gas extrusion rate compared to a metal roller. In addition, the surface of the colloidal aluminum foil has a cushioning effect, preventing indentations.

[0020] Furthermore, the power unit 4 is a telescopic cylinder. This telescopic cylinder includes a cam mechanism and a stroke valve. By presetting the cam profile, the telescopic amount can be automatically adjusted according to the change in roll diameter, without the need for additional sensors or software programs.

[0021] In operation, the aluminum foil is wound up sequentially through the fourth process roller 10 → swing roller 7 → third process roller 9 → tension roller 6 → second process roller 8 → first process roller 5 → pressure roller 3 → take-up roller 2. As the diameter of the take-up roller 2 increases, the preset stroke adjustment of the telescopic cylinder extends synchronously to ensure that the pressure between the pressure roller and the take-up roller is within a certain constant range.

[0022] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0023] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
