Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of copper foil winding equipment, and specifically relates to a seamless pipe winding copper foil device. BACKGROUND

[0002] Copper foil is a kind of metal foil material with fine fluff or rough surface. The special surface treatment can increase the contact area and adhesion with active material when used as current collector in the field of electrochemical energy storage, especially in battery manufacturing, thereby improving battery performance. In the processing of copper foil, collection and winding is a crucial step, which directly affects the quality of the product and the subsequent application effect.

[0003] Traditional copper foil winding method uses roller shaft, but this method has some limitations, such as it may cause damage to the surface of the foil, or lead to uneven winding. Using seamless pipe instead of roller shaft for copper foil winding can effectively reduce these defects. The surface of seamless pipe is smooth, and the friction coefficient is low when it contacts with copper foil, which helps to reduce the surface damage of copper foil during winding and maintain its surface properties. At the same time, the uniformity and rigidity of seamless pipe are superior to traditional roller shaft, which can provide more uniform winding force and reduce the deformation or damage of foil caused by uneven pressure.

[0004] In addition, the high strength and high rigidity of seamless pipe enable it to withstand greater tension during winding, which is beneficial to maintain the mechanical properties of copper foil, especially at high speed. Seamless pipe winding can also reduce the vertical rib or vertical line phenomenon of copper foil during winding, making the wound copper foil more flat and improving the quality of copper foil winding. Practice shows that after using seamless pipe winding, the amount of copper foil judged as substandard due to vertical rib and vertical line is significantly reduced, thereby improving the quality of copper foil winding and achieving good economic benefits.

[0005] Moreover, in the winding process of copper foil, accurate tension control is essential to ensure the uniformity of winding and the integrity of copper foil. In addition, the dryness of the surface of copper foil is also crucial, as it is directly related to the generation of static electricity and oxidation. When the matte surface of copper foil is closely attached to the smooth surface after winding, if there is moisture on the surface, the generation of static electricity will be intensified, which not only increases the risk of electrochemical reaction, but also may cause corrosion and oxidation of the edge part of the copper foil smooth surface. This oxidation will seriously affect the overall quality of copper foil, and thus affect its performance in subsequent applications.

[0006] To address this issue, it's essential to thoroughly dry the foil before winding. Drying the foil reduces static electricity, as moisture is a contributing factor. Furthermore, drying the foil effectively prevents oxidation caused by moisture, protecting it from corrosion and oxidation. During the winding process, heating can be used to promote evaporation of moisture from the foil surface, reducing the moisture content in the air and minimizing the potential risks of static electricity and oxidation.

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original foil winding device. Utility Model Content

[0008] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a seamless tube foil rolling device that is significantly different from the existing technology to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seamless tube foil rolling device, comprising a base, a fixed frame and a movable frame are respectively provided on both sides of the top of the base, and an air expansion shaft is installed on each side of the fixed frame and the movable frame close to each other, the air expansion shaft on the fixed frame is connected to a drive motor through a sprocket and a chain, and the drive motor is installed on the outer wall of the fixed frame, and the output end of the drive motor passes through the fixed frame and is connected to a bevel gear set, the bevel gear set is connected to a heating structure, and the heating structure is provided on the base, and the heating structure is connected to the mounting structure, the mounting structures are respectively installed on the fixed frame and the movable frame and are located below the air expansion shaft, and a seamless tube body for rolling the foil is installed between the mounting structures.

[0011] Preferably, the diameter of the bevel gear of the bevel gear set connected to the drive motor is larger than the diameter of the bevel gear connected to the heating structure.

[0012] Preferably, the heating structure includes an air cavity, a vertical shaft, a fan blade, a heating device, a delivery pipe and an output pipe. An air cavity is opened in the base, and one end of the air cavity is rotatably connected to the vertical shaft. The outer wall of the vertical shaft is installed with a fan blade, and the upper end of the vertical shaft passes through the top of the base and is connected to a bevel gear set. The other end of the air cavity is connected to the heating device, and the heating device is provided with an output pipe, and the output pipe is connected to the mounting structure on the movable frame, the mounting structure on the fixed frame is connected to the delivery pipe, and the delivery pipe is connected to the air cavity at one end of the fan blade.

[0013] Preferably, the mounting structure includes an L-shaped mounting frame, a mounting port and a cavity, and an L-shaped mounting frame is connected to each of the fixed frame and the movable frame, and a mounting port that passes through the two end faces is opened in the vertical area of ​​each L-shaped mounting frame, and a seamless tube body is installed in the mounting port, and a cavity is opened in each of the mounting ports, and a shaft seal is installed between the two sides of each mounting port and the seamless tube body.

[0014] Preferably, the seamless tube body includes a fixed port, a flow cavity, a baffle and an air hole. A fixed port for connecting to an air expansion shaft is provided at each end of the seamless tube body, and a flow cavity is provided inside the seamless tube body, and a number of baffles for slowing down the flow are distributed at equal intervals in a zigzag manner in the flow cavity. A number of air holes that penetrate the outer wall of the seamless tube body and contact the cavity are provided at both ends of the flow cavity.

[0015] Compared with the existing technology, the present invention has the following beneficial effects: the seamless tube foil winding device, through the coordinated operation of key components such as the fixed frame, movable frame, air expansion shaft and mounting structure, can quickly clamp and fix the seamless tube body, ensuring the stability and reliability of the winding process. The intervention of the drive motor causes the seamless tube body to rotate, thereby efficiently achieving the foil winding operation. In addition, shaft seals are provided between the seamless tube body and both sides of the mounting opening on the L-shaped mounting frame, which does not affect the rotation of the seamless tube body while improving its sealing performance.

[0016] Furthermore, the device plays a vital role in the winding process through the ingenious coordination of the bevel gear set, heating structure, and mounting structure. The auxiliary linkage of the bevel gear set enables the device to transport the liquid or gas heated by the heating equipment into the seamless tube body through the air cavity and conveying pipe without the need for an additional power source. Heat is transferred to the wound foil through heat conduction, which not only quickly evaporates moisture from the foil surface but also effectively reduces the humidity in the surrounding air, thereby mitigating the adverse effects of moisture on foil winding. This humidity control is crucial to the quality of the foil, as moisture can not only cause the foil to stick or damage but also cause static electricity problems.

[0017] Furthermore, as the liquid flows, the device absorbs static electricity generated on the fleece during the winding process. This static electricity is transported along with the liquid through the outlet pipe to the heating equipment and ultimately safely discharged to the ground, significantly reducing the impact of static electricity on the fleece winding process. This reduction not only helps protect the fleece from electrochemical corrosion but also reduces the risk of fire and explosion caused by static discharge, thereby enhancing the safety of the entire winding process.

[0018] This innovative technology improves the safety of the production environment by reducing the generation and accumulation of static electricity. Therefore, this seamless tube foil winding device optimizes the production process and ensures high product standards and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
