Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of antioxidant coating devices, specifically an antioxidant coating device for the copper conductor stranding process. Background Technology
[0002] Currently, with increasingly fierce competition in the cable market, the requirements for product quality are becoming more and more stringent. After the three-layer co-extrusion (cross-linking process), copper conductors often react with oxygen under high temperatures, leading to surface oxidation and discoloration, which seriously affects the surface quality of the product. Therefore, solving the problem of oxidation and discoloration after the cross-linking process of copper conductors has become an urgent problem to be solved in the cable industry. At present, to solve the problem of oxidation and discoloration of copper conductors, most cable manufacturers use the method of applying antioxidants to the surface of the copper conductors during the stranding process to form a passivation film on the surface, which plays a role in isolating oxygen during the cross-linking process, thereby reducing or avoiding the occurrence of oxidation reactions.
[0003] Existing methods for applying antioxidants typically include two approaches: one is to apply antioxidants dropwise to the copper wires during the conductor stranding process, before they enter the die; the other is to wrap cotton cloth around the copper conductor after stranding, and apply antioxidants dropwise before or after the cloth is moistened. The copper conductor is then dried with an electric fan after passing through the moistened cloth, ensuring the antioxidants adhere evenly to its surface. However, applying antioxidants dropwise to the copper wires during stranding can lead to uneven application, often resulting in one side having antioxidants while the other side lacks them. When using cotton cloth to wrap the copper conductor, as the antioxidant content on the cloth increases during production, the friction on the cloth increases, making it prone to breakage and potentially introducing antioxidants into the copper conductor, increasing the risk of die jamming and conductor breakage. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an antioxidant coating device for the copper conductor stranding process, in view of the current state of the technology.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An antioxidant coating device for the copper conductor stranding process is provided, used to coat antioxidant onto the copper conductor, comprising:
[0006] The box body has a cavity and a through slot, the through slot being disposed on two opposite sides along the moving direction of the copper conductor;
[0007] An applicator is disposed within the cavity, which is used to accommodate the applicator and the antioxidant. The applicator is used to absorb and retain the antioxidant. When the copper conductor moves relative to the housing, it squeezes the applicator to uniformly coat the copper conductor with antioxidant.
[0008] A cover plate is rotatably mounted on the box body. The cover plate can switch between an open state and a closed state. When the cover plate is in the open state, it is used to allow the copper conductor to be placed into the cavity. When the cover plate is in the closed state, it is used to press the coating material firmly into the cavity.
[0009] In the aforementioned antioxidant coating device for a copper conductor stranding process, the box body has a length, a width, a height, a first abutment part, and a second abutment part. The first abutment part is arranged along the length direction, the second abutment part is arranged along the width direction, and the cover plate has a third abutment part, which is arranged along the height direction. The first abutment part abuts against the coating component to restrict the movement of the coating component along the length direction, the second abutment part abuts against the coating component to restrict the movement of the coating component along the width direction, and the third abutment part movably abuts against the coating component to restrict the movement of the coating component along the height direction.
[0010] In the antioxidant coating device for the copper conductor stranding process described above, the coating material is preferably cotton cloth.
[0011] In the antioxidant coating device for the copper conductor stranding process described above, the through groove has a U-shaped structure.
[0012] In the aforementioned antioxidant coating device for a copper conductor stranding process, the box body has slots on opposite sides and side plates detachably mounted on the slots, with through slots mounted on the side plates.
[0013] In the aforementioned antioxidant coating device for copper conductor stranding process, the cover plate is provided with a buckle, which engages with the box body to limit the position of the cover plate.
[0014] In the aforementioned antioxidant application device for a copper conductor stranding process, the cover plate is provided with a drip inlet, which is connected to the cavity and used to provide the antioxidant to the cavity.
[0015] The antioxidant coating device for the copper conductor stranding process described above is further provided with a support frame. The box body is mounted on the support frame, which is used to support the box body. The support frame is provided with mounting holes.
[0016] Compared with existing technologies, the advantages of this invention lie in that by opening the cover plate and placing the copper conductor into the cavity, and then closing the cover plate, the coating material is pressed firmly into the cavity, ensuring sufficient contact area between the coating material and the copper conductor. The coating material is then moistened with an antioxidant, and the copper conductor is moved relative to the housing. During this movement, the copper conductor compresses the coating material, ensuring the antioxidant is evenly applied to the copper conductor. Throughout this process, the housing restricts the movement of the coating material. Attached Figure Description

Detailed Implementation
[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] like Figures 1 to 2 As shown, this utility model discloses an antioxidant coating device for a copper conductor stranding process, used to coat an antioxidant onto a copper conductor, comprising:
[0022] Box 1 has a cavity 11 and a through groove 12, which are located on opposite sides along the moving direction of the copper conductor. A coating component is located inside the cavity 11, which contains the coating component and an antioxidant. The coating component absorbs and holds the antioxidant. When the copper conductor moves relative to the box 1, it squeezes the coating component to evenly coat the copper conductor with the antioxidant. A cover plate 2 is rotatably mounted on the box 1 and can switch between an open and closed state. When the cover plate 2 is open, it allows the copper conductor to be placed into the cavity 11. When the cover plate 2 is closed, it presses the coating component firmly into the cavity 11.
[0023] When cover 2 is open, the operator can insert the copper conductor into cavity 11, bringing it into contact with the coating component. Then, cover 2 is switched to the closed position, pressing the cover against the coating component and firmly within cavity 11, ensuring sufficient contact area between the coating component and the copper conductor. The coating component is then moistened with antioxidant, and the copper conductor is moved relative to housing 1. During this movement, the copper conductor compresses the coating component, ensuring the antioxidant is evenly applied to it. Throughout this process, housing 1 limits the movement of the coating component, preventing further movement.
[0024] The box body 1 of this solution has a length L, a width W, a height H, a first abutment part 13, and a second abutment part 14. The first abutment part 13 is arranged along the length L direction, and the second abutment part 14 is arranged along the width W direction. The cover plate 2 has a third abutment part 21, which is arranged along the height H direction. The first abutment part 13 abuts against the coating component to restrict the movement of the coating component along the length L direction. The second abutment part 14 abuts against the coating component to restrict the movement of the coating component along the width W direction. The third abutment part 21 abuts against the coating component to restrict the movement of the coating component along the height H direction.
[0025] When the cover plate 2 is closed, the third abutment part 21 abuts against the applicator, thereby restricting the movement of the applicator along the height H direction. When the copper conductor moves relative to the housing 1, the first abutment part 13 abuts against the applicator, restricting the movement of the applicator along the length L direction; the second abutment part 14 abuts against the applicator, restricting the movement of the applicator along the width W direction. This prevents the applicator from being pulled away from the housing 1 by the copper conductor.
[0026] The coating material in this solution is made of cotton cloth. Cotton cloth has excellent absorbency and permeability, enabling it to evenly absorb the antioxidant and, through contact with the copper conductor as it moves, to evenly apply the antioxidant to its surface. This helps ensure that every copper conductor is adequately protected by the antioxidant.
[0027] The through groove 12 in this design has a U-shaped structure. It is simpler to process the through groove 12 into a U-shaped structure, which reduces the number of processing steps and lowers the cost and complexity.
[0028] The box body 1 of this solution has slots on opposite sides and a side plate 15 that can be detachably mounted on the slots. A through groove 12 is mounted on the side plate 15.
[0029] When antioxidants need to be applied to copper conductors of various specifications, the through slot 12 can be set to the required size to accommodate the largest specification of copper conductor produced by the equipment, and side plates 15 with different specifications of through slots 12 can be designed and prepared in advance. In use, the corresponding side plate 15 is selected according to the specific specifications of the copper conductor and inserted into the slot to meet the needs of different specifications of copper conductors.
[0030] The cover plate 2 of this design is equipped with a latch that engages with the box body 1 to limit the position of the cover plate 2. When the cover plate 2 is in the closed state, the latch engages with the box body 1 to limit the position of the cover plate 2, preventing the cotton cloth from being squeezed when the copper conductor moves. This would cause the cotton cloth to push open the cover plate 2, making it impossible for the cover plate 2 to press the cotton cloth tightly, resulting in insufficient contact between the cotton cloth and the copper conductor, and ultimately preventing the antioxidant from being evenly applied to the copper conductor.
[0031] The cover plate 2 of this design is equipped with a drip inlet 22, which communicates with the cavity 11 and is used to provide antioxidant to the cavity 11. The antioxidant is dripped into the cavity 11 through the drip inlet 22, so that the antioxidant drips onto the cotton cloth and wets it. When the cotton cloth is completely wetted, it can apply the antioxidant to the copper conductor surface from all directions, ensuring uniform application.
[0032] This design also includes a support frame 3, on which the box body 1 is mounted. The support frame 3 supports the box body 1 and has mounting holes 31. This application device needs to be installed on a mold base. Bolts pass through the mounting holes 31 and connect to the mold base, thereby fixing the support frame 3 to the mold base. The box body 1 is then mounted on the support frame 3.
[0033] By setting cover plate 2 and opening it, the copper conductor is placed into cavity 11; then cover plate 2 is closed, thus pressing the coating material firmly into cavity 11, ensuring sufficient contact area between the coating material and the copper conductor. The coating material is moistened with antioxidant, and then the copper conductor is moved relative to housing 1. During the movement of the copper conductor, it squeezes the coating material, causing the antioxidant in the coating material to be evenly applied to the copper conductor. During this process, housing 1 limits the movement of the coating material to prevent it from moving.
[0034] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
