Description

Technical Field

[0001] This invention relates to the field of cable manufacturing, and in particular to a device for coating conductors with anti-corrosion grease. Background Technology

[0002] Conductors are frequently exposed to complex environments such as rainwater, salt spray, and corrosive gases, making them susceptible to electrochemical corrosion. This leads to decreased conductivity, weakened mechanical strength, and even faults such as breakage and short circuits. Coating the inside of conductors with anti-corrosion grease can effectively isolate corrosive media, improve the operational stability of the circuit, extend the service life of the conductors, and reduce maintenance costs. Currently, during conductor production, anti-corrosion grease coating is mostly done manually or semi-automatically, applying the grease to the surface of the stranded conductors. This often only fills the upper gaps, leaving the lower gaps unfilled, resulting in uneven grease application, significant grease waste, high workload for operators, and low work efficiency.

[0003] Therefore, those skilled in the art are dedicated to developing a wire anti-corrosion grease coating device that is easy to operate and highly automated. Summary of the Invention

[0012] Preferably, the coating mold is provided with at least one support arm, and a brush is connected to the support arm, the brush surface of the brush abutting against the outer surface of the inner layer conductor.

[0013] Preferably, the coating mold is further provided with at least one stirring blade.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for 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 manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figure 1-2 As shown, the present invention provides a wire anti-corrosion grease coating device, including an oil storage ring 1. In this embodiment, the oil storage ring 1 is a hollow ring-shaped reservoir for anti-corrosion grease 6, and a fixing seat 14 is connected to its outer side. The fixing seat 14 is suspended and sleeved on the outside of the single wire 5 to be stranded via a bracket (not shown in the figure), and the bracket and fixing seat 14 provide a mounting base for the oil storage ring 1. A concave annular opening 11 is provided on the inner sidewall of the oil storage ring 1, and an annular baffle 13 matching the shape of the opening is provided at the annular opening 11. The annular baffle 13 is rotatably connected to the oil storage ring 1 via a sealing bearing 12. By providing the sealing bearing 12, the annular baffle 13 can not only reliably seal the annular opening 11 on the oil storage ring 1 during dynamic operation to prevent leakage of the anti-corrosion grease 6 under pressure, but also allow the annular baffle 13 and its connected internal components (such as the coating mold 3 described later) to rotate freely and smoothly relative to the fixed oil storage ring 1. Meanwhile, to facilitate the addition of anti-corrosion grease 6 into the oil storage ring 1, at least one grease injection port 15 is provided on the oil storage ring 1. In this embodiment, two grease injection ports 15 are provided, with the two grease injection ports 15 spaced apart. In other embodiments, other numbers of grease injection ports 15 may be provided according to actual needs.

[0021] At least two oil delivery pipes 2 extending radially are slidably connected to the inner wall of the oil storage ring 1. In this embodiment, four oil delivery pipes 2 are provided, which are evenly distributed circumferentially on the annular baffle 13 and extend radially along the oil storage ring 1. In other embodiments, the number of oil delivery pipes 2 can be selected according to actual needs. In addition, to further connect the oil storage ring 1 and the oil delivery pipes 2, through holes (not shown in the figure) corresponding to the number of oil delivery pipes 2 are provided on the annular baffle 13, and the anti-corrosion grease 6 in the oil storage ring 1 can flow into the oil delivery pipes 2 through the through holes.

[0022] Each oil delivery pipe 2 is connected to a coating mold 3 at the end furthest from the oil storage ring 1. In this embodiment, the coating mold 3 has a hollow design with a working cavity for accommodating the anti-corrosion grease 6. The coating mold 3 is concentrically positioned with the oil storage ring 1 to ensure that the coating mold 3 and the inner conductor 4 remain coaxial, preventing the coating mold 3 from shifting due to rotation and affecting the coating effect. In addition, the design of the coating mold 3 being connected to the oil storage ring 1 through the oil delivery pipe 2 allows the anti-corrosion grease 6 in the oil storage ring 1 to flow radially into the coating mold 3 along the oil delivery pipe 2. In specific implementation, the oil storage ring 1 and the coating mold 3 are located on both sides of the single wires 5 to be stranded, and each oil delivery pipe 2 passes through the gap between two adjacent single wires 5 to be stranded and connects to the coating mold 3. This design cleverly utilizes the existing space of the stranding equipment without occupying additional space. When the distributor disc (not shown in the figure) rotates, it drives each stranded wire 5 to rotate and strand it around the outer side of the inner conductor 4. The rotating stranded wire 5 synchronously pushes each oil delivery pipe 2 passing through its gaps, and then the oil delivery pipe 2 reliably transmits the rotational power to the coating mold 3, causing it to rotate as well. This design uses the stranded wire itself as a drive source to achieve passive rotation of the coating mold 3, eliminating the need for an additional power unit, simplifying the structure and reducing costs.

[0023] Furthermore, the coating mold 3 has a first through hole and a second through hole (not shown in the figure) for the inner layer wire 4 to pass through. The axes of the first through hole and the second through hole coincide, and the inner layer wire 4 passes through the first through hole and the second through hole in sequence. An inlet mold 31 is detachably connected to the first through hole. The inner diameter of the inlet mold 31 matches the outer diameter of the inner layer wire 4 to form a dynamic seal, effectively preventing the anti-corrosion grease 6 in the coating mold 3 from leaking from the inlet end. An outlet mold 32 is also detachably connected to the second through hole. The inner diameter of the outlet mold 32 is larger than the outer diameter of the inner layer wire 4 to form an annular gap between the outlet mold 32 and the inner layer wire 4. This annular gap ensures that a sufficient amount of anti-corrosion grease 6 is carried out by the inner layer wire 4 from the coating mold 3 to fully fill the gaps at the bottom of each strand 5 to be stranded during subsequent stranding. In this embodiment, the annular gap is 1 mm. In other embodiments, the gap can be adjusted according to the actual coating needs. The detachable connection between the inlet mold 31, outlet mold 32, and coating mold 3 is specifically a snap-fit ​​connection in this embodiment. Other embodiments may use other similar connection methods, such as adhesive bonding, magnetic connection, or screw connection, depending on the actual situation. Furthermore, in this embodiment, both the inlet mold 31 and outlet mold 32 employ a half-mold structure in practical applications, made of non-metallic wear-resistant materials such as nylon or bakelite, to avoid scratching the surface of the conductor. The detachable connection design of the inlet mold 31 and outlet mold 32 with the coating mold 3 makes the device highly adaptable. When producing conductors of different specifications, only the inlet mold 31 and outlet mold 32 with the corresponding inner hole size need to be replaced, without replacing the entire coating mold 3, making it both economical and efficient.

[0024] In this embodiment, the coating mold 3 is provided with two support arms 33, which are symmetrically distributed. Each support arm 33 has a brush 33a connected to its distal end away from the coating mold 3, and the brush surface of the brush 33a is in contact with the outer surface of the inner layer conductor 4. When the coating mold 3 rotates, it synchronously drives the brushes 33a at the ends of the two support arms 33 to rotate around the inner layer conductor 4, thereby effectively removing dust and impurities from the surface of the inner layer conductor 4, providing a clean substrate for the subsequent coating of the anti-corrosion grease 6. This significantly improves the adhesion and coating quality of the anti-corrosion grease 6.

[0025] To further improve the flowability of the anti-corrosion grease 6 inside the coating mold 3, two symmetrically arranged stirring blades 34 are also provided inside the coating mold 3. When the coating mold 3 rotates, it drives the stirring blades 34 to stir the anti-corrosion grease 6 inside, so that the anti-corrosion grease 6 is coated more evenly on the surface of the inner conductor 4. At the same time, it can also squeeze the anti-corrosion grease 6, making it more compact.

[0026] This application features a novel structure and simple operation. It utilizes the self-powered stranded wire and employs modular molds that allow for quick replacement, significantly reducing operator workload and increasing production efficiency while exhibiting excellent adaptability and economy. It is suitable for the production of various wire types and specifications. Furthermore, the device is small in size and lightweight, requiring minimal installation space and facilitating production.

[0027] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
