Description

Technical Field

[0001] This invention relates to the field of Litz wire processing equipment technology, specifically to a device suitable for removing the coating from the surface of Litz wire. Background Technology

[0002] During the manufacturing process of Leeds wire, the finished wire undergoes a coating process, typically using polyester film. This coating integrates numerous tiny wire bundles together, providing them with additional mechanical protection, insulation strength, and abrasion resistance. Typically, Leeds wire is wrapped with two or more thin insulating films on its outermost layer to ensure the wire's integrity and performance.

[0003] During the production of Litz wire, some wires need to be sizing twice. Therefore, it is necessary to first remove the insulation film on the surface of the Litz wire. However, the Litz wire is composed of dozens or even hundreds of hair-thin enameled wires. Due to its special structure, the film stripping process must be carried out without damage to avoid damaging the internal core.

[0004] In existing technologies, stripping the insulation film from Litz wire typically involves manual scraping with blades, using general-purpose wire strippers, or immersion in chemical solvents. However, manual scraping relies heavily on the operator's experience; too little force fails to completely remove the insulation film, while excessive force or improper handling can easily cut or damage the internal enameled wire. Conventional wire strippers are designed for single-core or low-core conductors, and their closing gap and shearing force are unsuitable for the soft, multi-strand structure of Litz wire. Furthermore, immersion in chemical solvents is a slow process, and the solvent can easily penetrate the wire's interior through capillary action, corroding the insulation varnish and affecting the overall insulation performance. Therefore, we propose a device suitable for stripping the surface coating from Litz wire. Summary of the Invention

[0005] The purpose of this invention is to provide an apparatus for removing the coating from the surface of Litz wires, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An apparatus for removing coatings from the surface of Leeds lines, comprising a fixing frame; A cutting mechanism for cutting Litz wire; Angle adjustment mechanism, used to adjust the angle of the cutting mechanism; Waste processing facilities are used to handle accumulated waste. The angle adjustment mechanism is mounted on the fixed frame, the cutting mechanism is mounted on the angle adjustment mechanism, and the waste disposal mechanism is mounted on the fixed frame.

[0007] Preferably, the angle adjustment mechanism includes an adjustment seat, which is slidably connected to a fixed frame, and the adjustment seat is connected to a support seat via an adjustment component.

[0008] Preferably, the adjustment assembly includes an adjustment rod 1 movably connected to an adjustment seat, an adjustment block 1 movably connected to the adjustment rod 1, an adjustment rod 2 movably connected to the adjustment block 1, an adjustment block 2 movably connected to the adjustment rod 2, and an adjustment rod 3 movably connected to the adjustment block 2.

[0009] Preferably, adjusting bolts are connected to the adjusting seat, the support seat, the adjusting block one, and the adjusting block two.

[0010] Preferably, the cutting mechanism includes a blade holder, which is fixedly connected to a support base. A clamp is fixedly connected to the bottom end of one side of the blade holder. The clamp has a wedge-shaped structure, and the blade holder has an installation groove.

[0011] Preferably, a cutter is detachably connected inside the mounting groove, the cutter having a right-angled trapezoidal structure, and a mounting block is detachably connected inside the mounting groove. Mounting bolts are engaged with the mounting block, the cutter holder, and the support base.

[0012] Preferably, the waste treatment mechanism includes a support plate, which is slidably connected to a fixed frame, and a guide block is fixedly connected to the support plate. The guide block is a pyramidal structure with one side arc surface.

[0013] Preferably, the guide block has a sliding groove, a peeling block is slidably connected to the guide block, and a positioning bolt is engaged with the peeling block.

[0014] By employing the above technical solution, the present invention provides an apparatus suitable for removing the coating from the surface of Litz wires, which has at least the following beneficial effects: (1) The present invention can accurately cut into the gap between the wire surface and the film by using a cutting blade in conjunction with a front-end shovel-shaped clamp, cutting only the insulating film without damaging the fine enameled wire inside. At the same time, the angle adjustment mechanism can adjust the angle of the cutting mechanism according to the surface condition of the Litz wire, ensuring that the cutting blade is always in the optimal working position. Meanwhile, the key parts of the cutting blade are wrapped by the clamp, which not only ensures the cutting effect but also reduces the risk of scratches and reduces the safety hazards during manual operation.

[0015] (2) The present invention can lock and adjust the cutting mechanism and the angle adjustment mechanism by setting the mounting bolt and the adjusting bolt. At the same time, the mounting bolt and the adjusting bolt are all internal hex bolts, and the operator can complete the angle adjustment by using an internal hex wrench. The operation is simple and intuitive, greatly reducing the dependence on the operator's skills.

[0016] (3) The present invention uses a specially shaped guide block in conjunction with a stripping block to allow waste to be discharged from the bottom along the side of the arc-shaped guide block, which is convenient for centralized collection. At the same time, the design of the fixed block to move back and forth can adapt to different specifications of Litz wire width, improving the equipment versatility. In addition, the cutting mechanism can be used in conjunction with the Litz wire production traction equipment to make the wire stripping process uniform and ensure the consistency of stripping quality.

[0024] It is worth noting that the cutting mechanism 2 includes a blade holder 21 and a cutter 24. The blade holder 21 is fixedly connected to the support base 32. The blade holder 21 is used to install and fix the cutter 24 and to fix the cutter 24 to the support base 32. The cutter 24 is detachably connected to the blade holder 21. A clamp 22 is fixedly connected to one bottom side of the blade holder 21. The clamp 22 has a wedge-shaped structure, and the bottom of the clamp 22 is at the same level as the bottom of the blade holder 21. The clamp 22 can protect the tip of the blade of the internal cutter 24. At the same time, the end of the clamp 22 has an acute angle structure, and the angle of the end of the clamp 22 is less than 30 degrees.
