[0020] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances. Example

[0021] like Figures 1-3As shown, this utility model proposes a self-adhesive rapid prototyping enameled wire, including a fixing base 1. An enameled wire body 2 is wound around the outside of the fixing base 1. The enameled wire body 2 includes a conductor core 201. An insulating varnish layer 205 is provided on the outside of the conductor core 201. The insulating varnish layer 205 is made of high-strength polyesterimide varnish and is uniformly coated on the surface of the conductor core 201 by dip coating or spraying, with a thickness of 0.01mm. This effectively isolates the conductor core 201 from the outside environment, providing good insulation performance. A self-adhesive hot melt adhesive layer 202 is provided on the outside of the insulating varnish layer 205 to achieve self-adhesive prototyping. The self-adhesive hot melt adhesive layer 202 is made of ethylene-vinyl acetate copolymer hot melt adhesive and is wrapped around the outside of the insulating varnish layer 205 by extrusion coating, with a thickness of 0.03mm. It can melt rapidly under heating conditions, achieving bonding between enameled wires or between the enameled wire and other components. The hot melt adhesive layer 202 is surrounded by a wear-resistant protective layer 203. The wear-resistant protective layer 203 is made of polytetrafluoroethylene and is applied to the outside of the self-adhesive hot melt adhesive layer 202 by coating or wrapping. The thickness is 0.01mm. It can effectively protect the internal self-adhesive hot melt adhesive layer 202 and insulating varnish layer 205, and improve the wear resistance and service life of the enameled wire. The self-adhesive hot melt adhesive layer 202 is surrounded by multiple micro-protrusions 204 to enhance the bonding strength. The micro-protrusions 204 are located between the wear-resistant protective layer 203 and the self-adhesive hot melt adhesive layer 202. The micro-protrusions 204 increase the contact area during bonding. When the hot melt adhesive melts, each particle can act as an independent bonding point, so that when the enameled wire comes into contact with other components, it forms a "multi-point anchoring" effect, making the bonding stronger and improving the bonding effect. It is less likely to loosen or fall off, thus improving product quality. like Figure 4As shown, the top and bottom of the fixed base 1 are provided with limiting rails 3, which are annular. Between the two limiting rails 3, there is a cutting structure 4 for cutting the enameled wire body 2. The cutting structure 4 includes a vertical plate 401 for installation. The top and bottom of the vertical plate 401 are fixedly provided with sliders 402, which are movably connected to the limiting rails 3. The front of the vertical plate 401 is provided with a through groove 403 for the enameled wire body 2 to pass through. One inner wall of the through groove 403 is provided with a through groove 404. A cutter holder 406 for installing a cutter is movably installed in the through groove 404. Two limiting grooves 405 are provided on both inner walls of the through groove 404. Two limiting blocks 407 are fixed on both sides of the cutter holder 406. The limiting blocks 407 are movably connected to the limiting grooves 405. The inner wall of the limiting grooves 405 is provided with springs. Spring 408 applies a pushing force to limit block 407, allowing the blade on one side of blade holder 406 to retract into through groove 404 during non-cutting periods, preventing scratching of the outer surface when pulling the enameled wire body 2. The other end of spring 408 is fixedly connected to limit block 407. A push rod 411 is provided on one side of blade holder 406. A threaded rod 410 is fixedly provided at one end of push rod 411 near blade holder 406. A connecting seat 409 is movably provided on the outside of threaded rod 410. The connecting seat 409 is fixedly connected to blade holder 406. A placement groove 412 is provided on the front of vertical plate 401. The placement groove 412 is used to store push rod 411, which can reduce the space occupied by the equipment. The placement groove 412 and push rod 411 are compatible. Anisotropic magnetic blocks 413 are provided on the inner wall of placement groove 412 and the outside of push rod 411.

[0022] In this embodiment, a self-adhesive hot melt adhesive layer 202 is provided on the outside of the insulating varnish layer 205. This layer can melt rapidly under heating conditions, enabling bonding between enameled wires or between enameled wires and other components. No additional adhesive is needed, simplifying the enameled wire forming process and improving forming efficiency. The micro-protruding particles 204 increase the contact area during bonding. When the hot melt adhesive melts, each particle can act as an independent bonding point, creating a "multi-point anchoring" effect when the enameled wire contacts other components. This makes the bonding stronger, improves the bonding effect, and reduces the likelihood of loosening or detachment, thus improving product quality. When disassembling the enameled wire coil for use, first heat the hot melt adhesive to remelt it. Then, pass one end of the enameled wire through the through slot 403 and pull the wire. The vertical plate 401 can rotate on the fixed seat 1 to follow the real-time position of the enameled wire. When the length of the enameled wire is appropriate, remove the push rod 411 from the placement slot 412, and then install the push rod 411 on the connecting seat 409. Next, press the push rod 411 towards the knife holder 406. The push rod 411 drives the knife holder 406, and the knife holder 406 drives the cutter to cut the enameled wire. The cutting of the enameled wire can be completed without other tools, which improves the cutting efficiency.

[0023] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
