[0002] The raw materials used in the production of insulated wires are generally metal and thermoplastic resin. Among them, the metal is generally copper, and the thermoplastic resin includes PEEK granules. The raw materials are relatively expensive, and the production cost is very high. In the actual production process of insulated wires, defective products will definitely be produced. However, the direct recycling value of defective products is relatively low, and they cannot be directly recycled.

[0003] As we all know, metal conductors such as copper and thermoplastic resin layers such as PEEK can be recycled and reused, and the recycling value is relatively high. It can not only reduce production costs, but also realize the use value of copper and PEEK products again, achieve green energy saving and environmental protection, and fully meet the requirements of the automotive industry. For example, the PEEK insulation layer of the PEEK wire can be stripped, and it is very valuable and meaningful to separate the PEEK from the PEEK wire.

[0004] Existing stripping methods have relatively large defects. Chemical stripping method: high risk of operation, very slow stripping efficiency, the resin layer will be wasted and melted in the chemicals and cannot be reused. Mechanical stripping method, including mold method: high mold or tool loss, high mold or tool precision requirements, more manpower required, and difficult operation, easy to strip out the metal substrate to contaminate the resin layer.

[0005] Therefore, how to provide a stripping device for the resin layer of an insulated wire material that can improve the stripping efficiency and ensure that the conductor and the resin layer can be completely and cleanly separated after stripping is a problem that urgently needs to be solved.

[0026] Many specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation disclosed below.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] The solution provided by the utility model is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0029] refer to Figures 1 to 5 As shown, the present embodiment provides a device for stripping the resin layer of an insulating wire, and the stripping device specifically strips the resin layer 110 in the insulating wire 100, that is, separates the resin layer 110 from the conductor 120 wrapped in the resin layer 110, so that the resin layer 110 and the conductor 120 are recycled separately, wherein the resin layer 110 is a thermoplastic resin such as polyetheretherketone (PEEK), and the conductor 120 is a material such as metallic copper.

[0030] Specifically, the stripping device includes a wire unwinding machine 1, a first tensioning machine 2, a preheating machine 3, a paint stripping machine 4, a second tensioning machine 5 and a wire taking-up machine 6 which are arranged in sequence; the preheating machine 3 is provided with a preheating tube 31 for the insulating wire 100 to pass through and preheat it, the paint stripping machine 4 is provided with a paint stripping mold 41, the paint stripping mold 41 includes a mold sleeve 411, a mold core 412 and a heating element 413, the mold sleeve 411 is provided with a mold core mounting groove 411a, a wire passing hole 411b and a heating element mounting groove 411c, the mold core mounting groove 411a and the wire passing hole 411b are interconnected, the mold core 412 is installed in the mold core mounting groove 411a, and the front end portion of the mold core 412 protrudes from the mold core mounting groove 411a, which is used to strip the resin layer 110 of the insulating wire 100, and the heating element 413 is installed in the heating element mounting groove 411c.

[0031] Among them, the wire-releasing machine 1 is used to release the insulating wire 100 that needs to be recycled; the first tension machine 2 and the second tension machine 5 are used to tighten the wire for easy routing and processing; the wire-receiving machine 6 is used to wind and tighten the conductor 120 after stripping the resin layer 110; the outlet end of the preheating tube 31 can extend to the inlet end of the mold core 412, reducing the distance between the preheating tube 31 and the mold core 412, which can avoid the temperature of the preheated insulating wire from dropping too much and ensure the preheating effect; the preheating tube 31 can be heated and heated by hot air or high-frequency induction components, or a heating sleeve; the mold core installation groove 411a is opened at the center of the mold sleeve 411. In this embodiment, the mold core 412 can be detachably installed in the mold core installation groove 411a, which is convenient for later maintenance and replacement operations.

[0032] See also Figure 5 As can be understood, a through core hole 412a is also provided in the core 412. The size of the front end of the core hole 412a is adapted to the conductor 120 of the insulated wire 100, that is, only the conductor 120 is allowed to enter, and the resin layer 110 will be stripped at the entrance of the core hole 412a. To improve the stripping effect, a first chamfer a is formed at the front end of the core 412, that is, at the outer periphery of the front end of the core hole 412a. The first chamfer a can form a sharp scraper to continuously scrape off the resin layer 110; a second chamfer b is provided at the end of the core hole 412a. The second chamfer b can leave an appropriate space for the conductor 120 to prevent excessive friction between the conductor 120 and the core hole 412a, thereby facilitating the movement and passage of the conductor 120.

[0033] In this embodiment, a heating element 413 is further provided on the mold sleeve 411, which is used to heat the mold sleeve 411 and the mold core 412, so as to further heat the insulated wire 100, which can further improve the stripping effect; the overall stripping equipment is simple, easy to operate, and has a high stripping efficiency. After stripping, the resin layer 110 and the conductor 120 are highly clean, and the rapid stripping of the resin layer and the metal substrate is fully realized, ensuring the reuse of the resin layer and the metal substrate.

[0034] like Figure 2 and 3 As shown, in some embodiments, a plurality of heating element mounting grooves 411c are provided, and are distributed in a circular array with the core mounting groove 411a as the center. A heating element 413 is provided in each heating element mounting groove 411c, which can make the heating more uniform and ensure the heating effect. In this embodiment, the heating element 413 is a heating rod, which is heated by the heating rod, is easy to control, and is convenient to install.

[0035] Furthermore, in order to achieve precise temperature control, in some embodiments, a temperature measuring element 414 is also provided on the mold sleeve 411. The temperature measuring element 414 can be a thermocouple, which is used to measure the heating temperature of the heating element 413 to keep it within a preset temperature range. It can be understood that the temperature measuring element 414 can also be provided on the preheating tube 31 to measure the heating temperature of the preheating tube 31.

[0036] In this embodiment, the heating temperature of the preheating tube 31 is 300°C-500°C, preferably 300°C-400°C; the heating temperature of the heating element 413 is 400°C-600°C; the melting point of the resin layer 110 in the insulating wire 100 is generally 343°, and it is softened in advance under the treatment of the preheating tube 31, and then under the treatment of the heating element 413 in the paint stripping mold 41, since the heating temperature of the heating element 413 is 400°C-600°C, when the insulating wire 100 passes through the paint stripping machine 4, the resin layer 110 directly melts and flows out from the surface of the conductor 120, and then through the treatment of the mold core 412, the residual resin layer 110 can be further scraped off, reducing the loss of the mold core 412 and extending its service life.

[0037] like Figure 1 As shown, a collecting frame 7 is also provided at the lower part of the front end of the paint stripping machine 4, and the inlet end of the mold core 412 is located directly above the collecting frame 7, which is used to collect the separated melted resin layer; further, in this embodiment, the outlet end of the preheating tube 31 is also located directly above the collecting frame 7, so that part of the resin layer 110 melted in the preheating tube 31 can also be directly collected in the collecting frame 7.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
