Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire production technology, and in particular to a wire insulation wrapping device. Background Technology
[0002] In the wire manufacturing process, the insulation wrapping is a crucial step. The quality of the insulation wrapping directly affects the electrical performance, service life, and safety of the wire. The cleanliness of the wire core surface plays a key role in ensuring that the insulation is securely and evenly wrapped around the core.
[0003] Traditional wire insulation wrapping devices have several shortcomings in the core cleaning process. Most devices rely solely on simple wiping tools to clean the core surface, which is insufficient to thoroughly remove oil, dust, and fine metal debris generated during manufacturing. Due to this ineffective cleaning, impurities become trapped between the insulation and the core during wrapping, resulting in a loose bond between them. This reduces the wire's insulation performance, increasing the risk of leakage, short circuits, and other safety hazards, severely impacting the wire's quality and reliability. Utility Model Content
[0004] To overcome the aforementioned drawbacks, this utility model provides a wire insulation wrapping device.
[0005] The technical implementation scheme of this utility model is as follows: a wire insulation wrapping device, comprising a base, a wire feeding assembly, a wire take-up assembly, a heating module, an injection mold, a machine head, a support frame, a rotating block, a cleaning brush, a rotating assembly, and a cooling assembly. The base serves as the basic support structure of the entire device. The wire feeding assembly is installed on the top right side of the base, and the wire take-up assembly is installed on the top left side of the base for winding the processed wire. The heating module and the injection mold are sequentially installed in the middle of the top of the base. The heating module is located on the right side of the injection mold, and the machine head is connected to the left end of the injection mold. The support frame is connected to the top of the base to the right of the heating module. The rotating block is rotatably connected to the upper side of the support frame, and the cleaning brush is connected to the inner side of the rotating block. The cleaning brush has a hollow structure. The cooling assembly is located on the top left side of the base, and the rotating assembly is located on the support frame.
[0006] Furthermore, it is particularly preferred that the hollow structure of the cleaning brush is designed as a multi-layered nested structure, with the inner layer directly contacting the wire core and its inner diameter closely matching the outer diameter of the wire core; the middle layer is equipped with a buffer structure made of elastic rubber material; and the outer layer adopts a reinforced design.
[0007] Furthermore, it is particularly preferred that the rotating assembly includes a motor and gears, with the motor mounted on the right side of the support frame, a gear connected to the motor output shaft, and a gear also connected to the outside of the rotating block, the two gears meshing with each other.
[0008] Furthermore, it is particularly preferred that the cooling assembly includes a water tank and a water pump, with the water tank connected to the top of the base at the left side of the injection mold, slots opened at the left and right ends of the water tank, and a water pump installed at the front of the water tank.
[0009] Furthermore, it is particularly preferred that the device also includes a metal ring and a magnet ring, with the metal ring connected to the right side of the rotating block and the magnet ring attached to the inner side of the metal ring by magnetic adsorption.
[0010] In addition, it is particularly preferred that the device also includes an air pump, a frame, and a filter screen. The air pump is installed on the left side of the support frame, and the frame is connected to the support frame above the air pump. The pipe at the upper end of the air pump is connected to and maintains communication with the frame. The filter screen is installed inside the frame at the point where it communicates with the pipe. The frame is located at the lower left side of the cleaning brush.
[0011] The beneficial effects of this utility model are as follows: 1. The device effectively cleans impurities and small metal debris from the surface of the wire core through the synergistic action of the cleaning brush and the magnetic ring, ensuring that the insulation can be tightly and accurately wrapped around the wire core, thereby improving the quality of the wire product and reducing the probability of problems such as decreased insulation performance and short circuits caused by impurities.
[0012] 2. The cooperation between the wire feeding assembly and the wire take-up assembly enables the wire to be fed at a uniform speed. All components operate synchronously, forming a continuous and efficient processing flow from wire core feeding, cleaning, heating, injection molding to cooling and winding, reducing processing time and improving production efficiency.
[0013] 3. The debris collection system, consisting of an air pump, frame, and filter, prevents debris from scattering randomly during cleaning, keeps the work area clean, reduces the risk of operators inhaling debris, and also reduces the contamination and potential damage of debris to other equipment.
[0014] 4.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0021] Example: A device for wrapping electrical wire insulation, such as Figures 1-4As shown, the device includes a base 1, a wire feeding assembly 2, a wire take-up assembly 3, a heating module 6, an injection mold 7, a machine head 8, a support frame 11, a rotating block 14, a cleaning brush 15, a rotating assembly, and a cooling assembly. The base 1 serves as the fundamental support structure for the entire device. The wire feeding assembly 2 is bolted to its top right side, and this assembly plays a crucial role in driving the wire core winding. The wire core winding is mounted on the wire feeding assembly 2, and a specific driving mechanism ensures stable output of the wire core. The wire take-up assembly 3 is bolted to the top left side of the base 1. After the wire has been wound up, an empty reel is attached to the take-up assembly 3. One end of the wire core to be processed is wound onto the reel. During processing, the wire core is gradually wrapped with insulation, and finally the take-up assembly 3 completes the winding. A heating module 6 and an injection mold 7 are bolted to the top center of the base 1. The heating module 6 is located on the right side of the injection mold 7 and is used to preheat the wire core, preparing it for the subsequent heat treatment of the insulation onto the outer surface of the wire core by the injection mold 7. An assembly head 8 is connected to the left end of the injection mold 7. The wire processed by the injection mold 7 is output from the machine head 8. The top of the base 1 is located on the right side of the heating module 6 and is connected to the support frame 11 by bolts. The upper side of the support frame 11 is rotatably connected to the rotating block 14. The inner side of the rotating block 14 is connected to the cleaning brush 15. The cleaning brush 15 has a hollow structure. This structure design can better adapt to the cleaning needs of the outer surface of the wire core. The hollow structure of the cleaning brush 15 is designed as a multi-layer nested structure. The inner layer directly contacts the wire core, and its inner diameter is closely matched with the outer diameter of the wire core, ensuring that the bristles can fully and tightly fit the surface of the wire core and improve the cleaning coverage. The middle layer is set with a buffer structure made of elastic rubber material, which can absorb the vibration caused by the bristles contacting the uneven parts of the wire core during the cleaning process, further protecting the wire core and reducing bristle wear. The outer layer adopts a reinforced design to enhance the overall strength of the brush body. This multi-layer nested structure not only ensures the cleaning effect, but also improves the durability of the cleaning brush 15 and its ability to protect the wire core. The top left side of the base 1 is equipped with a cooling component for cooling the wire after the insulation is wrapped. The support frame 11 is equipped with a rotating component.
[0022] like Figures 2-3 As shown, the rotating assembly includes a motor 12 and a gear 13. The motor 12 is bolted to the right side of the support frame 11. The gear 13 is welded to the output shaft of the motor 12. The gear 13 is also welded to the outside of the rotating block 14. The two gears 13 mesh with each other.
[0023] like Figures 1-2 As shown, the cooling assembly includes a water tank 9 and a water pump 10. The top of the base 1 is connected to the water tank 9 for storing coolant at the position on the left side of the injection mold 7. The water tank 9 has slots at the left and right ends for the processed wires to pass through. The water pump 10 is bolted to the front of the water tank 9. The water pump 10 can discharge the coolant in the water tank 9 to the outside through an external drain pipe.
[0024] Before processing the wire insulation, a series of preparatory work needs to be completed. The uninsulated wire core is mounted on the wire feeding assembly 2. One end of the wire core is passed sequentially through the cleaning brush 15, heating module 6, and injection mold 7, exiting from the machine head 8, then through the slot of the water tank 9, and finally wound onto the take-up assembly 3. Simultaneously, cooling water is added to the water tank 9, and the external component for conveying the insulation material is connected to the injection mold 7. After preparation, the wire feeding assembly 2, take-up assembly 3, heating module 6, and injection mold 7 are started. The take-up assembly 3 begins to work, pulling the wire to the left. During this process, the wire feeding assembly 2 simultaneously loosens the wire core, ensuring that the wire core is fed to the left at a uniform speed. Next, the motor 12 is started. The output shaft of motor 12 rotates, driving the rotating block 14 and cleaning brush 15 to rotate via the meshing of two gears 13. During rotation, the cleaning brush 15 cleans the outer surface of the wire core, removing any impurities or oil to ensure the accuracy of subsequent wire processing. The cleaned wire core enters the heating module 6, which preheats it to a suitable temperature for insulation heat treatment. The preheated wire core then enters the injection mold 7, where a heat treatment process tightly wraps the insulation around its outer surface. The insulated wire is then output from the machine head 8 and immediately enters the water tank 9. The coolant in the water tank 9 cools the wire, allowing the insulation to solidify quickly and ensuring the quality and performance of the wire. Finally, the cooled wire is wound onto the take-up assembly 3, completing the entire wire insulation wrapping process.
[0025] like Figure 3 As shown, it also includes a metal ring 16 and a magnetic ring 17. The metal ring 16 is connected to the right side of the rotating block 14. The magnetic ring 17 is assembled inside the metal ring 16 by magnetic adsorption. When the wire core is fed by the wire feeding assembly 2, it passes through the metal ring 16, the magnetic ring 17 and the cleaning brush 15 in sequence. While the rotating block 14 drives the cleaning brush 15 to clean the outer surface of the wire core, the rotating block 14 simultaneously drives the metal ring 16 and the magnetic ring 17 to rotate. Since the magnetic ring 17 is magnetic, it can effectively adsorb the small metal debris on the outer surface of the wire core, ensuring the cleanliness of the wire core. During subsequent maintenance, the magnetic ring 17 can be easily removed from the metal ring 16 to clean the adsorbed debris. The operation is convenient.
[0026] like Figure 1 , Figure 3 and Figure 4As shown, it also includes an air pump 18, a frame 19, and a filter 20. The air pump 18 is bolted to the left side of the support frame 11. The frame 19 for collecting debris is connected to the support frame 11 above the air pump 18. The pipe at the upper end of the air pump 18 is connected to and maintains communication with the frame 19. The filter 20 is welded to the inside of the frame 19 where it communicates with the pipe. The frame 19 is located below the left side of the cleaning brush 15. When the cleaning brush 15 rotates to clean the impurities on the outer surface of the wire core, the air pump 18 is started simultaneously. The air pump 18 draws air downwards into the frame 19 and then discharges it through the pipe. During this process, the debris scraped off by the cleaning brush 15 is drawn downwards into the frame 19 under the suction of the air pump 18, effectively preventing the debris from scattering randomly. The filter 20 prevents debris from entering the air pump 18. After the wire processing is completed, the air pump 18 is turned off, and the debris accumulated in the frame 19 can be cleaned to keep the working environment clean.
