Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulation layer curing technology, and in particular to a device for curing enameled wire insulation layer. Background Technology
[0002] Enameled wire, as a core member of the winding wire family, has a precise structure and rigorous process. It uses high-purity metal conductors such as copper, aluminum or alloys as the base material. After the internal stress is eliminated and the ductility is improved by the annealing process, special insulating varnishes such as polyester, polyurethane or polyimide are coated on the conductor surface in layers by precision coating equipment. Each layer of varnish film needs to be baked and cured at high temperature to form a dense insulating layer.
[0003] In the traditional curing process of enameled wire insulation, the commonly used hot air circulation heating method has low heat conduction efficiency, resulting in high energy consumption. At the same time, due to uneven airflow distribution, there is a significant temperature gradient inside the oven, which seriously affects the uniformity of insulation curing.
[0004] Therefore, it is necessary to design a device for curing the insulation layer of enameled wire to solve the above-mentioned technical problems. Utility Model Content
[0005] To overcome the aforementioned drawbacks, this utility model provides a device for curing the insulation layer of enameled wire.
[0006] A device for curing the insulation layer of enameled wire includes a base, a protective shell, a preheating pipe, a medium-heating pipe, a high-heating pipe, connecting rods, and pulleys. The protective shell is fixedly connected to the upper part of the base. The preheating pipe is fixedly connected to the right side of the inside of the protective shell. The medium-heating pipe is fixedly connected to the middle of the inside of the protective shell. The high-heating pipe is fixedly connected to the left side of the inside of the protective shell. The preheating pipe, the medium-heating pipe, and the high-heating pipe are interconnected, and the volume decreases as they move to the left. Multiple connecting rods are fixedly connected inside the preheating pipe, the medium-heating pipe, and the high-heating pipe. Each connecting rod is rotatably connected to a pulley.
[0007] To further explain, it also includes a cooling box, a fan, a filter screen, and activated carbon. The cooling box is fixedly connected to the left side of the protective shell and is connected to a high-heat pipe. The fan is fixedly connected to the lower part of the cooling box, and the filter screen is fixedly connected to the bottom of the cooling box. The filter screen is located below the fan, and activated carbon is fixedly connected to the upper part of the cooling box.
[0008] To further explain, it also includes a controller, which is fixedly connected to the front of the cooling box. The fan, preheating pipe, medium heat pipe and high heat pipe are all electrically connected to the controller.
[0009] To further explain, it also includes a nut, a threaded rod, a support plate, and a guide rod. A nut is fixedly connected to the front side of the base, and a threaded rod is threadedly connected to the nut. A support plate is fixedly connected to the bottom of the threaded rod. The base restricts the rotation of the support plate. A guide rod is slidably connected to the rear side of the base, and the guide rod is in contact with the base.
[0010] To further explain, it also includes a handle, which is fixedly connected to the upper part of the protective shell.
[0011] To further explain, it also includes a partition, with a partition fixedly connected to the lower part of the handle, and the partition is made of heat-insulating material.
[0012] The beneficial effects of this utility model are as follows: 1. This utility model adopts a three-section heating system consisting of a preheating pipe, a medium-heating pipe and a high-heating pipe arranged sequentially from right to left. The volume of each section decreases and the temperature increases. Combined with the connecting rod and pulley structure distributed in a ring array, the enameled wire maintains stable tension and is gradually heated and cured during the journey. This design effectively improves the heat conduction efficiency and avoids the temperature gradient problem in the traditional hot air circulation method.
[0013] 2. This utility model has a cooling box at the end of the device, which integrates a fan, a filter and an activated carbon module for rapid cooling of the cured enameled wire. At the same time, it adsorbs the volatile organic compounds generated during the curing process and purifies the exhaust air. This structure not only improves the environmental friendliness of the production process, but also effectively prevents surface defects of the finished product caused by excessive temperature difference or environmental impurities.
[0014] 3. This utility model uses a height adjustment mechanism consisting of a nut, threaded rod, support plate and guide rod on the front side of the base to allow the device to be flexibly adjusted in terms of installation height according to the needs of different production lines. The top of the protective shell is equipped with a handle and a heat insulation plate to facilitate handling and prevent heat loss. Attached Figure Description

Detailed Implementation
[0020] Example: A device for curing the insulation layer of enameled wire, such as Figure 1 , Figure 3 and Figure 4 As shown, the device includes a base 1, a protective shell 2, a preheating pipe 3, a medium-heating pipe 4, a high-heating pipe 5, connecting rods 6, pulleys 7, and a controller 12. The protective shell 2 is bolted to the upper part of the base 1. The preheating pipe 3 is bolted to the right side of the inside of the protective shell 2. The medium-heating pipe 4 is bolted to the middle of the inside of the protective shell 2. The high-heating pipe 5 is bolted to the left side of the inside of the protective shell 2. The preheating pipe 3, the medium-heating pipe 4, and the high-heating pipe 5 are interconnected, and the volume decreases as they move to the left. Multiple connecting rods 6 arranged in a ring array are fixedly connected inside the preheating pipe 3, the medium-heating pipe 4, and the high-heating pipe 5. Each connecting rod 6 is rotatably connected to a pulley 7. The controller 12 is bolted to the front of the cooling box 8. The preheating pipe 3, the medium-heating pipe 4, and the high-heating pipe 5 are all electrically connected to the controller 12.
[0021] When this device is needed, the temperature of the preheating pipe 3, the medium-heating pipe 4, and the high-heating pipe 5 is adjusted by the controller 12. The enameled wire enters from the right side of the preheating pipe 3 and passes through the medium-heating pipe 4 and the high-heating pipe 5 in sequence. The volume of the three pipe sections decreases from right to left, and the heat also increases from right to left. The device is equipped with connecting rods 6 and pulleys 7 arranged in a ring array inside, which allows the enameled wire to move on the pulleys 7, ensuring that it moves stably in the center of the pipe, reducing friction and helping to heat evenly. The preheating section is mainly used to remove moisture and volatile components from the surface of the paint layer. The medium-heating section further increases the temperature and promotes the initial cross-linking of the paint film. The high-heating section provides a high-temperature environment so that the insulation layer can complete the final curing reaction and form a dense and strongly adhesive insulation layer.
[0022] like Figure 1 and Figure 3 As shown, it also includes a cooling box 8, a fan 9, a filter screen 10, and activated carbon 11. The cooling box 8 is bolted to the left side of the protective shell 2. The cooling box 8 is connected to the high-heat pipe 5. The fan 9 is bolted to the middle of the lower part of the cooling box 8. The fan 9 is electrically connected to the controller. The filter screen 10 is fixedly connected to the bottom of the cooling box 8. The filter screen 10 is located below the fan 9. The activated carbon 11 is fixedly connected to the middle of the upper part of the cooling box 8.
[0023] After curing, the fan 9 is turned on by the controller 12, and the enameled wire enters the cooling box 8 connected on the left. The fan 9 draws in outside air, removes impurities through the filter screen 10, and blows it onto the enameled wire. Activated carbon 11 is used to adsorb the volatile organic compounds generated during the curing process, achieving environmentally friendly cooling and ensuring that the finished product quality is stable and meets emission standards.
[0024] like Figure 1 and Figure 4 As shown, it also includes a nut 13, a threaded rod 14, a support plate 15, a guide rod 16, a handle 17, and a partition 18. The nut 13 is fixedly connected to the upper front side of the base 1. The threaded rod 14 is threadedly connected to the nut 13. The support plate 15 is fixedly connected to the bottom of the threaded rod 14. The base 1 restricts the rotation of the support plate 15. The guide rod 16 is slidably connected to the middle of the rear side of the base 1. The guide rod 16 contacts the base 1. The handle 17 is fixedly connected to the upper part of the protective shell 2. The partition 18 is fixedly connected to the lower part of the handle 17. The partition 18 is made of heat-insulating material.
[0025] The front side of the base 1 is provided with a nut 13 and a threaded rod 14 for adjusting the height of the device. By rotating the threaded rod 14 and cooperating with the guide rod 16, the support plate 15 can be raised or lowered to raise the height of the device, thereby realizing the height adjustment and stable support of the whole machine. The upper part of the protective shell 2 is provided with a handle 17 and a heat insulation plate 18 for easy handling and to prevent heat leakage.
