Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic wire drying technology, specifically an electromagnetic wire drying oven. Background Technology
[0002] Electromagnetic wire, also known as winding wire, is an insulated wire used to manufacture coils or windings in electrical products. Electromagnetic wire is generally divided into enameled wire, wrapped wire, enameled and wrapped wire, and inorganic insulated wire. Electromagnetic wire is mainly made of copper wire. In the production process of electromagnetic wire, it is necessary to go through processes such as material preparation, wire drawing, water washing, annealing, impregnation, drying, and winding to finally produce the required electromagnetic wire. When annealing the copper wire, an annealing furnace is usually used for heating.
[0003] The specific design and structure of an electromagnetic wire drying oven may vary depending on the manufacturer and application requirements, but generally they include the following key components: oven frame, heating element, and traction device. The oven frame is made of welded metal profiles, providing support for the equipment and ensuring structural stability. Common types of heating elements include resistance heating, where current passes through resistance wire to generate heat. This type is simple in structure, low in cost, and suitable for general temperature ranges. The traction device controls the electromagnetic wire to pass through the drying oven at a constant speed and tension, preventing the wire from tangling, stretching, deforming, or deviating.
[0004] Traditional electromagnetic wire drying ovens often experience slippage, deformation, or surface damage when processing electromagnetic wires of different diameters due to the fixed clamping force. If the exhaust gas generated during the electromagnetic wire drying process is discharged directly without effective treatment, it will cause environmental pollution. The filter replacement of traditional purification equipment is complicated and the maintenance cost is high. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes an electromagnetic wire drying oven.
[0006] The technical solution adopted by this utility model to solve its technical problem is an electromagnetic wire drying oven, including a drying oven body. A set of transmission rods is respectively arranged at both ends of the drying oven body, and five sets of transmission rollers are respectively arranged on the two transmission rods. Two sets of motor supports are arranged on the side of the drying oven body, and a transmission motor is arranged on each of the two sets of motor supports. The output ends of the two transmission motors are respectively fixedly connected to the top of a transmission rod. A set of adjustment grooves is symmetrically opened at both ends of the drying oven body. A mounting plate is slidably arranged in each of the two sets of adjustment grooves. An adjustment spring is fixedly arranged at the top of each of the two sets of mounting plates. The adjustment spring is arranged in the adjustment groove, and the top of the adjustment spring is fixedly connected to the top of the adjustment groove. A driven rod is rotatably arranged between the two sets of mounting plates, and five sets of driven rollers are respectively arranged on the two sets of driven rods.
[0007] Preferably, the drying oven body is provided with a drying trough, and a drying box is provided below the drying trough. A drying motor is fixedly installed in the drying box, and a drying fan is provided on the output end of the drying motor. A heating tube is provided above the drying fan. The bottom-mounted hot air supply method allows the hot air to fully contact the electromagnetic wire. By utilizing the principle of thermal radiation, the electromagnetic wire can be dried in an all-round and efficient manner, effectively shortening the drying time and improving production efficiency.
[0008] Preferably, the main body of the drying oven is provided with a mounting frame on the side, and a waste gas treatment box is provided on the mounting frame. The waste gas treatment box is provided with multiple sets of slide rails, and an activated carbon plate is slidably installed in each of the multiple sets of slide rails. Each activated carbon plate is provided with a mounting handle, and a treatment fan is provided on the side of the waste gas treatment box.
[0009] Preferably, a gas collecting hood and a drying hood are symmetrically arranged at both ends of the main body of the drying furnace, and the gas collecting hood, the waste gas treatment box, the treatment fan and the drying hood are connected in sequence by a drying pipe.
[0010] Preferably, an installation rod is fixedly installed inside the drying hood, a rotating seat is rotatably installed at the top of the installation rod, and five sets of rotating blades are rotatably installed at the bottom of the installation rod. The five sets of transmission rollers, the five sets of driven rollers and the five sets of rotating blades are arranged in a one-to-one correspondence.
[0011] Preferably, the drive motor, drying motor, and processing fan are all connected to an external controller. The controller is used to start and stop the drive motor, drying motor, and processing fan, thereby realizing intelligent and automated control of equipment operation.
[0012] The advantages of this utility model are: the adjusting groove, mounting plate, adjusting spring, driven rod and driven roller symmetrically arranged at both ends of the drying oven body form an adaptive adjustment system, which can automatically adjust the clamping force according to the change of the diameter of the electromagnetic wire. This not only ensures the stable transmission of electromagnetic wires of different specifications, but also effectively avoids damage to the surface of the electromagnetic wire caused by excessive clamping, thus improving the versatility and applicability of the equipment.
[0013] The exhaust gas treatment box on the mounting frame is equipped with slide rails, activated carbon plates, and a treatment fan, forming a complete exhaust gas purification system. The slide rail design facilitates the installation, disassembly, and replacement of the activated carbon plates. When the activated carbon plates are saturated, operators can easily pull out the old plates and replace them with new ones using the installation handles, ensuring that the exhaust gas treatment system maintains a high level of purification capacity while reducing the difficulty and cost of equipment maintenance.
[0014] The gas collection hoods and drying hoods at both ends of the main body of the drying oven are connected to the drying pipes, which organically combine the drying area and the waste gas treatment system to form a hot air circulation loop. This enables the reuse of heat, significantly improves energy efficiency, and reduces energy consumption costs in the production process. The mounting rods, rotating seats, and rotating blades inside the drying hood can rotate under the drive of airflow when hot air passes through, dispersing the hot air evenly onto the surface of the electromagnetic wire, further improving the uniformity of drying.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figure 1-5 As shown, an electromagnetic wire drying oven includes a drying oven body 1. A set of transmission rods 2 are respectively provided at both ends of the drying oven body 1. Five sets of transmission rollers 3 are respectively provided on the two transmission rods 2. Two sets of motor brackets 4 are provided on the side of the drying oven body 1. A transmission motor 5 is provided on each of the two sets of motor brackets 4. The output ends of the two transmission motors 5 are respectively fixedly connected to the top of a transmission rod 2.
[0024] The drying oven body 1 has a set of adjustment grooves 6 symmetrically opened at both ends. A mounting plate 7 is slidably arranged in each of the two sets of adjustment grooves 6. An adjustment spring 8 is fixedly arranged at the top of each of the two sets of mounting plates 7. The adjustment spring 8 is arranged in the adjustment groove 6 and its top is fixedly connected to the top of the adjustment groove 6. A driven rod 9 is rotatably arranged between the two sets of mounting plates 7. Five sets of driven rollers 10 are arranged on each of the two sets of driven rods 9.
[0025] During operation, in order to transmit the electromagnetic wire, the controller controls the drive motor 5 to output power to drive the drive rod 2 to rotate, which in turn drives the drive roller 3 to rotate, providing active traction power for the electromagnetic wire. The tension of the spring 8 is adjusted to keep the driven roller 10 in close contact with the electromagnetic wire. When the diameter of the electromagnetic wire changes, the mounting plate 7 can slide in the adjustment groove 6, and the driven roller 10 adjusts its position accordingly to ensure a stable clamping force with the drive roller 3, so as to realize the smooth transmission of electromagnetic wires of different specifications.
[0026] The drying oven body 1 is provided with a drying trough 21, and a drying box 17 is provided below the drying trough 21. A drying motor 18 is fixedly installed in the drying box 17. A drying fan 19 is provided on the output end of the drying motor 18. A heating tube 20 is provided above the drying fan 19.
[0027] During operation, in order to dry the electromagnetic wire, the drying motor 18 drives the drying fan 19 to rotate, and the heat generated by the heating tube 20 is transported upward to the drying tank 21 in the main body of the drying oven 1. A high-temperature environment is formed in the drying tank 21. When the electromagnetic wire passes through the drying tank 21, the heat is transferred to the surface of the electromagnetic wire by means of thermal radiation, causing the surface moisture to evaporate and completing the drying process.
[0028] The main body 1 of the drying oven is provided with a mounting frame 11 on its side. A waste gas treatment box 13 is provided on the mounting frame 11. Multiple sets of slide rails 23 are provided inside the waste gas treatment box 13. An activated carbon plate 24 is slidably installed in each of the multiple sets of slide rails 23. Each activated carbon plate 24 is provided with a mounting handle 25. A treatment fan 14 is provided on the side of the waste gas treatment box 13. A gas collecting hood 12 and a drying hood 15 are symmetrically arranged at both ends of the main body 1 of the drying oven. The gas collecting hood 12, the waste gas treatment box 13, the treatment fan 14 and the drying hood 15 are connected in sequence by a drying pipe 16.
[0029] An installation rod 26 is fixedly installed inside the drying hood 15. A rotating seat 27 is rotatably installed at the top of the installation rod 26, and five sets of rotating blades 28 are rotatably installed at the bottom of the installation rod 26. The five sets of drive rollers 3, the five sets of driven rollers 10 and the five sets of rotating blades 28 are arranged in a one-to-one correspondence. The drive motor 5, the drying motor 18 and the processing fan 14 are all connected to an external controller. The controller is used to control the start and stop of the drive motor 5, the drying motor 18 and the processing fan 14.
[0030] During operation, in order to treat and recycle the waste gas, the processing fan 14 generates negative pressure, forming suction at the gas collection hood 12, which draws the waste gas containing water vapor and volatile substances generated during the drying process into the drying pipe 16. The waste gas enters the waste gas treatment box 13, where the activated carbon plate 24 adsorbs and purifies the volatile organic compounds and particulate impurities in the waste gas. The purified hot air is then transported through the drying pipe 16 to the drying hood 15 and re-enters the drying area to participate in the drying process, thus realizing the recycling of hot air. At the same time, the rotating blades 28 inside the drying hood 15 are driven to rotate by the airflow, which evenly disperses the hot air on the surface of the electromagnetic wire, improving the drying uniformity and efficiency.
[0031] Working principle: In order to transmit the electromagnetic wire, the controller controls the transmission motor 5 to output power to drive the transmission rod 2 to rotate, which in turn drives the transmission roller 3 to rotate, providing active traction power for the electromagnetic wire. The tension of the spring 8 is adjusted to keep the driven roller 10 in close contact with the electromagnetic wire. When the diameter of the electromagnetic wire changes, the mounting plate 7 can slide in the adjustment groove 6, and the driven roller 10 adjusts its position accordingly to ensure a stable clamping force with the transmission roller 3, so as to realize the smooth transmission of electromagnetic wires of different specifications.
[0032] In order to dry the electromagnetic wire, the drying motor 18 drives the drying fan 19 to rotate, and the heat generated by the heating tube 20 is transported upward to the drying tank 21 in the main body of the drying oven 1. A high temperature environment is formed in the drying tank 21. When the electromagnetic wire passes through the drying tank 21, the heat is transferred to the surface of the electromagnetic wire by means of thermal radiation, causing the surface moisture to evaporate and completing the drying process.
[0033] To recycle the treated waste gas, the processing fan 14 generates negative pressure, creating suction at the gas collection hood 12. This suction draws the waste gas containing water vapor and volatile substances generated during the drying process into the drying pipe 16. The waste gas then enters the waste gas treatment box 13, where the activated carbon plate 24 adsorbs and purifies the volatile organic compounds and particulate impurities in the waste gas. The purified hot air is then transported through the drying pipe 16 to the drying hood 15, where it re-enters the drying area to participate in the drying process, thus achieving hot air recycling. Simultaneously, the rotating blades 28 inside the drying hood 15 are driven by the airflow to rotate, evenly dispersing the hot air onto the surface of the electromagnetic wire, improving drying uniformity and efficiency.
