Description

Technical Field

[0001] This utility model relates to the technical field of enameled wire production equipment, specifically a horizontal enameled wire baking device. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer needs is not easy, as it is affected by factors such as raw material quality, process parameters, production equipment, and the environment.

[0003] After the enameled wire is coated with enamel, it needs to be dried at high temperature in a baking equipment to solidify the enamel film. Existing enameled wire baking equipment generally uses heated air to blow the enameled wire into the baking equipment. However, the hot air will be discharged from the baking equipment into the workshop through the enameled wire outlet. This not only causes heat loss inside the baking equipment, requiring the air inside the equipment to be reheated, which increases energy consumption, but also causes the workshop temperature to rise. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a horizontal enameled wire baking device.

The air inlet end of the heat exchange tube is connected to the baking oven through a first conduit, and the air outlet end of the heat exchange tube is connected to the top of the air inlet pipe through a second conduit.

[0009] To improve the baking efficiency of enameled wire, the improvement of this utility model is that the included angle between the air outlet pipe and the diversion pipe is 45 degrees.

[0024] 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 protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model discloses a horizontal enameled wire baking device, including a processing table 1, a baking oven 2 at the upper end of the processing table 1, a hot air blower 5 at the upper end of the baking oven 2, an air inlet pipe 6 at the air inlet end of the hot air blower 5, a transfer pipe 7 inserted into the baking oven 2 at the air outlet end of the hot air blower 5, an annular transfer box 8 at the bottom end of the transfer pipe 7, an annular diversion box 9 on one side of the annular transfer box 8, a plurality of diversion pipes 13 on the annular diversion box 9, and a plurality of air outlet pipes 14 inclinedly arranged on the diversion pipes 13.

[0026] The upper end of the hot air blower 5 is provided with a heat exchange jacket 15 through which the air inlet pipe 6 passes. A spiral heat exchange tube is coiled inside the heat exchange jacket 15. The air inlet end of the heat exchange tube is connected to the baking oven 2 through a first conduit 16, and the air outlet end of the heat exchange tube is connected to the top of the air inlet pipe 6 through a second conduit 17.

[0027] The motor 11 is a servo motor.

[0028] The baking oven 2 has two symmetrically arranged side plates 18 at both ends, and the side plates 18 are provided with sealing rings 19 through which enameled wires pass.

[0029] The enameled wire enters the baking oven 2 through the sealing ring 19 on one side plate 18 for baking. During this process, the conveyor wheels on the support frame ensure stable transport of the enameled wire. After the hot air blower 5 is started, outside air enters the hot air blower 5 through the air inlet pipe 6. The hot air blower 5 heats the air and then delivers the hot air to the annular transfer box 8 through the adapter pipe 7 at the air outlet.

[0030] The sealing rings 19 on the side plates 18 at both ends of the baking oven 2 effectively reduce the heat loss inside the baking oven 2, further reducing energy consumption, and also preventing the problem of hot air being discharged into the workshop and causing the workshop temperature to rise.

[0031] The included angle between the air outlet duct 14 and the diversion duct 13 is 45 degrees.

[0032] Hot air from the annular junction box 8 enters the connected annular distribution box 9. Multiple distribution pipes 13 are distributed on the annular distribution box 9, and multiple outlet pipes 14 are inclinedly arranged on the distribution pipes 13, with an external angle of 45 degrees between the outlet pipes 14 and the distribution pipes 13. This design allows hot air to be blown towards the enameled wire at a specific angle, increasing the contact area and contact effect between the hot air and the enameled wire, thus helping to improve baking efficiency.

[0033] The annular diverter box 9 is rotatably connected to the annular adapter box 8. The annular diverter box 9 is provided with a toothed ring 10 on its periphery. The annular adapter box 8 is provided with a motor 11 below it. The output end of the motor 11 is provided with a gear 12 that meshes with the toothed ring 10. The annular adapter box 8 is provided with a docking groove 22 on the side near the annular diverter box 9. The inner ring of the docking groove 22 is provided with a sealed bearing. The annular diverter box 9 is provided with a docking ring 21 that is inserted into the inner ring of the sealed bearing on the side near the annular adapter box 8.

[0034] To ensure more even distribution of hot air to the enameled wire, motor 11 is activated. Motor 11 is a servo motor; its output gear 12 meshes with the gear ring 10 on the periphery of the annular distribution box 9, causing the annular distribution box 9 to rotate relative to the annular transfer box 8. The annular transfer box 8 has a docking groove 22 on the side closest to the annular distribution box 9. The sealed bearing inside the docking groove 22 engages with the docking ring 21 of the annular distribution box 9, ensuring smooth rotation and a tight seal. As the annular distribution box 9 rotates, each air outlet duct 14 can provide all-around hot air baking to the enameled wire, avoiding any blind spots in the baking process.

[0035] During the baking process, the air carrying a certain amount of heat inside the baking oven 2 enters the heat exchange tubes coiled inside the heat exchange jacket 15 through the first conduit 16. Meanwhile, the outside air entering the hot air blower 5 passes through the heat exchange jacket 15, which is pierced by the air inlet pipe 6. At this time, the high-temperature exhaust gas from the baking oven 2 enters the heat exchange tubes through the first conduit 16, and exchanges heat with the fresh air in the air inlet pipe 6 within the heat exchange jacket 15, preheating the air in the air inlet pipe 6. The preheated air then enters the hot air blower 5, reducing the energy consumption of the hot air blower 5 in heating the air to the required temperature. After heat exchange, the air in the heat exchange tubes returns to the top of the air inlet pipe 6 through the second conduit 17.

[0036] The oven 2 is equipped with an observation panel 20 at the front end.

[0037] Operators can observe the processing of the enameled wire inside the baking oven 2 in real time through the observation panel 20 at the front of the oven 2. After baking, the enameled wire exits through the sealing ring 19 on the other side plate 18 of the baking oven 2. The sealing ring 19 effectively reduces heat loss inside the baking oven 2.

[0038] The observation panel 20 at the front of the baking oven 2 allows operators to observe the baking status of the enameled wire in real time, identify problems in a timely manner and make adjustments, thereby improving the controllability of the production process.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
