Description

Technical Field

[0001] This utility model relates to the technical field of drying devices for enameled wire production, and in particular to a drying device for enameled wire production. Background Technology

[0002] After enameling, enameled wire needs to be dried to make the surface coating firm. In the existing technology, the conventional drying device for enameled wire production is a drying box with open ends + a single-sided hot air direct blowing device + a simple support roller structure inside the box. Its working method is that hot air is introduced from one side of the drying box, and the hot air passes through the surface of the enameled wire and is directly discharged from the open opening at the other end of the box. There is no hot air circulation structure or opening adjustment structure. Because the hot air is easy to escape in large quantities from the open opening and is discharged after only one use, the heat energy is not fully utilized, resulting in a high heat energy loss rate and high drying cost. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problems mentioned above, a drying device for enameled wire production is provided. Through structural improvements, the heat loss is reduced from the source and the heat energy is recycled, thereby reducing heat loss in principle and solving the problem of high heat loss rate of existing drying devices.

[0004] The present invention solves its technical problem by adopting the following technical solution: a drying device for enameled wire production includes a drying box that runs through the left and right sides. Two spaced-apart brackets are fixedly provided on the lower end face of the drying box to support it. Opening adjustment devices are provided at both ends of the drying box to adjust the opening, thereby structurally reducing the amount of hot air escaping from the opening of the drying box. In addition, a circulating hot air blowing device is provided on the drying box to provide continuous circulating hot air to the inner cavity of the drying box, thereby realizing the recycling of heat energy, improving the heat energy utilization rate, and effectively reducing energy consumption.

[0005] Preferably, insert plates are symmetrically inserted at both ends of the drying oven, and a limiting plate is fixed at the end of the insert plate. On the other side of the insert plate, there are spaced wire holes for enameled wires to enter. When the enameled wire passes through the wire hole, only the wire passage gap that the enameled wire is adapted to is retained, and the remaining opening area is closed by the insert plate to minimize the loss of hot air.

[0006] Preferably, the outer wall of the insert plate is provided with magnetic material, and the insert plate can be magnetically attracted to the drying box to lock its position. The position of the insert plate can be adjusted according to different diameter enameled wires to make the wire hole fit the enameled wire and ensure the opening sealing effect of products of different specifications.

[0007] Preferably, a hot air circulation pipe connecting the upper and lower end faces is provided in the middle of the drying chamber, and a fan is provided in the middle of the hot air circulation pipe for blowing air into the drying chamber.

[0008] Preferably, an electric heating plate is fixed on the hot drying circulation pipe and connected in series with the hot drying circulation pipe. After the electric heating plate is energized, it heats the air, causing the fan to blow hot air onto the surface of the enameled wire to dry it. After the hot air is dried on the surface of the enameled wire, it is recycled back to the electric heating plate through the hot drying circulation pipe for reheating and then blown back into the drying chamber, forming a closed hot air circulation and realizing the recycling of heat energy.

[0009] Preferably, a wire-supporting roller is provided at intervals inside the drying chamber. The wire-supporting roller is used to support the enameled wire passing through the drying chamber, ensuring the smooth transmission of the enameled wire inside the drying chamber, so that the enameled wire can fully contact the hot air and improve the drying effect.

[0010] The advantages and positive effects of this utility model are as follows: By sealing off the excess openings of the drying box through the insert-type opening adjustment device, only the gap for the enameled wire to pass through is retained, which directly reduces the loss of hot air from the openings from the structure. At the same time, the circulating hot air blowing device formed by the hot drying circulation pipe, fan, and electric heating plate realizes the closed circulation flow of hot air and the recycling of heat energy. From the two core dimensions of "reducing hot air loss" and "improving heat energy utilization", the heat energy loss is significantly reduced in principle, solving the technical defects of the prior art. Moreover, the insert plate can be magnetically locked and adapted to enameled wires of different diameters, and the wire-carrying rollers ensure the smooth transmission of enameled wires. The overall structure of the device is simple and easy to operate, and it is suitable for the needs of large-scale production of enameled wires. Attached Figure Description

[0015] As shown in Figures 1-2, the drying device for enameled wire production of this utility model includes a drying box 12 that runs through the left and right sides. Two spaced supports 14 are fixedly provided on the lower end face of the drying box 12 to support the drying box 12.

A limiting plate 11 is fixed at the end of the insert plate 10, and a spaced wire hole 15 is provided on the other side of the insert plate 10 for the enameled wire to enter. When the enameled wire passes through the wire hole 15, only the wire passage gap that the enameled wire is adapted to is retained, and the remaining opening area is closed by the insert plate 10 to reduce the escape of hot air.

[0017] Preferably, the outer wall of the insert plate 10 is provided with magnetic material, and the insert plate 10 can be magnetically attracted to the drying box 12 to lock its position. The position of the insert plate 10 can be adjusted according to the enameled wire of different diameters to adapt to the drying requirements of products of different specifications.

[0019] Preferably, an electric heating plate 17 is also fixed on the hot drying circulation pipe 13 and connected in series with the hot drying circulation pipe 13. After the electric heating plate 17 is energized, it heats the air so that the fan 18 blows hot air onto the surface of the enameled wire to dry it. After the hot air is dried on the surface of the enameled wire, it is recycled back to the electric heating plate 17 through the hot drying circulation pipe 13 for heating, and then blown back into the drying box 12 to form a closed hot air circulation, thereby realizing the recycling of heat energy.
