Description

Technical Field

[0001] This application relates to the technical field of enameling machines, and more particularly, to a high-speed flat wire enameling machine. Background Art

[0002] An enameling machine is the main equipment for producing enameled wire. The wire feeding device uniformly feeds out the wire to be processed. The annealing device is used to anneal the wire to eliminate the internal stress of the wire, improve its softness and conductivity. The painting device is used to uniformly coat the insulating paint on the surface of the wire. Then the wire passes through the drying oven, and the insulating paint coated on the surface of the wire is cured by heating to form a firm insulating layer. Then it passes through the cooling device to cool the enameled wire after being cured in the drying oven. Finally, the produced enameled wire is neatly wound up.

[0003] In this regard, Chinese Patent Application No. CN202222283485.2 discloses an enameling machine drying device. This solution can mainly make the driving of the gear drive the ring gear to rotate through the mutual cooperation of the gear and the ring gear, and then drive the drying pipe inside the ring gear to rotate, further ensuring that the hot air inside the drying pipe evenly blows on the outer wall of the enameled wire, ensuring the uniform curing of the enameled wire, and at the same time avoiding the risk of uneven curing and deformation of the surface polyester paint caused by the enameled wire being heated in a single direction.

[0004] However, in the process of the applicant of this utility model implementing the technical solution in the embodiment of this application, it is found that the above technology has at least the following technical problems:

[0005] 1. The rotation mechanism of the drying pipe is complex, and the sealing with the air inlet also needs to be ensured. If the flat wire passes through at high speed, the rotation speed of the drying pipe also needs to be increased accordingly, so the cost is relatively high;

[0006] 2. The paint film on the surface of the wire will flow downward under the action of gravity, resulting in uneven paint film.

[0007] 3. For the drying of flat wires, there is air leakage at both ends of the drying pipe, which will cause loss of hot air and high energy consumption. Summary of the Utility Model

[0008] In order to make up for the above deficiencies, this application provides a high-speed flat wire enameling machine, aiming to improve the problems mentioned in the above background art.

[0009] The embodiment of this application provides a high-speed flat wire enameling machine, including an oven and a flat wire. The flat wire enters from one end of the oven, twists 360 degrees and then exits from the other end of the oven. Guide members are respectively arranged at both ends of the oven, and a blowing member is arranged inside the oven.

[0010] In a specific implementation, the oven includes a box body and a box cover, and the box cover is inserted into the box body.

[0011] In a specific embodiment, a gasket is provided between the box body and the box cover.

[0012] In the above implementation process, after the flat wire is threaded, the box cover is covered, and the gasket is used to improve the sealing performance. The box cover is inserted in a way that is convenient for operation.

[0013] In a specific embodiment, an electric heating tube is provided inside the box body.

[0014] In the above implementation process, the electric heating tube is strip-shaped and arranged along the flat wire. Since the flat wire is twisted 360 degrees, it can be evenly heated.

[0015] In a specific embodiment, the guiding member includes two upper and lower pressure rollers, and the two pressure rollers are respectively rotatably connected to the box body and the box cover.

[0016] In the above implementation process, the two upper and lower pressure rollers press the flat wire to ensure the accurate attitude of the flat wire entering and exiting. In this embodiment, the distance between the two pressure rollers can be adjusted by using gaskets of different specifications, so as to adapt to flat wires of different thicknesses. The upper pressure roller uses its own gravity to maintain the pressing on the flat wire.

[0017] In a specific embodiment, the guiding member further includes a bidirectional lead screw and sliders. The lead screw is rotatably connected to the box body, and each end of the lead screw is threadedly connected to a slider. A vertical retaining roller is rotatably connected to the slider.

[0018] In a specific embodiment, the guiding member further includes a motor A. The motor A is installed outside the box body, and the output end of the motor A is fixedly connected to the lead screw.

[0019] In the above implementation process, by driving the forward and reverse rotation of the lead screw by the motor A, the two sliders can be controlled to close or separate, so as to control the left and right vertical retaining rollers to bind the flat wire to the central position from both sides, thereby binding the flat wire to a fixed position in the oven for accurate heating. In this embodiment, a guide rail is also provided to guide the sliding of the slider.

[0020] In a specific embodiment, the air blowing member includes a fan and a motor B. There are two fans, which are respectively rotatably connected to both ends of the box body. The motor B is installed outside the box body, and the two output ends of the motor B are respectively connected to the two fan shafts.

[0021] In the above implementation process, motor B drives the rotation of two fans synchronously through the transmission of two pairs of bevel gears. The two fans are located at both ends of the box body, and the air flow directions are opposite, so that the air flow can circulate in the oven, ensuring uniform heat in the oven and facilitating uniform heating of the surface of the flat wire.

[0022] Compared with the prior art, the beneficial effects of the present application are as follows: The guiding member is used to guide the flat wire to reduce the air leakage at both ends of the oven, reduce energy consumption, and also use the guiding member to make the flat wire twist 360 degrees when passing through the oven for uniform heating. Compared with the rotation mode of the drying tube, the structural cost is lower, and it can also meet the requirements of high-speed wire passing. Moreover, when the flat wire twists, the situation of the paint film flowing in one direction can be reduced, which is beneficial to the uniformity of the paint film.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

[0030] Please refer to Figures 1 - 4, this application provides a high-speed flat wire enameling machine, which includes an oven 10 and a flat wire 20. The flat wire 20 enters from one end of the oven 10, twists 360 degrees and then exits from the other end of the oven 10. Guide members 30 are respectively arranged at both ends of the oven 10, and a blower member 40 is arranged inside the oven 10. Among them, the guide member 30 is used to guide the flat wire 20 to reduce air leakage at both ends of the oven 10, reduce energy consumption, and also use the guide member 30 to make the flat wire 20 twist 360 degrees when passing through the oven 10 so as to be evenly heated. Compared with the rotation mode of the drying tube, the structural cost is lower, and it can also meet the requirements of high-speed wire passing. Moreover, when the flat wire 20 twists, the situation where the paint film flows in one direction can be reduced, which is beneficial to the uniformity of the paint film.

[0031] Please refer to Figures 1 - 4 , the oven 10 includes a box body 11 and a box cover 12, and the box cover 12 is inserted into the box body 11. A sealing gasket 13 is arranged between the box body 11 and the box cover 12. After the flat wire 20 is threaded, the box cover 12 is covered, and the sealing gasket 13 is used to improve the sealing performance. The box cover 12 is inserted in a way that is convenient for operation.

[0032] Please refer to Figures 1 - 4 , electric heating tubes 14 are arranged inside the box body 11. The electric heating tubes 14 are strip-shaped and arranged along the flat wire 20. Since the flat wire 20 twists 360 degrees, it can be evenly heated by itself.

[0033] Please refer to Figures 1 - 4 , the guide member 30 includes two upper and lower pressure rollers 31, and the two pressure rollers 31 are respectively rotatably connected to the box body 11 and the box cover 12. The two upper and lower pressure rollers 31 press the flat wire 20 to ensure the accurate attitude of the flat wire 20 when entering and exiting. In this embodiment, the distance between the two pressure rollers 31 can be adjusted by using sealing gaskets 13 of different specifications, so as to adapt to flat wires 20 of different thicknesses. The upper pressure roller 31 uses its own gravity to maintain the pressing on the flat wire 20.

[0034] Please refer to Figures 1 - 4 , the guide member 30 further includes a bidirectional lead screw 32 and a slider 33. The lead screw 32 is rotatably connected to the box body 11. A slider 33 is respectively threadedly connected to both ends of the lead screw 32, and a vertical retaining roller 34 is rotatably connected to the slider 33. The guide member 30 further includes a motor A35. The motor A35 is installed outside the box body 11, and the output end of the motor A35 is fixedly connected to the lead screw 32. By driving the forward and reverse rotation of the lead screw 32 by the motor A35, the two sliders 33 can be controlled to close or separate, so as to control the left and right vertical retaining rollers 34 to bind the flat wire 20 in the center position from both sides, thereby binding the flat wire 20 in a fixed position inside the oven 10 for accurate heating. In this embodiment, a guide rail 36 is also provided to guide the sliding of the slider 33.

[0035] Please refer to Figures 1 - 4, the air blowing member 40 includes a fan 41 and a motor B42. There are two fans 41, which are respectively rotatably connected to both ends of the box body 11. The motor B42 is installed outside the box body 11, and the two output ends of the motor B42 are respectively shaft-connected to the two fans 41. The motor B42 synchronously drives the two fans 41 to rotate through the transmission of two pairs of bevel gears. The two fans 41 are located at both ends of the box body 11 and have opposite wind directions, so that the air flow can circulate in the oven 10, ensuring uniform heat in the oven 10, which is beneficial to the uniform heating of the surface of the flat wire 20.

[0036] The working principle of this high-speed enamelled flat wire machine is as follows: The flat wire 20 is twisted 360 degrees. The two ends of the flat wire 20 are respectively pressed by the pressure rollers 31. Then, by driving the forward and reverse rotation of the lead screw 32 through the motor A35, the two sliders 33 can be controlled to close, so as to control the left and right vertical retaining rollers 34 to bind the flat wire 20 at the center position from both sides. The electric heating tube 14 is strip-shaped and is arranged along the flat wire 20. At the same time, the motor B42 synchronously drives the two fans 41 to rotate through the transmission of two pairs of bevel gears. The two fans 41 are located at both ends of the box body 11 and have opposite wind directions, so that the air flow can circulate in the oven 10, ensuring uniform heat in the oven 10, which is beneficial to the uniform heating of the surface of the flat wire 20. When the flat wire 20 passes through, it will automatically twist inside the oven 10 to achieve uniform heating, avoiding the cost problem caused by the rotation of the oven 10. In summary, the guiding member 30 is used to guide the flat wire 20 to reduce the air leakage at both ends of the oven 10 and reduce energy consumption. The guiding member 30 also makes the flat wire 20 twist 360 degrees when passing through the oven 10 for uniform heating. Compared with the rotation mode of the drying tube, the structural cost is lower, and it can also meet the requirements of high-speed wire passing. Moreover, when the flat wire 20 twists, the situation of the paint film flowing in one direction can be reduced, which is beneficial to the uniformity of the paint film.
