Description

Technical Field

[0001] This utility model relates to the field of enameled wire production technology, specifically to an eccentricity detection and adjustment device for controlling the uniformity of the enameled wire coating. Background Technology

[0002] Enamelled wire is a type of conductor with an insulating enamel coating on its surface. It is widely used in electrical equipment such as motors and transformers. As the performance requirements of electrical equipment continue to increase, the uniformity of the enamel coating on enamelled wire has become an important factor affecting its insulation performance and service life. During the production process of enamelled wire, due to limitations in equipment precision or process control, enamel coating eccentricity can easily occur, leading to a decrease in insulation performance or even equipment failure. Therefore, it is necessary to utilize eccentricity detection and adjustment devices to control the uniformity of the enamel coating on enamelled wire.

[0003] The existing technology has the following problems:

[0004] Existing methods for detecting the uniformity of the enameled wire coating typically rely on manual sampling or simple mechanical devices, which makes it difficult to detect eccentricity issues in real time and is also not convenient for automatically removing dust and impurities that adhere to the wire during transport, causing these impurities to stick to the wire surface and affect the coating effect. Utility Model Content

[0005] The purpose of this invention is to provide an eccentricity detection and adjustment device for controlling the uniformity of the enameled wire coating, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an eccentricity detection and adjustment device for controlling the uniformity of enameled wire coating, comprising a housing, an enameled wire body disposed inside the housing, with both ends of the enameled wire body extending out from both sides of the housing, a feed pulley rotatably connected to the inside of the housing, a discharge pulley rotatably mounted inside the housing on one side of the feed pulley, a first support wheel and a second support wheel rotatably connected to the inside of the housing below the feed pulley and the discharge pulley, the feed pulley, the first support wheel, the second support wheel and the discharge pulley all providing rolling support for the enameled wire body, a fixing frame fixedly mounted inside the housing below the discharge pulley, and a support roller rotatably mounted inside the fixing frame. A movable plate is slidably installed inside the fixed frame on one side of the support roller. A movable roller is rotatably installed inside the movable plate. The support roller and the movable roller respectively provide rolling support for both sides of the enameled wire body. A miniature displacement sensor is fixedly connected inside the fixed frame on one side of the movable plate. The output end of the miniature displacement sensor is fixedly connected to the outside of the movable plate. A fixed cylinder is fixedly installed inside the box below the fixed frame. A heating rod is fixedly connected inside the fixed cylinder. Both the fixed cylinder and the heating rod are located around the enameled wire body. A support frame is fixedly installed on one side of the box. Two brush cylinders are rotatably connected inside the support frame through two rotating rods. The two brush cylinders are located at the top and bottom of the enameled wire body, respectively.

[0007] Preferably, a servo motor is fixedly installed on the front side of the box, and the output end of the servo motor is fixedly connected to the shaft of the discharge pulley.

[0008] Preferably, the two sides of the box body are provided with fixing grooves, and the two ends of the enameled wire body extend out of the two sides of the box body through the two fixing grooves respectively.

[0009] Preferably, the axis of the feed pulley is connected to the axis of a rotating rod via a belt drive, and the belt is located on the front side of the housing.

[0010] Preferably, the fixed cylinder and the housing are fixedly connected by multiple support rods, and the miniature displacement sensor and the fixed frame are fixedly installed by a support plate.

[0011] Preferably, the front and rear sides of the fixed frame are provided with sliding grooves, and the movable plate and the fixed frame are slidably connected through the sliding grooves.

[0012] Preferably, a thrust spring is fixedly connected between the movable plate and the support plate, and the two rotating rods are connected by a gear disk transmission.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the coordinated arrangement of support rollers, movable rollers, movable plates, fixed frames, feeding pulleys, and brush cylinders, paint is introduced into the box, submerging the first and second support rollers. The discharge pulleys rotate to transport the enameled wire body. As the enameled wire body passes the bottom of the first and second support rollers and is conveyed to the right, it is immersed in the paint, allowing the paint to adhere to its surface. Then, the enameled wire body passes through the fixed cylinder for heating and drying, causing the paint to solidify and form a paint film around the wire body, facilitating the drying of the enameled wire body. During the painting process, as the enameled wire is conveyed upwards through the inner side of the fixed frame, a support roller provides rolling support on one side of the wire, while a movable roller provides rolling support on the other side. The thrust of a thrust spring allows the movable plate and roller to move easily left and right, ensuring the movable roller remains in contact with one side of the wire and provides rolling support. When the thickness of the paint coating on the wire changes, the diameter of the wire changes synchronously. By using the movable roller to roll along the wire, the paint coating on the wire surface is successfully completed. When the thickness changes, the movable plate moves left and right. When the movable roller and movable plate move to the right, the paint thickness on the surface of the enameled wire body is thicker. Then, the rotation speed of the discharge pulley is reduced, and the conveying speed of the enameled wire body is also reduced. This allows the paint adhering to the surface of the enameled wire body to flow downwards, thus reducing the paint thickness. When the movable roller moves to the left, the paint on the surface of the enameled wire body is thinner. By increasing the conveying speed of the enameled wire body, the thickness of the paint adhering to the surface of the enameled wire body can be increased, allowing for real-time adjustments. The thickness of the enamel film on the surface of the enameled wire is monitored and adjusted to make the enamel film thickness more uniform. When the enameled wire is conveyed, it drives the feed pulley to rotate, which in turn drives the brush cylinder above the enameled wire to rotate. The two brush cylinders can rotate synchronously, allowing them to remove dust and impurities adhering to the surface of the enameled wire, thus preventing dust and impurities from affecting the coating effect. The resistance generated by the rotation of the feed pulley and brush cylinder can apply a certain tension to the enameled wire to prevent it from bending or becoming scattered.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides, for example Figure 1-5 The device shown is an eccentricity detection and adjustment device for controlling the uniformity of enameled wire coating. It includes a housing 1, with an enameled wire body 2 disposed inside the housing 1. Both ends of the enameled wire body 2 extend outwards from both sides of the housing 1. A feed pulley 7 is rotatably connected to the inside of the housing 1. A discharge pulley 10 is rotatably mounted on the inside of the housing 1 on one side of the feed pulley 7. A first support wheel 8 and a second support wheel 9 are rotatably connected to the inside of the housing 1 below the feed pulley 7 and the discharge pulley 10. The feed pulley 7, the first support wheel 8, the second support wheel 9, and the discharge pulley 10 all provide rolling support for the enameled wire body 2. A fixing frame 13 is fixedly mounted on the inside of the housing 1 below the discharge pulley 10. A support roller 15 is rotatably mounted on the inside of the fixing frame 13 on one side of the support roller 15. A movable plate 16 is mounted on the movable plate 16, and a movable roller 18 is rotatably mounted on the inner side of the movable plate 16. The support roller 15 and the movable roller 18 respectively provide rolling support for both sides of the enameled wire body 2. A miniature displacement sensor 20 is fixedly connected to the inner side of the fixed frame 13 on one side of the movable plate 16. The output end of the miniature displacement sensor 20 is fixedly connected to the outer side of the movable plate 16. A fixed cylinder 11 is fixedly mounted on the inner side of the box 1 below the fixed frame 13. A heating rod 17 is fixedly connected to the inner side of the fixed cylinder 11. The fixed cylinder 11 and the heating rod 17 are both located on the periphery of the enameled wire body 2. A support frame 6 is fixedly mounted on one side of the box 1. Two brush cylinders 23 are rotatably connected to the inner side of the support frame 6 through two rotating rods 22. The two brush cylinders 23 are located at the top and bottom of the enameled wire body 2 respectively.

[0023] A servo motor 4 is fixedly installed on the front side of the housing 1, and the output end of the servo motor 4 is fixedly connected to the shaft of the discharge pulley 10.

[0024] Both sides of the housing 1 are provided with fixing grooves 3, and the two ends of the enameled wire body 2 extend out of the two sides of the housing 1 through the two fixing grooves 3 respectively.

[0025] The shaft of the feed pulley 7 is connected to the shaft of a rotating rod 22 via a belt 5, which is located at the front of the housing 1.

[0026] The fixed cylinder 11 is fixedly connected to the housing 1 by multiple support rods 12, and the miniature displacement sensor 20 is fixedly installed to the fixed frame 13 by a support plate 19.

[0027] The front and rear sides of the fixed frame 13 are provided with sliding grooves 14, and the movable plate 16 is slidably connected to the fixed frame 13 through the sliding grooves 14.

[0028] A thrust spring 21 is fixedly connected between the movable plate 16 and the support plate 19, and the two rotating rods 22 are connected by a gear disk 24.

[0029] The working principle of the eccentricity detection and adjustment device for controlling the uniformity of the enameled wire coating based on the embodiment is as follows: one end of the enameled wire body 2 is inserted into the housing 1 through the left fixed groove 3, and then one end of the enameled wire body 2 extends downward from the inside of the two feed pulleys 7. One end of the enameled wire body 2 passes to the right through the bottom of the first support wheel 8 and the second support wheel 9, and then one end of the enameled wire body 2 passes upward from the inside of the fixed cylinder 11. One end of the enameled wire body 2 passes upward through the inside of the support roller 15 and the movable roller 18. Finally, one end of the enameled wire body 2 passes upward from the inside of the two discharge pulleys 10, and one end of the enameled wire body 2 extends out of the housing 1 from the right fixed groove 3.

[0030] By introducing paint into the housing 1, the paint submerges the first support wheel 8 and the second support wheel 9. The servo motor 4 is model MHMFO92L1V2M. By starting the servo motor 4, the discharge pulley 10 can be rotated, so that the discharge pulley 10 conveys the enameled wire body 2, and the enameled wire body 2 is conveyed downward through the two feed pulleys 7. At the same time, the enameled wire body 2 is conveyed to the right through the bottom of the first support wheel 8 and the second support wheel 9.

[0031] When the enameled wire body 2 is conveyed to the right through the bottom of the first support wheel 8 and the second support wheel 9, the enameled wire body 2 can be immersed in the enamel, so that the enamel adheres to the surface of the enameled wire body 2. Then, the enameled wire body 2 is moved through the fixed cylinder 11. By energizing the heating rod 17, the heating rod 17 generates heat, which can heat and dry the enameled wire body 2 that has passed through the fixed cylinder 11, so that the enamel solidifies on the outside of the enameled wire body 2 to form a enamel film, which facilitates the painting operation of the enameled wire body 2.

[0032] As the enameled wire body 2 is conveyed upward through the inner side of the fixed frame 13, the support roller 15 provides rolling support on one side of the enameled wire body 2, and the movable roller 18 provides rolling support on the other side of the enameled wire body 2. Through the pushing action of the thrust spring 21, the movable plate 16 and the movable roller 18 can be easily moved left and right, so that the movable roller 18 can always be in contact with one side of the enameled wire body 2 and provide rolling support to the enameled wire body 2. When the thickness of the coating on the surface of the enameled wire body 2 changes, the diameter of the enameled wire body 2 changes synchronously. By using the movable roller 18 to provide rolling support along the enameled wire body 2, the movable plate 16 can be moved left and right when the coating thickness on the surface of the enameled wire body 2 changes.

[0033] When the enameled wire body 2 moves to the right along with the movable roller 18 and movable plate 16, the paint coating on the surface of the enameled wire body 2 is thicker. Then, the rotation speed of the discharge pulley 10 is reduced, and the conveying speed of the enameled wire body 2 is also reduced. This allows the paint adhering to the surface of the enameled wire body 2 to flow downwards, thereby reducing the thickness of the paint coating on the surface of the enameled wire body 2. When the movable roller 18 moves to the left, the paint coating on the surface of the enameled wire body 2 is thinner. By increasing the conveying speed of the enameled wire body 2, the thickness of the paint adhering to the surface of the enameled wire body 2 can be increased. The thickness of the paint film on the surface of the enameled wire body 2 can be monitored and adjusted in real time, making the paint film thickness on the surface of the enameled wire body 2 more uniform.

[0034] The micro displacement sensor 20 can be supported and fixed by the support plate 19. The model of the micro displacement sensor 20 is SMW-GSC-XS. The micro displacement sensor 20 can be used to monitor the distance of movement of the movable plate 16, and then the monitored data is sent to the control terminal for display, so as to facilitate real-time monitoring of the thickness of the paint film when the enameled wire is coated.

[0035] When the feed pulley 7 rotates, it drives the brush cylinder 23 above the enameled wire body 2 to rotate via the belt 5. The bottom of the brush cylinder 23 rotates to the left. The gear disc 24 drives the two rotating rods 22 to rotate synchronously, causing the bottom of the two brush cylinders 23 to rotate to the left. This removes dust and impurities adhering to the surface of the enameled wire body 2, preventing them from affecting the coating effect. The resistance generated by the rotation of the feed pulley 7 and the brush cylinder 23 applies a certain tension to the enameled wire body 2, preventing it from bending or becoming scattered.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
