Abstract
Description
Technical Field
[0001] This utility model relates to the field of enameled wire production technology, and specifically to a device for applying lubricating oil to the surface of enameled wire. Background Technology
[0002] In the lubrication process of enameled wire manufacturing, a layer of lubricating oil is applied to the wire to prevent damage to the protective insulating enamel film during subsequent operations. Ideally, the amount of oil applied should be such that the wire feels smooth to the touch, but no noticeable oil is visible on the hand after touching it. Traditionally, a felt coating method is used. The felt absorbs the lubricating oil from an oil box, and as the enameled wire passes over the felt surface, the lubricating oil adheres to the wire's surface, completing the coating process.
[0003] For example, the oiling mechanism for enameled wire disclosed in patent CN102364610A has a rotating roller disposed in an oil box, so that the rotating roller is immersed in lubricating oil. The enameled wire passes through the roller groove of the rotating roller to be coated with lubricating oil. A felt structure is provided behind the rotating roller. The lubricated enameled wire passes between the upper felt and the lower felt. The felt structure brushes the lubricating oil on the surface of the enameled wire, so that the lubricating oil is more uniform, thereby improving the lubricity and wear resistance of the enameled wire surface. However, in this existing technology, the felt structure specifically involves upper and lower felts pressing the enameled wire together. The circumferential compression effect on the surface of the enameled wire is different. The upper and lower sides of the enameled wire are subjected to better compression, while the left and right sides of the enameled wire, corresponding to the seam between the upper and lower felts, are not subjected to good compression. This results in thicker lubricating oil on the left and right sides of the enameled wire, and the lubricating oil on the upper and lower sides of the enameled wire can easily escape to the left and right sides. This can easily cause uneven application of lubricating oil around the circumference of the enameled wire, resulting in localized areas with obvious oil stains and insufficient lubrication. Utility Model Content
[0004] The purpose of this invention is to provide a lubricating oil coating device for the surface of enameled wire, which solves the problem of uneven lubricating oil coating on the surface of enameled wire. By driving the coating mechanism to rotate, the coating mechanism rotates around the circumference of the enameled wire to apply lubricating oil, thereby improving the uniformity of lubricating oil coating on the surface of the enameled wire and enhancing the lubricity and wear resistance of the enameled wire surface.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lubricating oil coating device for enameled wire surface, comprising an oil tank, an oil valve, a wire guide box, and a coating device. The wire guide box is disposed on one side of the oil tank, and the oil tank has an oil port communicating with the wire guide box. The oil valve is connected to the oil port. The wire guide box has an inlet and an outlet. The coating device includes a driving mechanism and a coating mechanism. The coating mechanism is disposed inside the wire guide box. The coating mechanism includes a mounting component and a felt layer connected to the mounting component. The felt layer is located between the inlet and the outlet and corresponds to the oil port. The driving mechanism is connected to the mounting component so as to drive the felt layer to rotate around the central axis of the inlet by driving the mounting component.
[0006] In one embodiment, the felt layer is rolled up at least once to circumferentially surround the enameled wire.
[0007] In one embodiment, the felt layer abuts against the oil port so that the lubricating oil in the oil port directly enters the felt layer.
[0008] In one embodiment, the upper and lower ends of the felt layer are respectively connected to the mounting components, and the upper and lower mounting components are arranged facing each other, with the oil port corresponding to the middle of the felt layer.
[0009] In one embodiment, the mounting assembly includes a gear and a clamping seat connecting the gear. The gear has a through hole in the middle, and the clamping seat is used to clamp the felt layer. The driving mechanism is connected to the gear to drive the mounting assembly to rotate around its own central axis.
[0010] In one embodiment, the clamping seat includes a first clamping part, a second clamping part, and a moving mechanism. The gear is provided with a slide rail. The first clamping part and / or the second clamping part are slidably connected to the slide rail. The moving mechanism can drive the first clamping part and the second clamping part to move towards each other and away from each other.
[0011] In one embodiment, the gear is provided with a movable groove, the slide rail is disposed in the movable groove, and springs are respectively provided on the opposing sides of the upper and lower slide rails, the springs driving the upper and lower slide rails to move away from each other.
[0012] The advantages of this application compared to the prior art are: In this embodiment, the coating device includes a drive mechanism and a coating mechanism. The coating mechanism includes a mounting component and a felt layer. The felt layer is located between the inlet and outlet and corresponds to the oil port. Lubricating oil entering the wire guide box through the oil port can be sprayed onto the felt layer for absorption. The felt layer is connected to the mounting component, which is connected to the drive mechanism. The drive component drives the mounting component to rotate around the central axis of the inlet, thereby causing the felt layer to rotate synchronously around the central axis of the inlet. The enameled wire generally enters the wire guide box along the central area of the inlet and travels in a straight line. This achieves the circumferential rotation of the felt layer around the enameled wire, allowing the felt layer to evenly coat the lubricating oil on the surface of the enameled wire in the circumferential direction. This improves the uniformity of the lubricating oil on the surface of the enameled wire, avoids local accumulation or insufficient lubricating oil on the surface of the enameled wire, avoids obvious local oil stains and insufficient lubricating oil in some areas, ensures the lubrication effect of the enameled wire surface, and improves lubricity and wear resistance.

[0019] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.
[0020] Please refer to Figure 1 The diagram shows a side cross-sectional view of a lubricating oil coating device for enameled wire according to an embodiment of this application.
[0021] like Figure 1 As shown in the figure, an embodiment of this application discloses a lubricating oil coating device for enameled wire, including an oil tank 100, an oil valve 200, a wire guide box 300, and a coating device 400. The wire guide box 300 is disposed on one side of the oil tank 100. The oil tank 100 is provided with an oil port 110 that communicates with the wire guide box 300. The oil valve 200 is connected to the oil port 110. The wire guide box 300 is provided with a wire inlet 310 and a wire outlet 320. The coating device 400 includes a drive mechanism 410 and a coating mechanism 420. The coating mechanism 420 is disposed inside the cable box 300. The coating mechanism 420 includes a mounting assembly 430 and a felt layer 440 connected to the mounting assembly 430. The felt layer 440 is located between the cable inlet 310 and the cable outlet 320 and corresponds to the oil port 110. The drive mechanism 410 is connected to the mounting assembly 430 so as to drive the felt layer 440 to rotate around the central axis of the cable inlet 310 by driving the mounting assembly 430.
[0022] In this embodiment, the wire guide box 300 is located on one side of the oil tank 100, and the two are connected by an oil port 110. An oil valve 200 is provided inside the oil port 110. The wire guide box 300 has an inlet 310 and an outlet 320. The oil tank 100 is used to hold lubricating oil. The wire guide box 300 is for the enameled wire 500 to pass through. The oil valve 200 releases the lubricating oil in the oil tank 100 into the wire guide box 300. The coating device 400 in the wire guide box 300 then applies the obtained lubricating oil to the surface of the enameled wire 500, so that the surface of the enameled wire 500 after passing through the wire guide box 300 and leaving from the outlet 320 is coated with lubricating oil, thereby improving the lubricity and wear resistance of the enameled wire 500.
[0023] Specifically, in this embodiment, the coating device 400 includes a drive mechanism 410 and a coating mechanism 420. The coating mechanism 420 includes a mounting assembly 430 and a felt layer 440. The felt layer 440 is located between the inlet 310 and the outlet 320 and corresponds to the oil port 110. Lubricating oil entering the cable guide box 300 through the oil port 110 can be sprayed onto the felt layer 440 for absorption. The felt layer 440 is connected to the mounting assembly 430, which is connected to the drive mechanism 410. The drive assembly drives the mounting assembly 430 to rotate around the central axis of the inlet 310, thereby driving the felt layer. The felt layer 440 also rotates synchronously around the central axis of the inlet 310. The enameled wire 500 enters the wire guide box 300 roughly along the central area of the inlet 310 and travels in a straight line. This allows the felt layer 440 to rotate around the circumference of the enameled wire 500, enabling the felt layer 440 to evenly coat the lubricating oil circumferentially onto the surface of the enameled wire 500. This improves the uniformity of the lubricating oil on the surface of the enameled wire 500, avoids local accumulation or insufficient lubricating oil on the surface of the enameled wire 500, and prevents obvious local oil stains and insufficient lubricating oil. This ensures the lubrication effect on the surface of the enameled wire 500 and improves its lubricity and wear resistance. Specifically, in this embodiment, the enameled wire 500 travels in a vertical direction in the wire guide box 300. Therefore, the inlet 310 and the outlet 320 are coaxially arranged, one above the other or one below the other. The coating mechanism 420 rotates around the central axis of the inlet 310.
[0024] It should be noted that part of the oil valve 200 extends outside one side of the oil tank 100. The oil valve 200 can be a heated oil valve 200 to heat the lubricating oil. An oil level indicator 600 is provided on the other side of the oil tank 100 to indicate the oil level. In specific use, the enameled wire 500 surface lubricating oil coating device 400 of this embodiment can be electrically connected to an electrical control box to control the heating temperature and the operation of the coating device 400.
[0025] In this embodiment, the felt layer 440 can be disposed only in one direction of the circumference of the enameled wire 500. When the driving mechanism 410 drives the felt layer 440 to rotate, the felt layer 440 can cover the entire circumferential area of the enameled wire 500, applying lubricating oil to the entire circumferential surface of the enameled wire 500. However, if the speed of the enameled wire 500 is fast, the coverage of the surface of the enameled wire 500 by the felt layer 440 when it wraps around the enameled wire 500 cannot be guaranteed. Therefore, preferably, the felt layer 440 is rolled up to at least one turn to surround the enameled wire 500 circumferentially. The felt layer 440 is wound at least once to surround the enameled wire 500. The enameled wire 500 travels in the inner cavity formed by the winding of the felt layer 440. In this way, the circumferential surface of the corresponding part of the enameled wire 500 is in contact with the felt layer 440, ensuring the coverage of the circumferential surface of the enameled wire 500 by the felt layer 440 in the circumferential direction. When the felt layer 440 rotates around the central axis of the wire inlet 310, it evenly applies lubricating oil to the surface of the enameled wire 500.
[0026] In this embodiment, the oil valve 200 releases lubricating oil from the oil box into the wire box 300 through the oil port 110. Since the lubricating oil is pressurized when the oil valve 200 is open, it automatically sprays towards the felt layer 440. Alternatively, an oil gun can be installed at the oil valve 200 to ensure the spraying force and accuracy of the lubricating oil. In the embodiment where the felt layer 440 is only located on one side of the enameled wire 500 in the circumferential direction, during operation, the felt layer 440 intermittently passes through the oil port 110 as it rotates around the enameled wire 500. This allows the lubricating oil to be sprayed directly onto the felt layer 440 at times, and at other times onto the enameled wire 500 and the felt layer 440 at a distance, thus evenly coating the surface of the enameled wire 500 with lubricating oil from the felt layer 440. Preferably, in some embodiments of this application, the felt layer 440 abuts against the oil port 110, so that the lubricating oil flowing out of the oil port 110 is directly absorbed by the felt layer 440, which can promote the diffusion of the lubricating oil in the felt layer 440, so that the lubricating oil is mainly applied to the surface of the enameled wire 500 through the felt layer 440, reducing the amount of lubricating oil entering the wire guide box 300 by spraying, and further improving the uniformity of lubricating oil application. In embodiments where the felt layer 440 is only provided on one side of the circumferential direction of the enameled wire 500, the felt layer 440 abuts against the oil port 110 when rotating to approach and pass the oil port 110, while in embodiments where the felt layer 440 is rolled up to at least one turn, the felt layer 440 always abuts against the oil port 110, and relative sliding friction occurs between the felt layer 440 and the oil port 110 during rotation.
[0027] Preferably, in this embodiment, the upper and lower ends of the felt layer 440 are respectively connected to the mounting components 430, and the two mounting components 430 are arranged facing each other. The oil port 110 corresponds to the middle of the felt layer 440. In this embodiment, the upper and lower ends of the felt layer 440 are connected to the mounting components 430. The mounting components 430 are driven to rotate by the drive mechanism 410. By driving the upper and lower ends of the felt layer 440 to rotate, the entire felt layer 440 can be rotated. This ensures the stability of the felt layer 440 during rotation, reduces the shaking or even swaying of the felt layer 440 itself during rotation, and thus ensures good contact between the felt layer 440 and the surface of the enameled wire 500, avoiding poor contact between the felt layer 440 and the surface of the enameled wire 500 in some areas, thereby improving the uniformity of lubricant application. Furthermore, this design eliminates the need for the middle portion of the felt layer 440 to be connected to the mounting component 430, allowing it to be directly aligned with the oil port 110. The lubricating oil flowing out of the oil port 110 is first absorbed by the middle portion of the felt layer 440, and then diffuses to the upper and lower portions of the felt layer 440. By improving the uniformity of the lubricating oil within the felt layer 440, the uniformity of the lubricating oil applied to the surface of the enameled wire 500 by the felt layer 440 is enhanced.
[0028] Please refer to Figure 2 Preferably, in this embodiment of the application, the mounting component 430 includes a gear 431 and a clamping seat 432 connecting the gear 431. The gear 431 has a through hole 4311 in the middle. The clamping seat 432 is used to clamp the felt layer 440. The driving mechanism 410 is connected to the gear 431 to drive the mounting component 430 to rotate around its own central axis. In this embodiment, the gear 431 is horizontally positioned with its central axis vertically aligned. Therefore, the through hole 4311 in the middle of the gear 431 extends vertically, allowing the enameled wire 500 to pass through. The clamping seat 432 connected to the gear 431 clamps the upper and lower ends of the felt layer 440, ensuring the felt layer 440 is tightly attached to the surface of the enameled wire 500. This squeezes out lubricating oil from the felt layer 440 and applies it to the surface of the enameled wire 500, achieving relative fixation between the felt layer 440 and the mounting assembly 430, allowing the felt layer 440 to rotate together with the mounting assembly 430. Specifically, the driving mechanism 410 in this embodiment includes a stepper motor 411 and a transmission gear shaft 412. The transmission gear shaft 412 meshes with the gear 431 of the mounting assembly 430. After the stepper motor 411 starts, it drives the mounting assembly 430 to rotate via the transmission gear shaft 412.
[0029] Please refer to Figure 3Preferably, in this embodiment of the application, the clamping seat 432 includes a first clamping part 4321, a second clamping part 4322, and a moving mechanism 4323. The gear 431 is provided with a slide rail 4312. The first clamping part 4321 and / or the second clamping part 4322 are slidably connected to the slide rail 4312. The moving mechanism 4323 can drive the first clamping part 4321 and the second clamping part 4322 to move towards each other and away from each other. The first clamping part 4321 and / or the second clamping part 4322 are slidably connected to the slide rail 4312. The first clamping part 4321 and / or the second clamping part 4322, which can slide on the slide rail 4312, are powered by the moving mechanism 4323. The moving mechanism 4323 can be an electric actuator. In use, the electric actuator is activated, causing the first clamping part 4321 and the second clamping part 4322 to press the felt layer 440 onto the surface of the enameled wire 500. Then, the drive mechanism 410 is activated to drive the mounting assembly 430 to rotate, thereby causing the felt layer 440 to rotate around the enameled wire 500 for lubricant application. Of course, in some embodiments, the felt layer 440 and the clamping seat 432 are bonded together with adhesive to avoid relative movement between the felt layer 440 and the clamping seat 432, ensuring that the felt layer 440 rotates together with the mounting assembly 430. The moving mechanism 4323 can be fixed on the slide rail 4312, and a through hole can be provided in the middle of the slide rail 4312 for the enameled wire 500 to pass through.
[0030] Furthermore, in a preferred embodiment of this application, the gear 431 is provided with a movable groove 4313, the slide rail 4312 is provided in the movable groove 4313, and the upper and lower slide rails 4312 are respectively provided with springs 4314 on opposite sides, the springs 4314 driving the upper and lower slide rails 4312 to move away from each other. In this embodiment, springs 4314 are provided on the opposing sides of the upper and lower slide rails 4312. The upper spring 4314 pushes the upper slide rail 4312 upward, and the lower spring 4314 pushes the lower slide rail 4312 downward, so that the upper and lower slide rails 4312 tend to move away from each other. This causes the clamping part connecting the slide rails 4312 to also move with the slide rails 4312, so that the upper and lower clamping parts tend to move away from each other. In this way, the upper and lower clamping parts stretch and tighten the felt layer 440 in the vertical direction, preventing the middle area of the felt layer 440 from becoming loose due to moving away from the clamping part. That is, it improves the degree of compression between the middle area of the felt layer 440 and the enameled wire 500, so that the entire felt layer 440 has a good compression effect on the enameled wire 500 from top to bottom, thereby further improving the uniformity of lubricant application.
[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
