Description

Technical Field

[0001] This utility model relates to a lubrication device for enameled wire, and more particularly to a lubrication device for enameled wire surface with adjustable coating amount. Background Technology

[0002] Currently, lubrication devices for enameled wire mainly consist of a lubricating oil roller and a felt mat. In operation, the lubricating oil roller first applies lubricating oil to the surface of the enameled wire by rotating, and then the felt mat wipes the wire to remove excess lubricating oil and ensure even application. However, this lubrication method has a drawback: although manufacturers can control the amount of lubricating oil applied to the wire by adjusting the rotation speed of the lubricating oil roller, the amount of lubricating oil on the wire's surface after wiping with the felt mat can easily differ from the intended coating effect, thus increasing the difficulty for manufacturers to adjust the amount of lubricating oil on the wire's surface.

[0003] Based on this, when manufacturing transformers, manufacturers need to wrap tape around the surface of the enameled wire after it has been wound into shape. This tape serves to insulate, fix, and protect the enameled wire, ensuring stable transformer operation. This necessitates controlling the amount of lubricating oil on the surface of the enameled wire during the initial coating process. On the one hand, it needs to ensure the lubricity of the enameled wire to prevent frictional damage during processing, storage, and winding; on the other hand, it needs to avoid excessive lubricating oil causing the tape to fail to adhere. Under these constraints, it is difficult for manufacturers to control the amount of lubricating oil on the surface of the enameled wire to guarantee its effectiveness when used in transformers.

[0004] Therefore, existing enameled wire lubrication devices suffer from low precision in controlling the amount of lubricating oil applied. Utility Model Content

[0005] The purpose of this invention is to provide a lubrication device for enameled wire surfaces with adjustable coating amount. It improves the control over the amount of lubricating oil applied to the enameled wire surface.

[0006] The technical solution of this utility model is: an enameled wire surface lubrication device with adjustable coating amount, including a lubricating oil tank, a lubrication mechanism in the lubricating oil tank, an oil baffle box on one side of the lubricating oil tank, and multiple wire passages for the enameled wire to extend into the top of the oil baffle box. A first guide wheel group, a wiping roller and a second guide wheel group are arranged sequentially in the oil baffle box along the wire passage direction. The surface of the wiping roller is covered with a cleaning sheet, and one end of the wiping roller extends to the outside of the oil baffle box and is connected to a drive motor.

[0007] In the aforementioned adjustable coating amount enameled wire surface lubrication device, the lubrication mechanism includes a lubricating oil roller, the surface of which is provided with multiple lubricating oil grooves arranged side by side, and one end of the lubricating oil roller is connected to a lubrication motor via a gear transmission mechanism.

[0008] In the aforementioned adjustable coating amount enameled wire surface lubrication device, the first guide wheel group and the second guide wheel group have the same structure, both including multiple guide wheels arranged side by side along the length direction of the oil baffle box, and the inner side of the guide wheel is rotatably connected to the mounting shaft, and the two ends of the mounting shaft are connected to the oil baffle box.

[0009] In the aforementioned adjustable coating amount enameled wire surface lubrication device, the wire routing port includes a first opening located side by side on the top of the oil baffle box and a second opening symmetrically arranged on the front and rear sides of the oil baffle box. The first opening and the second opening are interconnected. The lower end of the second opening is provided with a wire routing hole, and the outer diameter of the wire routing hole is larger than the first opening, the second opening, and the width.

[0010] In the aforementioned adjustable coating amount enameled wire surface lubrication device, the two ends of the oil baffle box are detachably connected to the support frame via support members, the bottom of the oil baffle box is detachably connected to the base, and a gap is left between the base and the support frame.

[0011] Compared with the prior art, this utility model has the following characteristics:

[0012] (1) This utility model can limit and guide the enameled wire by the cooperation of the first guide wheel group and the second guide wheel group, so that the enameled wire passes horizontally from above the wiping roller; by the structural cooperation of the wiping roller, the cleaning plate and the drive motor, the wiping roller can adjust the contact area between the cleaning plate and the enameled wire by changing its own rotation speed, thereby adjusting the wiping effect of the cleaning plate on the enameled wire. That is, the larger the contact area, the stronger the removal effect of the cleaning plate on the lubricating oil on the surface of the enameled wire, and the smaller the amount of lubricating oil coated on the enameled wire.

[0013] (2) By limiting the structure of the oil baffle box, the oil baffle box can block the inner guide wheel, preventing the lubricating oil on the surface of the enameled wire from being thrown out to the surroundings with the rapid rotation of the guide wheel after it adheres to the surface of the guide wheel, thereby improving the lubrication effect.

[0014] (3) By limiting the structure of the oil baffle box, support frame and base, the oil baffle box can intercept the splashed lubricating oil and allow it to flow naturally into the base below. Operators can disassemble and clean the base regularly, thereby improving the stability of this utility model.

[0015] Therefore, this invention can improve the control effect on the amount of lubricating oil coated on the surface of enameled wire. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0020] Example. An enameled wire surface lubrication device with adjustable coating amount, configured as follows: Figure 1 As shown, the device includes a lubricating oil tank 1, which contains a lubrication mechanism. An oil baffle box 2 is located on one side of the lubricating oil tank 1. Multiple wire passages 3 for enameled wires to pass through are arranged side-by-side on the top of the oil baffle box 2. A first guide wheel assembly, a wiping roller 4, and a second guide wheel assembly are sequentially arranged inside the oil baffle box 2 along the wire passage direction. The surface of the wiping roller 4 is covered with a cleaning sheet 5, which can be made of felt or sponge. Multiple slits for the enameled wire to pass through can be opened side-by-side on the cleaning sheet 5, allowing the cleaning sheet 5 to wipe the surrounding area after the wire passes through the center of the slits, ensuring effective wiping. One end of the wiping roller 4 extends to the outside of the oil baffle box 2 and is connected to a drive motor. The drive motor's speed can be adjusted via a frequency converter, thereby adjusting the contact length between the cleaning sheet 5 and the enameled wire when it passes through.

[0021] The rotation direction and speed of the wiping roller 4 can be adjusted as needed. When the rotation direction of the wiping roller 4 is in the same direction as the wire routing direction, the faster the speed of the wiping roller 4, the shorter the contact length between the cleaning plate 5 and the wire, until the wiping roller 4 and the wire reach a relatively stationary state. When the rotation direction of the wiping roller 4 is opposite to the wire routing direction, the faster the speed of the wiping roller 4, the longer the contact length between the cleaning plate 5 and the wire, and the less lubricating oil is retained on the wire after wiping.

[0022] The lubrication mechanism includes a lubricating oil roller 6, with multiple oil grooves arranged side by side on the surface of the lubricating oil roller 6. The lower end of the lubricating oil roller 6 is immersed in the lubricating oil in the lubricating oil groove 1. One end of the lubricating oil roller 6 is connected to a lubrication motor via a gear transmission mechanism. The lubrication motor can adjust its own speed through a frequency converter, thereby controlling the amount of lubricating oil applied to the enameled wire.

[0023] The first guide wheel group and the second guide wheel group have the same structure, both including multiple guide wheels 7 arranged side by side along the length of the oil baffle box 2. Each guide wheel 7 corresponds to an enameled wire. When in use, the guide wheel 7 rotates with the enameled wire. The inner side of the guide wheel 7 is rotatably connected to the mounting shaft 8, and both ends of the mounting shaft 8 are connected to the oil baffle box 2.

[0024] The wiring port 3 includes a first opening 301 located side-by-side on the top of the oil baffle box 2 and a second opening 302 symmetrically arranged on the front and rear sides of the oil baffle box 2. The first opening 301 and the second opening 302 are interconnected. The lower end of the second opening 302 is provided with a circular wiring hole 303. The width of the first opening 301 and the second opening 302 is slightly larger than the diameter of the enameled wire. The outer diameter of the wiring hole 303 is larger than the width of the first opening 301 and the second opening 302. When the enameled wire is being routed, it passes through the middle of the wiring hole 303. The wiring hole 303 can prevent the enameled wire from contacting the side wall of the oil baffle box 2 during the route. When the lubrication device is in use, a felt sheet can be placed on the top of the oil baffle box 2 to prevent lubricating oil from splashing outward from the first opening 301.

[0025] The oil baffle box 2 is bolted to both ends of the support frame 10 via the support member 9. The bottom of the oil baffle box 2 is connected to the base 11. The base 11 and the oil baffle box 2 are nested inside and outside and connected to each other by self-tapping screws or pins. There is a gap between the base 11 and the support frame 10. When cleaning, the operator can directly remove the connecting parts and pull the base 11 out from under the oil baffle box 2.

[0026] The working principle of this invention is as follows: In use, lubricating oil is first applied to the surface of the enameled wire through the cooperation of the lubricating oil tank 1 and the lubrication mechanism. After being soaked in lubricating oil, the wire enters the oil-retaining box 2. Once inside the box 2, the surface of the wire is wiped by the cooperation of the wiping roller 4 and the cleaning plate 5, thereby removing some of the lubricating oil. Based on this, the manufacturer can adjust the rotation speed of the wiping roller 4, thereby changing the contact length between the cleaning plate 5 and the wire, and the wiping effect on the lubricating oil surface, thus achieving adjustment of the amount of lubricating oil applied to the wire surface.

[0027] During the wire routing process, the guide wheels 7 on both sides of the wiping roller 4 can guide and limit the height of the enameled wire, thereby ensuring the wiping effect of the cleaning plate 5 on the enameled wire and preventing excessive separation or excessive pressing between the enameled wire and the cleaning plate 5. The cooperation between the oil baffle box 2 and the wire routing port 3 can block the inner guide wheel 7, thereby preventing the guide wheel 7 from splashing outwards as it rotates after the lubricating oil on the surface of the enameled wire adheres to it, thus ensuring the cleanliness of the surrounding environment.
