Description

Technical Field

[0001] This application relates to the field of enameled wire production, and more particularly to an oiling device for an enameling machine. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. After production, enameled wire typically undergoes a winding process, and before winding, the surface is usually coated with oil.

[0003] In related technologies, Chinese Patent No. CN207199373U discloses an enameled wire oiling device, including a roller oiling device, a felt oiling device, and a wire breakage oil quantity control module. The roller oiling device and the felt oiling device cooperate with each other and are both electrically connected to the wire breakage oil quantity control module. The roller oiling device includes a lubricating oil tank, roller support seats installed on both sides inside the lubricating oil tank, and an oil supply roller installed on the roller support seats. The felt oiling device includes support frames arranged on both sides of the lubricating oil tank, support shafts installed on the support frames, mounting blocks installed on the support shafts, and several felt blocks embedded in the mounting blocks. Several wire-passing holes are opened on the mounting blocks.

[0004] In use, the enameled wire passes through the threading hole, and then the oil supply roller is driven to rotate. Because the bottom of the oil supply roller is submerged in lubricating oil, the lubricating oil can be absorbed onto the surface of the oil supply roller. Then, the felt block is pressed down to contact the oil supply roller, and the lubricating oil absorbed on the oil supply roller can be absorbed onto the felt block and spread throughout the entire felt block. When the enameled wire passes through the felt block, the lubricating oil can be evenly coated onto the enameled wire.

[0005] The oil supply roller has most of its surface exposed, resulting in a large amount of lubricating oil evaporating from it, which leads to resource waste and uneven distribution of lubricating oil on the roller. This, in turn, results in uneven distribution of lubricating oil adsorbed on the felt block, which can easily lead to uneven lubricating oil adhesion on some enameled wire surfaces. Therefore, this issue needs to be improved. Summary of the Invention

[0006] To improve the problem of uneven lubricant adhesion on the surface of enameled wire, this application provides an oiling device for an enameling machine.

[0007] The oiling device for an enameling machine provided in this application adopts the following technical solution: An oiling device for an enameling machine, used for oiling enameled wire, comprising: Work rack; An oil storage box is horizontally mounted on the work frame, with an opening at the top, and is capable of storing oil. A conveying roller is horizontally mounted inside the oil storage box. The end of the conveying roller is rotatably connected to the inner wall of the oil storage box. The bottom of the conveying roller can be submerged in the oil inside the oil storage box. The top of the conveying roller extends out of the top opening of the oil storage box and blocks the top opening of the oil storage box. The enameled wire can abut against the top of the conveying roller. An oil tank is located on the work frame. The oil tank is connected to an oil storage box via an oil supply pipe. The oil supply pipe is used to transport oil from the oil tank to the oil storage box. A drive assembly is disposed on the oil storage box. The drive assembly is connected to the conveying roller and is used to drive the conveying roller to rotate about the central axis of the conveying roller.

[0008] By adopting the above technical solution, during use, the oil supply pipe fills the oil tank into the oil storage box, where the oil settles at the bottom until the oil level submerges the bottom of the conveyor roller. At this point, the drive assembly is activated, driving the conveyor roller to rotate around its central axis. This causes the circumferential sidewall of the conveyor roller to continuously rotate into the oil storage box, contacting the oil inside. During this process, the oil in the storage box adheres to the sidewall of the conveyor roller and moves out of the storage box with it. Then, the enameled wire passes over the oil storage box, contacting the upper surface of the conveyor roller. This allows the oil on the conveyor roller to penetrate the enameled wire, achieving oil coating. Meanwhile, the conveyor roller continues to rotate, causing it to slide across the enameled wire, thus adhering the oil from the conveyor roller's entire circumference to the wire. This prevents areas from being uncoated and ensures a more uniform oil coating on the wire surface.

[0009] The top opening of the oil storage box is blocked by the conveyor roller, which reduces the contact area between the oil in the storage box and the outside world, reduces the amount of oil evaporation, saves resources, and improves the environmental protection effect of coating enameled wire.

[0010] Optionally, the conveying roller is provided with a plurality of conveying annular grooves, which are evenly arranged along the length of the conveying roller and are coaxial with the conveying roller.

[0011] By adopting the above technical solution, when the enameled wire slides on the upper surface of the conveyor roller, it moves within the conveyor annular groove. The inner wall of the conveyor annular groove abuts against the side wall of the enameled wire, providing a guiding effect and improving the stability of the wire's movement. Simultaneously, the presence of the wire within the conveyor annular groove increases the contact area between the wire and the conveyor roller, thereby increasing the amount of oil that can adhere to the wire, resulting in more uniform oil adhesion on the surface of the enameled wire.

[0012] Optionally, the driving component includes: The rotating motor is mounted on a fixed plate on the top of the oil storage box. A rotating gear is coaxially fixed to the output end of the rotating motor, which drives the rotating gear to rotate. A transmission gear is coaxially sleeved on the conveying roller, and the transmission gear is fixed to the conveying roller. The transmission gear meshes with the rotating gear.

[0013] By adopting the above technical solution, during installation, the conveying roller is inserted into the oil storage box, and at the same time, the transmission gear is moved to the bottom of the rotating gear. Then, the conveying roller is rotated and the angle is adjusted so that the transmission gear can mesh with the rotating gear. When the rotating motor is started, it drives the rotating gear to rotate, so that the transmission gear drives the conveying roller to rotate at the same time, realizing the rotation of the conveying roller, so as to achieve the effect of oil adhering to the circumferential side wall.

[0014] Optionally, two mounting plates are detachably connected to the oil storage box. The mounting plates are located at the opening of the oil storage box and are respectively located at both ends of the conveying roller. The mounting plates are used to restrict the limiting roller inside the oil storage box.

[0015] By adopting the above technical solution, after the conveyor roller is placed in the oil storage box, the mounting plate is installed on the oil storage box, thereby confining the conveyor roller within the oil storage box and realizing the installation of the conveyor roller on the oil storage box. When the conveyor roller needs to be replaced and cleaned, the mounting plate is removed from the oil storage box, leaving the top of the conveyor roller unobstructed, allowing the conveyor roller to be directly removed from the top opening of the oil storage box, realizing convenient disassembly of the conveyor roller.

[0016] Optionally, the bottom of the oil storage box is connected to a liquid level pipe, the liquid level pipe is vertically arranged, the liquid level pipe is connected to a waste oil pipe, and the waste oil pipe is equipped with a connecting valve to control the connection or closure of the waste oil pipe.

[0017] By adopting the above technical solution, when the oil pipeline delivers oil from the tank into the storage box, some oil will flow into the level pipe at the same time as the oil is stored in the storage box. The liquid level in the level pipe is level with the liquid level in the storage box, so that the operator can intuitively understand the amount of oil in the storage box through the level pipe and stop the oil pipeline in time to avoid oil overflow.

[0018] After the enameled wire is coated with oil, open the connecting valve to connect the waste oil pipe. The oil in the level pipe and the oil storage box will be discharged from the waste oil pipe to prevent the oil from settling in the oil storage box and deteriorating.

[0019] Optionally, the oil storage box is provided with an overflow pipe, which is vertically arranged. The top wall of the overflow pipe is located below the top opening of the oil storage box, and the bottom end of the overflow pipe is connected to a return pipe, which is connected to the oil tank.

[0020] By adopting the above technical solution, when the oil pipeline transports oil, the oil in the oil storage box continuously accumulates until it reaches the top of the overflow pipe. At this point, the oil will flow into the overflow pipe from the top opening and then into the return pipe. Finally, it will return to the oil tank through the return pipe. This ensures that the oil in the oil storage box will not overflow even if the operator is not paying attention, and also achieves oil circulation.

[0021] Optionally, a pressure plate is fixed to the top wall of the oil storage box by a connecting rod. The pressure plate is horizontally arranged, and the enameled wire can pass between the pressure plate and the oil storage box after passing through the conveying roller.

[0022] By adopting the above technical solution, after the enameled wire is coated with oil by the conveyor roller, the enameled wire moves out of the oil storage box from under the pressure plate. The pressure plate first restricts the enameled wire, so that the enameled wire must move downward after passing the conveyor roller. This ensures that the enameled wire can maintain contact with the conveyor roller during the movement, thereby increasing the uniformity of the oil coating on the enameled wire.

[0023] Optionally, the pressure plate is provided with an adjusting plate, which is parallel to the pressure plate. A screw is fixed on the pressure plate, and an adjusting hole is provided on the adjusting plate. The adjusting hole is arranged in a vertical direction. The screw passes through the adjusting hole and can move relative to it. A nut is fitted on the screw and is threadedly connected to it. The nut can abut against the side of the adjusting plate away from the pressure plate, and the enameled wire can pass under the adjusting plate.

[0024] By adopting the above technical solution, the nut is moved away from the adjusting plate, so that the nut is separated from the adjusting plate. Then the adjusting plate is moved up and down. During this process, the screw slides relatively in the adjusting hole, which plays a guiding role, so that the adjusting plate maintains a horizontal state. That is, the distance from each point on the bottom of the adjusting plate to the oil reservoir is changed uniformly to accommodate the passage of enameled wires for different rough milling, thus improving applicability.

[0025] Optionally, the oil storage box has several abutment blocks on the side away from the pressure plate. The abutment blocks have receiving grooves on their side walls near the conveying roller. Sponges are placed in the receiving grooves, and the sponges abut against the side walls of the conveying roller. A guide plate is provided between two adjacent abutment blocks. Several guide plates correspond one-to-one with the conveying ring grooves. The guide plates are inclined downwards in the direction near the conveying roller. Oil outlet holes are provided on the side walls of the abutment blocks near the guide plates. The oil storage box is provided with a squeezing assembly for squeezing the sponges.

[0026] By adopting the above technical solution, when the conveyor roller rotates, it first rotates to the bottom to contact and adhere to the oil in the oil storage box before rotating upwards. During this process, it passes through a sponge, which slides relative to the side wall of the conveyor roller, wiping the side wall and absorbing the oil. However, the sponge does not contact the oil in the conveying ring groove, so that only the conveying ring groove contains oil in the part of the conveyor roller that rotates out of the oil storage box, which is used for the oiling of the enameled wire. This further reduces the contact between the oil and the outside world, and achieves the goal of avoiding oil contamination and evaporation without affecting the oiling of the enameled wire.

[0027] When the sponge absorbs a large amount of oil, the extrusion assembly is activated to compress the sponge, causing it to deform and reduce its volume. This allows the oil in the sponge to seep out and flow from the oil outlet to the guide plate. The oil then falls down the guide plate until it is aligned with the conveying ring groove and poured into it. This ensures that the oil in the conveying ring groove is fully in contact with the groove, improving the uniformity of oil distribution and thus guaranteeing the uniformity of oiling the enameled wire.

[0028] Optionally, the extrusion assembly includes: A rotating rod is provided on the oil storage box, and the end of the rotating rod is rotatably connected to the oil storage box. The rotating rod can rotate about the central axis of the rotating rod. Several cams are coaxially mounted on the rotating rod. The cams are fixed to the rotating rod. Each of the cams corresponds to a contact block. The tip of the cam can contact the side of the sponge away from the conveying roller.

[0029] By adopting the above technical solution, the rotating rod is driven to rotate, which in turn drives several cams to rotate synchronously. When the tip of the cam rotates to contact the sponge, it squeezes the sponge and squeezes the oil out of the sponge through the oil outlet to the guide plate. Then, the cam continues to rotate and gradually separates from the sponge. During this process, the rotating rod always rotates in the same direction to achieve intermittent squeezing of the sponge.

[0030] In summary, this application includes at least one of the following beneficial effects: 1. During use, the oil supply pipe fills the oil storage box with oil from the oil tank. The oil settles at the bottom of the storage box until the oil level submerges the bottom of the conveyor roller. At this point, the drive assembly is activated, driving the conveyor roller to rotate around its central axis. This allows the circumferential sidewalls of the conveyor roller to pick up oil and rotate out of the storage box. The enameled wire is then passed over the storage box, bringing it into contact with the upper surface of the conveyor roller. This allows the oil on the conveyor roller to penetrate the enameled wire, achieving oil coating. During this process, the conveyor roller continues to rotate, causing it to slide across the enameled wire, thus adhering the oil from the conveyor roller to the entire circumference of the wire at a single point. This prevents any areas from being uncoated, resulting in a more even oil coating on the surface of the enameled wire. 2. The top opening of the oil storage box is blocked by the conveyor roller, thereby reducing the contact area between the oil in the storage box and the outside world, reducing the amount of oil evaporation, saving resources and improving the environmental protection effect when coating enameled wire.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an oiling device for an enameling machine. (Refer to...) Figure 1 and Figure 2 The oiling device for an enameling machine includes a work frame 10, an oil storage box 20, and a conveying roller 30. The oil storage box 20 is placed horizontally, and one end of the oil storage box 20 is fixed to the work frame 10 by bolts. The top of the oil storage box 20 is open, while the inside is hollow, used to store lubricating oil. The conveying roller 30 is inserted into the top opening of the oil storage box 20, with its top extending out of the top opening and sealing it. The conveying roller 30 is horizontally positioned, and its end is rotatably connected to the inner wall of the oil storage box 20. The bottom of the conveying roller 30 can be submerged in the oil inside the oil storage box 20. The conveying roller 30 has several conveying annular grooves 31, which are evenly arranged along the length of the conveying roller 30 and are coaxial with the conveying roller 30.

[0035] In use, the drive roller 30 rotates, causing its sidewalls and the conveying ring groove 31 to pick up oil and rotate out of the oil storage box 20. Then, the enameled wire passes over the top of the roller 30 and moves within the conveying ring groove 31, allowing the oil on the roller 30 to adhere to the wire, completing the oiling process. The wire's position within the conveying ring groove 31 increases the contact area between the wire and the roller 30, thereby increasing the amount of oil that can adhere to the wire and resulting in more uniform oil adhesion to the surface of the enameled wire.

[0036] The top opening of the oil storage box 20 is blocked by the conveying roller 30, thereby reducing the contact area between the oil in the oil storage box 20 and the outside world, reducing the amount of oil evaporation, saving resources and improving the environmental protection effect when coating enameled wire.

[0037] Reference Figure 1 and Figure 2 An oil tank 50 is installed on the work frame 10. The oil tank 50 stores oil and is connected to an oil delivery pipe 51. A C-shaped steel is fixed on the bottom wall of the oil storage box 20. The oil delivery pipe 51 passes through the C-shaped steel, which serves as a support. The end of the oil delivery pipe 51 away from the oil tank 50 extends from one end of the C-shaped steel and extends upward. Then it is inserted into the top wall of the oil storage box 20, so that the oil in the oil delivery pipe 51 flows from top to bottom into the oil storage box 20, which facilitates the filling of oil.

[0038] Reference Figure 2 and Figure 3 The oil storage box 20 is provided with a drive assembly 40 for driving the conveyor roller 30 to rotate. The drive assembly 40 includes a rotating motor 41, a rotating gear 42 and a transmission gear 43. A fixing plate 21 is fixed on the top of the oil storage box 20. The fixing plate 21 is vertically arranged. The rotating motor 41 is mounted on the fixing plate 21 by bolts. The rotating motor 41 is located on the mounting plate 22. Reference Figure 2 and Figure 3 The rotating gear 42 is coaxially fixed on the output end of the rotating motor 41. The rotating motor 41 is used to drive the rotating gear 42 to rotate. The transmission gear 43 is coaxially sleeved on the end of the conveying roller 30, and the transmission gear 43 is fixed to the conveying roller 30. The transmission gear 43 meshes with the rotating gear 42.

[0039] During installation, the conveyor roller 30 is inserted into the oil storage box 20, and the transmission gear 43 is moved to the bottom of the rotating gear 42. Then, the conveyor roller 30 is rotated and the angle is adjusted so that the transmission gear 43 can mesh with the rotating gear 42. When the rotating motor 41 is started, it drives the rotating gear 42 to rotate, so that the transmission gear 43 drives the conveyor roller 30 to rotate at the same time, realizing the rotation of the conveyor roller 30, so as to achieve the effect of oil adhering to the circumferential side wall.

[0040] Reference Figure 2 and Figure 3 Two mounting plates 22 are detachably connected to the top wall of the oil storage box 20 via bolts. The mounting plates 22 are horizontally positioned across the opening of the oil storage box 20, with each mounting plate 22 located at one end of the conveyor roller 30. When the conveyor roller 30 is placed in the oil storage box 20, the mounting plates 22 are installed on the oil storage box 20, thus confining the conveyor roller 30 within the oil storage box 20, achieving installation of the conveyor roller 30 on the oil storage box 20. When the conveyor roller 30 needs to be replaced or cleaned, the mounting plates 22 are removed from the oil storage box 20, leaving the top of the conveyor roller 30 unobstructed, allowing the conveyor roller 30 to be directly removed from the top opening of the oil storage box 20, achieving disassembly of the conveyor roller 30.

[0041] Reference Figure 1 and Figure 3 The bottom of the oil storage box 20 is connected to a level pipe 60, which is vertically installed and connected to a waste oil pipe 70. A connecting valve 71 is installed on the waste oil pipe 70 to control its opening and closing. When the oil supply pipe 51 delivers oil from the oil tank 50 into the oil storage box 20, some oil flows into the level pipe 60 simultaneously. The liquid level in the level pipe 60 is level with the liquid level in the oil storage box 20, allowing the operator to visually understand the oil level in the oil storage box 20 and promptly stop the oil supply pipe 51 to prevent overflow.

[0042] After the enameled wire is coated with oil, open the connecting valve 71 to connect the waste oil pipe 70. The oil in the liquid level pipe 60 and the oil storage box 20 will be discharged from the waste oil pipe 70 to prevent the oil from settling in the oil storage box 20 and deteriorating.

[0043] Reference Figure 1 and Figure 3 The oil storage box 20 is equipped with an overflow pipe 80, which is vertically installed. The top wall of the overflow pipe 80 is flush with the central axis of the conveying roller 30. The bottom end of the overflow pipe 80 is connected to a return pipe 81, which is connected to the oil tank 50. When the oil supply pipe 51 delivers oil, the oil in the oil storage box 20 continuously accumulates until it reaches the top of the overflow pipe 80. At this point, the oil flows into the overflow pipe 80 from the top opening and then into the return pipe 81. Finally, it returns to the oil tank 50 through the return pipe 81. This ensures that the oil in the oil storage box 20 will not overflow even when the operator is not paying attention, and also achieves oil circulation.

[0044] Reference Figure 2 and Figure 4Two vertically arranged connecting rods 23 are fixed on the top wall of the oil storage box 20. A pressure plate 90 is fixed at the top of the connecting rod 23. The pressure plate 90 is horizontally arranged. Several screws 91 are fixed on the side wall of the pressure plate 90. An adjusting plate 110 is abutted on the side wall of the pressure plate 90. The adjusting plate 110 is parallel to the pressure plate 90. Several adjusting holes 111 are opened through the adjusting plate 110. The adjusting holes 111 are arranged in the vertical direction. The several adjusting holes 111 correspond one-to-one with the screws 91. The screws 91 pass through the adjusting holes 111 and can move relative to each other in the adjusting holes 111.

[0045] Reference Figure 2 and Figure 4 A nut 911 is fitted onto the screw 91. The nut 911 is threadedly connected to the screw 91 and can abut against the side of the adjusting plate 110 away from the pressure plate 90, thereby fixing the adjusting plate 110 onto the pressure plate 90. The enameled wire that has been coated with oil passes under the adjusting plate 110. The adjusting plate 110 acts as a constraint, so that the enameled wire must move downward after passing the conveyor roller 30, so that the enameled wire can maintain abutment against the conveyor roller 30 during the movement, thereby increasing the uniformity of the oil coating on the enameled wire.

[0046] When applying oil to enameled wires of different thicknesses, move nut 911 away from adjusting plate 110 to separate nut 911 from adjusting plate 110. Then move adjusting plate 110 up and down to accommodate enameled wires with different coarse milling, thus improving applicability.

[0047] Reference Figure 4 and Figure 5 Several abutment blocks 120 are fixed on the side of the oil storage box 20 away from the pressure plate 90. Each abutment block 120 is located between adjacent conveying ring grooves 31. A receiving groove 121 is opened on the side wall of the abutment block 120 near the conveying roller 30. A sponge 130 is inserted in the receiving groove 121 and abuts against the side wall of the conveying roller 30. A guide plate 140 is fixed between two adjacent abutment blocks 120. Several guide plates 140 correspond one-to-one with the conveying ring grooves 31. The guide plates 140 are inclined downward in the direction near the conveying roller 30. An oil outlet hole 122 is opened on the side wall of the abutment block 120 near the guide plate 140 and is connected to the guide plate 140.

[0048] When the conveyor roller 30 rotates, it first rotates to the bottom to contact and adhere to the oil in the oil storage box 20 before rotating upwards. During this process, it passes through the sponge 130, which slides relative to the side wall of the conveyor roller 30 to wipe the side wall of the conveyor roller 30 and absorb the oil on the side wall. However, the position of the sponge 130 does not contact the oil in the conveying ring groove 31, so that only the conveying ring groove 31 contains oil in the part of the conveyor roller 30 that rotates out of the oil storage box 20, so as to carry out the oiling work of the enameled wire. This further reduces the contact between the oil and the outside world, and achieves the goal of avoiding oil contamination and evaporation without affecting the oiling of the enameled wire.

[0049] Reference Figure 4 and Figure 5 When the sponge 130 absorbs a lot of oil, the oil seeps out from the sponge 130 and flows from the oil outlet 122 to the guide plate 140. Then it falls down along the guide plate 140 until it is aligned with the conveying ring groove 31 and poured into the conveying ring groove 31, so that the conveying ring groove 31 is fully in contact with the oil, improving the uniformity of the oil distribution in the conveying ring groove 31, and thus ensuring the uniformity of the oil coating on the enameled wire.

[0050] Reference Figure 4 and Figure 5 The oil storage box 20 is equipped with a compression assembly 150 for compressing the sponge 130. The compression assembly 150 includes a rotating rod 151 and several cams 152. The rotating rod 151 is mounted on the oil storage box 20 by a bracket. The end of the rotating rod 151 is rotatably connected to the bracket. The rotating rod 151 is connected to the rotating motor 41 by a conveyor belt 160. That is, the driving wheel of the conveyor belt 160 is coaxially fixed with the output shaft of the rotating motor 41, and the driven wheel of the conveyor belt 160 is coaxially fixed with the rotating rod 151. When the rotating motor 41 is started, the driving wheel and the driven wheel are driven by the conveyor belt of the conveyor belt 160, so that the rotating rod 151 can rotate about the central axis of the rotating rod 151. Reference Figure 4 and Figure 5 Several cams 152 are coaxially sleeved on the rotating rod 151. The cams 152 are fixed to the rotating rod 151. The several cams 152 correspond one-to-one with the abutting block 120. The receiving groove 121 on the abutting block 120 passes through the abutting block 120 and one side of the conveying roller 30, so that the tip of the cam 152 can extend into the receiving groove 121 and abut against the side of the sponge 130 away from the conveying roller 30.

[0051] When the rotating motor 41 starts, it drives the conveying roller 30 to rotate, simultaneously causing the rotating rod 151 to rotate synchronously. This, in turn, causes several cams 152 to rotate synchronously. When the tip of the cam 152 rotates to abut against the sponge 130, it squeezes the sponge 130, causing it to deform and reduce in volume. This allows oil in the sponge 130 to seep out and flow from the oil outlet 122 onto the guide plate 140. The oil then falls down the guide plate 140, filling the conveying ring groove 31. Subsequently, the cam 152 continues to rotate, gradually separating from the sponge 130. During this process, the rotating rod 151 always rotates in the same direction, achieving intermittent compression of the sponge 130.

[0052] The implementation principle of the oiling device for an enameling machine according to an embodiment of this application is as follows: During use, the oil supply pipe 51 fills the oil tank 50 into the oil storage box 20 with oil. The oil settles at the bottom of the oil storage box 20 until the oil level in the oil storage box 20 can submerge the bottom of the conveying roller 30. At this time, the drive assembly 40 is activated, driving the conveying roller 30 to rotate around its central axis. This causes the circumferential sidewall of the conveying roller 30 to continuously rotate into the oil storage box 20 and come into contact with the oil in the oil storage box 20. During this process, the oil in the oil storage box 20 adheres to the sidewall of the conveying roller 30 and moves out of the oil storage box 20 with the conveying roller 30. At this time, the enameled wire passes over the top of the oil storage box 20, so that the enameled wire comes into contact with the upper surface of the conveying roller 30, thereby allowing the oil on the conveying roller 30 to penetrate onto the enameled wire, achieving oiling of the enameled wire. During this process, the conveyor roller 30 is still rotating, causing it to slide on the enameled wire. This allows the oil from the conveyor roller 30 to adhere to the entire circumference of the enameled wire at a point, making it less likely that there will be areas on the enameled wire that are not coated with oil. This results in a more uniform oil adhesion on the surface of the enameled wire.

[0053] The top opening of the oil storage box 20 is blocked by the conveying roller 30, thereby reducing the contact area between the oil in the oil storage box 20 and the outside world, reducing the amount of oil evaporation, saving resources and improving the environmental protection effect when coating enameled wire.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
