Description

Technical Field

[0001] This utility model belongs to the field of enameled wire production technology, specifically an enameled wire oiling device. Background Technology

[0002] In the production and processing of enameled wire, in order to ensure its insulation performance and reduce friction loss during subsequent use, it is usually necessary to coat the surface of the enameled wire with oil.

[0003] For example, a wire oiling device with authorization announcement number CN215815393U and application date of July 20, 2021, is published on the patent website. It includes a frame, an oiling base, a first support wheel, a second support wheel, and a protective cover. A felt for oiling the enameled wire is fixed on the oiling base. Both the first and second support wheels are rotatably mounted on the oiling base, with the felt positioned between them. The enameled wire passes through the first support wheel, the felt, and the second support wheel. The protective cover is fixed to the frame, and the first support wheel, the felt, and the second support wheel are all located inside the protective cover. The device utilizes the first and second support wheels to stably pass the enameled wire through the felt for oiling. This device performs continuous oiling of the enameled wire by applying oil with a felt. Because the oil has a certain viscosity, when the felt is in contact with the enameled wire roller for a long time, some burrs can easily break off and adhere to the surface of the enameled wire, thus affecting the coating quality.

[0004] Therefore, there is an urgent need to provide an improved enameled wire coating device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing oiling devices, such as burrs that are easy to fall off and adhere, the purpose of this utility model is to provide an improved enameled wire oiling device.

[0006] The technical implementation scheme of this utility model is as follows: an enameled wire coating device, including a mounting frame, guide wheels spaced apart on the mounting frame, and an oil collection box disposed on one side of the mounting frame, and further including an oiling mechanism located inside the oil collection box for uniformly coating the enameled wire, the oiling mechanism including two rotating shafts rotatably disposed on the upper side inside the oil collection box, coating wheels spaced apart along the axial direction of the two rotating shafts, gears disposed at one end of the two rotating shafts and meshing with each other, and a motor disposed on the outside of the oil collection box and connected to one of the rotating shafts.

[0007] Furthermore, the oiling mechanism also includes flexible coating sheets, which are circumferentially spaced within the grooves of the coating wheel.

[0008] Furthermore, the upper side of the oil collection box is provided with a guide groove corresponding to the coating wheel.

[0009] Furthermore, it also includes a filter screen, which is detachably installed in the middle of the oil collection box to filter residual oil dripping after coating.

[0010] Furthermore, it also includes an oil storage tank, a cover plate, a liquid guide strip, and a bracket. The oil storage tank is fixed to the upper side of the mounting frame by the bracket. The cover plate is snapped onto the upper side of the oil storage tank. A liquid guide strip is inserted through the bottom of the oil storage tank, and the liquid guide strip is located directly above the coating wheel.

[0011] Furthermore, it also includes a liquid level sensor, a suction pump, an inlet pipe, and a return pipe. The liquid level sensor is located at the bottom of the oil collection box, and a suction pump is installed on the outside of the oil storage tank. The inlet end of the suction pump is connected to the bottom of the oil collection box by an inlet pipe, and the outlet end of the suction pump is connected to the top of the oil storage tank by a return pipe.

[0012] Beneficial effects: The oil in the storage tank drips onto the coating wheel through the guide strip. The starting motor drives the two shafts to rotate synchronously through the meshing of two gears, causing the oil-coated coating wheel to rotate along with the enameled wire. The flexible coating flakes distributed circumferentially on the coating wheel evenly coat the enameled wire, effectively avoiding the problem of burrs easily adhering to the brush coating, which affects the coating quality of the enameled wire. The filter screen can filter out the coating residue and collect it at the bottom of the oil collection box. When the liquid level sensor detects that the oil has reached the preset liquid level, the suction pump, together with the suction pump, draws the collected oil back to the storage tank through the inlet pipe and return pipe, thereby realizing the recycling of oil.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: The present invention provides a wire coating device, such as... Figures 1 to 5 As shown, the device includes a mounting frame 1, guide wheels 2 spaced apart on the mounting frame 1, an oil collection box 3 located on the upper right side of the mounting frame 1, and an oiling mechanism located inside the oil collection box 3 for uniformly coating the enameled wire a. The oiling mechanism includes two rotating shafts 4 rotatably mounted inside the upper side of the oil collection box 3, coating wheels 40 spaced apart along the axial direction of the two rotating shafts 4, gears 42 located at one end of the two rotating shafts 4 and meshing with each other, and a motor 43 located outside the oil collection box 3 and connected to one of the rotating shafts 4. The oiling mechanism also includes flexible coating sheets 41, with flexible coating sheets 41 spaced apart circumferentially within the grooves of the coating wheels 40. The plate 41 has an arc-shaped protrusion structure, which can evenly divide the wire groove inside the coating wheel 40 into several liquid collection tanks. Then, through the driving action of the motor 43 and the gear 42, the coating wheels 40 on the upper and lower sides of the coaxial axis are driven to rotate synchronously in opposite directions, so as to accurately pour the oil in the liquid collection tank onto the surface of the enameled wire a, thereby achieving the purpose of uniformly coating the enameled wire a. The upper side of the oil collection box 3 is provided with wire passage grooves 30 corresponding to the coating wheel 40, which are used to allow multiple enameled wires a to pass through at the same time. It also includes a filter screen 44, which is detachably installed in the middle of the oil collection box 3 to filter the residual oil dripping after coating, so as to achieve the purpose of recycling.

[0021] like Figures 1 to 5 As shown, it also includes an oil storage tank 5, a cover plate 50, a liquid guide strip 51, and a bracket 52. The oil storage tank 5 is fixed to the upper side of the mounting frame 1 by the bracket 52. The cover plate 50 is snapped onto the upper side of the oil storage tank 5. The liquid guide strip 51 is inserted through the bottom of the oil storage tank 5 and is located directly above the coating wheel 40 for online real-time replenishment of the coated oil.

[0022] like Figure 4 and Figure 5 As shown, it also includes a liquid level sensor 45, a suction pump 6, an inlet pipe 60, and a return pipe 61. The liquid level sensor 45 is located at the bottom of the oil collection box 3. The suction pump 6 is installed on the outside of the oil storage tank 5. The inlet end of the suction pump 6 is connected to the bottom of the oil collection box 3 by an inlet pipe 60. The outlet end of the suction pump 6 is connected to the upper side of the oil storage tank 5 by a return pipe 61, which is used to recycle the filtered and collected oil.

[0023] In use, the enameled wire a is wound from left to right and sequentially connected to the three sets of guide rollers 2 on the left side. It then passes through the wire guide groove 30 on the oil collection box 3 and emerges between the two sets of coating rollers 40. Finally, it is wound onto the guide roller 2 on the right side and pulled by a traction machine. Oil is added to the oil storage tank 5, and the oil drips onto the coating rollers 40 below via the guide strip 51. The motor 43 is started, and the meshing transmission of the two gears 42 drives the two rotating shafts 4 to rotate synchronously. This causes the two sets of coating rollers 40, which are coated with oil, to rotate along the gradually pulled enameled wire a. The circumferentially distributed... The flexible coating sheet 41 can evenly coat the oil onto the enameled wire a, thus effectively avoiding the problem of burrs adhering to the enameled wire a when using a brush to coat the oil, which would affect the coating quality. The filter screen 44 can filter the oil remaining after coating and collect it at the bottom of the oil collection box 3. When the liquid level sensor 45 detects that the collected oil has reached the preset liquid level, it feeds a signal back to the controller, which then controls the suction pump 6 to start and draw the collected oil upwards through the inlet pipe 60 and the return pipe 61 into the oil storage tank 5, thereby realizing the recycling and reuse of the oil.

[0024] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims.
