Description

Technical Field

[0001] This utility model relates to the field of enameled wire production technology, specifically to an enameled wire painting device with recyclable enamel liquid. 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. It must meet certain standard requirements and is affected by factors such as the quality of raw materials, process parameters, production equipment, and environment. It possesses four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] The main processes in the production of enameled wire include unwinding, annealing, varnishing, baking, cooling, lubrication, and winding. Varnishing is an indispensable part; it involves applying a certain thickness of insulating varnish to the surface of the copper wire, followed by subsequent processing to achieve insulation from the external environment. Varnished enameled wire also possesses high corrosion resistance, effectively extending the lifespan of the wire when used in humid, acidic, or alkaline environments. Varnishing enameled wire plays a crucial role in protecting the wire, improving its electrical performance, and extending its service life.

[0004] A paint recovery device for enameled wire, disclosed in announcement number CN111495657B, includes a base plate with multiple mounting holes; three first bases evenly spaced on the base plate, arranged in pairs; and two winding drums rotatably disposed between the first bases. This device overcomes the shortcomings of existing technologies, such as difficulty in adjusting the tension of the enameled wire and inability to recover excess paint, achieving the effect of adjusting the tension of the enameled wire and recovering excess paint. By placing weights on a placement plate to tighten the enameled wire, the tension can be increased; the more weights, the greater the tension. Adjusting the number of weights on the placement plate adjusts the tension of the enameled wire. However, in this technical device, the painting equipment uses a spray sleeve to spray paint onto the enameled wire in a semi-enclosed tube. However, this painting method cannot provide timely feedback on the painting effect, and the painting effect cannot be seen intuitively. The painting effect can only be recorded and observed after the painting is completed. Furthermore, after the painting is completed, the device directly pulls the wire into the winding drum. However, the paint that has not been completely cooled will cause some of the paint on the surface of the enameled wire to fall off after it bends and enters the winding drum. This will lead to uneven paint on the surface of the enameled wire, thus affecting its use. Utility Model Content

[0005] This invention provides a coating equipment for enameled wires that can recycle paint, solving the problem that the coating effect cannot be fed back in a timely and intuitive manner due to the semi-enclosed tube spraying method used in the prior art.

[0006] Secondly, it solves the problem that in the existing technology, after the enameled wire is painted, it is directly fed into the winding wheel and into the winding drum. This causes the enamel liquid that has not been fully cooled to fall off the surface of the enameled wire as it bends and enters the winding wheel, resulting in uneven enamel liquid on the surface of the enameled wire and thus affecting its use.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A touch-up paint nozzle and a paint application nozzle corresponding to the enameled wire are respectively provided at both ends of the annular tube. A touch-up paint recovery cover and a paint application recovery cover are respectively provided on one side of the touch-up paint nozzle and the paint application nozzle, and are connected by a combined pipe. The combined pipe is connected to a vacuum pump and an oil-water separator.

[0009] Preferably, the wind box is provided with a partition plate inside, which divides the internal space of the wind box equally.

The pay-off reel is close to the hot air blower, and the take-up reel is close to the cold air blower.

[0010] Preferably, the bellows is a rectangular box, and a right-angled fixing frame is provided on one side of the bellows. A winding wheel is rotatably fixed on the fixing frame, and a motor mounting frame is provided on the winding wheel. A motor is mounted on the motor mounting frame, and the motor is connected to the winding wheel.

[0011] Preferably, the annular tube is arranged parallel to the winding wheel and located at the bottom of the winding wheel. The two ends of the annular tube near the side of the air box are provided with a touch-up paint nozzle and a paint spray nozzle. The touch-up paint nozzle and the paint spray nozzle are both facing the same direction, and the touch-up paint nozzle is located at the end near the cold air blower, while the paint spray nozzle is located at the end near the hot air blower.

[0012] Preferably, both the touch-up paint recovery cover and the paint application recovery cover are spherical covers, and the touch-up paint recovery cover is oriented opposite to the touch-up paint nozzle, with the enameled wire near the touch-up paint nozzle located between the touch-up paint recovery cover and the touch-up paint nozzle. The paint application recovery cover is oriented opposite to the paint application nozzle, with the enameled wire near the paint application nozzle located between the paint application recovery cover and the paint application nozzle.

[0013] Preferably, the paint recovery hood and the paint recovery hood are connected by a combined pipe. The bottom of the combined pipe is connected to a vacuum pump, the vacuum pump is connected to an oil-water separator, and the oil-water separator is equipped with a pressure pump and is connected to a ring pipe by a hose.

[0014] Preferably, the winding reel, the unwinding reel, and the take-up reel are all located in the same plane, and enameled wire is wound between the winding reel, the unwinding reel, and the take-up reel.

[0023] 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.

[0024] Reference Figure 1 and Figure 2 This is Example 1. Figure 1 This is a schematic front view of the overall structure of Embodiment 1. Figure 2 This is a cross-sectional view of the overall structure of Embodiment 1. Embodiment 1 is a coating device for enameled wire 14 with recyclable paint liquid, including a wind box 3, which is a hollow closed box. A hot air blower 2 and a cold air blower 1 are installed on the top. A winding wheel 6 is fixed on the side of the wind box 3. Enameled wire 14 is wound on the winding wheel 6. An annular tube 9.1 is fixed at the bottom of the winding wheel 6. The two ends of the annular tube 9.1 are respectively provided with a touch-up paint nozzle 9.11 and a coating paint nozzle 9.12 corresponding to the enameled wire 14. A touch-up paint recovery cover 9.21 and a coating paint recovery cover 9.22 are respectively provided on one side of the touch-up paint nozzle 9.11 and the coating paint nozzle 9.12, and are connected by a combined pipe 9.2. The combined pipe 9.2 is connected to a vacuum pump 10 and an oil-water separator 11.

[0025] When this recyclable paint coating equipment for enameled wire 14 is in operation, the hot air blower 2 and the cold air blower 1 work simultaneously. The hot air blower 2 provides a suitable pre-coating environment for the enameled wire 14, while the cold air blower 1 rapidly cools the enameled wire 14 after coating, which is beneficial for paint adhesion and cooling. When the hot air blower 2 is working, it can heat the air in the air box 3, which raises the surface temperature of the enameled wire 14, which is beneficial for drying the surface of the enameled wire 14 and heating the surface of the enameled wire 14, which is beneficial for paint adhesion and drying.

[0026] The bottom of the enameled wire 14 on the winding wheel 6 is provided with an annular tube 9.1. The annular tube 9.1 has a touch-up paint nozzle 9.11 and a paint spray nozzle 9.12 at both ends. The touch-up paint nozzle 9.11 and the paint spray nozzle 9.12 will perform touch-up paint and paint spray operations respectively. The painting nozzle 9.12 is responsible for painting the enameled wire 14 after it is heated in the air box 3 where the hot air blower 2 is located. This allows the surface of the enameled wire 14 to be evenly coated with a layer of paint. After painting, the wire passes through the winding wheel 6 and rotates to bring the painted portion of the enameled wire 14 to the other end of the annular tube 9.1. The other end of the annular tube 9.1 is equipped with a touch-up paint nozzle 9.11. After a short period of rotation of the winding wheel 6, the wire undergoes initial cooling. The purpose of the touch-up paint nozzle 9.11 is to repair the unpainted parts of the enameled wire 14 after the short cooling period by performing a second painting to replenish the paint to the surface of the enameled wire 14, so that the paint can be evenly adhered to the surface of the enameled wire 14.

[0027] The placement of these two nozzles allows for a more precise and controllable painting process on the enameled wire 14. To ensure efficient use of the paint and reduce waste, both the touch-up nozzle 9.11 and the painting nozzle 9.12 are equipped with corresponding recovery hoods on one side. The touch-up paint recovery hood 9.21 and the painting paint recovery hood 9.22 collect excess paint generated during the spraying process and then send it through the combination pipe 9.2 to the vacuum pump 10 and the oil-water separator 11 for processing. This not only allows for the recycling and reuse of the paint but also prevents environmental pollution caused by the paint.

[0028] The enameling line painting equipment with recyclable paint liquid in this embodiment has advantages such as simple operation, good painting effect, high paint liquid utilization rate, and environmental protection and energy saving. It is suitable for enameling line painting operations in large-scale production. At the same time, its unique recycling design also enables the effective utilization of paint liquid, reduces production costs, and improves economic efficiency.

[0029] The air box 3 is provided with a partition plate inside, which divides the internal space of the air box 3 equally. A hot air blower 2 and a cold air blower 1 are respectively provided on the top of the air box 3 on both sides of the partition plate. A pay-off reel 12 and a take-up reel 13 are provided on the side of the air box 3 opposite to the winding reel 6. The pay-off reel 12 is close to the hot air blower 2, and the take-up reel 13 is close to the cold air blower 1.

[0030] Inside the bellows 3, a partition cleverly divides the space into two parts, separating hot and cold air to prevent interference. The partition design is both robust and flexible, ensuring full utilization and efficient management of the internal space of the bellows 3. The placement of the hot air blower 2 and the cold air blower 1 allows the bellows 3 to flexibly adjust the temperature as needed to meet different process requirements.

[0031] When heating or cooling of the wire is required, the hot air blower 2 and the cold air blower 1 can be quickly started, sending hot or cold air into the air box 3 through the channels on both sides of the partition plate. The wire travels inside the air box 3, and after being processed by the hot air blower 2 or the cold air blower 1 to reach the required temperature, it is then guided by the wire feeding reel 12 and the wire taking reel 13 to continue into the next process stage.

[0032] The design of the pay-off reel 12 and take-up reel 13 fully considers the wire conveying requirements. The pay-off reel 12, located near the hot air blower 2, ensures that the wire maintains stable tension during heating, preventing the wire from slack or twisting. The take-up reel 13, located near the cold air blower 1, can quickly wind up the wire after it has cooled, ensuring the wire is neat and orderly.

[0033] The design of the entire bellows 3 is both practical and efficient. Through the coordinated action of the hot air blower 2, the cold air blower 1, the partition plate, the wire feeding reel 12, and the wire take-up reel 13, rapid heating and cooling of the wire is achieved, improving production efficiency and reducing energy consumption and waste. At the same time, the bellows 3 has a compact structure, occupies little space, and is easy to install and maintain.

[0034] The air box 3 is a rectangular box, and a right-angled fixing bracket 8 is provided on one side of the air box 3. The fixing bracket 8 is located outside the air box 3 and on the side plate between the hot air blower 2 and the cold air blower 1, opposite to the side plate where the wire feeding reel 12 and the wire taking reel 13 are located. In this embodiment, the side of the air box 3 needs to have good heat insulation effect, so that the surface of the side plate of the air box 3 is stable and tends to be constant, avoiding the unstable surface temperature of the side plate of the air box 3 when the hot air blower 2 and the cold air blower 1 are working, which would affect the painting and touch-up. A winding wheel 6 is rotatably fixed on the frame 8. A motor mounting bracket 7 is provided on the winding wheel 6, and a motor 5 is mounted on the motor mounting bracket 7. The motor 5 is connected to the winding wheel 6 and is used to drive the winding wheel 6, thereby enabling the enameled wire 14 located at the winding wheel 6 to move. In order to improve the moving efficiency of the enameled wire 14 and increase the tension of the enameled wire 14 during painting, and to avoid the loose enameled wire 14 from being repeatedly painted or moving slowly and affecting efficiency, both the pay-off wheel 12 and the take-up wheel 13 are driven by the motor 5.

[0035] The annular tube 9.1 is arranged parallel to the winding wheel 6 and located at the bottom of the winding wheel 6. The two ends of the annular tube 9.1 near the side of the air box 3 are provided with a touch-up paint nozzle 9.11 and a paint spray nozzle 9.12. The touch-up paint nozzle 9.11 and the paint spray nozzle 9.12 are both facing the same direction, and the touch-up paint nozzle 9.11 is located at the end near the cold air blower 1, and the paint spray nozzle 9.12 is located at the end of the hot air blower 2.

[0036] The annular tube 9.1 has a fluid channel inside for uniformly spraying paint from the touch-up spray nozzle 9.11 and the paint spray nozzle 9.12. The design of the touch-up spray nozzle 9.11 and the paint spray nozzle 9.12 allows the paint to be precisely sprayed onto the surface of the object to be treated, thereby achieving an efficient and uniform coating effect.

[0037] At the bottom of the annular pipe 9.1, a paint inlet connected to the fluid channel is provided for introducing paint into the annular pipe 9.1. The design of the paint inlet allows the paint to flow smoothly into the annular pipe 9.1, ensuring a stable supply of paint.

[0038] The winding wheel 6 is located above the annular tube 9.1 and is set parallel to the annular tube 9.1. This facilitates the driving of the rotating enameled wire 14 on the winding wheel 6, reduces friction in different directions, and allows for easy control of the rotation speed and direction of the winding wheel 6 by pulling the enameled wire 14.

[0039] When painting is required, the cold air blower 1 and the hot air blower 2 are started first. The hot air blower 2 ensures that the enameled wire 14 has a high surface temperature before painting, which is conducive to the adhesion of the paint. The cold air blower 1 ensures that the enameled wire 14 has a low surface temperature and a high airflow speed after painting, which is conducive to cooling the paint and improving the adhesion. Then, the winding wheel 6 is driven by the motor 5 to rotate and move the enameled wire 14. During the movement, the touch-up paint nozzle 9.11 and the painting nozzle 9.12 will continuously spray paint to evenly cover the surface of the object with a layer of paint. The moving speed of the enameled wire 14 is related to the painting speed, which depends on the material of the enameled wire 14 and the type and parameters of the paint.

[0040] Both the touch-up paint recovery cover 9.21 and the paint application recovery cover 9.22 are spherical covers. The touch-up paint recovery cover 9.21 faces the touch-up paint nozzle 9.11. The enameled wire 14 near the touch-up paint nozzle 9.11 is located between the touch-up paint recovery cover 9.21 and the touch-up paint nozzle 9.11. The paint application recovery cover 9.22 faces the paint application nozzle 9.12. The enameled wire 14 near the paint application nozzle 9.12 is located between the paint application recovery cover 9.22 and the paint application nozzle 9.12.

[0041] The paint recovery cover 9.21 and the paint recovery cover 9.22 are connected by a combination pipe 9.2. The bottom of the combination pipe 9.2 is connected to the vacuum pump 10. The vacuum pump 10 is connected to the oil-water separator 11. The oil-water separator 11 is equipped with a pressure pump and is connected to the annular pipe 9.1 by a hose.

[0042] The annular pipe 9.1 serves as a conduit for the paint spraying head 9.12 and the touch-up paint spraying head 9.11 to supply the paint solution. The touch-up paint recovery hood 9.21 and the paint spraying head 9.22 are used to collect excess paint spray generated by the paint spraying head 9.12 and the touch-up paint spraying head 9.11 during the spraying process. When the paint spraying head 9.12 and the touch-up paint spraying head 9.11 are working, the generated paint spray is sucked in by the touch-up paint recovery hood 9.21 and the paint spraying head 9.22, and then processed by the oil-water separator 11 to separate the water and impurities in the paint mist, ensuring the quality of the recovered paint. By connecting to a special automatic paint mixing device, the paint is converted back into liquid paint and connected to the annular pipe 9.1, thus forming a cycle, improving the paint utilization efficiency and saving significant paint costs.

[0043] Meanwhile, the design of the touch-up paint recovery hood and the paint application recovery hood allows for the timely collection of paint mist generated during the spraying process, preventing pollution to the surrounding environment. The use of a combined pipe not only makes the connection between the two recovery hoods tighter but also effectively guides the paint mist to the vacuum pump, improving recovery efficiency.

[0044] As the core component of the entire recycling system, the vacuum pump's performance directly affects the recycling effect. Under the action of the vacuum pump, paint mist is rapidly drawn in and processed through the oil-water separator. The pressure pump ensures that the paint in the oil-water separator flows smoothly into the annular pipe, preparing it for the next spraying operation.

[0045] The entire recycling system uses flexible hose connections, which not only facilitates installation but also effectively reduces system vibration and noise. Furthermore, the hoses possess a degree of flexibility, allowing them to adapt to different working environments and improving the system's stability and reliability.

[0046] In summary, the paint recovery hood, paint recovery hood, combined pipe, vacuum pump, oil-water separator, and annular pipe together constitute a highly efficient and environmentally friendly paint recycling system, providing strong support for paint spraying operations.

[0047] The winding reel 6, the unwinding reel 12, and the take-up reel 13 are all located in the same plane, and enameled wire 14 is wound between the winding reel 6, the unwinding reel 12, and the take-up reel 13.

[0048] The bellows 3, on which the winding reel 6 is mounted, has a rotatable, openable transparent safety cover 4 on its side. The transparent design allows the user to observe the working status of the winding reel 6 at any time, enabling timely adjustments and preventing accidents. The safety cover 4 is made of high-quality materials, possessing excellent wear resistance, impact resistance, and scratch resistance, effectively protecting the winding reel 6 from external damage. Furthermore, it also has a certain degree of fire resistance, preventing fires and other accidents to some extent.

[0049] The rotating opening and closing design of the safety cover allows users to easily maintain and clean it. When cleaning or inspecting the winding reel is required, users can simply rotate the safety cover to open it without the need for additional tools or equipment. This design is not only convenient and quick, but also effectively avoids unnecessary damage during cleaning or inspection.

[0050] The beneficial effects of this embodiment are:

[0051] The enameling line painting equipment with recyclable paint liquid in this embodiment has advantages such as simple operation, good painting effect, high paint liquid utilization rate, and environmental protection and energy saving. It is suitable for enameling line painting operations in large-scale production. At the same time, its unique recycling design also enables the effective utilization of paint liquid, reduces production costs, and improves economic efficiency.

[0052] In addition to the above embodiments, within the scope disclosed in the claims and description of this utility model, the technical features or technical data of this utility model can be reselected and combined to form new embodiments, which should also be regarded as specific embodiments of this utility model and within the protection scope of this utility model.
