Abstract
Description
Technical Field
[0001] This utility model relates to the field of enameled aluminum wire production technology, and more specifically, to an enameling equipment for enameled aluminum wire. Background Technology
[0002] Enameled aluminum wire is an electrical wire formed by coating the surface of aluminum wire with one or more layers of insulating varnish. It mainly consists of two parts: an inner aluminum conductor with good conductivity, capable of transmitting current; and an outer insulating varnish layer, which insulates and protects the conductor, preventing current leakage and short circuits, while also improving the wire's corrosion resistance and heat resistance. The production of enameled aluminum wire involves drawing and annealing, followed by spraying 10 to 12 layers of insulating varnish onto the surface. This insulating varnish protects the equipment during normal operation while enhancing the durability of the aluminum wire.
[0003] Existing aluminum wire insulation varnish equipment often uses immersion in a varnish tank or spraying. This spraying method is prone to uneven coating. For example, the patent for an enameled wire coating device with publication number CN218333275U uses an upper and lower spraying method to coat the enameled aluminum wire. This spraying method is prone to causing the varnish layer on the side of the aluminum wire to be thin, which can easily lead to uneven overall coating. In addition, the air drying method uses a simple fan to dry, which has low drying efficiency and lengthens the production line, taking up space. Utility Model Content

Detailed Implementation
[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] Please apply. Figure 1 and Figure 4 This application provides an example of an enameled aluminum wire painting device, comprising: a base 10; a spraying mechanism, mounted on the base 10, having several annularly distributed nozzles 21 for painting the surface of the aluminum wire; and a drying device, including a drying chamber 31 mounted on one side of the spraying mechanism 20; the drying chamber 31 is a closed chamber with openings on both sides for the aluminum wire to pass through, the aluminum wire entering the chamber through one opening of the spraying mechanism 20 and exiting through the other opening; a drying element 32 for drying the insulating varnish on the surface of the aluminum wire is provided on the inner wall of the drying chamber 31; and a wire take-up element 33 for storing the aluminum wire to extend the drying time is also provided inside the drying chamber 31.
[0025] Understandably, the spraying mechanism 20 is a component that sprays insulating varnish onto the surface of the aluminum wire to cover and encapsulate it. For example, it could be an air spraying mechanism 20 or a high-pressure spraying mechanism 20, but it is not limited to these. The nozzle 21 is the outlet for the insulating varnish in the spraying mechanism 20. The arrangement of the nozzle 21 determines the uniformity of the insulating varnish on the aluminum wire surface after spraying. For example, it could be arranged on a ring around the aluminum wire, with all nozzles 21 connected to the same delivery pipe to ensure uniform varnish application. Alternatively, it could be positioned above and below the aluminum wire, with independently distributed delivery pipes, but it is not limited to these. The drying mechanism 30 is a component used to dry the insulating varnish on the aluminum wire surface in a timely manner to prevent it from falling off. For example, it could be an electrically heated drying device or a gas-fired heated drying device, but it is not limited to these. The drying chamber 31 is the place used to dry the aluminum wire. For example, it could be a square drying chamber 31 or a cylindrical drying chamber 31, but it is not limited to these. The enclosed enclosure maximizes the heat generated by the drying component 32, but it needs to have openings at both ends for the aluminum wire to enter and exit. For example, the drying chamber 31 could have openings on both sides, with one end near the spraying machine and the other end opposite the spraying mechanism 20. Alternatively, one end could be near the spraying mechanism 20, and the other end at the top or bottom of the drying chamber 31, etc., but this is not limited to these examples. The drying component 32 is the part that aligns with the aluminum wire and dries and solidifies the insulating varnish on the surface of the aluminum wire. For example, it could be a single heating element, or a combination of blowing and heating to dry the insulating varnish on the surface of the aluminum wire, etc., but this is not limited to these examples. The take-up component 33 is the part that extends the drying time inside the chamber by winding the wire, etc. For example, it could be a single take-up reel 331, or a set of multiple take-up reels 331, etc., but this is not limited to these examples.
[0026] As can be seen from the above, the surrounding nozzles 21 can coat the aluminum wire without any blind spots, ensuring the uniform coating of the insulating varnish layer on the surface of the aluminum wire to the greatest extent. At the same time, the drying chamber 31 is equipped with a take-up component 33 and a drying component 32. The drying component 32 dries the insulating varnish on the surface of the aluminum wire as quickly as possible to prevent the insulating varnish from peeling off. After drying, the aluminum wire is wound up by the take-up component 33 to extend the drying time, ensuring that the varnish surface is dried and saving processing space.
[0027] As is known, in some embodiments, please refer to Figure 4 The spraying mechanism 20 also has a hopper 22 located on one side of the base 10 for storing insulating varnish. The nozzles 21 are arranged at equal angles around the aluminum wire.
[0028] Understandably, the material bin 22 is a sealed cavity for storing insulating varnish. For example, it can be a square rigid metal box or a sealed leather insulating varnish bag, but it is not limited to these.
[0029] With this design, the material bin 22 can store a large amount of insulating varnish, avoiding the need for repeated refilling.
[0030] As is known, in some embodiments, please refer to Figure 4 The enameled aluminum wire painting equipment also includes a wire reel 40 disposed between the spraying mechanism 20 and the drying mechanism 30 and used to support the aluminum wire so that the aluminum wire can safely transition between the spraying mechanism 20 and the drying mechanism 30.
[0031] Understandably, the wire reel 40 is a component placed between the spraying mechanism 20 and the drying mechanism 30 to prevent the aluminum wire from falling off due to excessive weight. For example, it can be a wire guide wheel 333 or a wire frame, but it is not limited to these.
[0032] As is known, in some embodiments, please refer to Figure 2 and Figure 3 The drying unit 32 has an air outlet 321 located on the inner side of the box and opening towards the aluminum wire, and heaters 322 located at the top and bottom of the box for raising the internal temperature of the box and drying the insulating varnish on the surface of the aluminum wire.
[0033] Understandably, the air outlet 321 is a component used to blow cool air onto the aluminum wire to dry the insulating varnish. For example, it could be a single large air outlet 321 located inside the drying chamber 31, or multiple air outlets 321 arranged side-by-side and directed at the aluminum wire, but it is not limited to these. The heater 322 is a component that heats the air inside the chamber to dry the insulating varnish on the surface of the aluminum wire. For example, it could be an electric heater 322, a gas heater 322, etc., but it is not limited to these.
[0034] This configuration, through the cooperation of the air outlet 321 and the heater 322, enables the simultaneous drying of the insulating varnish on the surface of the aluminum wire, thus improving the drying efficiency.
[0035] As is known, in some embodiments, please refer to Figure 4 The take-up assembly 33 has at least one take-up reel 331 installed inside the housing and a drive 332 for rotating the take-up reel 331. The take-up assembly 33 also includes guide reels 333 disposed inside the housing and located on both sides of the take-up reel 331.
[0036] Understandably, the take-up reel 331 is a component that can temporarily store aluminum wire. For example, it can be a single take-up reel 331 or a group of multiple take-up reels 331, etc., but it is not limited to this. The driver 332 is a component used to drive the take-up reel 331 to rotate, thereby driving the take-up reel 331 to wind the aluminum wire. For example, it can be a motor or a press, etc., but it is not limited to this.
[0037] With this configuration, the take-up reel 331 can increase the drying time of aluminum wire, improve drying efficiency, and save production space.
[0038] As is known, in some embodiments, please refer to Figure 2 and Figure 4 The take-up reel 331 is provided with a guide groove 41 to prevent the aluminum wire from getting tangled and to allow the aluminum wire to pass around.
[0039] Understandably, aluminum wires are easily tangled when wound together on the same take-up reel. Therefore, a wire groove 41 is provided on the take-up reel 331 to prevent the aluminum wires from tangling. For example, a wire groove 41 can be carved into the surface of the take-up reel 331, or a partition can be spirally arranged on the surface of the take-up reel 331 to form a wire groove, etc., but not limited to these methods.
[0040] This design prevents the aluminum wires from getting tangled together.
[0041] As can be seen from the above, the aluminum wire is pulled into the spraying mechanism, passes through the center of the spraying mechanism, and extends from the wire reel to the opening of the drying box to enter the drying box. After the aluminum wire at the front end is dried, it passes through the wire guide reel and is led to the take-up reel. It is wound around the take-up reel a few times, and then the aluminum wire is guided to the take-up reel on the other side and exited from the opening on the other side. Then the painting equipment is turned on.
[0042] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
