Description

Technical Field

[0001] This utility model relates to the field of wire wrapping technology, specifically a wire wrapping machine for transposition. Background Technology

[0002] The transposed conductor wrapping machine is a specialized piece of equipment used for automated wrapping and insulation treatment of transposed conductors. It is widely used in high-voltage power equipment such as transformers and reactors, and reduces eddy current loss and circulating current loss through conductor transposition design.

[0003] A search revealed a utility model patent with Chinese patent publication number CN219370689U, which discloses a transposition wire wrapping machine. This machine uses a limiting device to position the transposition wire at the center of the wrapping disc. It includes a wrapping disc with a channel in the center for the transposition wire to pass through. A wrapping pulley is connected to the wrapping disc, and insulating tape is wound around the pulley. Limiting mechanism one and limiting mechanism two are respectively located at the front and rear ends of the wrapping disc.

[0004] The above-mentioned device achieves wrapping by installing the wrapping tape on the wrapping pulley and then driving the wrapping reel to revolve around the conductor. However, the connection method is relatively simple and the rotation of the reel is relatively easy, which inevitably leads to insufficient wrapping force of the wrapping tape. There may be gaps between the wrapping tape and the conductor, which will affect the insulation performance of the conductor. Utility Model Content

[0005] The purpose of this invention is to provide a transposition wire wrapping machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transposition wire wrapping machine, comprising a support frame, wherein an installation ring is rotatably connected inside the support frame via a bearing, and two equally spaced friction components are installed outside the installation ring. Each friction component includes a hinge seat fixedly connected to one outer wall of the installation ring, an installation plate hinged inside the hinge seat, a limit frame fixedly connected to one outer wall of the installation plate, an installation seat slidably sleeved outside the limit frame, a vertically arranged rubber sheet adhered inside the installation seat, and a horizontally arranged lead screw rotatably connected inside the limit frame, the lead screw being threaded into the installation seat.

[0007] The resistance encountered during the rotation of the mounting shaft can be adjusted as needed, ensuring that the wrapping tape between the mounting shaft and the conductor remains taut. This effectively prevents gaps and helps guarantee the insulation performance of the conductor. During the wrapping process, as the wrapping tape on the reel is continuously released, the length of the wrapping tape between the reel and the conductor gradually shortens, and the reel begins to rotate and unwind under the traction of the conductor. Because the rubber sheet is tightly fitted to the outer wall of the mounting shaft, the frictional resistance of the rubber sheet during the rotation of the mounting shaft causes the wrapping tape to gradually tighten and adhere tightly to the surface of the conductor, forming a stable wrapping layer.

[0008] As a further preferred embodiment of this technical solution, an adjustment assembly is installed on the outside of the mounting plate. The adjustment assembly includes a mounting shaft that is threadedly connected to one side of the mounting plate. A limit strip is provided on the outside of the mounting shaft. A screw is threadedly connected inside the limit strip. The diameter of the end of the screw is larger than the diameter of the mounting shaft.

[0009] As a further preferred embodiment of this technical solution, an extension plate is fixedly connected to the outer wall of one end of the rotating shaft of the mounting plate, and two screw rods are threadedly connected inside the extension plate. A number of limiting holes adapted to the two screw rods are opened on the outer wall of one end of the hinge seat.

[0010] Different specifications of cables, wires, or pipes have different diameters, so the required wrapping inclination also varies. The two screws can be rotated counterclockwise. When they are disengaged from the limiting holes of the hinge seat, the rotation of the extension plate and the mounting plate will no longer be restricted. Therefore, the inclination angle of the mounting shaft can be adjusted at will. After the adjustment is completed, the screws are driven into the corresponding limiting holes, and the position of the mounting plate will be fixed again.

[0011] As a further preferred embodiment of this technical solution, a drive assembly is installed between the support frame and the mounting ring. The drive assembly includes a gear ring, which is fixedly sleeved on the outside of the mounting ring. A motor is fixedly installed on one side of the outer wall of the support frame, and a gear is coaxially fixed at the output end of the motor, which meshes with the gear ring.

[0012] As a further preferred embodiment of this technical solution, a connection hole is provided at each of the four corners of the bottom outer wall of the support frame.

[0013] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread of the lead screw is smaller than the equivalent friction angle.

[0014] As a further preferred embodiment of this technical solution, the mounting ring is made of aluminum alloy.

[0015] This utility model provides a transposed wire wrapping machine, which has the following beneficial effects:

[0016] (1) By setting a friction component, this utility model can adjust the resistance encountered by the mounting shaft during rotation as needed, so that the wrapping tape between the mounting shaft and the conductor can remain taut, effectively avoiding gaps and ensuring the insulation performance of the conductor. During the wrapping operation, as the wrapping tape on the reel is continuously released, the length of the wrapping tape between the reel and the conductor gradually shortens, and the reel begins to rotate and unwind under the traction of the conductor. Because the rubber sheet is tightly attached to the outer wall of the mounting shaft, the mounting shaft is subjected to the frictional resistance of the rubber sheet when rotating, causing the wrapping tape to gradually tighten and adhere tightly to the surface of the conductor, forming a stable wrapping layer.

[0017] (2) By setting an adjustment component, the diameter of cables, wires or pipes of different specifications are different, so the required wrapping inclination is also different. The two screws can be rotated counterclockwise. When the two screws are disengaged from the limiting hole of the hinge seat, the rotation of the extension plate and the mounting plate will no longer be restricted. Therefore, the inclination angle of the mounting shaft can also be adjusted at will. After the adjustment is completed, the screws are driven into the limiting hole at the corresponding position, and the position of the mounting plate will be fixed again. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 3 and Figure 4As shown, in this embodiment, the transposition wire wrapping machine includes a support frame 1. Inside the support frame 1, a mounting ring 2 is rotatably connected via a bearing. Two equally spaced friction components 4 are mounted on the outside of the mounting ring 2. Each friction component 4 includes a hinge seat 401 fixedly connected to one side of the outer wall of the mounting ring 2. Inside the hinge seat 401, a mounting plate 402 is hinged. One side of the outer wall of the mounting plate 402 is fixedly connected to a limit frame 403. A mounting seat 404 is slidably sleeved on the outside of the limit frame 403. A vertically arranged rubber sheet 406 is adhered inside the mounting seat 404. A horizontally arranged lead screw 405 is rotatably connected inside the limit frame 403. The lead screw 405 is threadedly connected inside the mounting seat 404.

[0025] During the wrapping operation, as the wrapping tape on the reel is continuously released, the length of the wrapping tape between the reel and the conductor gradually shortens, and the reel begins to rotate and unwind under the traction of the conductor. Because the rubber sheet 406 is tightly attached to the outer wall of the mounting shaft 501, the mounting shaft 501 is subjected to frictional resistance from the rubber sheet 406 when it rotates, causing the wrapping tape to gradually tighten and adhere tightly to the surface of the conductor, forming a stable wrapping layer. If it is necessary to increase the tension, the screw 405 is rotated by the handle. The screw 405 drives the mounting seat 404 to move closer to the mounting shaft 501 along the limit frame 403. The rubber sheet 406 exerts greater pressure on the mounting shaft 501 and has a larger contact area, which makes the resistance to the rotation of the mounting shaft 501 greater.

[0026] like Figure 2 and Figure 3 As shown, an adjustment assembly 5 is installed on the outside of the mounting plate 402. The adjustment assembly 5 includes a mounting shaft 501 connected to one side of the mounting plate 402 by a thread. A limit strip 502 is provided on the outside of the mounting shaft 501. A screw 503 is threadedly connected inside the limit strip 502. The diameter of the end of the screw 503 is larger than the diameter of the mounting shaft 501.

[0027] An extension plate 504 is fixedly connected to the outer wall of one end of the rotating shaft of the mounting plate 402. Two screw rods 505 are threadedly connected inside the extension plate 504. Several limiting holes 506 adapted to the two screw rods 505 are opened on the outer wall of one end of the hinge seat 401.

[0028] Different specifications of cables, wires, or pipes have different diameters, so the required wrapping inclination also varies. The two screws 505 can be rotated counterclockwise. When they are disengaged from the limiting hole 506 of the hinge seat 401, the rotation of the extension plate 504 and the mounting plate 402 will no longer be restricted. Therefore, the inclination angle of the mounting shaft 501 can be adjusted at will. After the adjustment is completed, the screws 505 are driven into the corresponding limiting hole 506, and the position of the mounting plate 402 will be fixed again.

[0029] like Figure 1 and Figure 2As shown, a drive assembly 6 is installed between the support frame 1 and the mounting ring 2. The drive assembly 6 includes a gear ring 601, which is fixedly sleeved on the outside of the mounting ring 2. A motor 603 is fixedly installed on one side of the outer wall of the support frame 1. A gear 602 is coaxially fixed at the output end of the motor 603, and the gear 602 meshes with the gear ring 601.

[0030] The motor 603 installed on the outside of the support frame 1 is started. The motor 603 drives the gear 602 to start rotating. The gear 602 drives the gear ring 601 to rotate through meshing. The gear ring 601 drives the mounting ring 2 to rotate inside the support frame 1. The mounting shaft 501 and the wrapping tape reel installed on the outside of the mounting ring 2 will revolve around the conductor. The wrapping tape can then wrap the surface of the conductor.

[0031] like Figure 1 and Figure 2 As shown, each of the four corners of the bottom outer wall of the support frame 1 has a connecting hole 3, through which the connector can pass to connect with the external structure.

[0032] like Figure 4 As shown, the thread helix angle of the external thread of the lead screw 405 is less than the equivalent friction angle, giving it a self-locking property and ensuring that the position of the mounting base 404 connected to it will not change arbitrarily.

[0033] like Figure 1 and Figure 2 As shown, the mounting ring 2 is made of aluminum alloy, which can ensure its strength while also reducing the load on the motor 603.

[0034] This utility model provides a transposed wire wrapping machine, the specific working principle of which is as follows:

[0035] When the device is working, the wire is transmitted through the internal through hole of the mounting ring 2 by the external transmission device, and the motor 603 installed on the outside of the support frame 1 is started. The motor 603 drives the gear 602 to start rotating. The gear 602 drives the gear ring 601 to rotate through meshing. The gear ring 601 drives the mounting ring 2 to rotate inside the support frame 1. The mounting shaft 501 and the wrapping tape reel installed on the outside of the mounting ring 2 will revolve around the wire. The wrapping tape can then wrap the surface of the wire. During the wrapping operation, as the wrapping tape on the reel is continuously released, the length of the wrapping tape between the reel and the wire gradually shortens. The reel begins to rotate and unwind under the traction of the wire. Because the rubber sheet 406 is tightly attached to the outer wall of the mounting shaft 501, the mounting shaft 501 is subjected to frictional resistance from the rubber sheet 406 when it rotates, causing the wrapping tape to gradually tighten and adhere tightly to the surface of the conductor, forming a stable wrapping layer. If it is necessary to increase the tightness, the screw 405 is rotated by the handle. The screw 405 drives the mounting seat 404 to move closer to the mounting shaft 501 along the limit frame 403. The rubber sheet 406 exerts greater pressure on the mounting shaft 501 and has a larger contact area, which makes the resistance to the rotation of the mounting shaft 501 greater. Different specifications of cables, wires, or pipes have different diameters, so the required wrapping inclination also varies. The two screws 505 can be rotated counterclockwise. When they are disengaged from the limiting hole 506 of the hinge seat 401, the rotation of the extension plate 504 and the mounting plate 402 will no longer be restricted. Therefore, the inclination angle of the mounting shaft 501 can be adjusted at will. After the adjustment is completed, the screws 505 are driven into the corresponding limiting hole 506, and the position of the mounting plate 402 will be fixed again.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
