The upper and lower tension fixed wheels are located on the upper and lower sides of the brake wheel, spaced apart from it. The brake wheel is spaced apart from the tension sliding wheel. The two ends of the tension belt are respectively sleeved on the upper and lower tension fixed wheels. The tension sliding wheel is located inside the tension belt and abuts against the side of the tension belt away from the first channel.

[0024] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0025] like Figures 1-5 As shown, this application provides a wire feeding device including a wire feeding frame 1, a main column 2, an upper support arm 3, and a wheel and axle assembly 4. The wire feeding frame 1 is located on one side of the main column 2, and the upper support arm 3 is located above the wire feeding frame 1 and connected to the main column 2. The wheel and axle assembly 4 is disposed on the upper support arm 3. The wheel and axle assembly 4 includes a support plate 41, a pressure roller 42, a guide roller 43, a brake roller 44, and a tension assembly. The support plate 41 is disposed on the upper support arm 3, and one side of the support plate 41 is provided with the pressure roller 42, the guide roller 43, the brake roller 44, and the tension assembly. The end of the upper support arm 3 near the wire feeding frame 1 includes a first channel for the winding wire to pass through. The tension assembly is disposed on the side of the brake roller 44 away from the first channel, and the guide roller 43 and the pressure roller 42 are disposed on the side of the brake roller 44 near the first channel. The guide roller 43 is located above the pressure roller 42. The wire feeding frame 1 contains the winding wire. Preferably, the winding wire can be a metal conductor, such as copper wire, iron wire, or aluminum wire. The upper support arm 3 and the pressure roller 42 form a second channel for the winding wire to pass through, the brake roller 44 and the tension assembly form a third channel for the winding wire to pass through, and the brake roller 44 and the lead-out guide roller 43 form a fourth channel for the winding wire to pass through. The winding wire passes through the first channel, the second channel, the third channel and the fourth channel in sequence.

[0026] Preferred, such as Figure 1 As shown, the upper support arm 3 is provided with a wire guide wheel 31. The wire guide wheel 31 is located on the side of the pressure wheel 42 near the first channel. The second channel is formed between the wire guide wheel 31 and the pressure wheel 42. After the winding wire passes through the top of the wire guide wheel 31, it passes through the bottom of the pressure wheel 42. The wire guide wheel 31 is provided to help to straighten the winding wire and prevent the winding wire from deviating from the track of the pressure wheel 42 due to its own deformation curvature and coming off the bottom of the pressure wheel 42.

[0027] in, Figure 2 This is a front view of the wire-laying device of this application. Figure 3 and Figure 4 These are left and right views of the wire-feeding device of this application. Figure 5 This is a top view of the wire-laying device of this application.

[0028] The wire feeding device of this application is provided with a main column 2, and the wheel and axle assembly 4 is provided on the top of the main column 2. The wire feeding frame 1 is located on one side of the main column 2, which can lead the winding wire in the wire feeding frame 1 to a higher position. This solves the defect of traditional wire feeding devices that can only operate on the same floor. It can be applied to application scenarios with limited space and small area, improve the utilization rate of space, and further save production costs. At the same time, the wheel and axle assembly 4 includes a tension assembly, which cooperates with the brake wheel 44. During the production process, the tension of the winding wire can be adjusted to prevent the winding wire from breaking due to excessive tension when accelerating the wire feeding; and to prevent the winding wire from being too loosely wound due to insufficient tension when decelerating the wire feeding, which would affect the production quality.

[0029] Preferred, such as Figure 1 and Figure 3 As shown, the tension assembly includes an upper tension fixed wheel 451, a lower tension fixed wheel 452, a tension sliding wheel 454, and a tension belt 455. The upper tension fixed wheel 451 and the lower tension fixed wheel 452 are located on the upper and lower sides of the brake wheel 44, and are spaced apart from the brake wheel 44. The tension sliding wheel 454 is located on the side of the brake wheel 44 away from the first channel, and is spaced apart from the brake wheel 44. The tension belt 455 connects the upper tension fixed wheel 451, the lower tension fixed wheel 452, the brake wheel 44, and the tension sliding wheel 454. The tension belt 455 is respectively fitted onto the upper tension fixed wheel 451 and the lower tension fixed wheel 452. The tension sliding wheel 454 is located inside the tension belt 455 and abuts against the side of the tension belt 455 away from the first channel, so that the side away from the first channel is recessed to the right at a certain angle. The brake wheel 44 is located outside the tension belt 455 and abuts against the side of the tension belt 455 near the first channel, so that the side near the first channel is recessed to the right at a certain angle. The third channel is formed between the brake wheel 44 and the side of the tension belt 455 near the first channel.

[0030] Furthermore, such as Figure 3 As shown, the tension assembly also includes a tension sliding block 456, which is connected to the tension sliding wheel 454. The tension of the tension belt 455 is changed by the change in the distance between the tension sliding block 456 and the tension sliding wheel 454.

[0031] Preferably, the tension sliding block 456 is fixedly disposed, the tension sliding wheel 454 is slidably disposed, and an elastic element is disposed between the tension sliding block 456 and the tension sliding wheel 454. The elastic element may be, but is not limited to, a tension spring, a torsion spring, or a compression spring. In this application, a compression spring is preferred. In use, the end of the winding thread passes upward sequentially through the bottom of the pressure wheel 42, between the brake wheel 44 and the side of the tension belt 455 near the first channel, and the bottom of the lead-out guide wheel 43, so that the end of the winding thread extends upward. The brake wheel 44 and the side of the tension belt 455 near the first channel clamp and squeeze the winding thread.

[0032] During the production process, the movement of the tension sliding wheel 454 changes the distance between the tension sliding wheel 454 and the tension sliding block 456, compressing or releasing the elastic element. This causes the tension of the tension belt 455 to change, and the squeezing force of the brake wheel 44 and the tension belt 455 on the winding thread also changes, thereby altering the tension of the winding thread during the production process.

[0033] For example, when the winding speed increases, the distance between the tension sliding wheel 454 and the tension sliding block 456 decreases, compressing the elastic element to reduce the tension of the tension belt 455. This, in turn, reduces the squeezing force of the tension belt 455 and the brake wheel 44 on the winding thread, preventing the winding thread from breaking due to excessive tension. When the winding speed decreases, the elastic element begins to release energy, increasing the distance between the tension sliding wheel 454 and the tension sliding block 456. This increases the tension of the tension belt 455, further increasing the squeezing force of the tension belt 455 and the brake wheel 44 on the winding thread, preventing excessive excess winding due to insufficient tension, which would affect production quality. As the winding speed changes, this application can automatically adjust the tension of the winding thread, improving production efficiency and quality.

[0034] Furthermore, such as Figure 1 As shown, the upper support arm 3 is perpendicular to the main column 2.

[0035] Preferred, such as Figure 1 As shown, the upper support arm 3 is provided with a first through hole 32. The first channel includes the first through hole 32. The winding line extends out from the first through hole 32 and connects to the bottom of the pressure wheel 42. The first through hole 32 is used to limit the winding line and prevent the winding line from deviating and swinging, and from coming off the bottom of the pressure wheel 42.

[0036] Preferably, in other embodiments, the first channel is a first notch opened at one end of the upper support arm 3 near the wire feeding frame 1, and the winding line extends out from the first notch and connects to the bottom of the pressure roller 42. The first notch can limit the winding line and prevent the winding line from deviating from the predetermined track.

[0037] Preferred, such as Figure 5As shown, a bearing 33 is installed inside the first through hole 32, and the winding wire passes through the central hole of the bearing 33. Furthermore, the bearing 33 is placed horizontally, and the through direction of the central hole of the bearing 33 (the height direction of the main column 2) is the same as the through direction of the first through hole 32. Since the winding wire is coiled in a loop on the coil, it will rotate within the wire feeding frame 1 during the wire feeding process, resulting in rotational energy release. After the bearing 33 is installed inside the first through hole 32, the winding wire extends out from inside the bearing 33, following the rotation direction of the winding wire. This reduces the resistance of the winding wire within the first through hole 32, making the operation smoother.

[0038] Preferably, in other embodiments, a limiting plate perpendicular to the upper support arm 3 is provided on the side of the upper support arm 3 near the first channel. The limiting plate includes a second through hole, and the first channel includes the second through hole. The winding wire extends from the second through hole to limit the swing of the winding wire. Preferably, a bearing 33 is provided in the second through hole. The through direction of the central hole of the bearing 33 (the length direction of the upper support arm 3) is the same as the through direction of the second through hole. The winding wire extends from the central hole of the bearing 33, which can reduce the resistance in the second through hole.

[0039] Preferred, such as Figures 1-4 As shown, the first through hole 32 connects to the horn component 34, and the winding wire extends from the horn component 34 into the first through hole 32. The smallest diameter end of the horn component 34 is installed in the first through hole 32, and the largest diameter end of the horn component 34 faces the wire feeding frame 1. The first channel includes the horn component 34 and the first through hole 32. The structure and installation method of the horn component 34 facilitate the winding wire to extend into the first through hole 32 and gather the winding wire.

[0040] In this embodiment, the smallest diameter end of the horn member 34 extends into the central hole of the bearing 33.

[0041] Preferred, such as Figures 1-4 As shown, the wire feeding device also includes a first lower support arm 5, located between the upper support arm 3 and the wire feeding frame 1. One end of the first lower support arm 5 is connected to the main column 2, and the other end is connected to a first wire control ring 51. The first wire control ring 51 is opposite to the horn member 34, and the through direction of the first wire control ring 51 is the same as that of the horn member 34. The diameter of the first wire control ring 51 is larger than the maximum diameter of the horn member 34. The first wire control ring 51 is used to restrain the swinging winding wire. Since the first lower support arm 5 is closer to the wire feeding frame 1 than the upper support arm 3, the swinging of the winding wire is more intense. Therefore, the diameter of the first wire control ring 51 is larger than the maximum diameter of the horn member 34. The winding wire passes through the first wire control ring 51, the maximum diameter of the horn member 34, and the minimum diameter of the horn member 34, layer by layer limiting the swing amplitude of the winding wire, so that the winding wire enters the wheel axle assembly 4 stably. The first wire control ring 51 is preferably made of metal, such as iron or copper.

[0042] Furthermore, a second lower support arm is also included between the first lower support arm 5 and the wire feeding frame 1. One end of the second lower support arm is connected to the main column 2, and the other end is connected to the second wire control ring. The diameter of the second wire control ring is larger than the diameter of the first wire control ring 51.

[0043] Furthermore, a third lower support arm can be set between the second lower support arm and the wire feeding frame 1. One end of the third lower support arm is connected to a third control ring. The diameter of the third control ring is larger than that of the second control ring. Similarly, as the height of the main column increases, multiple lower support arms can be set to further enhance the gathering effect of the winding line and prevent the winding line from swinging too much.

[0044] Furthermore, the first lower support arm 5, the second lower support arm, and the third lower support arm are perpendicular to the main column 2.

[0045] Preferably, the upper support arm 3, the first lower support arm 5, the second lower support arm, and the third lower support arm are parallel to each other, and the middle part of the wire feeding frame 1, the middle part of the first wire control ring 51 and / or the second first wire control ring 51 and / or the third wire control ring, and the through direction of the horn member 34 are perpendicular to the same straight line.

[0046] Preferred, such as Figures 1-3 As shown, the wire feeding device also includes a ladder 6, which is fixed on the main column 2. The length direction of the ladder 6 is consistent with the height direction of the main column 2. The ladder 6 is set to facilitate pulling the end of the winding wire into the wheel axle assembly 4, and also facilitates the maintenance of the wire feeding device.

[0047] Furthermore, such as Figure 1 As shown, the ladder 6 is spaced apart from the wire-laying frame 1, and preferably the ladder 6 is located on the side of the main column 2 away from the wire-laying frame 1.

[0048] Preferred, such as Figure 1 As shown, the wire feeding device also includes a wire feeding frame base 7, which is located at the bottom of the main column 2 and provides support for the wire feeding device.

[0049] Furthermore, the cable tray base 7 has a fixing hole, which can be used to install and fix the cable tray to the bottom surface by passing a fixing screw through the fixing hole.

[0050] Furthermore, the cable laying frame base 7 includes wheels to facilitate the movement of the cable laying device.

[0051] Furthermore, the bottom of the wire laying frame 1 is also provided with wheels.

[0052] Preferably, the winding wire is copper wire, which is a single solid annealed soft copper conductor with a smooth surface. The main product diameters include, but are not limited to, 1.13mm, 1.78mm, 2.26mm and 2.76mm.

[0053] Preferably, the pressure roller 42, the infeed guide roller 31, the upper tension fixed roller 451, the lower tension fixed roller 452, and the tension sliding roller 454 have the same radius, and the radius of the pressure roller 42, the infeed guide roller 31, the upper tension fixed roller 451, the lower tension fixed roller 452, and the tension sliding roller 454 is smaller than the radius of the outlet guide roller 43, and the radius of the outlet guide roller 43 is smaller than the radius of the brake roller 44. For example, the radius of the brake roller 44 is 150mm, the radius of the pressure roller 42, the infeed guide roller 31, the upper tension fixed roller 451, the lower tension fixed roller 452, and the tension sliding roller 454 are all 50mm, and the radius of the outlet guide roller 43 is 100mm. Of course, the pressure roller 42, the infeed guide roller 31, the upper tension fixed roller 451, the lower tension fixed roller 452, the tension sliding roller 454, the brake roller 44, and the outlet guide roller 43 can also be other sizes.

[0054] Furthermore, the diameter of the first through hole 32 can be 50mm, and the depth of the first through hole 32 or the thickness of the upper support arm 3 can be 100mm.

[0055] Preferred, such as Figures 1-4 As shown, the pay-off frame 1 includes an outer frame and a fixing post. The fixing post is located at the center of the outer frame and is used to place the winding coil. The outer frame is preferably a cage mesh structure, which can reduce the weight of the pay-off frame 1.

[0056] Preferably, the wire feeding device of this application can be used to produce national standard BV, ZR-BV, ZA-BV, ZB-BV, ZC-BV, and BYJ1mm wires. 2 1.5mm 2 2.5mm 2 4mm 2 6mm 2 The production line for single copper conductors is laid out.

[0057] Furthermore, the wire-laying device of this application can be used for wire-laying operations in the production of single copper conductors conforming to American, Australian, and European standards.

[0058] Furthermore, the wire feeding device of this application can be used for continuous wire feeding of other metallic materials or hard non-metallic materials such as iron wire, aluminum wire, copper-clad aluminum, and copper-clad steel.

[0059] Furthermore, the wire feeding device of this application can be used in wire drawing machines, wire cutting machines, and other equipment that require continuous wire feeding.

[0060] Furthermore, the wire-laying device of this application can be used for laying out finished wires with a diameter of 5.0 mm or less.

[0061] Furthermore, the multiple wire feeding devices of this application can be used in conjunction with a 7-strand stranding machine to form a 1+6 stranding structure.

[0062] When processing electrical wires, the weight of the metal conductors makes it inconvenient to work on high floors. Therefore, this application allows the wires to be placed on the first floor, with wiring processing done on the second floor. The metal conductors are then extruded. This application can be used with 50, 65, 70, 80, and 90 extruders. The end of the winding wire in the first wire feeding frame can be cold-pressed to the beginning of the next frame's winding wire, enabling continuous production without stopping the machine. This greatly reduces the scrap of defective products caused by intermediate wire changing reels, eliminates the need for material turnover, saves time, improves production efficiency, and reduces labor intensity.
