Description

Technical Field

[0001] This utility model belongs to the field of copper wire processing, and in particular relates to a copper wire feeding machine. Background Technology

[0002] Copper wire is a type of metal wire made primarily of copper. It is typically processed through copper smelting, continuous casting, rolling, and drawing. Its core characteristics are high conductivity, good ductility, and strong resistance to chemical corrosion. Therefore, it is widely used in fields such as power transmission, electronic equipment, communication systems, and machinery manufacturing. It is one of the indispensable basic metal materials in modern industry and daily life. In the field of copper wire processing, traditional copper wire unwinding machines mostly adopt a passive unwinding mode, which relies on the tension of the downstream process to drive the rotation of the I-beam to release the copper wire. This method is prone to unstable unwinding speed due to fluctuations in the downstream tension, which in turn leads to abnormal copper wire tension. When the tension is too high, it will cause the copper wire to stretch and deform, and the wire diameter to narrow, affecting its conductivity and structural strength. When the tension is too low, the copper wire will loosen and stack, resulting in tangled mess or even breakage, causing the production line to stop. This method cannot meet the requirements of stability and automation in copper wire processing. Utility Model Content

The unwinding device is used to hold bundles of copper wire. One end of the copper wire extends along the periphery of the tension component and is connected in series to a downstream device of the tension component. The downstream device is capable of pulling the copper wire to move linearly, and the unwinding tension of the unwound copper wire is adjusted by the tension component.

[0005] Furthermore, the tension assembly includes a slide rail, a slider, a first roller, and a second roller. The first roller is rotatably mounted on the frame, the slide rail is fixedly mounted below the first roller, the slider is slidably connected to the periphery of the slide rail, the second roller is rotatably mounted on the slider, and copper wires are slidably connected to the periphery of the first roller and the second roller.

[0006] Furthermore, two photoelectric sensors are fixedly installed on the frame, and the two photoelectric sensors are arranged in parallel to each other. The recognition end of each photoelectric sensor is used to sense the presence of the slider.

[0007] Furthermore, the tension assembly also includes a fixed block, a support rod, a rotating block, and a torsion spring.

[0011] Furthermore, the unwinding device includes a support, a power roller, a driven roller, an I-beam wheel, and a rotating motor. The support is set at the starting position of the process.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2As shown, a copper wire unwinding machine includes an unwinding device 1 and a downstream unwinding frame 2. The unwinding frame 2 includes a frame body 21 and a tension assembly 22. The frame body 21 is located on one side of the unwinding device 1, and the tension assembly 22 is mounted on the frame body 21. The unwinding device 1 is used to hold bundles of copper wire 3. One end of the copper wire 3 extends along the periphery of the tension assembly 22 and is connected in series to a downstream device of the tension assembly 22. The downstream device can pull the copper wire 3 to move linearly, and the unwinding tension of the unwound copper wire 3 is adjusted by the tension assembly 22. The tension assembly 22 includes a slide rail 221, a slider 222, a first roller 223, and a second roller 224. A first roller 224 is rotatably mounted on the frame body 21. The roller 223 has a slide rail 221 fixedly installed below it. The slide rail 221 is slidably connected to the outer periphery of the slide rail 222. The second roller 224 is rotatably mounted on the slide rail 222. The outer periphery of the first roller 223 and the second roller 224 is rotatably connected to the outer periphery of the two rollers. The tension assembly 22 also includes a fixed block 225, a support rod 226, a rotating block 227 and a torsion spring. One side of the slide rail 222 is rotatably connected to one end of the support rod 226. The outer periphery of the support rod 226 is slidably connected to the rotating block 227. The outer periphery of the rotating block 227 is rotatably connected to the fixed block 225. A torsion spring is provided between the fixed block 225 and the rotating block 227. The fixed block 225 is fixedly installed on the rear side of the frame 21.

[0024] After the copper wire 3 enters the tension assembly 22 through the guide structure 23, it will sequentially wind around the first roller 223 fixed on the frame 21 and the second roller 224 on the slider 222, forming a winding path. When the tension of the copper wire 3 changes dynamically, it will directly drive the second roller 224 and the slider 222 to slide up and down along the slide rail 221. The upward sliding of the slider 222 will push the rotating block 227 to rotate around the fixed block 225 through the support rod 226. At this time, the torsion spring between the fixed block 225 and the rotating block 227 is compressed, generating a reverse... The elastic force counteracts excess tension, preventing the copper wire 3 from slipping off the second roller 224 or the first roller 223 due to loosening. After the copper wire 3 is unwound, the torsion spring automatically resets, and the slider 222 is pulled downward by the rotating block 227 and the support rod 226 to tighten the copper wire and prevent it from slack and stacking. The tension component 22 is set up to quickly respond to slight changes in the tension of the copper wire and realize real-time dynamic adjustment of the tension, avoiding the problem of the copper wire 3 breaking due to a sudden increase in tension or the copper wire becoming loose and tangled due to a sudden decrease in tension during the unwinding process.

[0025] like Figure 3As shown, two photoelectric sensors 211 are fixedly installed on the frame 21. The two photoelectric sensors 211 are arranged in parallel with each other. The recognition end of each photoelectric sensor 211 can sense the slider 222. The photoelectric sensor 211 is existing technology, and the model of the photoelectric sensor 211 is GTB6-N1231. The two photoelectric sensors 211 on the frame 21 will sense the position of the slider 222 in real time. When the slider 222 slides into the sensing range of either photoelectric sensor 211, the photoelectric sensor 211 will feed back a signal to the control system to further fine-tune the unwinding speed of the unwinding device 1 so that the tension of the copper wire 3 is always maintained in a stable range.

[0026] like Figure 3 The wire feeding frame 2 also includes an inlet structure 23 and an outlet structure 24. The inlet structure 23 is used to determine the path of the copper wire 3 entering the tension assembly 22, and the outlet structure 24 is used to determine the path of the copper wire 3 exiting the tension assembly 22. The inlet structure 23 includes a roller frame 231 and two inlet rollers 232. The two inlet rollers 232 are rotatably arranged inside the roller frame 231 and are parallel to each other. The outer periphery of each inlet roller 232 is rolled and connected to one side of the copper wire 3. The outlet structure 24 includes two third rollers 241. Both third rollers 241 are rotatably arranged on the frame 21, and the outer periphery of each third roller 241 is rolled and connected to one side of the copper wire 3. The copper wire 3 exits from the two parallel and... The guide rollers 232, which are rotatably arranged within the roller frame 231, pass through each other. Since the periphery of each guide roller 232 is rolledly connected to one side of the copper wire 3, when the copper wire 3 moves along the unwinding direction, it will drive the two guide rollers 232 to rotate synchronously, thus preventing the copper wire 3 from shifting laterally before entering the tension adjustment stage. When the copper wire 3 comes out of the tension assembly 22, it drives the two third rollers 241 to rotate, which can limit the feeding path of the copper wire 3. The guide structure 23 can limit the path of the copper wire 3 entering the tension assembly 22, and the output structure 24 can limit the path of the copper wire 3 exiting the tension assembly 22. This solves the problem that the copper wire 3 is prone to loosening due to the deviation of the conveying direction and the instability of the path during the traditional unwinding process.

[0027] like Figure 4 and Figure 5As shown, the unwinding device 1 includes a support 11, a power roller 12, a driven roller 13, an I-beam 14, and a rotary motor 15. The support 11 is set at the starting position of the process. The power roller 12 and the driven roller 13 are rotatably arranged inside the support 11. The power roller 12 and the driven roller 13 are arranged parallel to each other. The outer periphery of the two end discs of the I-beam 14 are rolledly connected to the outer periphery of the power roller 12 and the driven roller 13. Copper wire 3 is sleeved around the outer periphery of the middle cylinder of the I-beam 14. The rotary motor 15 is fixedly installed on one side of the support 11. The output shaft of the rotary motor 15 is fixedly connected to one end of the power roller 12. Two limiting wheels 131 are fixedly sleeved around the outer periphery of the driven roller 13. The outer periphery of each limiting wheel 131 is rolledly connected to the outer periphery of the two end discs of the I-beam 14. The rotary motor 15 is existing technology, and the model of the rotary motor 15 is 49TYD-500-1. The I-beam 14 with bundles of copper wire 3 sleeved is placed on the support 11. Inside, the outer edges of the two end discs of the I-beam 14 roll in contact with the outer edges of the power roller 12 and the driven roller 13, respectively. At the same time, the two limiting wheels 131 on the outer edge of the driven roller 13 respectively abut against the sides of the two end discs of the I-beam 14, forming a lateral limit on the I-beam 14. The rotating motor 15 fixed on one side of the bracket 11 is started, and its output shaft drives the power roller 12 to rotate. The power roller 12 drives the I-beam 14 to rotate synchronously through the friction between the power roller 12 and the disc of the I-beam 14. The driven roller 13 rotates passively with the rotation of the I-beam 14, assisting in maintaining the stability of the I-beam 14. As the I-beam 14 rotates, the bundled copper wire 3 sleeved on the outer edge of its middle cylinder is gradually released. The released copper wire 3 is conveyed along the preset direction to the wire release frame 2 on one side. An unwinding device 1 is provided, which can unwind the bundled copper wire 3 into a single strand of copper wire 3, and can also facilitate the replacement of the I-beam 14 wound with copper wire 3 of different sizes, thereby improving work efficiency.

[0028] The working process of a copper wire feeding machine: The rotating motor 15 of the unwinding device 1 is started, and its output shaft drives the power roller 12 to rotate. The power roller 12 drives the I-beam 14 to rotate through friction. The driven roller 13 rotates passively with the I-beam 14, and the limiting wheel 131 on the driven roller 13 restricts the lateral displacement of the I-beam 14, thereby realizing the unwinding of the copper wire 3. The unwound copper wire 3 first enters the guide structure 23, passes through the two guide rollers 232 in the roller frame 231 and enters the tension assembly 22. The copper wire 3 winds around the first roller 223 on the frame 21 and the second roller 224 on the slider 222. When the tension changes, it drives the slider 222 to slide along the slide rail 221. The slider 222 pulls the rotating block 227 to rotate around the fixed block 225 through the support rod 226. The torsion spring cooperates to buffer and adjust the tension. Finally, the copper wire 3 is guided by the two third rollers 241 of the guide structure 24 and pulled into the downstream process by the tension generated by the downstream process.

[0029] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
