Description
Technical Field
[0001] This utility model relates to the technical field of copper stranded wire production equipment, and in particular to a multi-strand copper stranded wire production and unwinding device. Background Technology
[0002] In the production of multi-strand copper wire, the unwinding device is an indispensable and crucial piece of equipment. It undertakes the core task of orderly releasing the coiled single-strand copper wires and is the starting point of the entire production process. By precisely controlling the release speed and tension of the copper wires, the unwinding device ensures that each copper wire can enter the subsequent stranding process in a stable state, laying the foundation for the formation of multi-strand copper wire. At the same time, an efficient and stable unwinding device can ensure the continuity of the production process and avoid production interruptions caused by unwinding problems. It plays a key role in improving production efficiency and reducing production costs, and is an important guarantee for achieving high-quality, large-scale production of multi-strand copper wire.
[0003] Traditional wire feeding devices typically employ simple wire feeding frames. During the feeding process, it is difficult to maintain consistent tension among the various strands of copper wire, leading to tangling and knotting. This not only affects the production quality of the copper strands but also reduces production efficiency. Furthermore, traditional wire feeding devices cannot flexibly adjust the feeding speed and tension according to production needs, making it difficult to meet the production requirements of multi-strand copper wires of different specifications. In addition, existing wire feeding devices lack effective guiding mechanisms during the feeding process, making it easy for the copper strands to deviate during transport, resulting in deviations in subsequent stranding processes. Therefore, we propose a multi-strand copper wire production wire feeding device. Utility Model Content
[0004] The purpose of this invention is to provide a multi-strand copper wire production unwinding device to solve the problems of traditional unwinding devices, which typically use simple unwinding frames. During the unwinding process, it is difficult to maintain consistent tension among the various strands of copper wire, leading to tangling and knotting. This not only affects the production quality of the copper wire but also reduces production efficiency. Furthermore, traditional unwinding devices cannot flexibly adjust the unwinding speed and tension according to production needs, making it difficult to meet the production requirements of multi-strand copper wires of different specifications. In addition, existing unwinding devices lack an effective guiding mechanism during the unwinding process, making it easy for the copper wire to deviate during transport, resulting in deviations in subsequent stranding processes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-strand copper wire production and feeding device, comprising a base, a base feeding assembly, a tension adjusting assembly, and a guiding assembly. The feeding assembly is used to place and feed out the copper stranded wire, the tension adjusting assembly is used to adjust the tension of the copper stranded wire, and the guiding assembly is used to guide the copper stranded wire. The feeding assembly includes a bracket, a reinforcing rib, a motor, a rotating shaft, and a feeding reel. The bracket is fixed to the rear end of the base surface, the reinforcing rib is fixedly disposed between the bracket and the base, and the motor is mounted on the outer surface of the right side of the bracket.
[0006] As a preferred embodiment, the rotating shaft is connected to the output shaft of the motor and rotatably connected inside the bracket. Multiple sets of wire feeding reels are provided and sleeved on the rotating shaft, and the multiple sets of wire feeding reels are detachably connected to the rotating shaft.
[0007] As a preferred embodiment, the guide assembly includes a U-shaped fixing frame, a U-shaped mounting plate, and a guide sleeve. The U-shaped fixing frame is fixed on the front surface of the base, the U-shaped mounting plate is fixedly mounted on the U-shaped fixing frame, and the guide sleeve is disposed on the U-shaped mounting plate, through which copper stranded wires can pass.
[0008] As a preferred embodiment, the guide sleeve is provided in multiple sets, which is the same as the number of wire reels. The inner wall of the guide sleeve is provided with a wear-resistant layer to reduce wear between the copper stranded wire and the guide sleeve.
[0009] As a preferred embodiment, the tension adjustment assembly includes a limiting groove, a mounting column, mounting threaded holes, a limiting slider, a fixing rod, a guide wheel, and a fixing bolt. The limiting groove is formed on the inner walls of both sides of the U-shaped fixing frame and on both sides of the mounting column. The limiting slider is slidably connected inside the limiting groove. Multiple sets of mounting threaded holes are evenly formed on the surfaces of the mounting column and the U-shaped fixing frame and communicate with the inside of the limiting groove. The fixing rod is fixedly installed between two sets of limiting sliders. The guide wheel is rotatably connected to the fixing rod. The fixing bolt cooperates with the mounting threaded holes to fix the limiting slider.
[0010] As a preferred embodiment, the plurality of mounting posts are spaced apart along the length of the base, and the number of guide wheels is the same as the number of pay-off reels.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] By setting up a wire feeding assembly and a tension adjustment assembly, the bracket and reinforcing ribs form a stable support structure, providing rigid fixation for the motor and shaft. Multiple quick-release wire feeding reels are connected to the shaft, allowing for quick replacement of copper stranded wire coils of different specifications. Operators can precisely adjust the position of the mounting column by moving the sliding limit slider within the limit groove. With the tightening action of the fixing bolts and mounting threaded holes, the position of the guide wheel can be flexibly adjusted, controlling the tension fluctuation of a single strand of copper stranded wire within a very small range. This effectively solves the entanglement problem caused by uneven tension in traditional devices and improves production efficiency.
[0013] By setting up a guide assembly, the U-shaped fixing frame and U-shaped mounting plate form a support structure. The number of multiple guide sleeves corresponds to the wire feeding reel, forming a parallel guide channel for multiple strands of copper wire. The inner wall of the guide sleeve is treated with a high-hardness wear-resistant coating to effectively reduce wire friction loss. Through precise aperture and axis positioning design, the movement trajectory of the copper wire is constrained, avoiding the conveying deviation problem caused by the lack of guidance in traditional devices. With the adjustment function of the tension adjustment assembly, this device can quickly respond to the production needs of copper wire of different specifications. By dynamically adjusting the wire feeding tension and guide path, stable wire feeding under multiple working conditions can be achieved, significantly improving product consistency and production adaptability efficiency.

[0020] 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.
[0021] Please see the appendix Figure 1 - Appendix Figure 3 and appendix Figure 5 A multi-strand copper wire production and feeding device includes a base 1, a feeding assembly 2, a tension adjusting assembly 3, and a guiding assembly 4. The feeding assembly 2 is used to place and feed out the copper stranded wire, the tension adjusting assembly 3 is used to adjust the tension of the copper stranded wire, and the guiding assembly 4 is used to guide the copper stranded wire. The feeding assembly 2 includes a bracket 201, a reinforcing rib 202, a motor 203, a rotating shaft 204, and a feeding reel 205. The bracket 201 is fixed to the rear end of the surface of the base 1, the reinforcing rib 202 is fixedly disposed between the bracket 201 and the base 1, and the motor 203 is mounted on the outer right side of the bracket 201. The bracket 201 and the reinforcing rib 202 are fixed by welding to form a stable triangular support structure, which enhances the overall rigidity, effectively disperses the vibration and torque generated by the motor 203 during operation, provides a high-precision rotation support environment for the rotating shaft 204, ensures that the feeding reel 205 rotates smoothly, and reduces the copper stranded wire feeding deviation caused by shaking.
[0022] The rotating shaft 204 is connected to the output shaft of the motor 203 and rotatably connected inside the bracket 201. Multiple sets of wire reels 205 are provided and sleeved on the rotating shaft 204. The multiple sets of wire reels 205 are detachably connected to the rotating shaft 204. The rotating shaft 204 is connected to the output shaft of the motor 203 by a key connection, which is in close cooperation with the output shaft of the motor 203 to efficiently transmit the power of the motor 203. At the same time, it is rotatably connected to the inside of the bracket 201 through bearings to ensure flexible rotation. The multiple sets of wire reels 205 are connected to the rotating shaft 204 by a quick-release flange structure, which facilitates quick replacement of copper stranded wires of different diameters and coil specifications, significantly improving the equipment changeover efficiency.
[0023] The tension adjustment assembly 3 includes a limiting slide groove 301, a mounting post 302, mounting threaded holes 303, a limiting slider 304, a fixing rod 305, a guide wheel 306, and a fixing bolt 307. The limiting slide groove 301 is formed on the inner walls of both sides of the U-shaped fixing frame 401 and on both sides of the mounting post 302. The limiting slider 304 is slidably connected to the inside of the limiting slide groove 301. Multiple sets of mounting threaded holes 303 are evenly formed on the surfaces of the mounting post 302 and the U-shaped fixing frame 401 and communicate with the inside of the limiting slide groove 301. The fixing rod 305 is fixedly installed between two sets of limiting sliders 304. The guide wheel 306 is rotatably connected to the fixing rod 305. The fixing bolt 307 is fixed. 7. The mounting threaded hole 303 is used to fix the limiting slider 304. Multiple mounting posts 302 are spaced apart along the length of the base 1, and the number of guide wheels 306 is the same as the number of pay-off reels 205. The limiting groove 301 and the limiting slider 304 form a linear guide pair. The dovetail groove structure design achieves precise positioning. The mounting posts 302 can slide freely along the limiting groove 301. The fixing bolt 307 passes through the mounting threaded hole 303 to fix the limiting slider 304 and firmly lock the mounting posts 302. This allows the operator to flexibly adjust the spatial position of the guide wheel 306 according to the tension requirements of the copper stranded wire, so as to achieve differentiated and precise control of the tension of multiple stranded copper wires.
[0024] Specifically, by setting up the wire feeding assembly 2 and the tension adjustment assembly 3, the bracket 201, with the reinforcing rib 202, provides a stable support for the motor 203 and the shaft 204, making the wire feeding reel 205 rotate more smoothly. Multiple sets of detachable wire feeding reels 205 can adapt to different specifications of copper stranded wire coils, reducing the time spent changing coils. The tension adjustment assembly 3, with the help of the limiting slide groove 301, the mounting column 302 and other structures, allows the operator to slide the limiting slider 304 and fix it with the fixing bolt 307 and the mounting threaded hole 303, flexibly adjust the position of the guide wheel 306, and accurately control the tension of each strand of copper stranded wire, avoiding tangling and knotting caused by uneven tension, ensuring production quality, improving production efficiency, and changing the shortcomings of traditional devices where tension is difficult to adjust.
[0025] Please see the appendix Figure 1 - Appendix Figure 4The guide assembly 4 includes a U-shaped fixing frame 401, a U-shaped mounting plate 402, and a guide sleeve 403. The U-shaped fixing frame 401 is fixed on the front surface of the base 1. The U-shaped mounting plate 402 is fixedly mounted on the U-shaped fixing frame 401. The guide sleeve 403 is set on the U-shaped mounting plate 402 and the copper stranded wire can pass through the guide sleeve 403. There are multiple sets of guide sleeves 403, which are the same number as the wire reel 205. The inner wall of the guide sleeve 403 is provided with a wear-resistant layer to reduce the wear between the copper stranded wire and the guide sleeve 403. The U-shaped fixing frame 401 is vertically fixed to the front surface of the base 1 by high-strength bolts, providing a stable mounting base for the U-shaped mounting plate 402. The U-shaped mounting plate 402 adopts a double-layer reinforcing rib design and is welded with the U-shaped fixing frame 401 to form a rigid whole, which together bears multiple sets of guide sleeves 403, ensuring a stable and reliable guiding process and preventing the copper stranded wire guiding accuracy from being affected by structural deformation.
[0026] Specifically, by setting up the guide component 4, the U-shaped fixing frame 401 and the U-shaped mounting plate 402 support multiple sets of guide sleeves 403, the number of which is the same as that of the wire feeding reel 205. The wear-resistant layer on the inner wall reduces the wear of copper wires. The guide sleeves 403 accurately constrain the direction of the copper stranded wires, solving the problem of copper wire deviation caused by the lack of guidance in traditional devices. Combined with the adjustability of the tension adjustment component 3, the device can flexibly control the wire feeding speed and tension according to the production needs of different specifications of copper stranded wires, adapting to various production scenarios, providing stable and accurate copper wire feeding for subsequent stranding processes, improving the quality of finished products and production adaptability. The multiple sets of guide sleeves 403 are the same in number and corresponding in position as the wire feeding reel 205, forming a parallel guide channel for multiple strands of copper wires. The inner wall is coated with a tungsten carbide wear-resistant coating, which effectively reduces the friction coefficient between the copper stranded wires and the guide sleeves 403, reducing the wear of the wire surface.
[0027] Working principle of this utility model: This utility model is a multi-strand copper wire production and feeding device. When the device is working, the motor 203 drives the rotating shaft 204 to rotate, which drives multiple feeding reels 205 mounted on it to feed out the copper stranded wire. The bracket 201 and the reinforcing rib 202 ensure the stable operation of the feeding assembly 2. The detachable feeding reel 205 facilitates quick replacement of copper stranded wire reels of different specifications. The fed copper stranded wire first passes through the tension adjustment assembly 3. The operator moves the sliding limit slider 304 within the limit groove 301 to adjust the position of the guide wheel 306 on the mounting column 302, and uses the fixing screw... The bolt 307 is fixed in place with the mounting threaded hole 303, precisely adjusting the tension of each copper strand to prevent tangling and knotting. Subsequently, the copper strand enters the guide assembly 4, and the U-shaped fixing bracket 401 and the U-shaped mounting plate 402 have the same number of guide sleeves 403 as the wire feeding reel 205. The wear-resistant inner wall layer reduces friction and precisely constrains the direction of the copper strand to prevent deviation. After being guided, the copper strand enters the subsequent process. Throughout the process, the device works together with each component to flexibly adjust the wire feeding speed and tension according to different production needs, providing a reliable guarantee for the stable production of copper strand and the subsequent stranding process. At this point, the entire process is completed.
