Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire feeding machines, and in particular to a double-headed shafted power wire feeding machine. Background Technology
[0002] The wire unwinding machine, a key piece of equipment in the metal wire processing process, primarily functions to release the metal wire from the unwinding reel and, after a series of adjustments and guidance, precisely feed it into the stranding machine for subsequent stranding operations. Wire unwinding machines play a vital role in various fields such as wire and cable manufacturing and metal wire braiding; their performance stability and accuracy directly affect the quality and efficiency of subsequent processing.
[0003] A wire feeding machine typically includes core components such as an unwinding shaft, adjusting rollers, and guide rollers. The unwinding shaft holds the unwinding reel. After the metal wire is released from the unwinding reel, it passes sequentially through the adjusting rollers and guide rollers for guidance and adjustment, ensuring the wire's position and tension during transport. These components usually function through mechanical structures or motor drives, providing fundamental assurance for the wire feeding operation.
[0004] Existing wire feeding machines have the following drawbacks: 1. Most existing feeding machines can only feed single metal wires, which is insufficient for large-scale production environments, resulting in low efficiency and failing to meet the demands of fast and efficient wire feeding operations. 2. The matching between wire feeding speed and wire feeding speed has always been a technical challenge in the wire feeding machine field. Because the wire feeding speed constantly changes during the wire feeding process, existing feeding machines often cannot achieve precise matching with the wire feeding speed. This can easily lead to the metal wire becoming loose or too tight during transport, thus affecting the quality and efficiency of the wire feeding. Utility Model Content
[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides a dual-head shafted power wire feeding machine, which can effectively solve the technical problems of low working efficiency and the inability to automatically adjust the wire feeding speed.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] A dual-head shafted power wire feeding machine includes a machine body with a wire feeding assembly. The wire feeding assembly includes an unwinding shaft, an adjusting roller, and a guide roller. The unwinding shaft carries the unwinding reel. The unwinding shaft, adjusting roller, and guide roller are parallel to each other. During operation, the metal wire on the unwinding reel passes sequentially through the adjusting roller and guide roller to the stranding machine. The adjusting roller keeps the metal wire taut, and the guide roller guides the position of the metal wire during transport. One end of the unwinding shaft is rotatably connected to the machine body. The machine body houses a drive motor and a processor. The drive motor rotates the unwinding shaft. The wire feeding assembly is configured with… There are two sets of wire feeding assemblies, which are respectively located on both sides of the machine body. The wire feeding assembly also includes a tensioning frame and a tensioning cylinder. The tensioning frame is connected to the machine body via a rotating shaft and can rotate relative to the machine body around the rotating shaft. One end of the tensioning frame is rotatably mounted on the adjusting roller. The two ends of the tensioning cylinder are rotatably connected to the machine body and the tensioning frame, respectively. The tensioning cylinder is used to push the tensioning frame to move the adjusting roller away from the unwinding shaft. A turntable coaxial with the rotating shaft is mounted on the tensioning frame. An angle sensor for detecting the rotation angle of the turntable is mounted on the machine body. The angle sensor and the drive motor are both connected to the processor.
[0008] Furthermore, the tensioning frame is provided with two coaxial positioning holes. The turntable is aligned with the positioning hole at one end near the machine body. The rotating shaft passes through the turntable and the two positioning holes in sequence. With the rotating shaft as a reference, the two ends of the tensioning frame are the adjustment end and the limiting end, respectively. The adjustment roller is rotatably set at the adjustment end.
[0009] Furthermore, a limiting plate is provided on the body, the limiting plate is arranged around the axis of the rotating shaft, and the limiting end of the tensioning frame can contact the surface of the limiting plate, thereby limiting the maximum swing angle of the tensioning frame.
[0010] Furthermore, an elastic buffer block is provided at the end of the limiting plate near the tensioning frame.
[0011] Furthermore, the surface of the machine body is provided with a limit switch, and the drive motor is connected in series with the limit switch. When the limit switch is open, the drive motor is de-energized. The side wall of the tensioning frame is provided with a trigger, which can be disconnected by the limit switch.
[0012] Furthermore, the guide roller is provided with several evenly distributed guide ring grooves, and each metal wire passes through several guide ring grooves during operation.
[0013] Furthermore, the output shaft and unwinding shaft of the drive motor are equipped with transmission wheels, and the two transmission wheels are connected by a belt.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By setting up two sets of wire feeding components, located on both sides of the machine body, multiple metal wires can be fed simultaneously, improving work efficiency. Especially in production environments requiring the stranding of a large number of metal wires, this significantly shortens operation time and reduces production costs. Furthermore, the ability to process multiple metal wires in parallel enhances the overall coordination of the production line, making the entire production process smoother.
[0016] 2. The drive motor and tensioning frame are linked. The drive motor not only drives the unwinding shaft to rotate and feed the wire, but also actively adjusts its speed under the control of the processor. This ensures that the wire feeding speed matches the stranding speed, effectively preventing problems such as loose or overly tight metal wire caused by speed mismatch. When the stranding speed slows down or speeds up, the tensioning cylinder will promptly push or pull the tensioning frame to swing, moving the adjusting roller away from or closer to the unwinding shaft, thus maintaining the tautness of the metal wire. The swing of the tensioning frame drives the turntable to rotate. The angle sensor can accurately detect changes in the turntable's angle and send the data to the processor in real time. Based on the received angle data, the processor quickly adjusts the speed of the drive motor to ensure continuous and stable wire feeding, improving the stability and reliability of the production line.

Detailed Implementation
[0022] 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.
[0023] The following is combined with Figures 1-4A detailed description of the dual-head shafted power wire feeding machine of this utility model is provided below:
[0024] The dual-head shafted power wire feeding machine of this embodiment includes a body 1, on which a wire feeding assembly is provided. The wire feeding assembly includes an unwinding shaft 2, an adjusting roller 3, and a guide roller 4. The unwinding shaft 2 is used to hang the unwinding reel. The unwinding shaft 2, the adjusting roller 3, and the guide roller 4 are parallel to each other. During operation, the copper wire on the unwinding reel passes through the adjusting roller 3 and the guide roller 4 in sequence to be guided to the stranding machine. The adjusting roller 3 is used to keep the copper wire taut. The guide roller 4 is used to guide the position of the copper wire during feeding. The guide roller 4 is provided with several evenly distributed guide ring grooves. During operation, each copper wire passes through several guide ring grooves, which provides more stable and precise guidance for the feeding of the copper wire. With evenly distributed wire grooves, each copper wire receives independent support and guidance, effectively preventing crossover and tangling. One end of the unwinding shaft 2 is rotatably connected to the machine body 1. The machine body 1 contains two drive motors 5 and a processor. The two drive motors 5 respectively drive the two unwinding shafts 2 to rotate. Transmission wheels 6 are installed on the output shafts of the drive motors 5 and the unwinding shafts 2, and the two transmission wheels 6 are connected by a belt 7. Two sets of wire-feeding assemblies are provided, located on opposite sides of the machine body 1. Both sets of wire-feeding assemblies can operate independently. The component also includes a tensioning frame 8 and a tensioning cylinder 9. The tensioning frame 8 is connected to the machine body 1 via a rotating shaft 10. The tensioning frame 8 can rotate relative to the machine body 1 with the rotating shaft 10 as the axis. One end of the tensioning frame 8 is rotatably provided on the adjusting roller 3. The two ends of the tensioning cylinder 9 are rotatably connected to the machine body 1 and the tensioning frame 8, respectively. The tensioning cylinder 9 is used to push the tensioning frame 8 to move the adjusting roller 3 away from the unwinding shaft 2. A turntable 11 coaxial with the rotating shaft 10 is provided on the tensioning frame 8. An angle sensor 12 is provided on the machine body 1 to detect the rotation angle of the turntable 11. The angle sensor 12 and the drive motor 5 are both connected to the processor.
[0025] By setting up two sets of wire feeding components, located on both sides of the machine body 1, the machine can feed multiple copper wires simultaneously, improving work efficiency. This is especially beneficial in production environments requiring the stranding of large quantities of copper wire, significantly shortening operation time and reducing production costs. Furthermore, the ability to process multiple copper wires in parallel enhances the overall coordination of the production line, making the entire production process smoother.
[0026] The drive motor 5 is linked with the tensioning frame 8. The drive motor 5 not only drives the unwinding shaft 2 to rotate and feed the wire, but also actively adjusts its speed under the control of the processor. This ensures the matching of the wire feeding speed and the stranding speed, effectively preventing problems such as loose or overly tight copper wire caused by speed mismatch. When the stranding speed slows down or speeds up, the tensioning cylinder 9 promptly pushes or pulls the tensioning frame 8 to swing, causing the adjusting roller 3 to move away from or closer to the unwinding shaft 2, thus maintaining the tautness of the copper wire. The swinging of the tensioning frame 8 drives the turntable 11 to rotate. The angle sensor 12 accurately detects the angle change of the turntable 11 and sends the data to the processor in real time. Based on the received angle data, the processor quickly adjusts the speed of the drive motor 5 to ensure continuous and stable copper wire feeding, improving the stability and reliability of the production line.
[0027] The tensioning frame 8 is provided with two coaxial positioning holes. The turntable 11 is aligned with the positioning hole near the end of the machine body 1. The rotating shaft 10 passes through the turntable 11 and the two positioning holes in sequence. With the rotating shaft 10 as the reference, the two ends of the tensioning frame 8 are the adjustment end and the limiting end, respectively. The adjusting roller 3 is rotatably set at the adjustment end. Through the cooperation of the two coaxial positioning holes and the rotating shaft 10, a stable connection between the turntable 11 and the tensioning frame 8 is ensured, effectively preventing axial shaking during the swing of the turntable 11, making the swing of the turntable 11 more stable, enhancing the stability of the copper wire during the wire feeding process, and thus further ensuring the quality of copper wire delivery. The machine body 1 is provided with a limiting plate 13, which is set around the axis of the rotating shaft 10. The limiting end of the tensioning frame 8 can contact the surface of the limiting plate 13, thereby limiting the maximum swing angle of the tensioning frame 8, effectively avoiding equipment damage or metal wire slack caused by excessive swing angle. An elastic buffer block is provided at one end of the limiting plate 13 near the tensioning frame 8. The addition of the elastic buffer block provides a buffering effect for the contact between the tensioning frame 8 and the limiting plate 13, effectively reducing the impact and noise caused by direct contact.
[0028] A limit switch 14 is provided on the surface of the body 1. The limit switch 14 is located close to the drive motor 5 connected in series with the limit switch 14. When the limit switch 14 is open, the drive motor 5 is de-energized. A trigger 15 is provided on the side wall of the tensioning frame 8. The trigger 15 can open the limit switch 14. During the wire feeding process, when the copper wire breaks due to excessive tension, the tensioning frame 8 will swing rapidly to the limit position under the action of the tensioning cylinder 9. At this time, the trigger 15 will touch the limit switch 14, causing the limit switch 14 to open and thus stopping the drive motor 5. The machine will automatically stop working after the wire breaks.
[0029] Working process: The unwinding reel is installed on the unwinding shaft 2. The copper wire on the unwinding reel is placed on the guide roller 4 after passing over the adjusting roller 3 and led into the stranding machine. The tensioning cylinder 9 pushes the tensioning frame 8 to swing away from the stranding machine, thus tauting the copper wire. The stranding machine and drive motor 5 are turned on, and the unwinding shaft 2 rotates, feeding the copper wire into the stranding machine. When the stranding speed slows down, the tensioning cylinder 9 pushes the tensioning frame 8 to swing, moving the adjusting roller 3 away from the unwinding shaft 2, thereby maintaining the tautness of the copper wire. The swing of the tensioning frame 8 drives the turntable 11 to rotate. The angle sensor 12 can accurately detect the angle change of the turntable 11 and send the data to the processor in real time. Based on the received angle data, the processor quickly adjusts and reduces the speed of the drive motor 5 to match the wire feeding speed with the stranding speed. When the stranding speed speeds up, the tensioning cylinder 9 pulls the tensioning frame 8, bringing the adjusting roller 3 closer to the unwinding shaft 2, thereby maintaining the tautness of the copper wire while reducing the tension of the copper wire, preventing the copper wire from breaking due to excessive tension. The oscillation of the tensioning frame 8 causes the turntable 11 to rotate. The angle sensor 12 can accurately detect the angle change of the turntable 11 and send the data to the processor in real time. Based on the received angle data, the processor quickly adjusts and increases the speed of the drive motor 5 to match the wire feeding speed with the stranding speed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
