Description
Technical Field
[0001] This utility model relates to the technical field of aluminum wire production equipment, and in particular to an aluminum wire feeding device. Background Technology
[0002] In the aluminum wire production industry, the pay-off frame is a crucial feeding device in the early stages of aluminum wire processing. Its function is to release the coiled aluminum wire in an orderly manner, providing continuous and stable raw material transport for subsequent processing steps such as rolling and drawing. With the expansion of aluminum wire production scale and the improvement of automation, the requirements for the stability and reliability of the pay-off frame are becoming increasingly stringent.
[0003] Existing wire feeding frames have a relatively simple structural design, mainly relying on components such as motors and rollers to achieve the basic function of feeding aluminum wire. However, in actual production, due to factors such as unstable aluminum wire winding and equipment vibration, multiple aluminum wires can easily enter the die opening simultaneously. Once this happens, the tension of the aluminum wire at the die opening changes drastically, which can not only directly break the aluminum wire, causing a large waste of raw materials, but also damage the die due to "running empty" (continuous operation without aluminum wire passing through), increasing equipment maintenance costs and downtime.
[0004] Meanwhile, traditional wire feeding racks lack effective detection and intervention mechanisms for multiple wires passing through, relying entirely on manual inspections to detect anomalies. However, manual inspections suffer from problems such as delayed response and missed detections, making it difficult to handle situations promptly when multiple wires pass through, further exacerbating the impact of production failures.

[0030] The following is in conjunction with the appendix Figure 1-5 The present invention will provide a more detailed description of an embodiment of an aluminum wire unwinding device.
[0031] An aluminum wire unwinding device, such as Figure 1 , 2 As shown, it includes a wire feeding frame 1 and a wire feeding reel assembly 2.
[0032] The wire feeding frame 1 includes a base 11 and a column 12. The base 11 has a conical structure and is fixed to the ground with screws. The column 12 is vertically fixed to the center of the upper surface of the base 11, and a cantilever 13 is vertically installed on the top of the column 12. One end of the cantilever 13 is hinged to the top of the column 12, and the other end is suspended downward to install a wire cutting roller group 4. An electromagnetic sensing coil 5 is connected to the bottom of the wire cutting roller group 4.
[0033] The wire feeding reel group 2 includes a traction wheel 21, a lifting wheel 22, an active guide wheel 23, and a driven guide wheel 24. The traction wheel 21 and the lifting wheel 22 are respectively installed at the upper and lower ends of the column 12, and the traction wheel 21 and the lifting wheel 22 are distributed vertically. The active guide wheel 23 is installed on the side wall of the column 12 through a bracket, and a drive mechanism 6 is connected to one side of the active guide wheel 23. The driven guide wheel 24 is installed at both ends of the cantilever 13 through a rotating shaft. The aluminum wire passes through the traction wheel 21, the lifting wheel 22, the active guide wheel 23, and the driven guide wheel 24 in sequence, and then passes through the wire shearing roller group 4 and the electromagnetic sensing coil 5.
[0034] Specifically, the base 11 utilizes its large conical contact area to enhance the overall anti-overturning capability of the equipment, providing a stable support foundation for the column 12 and the upper structure. The column 12 is vertically welded or connected to the center of the upper surface of the base 11 by high-strength bolts, and is made of high-strength metal to ensure rigidity and stability under vertical load. The top of the column 12 is connected to one end of the cantilever 13 via a hinge, such as a pin with a wear-resistant bushing, allowing the cantilever 13 to rotate within a certain angle range around the hinge point, adapting to the needs of aluminum wire conveying at different heights and along different paths. The cantilever 13 is a horizontally extending rod-like structure, made of lightweight, high-strength alloy material, which reduces its own weight while ensuring rigidity, thus reducing the load on the column 12.
[0035] The traction wheel 21 and the lifting wheel 22 are respectively mounted on the upper and lower ends of the column 12 via bearing seats 42. The traction wheel 21 is close to the base 11 and is used to receive the starting end of the aluminum wire coil on the ground. The lifting wheel 22 is located on the upper part of the column 12, distributed vertically with the traction wheel 21 to form the initial lifting and guiding path for the aluminum wire. The two are rotatably connected by the bearing seats 42 to ensure smooth and low-friction when the aluminum wire passes around. The active guide wheel 23 is fixed to the side wall of the column 12 by a bracket. The bracket is a metal bracket made of angle iron welded or bolted, and the position of the bracket is precisely adjusted according to the overall layout and the aluminum wire conveying path. The driven guide wheel 24 is mounted on both ends of the cantilever 13 via a rotating shaft. The rotating shaft and the cantilever 13 are connected by bearings to ensure rotational flexibility. The aluminum wire passes around the traction wheel 21, the lifting wheel 22, the active guide wheel 23 and the driven guide wheel 24 in sequence, and finally passes through the wire shearing roller group 4 and the electromagnetic sensing coil 5, and falls naturally under its own gravity to facilitate the subsequent wire drawing and winding processes.
[0036] In this embodiment, as Figure 2 As shown, the electromagnetic sensing coil 5 is connected to the bottom of the wire shearing roller group 4 via an elastic connector 7. One end of the elastic connector 7 is fixed to the metal frame of the wire shearing roller group 4, and the other end is connected to the mounting base of the electromagnetic sensing coil 5, allowing the electromagnetic sensing coil 5 to elastically displace in the vertical or small horizontal direction. The electromagnetic sensing coil 5 adopts a nested large and small ring structure, coaxially arranged, with a large coil nested within a small coil. It utilizes the principle of electromagnetic induction to detect the quantity and state of aluminum wire passing through.
[0037] Specifically, the electromagnetic sensing coil 5 consists of two nested ring structures of different sizes, with the inner diameter of the larger ring structure slightly larger than the outer diameter of the smaller ring structure. Both rings utilize metal coils with electromagnetic induction capabilities or ring components integrating electromagnetic induction modules, and are connected to the bottom of the wire shearing roller group 4 via an elastic connector 7. The elastic connector 7 possesses a certain degree of elastic deformation and reset function, such as using a spring, elastic rubber, or an elastic pull rope. The elastic coefficient of the elastic connector 7 has been tested and adapted to ensure that when a single aluminum wire passes through the smaller ring structure, the smaller coil is slightly compressed by the aluminum wire but does not experience significant displacement. When multiple aluminum wires pass through, the compressive force on the smaller coil exceeds the initial tension of the elastic connector 7, causing the smaller coil to displace relative to the larger coil.
[0038] During normal production, a single aluminum wire passes through the small ring structure, and the small coil maintains a stable electromagnetic induction signal due to the presence of the aluminum wire. When multiple aluminum wires pass through simultaneously, the multi-wire compression causes the small coil to compress the elastic connector 7 and displace, resulting in a change in the electromagnetic induction coupling state between the large and small coils. The electromagnetic sensing coil 5 is equipped with a signal processing module, which is integrated into the control box of the column 12 or cantilever 13 to detect signal anomalies. This allows for accurate identification of single and multi-wire passage states, providing a reliable signal source for subsequent shutdown protection. The elastic connector 7 enables the electromagnetic sensing coil 5 to have adaptive adjustment capabilities, preventing false triggering of detection due to slight vibration of a single aluminum wire, thus improving detection accuracy and equipment anti-interference capabilities. The nested structure simplifies the detection logic, utilizing the inherent characteristics of electromagnetic induction without the need for complex mechanical triggering structures, reducing the probability of failure and maintenance costs.
[0039] In this embodiment, as Figure 4 , 5 As shown, the cantilever 13 is a horizontal rod and is hinged to the top of the column 12. The hinge point uses a joint bearing with locking bolts, which can be manually or electrically adjusted and locked. The inclined support arm 3 is an inclined rod, with one end connected to the middle of the cantilever 13 through a hinge with a bearing, and the other end connected to the side wall of the column 12 through a hinge as well. The three form a stable triangular structure.
[0040] Specifically, the length of the inclined support arm 3 is adapted to the rotation range of the cantilever 13, ensuring effective triangular support at different angles of the cantilever 13. When the angle of the cantilever 13 needs to be adjusted to adapt to the aluminum wire conveying path, the inclined support arm 3 rotates with the cantilever 13, and the bearing of the hinge ensures flexible and adaptive adjustment, always maintaining the supporting force on the cantilever 13. Utilizing the principle of triangular stability, the horizontal load of the cantilever 13, such as aluminum wire tension and the self-weight of the cantilever 13, is converted into the axial force of the inclined support arm 3 and the supporting force of the column 12, and the stress is dispersed, preventing the cantilever 13 from deforming or breaking due to excessive stress at a single point.
[0041] In this embodiment, as Figure 2 As shown, the wire shearing roller assembly 4 includes at least two parallel shearing rollers 41. The shearing rollers 41 are mounted on the suspension frame 131 at the end of the cantilever 13 via high-precision bearing seats 42. The bearing seats 42 have good coaxiality and perpendicularity, ensuring the parallelism of the shearing rollers 41. The surface of the shearing rollers 41 can be treated with chrome plating or sprayed with a wear-resistant coating to improve wear resistance and the surface protection of the aluminum wire. The wire shearing roller assembly 4 is mounted below the end of the cantilever 13 via the suspension frame 131. The suspension frame 131 is a metal frame welded or bolted to the end of the cantilever 13 to ensure that the wire shearing roller assembly 4 is vertically suspended and precisely aligned with the aluminum wire conveying path. The shearing rollers 41 within the wire shearing roller assembly 4 are mounted parallel to each other via the bearing seats 42. The bearing seats 42 are of high precision and low friction type, ensuring smooth rotation of the shearing rollers 41. When the aluminum wire passes through the gap between the two shearing rollers 41, horizontal limiting and guidance are achieved, preventing the aluminum wire from deviating during conveying.
[0042] Specifically, when the aluminum wire passes through the gap between the two shearing rollers 41, the shearing rollers 41 limit the aluminum wire on both sides. Utilizing the rotational characteristics of the rollers, they rotate synchronously with the aluminum wire conveying, converting sliding friction into rolling friction, reducing the aluminum wire conveying resistance and surface wear. When multiple rollers are used, the horizontal freedom of the aluminum wire is further constrained, ensuring that the aluminum wire passes through the shearing roller group 4 in a straight line and accurately enters the detection area and processing steps of the subsequent electromagnetic sensing coil 5. By setting the shearing roller group 4 to effectively limit the aluminum wire conveying path, misjudgment of multiple wires due to aluminum wire deviation is avoided, thereby improving the accuracy of multi-wire detection. Furthermore, using rolling friction instead of sliding friction can reduce scratches and wear on the aluminum wire surface, ensuring the quality of aluminum wire products, especially suitable for high-precision aluminum wire production. In addition, the multi-roller structure can adjust the spacing and number according to production needs, adapting to the production of aluminum wires with different diameters and tensions, enhancing the production compatibility of the equipment.
[0043] In this embodiment, as Figure 4 , 5 As shown, the drive mechanism 6 consists of a motor mounting bracket 61, a drive motor 62, and a reducer 63. The motor mounting bracket 61 adopts a steel plate welding or bolt splicing structure and is rigidly connected to the side wall of the column 12 by bolts to ensure that the drive motor 62 is installed stably. The drive motor 62 is a speed-regulating motor with an appropriate power, and its speed can be adjusted according to the production rhythm. Its output end is connected to the input shaft of the reducer 63 through a coupling (such as a flexible coupling with buffering and vibration reduction functions). The reducer 63 adopts a gear reduction or worm gear reduction structure, and its output end is coaxially connected to the drive guide wheel 23.
[0044] Specifically, when the drive motor 62 is energized, the power is transmitted to the reducer 63 via the coupling. The reducer 63 reduces speed and increases torque through gear or worm gear meshing, outputting power to the drive guide wheel 23, which then rotates. As the drive guide wheel 23 rotates, it utilizes the friction between the grooves on the wheel surface and the aluminum wire to guide the aluminum wire along the path of the wire feeding wheel assembly 2. By adjusting the speed of the drive motor 62, a stable and adjustable power output is provided, precisely controlling the aluminum wire feeding speed to adapt to the aluminum wire feeding speed requirements of different production processes, ensuring production continuity and product quality consistency. The torque-increasing effect of the reducer 63 allows the drive guide wheel 23 to effectively overcome aluminum wire tension and multi-wheel rotation friction resistance, ensuring stable feeding even in long-distance, multi-wheel guiding scenarios. The rigid connection of the motor mounting bracket 61 and the buffering and vibration reduction of the coupling reduce the impact of motor vibration on the stability of aluminum wire feeding, while protecting the transmission components of the motor and reducer 63, extending the service life of the equipment.
[0045] In this embodiment, both the active guide wheel 23 and the driven guide wheel 24 have semi-circular grooves on their surfaces. The radius of the grooves is slightly larger than that of commonly used aluminum wires. By replacing the guide wheels with different groove sizes, various diameters of aluminum wires can be adapted. A flexible protective layer, such as rubber, polyurethane, or other elastic and wear-resistant materials, is pasted on the inner wall of the grooves.
[0046] Specifically, the semi-circular groove forms a wrapping and limiting effect on the aluminum wire. Combined with the flexible protective layer, it not only restricts the radial runout of the aluminum wire during the conveying process, but also buffers the contact stress between the aluminum wire and the wheel surface through the flexible material, avoiding surface damage to the aluminum wire caused by hard contact.
[0047] In this embodiment, the line connecting the centers of the active guide wheel 23 and the driven guide wheel 24 forms an angle of 15-30° with the vertical direction.
[0048] Specifically, the 15-30° angle design allows the aluminum wire to form a specific tension angle between the two wheels. By utilizing the synergistic effect of gravity and tension, it reduces the risk of aluminum wire accumulation and tangling, and lowers the probability of multi-wire or broken wire failures caused by poor conveying. It can be adapted to the production of aluminum wires of various diameters. By changing the guide wheels, the applicability of the equipment can be expanded, improving the cost-effectiveness and production flexibility of the equipment.
[0049] The working principle of this utility model:
[0050] During normal production, a single aluminum wire is laid out at a set speed and tension, smoothly passing through the small induction coil. The electromagnetic induction sensor detects in real time that the small induction coil is in a normal position and continuously sends a normal signal to the controller, ensuring stable equipment operation. However, when two or more aluminum wires pass through simultaneously due to abnormal wire winding or equipment vibration, the multiple wires compress and pull the small induction coil, causing it to deviate from its initial position. The electromagnetic induction sensor then fails to detect the normal state of the small induction coil and immediately transmits an abnormal signal to the controller. Upon receiving the abnormal signal, the controller quickly cuts off the power supply circuit to the drive motor 62 according to a preset program, stopping the machine. When staff receive the equipment shutdown alarm, they go to the site to investigate, clear the multiple wires, and restore the wire laying status. After confirming that the fault has been resolved, they send a reset signal to the controller via the reset button on the control panel. The controller then restarts the equipment, the drive motor 62 resumes laying, and the production process continues.
[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
