Description
Technical Field
[0001] This utility model relates to an unwinding device, and more particularly to an unwinding device for drawing copper rod wire. Background Technology
[0002] During the copper rod drawing process, the unwinding equipment is used to smoothly unfold the coiled copper rod and feed it into subsequent processing steps. To ensure the continuity and stability of the copper rod during the drawing process, the unwinding equipment needs to have precise tension control, stable unwinding speed, and good guiding function. Existing unwinding equipment typically uses a combination of mechanical transmission and electronic control systems to meet the processing requirements of copper rods of different specifications.
[0003] When using existing copper rod unwinding equipment, operators install the copper rod coil onto the unwinding machine's bracket and guide one end of the copper rod into the drawing equipment. Next, they start the unwinding machine's motor and adjust the unwinding speed via a frequency converter to ensure it matches the speed of subsequent drawing processes. Then, they adjust the tension during the unwinding process using a tension controller to prevent the copper rod from becoming loose or too tight. Finally, throughout the entire unwinding process, operators must closely monitor the equipment's operating status and promptly handle any abnormalities to ensure continuous production. Although existing copper rod unwinding equipment meets production needs to a certain extent, it still has some shortcomings. Its traditional mechanical transmission unwinding accuracy is not high. As the diameter of the copper rod coil gradually decreases, it is difficult to maintain consistent unwinding speed and tension. When connecting to subsequent equipment, tension control relies on manual adjustment. Improper tension control can easily cause problems such as copper rod breakage or deformation, affecting the quality and production efficiency of subsequent processed products. Utility Model Content

A motor is mounted below the unwinding turntable, driving it to rotate on the support seat. A telescopic component is concentrically and vertically mounted on the unwinding turntable, consisting of a lifting rod and several circumferentially arranged tension plates. The tension plates are slidably connected to the unwinding turntable. The lifting rod is connected to the tension plates via a connecting rod. One end of the lifting rod of the telescopic component is connected to... There is a power component that drives the lifting rod to rise and fall, thereby enabling the telescopic component to expand and contract on the unwinding turntable. An arc-shaped wire guide frame is provided on the front left side of the support base. Several wire guide rollers are arranged along the arc inside the arc-shaped wire guide frame. A worktable is provided on the right side of the base plate. Two mounting seats are installed at intervals on the top of the worktable.

Multiple rollers are arranged at intervals in the lower part of the fixed base. Multiple sliding seats are slidably provided in the upper part of the fixed base. Straightening wheels are rotatably provided in each sliding seat. Multiple hydraulic cylinders are vertically installed on the top of the fixed base. The hydraulic rods of the hydraulic cylinders are connected to the top of a sliding seat of the same fixed base. The hydraulic cylinders drive the sliding seats to move up and down in the fixed base, thereby driving the straightening wheels to move up and down.
[0007] Optionally, it also includes a limiting roller, with at least one limiting roller rotatably provided on the front side of the arc-shaped lead frame, and the limiting roller is arranged in the same direction as the lead roller.
[0008] Optionally, it also includes a guide seat, a cylinder, a connecting frame, and a pressing rod.

[0009] Optionally, it also includes auxiliary rollers, with auxiliary rollers installed on the left and right sides and the left side of the rear part of the support.
[0010] The present invention has the following advantages: 1. The present invention divides the unwinding device into two independent areas, namely the copper rod unwinding area and the transfer area, and sets an interval area between the two as a buffer zone.

Detailed Implementation
[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] Example 1
[0021] An unwinding device for drawing copper rods, such as Figure 1-5As shown, the assembly includes a base plate 1, a support base 2, an unwinding turntable 3, a telescopic component 4, an arc-shaped lead frame 5, a lead roller 51, a worktable 6, a mounting base 7, a pressure roller 71, and a wire conveying roller 72. The support base 2 is fixedly mounted on the upper left side of the base plate 1. The unwinding turntable 3 is rotatably mounted on the upper part of the support base 2. A motor is mounted on the lower part of the unwinding turntable 3, driving the unwinding turntable 3 to rotate on the support base 2. This motor can precisely control the rotation speed and direction of the unwinding turntable 3, ensuring that the copper rod 200 maintains a uniform speed during unwinding, avoiding tension changes or breakage due to uneven speed. A telescopic component 4 is concentrically and vertically mounted on the unwinding turntable 3. It consists of a lifting rod and several circumferentially arranged tension plates. The tension plates are slidably connected to the unwinding turntable 3. The lifting rod and tension plates are connected by a connecting rod. One end of the lifting rod of the telescopic component 4 is connected to a power component, which drives the lifting rod to rise and fall, thereby allowing… The telescopic component 4 expands and contracts on the unwinding turntable 3. When the mother roll 100 is placed on the unwinding turntable 3, the telescopic component 4 expands and tightens the inner side of the mother roll 100, fixing the mother roll 100 to the telescopic component 4. This ensures that the mother roll 100 will not loosen or shift during unwinding, thereby improving the stability and reliability of unwinding. An arc-shaped guide frame 5 is provided on the front left side of the support base 2. Several guide rollers 51 are arranged along the arc inside the arc-shaped guide frame 5. These guide rollers 51 can guide the copper rod 200 from... The unwinding turntable 3 extends from the right rear side, then passes to the left around the outside of the arc-shaped lead frame 5, and then to the right between the pressure roller 71 and the wire conveying roller 72 inside the left mounting seat 7. The design of the arc-shaped lead frame 5 and the wire conveying roller 51 not only reduces the friction of the copper rod 200 during transmission, but also ensures the smoothness of the copper rod 200's path, avoiding jamming or damage caused by complex paths. A worktable 6 is provided on the right side of the base plate 1, and two mounting seats 7 are spaced apart on the top of the worktable 6. The upper part of each mounting seat 7 is connected by a... A pressure roller 71 is connected to an elastic element and slidably connected to a mounting base 7. A wire-transfer roller 72 is rotatably mounted in the lower part of the mounting base 7, with one end of each roller connected to a drive motor. The wire-transfer roller 72 and the pressure roller 71 within the same mounting base 7 are spaced apart, and both contain tension sensors. The cooperative design of the pressure roller 71 and the wire-transfer roller 72 effectively clamps and transmits the copper rod 200, ensuring that the copper rod 200 maintains appropriate tension during transmission and avoiding overstretching or slack. Furthermore, the design of the elastic element and the slidable connection allows the pressure roller 71 to automatically adjust the pressure according to the actual condition of the copper rod 200, further enhancing the system's adaptability and flexibility.
[0022] During unwinding, the mother roll 100 is placed on the unwinding turntable 3, ensuring that the mother roll 100 is located around the telescopic component 4. The telescopic component 4 consists of a lifting rod and several tension plates arranged in a circle. The lifting rod is raised and lowered by a power component, causing the tension plates to open and tighten the inner side of the mother roll 100; see reference. Figure 5The copper rod 200 is led out from the right rear side of the unwinding turntable 3 and passes to the left around the outside of the arc-shaped lead frame 5. Multiple guide rollers 51 are arranged along the arc inside the arc-shaped lead frame 5. These guide rollers 51 effectively guide the path of the copper rod 200, reduce friction, and ensure smooth transmission of the copper rod 200. Subsequently, the copper rod 200 is introduced between the pressure roller 71 and the wire-transfer roller 72 in the left mounting seat 7, and then further introduced between the pressure roller 71 and the wire-transfer roller 72 in the right mounting seat 7, finally being introduced to the right into the wire drawing machine. The entire path design is reasonable, avoiding complex bends and jams. This design improves work efficiency. Within each mounting base 7, the pressure roller 71 is slidably connected to the mounting base 7 via an elastic element, while the wire conveying roller 72 is driven to rotate by a drive motor. The gap between the pressure roller 71 and the wire conveying roller 72, along with the built-in tension sensor, allows for real-time monitoring and adjustment of the tension of the copper rod 200. When the copper rod 200 is subjected to excessive tension, the pressure roller 71 automatically adjusts the pressure to maintain appropriate tension, preventing the copper rod from breaking or deforming. Furthermore, the design of the elastic element allows the pressure roller 71 to be flexibly adjusted according to the actual condition of the copper rod 200, further enhancing the stability and reliability of the system.
[0023] By dividing the unwinding equipment into two independent areas—the copper rod 200 unwinding area and the transfer area—and setting a buffer zone between them, the existence of the buffer zone can effectively prevent the copper rod 200 from breaking or deforming due to sudden changes in tension or strain. The intelligent control system automatically adjusts the rotation speed of the unwinding turntable 3 and the transfer roller 72 based on the data fed back by the tension sensor, ensuring the coordination and consistency of the unwinding and transfer speeds, thereby achieving the smoothness and efficiency of the entire process.
[0024] Example 2
[0025] Based on Example 1, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it also includes a fixed seat 8, a protective cover 61, a roller 81, a hydraulic cylinder 82, a sliding seat 83 and a straightening wheel 831. The top of the workbench 6 is provided with two mounting seats 7. The two mounting seats 7 and the two fixed seats 8 are arranged in an alternating manner on the same horizontal line. This alternating arrangement design ensures that the copper rod 200 has a smoother path during transmission, reduces bending and friction, and improves transmission efficiency.
[0026] Protective covers 61 are provided between the front and rear sides of the fixed base 8. The protective covers 61 not only protect the internal components, but also effectively prevent external impurities from entering, ensuring the cleanliness and safe operation of the equipment. The fixed base 8 has a cable tray for guiding the copper rod 200 through. Multiple rollers 81 are arranged at intervals in the lower part of the fixed base 8. These rollers 81 can reduce the friction of the copper rod 200 during transmission, allowing it to pass through the fixed base 8 more smoothly. The surface of the rollers 81 is specially treated, with good wear resistance and low coefficient of friction, further extending the service life and reducing maintenance costs.
[0027] Multiple sliding seats 83 are slidably arranged in the upper part of the fixed base 8, and each sliding seat 83 is rotatably equipped with a straightening wheel 831. The straightening wheel 831 can be flexibly adjusted in position by the up and down movement of the sliding seat 83 within the fixed base 8, thereby performing precise straightening of the copper rod 200. Multiple hydraulic cylinders 82 are vertically mounted on the top of each fixed base 8, and the hydraulic rods of each hydraulic cylinder 82 are connected to the top of one of the sliding seats 83 within the same fixed base 8. When the hydraulic cylinder 82 is working, its hydraulic rod extends and retracts, causing the sliding seat 83 to move up and down within the fixed base 8, which in turn causes the straightening wheel 831 to move up and down, adjusting the straightening force in real time according to the actual condition of the copper rod 200.
[0028] When the copper rod 200 is inserted into the transmission groove of the fixed base 8, it passes between the roller 81 and the straightening roller 831. The synergistic effect of the roller 81 and the straightening roller 831 ensures that the copper rod 200 remains straight during transmission, avoiding quality problems caused by bending or twisting. In addition, the precise control of the hydraulic cylinder 82 ensures that the pressure applied by the straightening roller 831 is moderate, which will not damage the copper rod 200 and can effectively correct its shape, significantly improving the yield and product quality.
[0029] Among them, such as Figure 1 , Figure 2 and Figure 5 As shown, it also includes a limiting roller 9. At least one limiting roller 9 is rotatably mounted on the front side of the arc-shaped lead frame 5. The limiting roller 9 is arranged in the same direction as the guide roller 51, and there is a threading gap between the limiting roller and the guide roller. The main function of the limiting roller 9 is to further stabilize the transmission path of the copper rod 200, ensuring it remains in contact with the arc-shaped lead frame and preventing deviation or shaking during transmission. Guided by the limiting roller 9, the copper rod 200 is more stable when entering the arc-shaped lead frame 5, avoiding damage or deformation caused by path instability. Simultaneously, the synergistic effect of the limiting roller 9 and the guide roller 51 ensures smooth and precise transmission of the copper rod 200, improving the overall system stability and reliability.
[0030] In addition, such as Figure 1 , Figure 2 and Figure 5As shown, it also includes a guide seat 10, a cylinder 11, a connecting frame 12, and a pressing and rolling rod 121. The guide seat 10 is installed on the right side of the support seat 2. The connecting frame 12 is slidably provided inside the guide seat 10. The pressing and rolling rod 121 is rotatably provided on the left side of the connecting frame 12. The cylinder 11 is provided on the right side of the guide seat 10. The movable rod of the cylinder 11 is connected to one side of the connecting frame 12. The cylinder 11 drives the connecting frame 12 to move left and right on the guide seat 10, thereby driving the pressing and rolling rod 121 to move left and right laterally.
[0031] Specifically, when the movable rod of the cylinder 11 extends or retracts, it pushes or pulls the connecting frame 12 to move laterally along the slide rail inside the guide seat 10. This movement allows the pressure coiling rod 121 to precisely approach or move away from the copper rod mother coil 100, thereby providing stable pressure and support during the unwinding process. The design of the pressure coiling rod 121 ensures the smooth operation of the mother coil 100 during the unwinding process, avoiding problems such as wire breakage or deformation caused by the mother coil 100 being loose or too tight. At the same time, this adjustable pressure coiling mechanism enhances the adaptability of the equipment to mother coils 100 of different specifications and thicknesses, improving the flexibility and reliability of the overall system.
[0032] In a preferred embodiment: such as Figure 1 , Figure 2 and Figure 5 As shown, it also includes auxiliary rollers 13. Auxiliary rollers 13 are installed on the left and right sides and the left side of the rear of the support base 2. The multi-point setting of these auxiliary rollers 13 has an important role: by providing additional support and guidance at key positions, it ensures that the copper rod 200 remains stable throughout the transmission process and avoids direct contact between it and the support base 2, thereby preventing damage caused by friction or collision.
