[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] like Figure 1 , Figure 2As shown, the utility model discloses an anti-fracture buffer release device for copper wire stretching, comprising a frame 1 and guide wheels 2 arranged at both ends of the frame 1, a vertical upright plate 3 is arranged on the frame 1 between the guide wheels 2, a horizontal plate 4 is arranged on the top of the upright plate 3, a wheel seat 5 is arranged on the lower surface of the horizontal plate 4, a tension sensor 8 is arranged between the wheel seat 5 and the horizontal plate 4, a tension wheel 6 is arranged on the wheel seat 5, and the tension wheel 6 is located above between the guide wheels 2; the wheel seat 5 comprises a mounting top plate 51 and two mounting side plates 52, the mounting side plates 52 are fixed to both sides of the mounting top plate 51, an annular arc-shaped inner groove 23 is arranged on the circumferential side wall of the tension wheel 6, and the tension wheel 6 is divided into two parts by the middle of the axial direction, The first wheel body 13 and the second wheel body 14 are respectively connected to form a tensioning wheel 6. The first wheel body 13 is connected to the first shaft body 15 through a bearing 17. The first shaft body 15 is fixed on a mounting side plate 52. The second wheel body 14 is connected to the second shaft body 16 through a bearing 17. The second shaft body 16 is arranged on another mounting side plate 52. A horizontal through hole is arranged on the mounting side plate 52 corresponding to the second shaft body 16. The second shaft body 16 is slidably connected in the horizontal through hole. A telescopic mechanism is arranged on the mounting side plate 52. The telescopic mechanism drives the second shaft body 16 to slide in the horizontal through hole. It also includes a controller 12. The controller 12 is electrically connected to the telescopic mechanism and the tension sensor 8.

[0016] The copper wire 11 passes through the bottom of one of the guide wheels 2, then passes through the top of the tensioning wheel 6, and then passes through the bottom of the other guide wheel 2 to achieve the tensioning of the copper wire 11. Figure 1As shown, during the stretching process of the copper wire 11, tension acts on the tension wheel 6. Since the wheel seat 5 of the tension wheel 6 is arranged on the tension sensor 8, a certain tension will be generated on the tension sensor 8. The tension sensor 8 is an existing commercially available product and is a prior art, so it will not be described in detail. The tension signal generated by the tension sensor 8 is transmitted to the controller 12, which is also an existing commercially available product. The tension limit value can be set in the controller 12. When the tension value transmitted from the tension sensor 8 to the controller 12 reaches the set tension limit value, the controller 12 controls the telescopic mechanism to operate. The telescopic mechanism contracts, which will drive the second shaft 16 to move away from the first shaft 15. At this time, the first wheel body 13 and the second wheel body 14 will be separated, and a gap will be generated between the two. The copper wire on the tension wheel 6 will slide down from the gap, so that the copper wire 11 between the two guide wheels 2 is in a relaxed state, releasing the tension between the copper wires 11 and avoiding the copper wire 11 from breaking. Controller 12, at this time, controller 12 can control the equipment to shut down, and the operator can check the equipment problem and restart it after eliminating it. When the telescopic mechanism is extended, the first wheel body 13 and the second wheel body 14 are docked to form a complete tensioning wheel 6, and the copper wire 11 is located in the arc-shaped inner groove 23 of the tensioning wheel 6. The conveying process of the copper wire 11 is stable and reliable. Since the first shaft body 15 and the second shaft body 16 are both non-rotating, the first wheel body 13 and the second wheel body 14 are both set on the first shaft body 15 and the second shaft body 16 through the bearing 17, and the tensioning wheel 6 can rotate freely to ensure the reliability of transportation. The central axes of the first shaft body 15 and the second shaft body 16 coincide.

[0017] The telescopic mechanism includes a mounting frame 18 arranged on the mounting side plate 52, a motor 19 is fixedly arranged on the mounting frame 18, a fixed screw rod 20 is arranged at the output end of the motor 19, the motor 19 drives the screw rod 20 to rotate, a concave screw hole 21 is arranged at the end of the second shaft body 16, the screw rod 20 is matched and connected with the screw hole 21, and the controller 12 is connected with the motor 19 by electrical signals. A guide protrusion 22 is arranged on the side wall of the second shaft body 16, and a concave structure is arranged on the inner side wall of the horizontal through hole, the guide protrusion 22 is located inside the concave structure, and the guide protrusion 22 cooperates with the concave structure of the horizontal through hole to limit the rotation of the second shaft body 16. The combination of the motor 19 and the screw rod 20 is adopted, the motor 19 drives the screw rod 20 to rotate, and the screw rod 20 cooperates with the screw hole 21 on the second shaft body 16, and the rotation of the screw rod 20 can cause the second shaft body 16 to move in the horizontal through hole. Of course, the distance between the two mounting side plates 52 is greater than the axial thickness of the tension wheel 6, and the second wheel body 14 has a certain displacement space in the axial direction. Therefore, when the second shaft body 16 moves outward under the action of the screw rod 20, it drives the second wheel body 14 to move, so that a gap is generated between the second wheel body 14 and the first wheel body 13. The motor 19 can be a servo motor, which has higher control accuracy.

[0018] An arc-shaped protrusion 24 is provided at the center of the first wheel body 13, and an arc-shaped concave is provided at the center of the second wheel body 14, and the arc-shaped protrusion 24 cooperates with the arc-shaped concave for positioning. An arc-shaped protrusion 24 and an arc-shaped concave are provided at the center of the first wheel body 13 and the second wheel body 14, and the cooperation and positioning of the two can make the cooperation of the first wheel body 13 and the second wheel body 14 more stable. The arc-shaped protrusion 24 and the arc-shaped concave can adopt an elliptical arc surface structure to ensure that there will be no relative displacement between the first wheel body 13 and the second wheel body 14 after cooperation and positioning, so as to improve reliability.

[0019] A connecting hole is provided on the mounting top plate 51, and a connecting rod 7 is slidably provided in the connecting hole in the vertical direction.

[0020] A connection hole is set on the top of the mounting plate, and the wheel seat 5 is slidably connected to the connection hole through the connecting rod 7 and connected through the spring 9. In the actual working process, the tension of the copper wire 11 can be adjusted by the spring 9 to keep the wheel seat 5 able to have a certain displacement to maintain the stability of the copper wire 11. When the tension of the copper wire 11 reaches the set extreme value, the tension wheel 6 will be released.

[0021] A guide hole is provided on the mounting top plate 51 at the side of the connecting hole, and a guide rod 10 is provided in the guide hole, and the lower end of the guide rod 10 is fixedly connected to the wheel seat 5. The design of the guide hole and the guide rod 10 enables the wheel seat 5 to only realize lifting movement and will not deflect around the connecting rod, so that the guidance of the copper wire 11 is stable and the transportation of the copper wire 11 is more reliable.
