Description

Technical Field

[0001] The utility model relates to the technical field of frame stranding machines, in particular to a wire breakage detection device for frame stranding machines. Background Art

[0002] A stranding machine is a mechanical device that twists multiple individual conductors into a single strand of long, large-cross-sectional wire to meet the wire processing requirements. Individual conductors typically include aluminum / aluminum alloy wire, bare copper wire, steel-core aluminum stranded wire, fan-shaped conductors, and cross-linked compressed cable cores. Currently, stranding machines typically require a wire breakage detection device to inspect the stranded wires after stranding.

[0003] Existing Chinese patent publication number CN216484893U discloses a wire breakage detection device for a stranding machine. The key technical aspects of this device include: a gantry, a wire breakage detection mechanism mounted on the gantry, and a control mechanism. The wire breakage detection mechanism comprises two symmetrically arranged wire breakage detection components, each comprising a pressure sensor and an arc-shaped plate mounted on the pressure sensor head. The two arc-shaped plates together form a sleeve with a circular cross-section, the inner cavity of which is for passing stranded wire. The control mechanism is electrically connected to the pressure sensor and is used to control the stranding machine to stop based on the pressure sensor's signal. This application improves the product's yield rate.

[0004] The above-mentioned existing technical solution has the following defects: although the above-mentioned technical solution can improve the qualification rate of the product, in the above-mentioned technical solution, the arc plate and the pressure sensor are supported only by the reset spring, and there is no limiting mechanism to limit the reset spring. Since the reset spring is prone to shaking during use, its detection accuracy is easily reduced. Utility Model Content

Limit blocks 6 are provided on the top and bottom surfaces of the threaded cylinder 7, and one end of the limit blocks 6 extends into the inside of limit grooves 3 opened on both sides of the inner wall of the connecting cylinder 2. The wire processed by the bunching machine is conveyed between the arc-shaped plates 15. When the wire breaks, the wire will squeeze the arc-shaped plate 15, and the arc-shaped plate 15 will squeeze the return spring 16 between it and the pressure sensor 13. By using the return spring 16, the extrusion force can be transmitted to the pressure sensor 13. The pressure sensor 13 transmits the signal to the controller 9, and the controller 9 then transmits the signal to the audible and visual alarm 8. By using the audible and visual alarm 8, the surrounding staff can be reminded in time, so that the wire breakage can be detected. Among them, through the matching use of the plug rod 14 and the jack 12, the arc-shaped plate 15 can be effectively limited, so that the return spring 16 between the arc-shaped plate 15 and the pressure sensor 13 can be limited, preventing it from bouncing repeatedly, and facilitating maintaining the stability of the arc-shaped plate 15 during use.

[0030] In one embodiment, the arc-shaped plate 15 matches the clamping plate 11, which is convenient for the arc-shaped plate 15 to move in the clamping plate 11, so that the return spring 16 can be squeezed. By using the return spring 16, the extrusion force can be transmitted to the pressure sensor 13, which is convenient for detecting the wire breakage point of the wire.

[0031] In one embodiment, the plug rod 14 matches the jack 12, and the plug rod 14 can be inserted into the jack 12. Among them, through the matching use of the plug rod 14 and the jack 12, the arc-shaped plate 15 can be effectively limited, so that the return spring 16 between the arc-shaped plate 15 and the pressure sensor 13 can be limited, preventing it from bouncing repeatedly, and facilitating maintaining the stability of the arc-shaped plate 15 during use.

[0032] In one embodiment, the threaded cylinder 7 matches the through hole 10, which is convenient for the threaded cylinder 7 to move in the through hole 10, so that the position distance between the arc-shaped plates 15 in the clamping plate 11 can be adjusted.

[0033] In one embodiment, the limiting block 6 matches the limiting groove 3, facilitating the movement of the limiting block 6 in the limiting groove 3, thereby enabling the limiting of the threaded cylinder 7 and allowing the threaded cylinder 7 to move on the screw rod 5.

[0035] In one embodiment, the pressure sensor 13 is electrically connected to the controller 9, and the controller 9 is electrically connected to the sound and light alarm 8.

[0036] Working principle:

[0037] During use, the wire processed by the stranding machine is conveyed between the arc-shaped plates 15. When the wire breaks, the wire will squeeze the arc-shaped plates 15, and the arc-shaped plates 15 will squeeze the return spring 16 between them and the pressure sensor 13. By using the return spring 16, the extrusion force can be transmitted to the pressure sensor 13. The pressure sensor 13 transmits the signal to the controller 9, and the controller 9 then transmits the signal to the sound and light alarm 8. By using the sound and light alarm 8, the surrounding staff can be reminded in time, thereby enabling the detection of wire breakage. Among them, through the cooperation of the insertion rod 14 and the insertion hole 12, the arc-shaped plates 15 can be effectively limited, and thus the return spring 16 between the arc-shaped plates 15 and the pressure sensor 13 can be limited to prevent it from bouncing repeatedly, facilitating the maintenance of the stability of the arc-shaped plates 15 during use, thereby improving the detection accuracy. Among them, the motor 4 drives the screw rod 5 to rotate, and then the threaded cylinder 7 on the screw rod 5 is limited by the limiting block 6 and the limiting groove 3, enabling the threaded cylinder 7 to move on the screw rod 5. While moving, the threaded cylinder 7 drives the clamping plate 11 to move, causing the arc-shaped plates 15 in the clamping plate 11 to move, thereby automatically adjusting the position distance between the arc-shaped plates 15, facilitating the detection of wire breakage for wires with different large and small diameters, reducing the limitations during use, and being beneficial to expanding the application range of the present device.
