DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0030] In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0031] Please refer to Figs. 1-3As shown, this embodiment provides an automatic stop stranding device 10 for detecting wire breakage and controlling shutdown during the stranding process of the conductor 20. The device 10 includes a wire feeding machine 100, a wire bundling machine 110, a wire separating reel 120, a signal component 130, and a controller 140. The wire feeding machine 100 feeds the conductor 20, the wire bundling machine 110 strands the conductor 20, and the wire separating reel 120 has several wire-passing holes 120a. After the conductor 20 is fed by the wire feeding machine 100, each conductor 20 is individually stranded. The wires pass through one of the through holes 120a of the wire distribution plate 120, and then enter the wire bundling machine 110 for twisting and output, ultimately forming a copper core conductor composed of multiple parallel copper wires; furthermore, the signal component 130 is arranged below all the wires 20 for contacting the broken wires 20; the controller 140 is electrically connected to the wire bundling machine 110 and the signal component 130. When the signal component 130 detects that at least one wire 20 is broken and makes contact with it, the controller 140 receives the signal and triggers the wire bundling machine 110 to stop.

[0032] Understandably, this embodiment uses a signal component positioned below all the wires to simultaneously intercept all broken wires during stranding. When any one or more wires break and droop, they will come into contact with the signal component, triggering a stop signal. This design not only simplifies the structure and reduces the number of sensors and wiring complexity, but also significantly reduces equipment costs. This significantly optimizes the equipment structure and reduces production costs, making it suitable for the efficient control requirements of large-scale cable stranding production.

[0033] In this embodiment, the signal component 130 is positioned below the stranded wires 20, allowing it to contact any broken wire 20. A contact signal is transmitted to the controller 140 via an electrical connection, which then cuts off the power supply to the wire bundling machine 110, terminating the stranding process. This mechanism ensures that the wires 20 between the wire feeding machine 100 and the wire bundling machine 110 are stopped, facilitating timely replacement of broken wires by operators and preventing quality defects in the copper conductors caused by broken wires.

[0034] like Fig. 2 As shown, in a preferred embodiment, the signal component 130 includes a conductive wire 131, a grounding wire 132, and a first sensor 133. The grounding wire 132 connects the conductive wire 131 to the ground, and the first sensor 133 is electrically connected to the controller 140. When at least one broken wire 20 comes into contact with the energized conductive wire 131, a closed loop is formed. The sensor 133 detects the current change and sends a signal to the controller 140, triggering the wire-binding machine 110 to stop. In this solution, the conductive sensor 133 detects the broken wire by monitoring the current flow of the conductive wire 131, resulting in fast response and high reliability.

[0035] like Fig. 3As shown, in another preferred embodiment, the signal assembly 130 comprises a contact wire 134 and a second sensor 135, the contact wire 134 is not conductive, when at least one broken wire 20 hits the contact wire 134, the mechanical vibration generated is captured by the second sensor 135, the second sensor 135 sends a trigger signal to the controller 140 immediately, and the controller 140 controls the stranding machine 110 to stop. This scheme uses vibration frequency to detect broken wire, which is suitable for non-conductive wire 20 scenarios, and has strong anti-electromagnetic interference ability.

[0036] Preferably, the first sensor 133 comprises a conductive sensor, and the second sensor 135 comprises a vibration sensor 135; it can be understood that in some previous embodiments, the first sensor 133 can be set as a conductive sensor, and in some later embodiments, the second sensor 135 can also be set as a vibration sensor; optionally, other types of sensors (such as gravity sensors) can also be adapted to the device, which is selected according to the characteristics of the wire 20 and the working condition requirements; it can be understood that since the signal assembly 130 adopts conductive sensing or vibration sensing mechanism, its detection sensitivity is high, and the response speed is fast, which can ensure that the machine stops immediately at the moment of broken wire, avoiding the quality defects of stranding caused by broken wire.

[0037] Preferably, the device further comprises a fixed frame 150 installed on the side of the distribution disc 120 away from the stranding machine 110, for supporting the conductive wire 131 or the contact wire 134. The fixed frame 150 ensures that the conductive wire 131 or the contact wire 134 is kept tensioned within a set length, and forms an area for effectively intercepting the broken wire 20. The first sensor 133 or the second sensor 135 can be installed on the conductive wire 131 or the fixed frame 150, which needs to meet the high-efficiency detection requirements of the signal.

[0038] Preferably, the first sensor 133 is installed on the conductive wire 131, or the first sensor 133 is installed on the fixed frame 150, or the second sensor 135 is installed on the conductive wire 131, or the second sensor 135 is installed on the fixed frame 150, this embodiment realizes the use of the first sensor 133 and / or the second sensor 135 by installing the first sensor 133 at a position that can sense the conductive wire 131, or by installing the second sensor 135 at a position that can sense the contact wire 134.

[0039] Preferably, the conductive wire 131 or the contact wire 134 is recessed to form an arc relative to the wire 20 between the fixed frames 150; the advantage of this structure design is that by arranging the conductive wire 131 in an arc shape between the fixed frames 150, it avoids the broken wire 20 from falling due to excessive straightening. This arc structure improves the capture rate of the drooping wire 20, and ensures the reliability of the signal trigger.

[0040] Preferably, the straight-line distance L1 between the conductive wire 131 or the contact wire 134 and the wire distributor 120 is at least greater than 40mm. The purpose of this design is to avoid the conductive wire 131 or the contact wire 134 being too close to the wire distributor 120, which would cause the wire 20 to break after it passes through the wire hole 120a. This would result in the inner wall of the wire hole 120a of the wire distributor 120 providing partial support to the wire 20, preventing the broken wire 20 from contacting the conductive wire 131 or the contact wire 134, thereby avoiding the inability to generate a signal to the first sensor 133 or the second sensor 135.

[0041] Preferably, the straight-line distance between the conductive wire 131 or the contact wire 134 and the uncontacted wire 20 is at least greater than 20mm, so as to avoid abnormal swinging of the wire 20 during the production process from touching the conductive wire 131 or the contact wire 134.

[0042] Preferably, it also includes an alarm, the signal component includes a conductive wire or a contact wire, the alarm is electrically connected to the controller, and / or the alarm is electrically connected to the conductive wire or the contact wire.

[0043] Optionally, in this embodiment, the conductive wire 131 is set as a bare metal wire.

[0044] Preferably, the device also includes an alarm 160, which is electrically connected to the controller 140 and / or electrically connected to the conductive wire 131. It is understood that in some embodiments, by setting the alarm 160, when the wire 20 breaks, the controller 140 activates the alarm 160, allowing the operator to promptly detect equipment problems and perform timely maintenance to ensure cable production efficiency. Optionally, in other embodiments, the alarm 160 can also be electrically connected to the conductive wire 131. When the conductive wire 131 contacts the wire 20, the wire 20 connects to the conductive wire 131, and the alarm 160 is electrically connected to the conductive wire 131. By connecting the power supply to the alarm 160, the alarm 160 can begin to alarm. In other embodiments, the alarm 160 can also be electrically connected to the first sensor 133 or the second sensor 135. When the conductive wire 131 or the contact wire 134 comes into contact with the wire 20, the wire 20 and the contact wire 134 are connected and vibrate, thereby generating a vibration signal sent to the controller 140. Alternatively, the wire 20 and the conductive wire 131 are connected and form a circuit, generating current and thus generating an electrical signal sent to the controller. The alarm 160 is powered on by the electrical connection to the first sensor 133 or the second sensor 135, and the alarm 160 can begin to alarm.

[0045] In conclusion, the utility model provides a kind of automatic stoppage wire stranding equipment, by signal component is located below all conductor, can intercept all broken conductor in stranding simultaneously, when any one or more conductor is broken and droops, all will contact with signal component, trigger stoppage signal;The design not only simplifies structure, reduces the number of sensor and wiring complexity, also greatly reduces equipment cost;So significantly optimize equipment structure, and reduce production cost, applicable to the efficient management and control demand of large-scale cable stranding production.
