Description

Technical Field

[0001] The present application relates to the technical field of wire tension monitoring, and in particular to an online tension balance monitoring device. Background Art

[0002] In the current cable production process, it is often necessary to detect the tension of the core wire in real time. Currently, the tension of the core wire is usually tested through a tension detection device. The device usually includes three rollers, and the middle roller is connected to a pressure sensor. The device is arranged as a whole during the transmission of the core wire. The cable is M-shaped and passes around the three rollers in turn. The pressure sensor detects the change of the core wire tension through the middle roller, but can only detect the tension of one core wire. In the cable production process, two or more core wires are often twisted into shape. During processing, the tension balance of the two core wires needs to be detected online in real time. For this reason, it is necessary to design a tension balance online monitoring device. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the present application provides an online tension balance monitoring device, including a load-bearing platform and a balance detection component rotatably arranged on the load-bearing platform, a plurality of first guide wheels and two second guide wheels are symmetrically arranged on both sides of the load-bearing platform, and two core wires are in an M shape and pass around the first guide wheel and the second guide wheel in turn, the two second guide wheels are connected by a connecting rod, and the connecting rod is transmission-connected to the balance detection component, and the balance detection component is used to detect the rotation angle of the connecting rod.

[0004] Preferably, the balance detection assembly includes a turntable and a sensor for detecting a rotation angle of the turntable, and the turntable is connected to the connecting rod.

[0005] Preferably, a pointer is provided on the turntable, and when the pointer rotates, it triggers the sensor to generate a displacement signal.

[0006] Preferably, it further comprises an information storage device, and the information storage device is electrically connected to the sensor.

[0007] Preferably, two first guide wheels are symmetrically arranged on both sides of the supporting platform.

[0008] As can be seen from the above, the following beneficial effects can be obtained by applying the present application: a balance detection component is rotatably arranged on the carrier platform, and a plurality of first guide wheels and two second guide wheels are symmetrically arranged on both sides of the carrier platform. The two core wires bypass the first guide wheel and the two second guide wheels respectively, so that the two core wires are in an M-shaped path. The two second guide wheels are connected by a connecting rod, and the connecting rod is connected to the balance detection component by transmission. The balance detection component is used to detect the balance displacement distance of the connecting rod, which is expressed as the rotation angle of the pointer on the turntable of the balance detection component. When the tension of the core wire on one side of the carrier platform is too large, the connecting rod will be pushed to the direction of the core wire on the other side to cause a balance displacement. When the connecting rod is displaced, the transmission device of the connecting rod is linked to the turntable to deflect at an angle. According to the detection and measurement of the rotation angle, the tension balance state of the two core wires can be monitored in real time, which is convenient for the subsequent real-time adjustment of the tension of the core wire, thereby ensuring production stability and improving the molding quality of the cable.

[0011] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0012] Example

[0013] In order to solve the above technical problems, this embodiment provides a tension balance online monitoring device, such as Figure 1As shown, it includes a carrier 10, on which a balance detection assembly 20 is rotatably arranged, and on both sides of the carrier 10, a plurality of first guide wheels 30 and two second guide wheels 40 are symmetrically arranged, and two core wires respectively bypass the first guide wheel 30 and the two second guide wheels 40, so that the two core wires are in an M-shaped path, and the two second guide wheels 40 are connected by a connecting rod 50, and the connecting rod 50 is connected to the balance detection assembly 20 by transmission, and the balance detection assembly is used to detect the balance displacement distance of the connecting rod, which is expressed as the rotation angle of the pointer on the turntable of the balance detection assembly. Then, when the tension of the core wire on one side of the carrier 10 is too large, the connecting rod 50 will be pushed to the direction of the core wire on the other side to cause a balance displacement, and when the connecting rod 50 is displaced, an angle deflection will occur, and according to the detection and measurement of the rotation angle, the tension balance state of the two core wires can be monitored in real time, and then the tension of the core wire is adjusted accordingly by manual or automatic means to ensure the tension balance of the core wire, thereby ensuring production stability and improving the molding quality of the cable.

[0014] Two first guide wheels 30 are symmetrically arranged on both sides of the carrier 10, and the core wire passes through the two first guide wheels 30 and a second guide wheel 40 to form an M-shaped moving path. The first guide wheel 30 is fixedly arranged and used to limit the core wire.

[0015] Specifically, the balance detection component 20 includes a turntable 21 and a sensor for detecting the rotation angle of the turntable 21. The turntable 21 is connected to the connecting rod 50. When the tension of the core wire on one side is too large and causes the connecting rod 50 to rotate, the connecting rod 50 drives the turntable 21 to rotate, and then the rotation angle or rotation position of the turntable 21 is detected by the sensor, thereby realizing real-time monitoring of the tension of the core wire.

[0016] Furthermore, a pointer 22 is provided on the turntable 21, and when the pointer 22 rotates, the sensor is triggered to generate a displacement or angle signal. In some embodiments, the turntable 21 is rotatably provided on the bearing platform 10 by means of a rotating shaft and a bearing, and then the connecting rod 50 can drive the turntable 21 to rotate. For example, the sensor can be an angle sensor connected to the rotating shaft, and then the rotation angle of the turntable 21 is detected. Alternatively, the sensor can be a position sensor, and the rotation angle of the turntable 21 can be determined by detecting the position of the pointer 22. The tension of the core wire can be adjusted accordingly in a manual or automatic manner, so as to facilitate the subsequent real-time adjustment of the tension of the core wire, ensure the balance of the tension of the core wire, and thus ensure production stability. Alternatively, a dial is provided on the bearing platform 10 in the direction of the pointer 22, and the angle of the pointer rotation can be determined manually by the dial, so that the on-site staff can intuitively determine the tension change trend of the core wire.

[0017] On the other hand, the present embodiment also includes an information storage device, which is electrically connected to the sensor. When the turntable 21 rotates to trigger the sensor to generate a displacement or angle signal, the sensor sends the signal to the information storage device. The information storage device generates a real-time coordinate curve by transcoding the signal to record the displacement change. The real-time coordinate curve can be saved in the information storage device, so that the tension change of the core wire during the production process can be analyzed later.

[0018] In summary, the present application scheme is to have a balance detection component rotatably arranged on the support platform, and a plurality of first guide wheels and two second guide wheels are symmetrically arranged on both sides of the support platform. The two core wires bypass the first guide wheel and the two second guide wheels respectively, so that the two core wires are in an M-shaped path. The two second guide wheels are connected by a connecting rod, and the connecting rod is connected to the balance detection component by transmission. The balance detection component is used to detect the balance displacement distance of the connecting rod, which is expressed as the rotation angle of the pointer on the turntable of the balance detection component. When the tension of the core wire on one side of the support platform is too large, the connecting rod will be pushed to the direction of the core wire on the other side to cause a balance displacement. When the connecting rod is displaced, the transmission device of the connecting rod is linked to the turntable to cause an angle deflection. According to the detection and measurement of the rotation angle, the tension balance state of the two core wires can be monitored in real time, which is convenient for the subsequent real-time adjustment of the tension of the core wire, thereby ensuring production stability and improving the molding quality of the cable.

[0019] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
