Description

Technical Field

[0001] This utility model relates to the field of cable-making machine technology, specifically to a tension balancing device for cable-making machines. Background Technology

[0002] Cable forming machines are key equipment in the wire and cable industry for stranding multiple insulated cores into cables. During the stranding process, the tension balance supplied to the cores by each unwinding unit is crucial. Uneven tension can lead to loose core structure, uneven arrangement, poor roundness, and even problems such as core arching and breakage, severely affecting the performance and quality of the final product. Currently, some cable forming machines use mechanical friction discs or manual adjustment brakes to control the unwinding tension. This method has low adjustment accuracy, slow response, and cannot be dynamically adjusted according to real-time operating conditions, making it difficult to ensure consistent tension across all cores. Therefore, this invention proposes a tension balancing device for cable forming machines to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a tension balancing device for cable-making machines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tension balancing device for a cable forming machine, comprising a mounting plate and a controller. A support plate is fixedly mounted on the mounting plate, and an unwinding roller is rotatably mounted on the support plate. The unwinding roller is connected to a magnetic powder brake. A support base is also fixedly mounted on the mounting plate, and a detection component for detecting cable tension is provided on the support base. The detection component is electrically connected to the controller, and the controller is electrically connected to the magnetic powder brake. The controller is used to adjust the braking torque of the magnetic powder brake according to the detection signal from the detection component.

[0005] Preferably, the detection component includes a support roller, a sliding block, a sliding groove, a connecting plate, and a pressure sensor. A U-shaped groove is formed on the support base, and sliding grooves are formed on both side walls of the U-shaped groove. The sliding block is slidably disposed in the sliding groove, and the support roller is rotatably connected between the two sliding blocks.

[0006] Preferably, a connecting plate is fixedly connected between the two sliding blocks, and a protrusion is provided at the lower end of the connecting plate. The pressure sensor is disposed in the U-shaped groove of the support base and located below the protrusion.

[0007] Preferably, the pressure sensor is electrically connected to the signal input terminal of the controller, and is used to convert the detected pressure signal into an electrical signal and transmit it to the controller.

[0008] Preferably, the magnetic powder brake is electrically connected to the output terminal of the controller, and the controller is used to generate and output a corresponding control signal to the magnetic powder brake based on the received pressure electrical signal, so as to dynamically adjust the rotational resistance of the unwinding roller.

[0009] Preferably, the axis of the support roller is arranged parallel to the axis of the unwinding roller.

[0010] Preferably, the magnetic powder brake is fixedly installed on the outer side wall of the support plate via a flange, and the output shaft of the magnetic powder brake is coaxially and fixedly connected to the end of the unwinding roller.

[0011] Preferably, the support plate is fixedly connected to the mounting plate by welding, and the support plate is provided with bearing mounting holes adapted to the unwinding roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a detection component, changes in cable tension can directly drive the sliding block to slide along the sliding groove. The pressure sensor, triggered by the protrusion of the connecting plate, enables real-time tension detection. Combined with the linkage between the controller and the magnetic powder brake, the braking force of the unwinding roller can be quickly and dynamically adjusted, solving the problems of slow response and low adjustment accuracy in existing devices, and effectively preventing cable breakage, slack, or entanglement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a tension balancing device for a cable forming machine, including a mounting plate 1 and a support plate 2 fixedly connected to the mounting plate 1 by welding. The weld is ground to ensure the connection strength. The support plate 2 is provided with bearing mounting holes adapted to the unwinding roller 3. The holes are filled with deep groove ball bearings as used in the prior art. The two ends of the unwinding roller 3 are rotatably mounted on the support plate 2 through the bearings, so that the unwinding roller 3 can rotate smoothly to realize the continuous unwinding of the cable.

[0022] like Figure 2 As shown, the magnetic powder brake 4 is fixedly installed on the outer side wall of the support plate 2 via a flange. A sealing gasket is provided between the flange and the support plate 2 to improve the installation sealing. The output shaft of the magnetic powder brake 4 is coaxially fixed to the end of the unwinding roller 3 via a key connection, ensuring that the braking force of the magnetic powder brake 4 can be accurately transmitted to the unwinding roller 3, thereby controlling the unwinding speed of the unwinding roller 3.

[0023] like Figure 2 as well as Figure 3 As shown, the support base 5 is fixedly installed on the mounting plate 1 by bolts. The U-shaped groove opened on the support base 5 provides installation space for the detection component 6. The pressure sensor 65 is installed at the bottom of the U-shaped groove by bolts to ensure the stability of the installation of the pressure sensor 65.

[0024] like Figure 3 as well as Figure 4As shown, the sliding groove 63 of the detection component 6 is directly formed on both side walls of the U-shaped groove. The side walls of the sliding block 62 are tightly fitted with the inner wall of the sliding groove 63, and a graphite lubrication layer is provided between the sliding block 62 and the sliding groove 63. Using graphite lubrication material in the prior art can effectively reduce the frictional resistance of the sliding block 62 during sliding and improve the sliding response speed. The support roller 61 is rotatably connected between the two sliding blocks 62 through a rotating shaft. The support roller 61 is made of aluminum alloy, which combines lightness and wear resistance. Its outer peripheral wall is integrally formed with anti-slip texture, which can increase the friction between the cable and the cable and prevent the cable from slipping on the support roller 61.

[0025] The connecting plate 64 is welded between the two sliding blocks 62 to ensure that the sliding blocks 62 and the connecting plate 64 move synchronously. The rectangular protrusion at the lower end of the connecting plate 64 is in direct contact with the sensing end of the pressure sensor 65. The hemispherical structure enables the pressure to be concentrated and transmitted, improving the accuracy of pressure detection.

[0026] The pressure sensor 65 is electrically connected to the controller via a wire, and the magnetic powder brake 4 is also electrically connected to the controller via a wire. The controller adopts the existing PLC controller and is installed on the side of the mounting plate 1 with a reserved mounting position. The controller can receive the pressure signal transmitted by the pressure sensor 65 in real time and quickly issue control commands according to the preset tension threshold to adjust the braking force of the magnetic powder brake 4 and realize the dynamic balance control of cable tension.

[0027] In actual use, the support plate 2 fixed on the mounting plate 1 provides rotational support for the unwinding roller 3. After the cable is released from the unwinding roller 3, it passes around the support roller 61. When the cable tension changes, it will drive the support roller 61 and the sliding block 62 rotatably connected to it to slide along the sliding groove 63. The sliding block 62 synchronously drives the fixedly connected connecting plate 64 to move, so that the protrusion at the lower end of the connecting plate 64 generates different pressures on the pressure sensor 65 installed in the U-shaped groove below. The pressure sensor 65 transmits the detected pressure signal to the controller. The controller adjusts the braking force of the magnetic powder brake 4 connected to the unwinding roller 3 in real time according to the signal, thereby stabilizing the unwinding speed of the unwinding roller 3 and realizing the dynamic balance of cable tension. This effectively prevents the cable from being pulled apart due to excessive tension or from becoming loose and tangled due to insufficient tension, ensuring the continuity and stability of the cabling process, and improving the structural accuracy and quality consistency of the cabling products.
