Description

Technical Field

[0001] This utility model relates to the technical field of cable processing, and in particular to a pre-twisting mechanism for a cable stranding machine. Background Technology

[0002] A cable stranding machine is a device used in the wire and cable industry to strand multiple single wires together according to certain rules. Its main purpose is to enhance the flexibility and mechanical strength of the cable and facilitate subsequent processing. During the cable laying process, it is necessary to fix the spool.

[0003] Existing wire feeding technology has some shortcomings in operation: First, existing wire feeding equipment cannot feed multiple spools of the same specification simultaneously, resulting in low production efficiency. Second, during the wire feeding process, the inner cavity of the spool cannot be effectively fixed, which can easily cause the spool to move relative to each other or fall out of its fixed position, causing the spool to move along with the cable, affecting the smoothness and quality of wire feeding. Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a pre-twisting mechanism for cable stranding machines. The turntable is started by rotating the component, and the turntable drives the support and the spool on it to rotate during the rotation, thereby performing preliminary stranding treatment on the wire to meet the characteristics of the preliminary process requirements of cable production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a pre-twisting mechanism for a cable stranding machine, comprising a protective housing, a turntable rotatably disposed on the front end face of the protective housing, support members evenly disposed on the front end face of the turntable, and a rotating assembly for rotating the turntable.

[0006] By adopting the above technical solution, the operator first fixes the spool on the support, and then starts the turntable by rotating the assembly. During the rotation of the turntable, the support and the spool on it are driven to rotate, thereby performing preliminary stranding of the wire to meet the preliminary process requirements of cable production.

[0007] As a preferred embodiment, each of the support components includes a protective sleeve fixedly connected to the turntable, a locking block evenly distributed around the outer periphery of the protective sleeve and slidably connected thereto, an adjusting wedge for adjusting the locking block, an adjusting rod rotatably and fixedly connected to the adjusting wedge, and an adjusting cylinder disposed at the end of the protective sleeve away from the end connected to the turntable. The inner wall of the adjusting cylinder is provided with an internal thread, and the outer periphery of the adjusting rod is provided with an external thread.

[0008] By adopting the above technical solution, the locking blocks are evenly arranged on the outside of the protective sleeve and slidably connected to the protective sleeve to accommodate spools of different diameters. The adjusting wedge is fixed to the adjusting rod by a rotatable connection, allowing the adjusting wedge to move axially according to the rotation of the adjusting rod, thereby adjusting the supporting outer diameter of the locking blocks. The adjusting cylinder is located at the end of the protective sleeve away from the turntable and has internal threads, while the adjusting rod has external threads on its outer circumference, allowing the adjusting rod to be threadedly connected to the adjusting cylinder and move axially. By rotating the adjusting rod, the adjusting wedge moves axially within the inner cavity of the protective sleeve, changing the position of the contact surface between the adjusting wedge and the inner side of the locking blocks, thus allowing the locking blocks to accommodate a wider range of spool inner diameters and providing a stable and reliable fixing function.

[0009] As a preferred embodiment, the adjusting wedge is configured as a trapezoidal column, and the outer periphery of the adjusting wedge is configured as a smooth arc surface by adopting the above-mentioned technical solution.

[0010] By employing the above technical solution, the adjusting wedge's function is to create different contact surfaces with the inner side of the locking block through axial movement, thereby driving the locking block to move horizontally. The adjusting rod drives the adjusting wedge to move axially within the protective sleeve cavity. The protective sleeve provides a stable axial movement trajectory for the adjusting wedge and the locking block. The locking block, in response to the movement of the adjusting wedge, moves horizontally by contacting different contact surfaces with it. Overall, this design, driven by the adjusting rod, enables the adjusting wedge to move axially, thereby changing the contact surface with the locking block and thus driving the locking block to move horizontally.

[0011] As a preferred embodiment, the outer side of the card block is uniformly provided with anti-slip protrusions, and the anti-slip protrusions are fixedly connected to the card block.

[0012] By adopting the above technical solution, the protective protrusions evenly distributed on the outer side not only improve the overall anti-slip performance of the structure but also effectively enhance the grip and safety of the locking block. Furthermore, the anti-slip protrusions fixedly connected to the locking block ensure a stable fit between the locking block and the connecting parts, further improving durability and service life.

[0013] As a preferred embodiment, the rotating assembly includes a rotating shaft connected to the turntable, a first gear connected to the rotating shaft, a transmission belt connected to the first gear, a second gear connected to the transmission belt, and a drive motor connected to the second gear. The output shaft of the drive motor is connected to the second gear, and the drive motor is configured as a reduction motor.

[0014] By adopting the above technical solution, the drive motor drives the second gear to rotate, and the second gear drives the transmission belt. Under the transmission of the transmission belt, the first gear rotates with the rotating shaft, thereby driving the turntable to rotate according to a predetermined path and speed.

[0015] As a preferred embodiment, to prevent the adjusting wedge from disengaging from the locking block, a limiting rod is also included, which is fixedly installed on the inner wall of the protective sleeve.

[0016] By adopting the above technical solution, the limiting rod is fixedly installed on the inner wall of the protective sleeve, and its main function is to prevent the adjusting wedge from separating from the locking block. Specifically, when the adjusting wedge moves within the protective sleeve, the limiting rod provides additional restraint to prevent the distance between the adjusting wedge and the locking block from becoming too large and causing them to detach.

[0018] 1. The turntable is mounted on the front face of the protective enclosure, making it easy to rotate via a rotating assembly;

[0019] 2. Support components are evenly distributed on the front end face of the turntable to fix the bobbin and keep it stable during rotation;

The turntable 2 is rotatably mounted on the front face of the protective housing 1, facilitating rotation via the rotating assembly. The support members 3 are evenly distributed on the front face of the turntable 2 to fix the bobbins, ensuring stability during rotation. The rotating assembly drives the turntable 2 to rotate, which in turn drives the support members 3 and the bobbins on them to rotate, achieving the initial stranding operation. In terms of working principle, the operator first fixes the bobbins to the support members 3, then starts the turntable 2 via the rotating assembly. During rotation, the turntable 2 drives the support members 3 and the bobbins on them to rotate, thus performing preliminary stranding of the wire to meet the initial process requirements of cable production.

[0035] Please refer to details. Figure 4 The adjusting wedge 33 is a trapezoidal column with a smooth arc surface on its outer periphery.
