Description

Technical Field

[0001] This utility model relates to the technical field of wire and cable traction equipment, specifically a traction mechanism for wire and cable production. Background Technology

[0002] Wires and cables are essential electrical materials used to transmit electrical energy or signals. They consist of one or more conductors (usually copper or aluminum) and their insulation and protective layers. They play a crucial role in various applications, from household electricity to industrial power transmission and complex communication networks. Depending on their usage environment and function, wires and cables can be classified into several types, such as power cables, control cables, and communication cables, and must meet relevant standards and specifications to ensure safety and reliability.

[0003] In the production process of wires and cables, traction equipment plays a crucial role. It is mainly used to pull the cable through a series of processing equipment, such as extruders and armoring machines, to complete processes such as insulation layer coating, shielding layer production, sheath layer wrapping, and armoring. Traction equipment ensures the stable movement of the cable on the production line, so that each layer of material can be evenly and tightly wrapped around the outside of the conductor, which is crucial to ensuring the quality of the cable production process.

[0004] In existing wire and cable traction equipment, when encountering a jammed wire or cable, the only option is to manually shut down the equipment. Although this setting meets the usage requirements to some extent, this method not only has a long response time, which can easily lead to increased damage to the equipment and cables, but may also cause production accidents or quality problems due to untimely handling. This manual intervention method is inefficient and cannot meet the requirements of automated and intelligent production lines for rapid response and precise control. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing wire and cable traction equipment, which typically only allows for manual shutdown when encountering jammed wires and cables. This not only results in a long response time, potentially exacerbating damage to the equipment and cables, but also may lead to production accidents or quality problems due to untimely handling. Therefore, this invention proposes a traction mechanism for wire and cable production. This traction mechanism achieves intelligent protection through a self-disconnecting transmission mechanism. When the cable jams, the automatic disengagement of the locking ball and the serrations immediately cuts off power transmission, effectively preventing equipment overload damage and cable breakage, significantly improving safety and reliability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a traction mechanism for wire and cable production, including a frame mechanism. A first traction wheel set is fixedly installed inside the frame mechanism. An adjustment mechanism is fixedly installed on the top of the frame mechanism. A second traction wheel set is movably installed inside the frame mechanism, with the second traction wheel set positioned on top of the first traction wheel set. The second traction wheel set is fixedly connected to the bottom of the adjustment mechanism. A drive motor is fixedly installed inside the frame mechanism. One side of the output shaft of the drive motor is fixedly connected to a self-disconnecting transmission mechanism via a coupling. The self-disconnecting transmission mechanism is fixedly connected to one side of one set of guide wheels inside the first traction wheel set.

[0007] Furthermore, the self-disconnecting transmission mechanism includes a drive rod and a driven rod. The drive rod is fixedly connected to one side of the output shaft of the drive motor. The driven rod is fixedly connected to one side of one set of guide wheels inside the first traction wheel set. One side of the driven rod is provided with several protruding teeth. One side of the drive rod is fixedly connected to a mounting rod. One side of the mounting rod is fixedly mounted with a mounting plate. The driven rod is rotatably mounted on one side of the mounting rod. Several locking balls are movably mounted inside the mounting plate. An adjusting plate is slidably mounted on the outer wall of the mounting rod. Several second springs are fixedly mounted on one side of the adjusting plate. The second springs are located on one side of the locking balls.

[0008] Furthermore, a telescopic component is fixedly installed on one side of the drive rod, and the telescopic shaft of the telescopic component is fixedly connected to one side of the adjustment disc.

[0009] Furthermore, the frame mechanism includes a mounting base, the first traction wheel assembly is fixedly mounted on the top of the mounting base, a C-shaped frame is fixedly mounted on one side of the mounting base, the adjustment mechanism is fixedly mounted on the top of the C-shaped frame, and a rubber pad is fixedly mounted on the bottom of the mounting base.

[0010] Furthermore, the adjustment mechanism includes a mounting frame and a mounting block. The mounting frame is fixedly mounted on the top of the C-shaped frame. Limiting grooves are provided on both the left and right sides of the mounting frame. Protrusions are fixedly mounted on both the left and right sides of the mounting block. The protrusions are slidably mounted inside the limiting grooves. A through-shaft type lead screw motor is fixedly mounted on the top of the mounting frame. An adjusting lead screw is internally threaded into the through-shaft type lead screw motor. A first spring is fixedly mounted on the bottom of the adjusting lead screw. The first spring is fixedly connected to the top of the mounting block. A connecting rod is fixedly connected to the bottom of the mounting block. The connecting rod passes through the C-shaped frame and is fixedly connected to the top of the second traction wheel assembly.

[0011] Furthermore, a number of limiting rods are slidably installed on the top of the C-shaped frame, and the number of limiting rods are fixedly installed on the top of the second traction wheel set.

[0012] Furthermore, the mounting base and the rubber pad have several mounting holes inside.

[0013] The present invention proposes a traction mechanism for wire and cable production, which has the following advantages: it realizes intelligent protection function through self-disconnection transmission mechanism. When the cable is jammed, the automatic disengagement of the locking ball and the tooth can cut off the power transmission in time, effectively avoid equipment overload damage and cable breakage, and significantly improve safety and reliability. The adjustment mechanism drives the second traction wheel set to move through the through-shaft lead screw motor. Combined with the first spring buffer design, it can flexibly adapt to cables of different diameters, taking into account both versatility and precise clamping force. The combination of rubber pads and mounting holes in the frame structure enhances the stability of equipment operation, reduces the impact of vibration on machining accuracy, and facilitates quick and easy installation. The threshold adjustment function of the telescopic component and the second spring allows users to dynamically adjust the torque threshold at which the drive rod and driven rod disengage from the transmission relationship according to the actual working conditions, further optimizing the response sensitivity and protection performance of the equipment under different loads, and achieving overall synergistic optimization of efficient traction, intelligent protection and convenient adjustment.

On one side, a driven rod 602 is fixedly connected to one side of one of the guide wheels inside the first traction wheel set 2. A plurality of protruding teeth 603 are provided on one side of the driven rod 602. A mounting rod 604 is fixedly connected to one side of the drive rod 601.

A plurality of second springs 608 are fixedly mounted on one side of the adjusting plate 607. The second springs 608 are located on one side of the locking balls 606. A telescopic component 609 is fixedly mounted on one side of the drive rod 601. The telescopic shaft of the telescopic component 609 is fixedly connected to one side of the adjusting plate 607. The frame mechanism 1 includes a mounting base 101, a first traction wheel set 2 fixedly mounted on the top of the mounting base 101, a C-shaped frame 102 fixedly mounted on one side of the mounting base 101, an adjustment mechanism 3 fixedly mounted on the top of the C-shaped frame 102, a rubber pad 104 fixedly mounted on the bottom of the mounting base 101, and several limiting rods 103 slidably mounted on the top of the C-shaped frame 102. Several limiting rods 103 are fixedly mounted on the top of the second traction wheel set 4. Several mounting holes 105 are provided inside the mounting base 101 and the rubber pad 104. The rubber pad 104 increases the friction between the frame mechanism 1 and the mounting platform and absorbs the vibration generated during equipment operation. The mounting holes 105 facilitate the user to fix the equipment to the mounting surface with screws or pins. The several limiting rods 103 restrict the movement direction of the second traction wheel set 4. The adjustment mechanism 3 includes a mounting frame 301 and a mounting block 302. The mounting frame 301 is fixedly mounted on the top of the C-shaped frame 102. Limiting grooves 303 are provided on both the left and right sides of the mounting frame 301. Protrusions 304 are fixedly mounted on both the left and right sides of the mounting block 302. The protrusions 304 are slidably mounted inside the limiting grooves 303. A through-shaft type lead screw motor 305 is fixedly mounted on the top of the mounting frame 301.

The connecting rod 308 passes through the C-shaped frame 102 and is fixedly connected to the top of the second traction wheel group 4. When the through-shaft screw motor 305 runs, it can drive the adjusting screw 306 to move up and down inside the mounting frame 301, and then drive the second traction wheel group 4 to move through the first spring 307, the mounting block 302, and the connecting rod 308, thereby changing the distance between the first traction wheel group 2 and the second traction wheel group 4, so that the first traction wheel group 2 and the second traction wheel group 4 can clamp cables of different sizes.

[0021] The traction mechanism for wire and cable production of this utility model realizes intelligent protection function through the self-disconnection transmission mechanism 6. When the cable is jammed, the automatic disengagement of the locking ball 606 and the convex tooth 603 can cut off the power transmission in time, effectively avoiding equipment overload damage and cable breakage, and significantly improving safety and reliability. The adjustment mechanism 3 drives the second traction wheel group 4 to move through the through-shaft lead screw motor 305. Combined with the buffer design of the first spring 307, it can flexibly adapt to cables of different diameters, taking into account both versatility and precise clamping force. The combination design of rubber pad 104 and mounting hole 105 in frame mechanism 1 enhances the stability of equipment operation, reduces the impact of vibration on processing accuracy, and facilitates quick and easy installation. The threshold adjustment function of the telescopic component 609 and the second spring 608 allows users to dynamically adjust the torque threshold at which the drive rod 601 and the driven rod 602 disengage from the transmission relationship according to the actual working conditions, further optimizing the response sensitivity and protection performance of the equipment under different loads, and achieving overall synergistic optimization of efficient traction, intelligent protection and convenient adjustment.

[0022] Specifically, the cable is placed between the first traction wheel set 2 and the second traction wheel set 4. The drive motor 5 drives one of the guide wheels inside the first traction wheel set 2 to rotate through the self-disconnecting transmission mechanism 6, thereby pulling the cable to move. During this process, the locking ball 606 and the tooth 603 mesh with each other, so that the drive rod 601 can drive the driven rod 602 to rotate synchronously. When the cable gets stuck, the torque of the driven rod 602 will increase, forcing the locking ball 606 to overcome the elastic force of the second spring 608 and move away from the tooth 603, so that the locking ball 606 and the tooth 603 disengage, thereby disengaging the drive rod 601 and the driven rod 602 from the transmission relationship. This achieves the purpose of preventing the first traction wheel set 2 from outputting force to the cable. At the same time, the telescopic component 609 drives the adjusting plate 607 to move on the outer wall of the mounting rod 604, changing the squeezing force of the second spring 608 on the locking ball 606, which can change the threshold of the torque that disengages the drive rod 601 and the driven rod 602 from the transmission relationship.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
