Description

Technical Field

[0001] This utility model relates to the field of cable tension adjustment technology, specifically to a cable tension adjustment device. Background Technology

[0002] Cables, also known as wires, are conductors used to transmit electrical energy or signals and are widely used in power, communications, construction, and other fields. During cable processing, the tension of the cable is adjusted using a cable tensioning device to ensure stable tension during winding, pulling, or unwinding, preventing tangled winding due to excessive looseness or damage due to excessive tightness.

[0003] However, existing cable tensioning devices lack inlet and outlet limit components, relying solely on connections with upstream and downstream equipment for cable guidance and positioning. This results in an excessively long tension adjustment range, leading to delayed tension control response and insufficient adjustment precision. Consequently, real-time cable tension control is affected, making it difficult to meet the demands of high-precision cable processing. Therefore, this invention proposes a cable tensioning device with inlet and outlet limit components, enabling real-time tension adjustment. Summary of the Invention

[0004] This utility model provides a cable tension adjustment device, which solves the technical problems of existing tension adjustment response lag and insufficient accuracy, and inability to control cable tension in real time, by using a tension sensor, an inlet limit component and an outlet limit component.

[0005] The objective of this utility model is achieved through the following means: A cable tension adjustment device includes a bracket, a tension adjustment component mounted on the bracket, and a plurality of guide wheels. A tension sensor cooperating with the tension adjustment component is provided between the guide wheels. An inlet limit component and an outlet limit component cooperating with the tension adjustment component and the guide wheels are respectively provided at both ends of the bracket.

[0006] Furthermore, both the inlet and outlet limiting components are composed of several detachable horizontal and vertical guide rollers, which are perpendicular to each other.

[0007] Furthermore, both ends of the bracket are provided with fixed frames, and the fixed frames and the bracket are respectively provided with sliding grooves that cooperate with the horizontal guide roller and the vertical guide roller. One end of the horizontal guide roller and the vertical guide roller is provided with a sliding rod and a locking block that cooperate with the sliding groove.

[0008] Furthermore, the tension adjustment assembly includes a fixed pulley, a movable pulley, and a sliding frame. The sliding frame slides back and forth on the support via a driving component. The fixed pulley and the movable pulley are rotatably mounted on the support and the sliding frame, respectively.

[0009] Furthermore, the fixed pulley and the movable pulley are each arranged in a linear array along the axial direction with several grooves.

[0010] Furthermore, the driving component is a cylinder, and the sliding frame and the bracket are respectively provided with a connecting component and a pressure regulating valve that cooperate with the cylinder.

[0011] Furthermore, both sides of the sliding frame are provided with sliders, and the bracket is provided with linear rails that cooperate with the sliders.

[0012] Furthermore, the bottom of the bracket is equipped with several horizontally adjustable casters.

[0013] The beneficial effects of this invention are as follows: By leveraging the synergistic effect of the inlet and outlet limit components, the tension adjustment range is effectively shortened, constructing a closed-loop control circuit for tension sensing while avoiding interference from tension fluctuations in the adjustment range to upstream and downstream processes. Furthermore, through the linkage control of the tension sensor and the tension adjustment component, real-time acquisition and adjustment of cable tension are achieved, ensuring the dynamic stability and control accuracy of cable tension, and realizing rapid response and fine-tuning compensation.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] In this embodiment, refer to Figure 1 - Figure 4 The cable tension adjustment device, specifically implemented therein, includes a bracket 1, a tension adjustment component 2 mounted on the bracket 1, and several guide wheels 3. Tension sensors 4, which cooperate with the tension adjustment component 2, are installed between the guide wheels 3. An inlet limit component 5 and an outlet limit component 6, which cooperate with the tension adjustment component 2 and the guide wheels 3, are respectively installed at both ends of the bracket 1. The guide wheels are rotatably mounted on the bracket 1 via rolling bearings, thereby ensuring smooth and unobstructed operation of the cable during transmission while reducing frictional loss.

[0017] In use, the cable led out from the previous process is passed through the inlet limit assembly 5, the tension adjustment assembly 2, several guide wheels and the outlet limit assembly 6 in sequence, and then the cable is led out to the next process to achieve continuous and stable transmission of the cable.

[0018] By cooperating with the inlet limit component 5 and the outlet limit component 6, a stable tension adjustment zone is established between them, enabling precise control of the cable tension passing through this zone. Furthermore, the inlet limit component 5 and the outlet limit component 6 also serve as tension isolation devices, preventing tension changes within this adjustment zone from being transmitted to upstream and downstream processes, thus ensuring the stability of production in both processes.

[0019] Meanwhile, the cable entry and exit limit components 5 and 6 can control the cable's entry and exit positions and path, preventing cable deviation or jumping and ensuring its smooth entry into the tension adjustment area. The tension sensor 4 between the guide wheels 3 monitors cable tension changes in real time and feeds the signal back to the tension adjustment component 2 for automatic adjustment, ensuring the cable tension remains within the set range. This ensures cable tension stability during transmission and effectively prevents breakage or loosening caused by tension fluctuations.

[0020] Both the inlet limiting assembly 5 and the outlet limiting assembly 6 consist of several detachable horizontal guide rollers 51 and vertical guide rollers 52, which are perpendicular to each other. In this embodiment, two horizontal guide rollers 51 and two vertical guide rollers 52 are provided. In use, the cable is passed sequentially through the limiting channel formed by the two horizontal guide rollers 51 and the two vertical guide rollers 52, thereby achieving dual limiting of the cable in both the horizontal and vertical directions, effectively preventing lateral deviation or vertical jump. This ensures that the cable maintains a constant routing posture when entering the tension adjustment area, forming a stable tension adjustment area and providing accurate detection conditions for the tension sensor 4.

[0021] In this embodiment, both the transverse guide roller 51 and the vertical guide roller 52 are made of wear-resistant metal material and their surfaces are polished to reduce the frictional resistance between the cable and the guide rollers and avoid damaging the outer layer of the cable. Both ends of the bracket 1 are provided with fixing frames 11. The fixing frames 11 and the bracket 1 are respectively provided with sliding grooves 12 that cooperate with the transverse guide roller 51 and the vertical guide roller 52. One end of both the transverse guide roller 51 and the vertical guide roller 52 is provided with a sliding rod 53 and a locking block 54 that cooperate with the sliding groove 12.

[0022] The slide bar 53 and the locking block 54 are fixedly engaged via a threaded connection. In use, the ends of the horizontal guide roller 51 and the vertical guide roller 52 with the slide bar 53 are inserted into the sliding groove 12. The distance between the two guide rollers is adjusted according to the cable specifications. Then, the locking block 54 is rotated to fix the horizontal guide roller 51 and the vertical guide roller 52 to their designated positions within the sliding groove 12, thus achieving precise cable positioning. This adapts to the transmission needs of cables with different diameters, improving the equipment's versatility.

[0023] An adjustment knob is provided on the outer side of the locking block 54. By adjusting the knob, the locking block 54 can be easily rotated to quickly lock and release the guide roller, thus facilitating the operator to quickly adjust the position of the guide roller when changing cables or debugging equipment. Both the horizontal guide roller 51 and the vertical guide roller 52 are provided with limit slots that cooperate with the knob. During use, the limit slots can be locked with tools such as wrenches to help fix the guide roller and prevent it from rotating during the locking process, thereby ensuring the stability and reliability of the locking or releasing operation.

[0024] The tension adjustment assembly 2 includes a fixed pulley 21, a movable pulley 22, and a sliding frame 23. The sliding frame 23 slides reciprocally on the support 1 via a drive component 24. The fixed pulley 21 and the movable pulley 22 are rotatably mounted on the support 1 and the sliding frame 23 respectively via bearing seats. Rolling bearings are installed in the bearing seats to ensure smooth rotation of the fixed pulley 21 and the movable pulley 22, reducing resistance when the cable passes through. The fixed pulley 21 and the movable pulley 22 each have several grooves 25 arranged linearly along the axial direction. The arrangement of these grooves 25 allows the cable to form multiple annular winding paths between the fixed pulley 21 and the movable pulley 22, effectively increasing the wrap angle between the cable and the pulleys, and improving the accuracy and response speed of tension adjustment.

[0025] When the tension sensor 4 detects a change in cable tension, it controls the drive component 24 to move the sliding frame 23, thereby adjusting the relative position between the movable pulley 22 and the fixed pulley 21, changing the winding path length of the cable, and thus achieving dynamic compensation for the cable tension, ensuring that it maintains a constant force state during transmission.

[0026] In this embodiment, the driving component 24 is a cylinder. The sliding frame 23 and the bracket 1 are respectively provided with a connecting component 231 that cooperates with the cylinder and a pressure regulating valve 13. The cylinder is fixedly installed in the mounting seat on the bracket 1, and the cylinder piston rod is connected to the sliding frame 23 through the connecting component 231, thereby driving the sliding frame 23 to reciprocate and achieve precise control of the position of the movable pulley 22. The air inlet and outlet ports at both ends of the cylinder are connected to an external air source through the pressure regulating valve 13. During use, the air pressure at both ends is adjusted according to the real-time data fed back by the tension sensor 4, thereby controlling the extension or retraction stroke of the piston rod, and thus precisely controlling the moving distance of the sliding frame 23, achieving precise automatic adjustment of the cable tension.

[0027] Because the cylinder's movement trajectory is linear, the wrap angle between the fixed pulley 21, the movable pulley 22, and the cable remains constant, effectively avoiding tension disturbances caused by changes in geometric relationships. This allows the cable tensioning device to be suitable for high-precision transmission scenarios with extremely thin cables. At the same time, the constant wrap angle design significantly reduces the risk of vibration and deviation of the cable during high-speed operation, further improving system stability.

[0028] Both sides of the sliding frame 23 are provided with sliders 232, and the bracket 1 is provided with a linear guide 14 that cooperates with the sliders 232. Through the cooperation between the sliders 232 and the linear guide 14, the sliding frame 23 can slide smoothly back and forth along the guide path, thereby ensuring that the sliding frame 23 does not deviate or jam during the movement, and improving the overall transmission stability.

[0029] The bottom of the support frame 1 is equipped with several leveling casters 15. Each leveling caster 15 consists of base feet and swivel wheels. The base feet are height-adjustable for precise adjustment of the overall level of the equipment, adapting to the need for stable operation in different ground environments. The swivel wheels facilitate flexible movement and positioning of the equipment within the workshop, improving operational convenience. In use, the equipment is first moved to the target position using the swivel wheels. Then, the base feet are adjusted to contact the ground and bear weight, suspending the swivel wheels and thus stably supporting the equipment on the ground. This prevents swaying or displacement of the equipment during operation due to uneven ground conditions, ensuring the stable operation of the tension adjustment device.

[0030] The beneficial effects of this invention are as follows: Through the synergistic effect of the inlet limit component 5 and the outlet limit component 6, the tension adjustment area is effectively shortened, and a closed-loop control circuit for tension sensing is constructed, while avoiding interference from tension fluctuations in the adjustment area to the preceding and following processes. Furthermore, through the linkage control of the tension sensor 4 and the tension adjustment component 2, the real-time adjustment of the cable tension is collected, ensuring the dynamic stability and control accuracy of the cable tension, and achieving rapid response and fine-tuning compensation.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
