Description

Technical Field

[0001] This utility model relates to the field of optical cable manufacturing technology, specifically to a cable length control device. Background Technology

[0002] Cables, as important carriers of electrical energy or signals, play a vital role in modern industry, transportation, construction and other fields. During the cable laying process, ensuring the accuracy and controllability of cable length is crucial. Cable length control devices are designed to meet this need. They can help users quickly and accurately adjust and measure the cable length, thereby ensuring that the cable laying process is not difficult or wasteful of resources due to length issues.

[0003] A search revealed that Chinese patent CN113697593B discloses a cable winding device for precise control of cable reel length. The device uses the movement of a pressure rod to cause a movable connecting rod to rotate a stop block via a pull rod, separating the stop block from the locking block. As the support rod reciprocates, the locking block gradually moves upwards. When the locking block reaches its uppermost position, it clamps the optical cable, thus achieving precise control over the length of the wound optical cable.

[0004] However, in actual use, the cable may loosen due to its own weight when passing through the cable threading frame, resulting in the cable not being tightly wound on the winding roller and thus reducing the accuracy of cable length control. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cable length control device, which can effectively solve the problem that the cable wound on the winding roller is not tight, resulting in low accuracy of cable length.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a cable length control device, including a device base, a lower clamping plate and a support frame arranged above the device base, a switch communicatively connected to the support frame, a rope winding roller arranged above the lower clamping plate, a metering component arranged below the rope winding roller, a second drive motor arranged at the top of the support frame, an adjustment component arranged at the output end of the second drive motor, a first drive motor arranged below the adjustment component, a rotating mechanism arranged at the output end of the first drive motor, a sliding component drivingly connected to the rotating mechanism, and a fixing component arranged above the sliding component.

[0008] Furthermore, one end of the rope winding roller is rotatably mounted on the device base, and the other end of the rope winding roller is rotatably mounted on the lower clamping plate.

[0009] Furthermore, the adjustment assembly includes a threaded rod fixedly mounted on the output shaft of the second drive motor, and the threaded rod is threadedly connected to an upper clamping plate.

[0010] Furthermore, the threaded rod is rotatably mounted on the support frame, and the surface of the support frame is provided with a first sliding groove, on which an upper clamping plate is slidably connected.

[0011] Furthermore, the quantitative component includes a fixing block fixedly installed on the upper surface of the device base, the fixing block being rotatably connected to a second spring, the second spring being fixedly connected to a connecting rod, the end of the connecting rod near the fixing block being fixedly connected to the second spring, and a switch being provided below the connecting rod.

[0012] Furthermore, the rotating mechanism includes a first rotating wheel fixedly mounted on the output shaft of a first drive motor, the first rotating wheel being driven by a belt, the belt being driven by a second rotating wheel, the second rotating wheel being fixedly connected to a bidirectional lead screw, the bidirectional lead screw being threadedly connected to a slider, and a second sliding groove being provided on the upper surface of the device base, the second sliding groove being slidably connected to the slider.

[0013] Furthermore, the slider is fixedly connected to a water tank, the water tank is fixedly connected to multiple sets of nozzles, a push rod is provided on the top of the water tank, and a cutter is fixedly connected to the push rod.

[0014] Furthermore, the water tank is fixedly connected to a fixing component, which includes a threading frame fixedly installed on the water tank. One end of the threading frame is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to an elastic plate. The fixing component is provided in three sets, and its parts and installation methods are the same. The elastic plate is fixedly installed inside the threading frame.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] I. This utility model, by setting a quantitative component and a precisely controlled drive system, can immediately stop winding when the cable is wound on the winding roller to a preset length and touches the switch, thereby achieving precise control of the cable length and effectively solving the problem of reduced length accuracy caused by loose cable winding.

[0018] II. By setting an adjustment component and a lower clamping plate fixedly installed on the device base, this utility model can stably clamp the winding roller and prevent it from deviating in position during rotation. At the same time, the reciprocating motion of the sliding component provides stable support for the winding roller, further enhancing the stability of cable winding and ensuring that the cable maintains a fixed spacing during the winding process.

[0019] Third, this utility model cleans the cable by setting up a water tank and a spray nozzle, which effectively avoids the increase of cable winding thickness due to dirt on the cable surface, thereby reducing the length control error caused by dirt. In addition, the cutter cuts the cable by controlling the push rod, ensuring the accuracy and efficiency of the cutting process. The setting of the fixing component ensures that the cable is subjected to uniform force during the winding process of the rope roller, avoiding damage to the inside of the cable.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] A cable length control device, as shown in the attached document. Figures 1-5 The device includes a base 1, a lower clamping plate 2 and a support frame 4 on top of the base 1, and a switch 23 connected to the support frame 4. The switch 23 is height-adjustable, allowing for precise control of cable lengths of different lengths. A rope winding roller 25 is positioned above the lower clamping plate 2, with one end rotatably mounted on the base 1 and the other end rotatably mounted on the lower clamping plate 2. The adjustment assembly includes a threaded rod 7 fixedly mounted on the output shaft of a second drive motor 6. The threaded rod 7 is threadedly connected to an upper clamping plate 3 and rotatably mounted on the support frame 4. A first sliding groove 8 is formed on the surface of the support frame 4, and the upper clamping plate 3 is slidably connected to the first sliding groove 8. In the open state, the second drive motor 6 drives the threaded rod 7 to rotate via its output shaft. The threaded rod 7 drives the upper clamping plate 3 to move downward through the threaded relationship between the upper clamping plate 3 and the lower clamping plate 2 fixedly installed on the device base 1. The upper clamping plate 3, together with the lower clamping plate 2 fixedly installed on the device base 1, clamps the rope winding roller 25, providing a stable working environment for the subsequent winding of the cable by the rope winding roller 25, effectively preventing the position deviation of the rope winding roller 25 during rotation, thereby initially improving the control of the cable length. A metering component is provided below the rope winding roller 25. The metering component includes a fixing block 20 fixedly installed on the upper surface of the device base 1. The fixing block 20 is rotatably connected to a second spring 22. The second spring 22 is fixedly connected to a connecting rod 21. The end of the connecting rod 21 near the fixing block 20 is fixedly connected to the second spring 22. A switch 23 is provided below the connecting rod 21.

[0030] In the above technical solution, after the rope winding roller 25 is clamped and operates for a period of time, when the cable touches the switch 23, the switch 23 transmits a signal to the first drive motor 5. The first drive motor 5 receives the signal and stops operating, thereby achieving precise control of the cable length. The top of the support frame 4 is equipped with a second drive motor 6, and the output end of the second drive motor 6 is equipped with an adjustment component. Below the adjustment component is the first drive motor 5, and the output end of the first drive motor 5 is equipped with a rotating mechanism. The rotating mechanism includes a first rotating wheel 24 fixedly mounted on the output shaft of the first drive motor 5, and the first rotating wheel 24 is driven by a belt 1. 9. A second rotating wheel 26 is connected to a belt 19 for transmission. A bidirectional lead screw 10 is fixedly connected to the second rotating wheel 26. A slider 11 is threadedly connected to the bidirectional lead screw 10. A second sliding groove 9 is provided on the upper surface of the device base 1. The slider 11 is slidably connected to the second sliding groove 9. In the open state, the first drive motor 5 drives the first rotating wheel 24 to rotate through its output shaft. The rotation of the first rotating wheel 24 drives the belt 19 to rotate, which in turn drives the second rotating wheel 26 to rotate. This causes the bidirectional lead screw 10 to rotate within the second sliding groove 9. The rotation of the second sliding groove 9, through the threaded action, drives the slider 11 to reciprocate within the second sliding groove 9. The sliding component provides stable support when the subsequent winding roller 25 winds the cable. A water tank 18 is fixedly connected to the slider 11, and multiple spray nozzles 17 are fixedly connected to the water tank 18. A push rod 15 is installed at the top of the water tank 18, and a cutter 16 is fixedly connected to the push rod 15. The cutter 16 is fitted against the inner wall of the water tank 18 near the cable threading frame 12, thereby reducing errors when cutting the cable. The slider 11 distributes the liquid stored inside to the multiple spray nozzles 17, effectively cleaning the cable surface. During the winding process of the cable by the winding roller 25, it effectively prevents the increase of dirt on the cable surface from causing cable entanglement. The thickness of the cable causes it to prematurely touch the switch 23, resulting in lower accuracy in controlling the cable length. The rotating mechanism is connected to a sliding component, and a fixed component is provided above the sliding component. The water tank 18 is fixedly connected to the fixed component. The fixed component includes a cable guide 12 fixedly installed on the water tank 18. One end of the cable guide 14 is fixedly connected to the cable guide 12, and the other end of the first spring 14 is fixedly connected to an elastic plate 13. There are three sets of fixed components, and their parts and installation methods are the same. The elastic plate 13 is fixedly installed inside the cable guide 12. The cooperation of multiple sets of fixed components makes the cable surface evenly stressed, avoiding damage to the inside of the cable.

[0031] Working principle: In use, place both ends of the winding roller 25 on the lower clamping plate 2 and the device base 1 respectively. Then, turn on the second drive motor 6. The second drive motor 6 drives the threaded rod 7 to rotate through the output shaft, thereby causing the upper clamping plate 3 to move downward. The cooperation between the upper clamping plate 3 and the lower clamping plate 2 clamps the winding roller 25. Then, pass the cable through the water tank 18 and the cable threading frame 12. The nozzles 17 on the water tank 18 clean the cable. When the cable passes through the cable threading frame 12, the first spring 14, which is fixedly installed on the inner wall of the cable threading frame 12, will squeeze the elastic plate 13, and the elastic plate 13 will clamp the cable. This ensures that the cable is properly secured by the winding roller during the reciprocating motion of the sliding component. During the winding process, a fixed spacing is maintained. Then, the first drive motor 5 is turned on. The first drive motor 5 drives the first rotating wheel 24 to rotate through the output shaft. The first rotating wheel 24 drives the second rotating wheel 26 to rotate through the belt 19, thereby causing the bidirectional lead screw 10 to rotate. The bidirectional lead screw 10 drives the slider 11 to reciprocate on the second slide groove 9 through the thread action between it and the slider 11. When the cable wound on the winding roller 25 touches the switch 23, the switch 23 transmits a signal to the first drive motor 5, and the first drive motor 5 stops working. Then, by controlling the push rod 15, the cutter 16 cuts the cable, thereby achieving precise control of the cable length.
