Description

Technical Field

[0001] This application relates to the field of cable manufacturing, and in particular to a buffer guide device for cable manufacturing. Background Technology

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a cable that is like a rope, made up of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being energized internally and insulated externally. There are power cables, control cables, compensating cables, shielded cables, etc.

[0003] Currently, in cable production, guiding devices are needed to ensure the stability of cable transport. Generally, the tension of the cable is adjusted manually using guiding devices. However, during cable transport, the length of the transported section may change. In such cases, it is very difficult to adjust the tension manually, which is not conducive to improving the cable transport efficiency. Utility Model Content

[0004] To address the issue that cable length changes during transport and the difficulty of manually adjusting tension, this application provides a buffer guide device for cable production.

[0005] The buffer guiding device for cable production provided in this application adopts the following technical solution:

[0006] The device includes a base and a movable base. A vertical plate is mounted on the movable base, and a vertical plate is mounted on the vertical plate. A guide rail is mounted on the vertical plate, and a lifting block is slidably mounted on the guide rail. A first connecting shaft is mounted on the lifting block, and a tensioning wheel is connected to the first connecting shaft via a bearing. An extension block is mounted on the side of the vertical plate, and an auxiliary gas spring is mounted on the extension block. One end of the auxiliary gas spring is connected to the lifting block.

[0007] By adopting the above technical solution, when the tensioning wheel is subjected to an upward pulling force, it drives the lifting block to move upward along the guide rail, compressing the auxiliary gas spring. The gas spring generates a counterforce, balancing the cable tension and maintaining tension stability.

[0008] Preferably, two limiting rods are installed on both sides of the guide rail on the vertical plate, and the limiting rods pass through the inner side of the lifting block and are slidably connected to the lifting block.

[0009] By adopting the above technical solution, two limit rods are symmetrically arranged on both sides of the guide rail, which effectively prevents the lifting block from deflecting during the movement.

[0010] Preferably, a horizontal rod is installed at the middle of the vertical plate, and two second connecting shafts are adjustablely installed at both ends of the horizontal rod, with side guide wheels installed on the second connecting shafts.

[0011] By adopting the above technical solution, the cable passes between the two side guide wheels and then around the tensioning wheel, which facilitates transportation.

[0012] Preferably, a rotating rod is rotatably mounted inside the transverse rod, and a set of opposing threads are provided at both ends of the rotating rod. The rotating rod is connected to two moving blocks through opposing threads, and the second connecting shaft is mounted on the moving blocks.

[0013] By adopting the above technical solution, the drive motor drives the rotating rod to rotate. Since the threads at both ends of the rotating rod rotate in opposite directions, the two moving blocks move synchronously towards or away from each other.

[0014] Preferably, a moving groove is provided on the transverse rod above the moving block, and a guide wheel is installed on the upper part of the moving block. The guide wheel is located inside the moving groove and can move inside the moving groove.

[0015] By adopting the above technical solution, the two moving blocks move synchronously towards or away from each other, and the guide wheels roll in the moving groove, ensuring that the moving blocks move smoothly without shaking.

[0016] Preferably, one end of the rotating rod is connected to a drive motor, the output end of the drive motor and the rotating rod are connected by a coupling, and the drive motor is connected to the horizontal rod.

[0017] By adopting the above technical solution, the output end of the drive motor and the rotating rod are connected by a coupling. The drive motor is connected to the transverse rod. When it is necessary to change the guide width, the drive motor is started to provide power.

[0018] Preferably, slide rails are installed on both sides of the base, and two sliders are installed on both sides of the lower part of the movable seat. The movable seat is slidably connected to the slide rails via the sliders. A push plate is installed on the lower part of one side of the movable seat, and a push cylinder is installed on the base. The output end of the push cylinder is connected to the push plate.

[0019] By adopting the above technical solution, the slider is embedded with a linear bearing to ensure smooth movement, and the push cylinder is a hydraulic cylinder or a pneumatic cylinder, which drives the moving seat to move laterally through the push plate.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application achieves automatic adjustment of the tensioning wheel according to the change of cable tension by using the lifting block, guide rail and auxiliary gas spring, so as to maintain constant cable tension and avoid excessive tightness or looseness. At the same time, it can effectively absorb the impact caused by sudden changes in cable tension, prevent damage to the cable surface and improve product quality.

[0022] 2. This application adopts an adjustable-spacing side guide wheel design, and achieves synchronous and symmetrical movement of the two side guide wheels through a drive motor and a reverse thread structure. This can adapt to the production needs of cables with different diameters. The design of the limit rod and the moving groove in conjunction with the guide wheels ensures that the lifting block and the moving block remain stable during movement, reducing shaking and improving guiding accuracy.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a buffer guide device for cable production. Please refer to... Figures 1 to 4The system includes a base 1 and a movable base 2. A vertical plate 3 is mounted on the movable base 2, and a vertical plate 4 is mounted on the vertical plate 3. A guide rail 5 is mounted on the vertical plate 4, and a lifting block 6 is slidably mounted on the guide rail 5. The lifting block 6 has a slider inside that matches the guide rail 5, forming a precision sliding assist. Two limit rods 7 are symmetrically arranged on both sides of the guide rail 5 to effectively prevent the lifting block 6 from deflecting during movement. A first connecting shaft 8 is mounted on the lifting block 6, and a tensioning wheel 9 is connected to the first connecting shaft 8 via a bearing. An extension block 20 is mounted on the side of the vertical plate 4, and an auxiliary gas spring 21 is mounted on the extension block 20. One end of the auxiliary gas spring 21 is connected to the lifting block 6. Two limit rods 7 are mounted on both sides of the guide rail 5 on the vertical plate 4. The limit rods 7 pass through the inside of the lifting block 6 and are slidably connected to the lifting block 6. When the cable tension increases, the tensioning wheel 9 receives an upward pulling force, driving the lifting block 6 to move upward along the guide rail 5, compressing the auxiliary gas spring 21. The gas spring generates a counterforce to balance the cable tension and maintain tension stability. When the cable tension decreases, the lifting block 6 moves downward under the thrust of the gas spring, always maintaining the cable at a proper tension. The limit rod 7 ensures that the lifting block 6 moves in a straight line, preventing jamming.

[0030] Please refer to Figure 3 and Figure 4 A horizontal rod 10 is horizontally installed at the middle of the vertical plate 4. Two second connecting shafts 11 are adjustablely installed at both ends of the horizontal rod 10. Side guide wheels 12 are installed on the second connecting shafts 11. A rotating rod 13 is rotatably installed inside the horizontal rod 10. A set of opposing threads 14 are opened at both ends of the rotating rod 13. The rotating rod 13 is connected to two moving blocks 15 through the opposing threads 14. The second connecting shafts 11 are installed on the moving blocks 15. A moving groove 17 is opened on the horizontal rod 10 above the moving blocks 15. A guide wheel 18 is installed on the upper part of the moving blocks 15. The guide wheel 18 is located inside the moving groove 17 and can move... The internal movement of the moving groove 17 is achieved by connecting one end of the rotating rod 13 to a drive motor 19. The output end of the drive motor 19 and the rotating rod 13 are connected by a coupling. The drive motor 19 is connected to the transverse rod 10. When it is necessary to change the guide width, the drive motor 19 is started, which drives the rotating rod 13 to rotate. Since the threads at both ends of the rotating rod 13 rotate in opposite directions, the two moving blocks 15 move synchronously towards or away from each other. The guide wheel 18 rolls in the moving groove 17 to ensure that the moving block 15 moves smoothly without shaking. By controlling the rotation angle of the drive motor 19, the distance between the two side guide wheels 12 can be precisely controlled to adapt to cables of different diameters.

[0031] Please refer to Figure 1 and Figure 4The base 1 has slide rails 22 installed on both sides, and two sliders 23 are installed on the lower sides of the movable seat 2. The movable seat 2 is slidably connected to the slide rails 22 via the sliders 23. A push plate 16 is installed on the lower side of one side of the movable seat 2. A push cylinder 24 is installed on the base 1. The output end of the push cylinder 24 is connected to the push plate 16. The movable seat 2 forms a precision sliding fit with the slide rails 22 on the base 1 via the sliders 23. The sliders 23 are embedded with linear bearings to ensure smooth movement. The push cylinder 24 is a hydraulic cylinder or a pneumatic cylinder. It drives the movable seat 2 to move laterally via the push plate 16. The movement range can be set according to actual needs.

[0032] The implementation principle of a buffer guide device for cable production according to an embodiment of this application is as follows: The cable passes between two side guide wheels 12 and then around a tension wheel 9. When the cable tension changes, the tension wheel 9 moves along the guide rail 5 via a lifting block 6, and an auxiliary gas spring 21 provides a buffering effect to maintain stable cable tension. When it is necessary to accommodate cables of different specifications, the drive motor 19 drives the rotating rod 13 to rotate, and the two moving blocks 15 move synchronously towards or away from each other through the relative thread 14, thereby adjusting the distance between the two side guide wheels 12. The push cylinder 24 can push the moving seat 2 to move along the slide rail 22 to adjust the position of the entire guide device.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
