Description

Technical Field

[0001] This application belongs to the technical field of wrapping equipment, and more specifically, it relates to a water-blocking tape tensioning and fixing component and a wrapping mechanism. Background Technology

[0002] With the continuous improvement of automation in the power industry, automated wrapping machines and other equipment have been widely used in power systems. Among these, the installation and fixing mechanism of water-blocking tape is crucial to the quality of water-blocking tape winding. Furthermore, a stable and easy-to-operate water-blocking tape fixing mechanism can not only save winding time and improve the quality of submarine cable insulation cores, but also reduce reliance on operator skill levels. Currently, the main problems with existing water-blocking tape fixing mechanisms on the market are as follows:

[0003] (1) Poor operability and difficulty in ensuring winding quality: As the wrapping machine winds, the water-blocking tape often becomes loose and the damping force is unstable, affecting the wrapping quality of the submarine cable insulation core surface;

[0004] (2) Poor applicability and high requirements for operators' operating skills: At present, the water-blocking tape fixing mechanism can only be used with one type of water-blocking tape. It will not be applicable to other types. It is not easy to control the damping force required for winding. The damping force is easy to change with different rotation positions. The operator's visual and experience judgment may result in uneven winding or unstable quality of submarine cable insulation core due to differences in operation between different people.

[0005] (3) Low efficiency and high labor intensity: During the production process, operators need to continuously observe and intervene; when replacing the water-blocking belt, the damping force must be readjusted. There is a lot of repetitive work, resulting in low efficiency, high labor intensity, and easy fatigue and errors. Summary of the Invention

[0006] To address the problems mentioned in the background art, this utility model provides a water-blocking tape tensioning and fixing component and a wrapping mechanism, which can not only firmly fix the water-blocking tape, but also stably provide the damping force required for wrapping, so that the water-blocking tape is tightly wrapped around the surface of the submarine cable insulation core. At the same time, it can also flexibly adjust different damping forces according to different models of water-blocking tape, effectively improving production efficiency and the quality of submarine cable insulation core.

[0007] To address this, the present invention provides a water-blocking belt tensioning and fixing assembly, which includes an arc-shaped fixing plate, a central shaft fixedly connected to the center of the arc-shaped fixing plate, a wedge-shaped fixing shaft sleeved on the central shaft, a friction sleeve between the wedge-shaped fixing shaft and the central shaft, a wedge-shaped locking shaft threadedly connected to the wedge-shaped fixing shaft, a tensioning ring between the wedge-shaped fixing shaft and the wedge-shaped locking shaft, a top block between the central shaft and the wedge-shaped locking shaft, an adjusting wheel threadedly connected to the front end of the central shaft, and a pressure spring sleeved on the central shaft between the adjusting wheel and the top block.

[0008] Preferably, the tensioning ring is composed of four wedges, each wedge having a spring groove on both sides, and a spring ring inside the spring groove, with two spring rings connecting the four wedges.

[0009] Preferably, the two ends of the tensioning ring are aligned with the taper of the wedge-shaped fixing shaft and the wedge-shaped locking shaft, respectively.

[0010] Preferably, a fixing ring is sleeved at the end of the wedge-shaped fixing shaft, and a limiting plate is provided in front of the fixing ring, the limiting plate being connected to the arc-shaped fixing plate.

[0011] Preferably, the top block has a limiting groove on its inner side, and the central shaft has a positioning pin, with both ends of the positioning pin located in the limiting groove.

[0012] Preferably, two friction sleeves are provided.

[0013] Meanwhile, this utility model provides a wrapping mechanism, including the above-mentioned water-blocking tape tensioning and fixing assembly, and also includes a main board, a power drive assembly and a toothed ring. The main board has a central hole, and a toothed ring groove is provided around the central hole on the main board. The toothed ring groove is slidably connected to the toothed ring, and an arc-shaped fixing plate is fixed on the toothed ring.

[0014] Preferably, the power drive assembly includes a drive motor, a drive gear, and a driven gear. The drive motor is fixed on the motherboard, and the output end of the drive motor passes through the motherboard and connects to the drive gear. A driven gear that meshes with the drive gear is provided above the drive gear, and the driven gear meshes with a gear ring.

[0015] Preferably, the driving gear and the driven gear are provided with gear covers.

[0016] The beneficial effects of this utility model are:

[0017] (1) This utility model provides a water-blocking tape tensioning and fixing assembly. Through the cooperation of the wedge-shaped fixing shaft, the wedge-shaped locking shaft and the tensioning ring, the wedge-shaped locking shaft is rotated, so that the wedge-shaped locking shaft moves axially. As the wedge-shaped locking shaft gradually penetrates between the tensioning ring and the wedge-shaped fixing shaft, the outer diameter of the tensioning ring is changed, thereby achieving the effect of water-blocking tape tensioning. When replacing the water-blocking tape, only the wedge-shaped locking shaft needs to be rotated to fix the new water-blocking tape. There is no need to readjust the damping force, which ensures the consistency of the damping force before and after replacing the water-blocking tape, ensures the quality of the water-blocking tape winding on the surface of the submarine cable insulation core, reduces the workload and improves the work efficiency.

[0018] (2) This utility model provides a water-blocking tape tensioning and fixing assembly. Through the cooperation of an adjusting wheel, a pressure spring, a top block, a friction sleeve, and a wedge-shaped fixing shaft, the adjusting wheel moves axially, compressing the pressure spring, so that the top block and the wedge-shaped fixing shaft press against the friction sleeve. The friction sleeve has a large coefficient of friction and strong wear resistance, which can provide stable and sufficient damping force for the water-blocking tape, and can provide the stable damping force required during winding. This utility model can also be applied to different models of water-blocking tape (such as 80mm, 100mm, etc.), and the damping force can be flexibly adjusted according to the tensile strength of different models and the tightness requirements of the wrapping of the submarine cable insulation core, so as to ensure the winding quality.

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application. Example

[0028] A water-blocking tape tensioning and fixing component, such as Figure 1-2 As shown, it is equipped with an arc-shaped fixing plate 1, with a central shaft 2 fixedly connected to the center of the arc-shaped fixing plate 1. A wedge-shaped fixing shaft 3 is sleeved on the central shaft 2, and a friction sleeve 4 is provided between the wedge-shaped fixing shaft 3 and the central shaft 2. The wedge-shaped fixing shaft 3 is threadedly connected to a wedge-shaped locking shaft 5, and a tensioning ring 8 is provided between the wedge-shaped fixing shaft 3 and the wedge-shaped locking shaft 5. By rotating the wedge-shaped locking shaft 5, the wedge-shaped locking shaft 5 moves axially and gradually penetrates between the tensioning ring 8 and the wedge-shaped fixing shaft 3, thereby changing the outer diameter of the tensioning ring 8 and achieving the effect of tensioning the water-blocking tape 22. When the water-blocking tape 22 needs to be replaced, only the wedge-shaped locking shaft 5 needs to be rotated to fix the new water-blocking tape 22 without readjusting the damping force. This ensures the consistency of the damping force before and after replacing the water-blocking tape 22, ensures the winding quality of the water-blocking tape 22 on the surface of the submarine cable insulation core 23, reduces the workload, and improves the work efficiency.

[0029] A top block 6 is provided between the central shaft 2 and the wedge-shaped locking shaft 5. The front end of the central shaft 2 is threadedly connected to an adjusting wheel 7. A pressure spring 9 is sleeved on the central shaft 2 between the adjusting wheel 7 and the top block 6. Rotating the adjusting wheel 7 causes it to move axially, thereby compressing the pressure spring 9, causing the top block 6 and the wedge-shaped fixing shaft 3 to press against the friction sleeve 4. The friction sleeve 4 has a large coefficient of friction and strong wear resistance, which can provide stable and sufficient damping force for the water-blocking tape 22. At the same time, through the above structure, the water-blocking tape tensioning and fixing assembly can be applied to different models of water-blocking tape 22 (such as 80mm, 100mm, etc.), and the damping force can be flexibly adjusted according to the tensile strength of different models and the tightness requirements of wrapping the submarine cable insulation core 23, so as to ensure the winding quality.

[0030] Among them, such as Figure 3 As shown, the tensioning ring 8 is composed of four wedge-shaped bodies. Each of the four wedge-shaped bodies has a spring ring groove 10 on both sides, and a spring ring 11 is provided in the spring ring groove 10. The four wedge-shaped bodies are connected by two spring rings 11.

[0031] Furthermore, the taper of the end connecting the tensioning ring 8 to the wedge-shaped fixed shaft 3 is consistent with the taper of the wedge-shaped fixed shaft 3, and the taper of the end connecting the tensioning ring 8 to the wedge-shaped locking shaft 5 is consistent with the taper of the wedge-shaped locking shaft 5, thereby ensuring that both ends of the tensioning ring 8 can maintain a tight fit with the wedge-shaped fixed shaft 3 and the wedge-shaped locking shaft 5.

[0032] like Figure 1As shown, a fixing ring 12 is sleeved at the end of the wedge-shaped fixing shaft 3, and a limiting plate 13 is provided in front of the fixing ring 12. The limiting plate 13 is fixed to the arc-shaped fixing plate 1 by bolts, which is used to limit the water-blocking strip 22 axially.

[0033] Furthermore, such as Figure 2 As shown, the top block 6 has a limiting groove on its inner side, and a positioning pin 14 is provided on the central shaft 2. The two ends of the positioning pin 14 are located in the limiting groove, and the positioning pin 14 and the limiting groove cooperate to prevent the top block 6 from rotating.

[0034] Furthermore, there are two friction sleeves 4, one located behind the top block 6 and the other located in front of the fixing ring 12. Example

[0035] Based on Embodiment 1, this utility model provides a wrapping mechanism, such as... Figure 4 As shown, the wrapping mechanism includes a main board 15, a power drive assembly, a toothed ring 17, and a water-blocking tape tensioning and fixing assembly. The main board 15 has a central hole 16 for the submarine cable insulation core 23 to pass through. A toothed ring groove is provided around the central hole 16 on the main board 15. The toothed ring groove is slidably connected to the toothed ring 17. The water-blocking tape tensioning and fixing assembly is fixed on the toothed ring 17.

[0036] like Figure 5 As shown, a power drive assembly is also fixedly connected to the main board 15. The power drive assembly includes a drive motor 18, a drive gear 19, and a driven gear 20. The drive motor 18 is fixed to the main board 15. The output end of the drive motor 18 passes through the main board 15 and is connected to the drive gear 19. A driven gear 20 that meshes with the drive gear 19 is provided above the drive gear 19. The driven gear 20 meshes with the gear ring 17.

[0037] Specifically, the drive motor 18 drives the drive gear 19 to rotate, the drive gear 19 drives the driven gear 20 to rotate, the driven gear 20 drives the gear ring 17 to rotate, and the gear ring 17 rotates around the submarine cable insulation core 23, wrapping the water-blocking tape 22 around the surface of the submarine cable insulation core 23.

[0038] Furthermore, such as Figure 4 As shown, the driving gear 19 and the driven gear 20 are provided with gear covers 21 to prevent dust from entering between the driving gear 19 and the driven gear 20, prevent the gears from jamming, extend the service life of the gears, and play a protective role.

[0039] The working principle of this utility model is as follows:

[0040] During operation, the submarine cable insulation core 23 is fixed by the guide mechanism of the automatic wrapping machine. The guide mechanism of the automatic wrapping machine is used to stably pass the submarine cable insulation core 23 through the center hole 16 of the main board 15. This is existing technology and will not be described in detail here. The water-blocking tape 22 is installed on the water-blocking tape tensioning and fixing assembly. First, the wedge-shaped locking shaft 5 is rotated to tension the water-blocking tape 22 by changing the outer diameter of the tensioning ring 8. The adjusting wheel 7 is rotated to move axially, thereby compressing the pressure spring 9, so that the top block 6 and the wedge-shaped fixing shaft 3 are pressed against the friction sleeve 4, providing stability and sufficient damping force for the water-blocking tape 22. Then, one end of the water-blocking tape 22 is bonded to the submarine cable insulation core 23. The drive motor 18 drives the drive gear 19 to rotate. The drive gear 19, driven gear 20 and gear ring 17 mesh and rotate in sequence. The gear ring 17 rotates around the submarine cable insulation core 23. As the submarine cable insulation core 23 passes through the center hole 16, the water-blocking tape 22 is wrapped around the surface of the submarine cable insulation core 23.

[0041] It is worth noting that the wrapping mechanism mentioned in this utility model is installed on an automated wrapping machine and works in conjunction with the automated wrapping machine to complete the wrapping work.

[0042] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
