Description

Technical Field

[0001] This utility model relates to the field of optical cable processing technology, specifically to a circulating optical cable surface grease coating device. Background Technology

[0002] The water permeability of optical cables is an important indicator of their performance requirements. Currently, optical cable manufacturing generally uses grease filling to block water. Typically, the unwinding end continuously releases the optical cable, while the winding end continuously winds it, and the cable passes through a grease applicator. Grease is added to the grease applicator, and the cable adheres to it as it passes through, thus achieving grease coating.

[0003] For example, Chinese patent CN211826637U, entitled "Optical Cable Grout Coating Device," includes an outer shell with an inner cavity containing an oil delivery channel for grease flow. One end of the outer shell has a grease connector, and the other end has a movable bolt hole for mounting a movable bolt. Several grease through-holes are formed on one side of the outer shell. The movable bolt is positioned within the oil delivery channel through these holes. By adjusting the length of the movable bolt, the number of grease through-holes can be controlled, thereby controlling the amount of grease coated on the metal strip surface. Through this method, the optical cable grease coating device of this invention can directly adjust the oil output according to the cable core size, controlling the amount of grease sprayed onto the metal strip surface. It eliminates the need to completely fill the cable core surface with grease, preventing grease overflow, saving a significant amount of grease, reducing environmental pollution, and avoiding material waste due to excessive grease application while ensuring the optical cable's water permeability requirements.

[0004] While the optical cable grease coating device in the aforementioned patent is practical and convenient, it also has shortcomings. When the optical cable passes through the grease coating device, grease can adhere to it, thereby achieving grease coating on the optical cable. The defect of the grease coating device in the prior art is that, due to the different diameters of the optical cables, the thickness of the grease that adheres to them is different, and the grease is prone to leakage at the central outlet hole of the grease coating device as the optical cable moves. Utility Model Content

[0005] The purpose of this invention is to provide a circulating optical cable surface grease coating device to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The circulating optical cable surface grease coating device includes an oil supply pipe, a connecting pipe fixedly connected to the outlet end of the oil supply pipe, a connector detachably connected to one end of the outlet of the connecting pipe, a through hole opened in the connector, a knob gear rotatably connected in the connector, and an adjustment component provided in the connector. When the knob gear is rotated, the size of the outlet of the connecting pipe can be adjusted through the adjustment component.

[0007] Furthermore, the adjustment assembly includes a gear body that meshes with the knob gear, a fixed plate is fixedly disposed inside the connector, a plurality of adjustment blocks are slidably connected on the fixed plate, and a transmission assembly is provided between the gear body and the fixed plate. When the gear body rotates, the transmission assembly drives each of the adjustment blocks to jointly form a radial synchronous extension and retraction motion relative to the fixed plate.

[0008] Furthermore, the transmission component includes multiple sliding holes, each of which is arranged in a circumferential array on the gear body. The fixed plate is provided with multiple sliding grooves arranged in a circumferential array, and each of the sliding grooves is connected end to end in sequence. Each adjusting block is provided with a slider and a connecting post on both sides. Each slider is slidably connected in each sliding groove, and each connecting post is slidably connected in each sliding hole.

[0009] Furthermore, an oil immersion tank is provided inside the connecting pipe, and a guide roller is provided inside the oil immersion tank.

[0010] Furthermore, the connector is fixedly provided with multiple locking blocks at one end near the connecting pipe, and multiple locking slots are opened at one end of the connecting pipe outlet, with each locking block and each locking slot corresponding to each other for locking engagement.

[0011] Compared with the prior art, the beneficial effects provided by this utility model are as follows: This circulating optical cable surface grease coating device installs the connector at the outlet end of the connecting tube. According to the diameter of the optical cable, the size of the outlet of the connecting tube can be adjusted by rotating the knob gear and adjusting the component. This can avoid grease leakage, pollution and waste, and can control the thickness of the grease left on the optical cable. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-6 The present invention provides a technical solution: the circulating optical cable surface grease coating device includes an oil supply pipe 1, a connecting pipe 2 fixedly connected to the outlet end of the oil supply pipe 1, a connector 3 detachably connected to one end of the outlet of the connecting pipe 2, a through hole 9 opened in the connector 3, a knob gear 4 rotatably connected in the connector 3, and an adjustment component provided in the connector 3. When the knob gear 4 is rotated, the size of the outlet of the connecting pipe 2 can be adjusted by the adjustment component.

[0022] In this embodiment, the adjustment assembly includes a gear body 15 that meshes with the knob gear 4. A fixed plate 10 is fixedly disposed inside the connector 3. Multiple adjustment blocks 13 are slidably connected on the fixed plate 10. A transmission assembly is provided between the gear body 15 and the fixed plate 10. When the gear body 15 rotates, the transmission assembly drives the adjustment blocks 13 to jointly form a radial synchronous extension and retraction motion relative to the fixed plate 10. The transmission assembly includes multiple sliding holes 16, which are arranged in a circumferential array on the gear body 15. Multiple sliding grooves 11 are arranged in a circumferential array on the fixed plate 10, and the sliding grooves 11 are connected end to end in sequence. Each adjustment block 13 has a slider 12 and a connecting post 14 on both sides. Each slider 12 is divided into... Each connecting post 14 is slidably connected within a sliding groove 11 and a sliding hole 16. Specifically, when the knob gear 4 is rotated, the gear body 15 is driven to rotate through meshing transmission, which pushes the connecting post 14 to move through the inner wall of the sliding hole 16. Since the sliding groove 11 has restricted the movement path of the slider 12 on the side of the adjusting block 13 close to the fixed plate 10, each slider 12 moves linearly along the path of the corresponding sliding groove 11. The synchronous linear movement of multiple adjusting blocks 13 is combined into a radial synchronous telescopic movement relative to the fixed plate 10, thereby adjusting the size of the through hole 9 in the connector 3. In addition, multiple adjusting blocks 13 are responsible for scraping off excess grease from the surface of the optical cable, precisely controlling the thickness and quality of the final coating layer.

[0023] In this embodiment, an oil immersion tank 5 is provided inside the connecting pipe 2, and a guide roller 7 is provided inside the oil immersion tank 5. Specifically, a wire-passing hole 6 for the optical cable to pass through is provided inside the connecting pipe 2, and the outer diameter of the oil immersion tank 5 is larger than that of the wire-passing hole 6, so that when the optical cable passes under the guide roller 7, the optical cable is completely immersed in the grease in the oil immersion tank 5, and the grease is evenly attached to the surface of the optical cable body. This is particularly beneficial for filling the gaps between the cable cores and is very effective for optical cables with high requirements for waterproofing and moisture resistance.

[0024] In this embodiment, a plurality of locking blocks 8 are fixedly provided at one end of the connector 3 near the connecting pipe 2, and a plurality of locking slots are provided at one end of the outlet of the connecting pipe 2. Each locking block 8 and each locking slot are engaged in a corresponding manner. Specifically, this facilitates the installation and disassembly of the connector 3, and the inspection and cleaning of its interior, preventing grease from adhering to the interior of the connector 3.

[0025] In another embodiment, both the inlet and outlet of the connecting tube 2 are provided with connectors 3. The diameter of the through hole 9 inside the connector 3 at the inlet end is adjusted according to the diameter of the optical cable, so that each adjusting block 13 maintains a very small gap (or even slight contact) with the surface of the optical cable. This greatly limits the leakage of grease from the inlet and avoids waste. At the same time, it guides the optical cable through the center, laying the foundation for subsequent coating. The multiple adjusting blocks 13 in the connector 3 at the outlet end are responsible for scraping off excess grease from the surface of the optical cable, accurately controlling the thickness and quality of the final coating layer. The dual-point positioning (inlet and outlet) greatly improves the stability of the optical cable passing through the system and ensures that the optical cable axis coincides with the center of the connecting tube 2. This directly brings the benefit of a more uniform coating layer and avoids one-sided scraping or uneven thickness caused by optical cable eccentricity.

[0026] Working principle: This circulating optical cable surface grease coating device installs the connector 3 at the outlet end of the connecting tube 2. Depending on the diameter of the optical cable, when the knob gear 4 is rotated, the gear body 15 is driven to rotate through meshing transmission. This drives the connecting column 14 to move through the inner wall of the sliding hole 16. Since the sliding groove 11 has restricted the movement path of the slider 12 on the side of the adjusting block 13 close to the fixed plate 10, each slider 12 moves linearly along the path of the corresponding sliding groove 11. The synchronous linear movement of multiple adjusting blocks 13 is combined into a radial synchronous telescopic movement relative to the fixed plate 10, thereby adjusting the size of the through hole 9 inside the connector 3. In addition, multiple adjusting blocks 13 are responsible for scraping off excess grease from the surface of the optical cable, accurately controlling the thickness and quality of the final coating layer, and avoiding grease leakage, pollution and waste.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
