Description

Technical Field

[0001] This invention belongs to the technical field of specialized equipment for manufacturing conductors or cables, and particularly relates to a stranded optical cable filling device and its working method. Background Technology

[0002] During the production process, bidirectional alternating stranded optical cables require the coating of water-blocking grease on their surface. Along the length of the cable, some sections are twisted (called "twisted sections"), while others are straight (called "straight sections"). The straight sections are located between two twisted sections. During coating, the twisted sections rotate, causing the water-blocking grease within the coating area to be pushed away from the cable. When the straight sections move into the coating area, the cable stops rotating. At this point, due to the inertia caused by the rotation of the twisted sections moving the water-blocking grease away from the cable, the grease cannot be evenly coated on the surface of the straight sections.

[0003] Therefore, when applying water-blocking grease to the straight section of a bidirectional alternating stranded optical cable, the inertia caused by the rotation of the previous twisted section resulting in the water-blocking grease moving away from the bidirectional alternating stranded optical cable causes a technical problem where the water-blocking grease cannot be uniformly coated on the surface of the straight section. It is necessary to design a stranded optical cable grease filling device and its working method.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one device for filling stranded optical cable with cable grease and its working method.

[0006] In a first aspect, embodiments of this disclosure provide a stranded optical cable grease filling device, comprising:

[0007] A filling device configured to coat the outside of the optical cable with water-blocking grease;

[0008] The filling device includes: a limiting tube;

[0009] An optical cable is inserted inside the limiting tube, and a filling cavity is formed between the outer wall of the optical cable and the inner wall of the limiting tube. The filling cavity is filled with water-resistant grease.

[0010] The inner wall of the limiting tube is provided with several movable mechanisms at equal intervals along the circumference.

[0011] When the twisted section of the optical cable passes through the moving mechanism, the optical cable pushes the arc plate in the moving mechanism to move towards the inner wall of the limiting plate to stir the water-blocking grease, and the water-blocking grease between the arc plate and the twisted section is coated on the surface of the twisted section.

[0012] When the straight section of the optical cable passes through the moving mechanism, the arc plate in the moving mechanism returns to its initial state to press and coat the water-blocking grease between the arc plate and the straight section onto the surface of the straight section.

[0013] In one optional implementation, the movable mechanism includes: a fixed block and a movable block;

[0014] The fixed block is disposed on the inner wall of the limiting tube, and a sliding groove is provided on the side of the fixed block near the axis of the limiting tube, and the movable block is slidably disposed in the sliding groove;

[0015] An arc-shaped plate is provided on the outer wall of the movable block near the axis of the limiting tube;

[0016] When the curved plate is in its initial state, the side walls of adjacent curved plates are in contact, and the curved plates form a cylinder.

[0017] In one optional embodiment, a protrusion is provided on the side of the movable block near the axis of the limiting tube, the protrusion being adapted to a recess on the outer wall of the optical cable and inserted into the recess;

[0018] The length of the arc-shaped plate along its axial direction is greater than the length of the protrusion.

[0019] In one optional embodiment, when the optical cable moves, when the concave part of the twisted section of the optical cable passes the protrusion, the optical cable is in a rotating state. The concave part pushes the protrusion to move away from the axis of the limiting tube, which drives the movable block to move towards the inner wall of the limiting tube and retract into the concave part, so as to drive the arc plate to move towards the inner wall of the limiting tube and stir the water-blocking grease between the arc plate and the inner wall of the limiting tube.

[0020] When the protrusion moves to the corresponding recess of the straight section of the optical cable, the optical cable does not rotate, the arc plate returns to its initial state, the straight section passes through the cylinder, and the water-blocking grease between the arc plate and the straight section is pressed and coated on the surface of the straight section.

[0021] In one alternative embodiment, a spring is connected between the movable block and the inner wall of the sliding groove so that the movable block is reset by the spring after movement.

[0022] In one optional embodiment, the limiting tube is fixedly mounted on the mounting bracket;

[0023] The outer wall of the limiting tube is provided with a feed port, which is connected to the filling cavity;

[0024] The mounting frame is provided with a flow channel that communicates with the feed inlet.

[0025] In one alternative embodiment, a feeding device is provided on one side of the mounting frame, the feeding device being configured to deliver water-blocking grease into the flow channel so that the water-blocking grease flows into the filling cavity through the inlet.

[0026] In one optional embodiment, the feeding device includes: a second material cylinder;

[0027] The second material cylinder is disposed on one side of the mounting frame and is connected to the flow channel in the mounting frame through the first pipe, so that the water-blocking grease in the second material cylinder flows into the flow channel through the first pipe and into the filling cavity through the feed port.

[0028] In one alternative embodiment, the second material cylinder is connected to the pump body via a second pipe, and the pump body is connected to the first material cylinder;

[0029] The pump body is configured to draw water-blocking grease from the first barrel into the second barrel through the second pipe.

[0030] Secondly, this disclosure also provides a method for using the above-described stranded optical cable grease filling device, comprising:

[0031] When the twisted section of the optical cable passes through the moving mechanism, the optical cable pushes the arc plate in the moving mechanism to move towards the inner wall of the limiting plate to stir the water-blocking grease, and the water-blocking grease between the arc plate and the twisted section is coated on the surface of the twisted section.

[0032] When the straight section of the optical cable passes through the moving mechanism, the arc plate in the moving mechanism returns to its initial state to press and coat the water-blocking grease between the arc plate and the straight section onto the surface of the straight section.

[0033] The beneficial effects of this invention are as follows: the stranded optical cable grease filling device includes: a filling device configured to coat the outside of the optical cable with water-blocking grease; the filling device includes: a limiting tube; the optical cable is inserted into the limiting tube, and a filling cavity is formed between the outer wall of the optical cable and the inner wall of the limiting tube, the filling cavity being filled with water-blocking grease; a plurality of movable mechanisms are equidistantly arranged along the circumferential direction on the inner wall of the limiting tube; when the twisted section of the optical cable passes through the movable mechanism, the optical cable pushes the arc plate in the movable mechanism to move towards the inner wall of the limiting plate to agitate the water-blocking grease, and the water-blocking grease between the arc plate and the twisted section is coated on the surface of the twisted section; when the straight section of the optical cable passes through the movable mechanism, the arc plate in the movable mechanism returns to its initial state to press the water-blocking grease between the arc plate and the straight section onto the surface of the straight section, thereby achieving uniform coating of water-blocking grease on the surface of the straight section of the optical cable.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0050] During the production process, bidirectional alternating stranded optical cables require the coating of water-blocking grease on their surface. Along the length of the cable, some sections are twisted (called "twisted sections"), while others are straight (called "straight sections"). The straight sections are located between two twisted sections. During coating, the twisted sections rotate, causing the water-blocking grease within the coating area to be pushed away from the cable. When the straight sections move into the coating area, the cable stops rotating. At this point, due to the inertia caused by the rotation of the twisted sections moving the water-blocking grease away from the cable, the grease cannot be evenly coated on the surface of the straight sections.

[0051] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0053] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] like Figure 1 , Figure 2 and Figure 4 As shown, at least one disclosed embodiment provides a stranded optical cable grease filling device, comprising: a filling device 1 configured to coat the outer surface of an optical cable 4 with water-blocking grease; the filling device 1 includes: a limiting tube 11; the optical cable 4 is inserted into the limiting tube 11, and a filling cavity 13 is formed between the outer wall of the optical cable 4 and the inner wall of the limiting tube 11, the filling cavity 13 being filled with water-blocking grease; a plurality of movable mechanisms 12 are equidistantly arranged along the circumferential direction on the inner wall of the limiting tube 11; when the twisted section 41 of the optical cable 4 passes through the movable mechanism 12... When the optical cable 4 pushes the arc plate 123 in the moving mechanism 12 to move towards the inner wall of the limiting plate, it stirs the water-blocking grease and the water-blocking grease between the arc plate 123 and the twisted section 41 is coated on the surface of the twisted section 41. When the straight section 42 of the optical cable 4 passes through the moving mechanism 12, the arc plate 123 in the moving mechanism 12 returns to its initial state to press the water-blocking grease between the arc plate 123 and the straight section 42 onto the surface of the straight section 42, thereby achieving uniform coating of water-blocking grease on the surface of the straight section 42 of the optical cable 4.

[0055] In this embodiment, optical cable 4 is a bidirectional alternating stranded optical cable.

[0056] like Figure 2 and Figure 3 As shown, in an optional embodiment, the movable mechanism 12 includes: a fixed block 121 and a movable block 122; the fixed block 121 is disposed on the inner wall of the limiting tube 11, and a sliding groove 125 is formed on the side of the fixed block 121 near the axis of the limiting tube 11, and the movable block 122 is slidably disposed in the sliding groove 125; an arc-shaped plate 123 is disposed on the outer wall of the movable block 122 near the axis of the limiting tube 11; when the arc-shaped plate 123 is in the initial state, the side walls of adjacent arc-shaped plates 123 are in contact, and the arc-shaped plates 123 form a cylinder.

[0057] In this embodiment, the outer wall of the movable block 122 can contact the inner wall of the sliding groove 125 to prevent water-resistant grease from entering the sliding groove 125 and to prevent the water-resistant grease from hindering the movement of the movable block 122.

[0058] In one optional embodiment, the movable block 122 is provided with a protrusion 124 on one side near the axis of the limiting tube 11. The protrusion 124 is adapted to the recess 43 on the outer wall of the optical cable 4 and is inserted into the recess 43. The length of the arc plate 123 in the axial direction is greater than the length of the protrusion 124.

[0059] In this embodiment, the length of the arc plate 123 is greater than the length of the protrusion 124, so that when the optical cable 4 moves, after the corresponding position of the recess 43 passes the protrusion 124, the water-blocking grease in the subsequent space of the filling cavity 13 can enter the recess 43 to coat the surface of the optical cable 4 and ensure the coating effect.

[0060] like Figure 5 and Figure 6 In one optional embodiment, when the optical cable 4 moves, when the twisted segment 41 of the optical cable 4 corresponds to the recess 43 and passes the protrusion 124, the optical cable 4 is in a rotating state. The recess 43 pushes the protrusion 124 to move away from the axis of the limiting tube 11, so that the protrusion 124 moves out of the recess 43, and drives the movable block 122 to move towards the inner wall of the limiting tube 11 and retract into the recess 43, so as to drive the arc plate 123 to move towards the inner wall of the limiting tube 11, and stir the water-blocking grease between the arc plate 123 and the inner wall of the limiting tube 11. When the protrusion 124 moves to the recess 43 corresponding to the straight segment 42 of the optical cable 4, the optical cable 4 does not rotate, the arc plate 123 returns to the initial state, the straight segment 42 passes through the cylinder, and the water-blocking grease between the arc plate 123 and the straight segment 42 is pressed and coated on the surface of the straight segment 42.

[0061] In this embodiment, when the arc plate 123 moves away from the axis of the limiting tube 11, it can stir the water-blocking grease to prevent the water-blocking grease from accumulating on the inner wall of the limiting tube 11 and to prevent the accumulated water-blocking grease from solidifying, thereby avoiding the impact on the surface coating of the optical cable 4.

[0062] In this embodiment, since the inner diameter of the cylinder is smaller than the inner diameter of the limiting tube 11, the arc plate 123 can push the water-blocking grease between the arc plate 123 and the surface of the straight section 42 during the resetting process. This increases the pressure on the water-blocking grease, allowing it to be better coated on the surface of the straight section 42 and improving the uniformity of the coating on the surface of the straight section 42. The inner diameter of the cylinder is larger than the maximum diameter of the optical cable 4.

[0063] like Figure 3 As shown, in an optional embodiment, a spring 126 is connected between the movable block 122 and the inner wall of the sliding groove 125 so that the movable block 122 is reset by the spring 126 after it has moved.

[0064] In this embodiment, the number of springs 126 provided in each movable mechanism 12 can be multiple, so that the movable block 122 can be reset better.

[0065] like Figure 1 As shown, in one optional embodiment, the limiting tube 11 is fixedly mounted on the mounting frame 2; the outer wall of the limiting tube 11 is provided with a feed inlet 111, which communicates with the filling cavity 13; the mounting frame 2 is provided with a flow channel communicating with the feed inlet 111.

[0066] In one alternative embodiment, a feeding device 3 is provided on one side of the mounting frame 2. The feeding device 3 is configured to deliver water-blocking grease into the flow channel so that the water-blocking grease flows into the filling cavity 13 through the feed port 111.

[0067] In one optional embodiment, the feeding device 3 includes a second material cylinder 31; the second material cylinder 31 is disposed on one side of the mounting frame 2 and is connected to the flow channel in the mounting frame 2 through a first pipe 32, so that the water-blocking grease in the second material cylinder 31 flows into the flow channel through the first pipe 32 and flows into the filling cavity 13 through the feed inlet 111.

[0068] In one alternative embodiment, the second material cylinder 31 is connected to the pump body 34 via the second pipe 33, and the pump body 34 is connected to the first material cylinder 35; the pump body 34 is configured to draw water-blocking grease from the first material cylinder 35 into the second material cylinder 31 via the second pipe 33.

[0069] In this embodiment, another pump body 34 can be installed inside the second material cylinder 31 to pump the water-blocking grease in the second material cylinder 31 into the limiting cylinder through the first pipe 32.

[0070] At least one other disclosed embodiment also provides a method of operation using the above-described stranded optical cable grease filling device, comprising: when the twisted segment 41 of the optical cable 4 passes through the movable mechanism 12, the optical cable 4 pushes the arc plate 123 in the movable mechanism 12 to move towards the inner wall of the limiting plate to agitate the water-blocking grease, and the water-blocking grease between the arc plate 123 and the twisted segment 41 is coated on the surface of the twisted segment 41; when the straight segment 42 of the optical cable 4 passes through the movable mechanism 12, the arc plate 123 in the movable mechanism 12 returns to its initial state to press the water-blocking grease between the arc plate 123 and the straight segment 42 onto the surface of the straight segment 42.

[0071] In summary, the cable grease filling equipment for this layer of twisted optical cable includes: a filling device 1, configured to coat the outer surface of the optical cable 4 with water-blocking grease; the filling device 1 includes: a limiting tube 11; the optical cable 4 is inserted into the limiting tube 11, and a filling cavity 13 is formed between the outer wall of the optical cable 4 and the inner wall of the limiting tube 11, the filling cavity 13 being filled with water-blocking grease; a plurality of movable mechanisms 12 are equidistantly arranged along the circumference of the inner wall of the limiting tube 11; when the twisted section 41 of the optical cable 4 passes through the movable mechanism 12, the optical cable 4 is pushed... The arc plate 123 in the moving mechanism 12 moves towards the inner wall of the limiting plate to agitate the water-blocking grease, and the water-blocking grease between the arc plate 123 and the twisted section 41 is coated on the surface of the twisted section 41; when the straight section 42 of the optical cable 4 passes through the moving mechanism 12, the arc plate 123 in the moving mechanism 12 returns to its initial state to press the water-blocking grease between the arc plate 123 and the straight section 42 onto the surface of the straight section 42, thereby achieving uniform coating of water-blocking grease on the surface of the straight section 42 of the optical cable 4.

[0072] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0073] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0074] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0075] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0076] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
