Description

Technical Field

[0001] The invention belongs to the technical field of special equipment for manufacturing conductors or cables, and in particular relates to a layer-twisted optical cable paste filling device and a working method thereof. Background Art

[0002] During the production process, the bidirectional alternately twisted layer-stranded optical cable needs to be coated with water-blocking grease on its surface. Some sections in the length direction of the bidirectional alternately twisted layer-stranded optical cable are twisted in a twisted shape, which is a twisted section, and some sections are straight in a straight shape, which is a straight section. The section between the two twisted sections is a straight section. The twisted section is in a rotating state during coating, which will cause the water-blocking grease in the coating area to be pushed away from the bidirectional alternately twisted layer-stranded optical cable. When the straight section moves into the coating area, the bidirectional alternately twisted layer-stranded optical cable does not rotate. At this time, due to the inertia of the water-blocking grease moving away from the bidirectional alternately twisted layer-stranded optical cable caused by the previous rotation of the twisted section, the water-blocking grease cannot be evenly coated on the surface of the straight section.

[0003] Therefore, when the straight section of the bidirectional alternately twisted layer-twisted optical cable is coated with water-blocking grease, the water-blocking grease cannot be evenly coated on the surface of the straight section due to the inertia of the previous rotation of the twisted section causing the water-blocking grease to move away from the bidirectional alternately twisted layer-twisted optical cable. Therefore, it is necessary to design a cable grease filling device for layer-twisted optical cables and its working method.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0024] During the production process, the bidirectional alternately twisted layer-stranded optical cable needs to be coated with water-blocking grease on its surface. Some sections in the length direction of the bidirectional alternately twisted layer-stranded optical cable are twisted in a twisted shape, which is a twisted section, and some sections are straight in a straight shape, which is a straight section. The section between the two twisted sections is a straight section. The twisted section is in a rotating state during coating, which will cause the water-blocking grease in the coating area to be pushed away from the bidirectional alternately twisted layer-stranded optical cable. When the straight section moves into the coating area, the bidirectional alternately twisted layer-stranded optical cable does not rotate. At this time, due to the inertia of the water-blocking grease moving away from the bidirectional alternately twisted layer-stranded optical cable caused by the previous rotation of the twisted section, the water-blocking grease cannot be evenly coated on the surface of the straight section.

[0025] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0028] like Figure 1 、 Figure 2 and Figure 4As shown, at least one disclosed embodiment provides a cable grease filling device for a twisted optical cable, comprising: a filling device 1, which is configured to apply water-blocking grease to the outside of an optical cable 4; the filling device 1 comprises: a limiting tube 11; an optical cable 4 is passed through the limiting tube 11, a filling cavity 13 is formed between the outer wall of the optical cable 4 and the inner wall of the limiting tube 11, and the filling cavity 13 is filled with water-blocking grease; a plurality of movable mechanisms 12 are equidistantly arranged on the inner wall of the limiting tube 11 along the circumferential direction; when the twisted section 41 of the optical cable 4 passes through the movable mechanism 12 When the straight section 42 of the optical cable 4 passes through the movable mechanism 12, the curved plate 123 in the movable mechanism 12 returns to its initial state to press the water-blocking grease between the curved plate 123 and the straight section 42 and coat it on the surface of the straight section 42, thereby achieving uniform coating of the water-blocking grease on the surface of the straight section 42 of the optical cable 4.

[0029] In this embodiment, the optical cable 4 is a bidirectional alternately twisted layer optical cable.

[0030] 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 arranged on the inner wall of the limiting tube 11, and a sliding groove 125 is provided on the side close to the axis of the limiting tube 11, and the movable block 122 is slidably arranged in the sliding groove 125; an arc plate 123 is provided on the outer wall of the movable block 122 close to the axis of the limiting tube 11; when the arc plate 123 is in the initial state, the side walls of adjacent arc plates 123 are in contact, and the arc plate 123 forms a cylinder.

[0031] In this embodiment, the outer wall of the movable block 122 can contact the inner wall of the sliding groove 125 to prevent the water-blocking grease from entering the sliding groove 125 and hindering the movement of the movable block 122 .

[0032] In an optional embodiment, a protrusion 124 is provided on a surface of the movable block 122 close to the axis of the limiting tube 11, and the protrusion 124 is adapted to the recess 43 on the outer wall of the optical cable 4 and 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.

[0033] 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 and coat the surface of the optical cable 4 to ensure the coating effect.

[0034] like Figure 5 and Figure 6 As shown in an optional embodiment, when the optical cable 4 moves, when the corresponding recess 43 of the twisted section 41 of the optical cable 4 passes through the protrusion 124, the optical cable 4 is in a rotating state, and 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, driving the movable block 122 to move toward the inner wall of the limiting tube 11 and retract into the recess 43, so as to drive the arc plate 123 to move toward the inner wall of the limiting tube 11, stirring 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 corresponding recess 43 of the straight section 42 of the optical cable 4, the optical cable 4 does not rotate, the arc plate 123 returns to its initial state, the straight section 42 passes through the cylinder, and the water-blocking grease between the arc plate 123 and the straight section 42 is pressed and coated on the surface of the straight section 42.

[0035] In this embodiment, when the arc plate 123 moves away from the axis of the limiting tube 11, the water-blocking grease can be stirred to prevent the water-blocking grease from accumulating on the inner wall of the limiting tube 11, to prevent the accumulated water-blocking grease from solidifying, and thereby to avoid affecting the surface coating of the optical cable 4.

[0036] In this embodiment, because the inner diameter of the cylinder is smaller than that of the limiting tube 11, the curved plate 123 can push the water-blocking grease between the curved plate 123 and the surface of the straight section 42 during the resetting process, thereby increasing the pressure on the water-blocking grease, better coating 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.

[0037] 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 moving.

[0038] 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.

[0039] like Figure 1 As shown, in an optional embodiment, the limiting tube 11 is fixedly set on the mounting frame 2; a feed port 111 is opened on the outer wall of the limiting tube 11, and the feed port 111 is connected to the filling cavity 13; a flow channel connected to the feed port 111 is set in the mounting frame 2.

[0041] In an optional embodiment, the loading device 3 includes: a second barrel 31; the second barrel 31 is arranged 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 paste in the second barrel 31 flows into the flow channel through the first pipe 32, and flows into the filling cavity 13 through the feed port 111.

[0042] In an optional embodiment, the second barrel 31 is connected to the pump body 34 through the second pipe 33, and the pump body 34 is connected to the first barrel 35; the pump body 34 is configured to draw the water-blocking paste in the first barrel 35 into the second barrel 31 through the second pipe 33.

[0043] In this embodiment, another pump body 34 may be provided in the second barrel 31 , so that the water-blocking paste in the second barrel 31 can be fed into the limiting barrel through the first pipe 32 via the pump body 34 .

[0044] At least one other disclosed embodiment also provides a working method using the above-mentioned twisted optical cable cable grease filling device, including: when the twisted section 41 of the optical cable 4 passes through the movable mechanism 12, the optical cable 4 pushes the curved plate 123 in the movable mechanism 12 to move toward the inner wall of the limiting plate to stir the water-blocking grease, and the water-blocking grease between the curved 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 movable mechanism 12, the curved plate 123 in the movable mechanism 12 returns to its initial state to press the water-blocking grease between the curved plate 123 and the straight section 42 and coat it on the surface of the straight section 42.
