Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cables, in particular to a water-tight cable conductor fine twisting and glue injection equipment. BACKGROUND

[0002] At present, in the cable manufacturing industry, water-tight cables are widely used in underwater engineering, shipbuilding, ocean exploration and other fields due to their excellent waterproof performance and electrical performance.

[0003] The twisting of the cable refers to the process of twisting a plurality of single wires (usually metal conductors such as copper, aluminum, etc.) in a spiral according to certain rules and ways to form an integral conductor structure.

[0004] Twisting a plurality of single wires improves the overall mechanical strength of the cable, making it more capable of withstanding external pulling and extrusion. Twisting can make the electric field distribution inside the cable more uniform, reducing the electric field concentration phenomenon, thereby reducing the capacitance and inductance of the cable and improving the transmission performance of the cable. However, there are still gaps between adjacent single wires of the twisted cable, and when subjected to external forces such as stretching, bending and twisting, the single wires cannot bear force cooperatively and are prone to relative displacement, leading to local deformation or even damage of the cable and affecting its mechanical strength and reliability. SUMMARY

[0005] In order to reduce the gap between adjacent single wires of the twisted cable and improve the overall mechanical strength of the cable, the application provides a water-tight cable conductor fine twisting and glue injection equipment.

[0006] The water-tight cable conductor fine twisting and glue injection equipment provided by the application adopts the following technical scheme:

[0007] A water-tight cable conductor fine twisting and glue injection equipment, comprising a pay-off stand, a traction assembly and a drive shaft rotating along its central axis, the drive shaft penetrating through the center of the pay-off stand and being fixedly connected with the pay-off stand, a wire guide disc being fixed at one end of the drive shaft, the wire guide disc being located between the traction assembly and the pay-off stand, a plurality of wire guide holes being formed in the wire guide disc, adjacent wire guide holes being arranged at intervals; further comprising a compression mold, the compression mold comprising a compression seat and a compression disc, the compression seat being fixed between the traction assembly and the wire guide disc, the compression disc being rotatably arranged on the compression seat with the rotation axis being horizontally arranged; a compression hole being formed in the compression disc, the diameter of the compression hole gradually decreasing in the direction from the wire guide disc to the traction assembly; the traction assembly being used for pulling out the single wire from the pay-off stand.

[0008] By adopting the technical scheme, before work, the single-wire winding shaft is placed on the pay-off rack, and the line head of each single wire is sequentially threaded through the corresponding guide hole and the compression hole, and is connected with the traction assembly. When working, the traction assembly is started, and the driving shaft is driven to rotate by an external device. Since the driving shaft is fixedly connected with the pay-off rack and rotates around the central axis, the pay-off rack is synchronously rotated, and the guide disc guides the multiple single wires to be twisted in a spiral shape before passing through the compression hole. The twisted cable passes through the corresponding compression hole, and as the diameter of the compression hole gradually decreases, a continuous and gradually increasing mechanical extrusion force is generated on the twisted cable, which causes the single wires in the cable to approach each other and tightly adhere to each other, thereby effectively reducing the gap between the adjacent single wires of the twisted cable and improving the overall mechanical strength of the cable.

[0009] Optionally, the compression hole is provided with a plurality of compression holes and is arranged at intervals on the compression disc, and the center points of all the compression holes are connected in a circular shape with the center of the circle located on the rotating shaft of the compression disc and the compression seat. The minimum diameters of the adjacent compression holes decrease in turn.

[0010] By adopting the technical scheme, the compression disc can be rotated according to the diameters of the cables twisted by different numbers of single wires, and different diameters of the compression holes are used to meet the diversified production needs.

[0011] Optionally, the pay-off rack is provided with an auxiliary wire disc on the side away from the guide disc, the auxiliary wire disc is rotatably connected with the pay-off rack and the rotating shaft of the auxiliary wire disc is horizontally arranged, a counterweight is fixedly arranged at the bottom end of the auxiliary wire disc, and an auxiliary wire rack for carrying a fiber wire reel is fixedly arranged on the auxiliary wire disc.

[0012] By adopting the technical scheme, the auxiliary wire disc can add fiber wires or other reinforcing materials during the twisting process of the cable. The fiber wires can fill the gaps between the single wires during the twisting process and tightly combine with the single wires, thereby reducing the gap between the adjacent single wires of the twisted cable. The design of the counterweight ensures the smooth rotation of the auxiliary wire disc, avoids uneven distribution of the fiber wires, further ensures the tight adhesion between the single wires and the fiber wires, and improves the overall compactness of the cable.

[0013] Optionally, the guide disc is provided with a force measuring assembly, the force measuring assembly comprises a roller, a first gasket, a first spring, a warning light, a battery, and a first force measuring cylinder, the first force measuring cylinder is fixedly arranged on the outer wall of the guide disc, the first spring is arranged in the first force measuring cylinder and one end of the first spring is fixedly connected with the first gasket, the other end of the first spring is fixedly connected with the inner wall of the sealing end of the first force measuring cylinder, the battery is fixedly arranged on the inner wall close to the opening end of the first force measuring cylinder, the warning light is turned on when the first gasket abuts against the battery, the first gasket slides in the direction close to or away from the battery, one end of the roller body is fixedly connected with the first gasket, and the roller rolls against the single wire passing through the guide hole.

[0014] By adopting the technical scheme, the force measuring assembly can monitor whether each single wire is in a tension state during the stranding process in real time, when the tension of the single wire is too small, the first spring pushes the first gasket to abut against the battery, and the warning light is turned on, which can timely remind the operator to make adjustment, so as to avoid the gap between the single wires in the cable after stranding due to the untensioned single wire. By accurately controlling the tension of the single wire, it can be ensured that the single wire is closely attached during the stranding process, thereby reducing the gap between the adjacent single wires.

[0015] Optionally, a line splitting ring is fixed on the drive shaft, the center line of the line splitting ring coincides with the center line of the drive shaft, a plurality of guide tubes for changing the bending degree of the single wire from the pay-off stand to the guide drum are arranged on the line splitting ring, the guide tubes are threadedly connected with the line splitting ring, and the single wire penetrates through the guide tubes.

[0016] By adopting the technical scheme, the line splitting ring and the guide tube can adjust the threading path of the single wire before stranding, so as to ensure that each single wire is in a tension state when entering the stranding area, and when the single wire is in a loose state, the guide tube is adjusted to extend the bending degree of the single wire from the pay-off stand to the guide drum, so as to achieve the effect of extending the threading path, and finally achieve the effect of tensioning the single wire. By optimizing the threading path of the single wire, the stress concentration phenomenon of the single wire during the stranding process can be reduced, so that the single wire can be more evenly arranged during stranding, thereby reducing the gap between the adjacent single wires in the cable after stranding.

[0017] Optionally, the cable stranding device further comprises a glue applying assembly, the glue applying assembly comprises a glue applying box, a storage barrel and a glue applying head, the glue applying box is fixed on the side of the traction assembly away from the guide drum; the storage barrel is vertically fixed on the top of the glue applying box, the bottom end of the storage barrel extends into the glue applying box and is fixedly connected with the glue applying head, the inside of the glue applying head is in communication with the inside of the storage barrel; the glue applying head is annular and the inner wall thereof is provided with a glue applying hole; a screw rod is rotatably arranged in the storage barrel, the screw rod rotates relative to the storage barrel, and a screw conveyor is fixed to the screw rod close to the glue applying head, and the edge of the screw conveyor slidably abuts against the inner wall of the storage barrel.

[0018] By adopting the technical scheme, the glue applying assembly can inject glue pressure into the inside of the cable after the cable stranding is completed, the glue can fill the gap between the single wires and solidify, so that the single wires are closely combined. The design of the screw rod and the screw conveyor ensures that the glue is sprayed with pressure, and through the glue injection treatment, the single wires in the inside of the cable can be more closely attached, thereby significantly reducing the gap between the adjacent single wires.

[0019] Optionally, a glue scraping ring is fixed in the glue applying box, the center line of the glue scraping ring coincides with the center line of the glue applying head; and along the cable penetration direction, the glue scraping ring is located behind the glue applying head.

[0020] By adopting the technical scheme, the glue scraping ring can scrape off the excess glue after the cable is glued, so as to ensure that the external shape of the cable is regular.

[0021] Optionally, the screw is provided with a push plate, the push plate is located above the auger, the push plate is threadedly connected with the screw, and the edge of the push plate is in sliding abutment with the inner wall of the storage barrel and reciprocally slides in the vertical direction.

[0022] By adopting the above technical scheme, the auger rotates under the driving of the screw, and since the auger is in sliding abutment with the inner wall of the glue injection pipeline, the auger generates an axial pushing force on the glue when rotating. The screw structure of the auger causes the glue to be continuously extruded and transported during being pushed, which is an important source of the pressure in the glue injection pipeline. The push plate is threadedly connected with the screw, and when the screw rotates, the push plate slides along the length direction of the glue injection pipeline. The push plate directly applies pressure to the glue during advancing, and pushes the glue to move forward, which is another source of the pressure in the glue injection pipeline.

[0023] Optionally, a pressure regulating pipe is communicated between the storage barrel and the glue applying head, the pressure regulating pipe is L-shaped, and a switch assembly for forming a passage in the pressure regulating pipe when the internal pressure of the pressure regulating pipe reaches a set value and slowly closing the passage in the pressure regulating pipe when the internal pressure of the pressure regulating pipe is lower than the set value is arranged on the pressure regulating pipe.

[0024] By adopting the above technical scheme, the passage is opened only when the pressure reaches the set value to allow the glue solution to pass, so that the pressure when the glue applying head sprays the glue solution is stable and meets the requirements, which is beneficial to ensuring the uniformity and stability of glue injection and better filling the gap between adjacent single wires in the cable, and improves the glue injection quality. When the pressure is lower than the set value, the passage is slowly closed to avoid interruption of glue solution transportation or sudden pressure drop. This dynamic adjustment mechanism can ensure that the glue solution always maintains a stable pressure during glue injection, so that the gap between the single wires in the cable is more uniformly filled. Compared with the conventional valve that controls the opening and closing of the passage in the pressure regulating pipe, the opening time interval of the conventional valve has hysteresis, which causes the glue solution pressure to fluctuate and affects the filling effect at the initial stage of glue application.

[0025] Optionally, a collection pool is fixed in the glue applying box and covers the area below the glue scraping ring and the glue applying head.

[0026] By adopting the above technical scheme, the collection pool can collect the excess glue water scraped by the glue scraping ring and the glue water dripping during glue application, and avoids waste of glue water.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] Through the design of the compression mold, the hole diameter of the compression hole gradually decreases, continuously increasing the mechanical extrusion force on the twisted cable, causing the individual wires to move closer to each other and tightly adhere to each other, thereby significantly reducing the gap between adjacent individual wires. At the same time, the setting of the auxiliary wire disc allows the addition of fiber wires during the twisting process, further filling the gap and enhancing the overall compactness of the cable. This design not only improves the mechanical strength of the cable, but also enhances its tensile performance and durability;

[0029] The force measuring assembly monitors the tension of the individual wires in real time during the twisting process, ensuring that each individual wire is in a tensioned state, avoiding the generation of gaps due to the relaxation of individual wires;

[0030] The glue coating assembly dynamically adjusts the glue injection pressure through the switch assembly, ensuring that the glue solution is injected into the cable with stable pressure, uniformly filling the gap between the individual wires. This precise control mechanism effectively improves the compactness and consistency of the cable, avoiding quality problems caused by uneven tension or fluctuating glue injection pressure.
