Description

Technical Field

[0001] The present invention relates to the technical field of cable production equipment, and in particular to a cable shielding layer braiding device. Background Art

[0002] In the cable production process, the weaving process of the cable shielding layer is a key link to ensure the electromagnetic shielding performance. Its core lies in forming a continuous and uniform conductive layer by interweaving metal wires to suppress electromagnetic interference and radio frequency interference.

[0003] Generally speaking, the basic process of cable shield braiding can be summarized as follows: first, preparatory work is carried out, including checking equipment and tools, preparing cables and shielding materials, and determining shielding requirements; then the cables are pre-processed, such as cleaning and cutting; then the braided mesh and other shielding materials are tightly attached to the cable and fixed with tools such as tape and clips; then grounding is carried out to ensure that the shielding material is firmly connected to the grounding system; finally, an appearance inspection and performance test are carried out to ensure that the shielding effect meets the design requirements, and finishing work is completed, including cleaning the site, recording information, and labeling and packaging.

[0004] Based on this, the Chinese patent document with publication number CN114334285A discloses an automatic cable production braiding machine, which, when braiding the cable to a fixed length, fixes one end of the wire by rotating the table, fixes the other end of the wire by a clamping mechanism, and keeps the wire in a tensioned state at all times by the elastic force of the supporting spring. At the same time, the wire is guided by the movable circular plate, which further improves the tensioning effect of the wire and avoids the loosening of the wire during the braiding process, thereby ensuring the forming effect of the cable. In the process of braiding the wire by this braiding equipment, each wire is evenly arranged along the axis. During the rotation of one end of the wire, the wire is separated by the movable circular plate. As the movable circular plate moves at a constant speed from the rotating table to the fixed circular plate, each wire is gradually and evenly wound together from the rotating table to the fixed circular plate, ensuring the uniform winding density of the wire at various locations on the cable.

[0005] However, the cable arrangement and braiding machines disclosed in the prior art still have the technical problem of being unable to perform online braiding of the shielding layer on the surface of the insulation layer. Specifically, the structure of a cable with a shielding layer generally includes a wire core, an insulation layer, a shielding layer, and a sheath. Typically, cable manufacturers need to first produce the wire core, and then cover the insulation layer on the surface of the wire core through a continuous extrusion process. Then, metal wires, such as tinned copper wires, are arranged through the spindles of the braiding machine, and the spindle rotation trajectory is controlled so that the metal wires are staggered at an angle, generally between 30° and 60°, so that the metal wires can be evenly braided on the surface of the insulation layer. However, the cable arrangement and braiding equipment disclosed in the prior art can only braid cables to a fixed length and cannot perform online braiding production on the surface of the insulation layer.

[0025] Please also refer to Figures 1 to 2 The present invention provides a cable shielding layer braiding device comprising: a driving mechanism 1, an output gear set 2, a transmission gear set 3, a core guide portion 4, a cross capstan frame 5, a central gear set 6, a planetary gear 7, a rotating bracket 8, a wire storage drum 9, a cross wire drawing frame 10 and a roller set 11; the driving mechanism 1 is connected to the output gear set 2 in a driving manner, and the output gear set 2 is meshed with the transmission gear set 3; the core guide portion 4 is inserted into the transmission gear set 3 and the cross capstan frame 5, and the transmission gear set 3 is meshed with the roller set 11. The cross winch frame 5 is connected; the central gear set 6 is meshed with the output gear set 2, and the four planetary gears 7 are arranged around the periphery of the central gear set 6, and each of the planetary gears 7 is meshed with the central gear set 6; each of the planetary gears 7 is correspondingly connected to the central gear set 6; each of the planetary gears 7 is driven by a rotating bracket 8, and each of the rotating brackets 8 is movably provided with a wire storage drum 9; the cross pulley frame 10 is connected to the cross winch frame 5, and the roller group 11 is adjacent to the cross pulley frame 10.

[0026] Specifically, when a cable shielding layer braiding device of the present invention is in working mode, the insulating layer material containing the wire core inside is introduced into the core guide part 4 under the traction action of the external traction mechanism, and passes through the transmission gear group 3, the center gear group 6, the cross capstan frame 5, and the cross wire drawing frame 10 in turn, and then passes out from the cross wire drawing frame 10 and enters the roller group 11; at this time, the driving mechanism 1 drives the output gear group 2 to operate, so that the output gear group 2 drives the transmission gear group 3 and the center gear group 6 respectively through meshing transmission. When the transmission gear set 3 is driven, it can drive the cross capstan frame 5 to rotate at a first preset speed; and when the central gear set 6 is driven, it can drive each of the planetary gears 7 to rotate at a second preset speed, and make the rotating bracket 8 connected to each of the planetary gears 7 driven to rotate around the central axis of the rotating bracket 8; thereby, the storage drum 9 can rotate around the central axis of the rotating bracket 8 while also revolving along the outer contour of the central gear set 6; the metal wire pre-stored on the storage drum 9 can be pulled out before the storage drum 9 is moved and pass through the preset position of the cross wire drawing frame 10, and then be wound on the surface of the insulating layer pulled out from the center of the cross wire drawing frame 10; thereafter, when the insulating layer passes through the roller set 11, the metal wire pulled out of each of the storage drums 9 can be woven into layers on the surface of the insulating layer alternately at a preset angle. It can be seen that the wire storage drum 9 rotates on its own under the drive of the planetary gear 7, and at the same time, revolves according to a preset circular trajectory under the drive of the cross capstan frame 5. As a result, multiple groups of metal wires can be alternately woven into layers on the surface of the insulating layer at the same time. Compared with the existing technology, this weaving method can obtain a denser shielding layer and can realize rapid molding of the shielding layer; therefore, a cable shielding layer weaving device of the present invention solves the technical problem of how to improve the weaving efficiency of the shielding layer.

[0027] Furthermore, the driving mechanism 1 includes a driving motor 101 , a driving shaft 102 and a coupling 103 ; the driving motor 101 is drivingly connected to the driving shaft 102 , and the driving shaft 102 is connected to the coupling 103 .

[0028] Furthermore, the output gear set 2 has an output power shaft 201, a first output gear 202 and a second output gear 203; the coupling 103 connects the drive shaft 102 and the output power shaft 201 respectively; the first output gear 202 and the second output gear 203 are respectively connected to the two ends of the output power shaft 201.

[0029] Furthermore, the transmission gear set 3 has a first transmission gear 301 and a transmission shaft 302; the first transmission gear 301 is meshed and connected with the first output gear 202, the first transmission gear 301 is connected to the transmission shaft 302, and the transmission shaft 302 is connected to the cross capstan frame 5; the core guide portion 4 is inserted into the transmission shaft 302.

[0030] Furthermore, the core guide portion 4 can be a guide tube structure, which is hollow inside to facilitate the passage of materials such as the wire core and the insulation layer through its inner cavity; and the core guide portion 4 is inserted into the transmission shaft 302 and other components.

[0031] Furthermore, the cross winch frame 5 comprises a central connecting sleeve 501, swing arms 502, and edge connecting sleeves 503. The central connecting sleeve 501 is connected to the transmission shaft 302, and four swing arms 502 are evenly distributed and connected to the periphery of the central connecting sleeve 501. The end of each swing arm 502 is connected to an edge connecting sleeve 503. The four swing arms 502 are arranged in a "cross" shape, with the central connecting sleeve 501 as the connection center.

[0032] Furthermore, the center gear set 6 has a center gear sleeve 601, a second transmission gear 602 and a center gear 603; the center gear sleeve 601 is adjacent to the center connecting sleeve 501 and is connected to the transmission shaft 302, and the second transmission gear 602 and the center gear 603 are respectively connected to the two ends of the center gear sleeve 601; the second transmission gear 602 is meshed with the second output gear 203, and the center gear 603 is respectively meshed with each of the planetary gears 7.

[0033] Furthermore, the rotating bracket 8 has a rotating shaft 801 and a rotating fork 802; one rotating shaft 801 is movably sleeved in one of the edge connecting sleeves 503, one end of each rotating shaft 801 is connected to one of the planetary gears 7, and the other end of each rotating shaft 801 is connected to one of the rotating forks 802.

[0034] Furthermore, the wire storage drum 9 has a wire storage drum support shaft 901 and a wire winding drum 902 ; one wire storage drum support shaft 901 is movably connected to one of the rotating forks 802 , and each of the wire winding drums 902 is connected to one of the wire storage drum support shafts 901 .

[0035] Furthermore, the cross wire pulling frame 10 has a wire pulling shaft 1001, a cross frame 1002 and a wire pulling channel 1003; the wire pulling shaft 1001 is connected to the transmission shaft 302, the cross frame 1002 is arranged at one end of the wire pulling shaft 1001, and the four wire pulling channels 1003 are respectively arranged at the four ends of the cross frame 1002; the core traction part 4 is passed through the wire pulling shaft 1001.

[0036] Furthermore, the roller assembly 11 includes a roller 1101 and a roller shaft 1102. The two rollers 1101 are connected to each other, and each roller 1101 is connected to a corresponding roller shaft 1102. The insulation layer or the insulation layer with the completed shielding layer can pass through between the two connected rollers 1101 to prevent the insulation layer and the wire core from curling up or other undesirable problems.

[0037] Specifically, when the drive motor 101 is powered on, it can drive the drive shaft 102 to rotate, and then transmit the driving force to the output power shaft 201 through the coupling 103. When the output power shaft 201 is driven to rotate, it can simultaneously drive the first output gear 202 and the second output gear 203, which have different numbers of teeth and other specifications, to rotate simultaneously. When the first output gear 202 is driven, the first transmission gear 301 can be driven by meshing transmission, and then the first transmission gear 301 drives the transmission shaft 302; and when the transmission shaft 302 rotates, it can simultaneously drive the central connecting sleeve 501 and the wire pulling shaft 1001, so that the swing arm 502 drives the rotating fork 802 and the wire storage drum 9, so that each of the wire storage drums 9 can revolve along a predetermined circular trajectory; and when the wire pulling shaft 1001 rotates, it can drive the cross frame 1002 to rotate, so that the wire pulling channel 1003 at each end of the cross frame 1002 also rotates at the same time. At this time, the metal wire pulled out from the winding drum 902 and passing through each of the traction channels 1003 can be woven outside the insulation layer before the roller group 11.

[0038] Furthermore, when the second output gear 203 is driven, it can drive the second transmission gear 602 through meshing transmission, and the second transmission gear 602 can rotate by driving the central gear sleeve 601 so that it is sleeved outside the transmission shaft 302. At this time, since the first output gear 202 and the first transmission gear 301, and the second output gear 203 and the second transmission gear 602 have different transmission ratios, when the central gear sleeve 601 rotates, it has different rotation parameters with the transmission shaft 302. When the central gear sleeve 601 rotates, it can drive the central gear 603, and the central gear 603 can simultaneously drive each of the planetary gears 7 through meshing transmission, so that the rotation shaft 801 connected to each of the planetary gears 7 can be driven to rotate. At this time, the rotating fork 802 drives the winding reel 902 to achieve self-rotation.
