Detailed Implementation

[0032] The technical solutions of the embodiments 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, and 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.

[0033] Please see Figures 1-6This invention provides a copper wire constant tension regulating cable stranding device, including a base 1, a stranding mechanism disposed on the base 1, the stranding mechanism conveying copper wire through a first mounting plate 3 and a second mounting plate 4 thereon; an adjusting mechanism disposed on the second mounting plate 4, the adjusting mechanism limiting and adjusting the copper wire through a first pulley 402, a second pulley 412 and a third pulley 415 therein; and a support mechanism disposed on the top of the base 1, the support mechanism supporting the second mounting plate 4 through a support seat 101 and a roller 107 therein; and an adjusting mechanism. The mechanism includes a first motor 406 controlling the second pulley 412 to move up and down, facilitating the adjustment of the copper wire tension. A second motor 413 controls the rotating plate 414 to rotate, which in turn drives the third pulley 415 to move up and down along an arc-shaped trajectory, also adjusting the copper wire tension. By setting up the mechanism so that if one of the pulleys 412 or 415 gets stuck, the other pulley can be activated to adjust and guide the copper wire. In the event of a jam, emergency measures can be taken to allow the copper wire to continue feeding until the stranding is complete, thus minimizing the impact on the cable stranding process.

[0034] In some embodiments, see Figure 2 , Figure 4The adjustment mechanism includes a mounting plate 401, a first pulley 402, a moving groove 404, a first mounting port 405, a first motor 406, a lead screw 407, a second mounting port 408, a limiting post 409, a moving plate 410, a second pulley 412, a second motor 413, a rotating plate 414, and two third pulleys 415. The outer wall of the second mounting plate 4 has several slots. The mounting plate 401 is fixedly installed in the slots by screws. The first pulley 402 is located on one side of the mounting plate 401. The moving groove 404, the first mounting port 405, and the second mounting port 408 are located on one side of the mounting plate 401, respectively on both sides of the moving groove 404. The first motor 406 is fixedly installed at the bottom of the inner wall of the first mounting port 405. The lead screw 407 is fixedly installed at the output end of the first motor 406. The limiting post 409 is fixedly installed on the inner wall of the second mounting port 408. The two sides of the movable plate 410 are slidably installed on the inner walls of the corresponding first mounting port 405 and second mounting port 408, respectively. One side of the movable plate 410 is threaded to the outer wall of the lead screw 407 through its internal threaded hole, and the other side of the movable plate 410 is slidably installed on the outer wall of the limiting post 409 through its hole. The second pulley 412 is set on the top of the movable plate 410, and the second motor 413 is fixedly installed on one side of the movable plate 410. The output end of the second motor 413 extends into the interior of the movable plate 410, and the rotating plate 414 is fixedly installed on the output end of the second motor 413. Two third pulleys 415 are rotatably installed on the inner wall of the corresponding rotating plate 414. The copper wire passes through the bottom of the first pulley 402 and the top of the second pulley 412. When the second pulley 412 rises, it can increase the tension of the copper wire. When the second pulley 412 falls, it can reduce the tension of the copper wire. The adjustment of the copper wire tension by the third pulley 415 is consistent with that of the second pulley 412.

[0035] In this example, the first motor 406 and the second motor 413 can be servo motors. The first motor 406 starts and drives the lead screw 407 to rotate. The lead screw 407 is connected to the moving plate 410 by a thread, which drives the moving plate 410 to move up and down. The moving plate 410 is limited by the limit post 409 when it moves up and down. The second motor 413 starts and drives the rotating plate 414 to rotate, thereby driving the third pulley 415 to move.

[0036] In this example, the first pulley 402 is installed via a fixing plate 403, and the second pulley 412 is installed via a mounting bracket 411, which facilitates the disassembly and replacement of the first pulley 402 and the second pulley 412.

[0037] In some embodiments, see Figure 5The first pulley 402 has fixed plates 403 rotatably mounted at both ends, and the fixed plates 403 are fixed to one side of the mounting plate 401 by screws. The top of the movable plate 410 is fixed to the mounting bracket 411 by screws. The third pulley 415 is rotatably mounted on the top of the inner wall of the mounting bracket 411. The top of the wall of the movable groove 404 has ventilation holes 5, and the top of the inner wall of the ventilation holes 5 is fixedly mounted with a filter screen 501. The wall of the movable groove 404 is fixedly mounted with an air pump 502, and the wall of the movable groove 404 is fixedly mounted with a connecting plate 503. Several nozzles 504 are fixedly installed at the bottom of the connecting plate 503. One end of the air pump 502 outlet is connected to the nozzles 504 through a pipe. The filter screen 501 can be a cotton filter element. The filter screen 501 is used to filter the air. When the air pump 502 is started, the air is delivered to the nozzles 504 and sprayed out. The nozzles 504 are respectively facing the first pulley 402 and the second pulley 412, which can blow away the dust on the first pulley 402 and the second pulley 412 and reduce the adhesion of dust on the first pulley 402 and the second pulley 412.

[0038] In some embodiments, see Figure 2 The stranding mechanism includes a mounting base 2, a drive motor 201, a first mounting plate 3, several pay-off reels 301, several connecting brackets 302, and a second mounting plate 4. The mounting base 2 is fixedly mounted on the top of the base 1. The drive motor 201 is fixedly mounted on the top of the mounting base 2. A mounting shaft is fixedly mounted on the output end of the drive motor 201. The first mounting plate 3 is fixedly mounted on one end of the mounting shaft. Several fixing holes are opened on the outer wall of the first mounting plate 3. The pay-off reels 301 are fixedly mounted on the inner wall of the fixing holes by screws. Several connecting brackets 302 are fixedly mounted on the first mounting plate. At one end of the first mounting plate 3, the second mounting plate 4 is fixedly installed on one end of the connecting frame 302. A bracket 202 is fixedly installed on the top of the base 1, and a slip ring 203 is fixedly installed on the top of the bracket 202. The slip ring 203 is located on the outer ring of the mounting shaft, and one end of the slip ring 203 is fixedly installed on one end of the second mounting plate 4. The drive motor 201 is used to drive the first mounting plate 3 and the second mounting plate 4 to rotate. A mounting cylinder is installed on the wire feeding reel 301, and a coiled copper wire is installed on the mounting cylinder. A servo motor is provided on the side of the wire feeding reel 301, which can control the rotation of the mounting cylinder and control the wire feeding.

[0039] In this example, the slip ring 203 is existing technology. The first motor 406, the second motor 413 and the air pump 502 are connected to one end of the slip ring 203 mounted on the first mounting plate 3 by wires. The slip ring 203 is configured to supply power to the first motor 406, the second motor 413 and the air pump 502 when the first mounting plate 3 and the second mounting plate 4 rotate.

[0040] In this example, a traction mechanism for cable stranding, which is common in the prior art, is provided on one side of the base 1. After the first mounting plate 3 and the second mounting plate 4 rotate to strand the copper wires together, the stranded copper wires are transported by the traction mechanism. The traction mechanism in the prior art is usually composed of one or more pairs of rubber wheel traction wheels, which are driven by a motor to roll and clamp the stranded cable and pull it forward. The traction speed must be matched with the stranding speed to ensure that the stranding pitch is stable. If the traction is too fast, the stranding will be too loose; if it is too slow, it will lead to over-stretching.

[0041] In some embodiments, see Figure 6 The support mechanism includes several support seats 101 and several rollers 107. The support seats 101 are fixedly installed on both sides of the top of the base 1, and the rollers 107 are rotatably installed on one side of the support seats 101. By setting the support seats 101 to support both sides of the bottom of the second mounting plate 4, the second mounting plate 4 rotates more stably.

[0042] For further details, please refer to the following: Figure 6 The support base 101 is located on both sides of the outer wall of the second mounting plate 4. The roller 107 is located between the outer wall of the second mounting plate 4 and one side of the support base 101. A mounting groove 102 is provided on one side of the support base 101. A fixing groove 104 is provided at the top of the groove wall of the mounting groove 102. A water tank 103 is installed on the groove wall of the mounting groove 102. A pump body 105 is fixedly installed on the groove wall of the fixing groove 104. A hose is fixedly installed at one end of the inlet of the pump body 105. One end of the hose extends to the bottom of the water tank 103. Several conveying channels 106 are provided on one side of the fixing groove 104. The other end of the conveying channel 106 extends to the position of the roller 107 on one side of the support base 101. One end of the pump body 105 outlet is connected to the corresponding conveying channel 106 through a pipe. The water tank 103 is filled with lubricating oil and is inserted into the mounting groove 102 on the support base 101. The pump body 105 delivers the lubricating oil in the water tank 103 to the surface of the roller 107. When the roller 107 rotates, it applies the lubricating oil to the outer wall of the second mounting plate 4, which can make the second mounting plate 4 rotate more smoothly on the support base 101.

[0043] The working process and principle of the present invention are as follows: When the copper wire is stranded, a servo motor is provided on the side of the wire feeding reel 301, which can control the rotation of the mounting cylinder and control the wire feeding. The drive motor 201 is used to drive the first mounting plate 3 and the second mounting plate 4 to rotate, so that the copper wire is stranded together. A traction mechanism for cable stranding in the prior art is provided on one side of the base 1. After the first mounting plate 3 and the second mounting plate 4 rotate to strand the copper wire together, the stranded copper wire is transported by the traction mechanism.
