[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] In one embodiment, such as Figures 1-7As shown, a shielded cable braiding machine with uniform braiding density includes a support frame 100. A fixed plate 101 is fixedly connected to the support frame 100. A limiting plate 103 is fixedly connected to the upper end of the fixed plate 101 via a first fixing post 102. The limiting plate 103 is provided with a first annular track 104 and a second annular track 105. The first annular track 104 and the second annular track 105 intersect each other and divide the limiting plate 103 into eight connecting plates 106. The eight connecting plates 106 are fixedly connected to the fixed plate 101 via a second fixing post 107. Eight limiting blocks 108 are slidably connected in the first annular track 104 and the second annular track 105, respectively. The disc 101 is equipped with a transmission component that drives the movement of the limiting block 108. The limiting block 108 is equipped with a feeding mechanism, and the support frame 100 is equipped with a winding module. The shielding wire is pulled out from the feeding mechanism on the limiting block 108. The transmission component drives the limiting block 108 to move. The limiting blocks 108, located in the first annular track 104 and the second annular track 105 respectively, slide along the first annular track 104 and the second annular track 105 respectively. Since the first annular track 104 and the second annular track 105 intersect each other, the limiting blocks 108 cause the shielding wires to intersect each other during the movement, thereby braiding the cable. The braided cable is then wound up and organized by the winding module.
[0028] In this embodiment, as Figures 3-5As shown, the transmission component includes eight rotating sleeves 201, which are rotatably connected to the outer ends of fixed posts 107. Gear 202 and rotating disk 203 are fixedly connected to the outer ends of the eight rotating sleeves 201. The eight gears 202 mesh with each other, and the eight rotating disks 203 are tangent to each other in pairs. Four limiting grooves 204 are evenly provided on the eight rotating disks 203. A motor 205 is fixedly connected to the fixed disk 101. The output shaft of the motor 205 is fixedly connected to a gear 206, which meshes with one of the gears 202. Limiting rods 207 are fixedly connected to the lower ends of the eight limiting blocks 108. The limiting rods 207 engage with the limiting grooves 204. When the motor 205 is started, it drives the gear 206 to rotate. The gear 206 drives the gear 1 202 to rotate, which in turn drives the rotating sleeve 201 to rotate. The rotating sleeve 201 drives the rotating disk 203 to rotate, which in turn drives the limiting rod 207 located in the limiting groove 204 to rotate. The limiting rod 207 drives the limiting block 108 to move. Since the limiting block 108 is slidably connected in the first annular track 104 and the second annular track 105 respectively, when the limiting rod 207 rotates with the rotating disk 203 to the adjacent rotating disk 203, the limiting block 108 causes the limiting rod 207 to be engaged in the limiting groove 204 of the adjacent rotating disk 203 and rotate with the adjacent rotating disk 203. The above operation is repeated, so that the limiting block 108 slides along the first annular track 104 and the second annular track 105 respectively, completing the weaving of the shielding wire.
[0029] In one embodiment, such as Figure 6As shown, the feeding mechanism includes a fixed block 301, which is fixedly connected to the upper end of the limiting block 108. A feeding frame 302 is fixedly connected to the upper end of the fixed block 301. A feeding roller 303 is rotatably connected to the feeding frame 302. Two limiting plates 304 are fixedly connected to the feeding frame 302. Grooves are provided on the two limiting plates 304. Sliding rods 305 are fixedly connected to the grooves of the limiting plates 304. The outer ends of the two sliding rods 305 are slidably connected to a first sliding block 306. A threading ring 307 is fixedly connected to the first sliding block 306. A spring 308 is provided at the outer end of each sliding rod 305. One end of the spring 308 is fixedly connected to the first sliding block 306. The other end of 308 is fixedly connected to the limiting plate 304. The upper end of the wire feeding frame 302 is provided with a second wire threading ring 309. The wire feeding frame 302 is provided with a wire threading hole 310 in the middle. The shielding wire is placed on the wire feeding roller 303. The shielding wire is passed through the wire threading hole 310, the first wire threading ring 307 and the second wire threading ring 309 in sequence for weaving. During the weaving process, if the tension of the shielding wire is too large, it will drive the first wire threading ring 307 to move upward. The first wire threading ring 307 drives the first sliding block 306 to move upward along the sliding rod 305 and compress the spring 308. When the tension decreases, the first wire threading ring 307 returns to its original position under the action of the spring 308, preventing the shielding wire from breaking due to excessive tension during the weaving process and ensuring the normal operation of the device.
[0030] In one embodiment, such as Figure 7 As shown, the winding module includes two fixed plates 401, which are fixedly connected to the support frame 100. A winding frame 402 is fixedly connected to the two fixed plates 401, and a winding roller 403 is rotatably connected to the winding frame 402. One end of the winding roller 403 is coaxially fixedly connected to pulley 404 and pulley 405. Pulley 404 is connected to pulley 406 via a belt, and pulley 406 is fixedly connected to the output shaft of motor 407. The second motor 407 is fixedly connected to the winding frame 402. The second pulley 405 is connected to the lead wire module. When the second motor 407 is started, the second motor 407 drives the third pulley 406 to rotate. The third pulley 406 drives the first pulley 404 to rotate through the belt. The first pulley 404 drives the winding roller 403 to rotate. The winding roller 403 rotates to wind up the braided cable. The lead wire module assists the winding roller 403 to make the cable evenly wound on the winding roller 403, thus improving the cable winding effect.
[0031] In one embodiment, such as Figure 7As shown, the lead-in module includes a connecting rod 501, which is fixedly connected to the take-up frame 402. The connecting rod 501 has a sliding groove, in which a reciprocating lead screw 502 is rotatably connected. One end of the reciprocating lead screw 502 is fixedly connected to a pulley four 503, which is connected to a pulley two 405 via a belt. The outer end of the reciprocating lead screw 502 is threadedly connected to a second sliding block 504, which is fixedly connected to a threading ring three 505. When the take-up roller 403 is winding, it drives the pulley two 405 to rotate, which in turn drives the pulley four 503 to rotate. The pulley four 503 drives the reciprocating lead screw 502 to rotate, which in turn drives the second sliding block 504 to move left and right. The second sliding block 504 then drives the threading ring three 505 to move left and right, causing the cable to be neatly wound onto the take-up roller 403.
[0032] In one embodiment, such as Figure 1 As shown, the cable outlet tube 600 is fixedly connected in the middle of the limiting plate 103, and the cable that has not yet been braided is passed through the cable outlet tube 600 to facilitate braiding.
[0033] In one embodiment, such as Figure 1 As shown, a support rod 701 is fixedly connected between the two fixed plates 401, and a conduit 702 is fixedly connected in the middle of the support rod 701 to guide the braided cable and facilitate winding.
[0034] In one embodiment, such as Figure 3 As shown, the eight limiting blocks 108 respectively set in the first annular track 104 and the second annular track 105 are distributed at intervals. When the limiting blocks 108 move in the first annular track 104 and the second annular track 105, they drive the shielding wires to cross and weave together, so that the braided wires are evenly woven.
[0035] The above embodiment discloses a shielded cable braiding machine with uniform braiding density. The shielding wire roll is placed on the unwinding roller 303, and the shielding wire is sequentially passed through the threading hole 310, threading ring one 307, and threading ring two 309 for braiding. Motor one 205 is started, which drives gear two 206 to rotate. Gear two 206 drives gear one 202 to rotate, gear one 202 drives rotating sleeve 201 to rotate, rotating sleeve 201 drives rotating disk 203 to rotate, rotating disk 203 drives limiting rod 207 located in limiting groove 204 to rotate, and limiting rod 207 drives limiting block 108. The movement is facilitated by the slidable connection of the limiting blocks 108 to the first annular track 104 and the second annular track 105. When the limiting rod 207 rotates with the rotating disk 203 to the adjacent rotating disk 203, the limiting blocks 108 cause the limiting rod 207 to engage in the limiting groove 204 of the adjacent rotating disk 203, and it rotates with the adjacent rotating disk 203. This process is repeated, causing the limiting blocks 108 to slide along the first annular track 104 and the second annular track 105. Since the first annular track 104 and the second annular track 105 intersect each other, the limiting rod 207 is positioned on the annular track 105. During movement, the limiting blocks 108 in track 104 and the circular track 2 105 cause the shielding wires to cross each other, thus braiding the cable. During braiding, if the tension of the shielding wire is too high, it will cause the threading ring 307 to move upwards. The threading ring 307 then causes the first sliding block 306 to move upwards along the sliding rod 305, compressing the spring 308. When the tension decreases, the threading ring 307 returns to its original position under the action of the spring 308, preventing the shielding wire from breaking due to excessive tension during braiding. The motor 2 407 is then started, driving the pulley 3 406 to rotate. The third pulley 406 drives the first pulley 404 to rotate via a belt. The first pulley 404 drives the take-up roller 403 to rotate. The take-up roller 403 rotates to wind up the braided cable. When the take-up roller 403 is winding, it drives the second pulley 405 to rotate. The second pulley 405 drives the fourth pulley 503 to rotate. The fourth pulley 503 drives the reciprocating screw 502 to rotate. The reciprocating screw 502 drives the second sliding block 504 to move left and right. The second sliding block 504 drives the third threading ring 505 to move left and right. The third threading ring 505 drives the cable to be neatly wound on the take-up roller 403, improving the cable winding effect.
