[0032] Combine the following Figures 1 to 5 , describing a wire twisting tool for cables according to an embodiment of the utility model.

[0033] A wire twisting tool for a cable, comprising a frame 1, a moving assembly 2, a wire twisting assembly 3 and a driving assembly 4; the wire twisting assembly 3 comprises a wire twisting piece 31 and a wire twisting mounting frame 32, the wire twisting piece 31 is rotatably mounted on the wire twisting mounting frame 32, the frame 1 is mounted with a moving assembly 2, the moving assembly 2 is mounted with two wire twisting mounting frames 32, the wire twisting piece 31 is used to fix one end of the protective wire, the driving assembly 4 is used to drive the wire twisting piece 31 to rotate, the rotation of the wire twisting piece 31 drives the protective wire to wrap around the outer periphery of the cable, and the moving assembly 2 is used to drive the two wire twisting mounting frames 32 to move closer to or away from each other.

[0034] The present invention is a wire twisting tool for cables, wherein the wire twisting member 31 can fix the protective wire, and then the driving assembly 4 can drive the wire twisting member 31 to rotate on the wire twisting mounting frame 32, so that the protective wire is automatically wound around the outer periphery of the cable. At the same time, the moving assembly 2 can drive the wire twisting mounting frame 32 to move on the frame 1, so that the wire twisting member 31 can rotate continuously, ensuring that the end of the protective wire is also wound around the cable, solving the problem of low efficiency of the traditional manual wire twisting of the protective wire.

[0035] It is worth mentioning that the staff can adjust the moving speed of the moving component 2 to change the range of the cable wrapped by the protective wire.

[0036] The wire twisting assembly 3 also includes a wire twisting gear 33; the wire twisting piece 31 is provided with a plurality of through holes 311, and the through holes 311 are used for the wire protection line to pass through. The wire twisting gear 33 is fixedly installed on the side wall of the wire twisting piece 31, and the wire twisting piece 31 and the wire twisting gear 33 are both provided with a wire twisting notch 312, and the wire twisting notch 312 is used for the cable to pass through.

[0037] The wire twisting notch 312 can be passed through by the cable, so that the wire twisting member 31 can be hung on the cable. When the wire twisting member 31 rotates, the through hole 311 of the wire twisting member 31 also rotates, so that the protective wire can be wound around the cable under the action of the wire twisting member 31, thereby completing the wire twisting work.

[0038] The wire twisting mounting frame 32 is provided with a limiting groove 320 , and the wire twisting member 31 is rotatably connected to the limiting groove 320 .

[0039] The limiting groove 320 can play a limiting role and prevent the wire twisting member 31 from being separated from the wire twisting mounting frame 32 during the wire twisting process.

[0040] The wire twisting assembly 3 further includes a first transmission gear 34 and a second transmission gear 35. The first transmission gear 34 and the second transmission gear 35 are rotatably mounted on the wire twisting mounting frame 32, respectively. The first transmission gear 34 is meshed with the wire twisting gear 33, and the second transmission gear 35 is meshed with the wire twisting gear 33.

[0041] The first transmission gear 34 is coaxially mounted with a third transmission gear 36, the second transmission gear 35 is coaxially mounted with a fourth transmission gear 37, a belt 38 is sleeved on the outer sides of the third transmission gear 36 and the fourth transmission gear 37, and the driving end of the driving assembly 4 is used to drive the third transmission gear 36 and the first transmission gear 34 to rotate.

[0042] Since the first transmission gear 34 and the third transmission gear 36 are coaxially arranged, the driving end of the driving assembly 4 can simultaneously drive the third transmission gear 36 and the first transmission gear 34 to rotate. At this time, the third transmission gear 36 can drive the belt 38 to rotate, the belt 38 can drive the fourth transmission gear 37 to rotate, and the fourth transmission gear 37 can rotate the second transmission gear 35, so that the second transmission gear 35 can drive the twisting gear 33 to rotate. At the same time, the first transmission gear 34 also drives the twisting gear 33 to rotate.

[0043] It is worth mentioning that a wire twisting notch 312 is provided on the wire twisting gear 33. When the wire twisting notch 312 rotates to below the first transmission gear 34, the second transmission gear 35 can drive the wire twisting gear 33 to continue rotating. Similarly, when the wire twisting notch 312 rotates to below the second transmission gear 35, the first transmission gear 34 can drive the wire twisting gear 33 to continue rotating.

[0044] The driving assembly 4 includes a first power member 41, a first driving gear 42 and a second driving gear 43. The driving end of the first power member 41 is fixedly connected to the first driving gear 42. The first driving gear 42 is meshed with the second driving gear 43. The second driving gear 43 is coaxially arranged with the first transmission gear 34.

[0045] It should be noted that the first power member 41 is a motor. When the first power member 41 is started, it can drive the first driving gear 42 to rotate, and the rotation of the first driving gear 42 can drive the second driving gear 43 to rotate, and the rotation of the second driving gear 43 can drive the first transmission gear 34 and the third transmission gear 36 to rotate, thereby driving the twisting member 31 to rotate, so as to twist the wire of the protective wire.

[0046] The twisted wire mounting frame 32 is rotatably mounted with an adjusting roller 39 , and the adjusting roller 39 abuts against the belt 38 .

[0047] The adjusting roller 39 is constantly in contact with the belt 38 , and can slightly adjust the tension of the belt 38 , thereby preventing the belt 38 from being too loose and causing the belt 38 to fall off.

[0048] The moving assembly 2 includes a bidirectional screw rod 21, a second power member 22, a first moving gear 23 and a second moving gear 24; the bidirectional screw rod 21 is rotatably mounted below the frame 1, the end of the bidirectional screw rod 21 is fixedly sleeved with the first moving gear 23, the driving end of the second power member 22 is fixedly sleeved with the second moving gear 24, and the second moving gear 24 is meshed with the first moving gear 23;

[0049] Both ends of the bidirectional screw rod 21 are connected to the twisted wire mounting bracket 32 ​​.

[0050] It is worth noting that the second power member 22 is a motor. When the second power member 22 is started, it can drive the second moving gear 24 to rotate, and the second moving gear 24 can drive the first moving gear 23 to rotate. Since the first moving gear 23 and the bidirectional screw rod 21 are coaxially arranged, the first moving gear 23 can drive the bidirectional screw rod 21 to rotate, so that the twisted wire mounting frames 32 at both ends of the bidirectional screw rod 21 are close to each other or away from each other.

[0051] The two ends of the bidirectional screw rod 21 are movably sleeved with sliders 25, and the sliders 25 are fixedly connected to the twisted wire mounting frame 32;

[0052] A guide rail 26 is disposed on the bottom wall of the frame 1 , and the guide rail 26 is slidably connected to the slider 25 .

[0053] When the bidirectional screw 21 rotates, the slider 25 moves back and forth on the guide rail 26 driven by the bidirectional screw 21 . At this time, the guide rail 26 can limit the sliding direction and sliding range of the slider 25 , thereby limiting the slider 25 from starting to rotate under the action of the bidirectional screw 21 .

[0054] The opening of the twisted wire gap 312 spreads outward from the center of the twisted wire piece 31 , and the opening area of ​​the outer edge of the twisted wire gap 312 is less than 1 / 4 of the outer edge area of ​​the twisted wire piece 31 .

[0055] This solution limits the opening size of the wire twisting notch 312, which can ensure that when the wire twisting notch 312 moves to the bottom of the first transmission gear 35, the second transmission gear 35 engages with the wire twisting piece 31, thereby driving the wire twisting piece 31 to continue to rotate on the wire twisting mounting frame 32, thereby ensuring that the wire twisting piece 31 can rotate continuously under the action of the first transmission gear 35 or the second transmission gear 36, and then the protective wire is wrapped around the cable line.

[0056] A guide plate 313 is provided on one side of the wire twisting member 31 away from the wire twisting gear 33 . The guide plate 313 surrounds the through hole 311 and extends outward.

[0057] In order to prevent the protective wire from getting entangled with itself and forming a knot during the rotation of the wire twisting member 31, an outwardly extending guide plate 313 is provided on the wire twisting member 31. The guide plate 313 can guide and support the protective wire to prevent the protective wire from getting entangled with itself.

[0058] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
