Description
Technical Field
[0001] This utility model relates to the field of cable pre-twisting technology, specifically to a cable pre-twisting device to prevent breakage. Background Technology
[0002] A pre-twisting machine is a mechanical device that twists various soft / hard conductor wires and electronic wires together. When the pre-twisting machine is working, the cable is driven by the drive shaft. If the speed is too high, the cable may be twisted and broken, which will not only cause the cable to be scrapped, but also damage the pre-twisting machine to a certain extent.
[0003] For example, Chinese utility model patent CN220208633U discloses a pre-twisting device for a wire harness machine, including a rotating strand, with a wire-passing hole axially formed inside the rotating strand, and a roller mounting groove connected to the wire-passing hole. The rotation direction of the rotating strand is opposite to the rotation direction of the wire harness machine; a roller assembly installed in the roller mounting groove, with two sets of roller mounting grooves; a support mechanism, with both ends of the rotating strand rotatably connected to the support mechanism; and a synchronous pulley located at one end of the rotating strand.
[0004] In the aforementioned pre-twisting device for a wire harness machine, the cable enters through a threading hole, passes through a roller assembly, and then exits through a threading hole at the other end. Since the cable drives the rolling assembly to roll, the cable is easily broken when the rotation speed of the twisting body is too high. Utility Model Content

[0013] The beneficial effects of this utility model are:
[0014] This utility model provides a cable pre-twisting device to prevent twisting and breakage, comprising a frame and a rotating body. The frame includes a base plate and a first leg and a second leg perpendicular to the base plate and arranged opposite to each other.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0023] This embodiment provides a cable pre-twisting device to prevent breakage, such as... Figures 1 to 4 As shown, the device includes a housing 1 and a rotating hinge 2, wherein the housing 1 encloses the rotating hinge 2 within the housing 1. A first sliding door 101 and a second sliding door 102 are provided on the housing 1, and the first sliding door 101 and the second sliding door 102 are mirror images of each other. The first sliding door 101 and the second sliding door 102 can be opened away from each other or closed close together. A slide rail 103 is also provided on the top of the housing 1, and the first sliding door 101 and the second sliding door 102 slide along the slide rail 103 to open or close. A first handle 104 for sliding the first sliding door 101 is also provided, and a second handle 105 for sliding the second sliding door 102 is also provided.
[0024] Furthermore, the rotating auger 2 includes a frame 201, which includes a base plate 211, a first leg 221, and a second leg 241. The first leg 221 and the second leg 241 are vertically arranged on the base plate 211 and are arranged opposite to each other.
[0025] The rotating auger 2 also includes a rotating body 202, which is rotatably connected to the frame 201. Specifically, one end of the rotating body 202 is rotatably connected to the top of the first leg 221, and the other end of the rotating body 202 is rotatably connected to the top of the second leg 241. A first drive motor 261 is also provided on the base plate 211, which drives the rotating body 202 to rotate via a belt.
[0026] A first bearing seat 231 is provided on the top of the first leg 221, and a second bearing seat 251 is provided on the top of the second leg 241. The first bearing seat 231 is used to install one end of the rotating body 202, and the second bearing seat 251 is used to install the other end of the rotating body 202. By setting the first bearing seat 231 and the second bearing seat 251, the first drive motor 261 is prevented from shaking when driving the rotating body 202 to rotate.
[0027] Furthermore, the rotating body 202 has a coaxially arranged inlet 212 and outlet 222 at both ends. The inlet 212 penetrates the left side wall of the housing 1, and the outlet 222 penetrates the right side wall of the housing 1. The rotating body 202 is also provided with a mounting groove 232. The inlet 212, the mounting groove 232 and the outlet 222 are connected in sequence. The mounting groove 232 is provided with a winding wheel 242 and a cable guide wheel 262. Below the winding wheel 242, there is a second drive motor 252 for driving the winding wheel 242 to rotate. The mounting groove 232 is also provided with a first corner roller group 272 and a second corner roller group 282. The first corner roller group 272 is located near the inlet 212, and the second corner roller group 282 is located near the outlet 222. In use, the cable enters through the inlet 212, passes through the first corner roller group 272, the winding wheel 242, the cable guide wheel 262, and the second corner roller group 282 in sequence, and then exits through the outlet 222. Then, the first drive motor 261 is started, causing the first drive motor 261 to drive the rotating body 202 to rotate. At the same time, the second drive motor 252 simultaneously drives the winding wheel 242 to rotate, and makes it rotate at the same speed as the rotating body 202. Since the second drive motor 252 simultaneously drives the winding wheel 242 to rotate and maintains the same speed as the rotating body 202, the tension on the cable is maintained, thereby avoiding the cable from breaking due to the excessive speed of the rotating body 202.
[0028] Furthermore, the rotating body 202 is equipped with a brake disc 292, which is located at one end near the second leg 241. A brake device 271 for clamping the brake disc 292 and stopping it is also provided on the top of the second leg 241. The brake device 271 includes a fixing plate 281, a gripper 291, and a controller 2911. The gripper 291 is fixed on the fixing plate 281, and the controller 2911 is connected to the gripper 291 and is used to control it to release or clamp the brake disc 292. A friction pad 2912 for braking the brake disc 292 is also provided on the gripper 291. By setting the brake device 271, after the cable pre-twisting is completed, the brake device 271 can stop the rotating body 202 in time to avoid excessive pre-twisting of the remaining cable and waste. At the same time, it can also prevent the rotating body 202 from failing to stop in time when the equipment malfunctions, which would cause damage to the equipment.
