Description

Technical Field

[0001] The invention belongs to the field of cable production and processing, and in particular relates to a cable core twisting device. Background Art

[0002] Cable core twisting is a key process in cable manufacturing. It is done by twisting multiple single-strand cores into bundles at a specific pitch and direction to improve the flexibility, electrical performance and mechanical strength of the cable. During the twisting process, after the core is drawn out from the wire drum, it passes through the tensioning wheel and two twisting drums in sequence, and finally completes the twisting under the rotation of the two twisting drums. This process requires ensuring that the core tension is uniform and the twisted structure is tight to avoid performance degradation or early damage of the cable during use.

[0003] At present, there are significant problems in the operation of the wire core twisting device: due to equipment vibration, traction speed fluctuation or inaccurate tension control, the wire core will shake when passing through the guide hole on the twisting drum. This shaking will cause repeated collision and friction between the wire core and the inner wall of the guide hole. Long-term friction will damage the surface coating of the wire core and even cause wire breakage; and the collision impact may cause local deformation of the wire core, affecting the roundness after twisting, which will affect the quality of the wire core after twisting.

[0032] The following is combined with Figure 1 - Fig.11 This application is further described in detail.

[0033] Please refer to Figure 1 and Figure 2A cable core twisting device comprises a support frame 1, a support seat 1 2 and a support seat 2 3 are fixedly arranged on the front and rear sides of the upper part of the support frame 1, a rotating rod 4 is arranged between the support seat 1 2 and the support seat 2 3, a wire opening 5 is opened on the rotating rod 4, a wire-releasing component 6 for releasing the wire core is arranged at the outer rear end of the rotating rod 4, and a twisting component 7 for twisting the wire core is arranged between the rotating rod 4 and the support seat 2 3.

[0034] See also Figure 2 and Figure 5 The twisting assembly 7 includes a twisting drum 1 71 and a twisting drum 2 72 fixedly arranged on the outside of the rotating rod 4. The size of the twisting drum 1 71 is larger than that of the twisting drum 2 72. Both the twisting drum 1 71 and the twisting drum 2 72 are provided with a plurality of wire holes 73 distributed in a circular array for the wire core of the wire-releasing assembly 6 to pass through.

[0035] See also Figure 2 , Figure 3 and Figure 4 The pay-off assembly 6 includes a fixed disk 61 fixedly arranged at the rear end of the outer side of the rotating rod 4, a plurality of support rods 62 distributed in a circular array are fixedly arranged on the front side of the fixed disk 61, a pay-off disk 63 is rotatably arranged on the outer side of the support rod 62, a guide disk 64 is fixedly arranged on the outer side of the rotating rod 4 and located in front of the fixed disk 61, and a plurality of tensioning wheels 65 are rotatably arranged on the outer side of the guide disk 64.

[0036] See also Figure 1 and Figure 2 A wire gathering component 11 for pressing the twisted wire core is arranged on the front side of the support frame 1. The wire gathering component 11 includes an inverted U-shaped mounting plate 111 fixedly arranged on the front side of the support frame 1. A wire gathering seat 112 is fixedly arranged on the upper part of the mounting plate 111. A sizing opening 113 is opened on the wire gathering seat 112, and the sizing opening 113 and the wire opening 5 are on the same horizontal axis.

[0037] During the specific work, when the wire core is twisted, first a wire core is passed through the wire opening 5 on the rotating rod 4. This wire core will serve as the central wire core of the entire twisting process. Then the wire core on the pay-off reel 63 is passed through the wire holes 73 on the tensioning wheel 65, the twisting reel 1 71 and the twisting reel 2 72 in turn. Since the wire holes 73 on the twisting reel 1 71 and the twisting reel 2 72 are distributed in a circular array, after the wire core passes through these wire holes 73, it will be evenly distributed around the central wire core. Then all the wire cores pass through the sizing opening 113 together and are wound around the external take-up roller to facilitate subsequent twisting work.

[0038] See also Figure 1 and Figure 2A driving assembly 10 for driving the rotating rod 4 to rotate is arranged on the rear side of the support frame 1. The driving assembly 10 includes a motor 101 fixedly arranged on the rear side of the support frame 1. The output shaft of the motor 101 and the rotating rod 4 are connected to each other through a pulley assembly 102.

[0039] See also Figure 2 , Figure 3 and Figure 5 The capstan drum 1 71 includes two discs 1 711 that fit each other, and the capstan drum 2 72 includes two discs 2 721 that fit each other. The disc 1 711 located at the rear side and the disc 2 721 located at the rear side are both fixedly connected to the rotating rod 4. The front sides of the disc 1 711 located at the rear side and the disc 2 721 located at the rear side are fixedly provided with a plurality of positioning rods 74. The disc 1 711 located at the front side and the disc 2 721 located at the front side are both provided with a plurality of positioning openings 75 used in conjunction with the positioning rods 74. One end of the positioning rod 74 passes through the positioning opening 75 and a bolt is provided with an outer thread. A circular opening 12 is provided on the support seat 2 3. The front end of the rotating rod 4 is located in the circular opening 12. The rear end of the rotating rod 4 passes through the support seat 1 2 and is rotatably connected to the support seat 1 2. The two discs 2 721 are both located in the circular opening 12, and the disc 2 721 located at the rear side is rotatably connected to the circular opening 12.

[0040] See also Figure 1 and Figure 4 A connecting plate 66 is slidably provided on the outer side of the support rod 62 and located in front of the wire-releasing drum 63, and the connecting plate 66 is connected to the disc 711 located at the rear side by bolts.

[0041] During specific operation, after the wire core is wound around the external wire-receiving roller, the motor 101 starts to work. The motor 101 can drive the rotating rod 4 to rotate through the pulley assembly 102. The rotation of the rotating rod 4 can drive the fixed disk 61, the wire-paying disk 63, the twisting disk 1 71 and the twisting disk 2 72 to rotate synchronously. As the twisting disk 1 71 and the twisting disk 2 72 rotate, the wire core passing through the wire hole 73 will be twisted around the center wire core, so that the wire core on the wire-paying disk 63 can be twisted on the outside of the center wire core, thereby facilitating the twisting of the wire core, and the cooperation of the bolts and the mounting plate 111 facilitates the removal and replacement of the wire-paying disk 63.

[0042] See also Figure 3 , Figure 5 , Fig. 9 and Fig.10A protective component 8 is provided in the wire hole 73 to prevent the wire core from rubbing against the wire hole 73 when it shakes. The protective component 8 includes a rotating ring 81 rotatably arranged in the wire opening 5 on the rear disk 1 711 and the rear disk 2 721. A semicircular ring 1 82 and a semicircular ring 2 83 are provided on the front side of the rotating ring 81. Air bags 84 are fixedly provided on the inner sides of the semicircular ring 1 82 and the semicircular ring 2 83, and the two air bags 84 are tightly attached to each other on one side thereof. A pressure sensor 85 is fixedly provided inside the air bag 84.

[0043] See also Fig. 9 and Fig.10 Two arc grooves 86 are provided on one side of the rotating ring 81 close to the airbag 84, and an arc block 87 connected to the arc groove 86 is fixedly provided on one side of the airbag 84 close to the rotating ring 81. Sockets 88 are provided at both ends of the semicircular ring 1 82 close to the semicircular ring 2 83, and plug blocks 89 connected to the sockets 88 are fixedly provided at both ends of the semicircular ring 2 83 close to the semicircular ring 1 82.

[0044] In order to prevent the wire core from being damaged or broken due to friction with the wire opening 5 when twisted, after the wire core passes through the wire opening 5, the wire core is located between the corresponding two air bags 84, so that the wire core will contact the air bags 84 when shaking. The air bags 84 can effectively buffer the shaking of the wire core and prevent the wire core from being damaged or broken due to friction.

[0045] At the same time, through the cooperation of the arc block 87 and the rotating ring 81, the airbag 84 will also rotate accordingly with the shaking of the wire core. This rotation helps to disperse the friction between the wire core and the airbag 84, so that each part of the airbag 84 is evenly stressed, and the service life of the airbag 84 is extended. In the whole process, the pressure sensor 85 continuously monitors the pressure changes in the airbag 84. Once the airbag 84 leaks, the pressure in the airbag 84 will drop rapidly. At this time, the motor 101 stops working and the twisting work of the wire core is suspended to avoid damage to the wire core due to failure of the airbag 84. Then the staff can immediately replace the damaged airbag 84.

[0046] See also Figure 3 , Figure 6 , Figure 7 and Fig.11, the interior of the capstan drum 1 71 and the capstan drum 2 72 are both provided with multiple groups of limiting components 9 for limiting the protection component 8, a groove is provided on the front side of the disc 1 711, and the limiting component 9 includes a guide rod 91 fixedly arranged in the groove, a guide block 92 is slidably arranged on the guide rod 91, a return spring 1 93 is sleeved on the outer side of the guide rod 91, and the two ends of the return spring 1 93 are respectively connected to the inner wall of the groove and the guide block 92, one end of the guide block 92 passes through the groove and is fixedly provided with a wedge block 1 94, a sliding groove is provided on the side of the wedge block 1 94 close to the guide block 92, a return spring 2 95 is fixedly arranged inside the sliding groove, and a limit block 96 is fixedly arranged on the end of the return spring 2 95 away from the inner wall of the sliding groove, and the bottom end of the limit block 96 passes through the sliding groove.

[0047] See also Fig.11 A ball groove is provided on one side of the limit block 96 close to the semicircular ring 1 82 and the semicircular ring 2 83 , and a ball 961 is rolled in the ball groove, and the ball 961 is in rolling contact with one side of the circular ring 1 and the semicircular ring 2 83 .

[0048] In order to ensure that the airbag 84 will not move out of the wire opening 5 during use, during the twisting process, the airbag 84 will rotate with the shaking of the wire core and the rotation of the rotating ring 81, thereby driving the semicircular ring 1 82 and the semicircular ring 2 83 to rotate synchronously. In this continuous dynamic process, the limit block 96 always maintains contact with the semicircular ring 1 82 or the semicircular ring 2 83, which can not only limit the semicircular ring 1 82 and the semicircular ring 2 83 so that the airbag 84 will not move out of the wire opening 5 during use, but also the ball 961 will not easily affect the normal rotation of the semicircular ring 1 82 and the semicircular ring 2 83.

[0049] See also Figure 5 and Fig.11 A push rod 97 is fixedly provided on one side of the limit block 96 away from the guide block 92, and a plurality of sliding openings for the push rod 97 to move are provided on the front disc 1 711 and the front disc 2 721.

[0050] See also Figure 7 and Figure 8 The rear sides of the disc 1 711 located at the front side and the disc 2 721 located at the front side are both provided with a wedge block 2 13 used in conjunction with the wedge block 1 94, and the wedge block 2 13 abuts against the side of the wedge block 1 94 that is close to each other.

[0051] In order to facilitate the replacement of the damaged airbag 84, when the airbag 84 is damaged during the twisting process of the wire core, the twisting work is stopped at this time, and the staff can push the corresponding push rod 97 to drive the corresponding limit block 96 to move. After the limit block 96 moves, it moves away from the corresponding semicircular ring 1 82 and semicircular ring 2 83, thereby canceling the limit on the semicircular ring 1 82 and semicircular ring 2 83. At this time, the staff can directly move the semicircular ring 1 82 and semicircular ring 2 83 out of the wire hole 73, and then use the cooperation of the plug block 89 and the socket 88 to separate the semicircular ring 1 82 and semicircular ring 2 83, thereby avoiding the interference of the wire core on the disassembly operation.

[0052] When the twisting work is completed and the entire airbag 84 needs to be maintained or cleaned, the staff can remove the bolts on the positioning rod 74, and then disassemble the disc 1 711 and the disc 2 721 on the front side. When the disc 1 711 and the disc 2 721 on the front side move, they will drive the wedge block 2 13 to move away from the wedge block 1 94. At this time, the squeezing force on the wedge block 1 94 disappears, and then the reset spring 1 93 can be used to drive the wedge block 1 94 to move. The movement of the wedge block 1 94 drives the limit block 96 to move in the direction away from the semicircular ring 1 82 and the semicircular ring 2 83, thereby eliminating the limit on the semicircular ring 1 82 and the semicircular ring 2 83, making it convenient to take out the airbags 84 in all the wire holes 73 for maintenance or cleaning.

[0053] During specific operation, the driving component 10 can be used to drive the rotating rod 4 to rotate, and then the wire core can be twisted by the cooperation of the pay-off component 6 and the twisting component 7. In the process of twisting, the airbag 84 can effectively buffer the shaking of the wire core during the twisting process to prevent the wire core from being damaged or broken due to friction; at the same time, through the cooperation of the arc block 87 and the rotating ring 81, the airbag 84 will also rotate accordingly with the shaking of the wire core. This rotation helps to disperse the friction between the wire core and the airbag 84, so that each part of the airbag 84 is evenly stressed, thereby extending the service life of the airbag 84.

[0054] Furthermore, when the airbag 84 is damaged and needs to be replaced, the corresponding push rod 97 is pushed to drive the corresponding limit block 96 to move, thereby canceling the limit on the semicircular ring 1 82 and the semicircular ring 2 83, and then the semicircular ring 1 82 and the semicircular ring 2 83 can be separated conveniently by utilizing the cooperation of the plug block 89 and the socket 88, and the interference of the wire core with the disassembly operation can be avoided.

[0055] When the twisting work is completed and the entire airbag 84 needs to be maintained or cleaned, the staff can disassemble the disc 1 711 and the disc 2 721 located on the front side, and then use the cooperation of the wedge block 1 94 and the wedge block 2 13 to facilitate the removal of the airbag 84 in all the wire holes 73 for maintenance or cleaning.
