Description

Technical Field

[0001] The utility model relates to the technical field of cable filling rope processing, in particular to an automatic twisting device for cable stranding filling ropes. Background Technique

[0002] If one end of the spinning is held and the other end rotates, a yarn can be formed, and this process is called twisting. Twisting is a process that uses rotational motion to twist the drawn sliver, like wringing a towel when washing the face, so as to fix the longitudinal connection between fibers. When the sliver twists once around its own axis, it is called adding one "twist". Twisting utilizes the bending and twisting of fibers. Bending can cause winding, and twisting will form twists. If one end of the fiber sliver is fixed and the other end is twisted with a certain tension, twists will be generated. If there is no tension, the twisting of the fibers may be converted into bending, and the fiber sliver will be twisted into a braid shape.

[0003] Cable filling ropes are used to fill the gaps between cables during cable production. The finished cable filling ropes have been twisted before leaving the factory, but the twisting degree of common filling ropes is low, making the filling ropes relatively loose and not conducive to filling the gaps between cables.

[0004] The utility model with the patent number CN217678301U discloses a filling rope twisting device, which includes an overall device, a rotating mechanism and a fixing mechanism. The bottom of the overall device is fixedly connected with a bottom plate. The right side of the top of the bottom plate is fixedly connected with a rotating mechanism. The right side of the rotating mechanism is fixedly connected with a support rod. The left side of the top of the support rod is fixedly connected with a first motor. The left side of the first motor is movably connected with a turntable. The inner side of the left side of the turntable is embedded and connected with a limit chute. The inner side of the limit chute is movably connected with a pressing block. The middle top of the pressing block is movably connected with an elastic clip. The left side of the top of the bottom plate is movably connected with a fixing mechanism. The middle of the fixing mechanism is movably connected with a sliding plate. The bottom of the sliding plate is fixedly connected with a connecting block. The inner side of the connecting block is penetrated and connected with a lead screw. The middle of the lead screw is fixedly connected with a limit block. The front of the lead screw is fixedly connected with a rotating rod. The top of the sliding plate is fixedly connected with the back of a second motor, and the back of the second motor is movably connected with a transmission shaft; when a user uses the overall device 1 to twist the filling rope, the user can manually place the filling rope between two pressing blocks 405, and then the elastic clip 406 drives the pressing block 405 to squeeze and fix the shaft in the middle of the filling rope, and thus the filling rope can be driven to rotate after the turntable 403 rotates. Then, the positioning sleeve 3 merges the corresponding number of filling ropes at the corresponding positions, so that the filling rope is twisted and wound. At the same time, the user fixes the reel for winding the finished product to the transmission shaft 503, so that the transmission shaft 503 can drive the reel to wind the twisted filling rope after rotating under the action of the second motor 502; in this patent, multiple groups of filling ropes can be combined and twisted, and it is difficult to twist the already combined and twisted filling ropes a second time.

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] In one embodiment, referring to Figure 1 , an automatic twisting device for a cable stranding filling rope of the present utility model includes a feeding assembly, a suspension assembly and a rotating assembly.

[0024] Among them, the feeding assembly includes a base frame 1 and a feeding tray 2 rotatably arranged on the base frame 1. An inner core rod 3 is arranged on the feeding tray 2, and spiral blades 4 are arranged on the outer wall of the inner core rod 3; the suspension assembly includes a first suspension rod 5, a second suspension rod 6 and a third suspension rod 7 arranged at intervals on the base frame 1. A first pulley 8 is rotatably arranged on the first suspension rod 5, multiple groups of second pulleys 9 are fixedly and spacedly arranged on the second suspension rod 6, and a third pulley 10 is rotatably arranged on the third suspension rod 7; the rotating assembly includes a driving worm 11 arranged on the second suspension rod 6 and a driving worm gear 12 arranged on the feeding tray 2, and the driving worm 11 meshes with the driving worm gear 12; the wire end of the filling rope passes through the spiral blades 4 and is wound around the first pulley 8, one of the groups of second pulleys 9 and the third pulley 10 in sequence, and then passes out through the other group of second pulleys 9. The wire end of the filling rope moves away from the feeding tray 2 under the action of an external force to drive the second pulley 9 to rotate, thereby causing the second suspension rod 6 to rotate and drive the driving worm 11 to mesh with the driving worm gear 12, so that the feeding tray 2 rotates to twist the filling rope.

[0025] Further, referring to Figure 1, two sets of support plates 13 are arranged on the chassis 1 at intervals, and the two sets of support plates 13 are on the same horizontal plane; a rotating shaft 14 is provided on the material feeding tray 2, a roller shaft 15 is provided inside the material feeding tray 2, and a feeding port 16 is provided on the material feeding tray 2; the rotating shaft 14 is rotatably installed on the support plate 13.

[0026] Preferably, the chassis 1 is of a "U" - shaped structure, the two sets of support plates 13 are located at the upper end of the chassis 1, the support plates 13 are provided with rotating holes, and rotating bearings 17 are provided in the rotating holes. The rotating shaft 14 is fixedly connected to the inner ring of the rotating bearing 17.

[0027] Furthermore, referring to Figure 1 , one end of the material feeding tray 2 facing the first suspension rod 5 is provided with a wire outlet hole; two sets of roller shafts 15 are provided, and there is a space between the two sets of roller shafts 15. One set of roller shafts 15 is connected to the material feeding tray 2 by threads.

[0028] Preferably, the material feeding tray 2 is a hollow cylinder, and the feeding port 16 is arranged on the side wall of the material feeding tray 2.

[0029] In the above - mentioned setting, the wrapped finished product filling rope is put into the material feeding tray 2 from the feeding port 16, and the roller shaft 15 connected to the material feeding tray 2 by threads is rotated, so that the two sets of roller shafts 15 are inserted into the middle of the finished product filling rope. The placing direction of the finished product filling rope needs to be determined according to the rotating direction of the material feeding tray 2 to ensure that the filling rope can be twisted during the rotation of the material feeding tray 2 instead of being scattered; after the finished product filling rope is placed, the wire end of the traction finished product filling rope enters the spiral blade 4.

[0030] Furthermore, referring to Figure 1 、 2 , the inside of the rotating shaft 14 is hollow, the inner core rod 3 is fixedly connected to the rotating shaft 14, and a wire loop 18 is provided at one end of the inner core rod 3 away from the material feeding tray 2.

[0031] Preferably, the inner core rod 3 is arranged close to the center of the rotating shaft 14.

[0032] In the above - mentioned setting, after the wire end of the filling rope is pulled out from the wire outlet hole, it passes through the inside of the rotating shaft 14, winds around the spiral blade 4 and passes through the wire loop 18. During the rotation of the material feeding tray 2, it can ensure that the filling rope is always on the outer wall of the spiral blade 4 and can be twisted by the spiral blade 4.

[0033] Furthermore, referring to Figure 1 、 3 , the first suspension rod 5 and the center of the inner core rod 3 are on the same horizontal plane, and the position of the first pulley 8 is directly opposite to the extension line of the inner core rod 3; the second suspension rod 6 and the third suspension rod 7 are on the same horizontal plane and are located lower than the first suspension rod 5.

[0034] Preferably, the second suspension rod 6 and the third suspension rod 7 are located below the material feeding tray 2.

[0035] Preferably, two sets of the second pulleys 9 are arranged at intervals, and rubber sleeves are sleeved on the two sets of the second pulleys 9.

[0036] In the above setting, the wire end of the filling rope passes through the first pulley 8 and then winds around one set of the second pulleys 9. At this time, the filling rope between the first pulley 8 and the second pulley 9 is in an inclined state, and there is a frictional force between this end of the filling rope and the first pulley 8 and the second pulley 9; the wire end that winds around the first set of the second pulleys 9 winds around the third pulley 10, and then turns back and winds around the other set of the second pulleys 9. Through two windings, the contact area between the filling rope and the two sets of the second pulleys 9 is increased. At the same time, the rubber sleeve can increase the frictional force between the filling rope and the second pulley 9. When pulling the wire end of the filling rope, it is ensured that the filling rope can transfer the acting force to the second suspension rod 6 during the movement process, so that the second suspension rod 6 rotates, and further drives the transmission worm 11 to mesh with the transmission worm wheel 12, so as to rotate the feeding tray 2 for secondary twisting of the filling rope.

[0037] Preferably, the feeding tray 2, the inner core rod 3, the first suspension rod 5, the second suspension rod 6, the third suspension rod 7, the first pulley 8, the second pulley 9, the third pulley 10, the transmission worm 11, and the transmission worm wheel 12 can be made of lightweight materials such as polytetrafluoroethylene to reduce the overall weight and facilitate driving the feeding tray 2 to rotate for secondary twisting when pulling the filling rope to move.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
