Description

Technical Field

[0001] This invention belongs to the field of cable processing technology, specifically a cable stranding machine. Background Technology

[0002] As a core connecting component in the electrical, communication, and automotive electronics fields, the processing quality of wire harnesses directly affects signal transmission stability and equipment lifespan. Stranding machines are key equipment in wire harness production, used to bundle multiple wires together at a specified pitch to improve the mechanical strength, flexibility, and anti-interference capabilities of the wire harness.

[0003] However, the conductors of common cable stranding machines are prone to bending and deformation during the unwinding, conveying and stranding process. Traditional equipment often uses fixed guide wheels or simple straightening structures, which cannot simultaneously complete continuous straightening and untwisting, resulting in poor quality of cable products after stranding and winding. Summary of the Invention

[0004] The purpose of this invention is to provide a cable stranding machine in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A cable stranding machine includes a base plate, a left side plate and a right side plate are fixedly installed on the top left and right sides of the base plate respectively, a left main shaft is rotatably installed at the central axis of the left side plate, a left mounting plate is fixedly connected to the outer side of the left main shaft, a right main shaft is rotatably installed at the central axis of the right side plate, a right mounting plate is fixedly connected to the outer side of the right main shaft, and a straightening and un-twisting assembly is fixedly installed on both the left and right mounting plates.

[0006] By adopting the above technical solution, the straightening and un-twisting assembly is integrated between the left and right mounting plates during equipment operation, making the equipment structure more compact and improving its neatness and aesthetics. Two sets of parallel un-twisting wheel mounting plates are installed between the left and right un-twisting shafts, and multiple sets of un-twisting straightening wheels are arranged between these plates. The cable passes through these wheels sequentially to achieve straightening. During straightening, the un-twisting motor and the hinged drive motor rotate synchronously in opposite directions. Combined with the transmission of the un-twisting drive pulley, un-twisting belt, and un-twisting transmission pulley, these components drive the left un-twisting shaft, the un-twisting wheel mounting plate, and the right un-twisting shaft to rotate synchronously. This synchronously rotates the cable held by the un-twisting straightening wheels, allowing the cable to rotate in the opposite direction for synchronous un-twisting. This ensures that the cable un-twisting and straightening processes are completed simultaneously, effectively eliminating internal torsional stress in the cable. Furthermore, the use of multiple wheel sets enhances the cable straightening effect, ensuring straightness and improving the quality of the output cable.

[0007] In a preferred embodiment, the straightening and unwinding assembly includes a left unwinding fixed shaft, an unwinding motor, a right unwinding fixed shaft, a left unwinding rotating shaft, an unwinding transmission pulley, an unwinding belt, an unwinding drive pulley, an unwinding sheave mounting plate, a right unwinding rotating shaft, and an unwinding straightening wheel; wherein, The left and right unwinding fixed shafts are respectively fixedly mounted on the left and right mounting plates. The right side of the left unwinding fixed shaft is rotatably connected to the left unwinding rotating shaft, and the left side of the right unwinding fixed shaft is rotatably connected to the right unwinding rotating shaft. Two sets of parallel unwinding sheave mounting plates are fixedly mounted between the left and right unwinding rotating shafts. Multiple sets of unwinding straightening pulleys are rotatably mounted between the two sets of unwinding sheave mounting plates. An unwinding transmission pulley is fixedly mounted on the outer side of the left unwinding rotating shaft. An unwinding motor is also fixedly mounted on the left mounting plate. An unwinding drive pulley is fixedly mounted on the output end of the unwinding motor. An unwinding belt is sleeved on the outer side of both the unwinding drive pulley and the unwinding transmission pulley.

[0008] By adopting the above technical solution, the cable un-twisting and straightening processes can be synchronized by passing the wire harness sequentially through the wire hole inside the left un-twisting fixed shaft, the wire hole inside the left un-twisting moving shaft, between multiple sets of un-twisting straightening wheels, the wire hole inside the right un-twisting moving shaft, and the wire hole through the right un-twisting fixed shaft. This can effectively eliminate the internal torsional stress of the cable, and the quality of the output wire can be improved by the cooperation of multiple sets of wheels.

[0009] In a preferred embodiment, a take-up motor is fixedly connected to the right end of the left main shaft, and a left fixed plate is fixedly connected to the output end of the take-up motor. A right fixed plate is rotatably connected to the left end of the right main shaft, and the take-up reel is clamped together between the left fixed plate and the right fixed plate.

[0010] By adopting the above technical solution, the left and right fixed plates clamp the cable together, and the winding motor and the bow drive motor rotate in opposite directions synchronously, ensuring that the take-up reel remains relatively stationary, which facilitates the winding and bundling of the cable.

[0011] In a preferred embodiment, a drive wheel is fixedly sleeved on the outer side of the left main shaft, and a transmission wheel is fixedly connected to the outer side of the right main shaft. A wire guide bow and a counterweight bow are fixedly provided between the drive wheel and the transmission wheel. The wire guide bow and the counterweight bow are symmetrically arranged about the central axes of the right main shaft and the left main shaft.

[0012] By adopting the above technical solution, and by setting up symmetrical wire-passing bows and counterweight bows about the central axes of the right and left main shafts, the stability of the equipment operation can be guaranteed.

[0013] In a preferred embodiment, a hinge drive motor is fixedly mounted on the side of the left side plate, a hinge drive pulley is fixedly mounted on the output end of the hinge drive motor, a hinge transmission pulley is fixedly mounted on the outer side of the drive wheel, and a hinge drive belt is sleeved on the outer side of both the hinge transmission pulley and the hinge drive pulley.

[0014] By adopting the above technical solution, the drive motor of the bow drive, in conjunction with the drive pulley of the bow, the drive belt of the bow and the transmission pulley of the bow, drives the drive wheel to rotate, and then winds and rotates the wire harness through the wire guide bow and the counterweight bow.

[0015] In a preferred embodiment, a cable tray is fixedly installed on the right side of the right side plate, and a cable tensioning membrane is provided at the central axis of the right side spindle, with the cable tensioning membrane corresponding to the cable tray.

[0016] By adopting the above technical solution, through the setting of the cable tray and the right spindle, the rotation of the right spindle cooperates with the twisted wire eye membrane opened on the inner side to wind the wire bundle.

[0017] In a preferred embodiment, a threading hole is provided at the central axis of both the left and right retraction torsion shafts, and a thread-passing hole is provided on the inner side of both the left and right retraction torsion fixing shafts, with the thread-passing hole corresponding to the threading hole.

[0018] By adopting the above technical solution, and by setting the wire guide hole and the wire threading hole in a corresponding manner, it is convenient to straighten and untwist the wire harness simultaneously, thereby improving the compactness of the equipment.

[0019] In a preferred embodiment, a lead screw is rotatably connected to the middle of the left mounting plate and the right mounting plate. A translation wheel is threaded to the outer side of the lead screw. The end of the lead screw is fixedly mounted to a translation wheel motor, and the translation wheel motor is fixedly mounted on the right mounting plate.

[0020] By adopting the above technical solution, the spool translation motor is started, which drives the lead screw to rotate. Through the threaded engagement of the lead screw and the translation spool, the translation spool is driven to move horizontally, ensuring the flatness of the wire harness winding.

[0021] In a preferred embodiment, a plurality of fixed reel sets are also fixedly provided on the right side of the left mounting plate.

[0022] By adopting the above technical solution and setting up multiple fixed cable reel sets, the cables can be guided, ensuring the stable operation of the equipment.

[0023] In a preferred embodiment, the unwinding motor and the bow drive motor rotate synchronously in opposite directions, and the bow drive motor and the winding motor rotate synchronously.

[0024] By adopting the above technical solution, the unwinding motor and the bow drive motor rotate synchronously in opposite directions, ensuring the synchronicity of cable unwinding and improving cable quality.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: During operation, the integrated straightening and untorsion assembly between the left and right mounting plates makes the equipment structure more compact and improves its neatness and aesthetics. Two parallel untorsion wheel mounting plates are installed between the left and right untorsion shafts, and multiple untorsion straightening wheels are arranged between these plates. The cable passes through these wheels sequentially for straightening. During straightening, the untorsion motor and the hinge drive motor rotate synchronously in opposite directions. This, combined with the transmission of the untorsion drive pulley, untorsion belt, and untorsion transmission pulley, drives the left and right untorsion shafts, the untorsion wheel mounting plates, and the right untorsion shaft to rotate synchronously. This synchronously rotates the cable held by the untorsion straightening wheels, causing the cable to rotate in the opposite direction for synchronous untorsion. This allows the cable untorsion and straightening processes to be completed simultaneously, effectively eliminating internal torsional stress in the cable. Furthermore, the use of multiple wheels enhances the straightening effect, ensuring straightness and improving the quality of the output cable. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0029] Reference Figure 1-6 A cable stranding machine includes a base plate 1. A left side plate 2 and a right side plate 3 are fixedly installed on the top left and right sides of the base plate 1, respectively. A left main shaft 4 is rotatably installed at the central axis of the left side plate 2. A left mounting plate 5 is fixedly connected to the outside of the left main shaft 4. A right main shaft 7 is rotatably installed at the central axis of the right side plate 3. A right mounting plate 10 is fixedly connected to the outside of the right main shaft 7. A straightening and un-twisting assembly 8 is fixedly installed on both the left mounting plate 5 and the right mounting plate 10.

[0030] During operation, the straightening and un-twisting assembly 8 is integrated between the left mounting plate 5 and the right mounting plate 10, making the equipment structure more compact and improving its neatness and aesthetics. Two sets of parallel un-twisting thread pulley mounting plates 808 are installed between the left un-twisting drive shaft 804 and the right un-twisting drive shaft 809, and multiple sets of un-twisting straightening threads 8010 are arranged between the two sets of un-twisting thread pulley mounting plates 808. The cable passes through these multiple sets of un-twisting straightening threads 8010 sequentially to straighten it. During straightening, the un-twisting motor 802 and the bow drive motor 22 ensure simultaneous operation. The reverse rotation, in conjunction with the un-torsion drive pulley 807, un-torsion belt 806, and un-torsion transmission pulley 805, drives the left un-torsion drive shaft 804, un-torsion cable wheel mounting plate 808, and right un-torsion drive shaft 809 to rotate synchronously. This synchronously drives the cable held by the un-torsion straightening wheel 8010 to rotate, thereby driving the cable to rotate in the opposite direction for synchronous un-torsion. This allows the cable un-torsion and straightening processes to be completed simultaneously, effectively eliminating internal torsional stress in the cable. Furthermore, the cooperation of multiple wheel sets enhances the cable straightening effect, ensuring the straightness of the output cable and improving the quality of the output cable.

[0031] The straightening and torsion-reversing assembly 8 includes a left torsion-reversing fixed shaft 801, a torsion-reversing motor 802, a right torsion-reversing fixed shaft 803, a left torsion-reversing moving shaft 804, a torsion-reversing transmission pulley 805, a torsion-reversing belt 806, a torsion-reversing drive pulley 807, a torsion-reversing sheave mounting plate 808, a right torsion-reversing moving shaft 809, and a torsion-reversing straightening wheel 8010; wherein, The left retraction torque fixing shaft 801 and the right retraction torque fixing shaft 803 are respectively fixedly mounted on the left mounting plate 5 and the right mounting plate 10. The right side of the left retraction torque fixing shaft 801 is rotatably connected to the left retraction torque shaft 804, and the left side of the right retraction torque fixing shaft 803 is rotatably connected to the right retraction torque shaft 809. Two sets of parallel retraction torque pulley mounting plates 808 are fixedly mounted between the left retraction torque shaft 804 and the right retraction torque shaft 809. Multiple sets of retraction torque straightening pulleys 8010 are rotatably mounted between the two sets of retraction torque pulley mounting plates 808. A retraction torque transmission pulley 805 is fixedly mounted on the outer side of the left retraction torque shaft 804. A retraction torque motor 802 is also fixedly mounted on the left mounting plate 5. A retraction torque drive pulley 807 is fixedly mounted on the output end of the retraction torque motor 802. A retraction torque belt 806 is sleeved on the outer side of the retraction torque drive pulley 807 and the retraction torque transmission pulley 805.

[0032] By sequentially passing the wire harness through the wire hole inside the left un-torsion fixed shaft 801, the wire hole inside the left un-torsion moving shaft 804, between multiple sets of un-torsion straightening wheels 8010, the wire hole inside the right un-torsion moving shaft 809, and the wire hole through the right un-torsion fixed shaft 803, the un-torsion and straightening processes of the cable can be synchronized. This can effectively eliminate the internal torsional stress of the cable, and the quality of the output wire can be improved through the cooperation of multiple sets of wheels.

[0033] The left main shaft 4 has a take-up motor fixedly connected to its right end, and a left fixed plate 14 is fixedly connected to the output end of the take-up motor. The right main shaft 7 has a right fixed plate 13 rotatably connected to its left end. The take-up reel 15 is clamped between the left fixed plate 14 and the right fixed plate 13. By clamping the take-up reel 15 together with the left fixed plate 14 and the right fixed plate 13, and with the synchronous counter-rotation of the take-up motor and the bow drive motor 22, the take-up reel 15 can be kept relatively stationary, which facilitates the winding and bundling of the cable.

[0034] A drive wheel 9 is fixedly sleeved on the outer side of the left main shaft 4, and a transmission wheel 21 is fixedly connected to the outer side of the right main shaft 7. A wire guide bow 11 and a counterweight bow 12 are fixedly mounted between the drive wheel 9 and the transmission wheel 21. Both the wire guide bow 11 and the counterweight bow 12 are symmetrically arranged about the central axes of the right main shaft 7 and the left main shaft 4. By symmetrically arranging the wire guide bow 11 and the counterweight bow 12 about the central axes of the right main shaft 7 and the left main shaft 4, the stability of the equipment operation can be ensured.

[0035] A hinge drive motor 22 is fixedly mounted on the side of the left side plate 2. A hinge drive pulley 20 is fixedly mounted on the output end of the hinge drive motor 22. A hinge transmission pulley 23 is fixedly mounted on the outer side of the drive wheel 9. A hinge drive belt 24 is fitted around the outer sides of the hinge transmission pulley 23 and the hinge drive pulley 20. By driving the hinge drive motor 22, in conjunction with the transmission of the hinge drive pulley 20, the hinge drive belt 24, and the hinge transmission pulley 23, the drive wheel 9 is driven to rotate. Then, the wire harness is wound and rotated through the wire guide hinge 11 and the counterweight hinge 12.

[0036] A cable tray 25 is fixedly installed on the right side of the right side plate 3, and a stranding eye 6 is provided at the central axis of the right side spindle 7, corresponding to the cable tray 25. Through the arrangement of the cable tray 25 and the right side spindle 7, the right side spindle 7 rotates to cooperate with the stranding eye 6 on the inner side to wind the wire harness.

[0037] Both the left retraction torsion shaft 804 and the right retraction torsion shaft 809 have wire-passing holes at their central axes. The left retraction torsion fixing shaft 801 and the right retraction torsion fixing shaft 803 have wire-passing holes on their inner sides, with the wire-passing holes corresponding to the wire-passing holes. This correspondence between the wire-passing holes and the wire-passing holes facilitates the simultaneous straightening and retraction of the wire harness, improving the compactness of the equipment.

[0038] A lead screw 17 is rotatably connected between the left mounting plate 5 and the right mounting plate 10. A translation wheel 19 is threadedly connected to the outer side of the lead screw 17. The end of the lead screw 17 is fixedly mounted to a translation wheel motor 18, which is fixedly mounted on the right mounting plate 10. When the translation wheel motor 18 is started, it drives the lead screw 17 to rotate. Through the threaded engagement between the lead screw 17 and the translation wheel 19, the translation wheel 19 is driven to move horizontally, ensuring the flatness of the wire harness winding.

[0039] Multiple cable reel sets 16 are also fixedly installed on the right side of the left mounting plate 5. By setting multiple cable reel sets 16, the cables can be guided to ensure the stable operation of the equipment.

[0040] The unwinding motor 802 and the bow drive motor 22 rotate synchronously in opposite directions, while the bow drive motor 22 and the winding motor rotate synchronously. By ensuring that the unwinding motor 802 and the bow drive motor 22 rotate synchronously in opposite directions, the synchronicity of cable unwinding is guaranteed, thus improving cable quality.

[0041] The implementation principle of the cable stranding machine of the present invention is as follows: First, the wire bundle passes through the cable collector plate 25, enters the stranding eye 6 opened in the right main shaft 7, passes through the wire hole on the wire guide bow 11, enters the interior of the left main shaft 4, exits from the interior of the left main shaft 4, and is wound on the fixed wire wheel group 16. Then, it passes through the wire guide hole opened in the inner side of the left un-twist fixed shaft 801 and the wire through hole opened in the left un-twist moving shaft 804. It passes through multiple sets of un-twist straightening wheels 8010 between the un-twist wire wheel mounting plates 808, and exits through the wire through hole opened in the inner side of the right un-twist moving shaft 809 and the wire guide hole opened in the inner side of the right un-twist fixed shaft 803, thus completing the straightening and un-twist of the cable. The cable that has passed through passes through the translation wheel 19 and is wound on the take-up wheel 15 to complete the winding.

[0042] Start the bow drive motor 22, which, in conjunction with the bow drive pulley 20, bow transmission pulley 23, and bow drive belt 24, drives the drive wheel 9 to rotate. Through the connection of the wire guide bow 11 and the counterweight bow 12, and the fixed installation of the drive wheel 9 and the left main shaft 4, the left mounting plate 5 is driven to rotate, which synchronously drives the transmission wheel 21, the right main shaft 7, and the right mounting plate 10 to rotate. The right main shaft 7 rotates and passes through the stranded wire eye 6, allowing the cable to pass through the wire hole on the inside of the wire guide bow 11.

[0043] The un-torque motor 802 is started synchronously. The un-torque motor 802 and the hinge drive motor 22 ensure synchronous reverse rotation. With the transmission of the un-torque drive pulley 807, the un-torque belt 806, and the un-torque transmission pulley 805, the left un-torque drive shaft 804, the un-torque pulley mounting plate 808, and the right un-torque drive shaft 809 are driven to rotate synchronously. Through the multiple sets of un-torque straightening pulleys 8010 set inside the un-torque pulley mounting plate 808, the cable can be straightened. The un-torque pulley mounting plate 808 drives the un-torque straightening pulleys 8010 to rotate, which can drive the cable inside the un-torque straightening pulleys 8010 to un-torque synchronously.

[0044] The starting wheel translation motor 18 drives the lead screw 17 to rotate, which in turn drives the translation wheel 19 to move. Through the translation wheel 19, the cable moves and can be evenly wound on the take-up wheel 15.

[0045] Start the winding motor, which drives the left fixed plate 14 to rotate in the opposite direction, thereby driving the take-up reel 15 to remain relatively stationary.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
