DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a wire twisting device and a production method for multi-strand cables. Example

[0022] See also Figure 1 - Figure 8 A wire twisting device includes a workbench body 1, a wire twisting mechanism 2 is installed on the top of the workbench body 1, a wire installation mechanism 3 is installed outside the wire twisting mechanism 2, a twisting drive mechanism 4 is installed inside the workbench body 1, a wire merging mechanism 5 is installed on the top of the workbench body 1, and a wire moving mechanism 6 is installed on the top of the workbench body 1; The top of the twisting drive mechanism 4 passes through the workbench body 1 and is transmission-connected to the wire twisting mechanism 2, and the bottom of the wire installation mechanism 3 passes through the twisting drive mechanism 4 and is connected to the twisting drive mechanism 4; The wire twisting mechanism 2 can pull and gather the wires on the wire installation mechanism 3, the twisting drive mechanism 4 can drive the wire twisting mechanism 2 to rotate, and when the wire twisting mechanism 2 rotates, it can drive the wires to rotate and twist the wires, the wire installation mechanism 3 can control the wire unwinding speed, the wire installation mechanism 3 can control the transmission connection inside the twisting drive mechanism 4, and the wire merging mechanism 5 and the wire moving mechanism 6 can guide and move the wires after twisting.

[0023] When twisting the wires, the central wire of the multi-strand cable passes through the center of the wire twisting mechanism 2, the wire merging mechanism 5 and the wire moving mechanism 6 in turn and is connected to other external equipment, while the other wires are installed on the wire installation mechanism 3. When twisting the cables, the twisting drive mechanism 4 can drive the wire twisting mechanism 2 and the wire installation mechanism 3 to rotate, and during the rotation process, the wires on the wire installation mechanism 3 can be twisted outside the central wire through the guidance and rotation of the wire twisting mechanism 2, and the multi-strand wires are always kept in a tensioned state during the twisting process. In the production process of the multi-strand cable, one of the wires is twisted. When a break occurs, the wire installation mechanism 3 can move outside the wire twisting mechanism 2, and the wire installation mechanism 3 can change the transmission connection relationship inside the twisting drive mechanism 4 when moving outside the wire twisting mechanism 2. After the connection relationship inside the twisting drive mechanism 4 is changed, the twisting drive mechanism 4 no longer drives the wire twisting mechanism 2 to rotate. After the wire twisting mechanism 2 stops rotating, the wire twisting production work also stops. After the wire breaks, the wire production also stops immediately, which can effectively prevent one of the wires from continuing to produce unqualified cables after the break, thereby preventing waste of production materials in the production process. Example

[0024] The difference from the above embodiment is that, please refer to Figure 1 - Figure 8 The wire twisting mechanism 2 includes a turntable mounting seat 21, which is mounted on the top of the workbench body 1. A wire middle turntable 22 is rotatably mounted inside the turntable mounting seat 21, and a plurality of middle turntable rollers 23 are mounted inside the wire middle turntable 22. A turntable connecting cylinder 24 is mounted inside the wire middle turntable 22, and a front wire turntable 25 is mounted outside the turntable connecting cylinder 24. A front turntable roller 26 is mounted inside the front wire turntable 25, a rear wire turntable 27 is mounted outside the turntable connecting cylinder 24, and a rear turntable roller 28 is mounted inside the rear wire turntable 27. A central wire channel 29 is opened inside the turntable connecting cylinder 24.

[0025] The outside of the conductor middle turntable 22 is in driving connection with the twisting drive mechanism 4. The inside of the conductor middle turntable 22 is provided with a plurality of openings for the conductors to pass through. The openings inside the conductor middle turntable 22 are all installed with middle turntable rollers 23. The two sides of the conductor middle turntable 22 are respectively connected to the conductor front turntable 25 and the conductor rear turntable 27 through the turntable connecting tube 24. The twisting drive mechanism 4 can drive the middle turntable 22 of the conductor to rotate inside the turntable mounting seat 21. When the middle turntable 22 of the conductor rotates, it can drive the front turntable 25 of the conductor and the rear turntable 27 of the conductor to rotate through the turntable connecting tube 24. When the middle turntable 22 of the conductor, the front turntable 25 of the conductor and the rear turntable 27 of the conductor rotate, they can drive multiple strands of conductor to rotate synchronously. When the rear turntable 27 of the conductor rotates, it can also drive the conductor mounting mechanism 3 to rotate.

[0026] The wires on the wire installation mechanism 3 pass through the wire rear turntable 27, the wire middle turntable 22 and the wire front turntable 25 in sequence. The wire rear turntable 27, the wire middle turntable 22 and the wire front turntable 25 guide the moving direction of the wires through the central wire channel 29, the middle turntable roller 23 and the front turntable roller 26 respectively. The central wire channel 29 at the center of the turntable connecting cylinder 24 is in the same straight line as the centers of the wire merging mechanism 5 and the wire moving mechanism 6 .

[0027] During the twisting operation of the multi-strand cable, the center conductor passes through the center conductor channel 29 in the center of the turntable connecting cylinder 24, and then passes through the conductor merging mechanism 5 and the conductor moving mechanism 6 in sequence, while the multi-strand conductors inside the conductor installation mechanism 3 on the conductor rear turntable 27 pass through the interiors of the conductor rear turntable 27, the conductor middle turntable 22 and the conductor front turntable 25 respectively, and when the multi-strand conductors pass through the interiors of the conductor rear turntable 27, the conductor middle turntable 22 and the conductor front turntable 25, they can also guide the moving direction of the conductor through the center conductor channel 29, the middle turntable roller 23 and the front turntable roller 26, and the conductor is twisted and driven during the twisting process. The mechanism 4 can drive the middle turntable 22 of the wire to rotate. When the middle turntable 22 of the wire rotates, the front turntable 25 of the wire and the rear turntable 27 of the wire connected to the two ends of the turntable connecting tube 24 can be driven to rotate synchronously. When the middle turntable 22 of the wire, the front turntable 25 of the wire and the rear turntable 27 of the wire rotate, the multiple strands of wire can be driven to rotate synchronously outside the center wire. When the multiple strands of wire rotate, they can cover the outside of the center wire. The synchronous rotation of the multiple strands of wire driven by the rotation of the middle turntable 22 of the wire, the front turntable 25 of the wire and the rear turntable 27 of the wire can make the multiple strands of wire evenly distributed outside the center wire, thereby ensuring the production quality of the multiple strands of wire. Example

[0028] The difference from the above embodiment is that, please refer to Figure 1- Figure 8 The wire installation mechanism 3 includes multiple sliding installation frames 31 and multiple fixed limiting frames 33. The sliding installation frames 31 are slidably installed inside the wire rear turntable 27, and the fixed limiting frames 33 are installed outside the fixed limiting frames 33. The wire installation turntable 32 is rotatably installed inside the sliding installation frame 31, and the installation frame spring 34 is installed inside the sliding installation frame 31. The outside of the sliding installation frame 31 is connected to a transmission block 35, the outside of the transmission block 35 is installed with a transmission connecting ring 36, and the outside of the transmission connecting ring 36 is installed with a transmission connecting plate 37.

[0029] A plurality of sliding mounting brackets 31 are distributed in a ring shape inside the conductor rear turntable 27. A conductor mounting turntable 32 is slidably mounted on the outside of the conductor rear turntable 27 via the sliding mounting brackets 31. The inside of the sliding mounting brackets 31 is connected to the outside of the conductor rear turntable 27 via mounting bracket springs 34. The outside of the conductor mounting turntable 32 has a polygonal structure. When the sliding mounting frame 31 moves inside the wire rear turntable 27, it can drive the wire mounting turntable 32 to move inside the fixed limit frame 33. When the mounting frame spring 34 drives the wire mounting turntable 32 to move toward the fixed limit frame 33, it can drive the wire mounting turntable 32 to contact the inside of the fixed limit frame 33. When the wire mounting turntable 32 contacts the inside of the fixed limit frame 33, the fixed limit frame 33 can be clamped with the outside of the wire mounting turntable 32.

[0030] The exteriors of the multiple transmission blocks 35 are in contact with the exteriors of the transmission connection ring 36. The bottom of the transmission connection plate 37 passes through the top of the workbench body 1 and is connected to the twisting drive mechanism 4. The transmission connection ring 36 is slidably installed above the workbench body 1 through the transmission connection plate 37. The exteriors of the transmission blocks 35 are engaged with the exteriors of the transmission connection ring 36. When the sliding mounting frame 31 moves, it can drive the transmission block 35 to move synchronously. When the transmission block 35 moves, it can drive the transmission connecting plate 37 to move inside the workbench body 1. When the transmission connecting plate 37 moves, it can adjust the connection relationship inside the twisting drive mechanism 4.

[0031] The twisting drive mechanism 4 includes a twisting motor 41 and a wheel mounting rod 44. The twisting motor 41 is installed inside the workbench body 1, and the wheel mounting rod 44 is installed on the top inside the workbench body 1. The driving end of the twisting motor 41 is installed with a motor wheel 42, and the outside of the motor wheel 42 is installed with a transmission belt 43. The outside of the wheel mounting rod 44 is installed with a movable wheel 45, and the outside of the wheel mounting rod 44 is installed with a transmission roller 46. The outside of the transmission roller 46 passes through the top of the workbench body 1 and is connected to the outside of the wire middle turntable 22 for transmission.

[0032] The outer portion of the motor wheel 42 is connected to the outer portion of the movable wheel 45 via a transmission belt 43. The outer portion of the movable wheel 45 is rotatably connected to the outer portion of the transmission connecting plate 37. The outer diameters of the wheel mounting rods 44 are different. The twisting motor 41 drives the motor wheel 42 to rotate, which can drive the movable wheel 45 to rotate through the transmission belt 43. When the movable wheel 45 rotates, it can drive the wheel mounting rod 44 to rotate. When the wheel mounting rod 44 rotates, it can drive the transmission roller 46 to rotate. When the transmission roller 46 rotates, it can drive the wire middle turntable 22 to rotate. After the transmission connecting plate 37 drives the movable wheel 45 to move, the rotation of the movable wheel 45 no longer drives the rotation of the wheel mounting rod 44.

[0033] When the twisting motor 41 drives the motor wheel 42 to rotate, the external transmission belt 43 can be used to drive the movable wheel 45 to rotate. When the movable wheel 45 rotates, the wheel mounting rod 44 can be driven to rotate. When the wheel mounting rod 44 rotates, the transmission roller 46 can be driven to rotate. When the transmission roller 46 rotates, the middle turntable 22 of the wire can be driven to rotate inside the turntable mounting seat 21, thereby driving the front turntable 25 of the wire and the rear turntable 27 of the wire to rotate synchronously, so as to drive multiple wires to be twisted on the outside of the central wire. When the external device drives the central wire to move inside the wire merging mechanism 5 and the wire moving mechanism 6, it can be driven by traction to be wound around the wire mounting turntable. The wires outside 32 gradually disperse, and the pulling during the traction process can always keep the mounting frame spring 34 in a relaxed state. If one of the strands of wire is broken during the twisting of multiple wires, the wire mounting turntable 32 connected to the wire loses the traction of the wire, and the mounting frame spring 34 contracts to drive the sliding mounting frame 31 to move toward the fixed limit frame 33. When the sliding mounting frame 31 moves toward the fixed limit frame 33, it can drive the wire mounting turntable 32 to move synchronously toward the fixed limit frame 33. When the wire mounting turntable 32 moves toward the fixed limit frame 33, the polygonal structure outside the wire mounting turntable 32 can be aligned with the inner part of the fixed limit frame 33. When the wire installation turntable 32 is clamped with the inner part of the fixed limit frame 33, the wire installation turntable 32 cannot continue to rotate to loosen the wire. When the sliding mounting frame 31 moves toward the fixed limit frame 33, it can also drive the transmission block 35 connected thereto to move toward the fixed limit frame 33. When the transmission block 35 moves toward the fixed limit frame 33, it can drive the transmission connecting ring 36 to move synchronously. When the transmission connecting ring 36 moves toward the fixed limit frame 33, it can drive the transmission connecting plate 37 to move inside the workbench body 1 toward the fixed limit frame 33. When the transmission connecting plate 37 moves, it can drive the movable wheel 45 to rotate from When the thicker outer part of the wheel mounting rod 44 moves, the thinner outer part of the wheel mounting rod 44 moves, and when the movable wheel 45 is at the thicker outer part of the wheel mounting rod 44, the rotation of the movable wheel 45 can drive the wheel mounting rod 44 to rotate synchronously, and when the movable wheel 45 is at the thinner outer part of the wheel mounting rod 44, the rotation of the movable wheel 45 no longer drives the wheel mounting rod 44 to rotate. At this time, the rotation of the movable wheel 45 no longer drives the transmission roller 46 to rotate, so that the twisting drive mechanism 4 stops driving the wire twisting mechanism 2 to rotate, thereby stopping the twisting operation of the wire, which can prevent the production of unqualified products and the waste of other materials caused by the breakage of a wire. Example

[0034] A method for producing a multi-strand cable, using a conductor twisting device according to the first to third embodiments, comprises the following steps: First, pass the center wire through the center of the wire twisting mechanism 2, the wire merging mechanism 5 and the wire moving mechanism 6 in sequence; Then, the stranding drive mechanism 4 drives the conductor stranding mechanism 2 and the conductor installation mechanism 3 to rotate and strand the multiple conductors outside the central conductor. When one of the wires breaks, the wire installation mechanism 3 can be moved outside the wire twisting mechanism 2; When the wire installation mechanism 3 moves outside the wire twisting mechanism 2, it can drive the passing relationship inside the twisting drive mechanism 4 to change; After the transmission relationship inside the twisting drive mechanism 4 changes, the twisting drive mechanism 4 no longer drives the wire twisting mechanism 2 to rotate.
